170 Driving and Driving Safety
If aftermarket systems are installed by non- dealership technicians or outside the selling dealer, problems may result. Installation of aftermarket equipment is not covered under the New Car Warranty. fConsult your authorized Porsche dealer about the installation of non-Porsche approved equipment.
Reception quality
The reception quality of your car telephone will change constantly when you are driving. Interference caused by buildings, landscape and weather is unavoidable. It may become particu-larly difficult to hear when using the hands-free function due to external noise such as engine and wind noise.
Automatic car-wash
fUnscrew external antennas before using an automatic car-wash.
Porsche Communication
Management (PCM)
Setting or operating the multi-function display, radio, navigation system, telephone or other equipment when driving could distract you from the traffic. You could lose control of the vehicle.fOperate the components while driving only if the traffic situation allows you to do so safely.fCarry out any complicated operating or setting procedures only with the vehicle stationary.fIf it is necessary to operate these components while the vehicle is in motion, use the function keys on the multi-functional steering wheel.
fRefer to the separate operating instructions before putting the PCM into operation.
When put into operation for the first time, a distance of approx. 3 miles (5 km) must be driven in order for the navigation system to complete the process of fine calibration. The same applies when the tires are changed (e.g. summer/snow tires) or new tires fitted. Full location accuracy is not yet achieved during the fine-calibration process.
If the vehicle has been transported (e.g. ferry, car train), the system may take a few minutes after being switched on before it determines the current location.
Serious tire slip (e.g. spinning wheels on snow) may result in temporarily inaccurate navigation.
When the battery has been disconnected, it may take up to 15 minutes before the navigation system is operational once more.
Satellite radio
You must have the satellite radio activated before you can put it into operation. You will need a contract with a provider in order to use this radio.fRefer to the separate radio operating instructions before putting into operation.

184 Driving and Driving Safety
HOLD function: Drive-Off
Assistant, Standstill Management
The HOLD function, as an assistance function, assists the driver when stopping and driving off on upward slopes.The vehicle is automatically prevented from rolling back away from the desired direction of travel.When the HOLD function is active, the indicator light on the instrument panel comes on.
The vehicle is stopped and prevented from rolling back away from the desired direction of travel even without pressing the brake.
Information
The HOLD function is not available if the PDK selector lever is in position P and N.
If the PDK selector lever is moved while the HOLD function is active, the HOLD function is deactivated.
If the driver’s safety belt is unfastened and the driver’s door is opened while the HOLD function is active, the electric parking brake is activated automatically.
For information on the electric parking brake:fPlease see the chapter “ELECTRIC PARKING BRAKE” on page 151.
The limits set by the physics of driving cannot be overcome, even with the HOLD function. Responsibility for driving off on upward slopes is still the driver’s, despite the HOLD function.Assistance by the HOLD function is not always guaranteed when stopping and driving off on a slippery surface (e.g. on icy or loose surfaces). In this case, the vehicle can slip.fAlways adjust your driving style to the driving conditions and vehicle load. Use the footbrake if necessary.
If the Drive-Off Assistant is not functioning, the driver cannot be assisted when driving off on hills.fHold the vehicle with the footbrake.
If the vehicle comes to a standstill on a steep uphill gradient without operation of the footbrake by the driver, this may result in a certain roll-back before the vehicle is held by the HOLD function. In this situation, the roll-back can be reduced by pressing the footbrake.fAssist holding of the vehicle by increasing the braking force with the footbrake.
Information
When the HOLD function is active, the brake pedal may feel different and you may hear hydraulic noises.
This behavior is normal for the system. It is not a fault.
ABS Brake System
(Anti-lock Brake System)
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 physics of driving cannot be overcome, even with ABS.Risk of accidents due to inappropriate speed cannot be reduced by ABS.
ABS helps provide:
– 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

Driving and Driving Safety 185
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.fIf 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.
Warning light USA
Warning light Canada
If the ABS warning light lights up on the instrument panel while the engine is running, the ABS has switched off because of a fault.The warning message “ ABS/PSM failure Adapted driving permitted ” appears on the multi-function display in the instrument panel.
For information on warning messages on the multi- function display: fPlease see the chapter “OVERVIEW OF WARNING AND INFORMATION MESSAGES” on page 129.
In this case, the braking system will operate without lock prevention , as in vehicles without ABS.fAdapt 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 an authorized Porsche dealer.
The ABS control unit is adjusted for the approved tire dimensions.The use of tires with non-approved dimensions can lead to different wheel speeds, causing ABS to switch off.
Porsche Active Suspension
Management (PASM)
The PASM system actively adjusts the shock absorbers. The adjustable damper system selects the appropriate damping level for each wheel according to the driving situation and driving conditions. Driving safety, agility and comfort are optimized.
Two different chassis setups can be selected at the push of a button:–“ Chassis Normal” –“ Chassis Sport”
In Normal mode the vehicle is in a sporty and comfortable setup.Sport mode offers very sporty shock absorber tuning (e.g. for driving on the race circuit).
In addition to manual mode selection, PASM also adjusts shock absorber tuning for either sporty or comfort driving, depending on the driving situation.

Loading Information
Definitions
The 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 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 compliance sticker located in the driver’s side door aperture area.
For determining the compatibility of the tire and vehicle load capabilities:fPlease see the chapter “TIRES AND WHEELS” on page 244.
The load capacity coefficient (e.g. “106”) is a minimum requirement. For more information:fPlease see the chapter “INSCRIPTION ON RADIAL TIRE” on page 252.
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, accessory 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.fNever exceed the permissible limits.
Injuries are much more likely in an accident if persons ride in the cargo area.fPersons must ride only on the seats provided for this purpose. fMake sure that everybody fastens their safety belts.
Overloading will lead to dangerous vehicle reactions and long braking distances.fNever exceed the specified axle loads.
Risk of damage to the vehicle if the vehicle is overloaded.

226 Maintenance and Car Care
Undercoating
Additional undercoating or rust protection agents on or near the exhaust system can become too hot when driving and ignite, causing a fire.fDo not apply additional undercoating or rust protection agent on or near the exhaust manifolds, exhaust pipes, catalytic converters or heat shields. During driving the substance used for undercoating could overheat and ignite.
How Emission Control Works
When an automobile engine is running, it uses energy generated through the combustion of a mixture of air and fuel. Depending on whether a car is driven fast or slowly or whether the engine is cold or hot, some of the fuel (hydrocarbons) may not be burned completely, but may be discharged into the engine crankcase or exhaust system. Additional hydrocarbons may enter the atmosphere through evaporation of fuel from the fuel tank. These hydrocarbons (HC), when released into the air, contribute to undesirable pollution.
In addition, carbon monoxide (CO) and oxides of nitrogen (NOx) contribute to engine emissions. They, too, are formed during the combustion process and discharged into the exhaust system.
To reduce these pollutants, your Porsche is equipped with a precisely calibrated fuel injection system to assure a finely balanced air/fuel mixture under all operating conditions.
Oxygen sensor
The oxygen sensor, installed in the exhaust pipe continuously senses the oxygen content of the exhaust and signals the information to an electronic control unit. The control unit corrects the air/fuel ratio, so the engine always receives an accurately metered air/fuel mixture.
Crankcase ventilation
Through crankcase ventilation, undesirable emissions from the engine crankcase are not permitted to reach the outside atmosphere. These emissions are recirculated from the crankcase to the air intake system. From here the emissions mix with the intake air and are later burned in the engine.
Catalytic converters
The catalytic converters are efficient “clean-up” devices built into the exhaust system of the vehicle. The catalytic converters burn the undesirable pollutants in the exhaust gas before it is released into the atmosphere.
The exclusive use of unleaded fuel is critically important for the life of the catalytic converters. Therefore, only unleaded fuel must be used.
The catalytic converters will be damaged by:
– Push or tow starting the vehicle, – Misfiring of the engine,– Turning off the ignition while the vehicle is moving,– Driving until the fuel tank is completely empty,– By other unusual operating conditions.fDo not continue to operate your vehicle under these conditions, since raw fuel might reach the catalytic converters. This could result in overheating of the converters. Federal law prohibits use of leaded fuel in this car.
Fuel Economy
Fuel 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.

232 Maintenance and Car Care
High-pressure cleaning equipment, steam cleaners
Risk of damage as a result of using high-pressure cleaning equipment, steam cleaners or similar.
High-pressure cleaning equipment, steam cleaners or similar can damage the following components:– Convertible top– Tires– Logos, emblems– Painted surfaces– Alternator– Electrical components and plug connections in the engine compartment– ParkAssist sensors– Radar sensor for adaptive cruise control– Reversing camerafAlways read the operating instructions provided by the equipment manufacturer.fAlways cover the lid of the brake fluid reservoir prior to cleaning. Never point the cleaning jet directly at the lid.fWhen cleaning with a flat-jet nozzle or a so-called “dirt blaster”, maintain a minimum distance of 20 in. (50 cm).fNever use high-pressure cleaning equipment or steam cleaners with a round-jet nozzle.A high-pressure cleaning device or steam cleaner fitted with a round nozzle will damage your vehicle. The tires are particularly susceptible to damage.fDo not point the cleaning jet directly at any of the aforementioned components.
Decorative film
Risk of damage due to separation of the decorative film when using high-pressure cleaning equipment, steam cleaners or similar cleaning equipment.fDo not use high-pressure cleaning equipment, steam cleaners, etc. to clean decorative films.
Care of door lock
fTo prevent the door lock from freezing during the cold season, cover the lock barrel with suitable adhesive tape while washing the vehicle.
If the lock still freezes, use an ordinary de-icer. In many cases, a well warmed key can help.fNever use excessive force.
Car washing
The best protection for the vehicle from the damaging effects of the environment is frequent washing and preservation.
The longer road salt, road dust, industrial dust, insect remains, bird excrement, and tree exudations (e.g. resin, pollen), etc. are allowed to remain on the bodywork, the more harmful their effect.
Observe the following points in order to ensure that the vehicle is washed thoroughly without damaging the paintwork: fThe underside of the vehicle should also be thoroughly washed at the end of the gritting season at the latest.fWash your vehicle only at sites provided for this purpose to prevent soot, grease, oil and heavy metals from entering the environment.
fNew cars should be washed carefully with plenty of clear water to protect the new paint work. Dark paint finishes show up the smallest of surface damage (e.g., scratches) more readily than lighter colors. Dark colors are slightly more susceptible to scratching and require particularly careful paint care.Dark paints make even the smallest surface blemishes (scratches) more conspicuous than lighter colors.fDo not wash your Porsche in direct sunlight or when its body is hot.fWhen washing by hand, use a car shampoo, plenty of water, and a soft sponge or washing brush.We recommend Porsche car shampoo.fStart washing the vehicle by thoroughly wetting the paintwork and rinsing the heavy dirt off.fAfter washing the vehicle, rinse it thoroughly with water and rub it dry with chamois-leather.Do not use the same chamois for rubbing dry as you use for cleaning the windshield and windows.
Reduced or uneven braking action may be caused by wet brakes.fAfter washing the vehicle, test the brakes and steering and briefly brake the disks dry.When doing so, make sure that vehicles traveling behind you are not affected.
