A car roof rack has long ceased to be just a utilitarian device for transporting bulky cargo, but has become an important element of driving comfort and safety. Modern car boxes, including popular models of the series Lux, allow you to significantly expand the useful volume of the vehicle without sacrificing the interior space of the cabin. This is especially true for family trips, when every centimeter in the cabin counts, and you need to take a lot of things with you.
Car owners often face a dilemma: leave the car as is or invest in additional equipment that may only be used a couple of times a year. However, those who have at least once traveled with a properly selected roof system can no longer imagine life without it. Autobox Lux stands out on the market with its design and thoughtful ergonomics, which makes it one of the leaders in its class.
In this article we will analyze in detail the technical nuances, features of installation and operation of boxes of this line. You will learn how not to make a mistake when choosing a volume, what subtleties there are when attaching to roof rails, and how to avoid common mistakes during operation. The right approach to choosing roof accessories is the key to your safety on the road.
Key benefits and design features of Lux
The range of car boxes under the Lux brand was developed taking into account modern requirements of aerodynamics and aesthetics. Unlike the bulky “boxes” of the past, modern boxes have a streamlined shape, which minimizes air resistance and, as a result, reduces fuel consumption and noise levels. Using high quality ABS plastic ensures impact resistance and resistance to ultraviolet radiation.
One of the main features is the lid opening system. Depending on the specific modification, the mechanism can operate on one or both sides, which greatly simplifies access to things in the parking lot. Reliable gas shock absorbers secure the lid in the open position, eliminating the risk of sudden slamming. This is especially convenient in windy weather or when the user is short.
When choosing the color of a car box, try to match the tone of the body or, conversely, play with contrast - black matte Lux boxes look great on light-colored cars, creating a sporty look.
It is important to note the quality of the seals. Rubber profiles around the perimeter of the lid ensure the tightness of the internal space, protecting the contents from rain, snow and road dust. Even when washing a car under high pressure, moisture should not penetrate inside if the seals are in good condition and the lid is closed until it clicks.
How to choose the right volume and dimensions of the box
Choosing the right volume is not simply a matter of “the more, the better.” It is necessary to take into account the load-carrying capacity of the roof of your car, as well as the geometric parameters of the body itself. A box that is too long can prevent the fifth door or trunk from opening normally, which will create serious inconvenience in operation.
When selecting a model, focus on typical usage scenarios. To transport skis, snowboards or fishing rods, narrow and long models are sufficient. If you plan to load soft bags, backpacks and suitcases, it is better to consider options with greater width and height. The maximum length of skis compatible with a specific model is always indicated in the technical data sheet of the product.
It is also worth paying attention to the height of the box profile. Low models look more elegant and have less impact on the car's center of gravity, but they are more difficult to accommodate bulky items. High boxes are more spacious, but may limit passage under low arches or entry into some underground parking lots.
Step-by-step instructions for installing an autobox
Installing a roof rack is a procedure that does not require complex tools, but requires care and adherence to a sequence of actions. Improper installation can result in damage to the vehicle's roof or, worse, loss of cargo at high speed. Before starting work, carefully read the instructions supplied with the kit.
The installation process begins with surface preparation. The roof of the car and the lower part of the box must be clean and dry. Dirt or sand caught between the mounts and the body can become abrasive and scratch the paintwork when vibrated. Install the box in the center of the roof, aligning it with the side edges.
☑️ Pre-departure checklist
Next comes the fixation stage. Most Lux models are equipped with a quick clamp system or screw fastening. If a screw mechanism is used, tighten the nuts evenly from one fastener to another to avoid distortion. The final effort should be significant, but without fanaticism, so as not to break the thread.
⚠️ Attention: After the first 50 kilometers, be sure to stop and check all fasteners. Plastic and metal have different coefficients of thermal expansion, and the initial tightening may become loose.
Comparison table of popular models
To simplify the selection process, we have prepared a comparison of the main characteristics of the most popular modifications. The differences concern not only the volume, but also the type of fastening, as well as compatibility with various types of arches (round, aerodynamic, square).
| Model | Volume (liters) | Length(cm) | Mounting type | Load capacity (kg) |
|---|---|---|---|---|
| Lux Sport 350 | 350 | 175 | Quick clamp | 50 |
| Lux Family 450 | 450 | 195 | Screw (T-bolt) | 75 |
| Lux Touring 500 | 500 | 210 | Universal | 75 |
| Lux Compact 300 | 300 | 160 | Quick clamp | 50 |
When analyzing the table, it is worth considering that the declared load capacity refers to the box itself, but the actual load is limited by the characteristics of the roof of your car. Load capacity the roof rarely exceeds 75-100 kg, including the weight of the trunk itself and the arches. Exceeding this limit is dangerous due to deformation of the roof and deterioration in controllability.
Rules for safe operation and driving
The presence of cargo on the roof radically changes the behavior of the car on the road. The center of gravity shifts, the windage increases, and the aerodynamics change. The driver must adapt his driving style: avoid sudden lane changes, slow down before turns and increase the distance to the vehicle in front.
Particular attention should be paid to the speed limit. Manufacturers of car boxes, as a rule, do not recommend speeding 130 km/h, and when fully loaded, it is better to reduce this limit to 110-120 km/h. High speed creates powerful air currents that can rip off a loose cover or create dangerous vibrations.
Effect on fuel consumption
Installing a full autobox can increase fuel consumption by 10-15% when driving on the highway due to increased aerodynamic drag. An empty box also increases consumption, but to a lesser extent (about 5%).
During the winter period of operation, it is important to monitor the condition of the locks. The mechanisms can freeze, so it is recommended to periodically treat them with silicone grease or defrost. Trying to open a frozen lock by force can lead to damage to the key or internal mechanisms.
⚠️ Attention: Never leave the car box open while driving, even for a short distance. An open lid creates enormous resistance and can be instantly torn off by a stream of air, damaging the roof or glass.
Caring for your car box and extending its service life
The Lux car box, like any other element of the car’s external equipment, requires regular maintenance. Dirt, road chemicals and bird droppings can degrade the structure of plastic and dull its color over time. Regular washing with warm water and mild car shampoos will help maintain a presentable appearance.
Do not use aggressive chemicals, abrasive sponges or brushes with hard bristles - they will leave micro-scratches that will quickly become clogged with dirt. To protect the surface, you can use special plastic polishes or wax compounds that create a hydrophobic layer.
In the off-season, when the box is not in use, it is better to dismantle it and put it in a dry, cool place. Storage in direct sunlight or at extremely low temperatures may cause plastic geometry to change or seals to lose elasticity.
Regular lubrication of hinges and locks with silicone is the simplest procedure that will prevent 90% of problems with opening the box in winter.
Frequently asked questions (FAQ)
Is it possible to wash a car in an automatic car wash with a car wash box installed?
Most modern automatic car washes (portal and tunnel) allow vehicles with roof racks to pass through, as long as the car's height does not exceed the wash limits (usually up to 2.2–2.5 meters). However, it is recommended to select the “no brushes” or “chemicals/water only” washing mode, since the rotating brushes can catch the protruding parts of the box.
What to do if the car box key is lost?
Lux boxes usually come with several keys. If all of them are lost, do not try to open the lock by force - you will damage the mechanism. Contact the manufacturer or authorized dealer with the lock code (usually found on the tag or in the documentation). You can make a duplicate using the code.
Does the autobox affect the noise in the cabin?
When installed correctly and at speeds up to 110-120 km/h, a high-quality aerodynamic box creates virtually no noise. A whistling or humming noise may occur if the box is installed out of position, if the seals are damaged, or if the travel speed exceeds the recommended speed.
Is it possible to transport dangerous goods in a box?
It is strictly forbidden to transport flammable liquids (gasoline in cans), gas in cylinders or items that emit a strong odor in sealed car boxes. In a confined space, vapors can accumulate, creating an explosive situation or poisoning if opened.
