Anti-lock Brake System (ABS)
The Anti-lock Braking System (ABS) is designed to improve vehicle control (i.e. stopping and steering)
during severe braking conditions by limiting wheel lock-up. When the system "senses" impending wheel
lock-up, braking pressure is automatically modulated in order to help prevent lock-up, which could lead
to a skid.
While the system is modulating braking pressure, the driver may detect a pulsation of the brake pedal.
The on/off switching of ABS modulator may also be audible. This is normal.
Please be aware that ABS does not increase the absolute braking potential of the vehicle. Thus, while
control will be enhanced, ABS will not shorten stopping distances on slippery surfaces.
Service reminder light
This light will come on at 5000 mile (8000 km) intervals. It is a reminder to the driver to have the engine
oil changed. The light will stay on for two min. after start until reset by the servicing dealer.
Car alarm
Activation
The alarm is activated either manually or automatically via a mode selector on the electronic control
unit. In AUTO mode the alarm is activated 30 sec. after the ignition has been turned off and the last door/
lid shut. It is then deactivated by inserting the key in the ignition switch and turning it to the Drive II or
Starting III position. (In the automatic mode, the alarm has a 30 second delay prior to sounding.) In
MANUAL mode the alarm is activated when the code key is placed against the sensor in the window.
An indicator light flashes when the alarm is activated.
Alarm functions
The alarm is set off at once if any door, hood or lid is opened and also by vibration. The indicator light is
lit continuously and shows that the alarm has been set off.
Deactivation
The alarm is turned off by putting the code key against the sensor in the window. The indicator light is
then turned off.
