150 Driving and Driving Safety
Information
The engine will start automatically in certain situations, e.g. if the vehicle starts rolling, if air conditioning causes reduced comfort, or if the brake vacuum is reduced.The engine is stopped again automatically if the preconditions for stopping the engine automatically are then met again.
Exceptions for the Auto Start Stop function
The Auto Start Stop function is deactivated e.g.: – When Sport mode is activated.– When PSM is off.– In maneuvering mode.– When A/C MAX mode is activated.– When the “Windshield defrost” function is active. – At altitudes above approx. 9,843 ft. (3,000 meters)
For information on switching on and off the Auto Start Stop function:fPlease see the chapter “SWITCHING AUTO START STOP FUNCTION AND COASTING MODE ON AND OFF” on page 150.
The Auto Start Stop function is available with limited functionality in the following situations, e.g.:– If the air conditioning or passenger compartment heating is operated at a high setting or if the defrost function is run for long time periods.– If the battery charging condition is low.– On upward or downward slopes.– During internal vehicle test procedures, e.g. automatic engine checks.
Information
If one of these situations arises after the engine has stopped automatically, the engine can be restarted automatically.
Reaction after leaving the vehicle (selector-lever position D or N selected)
If the vehicle is left after an automatic stop when PDK selector-lever position D or N is engaged, an automatic engine start is executed to remind the driver that the Auto Start Stop function is still active.
In selector-lever position D, the electric parking brake is additionally engaged.
The brake warning light on the instrument panel and the indicator light on the switch light up.fPlease see the chapter “OVERVIEW OF WARNING AND INFORMATION MESSAGES” on page 129.
Reaction after leaving the vehicle (selector-lever position P selected)
If the vehicle is left after an automatic stop when PDK selector-lever position P is engaged, in order to open the garage door, for example, no automatic engine start is executed. Auto Start Stop mode is resumed if the driver closes the driver’s door and presses the brake within 30 seconds of leaving the vehicle.
If one of these requirements is not met, the engine has to be started manually. The
message “ Please start engine manually” will appear on the multi-function display in the instrument panel.fPlease see the chapter “OVERVIEW OF WARNING AND INFORMATION MESSAGES” on page 129.

Maintenance and Car Care 227
fAlways monitor your fuel consumption.fDrive smoothly, avoid abrupt changes in speed as much as possible.fAvoid jack rabbit starts and sudden stops.fDo not drive longer than necessary in the lower gears. Shifting into a higher gear early without lugging the engine will help save fuel.fProlonged “warm up” idling wastes gas. Start the vehicle just before you are ready to drive. Accelerate slowly and smoothly.fSwitch off the engine if stationary for longer periods.fAny additional weight carried in the vehicle reduces fuel economy. Always keep cargo to a minimum and remove all unnecessary items.fOrganize your trips to take in several errands in one trip.fAll electrical accessories contribute to increased fuel consumption.fOnly switch on the air conditioning when necessary.fDo not drive with the Roof 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.fPlease observe all local and national speed limits.
Operating Your Porsche in other
Countries
Government 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. Excessive 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.
Fuel
When the ignition is on, the fuel level is displayed on the instrument panel.fPlease see the chapter “FUEL GAUGE” on page 90.
fFire, open flame and smoking are prohibited when handling fuel.
Fuel and fuel vapors are hazardous to health.fAvoid contact with skin or clothing, since injury to your skin may occur.fDo not inhale fuel vapors, since they may make you ill and possibly cause death if inhalation is prolonged and occurs in a closed space.
To prevent damage to the emission control system and engine:fNever drive the tank dry.fAvoid high cornering speeds after the warning lights have come on.
fPlease see the chapter “FUEL ECONOMY” on page 226.
Check engine warning light
If the warning lights in the instrument panel come on and remain on while driving, it suggests: – a potential engine control problem and the need for system service or – an improperly fastened tank cap or
refueling with engine running.

Electrical System
In order to avoid damage and faults in electrical or electronic systems, electrical accessories should be installed at an authorized Porsche dealerfUse only accessories approved by Porsche.
Replacing fuses or relays with the engine running or the ignition on could cause electrical shock.fDisconnect the negative terminal on the battery during all work on the electrical system.fPlease see the chapter “BATTERY (12 VOLT)” on page 271.
Relays
Relays should be checked or changed only at an authorized workshop.
Changing fuses
In order to prevent damage to the electrical system due to short circuits and overloads, the individual circuits are protected by fuses.
The fuse boxes are located in the side walls of the driver’s and passenger’s footwell respectively. 1. Switch off the load with the defective fuse. 2. Detach the appropriate plastic cover at the finger hole.3. Remove the relevant fuse (see fuse assignment) from its slot using the yellow plastic gripper A (left fuse box) in order to check it.A blown fuse can be identified by the melted metal strip.4. Replace only with fuses of the same rating. Spare fuses can be found in the left-hand fuse box, next to the yellow plastic gripper.We recommend that you use genuine Porsche fuses for replacement.
Information
If a fuse blows repeatedly, the cause of the fault must be corrected immediately.fPlease contact an authorized Porsche dealer.
