Driving and Driving Safety

d
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.
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.
d
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.
