Operation
Tires and wheels
!
When the wheels are heavily soiled,
e.g. after driving through mud, clean
the inside of the wheels with a jet of
water.

Life of tire

The service life of a tire is dependent upon
varying factors including but not limited to:
Driving style

!
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.

Direction of rotation

Unidirectional tires offer added advantag-
es, such as better hydroplaning perfor-
mance. To benefit, however, you must
make sure the tires rotate in the direction
specified.
An arrow on the sidewall indicates the
intended direction of rotation of the tire.

Checking tire inflation pressure

Warning!
If the tire pressure drops repeatedly:
Check the tires for punctures from
foreign objects.
Check to see whether air is leaking from
the valves or from around the rim.
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
correct the tire pressure if it is too low for
current operating conditions.
A table on the fuel filler flap lists the
specified tire inflation pressures for warm
and cold tires as well as for various
operating conditions.
