Driving and Driving Safety

ABS Brake System
(Anti-Lock Brake System)
Warning!
In spite of the advantages of ABS, it is still the
driver’s responsibility to adapt his driving style and
maneuvers in line with road and weather
conditions, as well as the traffic situation.
The increased safety that is provided should not
induce you to take greater risks with your safety.
The limits set by the physic s of driving cannot be
overcome, even with ABS.
Risk of accidents due to inappropriate speed
cannot be reduced by ABS.
ABS ensures
– Full steering control
The vehicle remains steerable
– Good driving stability
No skidding due to locked wheels
– Optimum braking distance
Shorter stopping distance in most cases
– Prevention of wheel locking
No flat spots on the tires Function
The decisive advantage of ABS lies in the driving
stability and maneuverability of the vehicle in
hazardous situations.
ABS prevents locking of
the wheels during full
braking, on almost all road surfaces, until just
before the vehicle stops.
ABS begins to control the braking process as
soon as a wheel shows a tendency to lock.
This controlled braking process is comparable
with extremely rapid cadence braking.
The pulsating brake pedal and a “juddering noise”
warn the driver to adapt his driving speed to the
road conditions.
f If full braking is necessary, press the brake
pedal fully during the whole braking operation,
even though the pedal is pulsating. Do not
reduce brake pressure. If the ABS warning light lig
hts up on the instrument
panel while the engine is running, the ABS has
switched off because of a fault.
The warning message “ABS failure” appears on
the multi-function display in the instrument panel.
For information on warning messages on the
multi-function display:
f Please see the chapter “OVERVIEW OF
WARNING MESSAGES” on page 152.
In this case, the brake system will operate without
lock prevention, as on vehicles without ABS.
f Adapt your driving style to the changed
braking behavior.
The ABS must be checked by your authorized
Porsche dealer in order to prevent the
occurrence of further faults with unpredictable
consequences.
Please contact a qualified specialist workshop.
We recommend that you have an authorized
Porsche dealer to do this work as they have
trained workshop personnel and the necessary
parts and tools.
The ABS control unit is adjusted for the approved
tire dimensions.
The use of tires with no n-approved dimensions can
lead to different wheel speeds, causing ABS to
switch off. Warning light USA

Stowing Loads
Danger!
Danger of injury. An unsecured or incorrectly
positioned load can slip out of place or
endanger the vehicle occupants during
braking, direction changes or in accidents.
Never transport objects that are not secured.
f Always transport loads in the luggage
compartment, never in the passenger
compartment (e.g. on or in front of the seats).
f Support the load against the seat backrests
wherever possible. Always lock the backrests
into place.
f Only transport heavy objects with the rear seat
backrests upright and engaged.
f Place the load behind unoccupied seats
whenever possible.
f Stow heavy objects as far forward as possible
on the floor, with lightweight objects behind
them.
f Never load the vehicle higher than the top
edge of the seat backrest.
f Always protect the passenger compartment
with a luggage compartment cover. Do not
drive with objects on top of the luggage
compartment cover. f
If the rear seats are not occupied, the
backrests can be addition ally secured with the
seat belts. Simply cro ss the outer seat belts
and insert each into the opposite buckle.
f Make sure that the load cannot damage the
heating filaments and the TV antenna in the
rear window.
Tie-down belts
f Do not use elastic belt s or straps to tie
down a load.
f Do not route belts and straps over
sharp edges.
f Observe the directions for use and information
for the tie-down equipment.
f Use only belts with a tear strength of at least
1543 lbs (700 kg) and a maximum width of
1 in. (25 mm).
f Cross the belts over the load. Driving
f
Vehicle handling changes depending on the
vehicle load. Adapt your driving style to the
changed driving behavior.
f Do not exceed the maximum gross weight
and axle load.
This information can be found under “Technical
data” in this Owner’s Manual:
f Please see the chapter “WEIGHTS” on
page 328.
f Never drive with the tailgate open. Exhaust
gases can enter the passenger compartment.
f Adapt the tire pressure to the load.
After you change the tire pressure, you must
also update the setting for Tire Pressure
Monitoring.
For information on setting Tire Pressure
Monitoring on the multi-function display:
f Please see the chapter “OVERVIEW OF
WARNING MESSAGES” on page 152.
Information on tire pressures for partially and fully
loaded vehicles can be found under “Technical
data” in this Owner’s Manual:
f Please see the chapter “TIRE PRESSURE FOR
COLD TIRES (68 °F/20 °C)” on page 326.

Loading InformationDefinitionsThe rear-axle load is the vehicle weight on the
rear axle plus the weight of the transported load.
The Curb weight - actual weight of your vehicle -
vehicle weight including standard and optional
equipment, fluids, and emergency tools. This
weight does not include passengers and cargo.
The Gross Vehicle Weight is the sum of the curb
weight and the weight of passengers and cargo
combined.
The Gross Vehicle Weight Rating is the
maximum total weight of vehicle, passengers,
luggage, hitch, trailer tongue load and optional
equipment.
The Gross Axle Weight Rating is the maximum
load limit for the front or the rear axle. This
information is located on the safety comliance
sticker located in the dr iver’s side door jamb.
For determining the compat ibility of the tire and
vehicle load capabilities:
f Please see the chapter “TIRES AND WHEELS”
on page 280. The load capacity coefficient (e.g. “106”) is a
minimum requirement. For more information:
f
Please see the chapter “INSCRIPTION ON
RADIAL TIRE” on page 288.
The Gross Combined Weight Rating is the
maximum total weight rating of vehicle,
passengers and cargo.
The Vehicle Capacity Weight - Load Limit - is
the maximum total weight limit specified of the
load (passengers and cargo) for the vehicle. This
is the maximum weight of passengers and cargo
that can be loaded into the vehicle. This infor-
mation can be found on the tire pressure plate.
The maximum loaded vehicle weight is the
sum of curb weight, acce ssory weight, vehicle
capacity weight and production options weight.
The load rating is the maximum load that a tire
is rated to carry for a given inflation pressure.
The maximum load rating is the load rating for
a tire at the maximum permissible inflation
pressure.
The cargo capacity is the permissible weight of
cargo, the subtracted weight of passengers from
the load limit.
f Never exceed the permissible limits.
Danger!
Risk of personal injury or death.
Injuries are much more likely in an accident
if persons ride in the cargo area.
f Persons must ride only on the seats provided
for this purpose.
f Make sure that everybody fastens their safety
belts.
Risk of loss of control, damage to the vehicle
and serious personal injury or death.
f Never exceed the specified axle loads.
Overloading can shorten the service life of the
tires and car, as well as lead to dangerous
vehicle reactions and long braking distances.
Damage due to overloading is not covered by the vehicle warranty.

Example for determining the combined weight of
occupants and cargoVehicle Load CapacityfThe combined weight of occupants and cargo
should never exceed the weight shown on the
tire plate in the vehicle.
Please see the chapter “TIRE PRESSURE
PLATE” on page 323.
f Never exceed the number of passengers
shown on the tire pressure plate in the vehicle. Determining the combined weight of
occupants and cargo:
f
Add the weight of all occupants and then add
the total luggage weight ( figure).
Steps for determining correct load limit
1. Locate the statement “The combined weight of occupants and cargo should never exceed XXX
pounds” on your vehicle’s placard (depending
on the date of manufacture).
2. Determine the combined weight of the driver and passengers that will be riding in your
vehicle.
3. Subtract the combined weight of the driver and passengers from XXX kilograms or XXX
pounds.
4. The resulting figure equals the available amount of cargo and luggage load capacity.
For example, if the “XXX” amount equals 1400
lbs. and there will be five - 150 lb passengers
in your vehicle, the am ount of available cargo
and luggage load capacity is 650 lbs. [1400 -
750 (5 x 150) = 650 lbs.].
5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load ca pacity calculated in
Step 4.

Maintenance and Car Care
Fuel EconomyFuel economy will vary depending on where,
when and how you drive, optional equipment
installed, and the general condition of your
car.
A car tuned to specifications and correctly
maintained, will help you to achieve optimal
fuel economy.
fHave your vehicle tuned to specifications. Air
cleaner should be dirt free to allow proper
engine “breathing”.
Battery should be fully charged.
Wheels should be properly aligned.
Tires should be inflated to the correct
pressure.
f Always monitor your fuel consumption.
f Drive smoothly, avoid abrupt changes in speed
as much as possible.
f Avoid jack rabbit starts and sudden stops.
f Do not drive longer than necessary in the lower
gears. Shifting into a higher gear early without
lugging the engine will help save fuel.
f Prolonged “warm up” idling wastes gas. Start
the vehicle just before you are ready to drive.
Accelerate slowly and smoothly.
f Switch off the engine if stationary for longer
periods.
f Any additional weight carried in the vehicle
reduces fuel economy. Always keep cargo to
a minimum and remove all unnecessary items. f
Organize your trips to take in several errands
in one trip.
f All electrical accessories contribute to
increased fuel consumption.
f Only switch on the air conditioning when
necessary.
f Do not drive with the Ro of Transport System
mounted unless you need it.
The EPA estimated miles per gallon (mpg) is
to be used for comparison purposes, actual
mileage may be different from the estimated
mpg, depending on your driving speed,
weather conditions and trip length. Your
actual highway mileage may be less than the
estimated mpg.
f Please observe all local and national speed
limits.
Operating Your Porsche in other
CountriesGovernment regulations in the United States and
Canada require that automobiles meet specific
emission regulations and safety standards.
Therefore, cars built for the U.S. and Canada differ
from vehicles sold in other countries.
If you plan to take your Porsche outside the
continental limits of the United States or Canada,
there is the possibility that
– unleaded fuel may not be available;
– unleaded fuel may have a considerably lower
octane rating. Excessi ve engine knock and
serious damage to both engine and catalytic
converters could result;
– service may be inadequate due to lack of proper service facilities, tools or diagnostic
equipment;
– replacement parts may not be available or very difficult to get.
Porsche cannot be responsible for the
mechanical damage that could result
because of inadequate fuel, service or parts
availability.
If you purchased your Porsche abroad and want to
bring it back home, be sure to find out about
shipping and forwarding requirements, as well as
current import and customs regulations.
