Observe the notes in the "Tyre pressure" section of the "Regular checking of the wheels and tyres" chapter null.
Set the correct tyre pressure for each axle on the vehicle.
If load-bearing index is comprised of two numbers, the first number before the "/" is for single tyres and the second number, after the "/", is for twin tyres.
Twin tyres null
For every 10 °C change in air temperature, the tyre pressure changes by approximately 30 to 40 kPa(0.3 to 0.4 bar/4.4 to 5.8 psi). Bear this temperature-related change in tyre pressure in mind when checking tyre pressures indoors, where the temperature may be higher than the outside temperature.
the room temperature is approximately 20 °C.
the outside temperature is approximately 0 °C.
set the tyre pressure to approximately 60 to 80 kPa(0.6 to 0.8 bar/8.7 to 11.6 psi) higher than that prescribed in the tyre pressure table.
For specific tasks, e.g. for winter services, a maximum permissible vehicle axle load for fitting approved attachments may be increased. In such cases, the speed of the vehicle is limited. The tyre pressure will then deviate from the information in the following tyre pressure table. It needs to be increased in accordance with the E.T.R.T.O. standard and the information provided by the tyre manufacturer.
Windscreen washer concentrate is highly flammable. It could ignite if it comes into contact with hot engine component parts or the exhaust system.
The washer fluid reservoir for the windscreen washer system and the headlamp cleaning system has a capacity of approximately nine litres.
If the washer fluid level in the washer fluid reservoir is too low, the on-board computer will display a grey event window containing the symbol.
A windscreen washer concentrate according to Mercedes-Benz Specifications for Service Products sheet no. 371.0 may be added to the washer fluid all year round. Adapt the mixing ratio to the outside temperature.
At temperatures above freezing, add a windscreen washer concentrate for the summer to prevent smearing. If there is a risk of frost, use a windscreen washer concentrate for winter to prevent the washer fluid from freezing on the windscreen.
If you are working on the wiper blades or wiper arms and using the steps and grab handles at the front of the vehicle, you may slip and/or fall.
If the windscreen wipers begin to move while you are changing the wiper blades, you can be trapped by the wiper arm.
Otherwise, the wiper blade could be damaged.
If the maintenance flap is opened while the wiper arms are folded out, it could be damaged.
If the wiper arms are folded back without wiper blades, the windscreen could be damaged.
Wiper blades are wear parts. Replace the wiper blades at least once a year. Otherwise, the windscreen will not be wiped properly.
check the oil level using the on-board computer null.
only use the engine oils specified in the section "Operating fluids" .
Use only oils approved for the vehicle and which meet the specified SAE classifications.
Only top up the oil filling capacity displayed on the on-board computer when the symbol appears in the menu window.
If the outside mirrors/camera arms are folded out or the windscreen wipers are switched on when using an automatic car wash, they may be damaged when using an automatic car wash.
Make sure that the outside mirrors or camera arms of the outside-mirror camera system are fully folded out again when you leave the automatic car wash.
If the vehicle is very dirty, wash off excess dirt before cleaning the vehicle in an automatic car wash.
After using an automatic car wash, wipe off the wax from the windscreen and the wiper rubbers. This will prevent smears and reduce wiping noises caused by residue on the windscreen.
