Before driving off-road
Tyres

objects (e.g. stones) from the tread.

Rims
f Replace dented or damaged rims before
driving off-road.
Vehicles with SportDesign package
Warning!
Risk of damage.
On vehicles with the SportDesign package,
front, rear and side member trims are
painted.
Off-road driving can seriously damage these
trim parts.
f When driving off-road, make sure these parts
are not damaged.
f Make sure there is sufficient clearance
between obstacles and the underside of the
vehicle.
f Avoid driving through water.
f Do not use side member trims as a running
board.
After driving off-road
Off-road driving places a greater burden on the
vehicle than normal driving on roads.
f We recommend inspecting the vehicle after off-
road driving. Potential damage poses an
accident risk and impairs driving comfort.
Damage on the vehicle is recognised in good
time if the vehicle is checked.
Caution!
Vehicle damage poses an accident risk for
the vehicle occupants and other road users.
f In cases of doubt, have your vehicle checked
by a qualified specialist workshop.
f Examine tyres for signs of damage such as
cuts, tears, bulges or foreign objects stuck in
the tread and replace if necessary.
f Have any damage to your vehicle repaired
without delay.
Consult a qualified specialist workshop. We
recommend that you use a Porsche partner for
this work since these are staffed with trained
personnel and have the necessary parts and
tools.
