order to inspect the inner side of the tyre

All wheels must have a valve cap to protect
R
the valve against dirt and moisture. Do not
fit anything onto the valve (such as tyre
pressure monitoring systems) other than
the standard valve cap or other valve caps
approved by Mercedes-Benz for your vehi-
cle.
Regularly check the pressure of all the tyres

including the emergency spare wheel or the
spare wheel, particularly prior to long trips,
and correct the pressure as necessary
( page 243).

Risk of accident
Bear in mind that:
tyre grip decreases rapidly on wet roads
R
when the tread depth is less than 3 mm.
Thus, you should replace tyres that have
insufficient tread.
winter tyres should be replaced when the
R
tread depth is 4 mm or less as they no lon-
ger provide adequate grip.
the tread on a tyre may not wear evenly.
R
Thus, you should regularly check the tread
depth and the condition of the tread across
the entire width of all tyres. If necessary,
turn the front wheels to full lock in order to
inspect the tyre tread more easily.
Otherwise, you could lose control of the vehi-
cle and cause an accident due to the reduced
grip of the tyres on the road.

Storing tyres

Store tyres that are not being used in a cool,
dry and preferably dark place. Protect the
tyres against oil, grease, petrol and diesel.
Cleaning tyres
G Risk of accident
Do not use high-pressure cleaners with circu-
lar-jet nozzles (dirt grinders) to clean your
vehicle, in particular the tyres. You could oth-
erwise damage the tyres and cause an acci-
dent.

Tyre pressure

Recommended tyre pressure
You will find a table of tyre pressures for var-
ious operating conditions on the inside of
your vehicle's fuel filler flap.
The applicable value for the emergency spare
wheel is stated on the spare wheel and in the
technical data section.
For trailer towing, adjust the tyre pressure of
the rear tyres to the maximum tyre pressure
value stated on the table inside the fuel filler
flap.
The load conditions "partially laden" and "fully
laden" are defined in the table for different
numbers of passengers and amounts of lug-
gage. The actual number of seats may vary –
for more information please refer to the vehi-
cle's registration documents.
If no other data is stated, the tyre pressures
specified on the fuel filler flap apply for all
tyres approved for this vehicle.
