The first scheduled maintenance, known among motorists as TO-1.This is a critical step in the life of any new vehicle. It is after passing the initial run-in period, which is usually from 1000 to 3000 kilometers, it is necessary to conduct a comprehensive diagnostic of all machine systems. Many owners mistakenly believe that the new car does not require attention, but it is at this stage that hidden assembly defects are revealed and the final grinding of moving parts occurs.
Missing or poor-quality conduct of this event can be a good reason for refusing warranty repairs by the dealer in the future. In the process of operation in the early stages, intense wear of rubbing surfaces occurs, as well as possible weakening of fasteners due to vibration loads. Therefore routine At this stage, they are aimed not only at replacing consumables, but also at a thorough check of the tightness and reliability of the connections.
In this article, we will discuss in detail what is included in the list of mandatory operations, why you can not ignore the manufacturer's recommendations and how to properly prepare the car for a visit to the service center. Understanding these processes will help you avoid imposing unnecessary services and control the quality of work performed by masters.
Time and conditions of guarantee
The time frame for the first service is strictly regulated by the manufacturer and is written in the service book of your car. Usually the interval is 10,000 – 15,000 kilometers of run or 1 year of operation, whichever comes first. Violation of these deadlines even for a few days or hundreds of meters can lead to loss of warranty rightsIn case of a serious breakdown of the engine or transmission will result in enormous financial costs.
It should be noted that the operating conditions in different regions may differ. If the car was used in harsh conditions, such as constant travel on dusty roads, traffic in dense city traffic with frequent stops, or towing a trailer, the intervals may be reduced. In such cases, the dealership may recommend diagnostics before the deadline.
⚠️ Attention: The date of TO-1 is recorded in the dealer’s electronic database and paper service book. The absence of a stamp on the passage of the first service makes it impossible to receive free repairs under warranty in the future, even if the breakdown occurred due to the fault of the plant.
For owners of cars with diesel engines or turbocharged engines, the quality and service life requirements can be even tougher. The turbine requires high-quality lubrication and cooling, and late oil change can lead to coking of oil channels and failure of the unit. Therefore, it is absolutely impossible to ignore the first TO.
Replacement of motor oil and filter elements
The central element of the first maintenance is replacement. motor-oil. During the run-in period, metal shavings accumulate in the oil from rubbing parts of the cylinder-piston group, crankshaft inserts and other nodes. Old oil loses its lubricating and washing properties, becoming an aggressive environment that can damage rubbing fumes.
At the same time as the oil, the oil filter must change. This small element traps large particles of pollution, and by the time TO-1 its throughput can already be significantly reduced. Also, the list of mandatory works often includes the replacement of the air filter, especially if the car was operated in dusty conditions.
The replacement process is as follows:
- 🛢️ Warming up the engine to operating temperature to improve the drainage of the workout.
- 🔧 Unscrewing the drain plug and completely removing the old oil from the pallet.
- 🔄 Dismantling the old oil filter and installing a new one with pre-grease seal.
- 💧 The pouring of new oil is strictly at the level controlled by the probe.
It is important to use the oil of the viscosity and tolerance recommended by the manufacturer for your motor. Filling a poor-quality product or product with incorrect characteristics can adversely affect the resource of the engine.
☑️ Oil replacement control
Diagnostics of chassis and steering
After several thousand kilometers on our roads, the suspension of the car is undergoing serious tests. In the first case, the mechanic must be careful. chassis. This includes visual inspection of levers, Silentblocks, ball supports and shock absorbers for damage, backlashes and underdrives.
Special attention is paid to steering. The absence of backlashes in the steering tips and rods, as well as the tightness of the rail, shall be checked. Any knocks or creaks that may have appeared during the run-in process should be fixed and eliminated. It often happens that after stretching the fasteners of the suspension, extraneous sounds disappear.
The condition of the tyres is also assessed as part of the inspection. The master must check:
- 🛞 Uniform wear of the tread (no "hernia" and uneven erasure).
- 💨 Tyre pressure and compliance with its recommendations on the gas tank hatch.
- 🔩 Reliability of fastening of wheel bolts and presence of all caps/secrets.
- ⚖️ If necessary, a recommendation for balancing the wheels.
If defects related to the quality of the assembly or materials are detected during the diagnosis, they are eliminated under warranty. That is why it is important to inform the master receiver about all the strangeness you notice in the behavior of the car on the road.
Checking of brake system and technical fluids
Traffic safety directly depends on the serviceability of the brake system. On TO-1, a visual inspection of brake pads and discs is carried out through special holes in calipers or by removing the wheels. The residual thickness of the friction linings and the condition of the disc surface for bullying or warping are assessed.
In addition, the level and condition of all technical fluids are checked. Unlike the oil in the engine, brake fluid Antifreezes change less often, but monitoring their level and density is mandatory. Brake fluid is hygroscopic and over time gains moisture, which can reduce its boiling point, although such a problem is rare in the first TO.
Table of the main liquids to be tested:
| Type of liquid | Regulatory level | Frequency of replacement (usually) | Signs of problems |
|---|---|---|---|
| Motor oil | Between MIN and MAX | 10,000 to $15,000. km | Blackening, smelling of burning |
| Coolant | Above the MIN mark | 40,000-60,000. km | Color change, flakes. |
| Brake fluid | The MAX mark. | 2 years / 60,000 km | Clouding, water at the bottom |
| GUR liquid | Between the marks | As of today | Foam, dark color |
In modern cars, the level of liquid in the tanks is often controlled electronically, but visual inspection by the master is a mandatory procedure of regulation. A low level may indicate hidden leaks that need to be fixed.
Ask the master to show you the oil probe after the drain – the color and smell will tell you more about the state of the engine than any words.
Electronic diagnostics and body inspection
The modern car is a complex computer complex. When passing TO-1, a diagnostic scanner is necessarily connected to the connector. OBD-II. The specialist reads error codes from all control units: engine, gearbox, ABS, ESP, airbags and climate control.
Even if the light bulb Check Engine The dashboard does not burn, and memory may contain "pending" errors that indicate unstable operation of sensors or systems. Timely detection of such failures prevents more serious breakdowns.
An external inspection of the body and salon is also carried out:
- 🚗 Checking the operation of all lighting devices (headlights, stop lights, turn signals).
- 🪟 Evaluation of the condition of glasses, mirrors and integrity of paint coating.
- 🔑 Check the operation of the central lock, windows and seat adjustments.
- 🧹 Inspection of the cabin for defects in finishing that have arisen during operation.
⚠️ Attention: If you find scratches or dents that are not your fault (for example, a paint defect or corrosion), fix it in the order-outfit TO-1. This will help to prove the guarantee case in the future.
What is node adaptation?
After some components or software are replaced, an adaptation procedure may be required. For example, a throttle or transmission should “learn” new parameters of operation. On TO-1, this is often done automatically when the scanner is connected.
Cost of work and additional recommendations
The price of the first maintenance consists of the cost of standard hours of work of masters and the price of consumables (oil, filters, gaskets). Official dealers may have higher prices than specialized services, but a visit to an authorized center is a prerequisite for the preservation of the property. guarantee.
It is necessary to be prepared for the fact that managers can offer additional paid services that are not included in the mandatory regulations. This can be anti-corrosion treatment, crankcase protection (if it is not in the base), engine washing or adding additives to fuel.
The decision to purchase such services should be taken in a balanced manner, based on real needs:
- Do you need additional protection if the warranty covers the main risks?
- Is it really necessary to wash if you are pouring quality oil?
- Does the cost of the extra services match their real value?
The main goal of TO-1 is not just a change of oil, but documentary confirmation of the serviceability of the car to preserve the warranty.
In conclusion, the first maintenance is a planned but important procedure. It allows you to make sure that the car is in good working order, and lay the foundation for its long and reliable service. Carefully examine the order-outfit before payment, make sure all work is done, and keep all checks and documents.
Is it possible to pass TO-1 not at the official dealer?
Technically, the law allows you to serve in any service that has a certificate of conformity. However, in practice, dealers often find reasons to refuse a warranty if the service book does not have their seal. To avoid disputes, the first TO is better to pass at the official representative of the brand.
How long does the first TA take?
On average, the procedure takes from 1.5 to 3 hours, depending on the load of the service and the model of the car. It is recommended to plan a visit to the service with a margin of time, as additional issues that require approval may be identified.
What happens if you miss TO-1?
Missing routine maintenance is the basis for removing the car from warranty accounting. In case of engine or transmission failure, repairs will have to be paid entirely out of pocket, which can cost hundreds of thousands of rubles.
Should I change the filter to TO-1?
This depends on the regulations of the specific manufacturer. Often the cabin filter is changed to TO-2 (after 30 thousand). km), but if you smell bad or airflow decreases, it can be replaced sooner, although it can be a paid service.
