Regular checking of wheels and tyres

WARNING Risk of accident from damaged tyres

Damaged tyres can cause tyre pressure loss.

As a result, you could lose control of your vehicle.

Check the tyres regularly for signs of damage and replace any damaged tyres immediately.

WARNING Risk of aquaplaning due to insufficient tyre tread

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.

Thus, you should regularly check the tread depth and the condition of the tread across the entire width of all tyres.

Minimum tread depth for:

Summer tyres: 3 mm
M+S tyres: 4 mm

For safety reasons, replace the tyres before the legally prescribed limit for the minimum tread depth is reached.

Carry out the following checks on all wheels regularly, at least once a month or as required, e. g. prior to a long journey or driving off-road:

Check the tyre pressure More.
Visual inspection of wheels and tyres for damage.
Check the valve caps.
The valves must be protected against moisture and dirt by the valve caps approved especially for your vehicle by Mercedes-Benz.
Visual check of the tyre tread depth and the tyre tread condition across the entire width.
The minimum tread depth for summer tyres is 3 mm and for winter tyres 4 mm.

Notes on snow chains

WARNING Risk of accident due to incorrect snow chain fitting

If you have fitted snow chains to the front wheels, the snow chains may drag against the vehicle body or chassis components.

This could cause damage to the vehicle or the tyres.

Never fit snow chains on the front wheels.

Only fit snow chains on the rear wheels in pairs.

NOTEDamage to the wheel trim from fitted snow chains

If snow chains are fitted to steel wheels, the wheel trims can be damaged.

Remove the wheel trims of steel wheels before fitting snow chains.

Snow chains are only permissible for certain wheel/tyre combinations. You can obtain information about this from a Mercedes-Benz Service Centre.
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.
If snow chains are fitted, the maximum permissible speed is 50 km/h.
Vehicles with Active Parking Assist: do not use Parking Assist PARKTRONIC when snow chains have been fitted.
Vehicles with AIR BODY CONTROL: if snow chains are fitted, only drive at raised vehicle level .

You can permanently limit the maximum vehicle speed for driving with winter tyres More.

You can deactivate ESP® to pull away More. This allows the wheels to spin, achieving an increased driving force.

Notes on windscreen washer fluid

Observe the notes on operating fluids More.

WARNING ‑ Risk of fire and injury due to windscreen washer concentrate

Windscreen washer concentrate is highly flammable. It could ignite if it comes into contact with hot engine component parts or the exhaust system.

Make sure that no windscreen washer concentrate spills out next to the filler opening.

NOTEBlocked spray nozzles caused by mixing windscreen washer fluids

Do not mix MB SummerFit and MB WinterFit with other windscreen washer fluids.

Do not use distilled or de-ionised water as the fill level sensor may be triggered erroneously.

Recommended windscreen washer fluid:

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 antifreeze container.

Mix the washer fluid with the windscreen washer fluid all year round.

Topping up the windscreen washer system

WARNING Danger of burns from hot component parts in the engine compartment

Certain component parts in the engine compartment may be very hot, e.g. the engine, the radiator and parts of the exhaust system.

Let the engine cool down and only touch the component parts described below:

WARNING Danger of burns when opening the bonnet

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.

Before opening the bonnet, allow the engine to cool down.

In the event of a fire in the engine compartment, keep the engine bonnet closed and call the fire service.
