Determining tyre pressures

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.

Example: tyre size and load-bearing index
Read off tyre size and load-bearing index on the tyre.

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.

Example: permissible axle load
Determine permissible axle load by checking the vehicle identification plate null.
Select the tyre pressure table which corresponds to the tyre type.
  • Single tyres

  • Twin tyres null

Search tyre size in the tyre pressure table.
Search load-bearing index which corresponds to the tyre type next to the tyre size in the tyre pressure table.
Find maximum permissible axle load in the tyre pressure table and read off the tyre pressure.

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.

Example:
  • 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.

Topping up the windscreen washer system / headlamp cleaning system
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.
Topping up the washer fluid

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.

Pre-mix the washer fluid to the correct mixing ratio in a container.
Open the driver's door.
Remove the cap of the washer fluid reservoir.
Refill the washer fluid reservoir.
Press cap onto the filler opening of the washer fluid reservoir.
Close the driver's door.
Replacing the wiper blades
WARNING Risk of injury due to use of unsuitable climbing aids during wiper blade replacement

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.

When replacing the wiper blades, always use solid and stable climbing aids, e.g. a suitable ladder.
WARNING Risk of becoming trapped if the windscreen wipers are switched on while wiper blades are being replaced

If the windscreen wipers begin to move while you are changing the wiper blades, you can be trapped by the wiper arm.

Always switch off the windscreen wipers and ignition before changing the wiper blades.
NOTE Damage to the wiper blade
Touch the wiper blade only on the wiper arm.

Otherwise, the wiper blade could be damaged.

NOTE Damage to the maintenance flap or the windscreen

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.

Do not open the maintenance flap if a wiper arm is folded forward.
Do not fold the wiper arms back without the wiper blade.

Wiper blades are wear parts. Replace the wiper blades at least once a year. Otherwise, the windscreen will not be wiped properly.

Apply the parking brake.
Shift the transmission to the neutral position.
Switch off the engine.
Remove the key from the ignition lock.
To remove a wiper blade:
fold the wiper arm away from the windscreen.
Place the wiper blade in a perpendicular position.
Press the safety spring together and slide the wiper blade out of the bracket of the wiper arm in the direction of the arrow .
Remove the wiper blade .
To install a wiper blade:
slide the joint piece of the wiper blade into the bracket of the wiper arm in the direction of the arrow .
Press the wiper blade into the bracket of the wiper arm until the safety spring engages audibly.
Rotate the wiper blade parallel to the wiper arm .
Fold the wiper arm back onto the windscreen.
Topping up the engine oil
Requirements:
  • check the oil level using the on-board computer null.

  • only use the engine oils specified in the section "Operating fluids" .

NOTE Engine damage caused by driving with excess engine oil
Avoid long journeys with excess engine oil.

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.

Park the vehicle horizontally.
Apply the parking brake.
Switch off the engine.
Open the maintenance flap null.
Unscrew the cap and remove it.
Top up the oil filling capacity displayed on the on-board computer.
Put on the cap and screw it closed.
Close the maintenance flap.
Notes on using automatic car washes
NOTE Damage when using an automatic car wash

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.

Before using automatic car washes:
switch off the windscreen wipers
vehicles with outside mirrors: fold in the outside mirrors
vehicles with outside-mirror camera: fold in the camera arms

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.
