Tips on driving
fAvoid high engine speeds (max. 2,500 rpm).
fDo not perform manual gear changes when
driving, and try to avoid stopping.
Moving off in the water can be difficult due to
the high resistance and the loose surface in-
volved.
fStart the water crossing at a shallow place at
walking speed.
fAfter checking the body of water, take the
shortest path through it.
fNever drive into the water at high speed. The
resulting “bow wave” could damage the engine
and its accessories.
fAdjust your driving style to the unfamiliar sur-
roundings.
fCross the body of water slowly and at a con-
stant speed.
fNever turn around when crossing a body of wa-
ter.
fIf it is not possible to cross the body of water,
the car must be backed out of it in reverse
gear.
The servo pump and alternator can fail if the car is
driven through water for an extended period.
fIf the servo pump fails, substantially more
force will have to be exerted in order to steer. Maintenance note
The car requires a special check after the water
crossing.
fRemove mud from the tire tread.
fBriefly apply the brakes in order to dry them af-
ter driving through the water.
ObstaclesfPlease observe the chapter “GROUND CLEA-
RANCE” on Page 390.
Note on operation
fActivate Low Range and engage differential
locks if necessary.
Tips on driving
fJust before reaching the obstacle, ease off the
accelerator slightly and use the car's momen-
tum to cross the obstacle. This will prevent the
car from jumping over the obstacle and landing
on the following downward slope at an exces-
sive speed.
fAvoid high engine speeds (max. 2,500 rpm).

Crossing obstacles
Caution!
Risk of damage to the underbody and chas-
sis components if obstacles are traversed
improperly.
fAlways bear in mind the ground clearance of
your vehicle.
fSlowly drive over the middle of tree trunks,
boulders or other obstacles with one of the
front wheels.
fCross the obstacle with the rear wheel in the same way.
Note on operation
fActivate Low Range and engage differential
locks if necessary.Tips on driving
fHave your passenger direct you if necessary.
fAvoid high engine speeds (max. 2,500 rpm).
fDrive slowly.
Driving on sandNote on operation
fActivate Low Range and engage differential
locks if necessary.
Tips on driving
Loose sand is an especially tricky surface for off-
road driving.
You can often become stuck in sand within
minutes if you do not drive correctly in such
situations.
fDrive at brisk pace and do not stop under any
circumstances. This will reduce the chance of
the car becoming bogged down.
fFollow existing tracks – provided that they
have not been covered by blown sand, are not
too deep and the car's ground clearance is
sufficient.
Please observe the chapter “GROUND CLEA-
RANCE” on Page 390.
fAvoid high engine speeds (max. 2,500 rpm).

When driving on slopes with soft sand on vehicles
with Tiptronic S:
fUse the manual select mode M in addition to
the Low Range program.
If your vehicle becomes stuck nevertheless:
Do not spin the wheels. Instead, use branches,
mats or similar items to provide adequate traction
so that you can drive out of the critical area.
Track rutsOther vehicles leave ruts in many off-road courses
or gravel roads.
fPlease observe the chapter “GROUND CLEA-
RANCE” on Page 390.
Caution!
Risk of damage to the vehicle floor when
driving through ruts that are too deep.
fAlways bear in mind the car's ground clear-
ance.
fDo not drive over ruts that are too deep.
Note on operation
fActivate Low Range and engage differential
locks if necessary.
Tips on driving
fIn cases of doubt, drive with one wheel on the
strip of grass between the ruts.
fAvoid high engine speeds (max. 2,500 rpm).
fDrive slowly.

Air Suspension with Level Control
and Height AdjustmentOn vehicles with air suspension, the driver can set
five different level steps manually.
The preselected level is automatically adjusted to
suit the vehicle speed.
The height of the car is automatically kept
constant when the car is loaded.
Tip on driving
It is not permissible to drive on public roads with
the car in the terrain or special terrain setting.Note on operation
Frequent level changes can cause the compressor
to overheat. In this case, the compressor must
cool for several minutes before the level adjust-
ment is fully functional again.
Normal levelThe ground clearance at normal level is around
8.5 in. (217 mm).Terrain levelThis setting is intended for off-road driving, field
paths and forest paths, etc.
The vehicle is raised by around 1 in. (26 mm) com-
pared to normal level.
Terrain level can be selected only manually at
speeds below around 50 mph (80 km/h).
The car is automatically lowered to normal level at
speeds exeeding around 50 mph (80 km/h).
The car is automatically raised to terrain level
when Low Range is activated.This setting is intended only for extremely chal-
lenging terrain requiring maximum ground clear-
ance. The vehicle is raised by 2.2 in. (56 mm)
compared to normal level.
The warning light in the instrument panel comes
on when the special terrain level has been
reached.
Special terrain level can be selected only at
speeds below around 19 mph (30 km/h).
The car is automatically lowered to terrain level at
speeds exeeding around 19 mph (30 km/h).
Low levelThis level is intended for high-speed driving. Above
speeds of around 78 mph (125 km/h), the car is
lowered by around 1 in. (27 mm) compared to nor-
mal level.
When the speed drops to below around 25 mph
(40 km/h), the car is automatically raised to nor-
mal level.Special low levelAt extremely high speeds, for example when oper-
ated on a race track, the car is lowered 0.4 in.
(11 mm) compared to the low level.

Loading level
Caution!
Risk of damage to running-gear parts, units
and the vehicle underbody.
If the car is driven off a curb when at loading level,
for example, insufficent ground clearance can
cause it to bottom out.
fAlways switch to normal level before moving off.
This setting makes it easier for you to load the lug-
gage compartment.
The vehicle is lowered by around 2.4 in. (60 mm)
compared to normal level.
The car is automatically raised to normal level at
speeds exceeding around 3 mph (5 km/h).

Exercise Extreme Caution when
Working on your Vehicle
Danger!
Ignoring the following instructions may
cause serious personal injury or death.
fThe engine compartment of any motor vehicle
is a potentially hazardous area. If you are not
fully familiar with proper repair procedures, do
not attempt the adjustments described on the
following pages.
This caution applies to the entire vehicle.
fO n l y w o r k o n y o u r v e h i c l e o u t d o o r s o r i n a w e l l
ventilated area.
fEnsure that there are no open flames in the
area of your vehicle at any time when fuel
fumes might be present. Be especially cau-
tious of such devices such as hot water heat-
ers which ignite a flame intermittently.
fBefore working on any part in the engine com-
partment, turn the engine off and let it cool
down sufficiently. Hot engine compartment
components can burn skin on contact.
fBe alert and cautious around engine at all
times while the engine is running.
If you have to work on the engine while it is run-
ning, always put the handbrake on and put the
gearshift lever in neutral or the selector lever
in position P.fIn particular, be very careful to ensure that
items of clothing (ties, shirt, sleeves etc.), jew-
elry, long hair, hand or fingers cannot get
caught in the fan, belts or other moving parts.
The radiator and radiator fans are in the front
of the car.
The fans can start or continue running as a
function of temperature, even with the engine
switched off.
Carry out work in these areas only with the en-
gine off and exercise extreme caution.
fYour Porsche is equipped with an electronic ig-
nition system. When the ignition is on, high volt-
age is present in all wires connected with the
ignition system; therefore, exercise extreme
caution when working on any part of the engine
while the ignition is on or the engine is running.
fAlways support your car with safety stands if it
is necessary to work under the car. The jack
supplied with the car is not adequate for this
purpose.
For vehicles with air suspension with level con-
trol and height adjustment switch off level con-
trol. Therefore:
Please observe the chapter “RAISING VEHICLE
WITH THE JACK” on Page 256.
fWhen working under the car without safety
stands but with the wheels on the ground,
make sure the car is on level ground, the
wheels are blocked, and that the engine can-
not be started.
Withdraw ignition keys (switch ignition off in ve-
hicles that have Porsche Entry & Drive).fDo not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher in close reach.
fIncomplete or improper servicing may cause
problems in the operation of the car. If in doubt
about any servicing, have it done by your au-
thorized Porsche dealer.
Improper maintenance during the warranty pe-
riod may affect your Porsche warranty cover-
age.
fSupplies of fluids, e.g. engine oil, washer fluid,
brake fluid or coolant, are hazardous to your
health.
Keep these fluids out of children's reach and
dispose of them in accordance with the appro-
priate regulations.
fSome countries require additional tools and
special spare parts to be carried.
Please make enquiries before driving abroad.
