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

After driving off road
Off-road driving places a greater burden on the ve-
hicle than does 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
car is recognised in good time if the car is
checked.
Warning!
Car damage poses an accident risk for the
vehicle occupants and other road users.
f In cases of doubt, have your vehicle checked
by your authorized Porsche dealer.
f Examine tires for signs of damage such as
cuts, tears, bulges or foreign objects stuck in
the tread. Replace a damaged tire if necessa-
ry.
f
Have any damage to your vehicle repaired by
an authorized Porsche dealer without delay.
Recommended procedure
f Deactivate Low Range.
f Clean headlights and tail lights and check them
for signs of damage.
f Clean the front and rear licence plates.
f Clean the tire tread with a jet of water and re-
move any foreign objects.
f Clean wheels, wheel housings and the under-
body with a jet of water.
f Check whether the car has picked up plant
parts or branches.
These materials increase the risk of fire and
can damage fuel lines, brake hoses, boots of
the axle joints and drive shafts.
f
After off-road driving, always check the entire
floor assembly, tires, body structure, steering
system, running gear and exhaust system for
signs of damage.
f After driving for an extended period through
mud, sand, water or substances with a similar
soiling effect, check the brake discs, brake
pads, wheels and axle joints and have them
cleaned.
f If you experience severe vibrations after
driving off road, check the wheels for foreign
substances.
These substances can produce an imbalance
which might be responsible for the vibrations.
Removing these deposits may remedy the
problem.
