WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause expensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle’s functions.
Many lights will illuminate when you start your vehicle to make sure the
bulb works. If any light remains on after starting the vehicle, have the
respective system inspected immediately.
Service engine soon:TheService
engine soonindicator light
illuminates when the ignition is first
turned to the ON position to check
the bulb. Solid illumination after the engine is started indicates the On
Board Diagnostics System (OBD-II) has detected a malfunction. Refer to
On board diagnostics (OBD-II)in theMaintenance and Specifications
chapter. If the light is blinking, engine misfire is occurring which could
damage your catalytic converter. Drive in a moderate fashion (avoid
heavy acceleration and deceleration) and have your vehicle serviced
immediately.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.
Check fuel cap (if equipped):
Illuminates when the fuel cap may
not be properly installed. Continued
driving with this light on may cause
the Service engine soon warning
light to come on. Refer toFuel
filler capin theMaintenance and Specificationschapter.

RADIO RECEPTION FACTORS
There are three factors that can affect radio reception:
•Distance/strength: The further you travel from an FM station, the
weaker the signal and the weaker the reception.
•Terrain: Hills, mountains, tall buildings, power lines, electric fences,
traffic lights and thunderstorms can interfere with your reception.
•Station overload: When you pass a broadcast tower, a stronger signal
may overtake a weaker one and play while the weak station frequency
is displayed.
CASSETTE/PLAYER CARE
Do:
•Use only cassettes that are 90 minutes long or less.
•Tighten very loose tapes by inserting a finger or pencil into the hole
and turning the hub.
•Remove loose labels before inserting tapes.
•Allow tapes which have been subjected to extreme heat, humidity or
cold to reach a moderate temperature before playing.
•Clean the cassette player head with a cassette cleaning cartridge after
10–12 hours of play to maintain good sound/operation.
Don’t:
•Expose tapes to direct sunlight, extreme humidity, heat or cold.
•Leave tapes in the cassette player for a long time when not being
played.
