2003 Chevrolet Cavalier Owner ManualM

Turn and Lane-Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow you
to signal a turn or a lane change.
To signal a turn, move the lever all the way up or down.
When the turn is ®nished, the lever will return
automatically.
An arrow on the instrument
panel cluster will ¯ash in
the direction of the
turn or lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts to ¯ash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.
As you signal a turn or a lane change, if the arrows
¯ash rapidly, a signal bulb may be burned out and other
drivers won't see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows don't go on at all when you signal
a turn, check the fuse, see
Fuses and Circuit Breakers
on page 5-81and for burned-out bulbs.
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high or high
beam to low, pull the turn signal lever all the way
toward you. Then release it.
When the high beams are
on, this light on the
instrument panel cluster
will also be on.
Flash-to-Pass
This feature lets you use your high-beam headlamps to
signal a driver in front of you that you want to pass.
To use it, pull the turn signal/multifunction lever toward
you until the high-beam headlamps come on, then
release the lever to turn them off.
3-6

Fog Lamps
If your vehicle has this feature, use your fog lamps for
better visibility in foggy or misty conditions.
The button for your fog
lamps is located next to
the instrument panel
brightness control.
Push the top of the button to turn the fog lamps on. Push
the top of the button again to turn the fog lamps off.
When using fog lamps, the parking lamps or low-beam
headlamps must be on.
A light on the button will come on when the fog lamps
are actually on. Fog lamps will go off whenever the
high-beam headlamps come on. When the high-beam
headlamps go off, the fog lamps will come on again.
Continuous use of the fog lamps will shorten bulb
life. Limit use as necessary.
Interior Lamps
Instrument Panel Brightness
This feature controls the brightness of the instrument
panel lights.
The thumbwheel for this
feature is located on the
instrument panel to the left
of the steering column.
Turn the thumbwheel up to brighten the lights or down
to dim them. Turn the thumbwheel up all the way to
turn on the interior courtesy lamps.
3-14

Oil Pressure Light
If you have a low engine
oil pressure problem, this
light will stay on after
you start your engine, or
come on when you
are driving. This indicates
that your engine is not
receiving enough oil.
The engine could be low on oil, or could have some
other oil problem. Have it ®xed immediately.
The oil light could also come on in three other situations:
·When the ignition is on but the engine is not
running, the light will come on as a test to show you
it is working, but the light will go out when you
turn the ignition to START. If it doesn't come on with
the ignition on, you may have a problem with the
fuse or bulb. Have it ®xed right away.
·If you're idling at a stop sign, the light may blink on
and then off.
·If you make a hard stop, the light may come on for
a moment. This is normal.
{CAUTION:
Don't keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches ®re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

Before you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment. If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand to be
sure the brakes are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally to be sure that the
load is secure, and that the lamps and any trailer
brakes are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as
you would when driving your vehicle without a trailer.
This can help you avoid situations that require
heavy braking and sudden turns.
Passing
You'll need more passing distance up ahead when
you're towing a trailer. And, because you're a good deal
longer, you'll need to go much farther beyond the
passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, just move that hand
to the left. To move the trailer to the right, move your
hand to the right. Always back up slowly and, if possible,
have someone guide you.
Making Turns
Notice:Making very sharp turns while trailering
could cause the trailer to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very sharp turns while trailering.
When you're turning with a trailer, make wider turns
than normal. Do this so your trailer won't strike
soft shoulders, curbs, road signs, trees or other objects.
Avoid jerky or sudden maneuvers. Signal well in
advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal ¯asher and/or extra wiring. Check
with your dealer. The arrows on your instrument
panel will ¯ash whenever you signal a turn or lane
change. Properly hooked up, the trailer lamps will also
¯ash, telling other drivers you're about to turn,
change lanes or stop.
When towing a trailer, the arrows on your instrument
panel will ¯ash for turns even if the bulbs on the trailer
are burned out. Thus, you may think drivers behind
you are seeing your signal when they are not. It's
important to check occasionally to be sure the trailer
bulbs are still working.
