Checking a car before a long trip: a complete guide

A long car trip is not only an adventure, but also a serious test for your car. Even if the car looks perfect, hidden problems can appear at the most inopportune moment: in the middle of the highway, in a mountainous area or on a deserted stretch of road. According to statistics traffic police, up to 30% of breakdowns on the road occur due to late diagnostics before the trip.

This article is not just a list of recommendations, but practical guide with specific steps that will help you avoid common mistakes. We will look at checking all critical systems: from the oil level to the condition of the brake pads, and also tell you which little things (for example, a spare tire or a first aid kit) are often forgotten to check. At the end you will find unique printable checklist, which will simplify your travel preparations.

1. Engine and technical fluids: what to check first

The engine is the heart of the car, and its condition directly affects the safety of the trip. Start by checking oil level: Even if you recently changed it, a long trip may require topping up. Use the dipstick (on a cold engine!) and compare the level with the marks MIN and MAX. If the oil is dark or contains metal shavings, this is a signal that it needs to be replaced.

Other fluids are no less important:

• 🔥 Coolant: Check the level in the expansion tank. On Volkswagen and Skoda it should be between the marks MIN and MAX, on Toyota - slightly above the middle. The color of the liquid should not be rusty.
• 🛢️ Brake fluid: its level drops as the pads wear, but if it is below normal, look for leaks. On Hyundai and Kia the tank is usually transparent, on Renault - with a cover under the hood.
• ⚡ Power steering fluid (if any): if there is a lack of it, the steering wheel will be tight. On Ford Focus the tank is located on the right, on Lada Vesta - left.

Pay special attention drive belts (generator, timing belt). On cars with more than 100,000 km, belts often crack or stretch. For example, on Honda CR-V In 2018, a broken timing belt can lead to bent valves - repairs will cost 150,000+ rubles.

⚠️ Attention: If you find an oil or coolant leak but can't find the source, don't risk driving any further. On diesel engines (for example, BMW 320d) even a small leak can lead to overheating and major repairs.

2. Brake system: how to avoid failure at speed

Brakes are your main insurance on the road. Start with a visual inspection brake pads through the spokes of the wheel rim. If the thickness of the friction layer is less than 3–4 mm (at Nissan Qashqai this can be seen without removing the wheel), the pads need to be replaced urgently. On Audi and Mercedes there are often wear sensors - if the icon on the dashboard is lit (!), this is a signal to action.

Next check:

• 🩹 Brake discs: They should not have deep grooves or cracks. For example, on Toyota RAV4 In 2020, the permissible disc thickness is at least 22 mm.
• 💧 Brake fluid leaks: Inspect hoses and cylinders. On Volvo XC60 Leaks often occur in the rear calipers.
• 🚦 Handbrake: It should keep the car on a slope of 20-25%. You can check it in a parking lot with a slight slope.

If you hear a creaking or vibration when braking, this is a sign uneven wear discs or pads. On Kia Sportage In 2019, this problem often occurs due to corrosion of the caliper guides. The solution is cleaning and lubrication caliper lubricant (not ordinary Litholom!).

3. Wheels and tires: why “bald” tires are dangerous even in summer

The tires are the vehicle's only contact with the road, and their condition determines handling. Start by checking pressure: It must comply with the manufacturer's recommendations (usually found on a sticker on the driver's door or in the glove compartment). For example, for Skoda Octavia 2023 is the norm 2.2 bar front and 2.0 bar rear when fully loaded.

Next, inspect:

• 🔍 Tread depth: the minimum allowable is 1.6 mm for summer tires and 4 mm for winter tires. On Michelin Pilot Sport 4 Wear can be checked by indicators in the grooves.
• 🚗 Side cuts or blisters: Even minor damage can cause rupture at speed. Especially relevant for tires Nokian Hakka after 5 years of operation.
• 🔄 Wheel balancing: If you feel the steering wheel wobbling at a speed of 100+ km/h, the wheel is unbalanced. On Ford Mustang this often happens after changing tires.

Don't forget about spare wheel! According to statistics, 40% of drivers carry a spare tire with a pressure below 1.0 bar or without pressure at all. You can check it only by removing it from the mount - on Toyota Camry it is often hidden under the trunk floor.

Parameter	Standard for a passenger car	What happens if there is a violation?
Tire pressure	2.0–2.4 bar (see manual)	Increased fuel consumption, deterioration in handling
Tread depth	≥1.6 mm (summer), ≥4 mm (winter)	Fine 500 rub. + risk of aquaplaning
Tire life	Up to 10 years (even if the tread is normal)	Rubber loses elasticity, risk of explosion at speed
Balancing	There is no steering wheel runout at speeds of 100+ km/h	Accelerated wear of the suspension, driving discomfort

⚠️ Attention: If you are traveling to mountainous areas (for example, Caucasus or in Crimea), tire pressure needs to be increased by 0.2–0.3 bar. This will reduce the risk of rubber overheating on serpentines. But do not exceed the maximum pressure indicated on the sidewall of the tire!

4. Electrics and lighting: why a “blinking” headlight is dangerous

Electrical problems can leave you without lights, a signal, or even an engine. Start by checking battery:

• 🔋 The voltage at the terminals when the engine is off should be 12.6–12.8 V. If less 12.0 V - the battery is low.
• 🔌 Inspect the terminals: oxidation (white coating) increases resistance. On Renault Duster this often leads to startup problems.
• 🔄 Check the generator: when the engine is running, the voltage should be 13.8–14.4 V. On Lada Granta A faulty alternator is a common cause of “sudden” battery discharge.

Next test all light sources:

• 💡 Headlights: low/high beam, dimensions, turn signals. On Audi A4 PTF lamps often burn out due to moisture ingress.
• 🚨 Brake lights: Have an assistant press the brake pedal. On Hyundai Solaris 2021, sometimes one of the stops fails due to oxidation of the contacts.
• 🔦 Fog lights: Check both front and rear. In some countries (for example, Germany) Driving with the PTFs on is mandatory in bad weather.

Don't forget about fuses! In the fuse box (on Toyota Corolla it's under the hood Volkswagen Polo — in the cabin) there should be no melted or blackened elements. For example, a blown fuse F30 (10A) at Kia Rio turns off the instrument panel lighting.

5. Suspension and steering: how to recognize hidden problems

A worn suspension not only reduces comfort, but also increases braking distance. Take the test:

• 🚗 "Wiggle" of the machine: Press the front fender and release quickly. If the car rocks more than 2 times, the shock absorbers are worn out. On Chevrolet Cruze this often happens after 80,000 km.
• 🔧 Steering wheel play: when the steering wheel is rocked in place, the play should not exceed 10°. On Ford Focus 3 increased play may indicate wear on the steering rack.
• 🛑 Knocks when passing speed bumps: This is a sign of wear on the struts, bushings or silent blocks. On Renault Logan The rear shock absorbers often knock.

Inspect CV joint boots (on front-wheel drive cars): if they are torn, dirt will get inside and the joint will quickly fail. For example, replacing a CV joint with Volkswagen Golf will cost 15,000–20,000 rubles.

If you hear squeaking sound when turning the steering wheel, it could be:

• Wear tie rod ends (on Toyota Corolla 2015 - typical problem).
• Malfunction wheel bearing (on Skoda Rapid often buzzes at speeds of 60+ km/h).
• Low power steering fluid level (at Opel Astra this results in a tight steering wheel).

How to check the wheel bearing?

Raise the car on a jack and spin the wheel by hand. If you hear a crunch or play, the bearing needs to be changed. On Hyundai Tucson 2017 this is a common problem after 100,000 km.

6. Documents and first aid kit: what should be in the car according to the 2026 law

Without the correct documents, you may not be allowed to go abroad or be fined at a traffic police post. Make sure you have:

• 📄 Driver's license (not expired!)
• 🚗 Vehicle registration certificate (or PTS if the car is new).
• 🛡️ OSAGO policy (check validity period and registered drivers). From 2026, driving without compulsory motor liability insurance will be punishable by a fine. 800 rub..
• 🛂 International passport (if you are traveling abroad) + green card (insurance for Europe).

The first aid kit must correspond Order of the Ministry of Health No. 697n (updated in 2023). It must include:

• 🩹 Bandages (at least 2 pieces, one sterile).
• 💊 Painkillers (for example, Ibuprofen or Paracetamol).
• ❄️ Cold pack (for bruises).
• 🩺 Scissors (for cutting clothes or bandages).

Also check warning triangle (there is no expiration date, but it must be clean and visible) and fire extinguisher (volume of at least 2 liters, expiration date - on the label). On gas equipment (if installed) there must be a separate fire extinguisher!

⚠️ Attention: If you are bringing children, be sure to have child seats (by GOST R 41.44-2005). For their absence there is a fine - 3,000 rub.. On Volkswagen Tiguan fastenings ISOFIX must be in good working order (check if the brackets are loose).

7. Additional equipment: what to take on a long journey

In addition to the must-haves, there is a list "saving" little thingsthat will help out in an emergency:

• 🔧 Jack and wheel wrench: Check if they fit your car. On Nissan X-Trail The secret key is often lost.
• 🔋 Starting device (booster): for example, Carku E-Power-3 will help start when the battery is dead.
• 📱 Powerbank (with a capacity of at least 10,000 mAh) + cable for phone. In some regions (for example, in Siberia) connection is only received Megaphone.
• 💧 Supply of water and food: on the highway M5 "Ural" gas stations occur once every 100+ km.
• 🧰 Multitool (for example, Leatherman) for minor repairs.

If you are traveling in winter, add:

• ❄️ Scraper and brush for glass.
• 🧊 Tow rope (length not less than 4 m).
• 🔥 Candles or dry alcohol for heating.

For off-road travel (e.g. UAZ Patriot) will be useful:

• 🏜️ Shovel (folding, made of aluminum).
• 🔗 Tug rope with hooks (load of at least 3 tons).
• 🛢️ Fuel canister (but not more than 20 liters - transportation rules!).

8. Test drive before the trip: what you should be wary of

After all checks, complete control visit for 10–15 km on different types of roads (city, highway, uneven roads). Please note:

• 🚗 Cornering behavior: The car should not “steer” to the side. If the steering wheel pulls to the left, check the wheel alignment or tire pressure.
• 🛑 Braking: The pedal should be elastic, without dips. If the braking distance has increased, look for fluid leaks or pad wear.
• 🔊 Extraneous sounds:
  • Whistling When you press the brake pedal, the pads wear out.
  • Crunch when turning - problems with the CV joint.
  • Knock in the suspension - wear of shock absorbers or silent blocks.
• 🌡️ Engine temperature: The needle should not rise above the middle of the scale. On Mitsubishi Outlander Overheating is often associated with a faulty thermostat.

If you notice at least one of these signs - don't ignore him. For example, vibration when braking at Ford Kuga may indicate deformation of the brake discs, and ignoring the problem will lead to replacing the caliper (price - from 10,000 rubles).

Also check the work air conditioner (especially if you are traveling south) and stoves (relevant for mountainous regions, where the temperature drops to 0°C at night even in summer). On Renault Arkana 2022 climate control often fails due to a malfunction in the control unit.

FAQ: Frequently asked questions before a long trip

❓ Do you need to change the oil before a trip if it’s not time yet?

If there are less than 2,000–3,000 km left before the scheduled replacement, it is better to change the oil in advance. Prolonged engine load (especially in the heat or in the mountains) accelerates oil degradation. For example, on BMW X5 with engine N63 It is recommended to change the oil every 7,000 km during intensive use.

❓ Is it possible to drive summer tires in winter if it’s +5°C outside?

No! At temperatures below +7°C, summer tires lose their elasticity and the braking distance increases by 1.5–2 times. In addition, according to the law (Article 12.5 of the Administrative Code) with December 1 to February 28 Driving on summer tires is punishable by a fine 2,000 rub..

❓ How to check if a fire extinguisher is fake?

The original fire extinguisher must have:

• Labeled with date of manufacture and expiration date.
• Manufacturer's seal (for example, "Rime" or "Yarpozhinvest").
• Instructions in Russian.
• Certificate of conformity (can be checked by number on the website Rosstandart).

Fake fire extinguishers often fail to work at critical times!

❓ What to do if the check engine light comes on while on the road?

If it's on Check Engine, but the car drives fine:

1. Stop and check the oil/coolant level.
2. If everything is normal, go to the nearest service station no sudden acceleration.
3. Use a scanner ELM327 (costs ~500 rubles) to read the error code. For example, P0300 - misfires, P0171 - lean mixture.

On Chevrolet Niva The "check" often lights up due to a faulty oxygen sensor (lambda probe), but you can go.

❓ Do I need to take spare fuses with me?

Yes! Take a set of fuses of different ratings (5A, 10A, 15A, 20A). On Toyota RAV4 The fuse often blows F15 (15A), responsible for the cigarette lighter and radio. Also useful multimeter (for example, DT-830B) to test circuits.
