Dear Porsche Owner
A lot has gone into the manufacture of your Porsche, including advanced engineering techniques, rigid quality control and demanding inspections. These engineering and safety features will be enhanced by you the safe driver who knows his car and all controls who maintains his vehicle properly who uses his driving skills wisely, and who always drives within his own capabilities and his level of familiarity with his vehicle. You will find helpful hints in this manual on how to perform most of the checks listed on these pages. If in doubt, have these checks performed by your Porsche dealer.

Before going on a trip
First things first

  • Turn the engine off before you attempt any checks or repairs of the vehicle.
  • Be sure tires are inflated correctly. Check for damage and tire wear.
  • See that wheel bolts are properly tightened and not loose or missing.
  • Check engine oil level, add if necessary.
  • Make it a habit to have engine oil checked with every fuel filling.
  • Check coolant level to assure sufficient engine cooling.
  • Be sure you have a well charged battery.
  • Check brake fluid level. If too low, have brake system checked.
  • Replenish windshield washer fluid.
  • Check if engine hood is latched safely.
  • Replace worn or cracked wiper blades.
  • See that all windows are clear and unobstructed.
  • Keep air intake slots and area between engine hood and windshield free of snow and ice, so that the heater and the windshield wipers work properly.

NEVER invite car theft!
An unlocked car with the key in the ignition switch invites car theft. A steering wheel lock and a buzzer alarm are standard equipment in your Porsche. The buzzer will sound if you open the driver's door while the key is still in the ignition lock. It is your reminder to pull the key out of the ignition lock and to lock the doors.

Always remove the ignition key, especially if children are left unattended in the vehicle. Unsupervised use of any vehicle key may cause serious personal injury. NEVER leave your vehicle unattended with the key in the ignition lock. Take the key and lock the doors.

Keys
The vehicle is supplied with three keys fitting all locks. All keys are symmetrical so that there is no wrong way of inserting them in the locks. Two keys (a) are fitted with a battery light which is integrated in the plastic handle and lights up upon pressing the contact button. The third key (b) is flat and should be kept as an "emergency key", for instance, in your purse. After pulling the plastic head off the flat key, you can snap on a luminous plastic handle available from your Porsche dealer.

Central Locking
By means of the central locking system both doors are electrically locked or unlocked (locking button lowered or raised) when a door lock is turned with the key. Before locking, make sure that both doors are properly closed. When the doors are locked, the removable roof is also locked at the same time. If the roof is open, it is not affected by the central locking system. Both doors can be individually locked from inside by pressing the locking button. If the locking button is used to unlock one door, the second door is also automatically unlocked.

Central Locking Switch
By pressing the central locking switch (A) in the centre console it is possible with the ignition key in position 2 to lock or unlock both doors electrically. As a check, if the doors are locked, a red indicator lamp in the switch lights up. If one of the doors has been locked manually, the red indicator lamp lights up. By pressing the switch, the door is unlocked; when pressed again, both doors are locked. With the ignition key removed, locking is possible by means of the central locking switch. To unlock, the ignition must be switched on or the locking button raised.

Maintenance / Monitor Lights
The air bag system monitors the operational readiness of the igniter, sensors, warning lamp, and control electronics itself. Any malfunctions which may arise are announced by the monitor lights in the right instrument cluster. Upon activation of the vehicle ignition circuit, the "Air Bag" notation in the instrument cluster lights up for approximately 5 seconds and then goes out again, indicating system readiness. In the following cases you should immediately consult an authorized Porsche dealer in order to assure the air bag system is functioning properly:

  • Illumination of the "Air Bag" light during travel or repeated illumination longer than 5 seconds after the ignition circuit is turned on.
  • Illumination fails to light up during ignition circuit activation.

In order to ensure long-term functioning, the air bag system must be inspected by an authorized Porsche dealer after 4, 8 and 10 years from the date of manufacture shown on the safety compliance sticker, and then every 2 years.

Functioning of brake system
Your Porsche is equipped with a power assisted hydraulic dual circuit brake system with disc brakes at the front and at the rear. Both circuits function independently. One brake circuit operates the front and the other the rear axle.

In the unlikely event of hydraulic failure of one circuit, push the brake pedal down firmly and hold it in that position. A mechanical linkage activates the second circuit, and you will be able to bring the vehicle to a stop.
