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.
159

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.

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 208.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.
Ultrasonic Rear Parking
Assist (URPA)
Your vehicle may be equipped with Ultrasonic Rear
Parking Assist (URPA). URPA is designed to help
you park while in REVERSE (R) and operates only
at speeds less than 3 mph (5 km/h). URPA can help
you avoid colliding with objects such as parked
vehicles. The system can detect objects 5 feet
(1.5 m) behind your vehicle and tell you how close
those objects are to your rear bumper.

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.
