pg. 11 Warning lights
The warning lights described on this page should never be on
when driving
When the ignition is turned on, and before the engine starts, all of the warning lights should be on to test
the function of the bulbs. Should a light not go off after the engine has started, the system indicated
should be inspected. (However, the parking brake reminder light will not go off until the parking brake
is fully released.)
G Alternator warning light (red)
If the light comes on while the engine is running, check the tension of the alternator drive belt as soon as
possible. (See section titled "Cooling system".)
NOTE: This warning light is illuminated if the alternator is not charging. However, alternator, parking
brake, brake failure, and bulb failure will be illuminated at the same time due to the design of the
system.
H Oil pressure warning light (red)
If the light comes on during driving, the oil pressure is too low. Stop the engine immediately and check
the engine oil level. See section titled "Engine Oil".
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.
M Parking brake reminder light (red)
This tight will be on when the parking brake (hand brake) is applied. The parking brake lever is situated
between the front seats.
