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:
one of the low beam headlights
one of the tail lights
one of the brake lights when the brake pedal is depressed.
