fDo not lean over the battery due to danger of chemical burns from leaking acid.
fImproper use of booster battery to start a vehicle may cause an explosion.fKeep sources of ignition away from the battery, e.g. naked flame, burning cigarettes or sparks due to cable contact.fBefore connecting jumper cables, it is essential to thaw out a frozen battery.
Risk of damage due to short circuit.fNever connect jumper cables directly to the battery. Always connect jumper cables to the emergency starting terminals in the luggage compartment.

Supplying external power/ Performing emergency starting with jumper cables
Always observe the sequence below: 1. Remove cover in luggage compartment. To remove the cover:Please see the chapter “TIRE FILLING COMPRESSOR” on page 198.2. Connect the positive lead (red) to the positive terminal A of the discharged battery first, then connect it to the positive terminal of the donor battery.3. Connect the negative lead (black) first to the negative terminal of the donor battery, then to the ground point B. 4. Leave the engine of the donor vehicle running at a higher engine speed.
5. Start the engine. An attempted start using jump leads should not last more than 15 seconds. Then wait for at least one minute.6. With engine running: Disconnect the negative lead from the ground point B first, then from the negative terminal of the donor battery.7. With engine running: Disconnect the positive lead from the positive terminal of the donor battery first, then from the positive terminal A of the discharged battery.
Charging the battery
Automotive batteries lose their efficiency when not in use. The charge available in your battery can be measured with a battery hydrometer. We recommend that the battery voltage be tested by your authorized Porsche dealer who has the appropriate equipment.
If the car is not driven for prolonged periods, the battery must be charged at least every 6 weeks. A discharged battery allows rapid formation of sulfates, leading to premature deterioration of the plates.

1. Switch ignition on. 2. Switch on low beam. 3. Open luggage compartment lid. 4. Remove the relevant toolbox. 5. Open up the cover A for the adjusting screw. 6. Place Allen wrench (5 mm) on adjusting screw. 7. Adjust low beam in the corresponding direction.
Towing
Certain state statutes and local ordinances prohibit towing with a chain, rope or even a tow bar. In addition, damage to your vehicle may result from improper procedures. Consult your authorized Porsche dealer for details.
Flatbed towing is the preferred type of towing to be used on Porsche vehicles.
Information
fAlways observe the laws governing towing and tow-starting.fExercise extreme care when your vehicle is being towed.
No power assistance is available on the towed vehicle when its engine is not running. Greater force is therefore required when braking and steering.fExercise extreme care when your vehicle is being towed.
When the engine is not running, adequate lubrication of the transmission is not guaranteed. Observe the following points to avoid damage to the transmission.
Towing a vehicle on all four wheels
We urge that wherever possible, a car transporter or trailer be used to transport a 911 Turbo vehicle that cannot move under its own power. This is the safest way to transport a down vehicle.
For those instances where a car transporter or trailer is not available, the vehicle may be towed on all four wheels only, provided the following
conditions are strictly met. Failure to meet these conditions will result in serious and expensive damage to the PDK transmission.
If the vehicle's transmission or shifter is already damaged, serious damage will result if the vehicle is not towed with all four wheels off the ground.
Porsche cannot be held responsible for damage incurred in cases where a vehicle has been transported on one or both of its axles.
Towing a vehicle on all four wheels:
fThe vehicle must not be towed if the PDK transmission is in emergency operation mode (“ Transm. failure Park vehicle safely”). The vehicle must be transported with a car transporter or on a trailer.fIf a selector lever emergency release was performed, the vehicle must not be towed. The vehicle must be transported with a car transporter or on a trailer.fMove PDK selector lever to position N. To properly engage selector-lever position N on the display and at the selector lever, the engine must be started once before towing the vehicle. The vehicle can be towed as soon as the selector lever is in position N and selector- lever position N appears on the display.fThe vehicle must always roll on all four wheels when towed.The ignition must be switched on so that the brake lights and turn signal lights operate.fDo not exceed a maximum speed of 30 mph (50 km/h).Maximum towing distance 30 miles (50 km).If towing distances are greater, the vehicle must be transported with a car transporter or on a trailer.

Towing a vehicle on one axle:
Raising an axle, irrespective of whether at the front or rear, is only permissible if the drive shaft (cardan shaft) has been removed beforehand. The ignition must be switched off.fThe vehicle must not be towed if the PDK transmission is in emergency operation mode (yellow or red “ Transm. failure Park vehicle safely ” warning message). The vehicle must be transported with a car transporter or on a trailer.fIf a selector lever emergency release was performed, the vehicle must not be towed. The vehicle must be transported with a car transporter or on a trailer.fMove PDK selector lever to position N. To properly engage selector-lever position N on the display and at the selector lever, the engine must be started once before towing the vehicle. The vehicle can be towed as soon as the selector lever is in position N and selector- lever position N appears on the display.fSwitch ignition off. The ignition key must remain in the ignition lock so that the steering lock does not engage.The control unit must be removed from the ignition lock and the key inserted in vehicles with Porsche Entry & Drive. fPlease see the chapter “EMERGENCY OPERATION – UNLOCKING THE IGNITION KEY/CONTROL UNIT” on page 28.fMake sure that the vehicle is adequately illuminated.
fDo not exceed a maximum speed of 30 mph (50 km/h).Maximum towing distance 30 miles (50 km).If towing distances are greater, the vehicle must be transported with a car transporter or on a trailer.
Pulling out a vehicle stuck in snow, sand, etc.
fAlways pull out the stuck vehicle with the greatest care.fDo not pull out the vehicle abruptly or at an angle. fIf possible, pull the vehicle out backwards in its own tracks.
PDK selector lever emergency release
In the event of an electronics failure, emergency release of the selector lever must be performed in order to move the selector-lever to the N position.
Releasing selector lever
1. Take the plastic wedge from the toolbox. 2. Carefully lever out the rear part of the selector lever gate A on both sides (arrows) using the plastic wedge.3. Carefully lever out the front part of the switch panel B on both sides (arrow) using the plastic wedge.4. Remove the switch module B and place aside. The cable C of the switch panel must not be under tension.

Filling Capacities
Only use fluids and fuels approved by Porsche. Your Porsche dealer will be pleased to advise you.
Engine oil change quantity with oil filter approx. 1.98 US gallons (7.5 liters)
Fuel tankapprox. 18.0 US gallons (68 liters), including approx. 3.17 US gallons (12 liters) reserve
