Driving Programs for On-Road and
Off-Road DrivingTwo different driving programs with special power-
transmission and running-gear control systems
(such as ABS, off-road ABS and PSM, etc.) are pro-
vided in your Porsche, with the aim of realising the
best possible driving dynamics combined with
maximum safety.
All control systems meet these requirements for
both off-road and normal driving.With rocker switch A, you can easily select the ap-
propriate driving program to suit the special re-
quirements for the respective terrain.
Off-road program Low Range
(with reduction)
When Low Range is active, the power transmis-
sion and running-gear control systems are
automatically adapted to the requirements for
off-road driving.
On-road driving program High Range
(without reduction)
When High Range is active, the power-transmis-
sion and running-gear control systems are auto-
matically adapted to the requirements for on-road
driving.
UseRocker switch A is located in the center console
of the vehicle. It features a multi-step function and
can be operated in both directions. Each time the rocker switch is pushed forward,
the vehicle becomes one step more suitable for
off-road driving. This is realised by changing from
the on-road to the off-road driving program or by
engaging the differential locks in stages.
The number of differential locks that can be en-
gaged in Low Range depends on the equipment of
your vehicle.
Each time the rocker switch is pushed back, the
vehicle becomes one step more suitable for on-
road driving.
Once the driving program has been selected, the
rocker switch springs back to home position.
Notes on operation
If the Low Range indicator light beside the rocker
switch flashes rapidly after the ignition is
switched on, there is a fault in the shifting
system.
fPlease have the vehicle checked immediately
at an authorized Porsche dealer.

Engine Braking Support
(Assistance when heading downhill)The Porsche Down-Hill Assistant is an assistance
system which helps the driver at slower downhill
driving up to approx. 12 mph (20 km/h), e.g., on
steep slopes or on wintry mountain roads.
As long as the gas pedal is not used when trav-
eling downhill, the Porsche Down-Hill Assistant is
active and brakes the vehicle.
The braking ability of the Engine Braking Support
is affected by slippery surfaces (e.g., on icy or
loose surfaces), like all brakes.
If road grip is lost on one or more wheels, the
system brakes the wheels which have good road
contact.
Conditions:
– The gas pedal must not be used when
travelling downhill.
– The speed must not exceed 12 mph
(20 km/h).
– The selector lever position D or Mmust be
engaged.
Warning!
Risk of accident. Reduced braking ability on
a slippery surface.
fAlways adjust your driving style to the driving situation.
Tip on driving
The Porsche Down-Hill Assistant is active when
driving downhill either forwards or backwards.
Checks on test standsPower measurement
Power measurements on roller test stands are not
approved by Porsche.
Brake tests
Brake tests must be carried out only in High Range
and on plate-type test stands or roller test stands.
The following limit values must not be exceeded
on roller test stands:
– Testing speed 4.7 mph (7.5 km/h)
– Test duration 20 seconds
Parking brake test
Parking brake tests on the brake tester must be
performed only with the ignition switched off and
the selector lever in position N.
Balancing wheels on the vehicle
During finish balancing of the wheels, the entire ve-
hicle must be lifted and the wheels must be free to
turn.

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).
