Porsche 928 S4 – Owner’s Manual

Model Year

From the “Porsche 928 S4 Owner’s Manual”, available from 928 Specialists.

NEVER invite car theft!

An unlocked car with the key in the ignition switch invites car theft.

A steering wheel lock and a gong alarm are standard equipment in your Porsche. The gong 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.

WARNING

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

Three keys are supplied with the vehicle. Each fits the ignition lock, door locks, hatchback lock, fuel filler cap lock and glove compartment lock.

There is one flat key which you can keep in your purse or wallet, for instance, as and “emergency key”. If you remove the plastic head of the flat key, you can clip on an illuminated plastic handle (available from your Porsche dealer). Vehicles with a rear seat glove compartment receive two additional keys for the compartment lock.

WARNING

NEVER remove the key from the steering lock while you are driving or as the car is rolling to a stop. The steering column will lock when you remove the key, and you will not be able to steer the car. This may result in a serious accident.

Because of the symmetrical shape of the key shaft, there is no “wrong” way of inserting the key in the locks.

The new format of the keys makes unauthorized duplication of the keys virtually impossible. This means, however, that you yourself will not be able to get replacement keys cut, unless ordered from the manufacturer.

For the lockable wheel nuts, three identical keys, are included. When taking the vehicle to your Porsche dealer or to a workshop for wheel or tire service, remember to leave one key with the service attendant.

In case of loss, duplicate wheel lock keys cannot be furnished by your Porsche dealer. Do not leave these keys in the vehicle. Keep them in a safe place.

See “Lockable wheel nuts” for details.

NOTE: it is a good idea to also keep a record of your key numbers in your wallet together with your license.

Key number

The key number of the ignition key is impressed on a plastic tag which comes with the keys. Detach this tag and keep it in a safe place.

For your protection against theft:

Record the key numbers and keep them in a safe place, such as your wallet. Do not keep them in the vehicle.

If you should lose a key, provide your Porsche dealer with the key number and the vehicle identification number to obtain a duplicate key.

Key light

Two of the keys have a built-in flashlight in the key head. The beam from a small bulb in the key head illuminates the lower part of the key stem.

The flashlight is on as long as the contact button is depressed.

The flashlight is powered by a 1.5 Volt button battery. When the beam begins to fade, replace the battery, because an old battery may leak and damage your clothes.

Use your finger nail or a small screw driver to carefully lift the key handle cover.

Insert a new, commercial available battery (1.5 V) in the contact button.

Assemble key top as shown in the figure.

Anti-theft alarm

The 3 keys supplied with vehicles equipped with an anti-theft alarm system are longer.

The alarm system is activated automatically when the doors are locked with one of these keys. When the hatchback is closed, the alarm system is not activated until the key is turned further to the left.

The alarm system is switched off automatically when a door or the hatchback is opened with the S-key. If the hatchback is opened with the alarm system is switched on, the key must be turned to the left to reactivate the alarm system.

If the driver’s or passenger side door, engine compartment hood or the hatchback is opened, or if the ignition is switched on while the alarm is activated a specially protected siren will sound for about 30 seconds. The engine cannot be started.

Keep plastic tag with key number in a safe place. Do not leave it in the vehicle.

Central door locking system

The central door locking system enables you to lock or unlock both doors simultaneously by operating one door lock.

The central door locking system functions only when both doors are fully closed. If one door is “centrally” locked before the other door is fully closed, the “centrally” locked door will unlock automatically.

The car is safely locked when locking know “A” is fully down on both doors. If locking know “A” is not fully down on one door, open that door again, close it firmly and repeat the locking operation.

On a centrally locked vehicle, the passenger door can also be unlocked and locked from inside by turning locking knob “B”. Locking knob “B” is operational only with door fully closed.

With the ignition key in Pos. “1” or “2” both doors can be locked or unlocked by pressing the central locking button in the center console. The button is illuminated when the doors are locked.

With the ignition key in Pos. “0” the central locking system is operational by turning knob “B”.

Doors

To open doors from outside, pull the recessed door handle.

To open doors from inside, pull recessed handle “C” above armrest.

The armrests have a built-in storage compartment. To open, press knob in hand cutout and tilt armrest outward. To close, tilt compartment toward door panel.

The courtesy light in the lower door panel “D” will come on when a door or the hatchback is opened. The light can also be turned on or off with the switch on the light housing.
