California Proposition 65 Warning
Warning!
Engine exhaust, some of its constituents, and
certain vehicle components contain or emit chemi-
cals known to the State of California to cause
cancer and birth defects or other reproductive
harm.
In addition, certain fluids contained in vehicles and
certain products of component wear contain or
emit chemicals known to the State of California to
cause cancer and birth defects or other reproduc-
tive harm.Hot Exhaust Pipes
Warning!
Risk of burn injury when standing near or
coming into contact with the exhaust pipe.
The exhaust pipe is hot when the vehicle is running
and remains hot for some time after the vehicle is
turned off.
fTo prevent injury, make a point of noting where
your vehicle’s exhaust pipe is, avoid placing
your legs near the exhaust pipe when loading
and unloading cargo in the rear, and closely
supervise children around the vehicle during
time when the exhaust pipe could be hot. A hot exhaust pipe can cause serious burns.
Portable Fuel Containers
Danger!
Portable fuel containers may leak, whether
they are full or partially empty. Fuel leaking
from a portable container carried in your
vehicle could, in case of an accident, cause
a fire or explosion, resulting in serious
personal injury or death.
fNever carry additional fuel in portable contai-ners in your vehicle.
Vehicles with SportDesign package
Caution!
Risk of damage. On vehicles with Sport-
Design package, front, rear, and side
member trim are painted and located lower
on the vehicle. Off-road driving can seriously
damage these trim parts.
fWhen driving off-road, make sure these parts
are not damaged.
fMake sure there is sufficient clearance
between obstacles and the underside of the
vehicle.
fAvoid driving through water.
fDo not use side member trim as a running board.
Porsche Ceramic Composite Brake
(PCCB)fPlease see the chapter “BRAKES” on
Page 163.
The high-performance brake system is designed
for optimal braking effect at all speeds and tempe-
ratures.
Certain speeds, braking forces and ambient condi-
tions (such as temperature and humidity) therefore
might cause brake noises.
Wear on the different components and braking
system, such as brake pads and brake discs,
depends to a great extent on the individual driving
style and the conditions of use and therefore
cannot be expressed in actual miles on the road.
The values communicated by Porsche are based
on normal operation adapted to traffic. Wear incre-
ases considerably when the vehicle is driven on
race tracks or through an aggressive driving style.
fPlease consult an authorized Porsche dealer
about the current guidelines in effect before
such use of your vehicle.

6Break in hints for the first
2,000 miles (3,000 kilometers)The following tips will be helpful in obtaining
optimum performance from your new Porsche.
Despite the most modern, high-precision manufac-
turing methods, the moving parts must still wear
in with each other. This wearing-in occurs mainly in
the first 2,000 miles (3,000 km).Therefore:fPreferably take longer trips.
fAvoid frequent cold starts with short-distance
driving whenever possible.
fAvoid full throttle starts and abrupt stops.
fDo not exceed maximum engine speed of
4,200 rpm (revolutions per minute).
fDo not run a cold engine at high rpm either in
Neutral or in gear.
fDo not let the engine labor, especially when
driving uphill. Shift to the next lower gear in
time (use the most favorable rpm range).
fNever lug the engine in high gear at low
speeds. This rule applies at all times, not just
during the break-in period.fDo not participate in motor racing events,
sports driving schools, etc. during the first
2,000 miles (3,000 kilometers).
There may be a slight stiffness in the steering,
gear-shifting or other controls during the break-in
period which will gradually disappear.
Break in brake pads and brake discsNew brake pads and discs have to be “broken in”,
and therefore only attain optimal friction when the
car has covered several hundred miles or km.
The slightly reduced braking ability must be
compensated for by pressing the brake pedal
harder. This also applies whenever the brake pads
and brake discs are replaced.New tiresNew tires do not have maximum traction. They
tend to be slippery.
fBreak in new tires by driving at moderate
speeds during the first 60 to 120 miles (100
to 200 km). Longer braking distances must be
anticipated.
Engine oil and fuel consumptionDuring the break-in period oil and fuel consump-
tion may be higher than normal.
fPlease see the chapter “ENGINE DATA” on
Page 349.
As always, the rate of oil consumption depends on
the quality and viscosity of oil, the speed at which
the engine is operated, the climate and road
conditions, as well as the amount of dilution and
oxidation of the lubricant.
fMake a habit of checking engine oil with every
refueling, add if necessary.

Brake boosterThe brake booster assists braking only when
the engine is running.
When the car is moving while the engine is not
running, or if the brake booster is defective, more
pressure on the brake pedal is required to bring
the car to a stop.
Moisture, road salt or grit on brakes affects
braking.
Brakes will dry after a few cautious brake applica-
tions.
Warning!
Risk of an accident, resulting in serious per-
sonal injury or death.
Driving through water may reduce the trac-
tion. Moisture on brakes from road water, car
wash, or a coating of road salt or grit may
affect braking efficiency.
fCautiously apply brakes to test brakes after exposure to road water, etc.
Brake wearYour car has excellent brakes, but they are still
subject to wear. The rate at which they wear
depends on how the brakes are used.
fHave the brake system inspected at the inter-
vals recommended in your Maintenance Book-
let.
Brake system warning light
You can check the functionality of the brake sys-
tem warning light by switching the ignition to the
“On” position and verifying that the warning light
illuminates.
A warning message will be displayed on the multi-
purpose display of the instrument panel if the
brake pads are worn, excessively.
fDo not continue to operate the vehicle.
Have your authorized Porsche dealer inspect
or replace the brake pads.
fPlease see the chapter “OVERVIEW OF
WARNING MESSAGES” on Page 149.
Brake pads and brake discsWear on the brake pads and brake discs depends
to a great extent on the driving style and the con-
ditions of use and therefore cannot be expressed
in actual miles on the road.
The high-performance brake system is designed
for optimal braking effect at all speeds and tem-
peratures.
Certain speeds, braking forces and ambient
conditions (such as temperature and humidity)
therefore might cause the brakes to squeal.

Driving and Driving Safety New brake pads or linings
New brake pads have to be “broken in”, and there-
fore only attain optimal friction when the car has
covered several hundred miles or km.
The slightly reduced braking ability must be com-
pensated for by pressing the brake pedal harder.
This also applies whenever the brake pads and
brake discs are replaced.
Warning!
fDo not obstruct the pedal travel with floor mats
or other objects.
The brake booster is ready for operation only
while the engine is running.
If the engine is switched off or there is a defect in
the brake booster, much greater force has to be
applied to the pedal when braking.
fPlease see the chapter “TOWING” on
Page 342.
In heavy rain, while driving through water or after
leaving a car wash, the braking action may be
delayed and increased pressure may be required.
fFor this reason, keep further back from the ve-
hicle in front and “dry” the brakes by applying
them at intervals. Make sure that following traf-
fic is not affected.
After a long drive over salted or sanded roads, a
coating may form on the brake discs and pads
that significantly reduces friction and thus braking
action.fEven though the brake discs consist of alloyed
grey cast iron, they will unavoidably start to
corrode if your car is parked for an extended
period. The brakes will tend to “rub” as a
result.
The nature, extent and effects of corrosion
depend on the amount of time the vehicle was
parked, whether road salt or grit was spread
and whether grease-dissolving agents were
used in car washes (not on vehicles with
Porsche Ceramic Composite Brake).
To prevent corrosion of the brake discs, “brake
them dry” before parking the car (not on
vehicles with Porsche Ceramic Composite
Brake).
If the braking comfort is noticeably impaired,
we recommend having the brake system
checked by experts at an authorized Porsche
dealer.
fTo relieve the braking system on downhill
stretches, change down to a lower gear in
enough time to obtain engine braking.
If engine braking is insufficient on steep
stretches, operate the footbrake at intervals.
Continuous braking overheats the brakes and
reduces the braking effect.
fPlease see the chapter “BRAKE-FLUID LEVEL”
on Page 257.

Driving and Driving Safety The events below inform the driver of PSM control
operations and warn him to adapt her/his driving
style to the road conditions:
– The multi-functional information light in the
instrument panel lights up.
– Light in the PSM Off button flashes.
– Hydraulic noises can be heard.
– The vehicle decelerates and steering-wheel
forces are altered as the PSM controls the
brakes.
– Reduced engine power.
– The brake pedal pulsates and its position is
changed during braking.
In order to achieve full vehicle deceleration,
foot pressure must be increased after begin-
ning of the brake pedal pulsing.
Examples of PSM control operations
– If the front wheels of the vehicle drift on a
corner, engine power is reduced and the rear
wheel on the inside of the corner is braked if
necessary.
– If the rear of the vehicle swings out on a
corner, the front wheel on the outside of the
corner is braked.– Brake system prefilling:
The brake system is prepared for possible sub-
sequent emergency braking if the accelerator
pedal is released suddenly and quickly.
The brake system is prefilled and the brake
pads are already applied gently to the brake
discs.
– Brake booster:
In the event of an emergency braking operation
where the pedal force is insufficient, a brake
booster provides the braking pressure neces-
sary for maximum deceleration at all 4 wheels.
Combined use of PSM and PTM/PTM Plus
In order to ensure optimal stabilization of the ve-
hicle, the center differential lock (PTM) and possib-
ly the rear differential lock (PTM Plus) are also
opened when PSM interventions occur.
Tip on driving
When PSM is switched off, wheel-specific brake in-
terventions and the traction control system (TCS)
are also inactive.
The automatic brake differential (ABD) remains on.Off-road PSM
(PSM in Low Range program)
When Low Range is active, an off-road PSM
specially matched to off-road driving is activated
to enhance traction.
In order to improve driveability on difficult terrain,
the response of the off-road PSM is less sensitive
in the low speed range when the vehicle is opera-
ted in the Low Range off-road driving program.
If the brakes are highly stressed, the automatic
brake differential (ABD) switches itself off to
protect the brakes. It remains deactivated until the
brake system has cooled sufficiently.
Engine drag torque control
In conditions of excessive slip, the engine drag
torque control system prevents all driven wheels
from locking up when the car is passing. This is
also the case for downshifts on a slippery road.

Driving and Driving Safety
197
Recommended procedure
fDeactivate the Low Range off-road driving
program.
fClean headlights and tail lights and check them
for signs of damage.
fClean the front and rear lincense plates.
fClean the tire tread with a jet of water and
remove any foreign objects.
fClean wheels, wheel housings and the under-
body with a jet of water.
fCheck 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.
fAfter off-road driving, always check the entire
floor assembly, tires, body structure, steering
system, running gear and exhaust system for
signs of damage.fAfter 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.
fIf 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.
Uphill driving
Danger!
Danger of serious personal injury or death
and risk of damage if the vehicle should
overturn.
fDo not turn around when driving uphill.
fIf it is not possible to climb a gradient, the car
must be backed down in reverse gear.
fDo not drive over embankments or slopes at
steep diagonal angles.
fIf the vehicle starts to tilt, immediately steer in
the direction of the tilt (line of slope).
fWhen driving uphill, never let the vehicle roll
backward when in idle or not in gear.
Exclusive use of the footbrake is too risky in such situations.
