Operation
Tires and wheels
Tire pressure changes by approximately 
1.5 psi (0.1 bar) per 18°F (10°C) of air 
temperature change. Keep this in mind 
when checking tire pressure where the 
temperature is different from the outside 
temperature. 
The tire temperature and with it the tire 
pressure is increased also while driving, 
depending on the driving speed and the 
tire load.
Check the spare tire periodically for condi-
tion and inflation. Spare tires will age and 
become worn over time even if never used, 
and thus should be inspected and replaced 
when necessary.
Rotating wheels
The wheels can be rotated every 3000 to 
6000 miles (5000 to 10000 km), or soon-
er if necessary, according to the degree of 
tire wear. The same direction of tire rota-
tion must be retained.
Rotate the wheels before the characteris-
tic tire wear pattern becomes visible 
(shoulder wear on front wheels and tread 
center wear on rear wheels).
Thoroughly clean the inner side of the 
wheels after each rotation. Check and en-
sure proper tire inflation pressure.
Warning!
G
Follow recommended inflation pressure.
Do not overinflate tires. Overinflated tires 
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes 
etc.
Do not underinflate tires. Underinflated tires 
wear unevenly, adversely affect handling 
and fuel economy, and are more likely to fail 
from being overheated.
Do not overload the tires by exceeding the 
specified vehicle capacity weight (as indicat-
ed by the label on the pillar in the driver’s 
door opening). Overloading the tires can 
overheat them, possibly causing a blowout.
Warning!
G
Rotate front and rear wheels only if they are 
of the same size.
Warning!
G
Have the tightening torque checked after 
changing a wheel. Wheels could become 
loose if not tightened with a torque of 
80 ft.lb. (110 Nm).
Use only genuine Mercedes-Benz wheel 
bolts specified for your vehicle's rims.
