Description

The car is equipped with the following devices to prevent inadvertent shifting:

Key cylinder with interlocked ignition key (Key Interlock System)

Shift lever with shift lock (Shift Lock System)

Key Interlock System:

When the shift lever is in any other position than or is not securely locked in (parking pin switch is ON), a solenoid is

activated, making it impossible to remove the ignition key from the ignition switch.

To be able to remove the key, the shift lever must be in and must be securely locked in this position (parking pin switch

must be turned off by the lock pin).

Description (cont'd)

Shift Lock System:

The shift lock system prevents the shift lever from moving to another position than [P] unless you step on the brake pedal

and the accelerator is in its rest position.

NOTE:

The shift lever cannot be shifted when the brake pedal and the accelerator are depressed at the same time.

In case of system malfunction, the shift lever can be released by pushing a key into the release slot near the shift lever.
