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.

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
If your vehicle has fog
lamps, the button is
located in the center of the
exterior lamps control
on the left side of
the steering column.
Press the fog lamps button 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.

Overhead Console Reading Lamps
Your vehicle may have reading lamps located on
the overhead console. Press the lens to turn them on
and off.
Rear Assist Handle Reading Lamps
Your vehicle may have reading lamps located near
the rear assist handles. Press the lens to turn them on
and off.
Electric Power Management
The vehicle has Electric Power Management (EPM) that
estimates the battery’s temperature and state of
charge. It then adjusts the voltage for best performance
and extended life of the battery.
When the battery’s state of charge is low, the voltage is
raised slightly to quickly put the charge back in. When the
state of charge is high, the voltage is lowered slightly to
prevent overcharging. If the vehicle has a voltmeter gage
or voltage display on the Driver Information Center (DIC),
you may see the voltage move up or down. This is
normal. If there is a problem, an alert will be displayed.The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles. This is
because the generator (alternator) may not be
spinning fast enough at idle to produce all the power
that is needed for very high electrical loads.
A high electrical load occurs when several of the
following loads are on: 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, the Driver Information Center (DIC)
message might display Battery Saver Active. If this
message is displayed, it is recommended that the driver
reduce the electrical loads as much as possible. See
DIC Warnings and Messages on page 3-58.

Cruise Control Light
This light comes on
whenever you set the
cruise control.
The light goes out when the cruise control is turned off.
SeeCruise Control on page 3-10for more information.
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 as
soon as possible for service.
Highbeam On Light
This light comes on when
the high-beam headlamps
are in use.
SeeHeadlamp High/Low-Beam Changer on page 3-8
for more information.
