Turn and Lane-Change Signals
An arrow on the instrument
panel cluster ashes in the
direction of the turn or
lane change.
Move the lever up or down to signal a turn.
Raise or lower the lever until the arrow starts to ash to
signal a lane change. Hold it there until the lane change is
complete.
The lever returns to its original position whenever it is
released.
If after signaling a turn or lane change the arrow ashes
rapidly or does not come on, a signal bulb may be
burned out.
Have the bulbs replaced. If the bulb is not burned out,
check the fuse. SeeTaillamps, Turn Signal, Sidemarker,
Stoplamps and Back-up Lamps on page 5-50for turn
signal bulb replacement procedures andFuses and
Circuit Breakers on page 5-99for location of fuses.
A chime will sound if the turn signal is left on for more

Daytime Running Lamps (DRL)/
Automatic Headlamp System
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving conditions,
but they can be especially helpful in the short periods
after dawn and before sunset. DRL lamps are required
to function at all times on all vehicles rst sold in Canada.
A light sensor on top of the instrument panel makes the
DRL work, so be sure it is not covered.
The DRL system will make the low-beam headlamps
come on at reduced brightness when the following
conditions are met:
The ignition is on.
The exterior lamps control is off.
The parking brake is released.
While the DRL are on, only the vehicle’s low-beam
headlamps will be on at reduced brightness. The turn
signal, taillamps, sidemarker, and other lamps will not
be on. The instrument panel will not be lit up either.
3-14

When it is dark enough outside, the DRL will turn off
and the vehicle’s headlamps and parking lamps will turn
on. The other lamps that come on with the headlamps
will also come on.
When it is bright enough outside, the headlamps will go
off and the DRL will come on.
To idle the vehicle with the DRL off, turn the exterior
lamp control off and then do one of the following:
Turn the exterior lamp control to the parking lamp
position.
Turn the exterior lamp control to the headlamp
position.
Turn the exterior lamp control from AUTO to off and
back to AUTO.
This feature is not available for vehicles rst sold in
Canada.
To turn off the automatic headlamp feature when it
is dark outside, move the exterior lamp control to the
parking lamp position. The parking lamps remain on
and the headlamps turn off. The fog lamps also go on
if they were on previously.
As with any vehicle, the regular headlamp system
should be turned on when needed.
Fog Lamps
For vehicles with fog lamps, the button is located in the
center of the exterior lamps control on the left side of
the steering column.
#:Press to turn the lamps on or off.
While the high-beam headlamps are on, the fog lamps
are off.
Some localities have laws that require the headlamps to
be on along with the fog lamps.
Exterior Lighting Battery Saver
If the parking lamps or headlamps have been left on
after the ignition has been turned to off, the exterior
lamps will turn off after about 10 minutes. This protects
the battery from being drained.
Use the exterior lamp control to turn the lamps back on,
if they are still needed.

A high electrical load occurs when several of the
following are on, such as: headlamps, high beams,
fog lamps, rear window defogger, climate control fan at
high speed, heated seats, engine cooling fans, trailer
loads, and loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s output
and the vehicle’s electrical needs. It can increase engine
idle speed to generate more power, whenever needed.
It can temporarily reduce the power demands of some
accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels of
corrective action, this action may be noticeable to the
driver. If so, a Driver Information Center (DIC) message
might be displayed, such as BATTERY SAVER ACTIVE,
BATTERY VOLTAGE LOW, or LOW BATTERY. If this
message is displayed, it is recommended that the driver
reduce the electrical loads as much as possible. SeeDIC
Warnings and Messages on page 3-56.Battery Run-Down Protection
This helps prevent the vehicle’s battery from draining
in case the interior courtesy lamps, reading lamps, trunk
lamp, underhood lamp, glove box lamps, or sun visor
vanity lamps, if equipped, are accidently left on. If any of
these lamps are left on while the ignition is off, they will
automatically turn off after 10 minutes. The lamps will not
come back on again until one of the following occurs:
The ignition is turned on.
The interior lamps control is turned off, then to
door or on.

Reduced Engine Power Light
If the reduced engine
power light is on, a chime
will sound and a noticeable
reduction in the vehicle’s
performance may occur.
If the reduced engine power light is on, but there is no
reduction in performance, proceed to your destination.
The performance may be reduced the next time the
vehicle is driven. The vehicle may be driven at a reduced
speed while the reduced engine power light is on, but
acceleration and speed may be reduced.
Anytime the reduced engine power light stays on,
the vehicle should be taken to an authorized GM
dealer/retailer as soon as possible for service.

the high-beam headlamps
are in use.
