Operation
Tires and wheels
Life of tire
The service life of a tire is dependent upon 
varying factors including but not limited to:
Driving style
Tire pressure
Distance driven
Direction of rotation
Unidirectional tires offer added advantag-
es, such as better hydroplaning perfor-
mance. To benefit, however, you must 
ensure that the tires rotate in the direction 
specified.
An arrow on the sidewall indicates the in-
tended direction of rotation of the tire.
Checking tire inflation pressure
Correct the tire pressure only when tires 
are cold.
Regularly check your tire pressure at inter-
vals of no more than 14 days.
If the tires are warm, you should only cor-
rect the tire pressure if it is too low for cur-
rent operating conditions.
A table on the fuel filler flap lists the spec-
ified tire inflation pressures for warm and 
cold tires as well as for various operating 
conditions.
!
When the wheels are heavily soiled, 
e.g. after driving through mud, clean 
the inside of the wheels with a jet of 
water.
Warning!
G
Tires and spare tire should be replaced after 
six years, regardless of the remaining tread.
!
Keep unmounted tires in a cool, dry 
place with as little exposure to light as 
possible. Protect tires from contact 
with oil, grease and gasoline.
Warning!
G
If the tire pressure drops repeatedly:
Check the tires for punctures from for-
eign objects.
Check to see whether air is leaking from 
the valves or from around the rim.
