Damaged tyres can cause tyre pressure loss.
Insufficient tyre tread will result in reduced tyre grip.
The risk of aquaplaning is increased on wet roads, especially when the speed of the vehicle is not adapted to suit the conditions.
Summer tyres: 3 mm
M+S tyres: 4 mm
Check the tyre pressure More.
Visually inspect wheels and tyres for damage.
Check the valve caps.
Visual check of the tyre tread depth and the tyre contact surface across the entire width.
The minimum tread depth for summer tyres is 3 mm and for winter tyres 4 mm.
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.
If you fit snow chains to the front wheels of 4MATIC vehicles, you may damage components of the vehicle body or chassis.
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 Active Parking Assist when snow chains are fitted.
Vehicles with level control: if snow chains are fitted, only drive at raised vehicle level More.
Vehicles with rear axle steering: if snow chains are fitted, only drive with snow chain mode active More.
You can deactivate ESP® to pull away More. 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 be triggered erroneously.
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 washer fluid with windscreen washer fluid all year round.
You could come into contact with hot gases.
You could come into contact with other hot, 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:
Certain component parts in the engine compartment can be very hot, e.g. the engine, the cooler and parts of the exhaust system.
Windscreen washer concentrate is highly flammable. It could ignite if it comes into contact with hot engine component parts or the exhaust system.
If the windscreen wipers begin to move while you are changing the wiper blades, you can be trapped by the wiper arm.
The wiper arms will move into the replacement position.
When the colour of the maintenance display changes from black to yellow, the wiper blades should be replaced.
The duration 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 outside temperature is below 15 °C.
The fuel tank is sufficiently full.
If the fill level of the fuel tank is too low, the auxiliary heating mode may be restricted.
The red or blue indicator lamp on button will light up or go out.
Blue: stationary ventilation is switched on.
Red: the stationary heater is switched on.
Yellow: the departure time is preselected.
The stationary heater/ventilation will switch off automatically after 50 minutes.
Operation using the app: the stationary heater/ventilation can also be operated via the Mercedes me connect app. You can find further information in the separate Owner's Manual at Mercedes me connect Interactive Owner's Manual.
