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 wi th 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.
f To 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.
f Never carry additional fuel in portable contai-ners in your vehicle.
Ground Clearance
Caution!
Risk of damage. The vehicle may touch the
ground as a result of reduced ground clear-
ance.
f Drive carefully and slowly on steep slopes
(e. g. parking lots, curbs, uneven roads, lifting
platforms etc.).
fAvoid steep ramps.
Porsche Ceramic Composite Brake
(PCCB)f Please see the chapter “BRAKES” on
Page 172.
The high-performance brake system is designed
for optimal braking effect at all speeds and
temperatures.
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
increases considerably when the vehicle is driven
on race tracks or through an aggressive driving
style.
f Please 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 we aring-in occurs mainly in
the first 2,000 miles (3,000 km).Therefore:f Preferably take longer trips.
f Avoid frequent cold starts with short-distance
driving whenever possible.
f Avoid full throttle starts and abrupt stops.
f Do not exceed maximum engine speed of
4,200 rpm (revolutions per minute).
f Do not run a cold engine at high rpm either in
Neutral or in gear.
f Do not let the engine labor, especially when
driving uphill. Shift to the next lower gear in
time (use the most favorable rpm range).
f Never lug the engine in high gear at low
speeds. This rule applies at all times, not just
during the break-in period. f
Do 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 or
other controls during the br eak-in period which will
gradually disappear.
Break in brake pads and brake discsNew brake pads and discs ha ve 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.
f Break 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 peri od oil and fuel consump-
tion may be higher than normal.
f Please see the chapter “ENGINE DATA” on
Page 324.
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.
f Make a habit of checking engine oil with every
refueling, add if necessary.

Driving and Driving Safety
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
applications.
Warning!
Risk of an accident, resulting in serious
personal injury or death.
Driving through water may reduce the
traction. Moisture on brakes from road
water, car wash, or a coating of road salt or
grit may affect braking efficiency.
f Cautiously 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.
f Have the brake system inspected at the
intervals recommended in your Maintenance
Booklet.
Brake system warning light
You can check the functionality of the brake
system warning light by switching the ignition to
the “On” position (position 1) and verifying that the
warning light illuminates.
A warning message will be displayed on the multi-
function display of the instrument panel if the
brake pads are worn, excessively.
f Do not continue to operate the vehicle.
Have your authorized Porsche dealer inspect
or replace the brake pads.
For information on warning messages on the
multi-function display:
f Please see the chapter “OVERVIEW OF
WARNING MESSAGES” on page 152.
Brake pads and brake discsWear on the brake pads and brake discs depends
to a great extent on the driving style and the
conditions 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
temperatures.
Certain speeds, braking forces and ambient
conditions (e.g. temperature and humidity) can
therefore cause the brakes to “squeal”.
New brake pads or linings
New brake pads 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 applies whenever the brake pads
and/or brake discs are replaced.
Brake wear warning message

Driving and Driving Safety
175
Warning!
f Do 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.
f Vehicles with defective brakes must not
be towed and must be transported on a flat
bed.
For information on towing and tow-starting:
f Please see the chapter “TOWING” on
page 316.
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.
f For this reason, keep further back from the
vehicle in front and “dry” the brakes by
applying them at interval s. Make sure that the
traffic behind you is not affected. After a long drive over salted or gritted roads,
a coating may form on the brake discs and pads
that significantly reduces
friction and therefore
also braking effect.
f Even though the brake discs consist of alloyed
grey cast iron, they will unavoidably start to
corrode if your vehicle 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 vehicle
(not on vehicles with Porsche Ceramic
Composite Brake).
If braking comfort is no ticeably impaired, we
recommend that you have the brake system
checked by an authorized Porsche dealer. f
To relieve the brake system on downhill
stretches, change down to a lower gear in
good time (engine braking).
If engine braking is insufficient on steep
stretches, operate the footbrake at intervals.
Avoid continuous braking as it overheats the
brakes and reduces the braking effect.
For information on brake fluid and checking the
brake fluid level:
f Please see the chapter “BRAKE FLUID” on
page 258.

Driving and Driving Safety
– Brake system prefilling:
The brake system is prepared for possible
subsequent 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 (Hydraulic Brake Assist): In the event of an emergency braking operation
where the pedal force is insufficient, a brake
booster provides the braking pressure
necessary for maximum deceleration at all
4wheels.
Combined operation of PSM and PTM
In order to ensure optimum stabilisation of the
vehicle, torque distribution between the front and
rear wheels is adapted and the rear differential
lock is controlled on vehicles with PDCC.
In the event of a PTM fault, PSM cannot be
switched off.
If PSM is switched off, it is switched on again
automatically. Automatic brake differential (ABD)
The ABD system controls the front and rear axles
separately. If one wheel of an axle starts to spin,
it is braked so that the other wheel on the same
axle can be driven.
ABD recognizes different driving states, and it
features control strategies adapted to these
states. In situations in which little propulsive power
is required, such as when the vehicle moves off on
a level gravel surface, traction control already
becomes active at low engine speeds. If a large
amount of propulsive power is required, e.g. when
driving off on an uph
ill slope or for rapid
acceleration, the ABD system is adapted
accordingly.
Anti-slip control (ASR)
The anti-slip control system prevents the wheels
from spinning by adjusting the engine power,
thereby ensuring good lane-holding ability and
stable handling.
Engine drag torque control (MSR)
In conditions of excessive slip, the engine
drag torque control system prevents all driven
wheels from locking up when the vehicle is
overrunning. This is also the case for downshifts
on a slippery road.
Switching off PSMf Press button for at least 1 second.
PSM is switched off after a short delay.
The indicator light on the button and the
PSM OFF warning light on the instrument
panel light up.
The warning “PSM off” appears on the
multi-function display in the instrument panel.
