2003 CHEVROLET C/K bulb

2-49 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 finished, the lever will return
automatically.
An arrow on the instrument
panel cluster will flash 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 flash. 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 don't
flash but just stay on, check the turn signal flasher and
circuit breaker. See ªFuses and Circuit Breakersº in
the Index.
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 circuit breaker and for
burned
-out bulbs. (See ªFuses and Circuit Breakersº
in the Index.)
Headlamp High/Low-Beam Changer
To change the headlamps from low to high beam or high
to low beam, pull the multifunction 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.

2-88 Change Oil Light
The change oil light should
come on briefly as a bulb
check when you start the
engine. If the light doesn't
come on, have it serviced.
If the change oil soon light comes on and stays on after
you start the engine, have the oil changed.
For additional information, see ªEngine Oil, When to
Changeº in the Index. To reset the change oil light, see
ªGM Oil Life System

Low Oil Level Light
This light should come on
as a check, when you start
your engine. If the light
fails to come on, have it
repaired as soon as possible
so you will be aware when
the oil level is low.
If this light comes on and stays on, it means your engine
is low on oil. You need to check the oil level right away.

information.
