fully released.
Alternator warning light
If the light comes on while the engine is running, check the tension of the alternator drive belt as soon as
possible.
NOTE: This warning light is illuminated if the alternator is not charging. However, parking brake,
brake failure and bulb failure warning lights will be illuminated at the same time due to the design of the
system.
Brake failure warning light
If the light comes on while driving and the brake pedal can be depressed further than normal, it is an
indication that one of the brake circuits is not functioning.
Stop immediately, open hood and check brake fluid level, see section "Brake fluid, power steering".
Fluid level below MIN mark: do NOT drive. Tow car to shop for check/repair of brake system.
Oil pressure warning light
If the light comes on during driving, the oil pressure is too low. Stop the car and then stop the engine
immediately. Do not drive the car.
After hard driving, the light will come on occasionally when the engine is idling. This is normal,
provided it goes off when the engine speed is increased.
Parking brake reminder light
This light will be on when the parking brake (hand brake) is applied. The parking brake lever is situated
between the front seats.
Bulb failure warning light
The light will come on if any of the following bulbs are defective:

See sections titled "Replacing bulbs" and "Fuses".
Should the warning light come on after a defective outside bulb has been replaced, the corresponding
bulb on the other side-of the car should also be replaced.
pg. 10 Warning lights, Car alarm
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.

1. Set switch (B) to ON.
2. Accelerate to desired cruise speed.
NOTE: The cruise control cannot be engaged at speeds below 22 mph (35 km/h).
3. Depress SET SPEED switch (A).
Operating brake pedal
This will automatically disengage the cruise control. Previously selected cruise speed is retained in the
memory and by momentarily setting the switch to RESUME position that speed will be re-engaged.
NOTE:
The vehicle will accelerate very quickly should there be a substantial speed differential when the switch
is reset to RESUME. It is therefore recommended that the vehicle be accelerated manually and the
switch reset to RESUME once the speed differential has been reduced.
Acceleration
Momentary acceleration, such as for passing, does not interrupt cruise control operation. The previously
selected speed will be maintained without having to set switch to RESUME.
To disengage the cruise control system:
Set switch (B) to position OFF, or depress brake pedal, or depress clutch pedal.
Switching off the starting (ignition) switch is will automatically disengage the cruise control system.
WARNING!
The cruise control should not be used in heavy traffic or when driving on wet or slippery roads.
If the gear shift is moved to Neutral while the cruise control is engaged, then depress the brake pedal
momentarily, or set the cruise control switch (B) to OFF. This will disengage the cruise control and
prevent overreving the engine.
NOTE: When driving on a grade, actual vehicle speed may vary slightly from the set cruise control
speed.
