Daytime Running Lamps (DRL)
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. Fully functional daytime
running lamps are required on all vehicles rst sold
in Canada.
The DRL system will make the front turn signal lamps
come on when the following conditions are met:
It is still daylight and the ignition is on,
the exterior lamp control is in the off position and
the transmission is not in PARK (P).
When DRL are on, only the front turn signal lamps will
be on. No other exterior lamps such as the parking
lamps, taillamps, etc. will be on when the DRL are being
used. Your instrument panel will not be lit up either.
When it is dark enough outside, the front turn signal
lamps will turn off and normal low-beam headlamps
will turn on.When it is bright enough outside, the regular lamps will
go off, and the front turn signal lamps will take over.
If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once you
leave the garage, it will take approximately one minute for
the automatic headlamp system to change to DRL if it is
light outside. During that delay, your instrument panel
cluster may not be as bright as usual. Make sure your
instrument panel brightness knob is in the full bright
position. SeeInstrument Panel Brightness on page 3-33
for more information.
If it is dark enough outside and the exterior lamp control
is off, a HEADLAMPS SUGGESTED message will
display on the Driver’s Information Center (DIC).
This message informs the driver that turning on the
exterior lamps is recommended. SeeDIC Warnings
and Messages on page 3-67.
Turning the exterior lamp control to off a second
time, or turning on the headlamps will remove the
HEADLAMPS SUGGESTED message in the DIC.
If the parking lamps or the fog lamps were turned on
instead, the HEADLAMPS SUGGESTED message
will continue to be displayed.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Twilight Sentinel®
Twilight Sentinel®can turn your lamps on and off for you.
A light sensor on top of the instrument panel makes the
Twilight Sentinel
®work, so be sure it is not covered.
With Twilight Sentinel
®you will see the following happen:
When it is dark enough outside, the front turn signal
lamps (DRL) will go off, and the headlamps and
parking lamps will come on. The other lamps that
come on with headlamps will also come on.
When it is bright enough outside, the headlamps will
go off, and the front turn signal lamps (DRL) will
come on, as long as the exterior lamp switch is in the
AUTO position.
If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once you
leave the garage, it will take approximately one minute for
the automatic headlamp system to change to DRL if it is
light outside. During that delay, your instrument panel
cluster may not be as bright as usual. Make sure your
instrument panel brightness control is in full bright
position. SeeInstrument Panel Brightness on page 3-33
for more information.You can idle the vehicle with the lamps off, even when
it is dark outside. After starting the vehicle, turn the
exterior lamp control band to off, then release it.
The lamps will remain off until you turn the control band
to off again.
Twilight Sentinel
®also provides exterior illumination as
you leave the vehicle. If Twilight Sentinel®has turned
on the lamps when you turn off the ignition, your lamps
will remain on until:
The exterior lamp switch is moved from OFF to the
parking lamp position, or
a delay time that you select has elapsed.
SeeDriver Information Center (DIC) on page 3-64to
select the delay time that you want. You can also select
no delay time.
If you turn off the ignition with the exterior lamp switch
in the parking lamp or headlamp position, the Twilight
Sentinel
®delay will not occur. The lamps will turn off as
soon as the switch is turned off.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Battery Run-Down Protection
Your vehicle has a feature to help prevent you from
draining the battery in case the underhood lamp, vanity
mirror lamps, cargo lamps, reading lamps, console
or glove box lamps are accidentally left on or in case
something is plugged into the accessory power outlet or
cigarette lighter. If you leave any of these lamps on,
they will automatically time-out after about 20 minutes.
To reset it, all of the above lamps must be turned
off or the ignition key must be in ON.
Head-Up Display (HUD)
{CAUTION:

your eld of view, it may take you more time to
see things you need to see when it is dark
outside. Be sure to keep the HUD image dim
and placed low in your eld of view.The Head-Up Display (HUD) allows you to see some of
the driver information that appears on your instrument
panel cluster.
The information may be displayed in English or metric

system. SeeWindshield Replacement on page 6-49.The following Adaptive Cruise Control (ACC) messages
may appear in the HUD:
CRUISE SPEED LIMITED:This message indicates that
your vehicle speed has been reduced below your set
speed due to ACC limitations. Your set speed is too high
and ACC cannot detect other vehicles at far enough
distances for the system to operate properly.
TIGHT CURVE:This message indicates that ACC has
reduced your vehicle speed due to a tight curve in
the road. Once the road straightens, ACC will return to
your selected set speed or follow distance setting.
See “Adaptive Cruise Control (ACC)” underTurn
Signal/Multifunction Lever on page 3-7for more
information.

NO FOB, OFF OR RUN?:When this message displays,
it means that the keyless access transmitter is not
detected inside the vehicle while you are trying to turn
the ignition off. Your vehicle may be near a strong
radio antenna signal causing the keyless access system
to be jammed. The vehicle will remain in ACC until off
or START has been pressed or ve minutes has
expired. If you turn the ignition off and you cannot nd
the keyless access transmitter, you will not be able
to restart the vehicle. The keyless access transmitter

the transmission is being placed in gear under conditions
that may cause damage to the vehicle’s engine,
transmission, or ability to accelerate. Reduced engine
power can affect the vehicle’s ability to accelerate. If this
message 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 this message is on, but acceleration and
speed may be reduced. Anytime this message stays on,
the vehicle should be taken to your GM dealer for service
as soon as possible.
RIGHT DOOR AJAR:The passenger’s door is open or
ajar when this message appears. The vehicle must
be running and the transmission not in PARK (P) for this
message to display. A chime will sound if the vehicle’s
speed is greater than 3 mph (5 km/h).
SERVICE A/C:This message appears when the
electronic sensors that control the air conditioning and
heating systems are no longer working. Have the climate
control system serviced by your GM dealer if you
notice a drop in heating and air conditioning efficiency.
SERVICE ABS (Anti-Lock Brake System):If the
SERVICE ABS message is displayed when you
are driving, stop as soon as possible and turn the
ignition off. Then start the engine again to reset the
