Damaged tyres can cause tyre pressure loss.
As a result, you could lose control of your vehicle.
Check the wheels and tyres of your vehicle for damage regularly, i.e. at least every two weeks, as well as after driving off-road or on rough roads. Damaged wheels can lead to a loss of tyre pressure.
cuts in the tyres
punctures in the tyres
tears in the tyres
bulges on tyres
deformation or severe corrosion on wheels
Insufficient tyre tread will result in reduced tyre grip. The tyre tread is no longer able to dissipate water.
This means that in heavy rain or slush the risk of aquaplaning is increased, in particular where speed is not adapted to suit the conditions.
If the tyre pressure is too high or too low, tyres may exhibit different levels of wear at different locations on the tyre tread.
Summer tyres: 3 mm
M+S tyres: 4 mm

check the valve caps
Valves must be protected from moisture and dirt with valve caps specifically approved by Mercedes-Benz for your vehicle.
visually inspect the tread depth and the tyre tread across the whole tyre width
For summer tyres, the minimum tread depth is 3 mm and for winter tyres 4 mm.
If you have fitted snow chains to the front wheels, they may drag against the vehicle body or chassis components.
Vehicles with front-wheel drive: if you have fitted snow chains to the rear wheels, they may drag against the vehicle body or chassis components.
For safety reasons, Mercedes-Benz recommends that you only use snow chains that have been checked and approved. You can find further information on snow chains recommended for Mercedes-Benz in the wheel and tyre overview at Homepage Mercedes-Benz.
If you drive too fast with snow chains, they can break, injure other persons, and damage the vehicle.
If snow chains are fitted to steel wheels, the wheel trims can be damaged.
Snow chains are only permissible for certain wheel/tyre combinations. You can obtain information on them at a qualified specialist workshop.
For safety reasons, only use snow chains that have been specifically approved for your vehicle by Mercedes-Benz , or snow chains with the same quality standard.
The snow chains must be retightened after driving approximately 1 km. This is the only way to ensure the snow chains are optimally seated with clearance to adjacent components.
Vehicles with rear-wheel drive: only fit snow chains in pairs and only to the rear wheels. Observe the manufacturer's installation instructions.
Vehicles with front-wheel drive: only fit snow chains in pairs and only to the front wheels. Observe the manufacturer's installation instructions.
Use snow chains only when the road surface is completely snow-covered. Remove the snow chains as soon as possible when you come to a road that is not snow-covered.
Local regulations may restrict the use of snow chains. Observe the applicable regulations before fitting snow chains.
If snow chains are fitted, the maximum permissible speed is 50 km/h.
You can deactivate ESP® to pull away . This allows the wheels to spin, achieving an increased driving force.
Observe the notes on operating fluids More.
Windscreen washer concentrate is highly flammable. It could ignite if it comes into contact with hot engine component parts or the exhaust system.
Unsuitable windscreen washer fluids may damage the plastic surface of the exterior lighting.
Do not use distilled or de-ionised water. Otherwise, the fill level sensor may give a false reading.
Above freezing point: e.g. MB SummerFit
Below freezing point: e.g. MB WinterFit
For the correct mixing ratio, refer to the information on the anti-freeze container.
Mix the washer fluid with windscreen washer fluid all year round.
If you open the engine bonnet when the engine has overheated or during a fire in the engine compartment, you could come into contact with hot gases or other escaping operating fluids.
Components in the engine compartment may continue running or start up suddenly, even if the ignition is switched off.
Make sure of the following before performing tasks in the engine compartment:
Windscreen washer concentrate is highly flammable.
Certain component parts in the engine compartment can be very hot, e.g. the engine, the cooler and parts of the exhaust system.
bonnet
oil dipstick
engine oil filler opening cap
washer fluid reservoir cap
coolant expansion reservoir cap
Unsuitable windscreen washer fluids may damage the plastic surface of the exterior lighting.
Mix the washer fluid with windscreen washer concentrate all year round. Observe the additional information on windscreen washer fluid under "Operating fluids and capacities" More.
If the windscreen wipers begin to move while you are changing the wiper blades, you can be trapped by the wiper arm.
If the wiper arm on the windscreen or rear window is folded back before a wiper blade has been fitted, the window may be damaged by the force of the impact.
If the windscreen wipers have been folded back from the windscreen when the bonnet is opened, the windscreen wipers or the bonnet may be damaged.
If the colour of the maintenance display changes from black to yellow, the wiper blades should be replaced.
The time until the colour changes varies depending on the usage conditions.
If the tailpipe is blocked or sufficient ventilation is not possible, poisonous exhaust gases such as carbon monoxide may enter the vehicle. This is the case in enclosed spaces or if the vehicle gets stuck in snow, for example.
Flammable materials such as leaves, grass or twigs may ignite.
Operating the stationary heater or stationary ventilation drains the battery.
The fuel tank is filled above the reserve level.
The ignition is switched on.
Before setting your departure time, make sure that the clock on the on-board computer is set to the correct time. Otherwise, the auxiliary heating will switch on at the wrong time and possibly in an unsuitable location. When setting your departure time, you should also observe the notes on auxiliary heating.
Use the buttons on the steering wheel.
The display will show the current settings for the auxiliary heating.
If no departure time has been enabled, the display will show No preselection.
If a departure time has been enabled, the display will show its code letter, e.g. Departure time A, and the set departure time enabled.
The display will show the current settings in the Departure time list.
The display will show the code letter and the set departure time enabled.
The changed departure time will then be enabled. The display will show the relevant code letter along with the changed time.
