Driving instructions
Tires
ț Check the tread depth and maintain
specified tire inflation pressure
(a placard with the recommended tire
inflation pressures is located on the
driver’s door B-pillar (
୴ page 388)).
ț Check tires for possible damage and
remove foreign objects.
ț Replace missing valve caps.
Rims
ț Dented or bent rims can cause tire in-
flation pressure loss and damage the
tire beads. For this reason, check and,
if necessary, change rims before driv-
ing off-road.
Vehicle tool kit
ț Check if the vehicle jack ( ୴ page 492)
is functional.
ț In all cases take the vehicle tool kit, a
strong tow rope, a shovel and a small
plank (to put under the vehicle jack on
sandy soil) with you.
