Risk of damage to the fabric, metal or paint from battery acid or electrolyte.fDo not allow battery acid to come in contact with fabric or painted surfaces.fSpilled electrolyte must be rinsed off at once with a solution of baking soda and water to neutralize the acid.
Charge state
A well-charged battery prevents starting problems and has a longer service life.
In order to avoid unintentional battery discharge:
fSwitch off unnecessary electrical loads in city traffic, on short trips or in a line of traffic.fAlways remove the ignition key when leaving the vehicle orswitch off the ignition on vehicles with Porsche Entry & Drive.fAvoid using the Porsche Communication Management system and the audio system when the engine is not running.fPlease see the chapter “CHARGING THE BATTERY” on page 274.
Information
In the cold season in particular or if the vehicle is used primarily for short distances, it may be necessary to recharge the battery from time to time.
Battery care
fEnsure that battery is securely mounted.fKeep battery surface clean and dry.fKeep terminals and connections clean. Corrosion can be prevented by coating the terminals and connections with petroleum jelly or silicone spray.fEnsure that terminal clamps and the vent hose are firmly secured.
Winter driving
The ability of the battery to deliver and store power decreases at low outside temperatures. Moreover, the battery is more heavily loaded in the winter months, e.g. by the heated rear window, the more frequent use of additional lights, the blower and the windshield wipers, etc.fHave the battery checked before the start of winter.
Information
Keep the battery fully charged to prevent it from freezing.
A discharged battery can already freeze at –5 ºC, but a fully charged one only freezes at –40 ºC. fIf the battery is frozen, thaw it out before connecting jump leads.
Laying up the vehicle
If the vehicle is left for long periods in the garage or workshop, the doors and lids should be closed.fRemove the ignition key or disconnect the battery if necessary.
Information
fWhen the battery is disconnected, the alarm system ceases to function.
If the vehicle was locked before the battery was disconnected, the alarm will be triggered when the battery is reconnected.To deactivate the alarm system: fLock the vehicle and unlock it again.
Alarm system, central locking
fThe status of the central locking and alarm system does not change when you disconnect the battery.
Information
Even if you put your vehicle out of operation, the battery still discharges.fThe battery must be charged, i.e. connected to a charger, approximately every 6 weeks in order to preserve battery function.fStore a battery that has been removed in a dark, cool place that is not exposed to frost.
Replacing the battery
The battery is subject to normal wear: its service life depends heavily on the care you give it, climatic conditions and the conditions of use (distances, loads).
It is not possible to use the details on the battery case to determine a comparable battery that meets all the specific requirements of Porsche.fHave the battery removed and installed only by your authorized Porsche dealer.fOnly use an original Porsche battery, with the correct part number, as a replacement. Only this battery meets the specific requirements of the vehicle.

Minor Repairs 273
fAfter you install a new battery, it must be initialized in the control unit.Please contact your authorized Porsche dealer.fPlease observe the disposal instructions for batteries.
Putting vehicle into operation
After the battery is connected or after a fully discharged battery is charged, the PSM warning light lights up on the instrument panel and a message appears on the multi-function display in the instrument panel to indicate a fault.
This fault can be corrected with a few simple steps: 1. Start the engine. To do this, turn the ignition key or the control unit (on vehicles with Porsche Entry & Drive) to ignition lock position 2 twice. 2. With the vehicle stationary, perform a few steering movements to the left and right and then drive a short distance in a straight line until the PSM warning light goes out and the message is erased from the multi-function display in the instrument panel.3. If the warnings do not disappear, then: Drive carefully to the nearest authorized Porsche dealer.Have the fault corrected.4. After the warnings go out: Stop the vehicle in a suitable place.5. Store the end position for the power windows.
For information on storing the end positions for the power windows: fPlease see the chapter “STORING END POSITION OF THE WINDOWS AFTER CONNECTING THE VEHICLE BATTERY” on page 63.6. Teach tires on vehicles with Tire Pressure Monitoring.
For information on teaching the Tire Pressure Monitoring System (TPMS): fPlease see the chapter “TIRE PRESSURE MENU (TIRE PRESSURE MONITORING SYSTEM, TPMS)” on page 105.7. Store end position on vehicles with a sunroof.
For information on storing the end position for the sunroof: fPlease see the chapter “STORING END POSITION OF THE SUNROOF” on page 66.fPlease see the chapter “STORING END POSITION OF THE ROLL-UP SUNBLIND” on page 67.
External Power Supply, Emergency
starting with jumper cables
If the battery is flat, the battery of another vehicle can be used for starting or as an external power supply with the help of jump leads.
Both batteries must be 12 V batteries. The capacity (Ah) of the donor battery must not be substantially less than that of the flat battery.
The flat battery must be connected correctly to the vehicle’s electrical system.
A short circuit may be caused if unsuitable jumper cables are used or if jumper cable starting is not performed properly. Such short circuits can cause a fire.fUse only standard jumper cables with sufficient cross section and completely insulated alligator clips. Follow the instructions provided by the jumper cable manufacturer.fRoute the jumper cables so that they cannot be caught by moving parts in the engine compartment.The jumper cables must be long enough so that neither vehicles nor cables touch another.fThe vehicles must not touch, otherwise current might flow as soon as the positive terminals are connected.fEnsure that tools or conductive jewelry (rings, chains, watch straps) do not come into contact with the positive jumper cable, the positive battery post or live parts of the vehicle.fImproper hook-up of jumper cables can ruin the alternator.

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.

286 Tire Pressure and Technical Data
Wheels, Tires
fApproval of tire and wheel sizes is granted based on extensive testing. By fitting tires that have been approved by Porsche, you can be sure that you have the best possible tires for your Porsche.The load capacity coefficient (e.g. “91”) and maximum speed code letter (e.g. “Y”) for permitted top speed are minimum requirements. When fitting new tires or changing tires: Please see the chapter “TIRES AND WHEELS” on page 244.fSnow chain clearance can only be guaranteed with the tires marked 1). Snow chains can only be fitted on the rear wheels. Observe state or province-specific laws regarding maximum speeds with fitted snow chains.
