functional DRL are required on all vehicles
first sold in Canada.
The DRL system comes on in daylight when
the following conditions are met:
.The ignition is on.
.The exterior lamp control is in the AUTO
position.
.The shift lever is not in P (Park).
.The light sensor determines it is daytime.
When the DRL are on, the taillamps,

92 Lighting
The vehicle has a light sensor on the top of
the instrument panel. Do not cover the
sensor; otherwise the system will come on
whenever the ignition is on.
The system may also turn on the headlamps
when driving through a parking garage or
tunnel.
There is a delay in the transition between
the daytime and nighttime operation of the
Daytime Running Lamps (DRL) and the
automatic headlamp system so that driving
under bridges or bright overhead street
lights does not affect the system. The DRL
and automatic headlamp system are only
affected when the light sensor sees a
change in lighting lasting longer than the
delay.
If the vehicle is started in a dark garage, the
automatic headlamp system comes on
immediately. Once the vehicle leaves the
garage, it takes approximately 30 seconds
for the automatic headlamp system to
change to DRL if it is light outside. During
that delay, the instrument cluster may not
be as bright as usual. Make sure the
instrument panel brightness control is in the
full bright position. SeeInstrument Panel
Illumination Control 093. To idle the vehicle with the automatic
headlamp system off, turn the control off.
The headlamps will also stay on after
exiting the vehicle. This feature may be
programmable. See
Vehicle Personalization
0 86.
If the feature is not programmable, exit
lighting is automatic. When it is dark
enough outside, the exterior lamps remain
on for 30 seconds after the ignition is
turned off.
Lights On with Wipers
If the windshield wipers are activated in
daylight with the engine on, and the
exterior lamp control is in AUTO, the
headlamps, parking lamps, and other
exterior lamps come on. The transition time
for the lamps coming on varies based on
wiper speed. When the wipers are not
operating, these lamps turn off. Move the
exterior lamp control to
Por;to
disable this feature.

Turn and Lane-Change Signals
G:An arrow on the instrument cluster
flashes in the direction of the turn or lane
change.
To signal a turn, move the lever all the way
up or down.
To signal a lane change, raise or lower the
lever until the arrow starts to flash. The
turn signal automatically flashes three times
and if the Tow/Haul Mode is active it
flashes six times. Holding the turn signal
lever for more than one second causes the
turn signals to flash continually until the
lever is released. The lever returns to its starting position
when released.
If after signaling a turn or lane change the
arrow flashes rapidly or does not come on, a
signal bulb may be burned out.
Have any burned out bulbs replaced. If a
bulb is not burned out, check the fuse. See
Fuses and Circuit Breakers
0205.Turn Signal On Chime
If the turn signal is left on for more than
1.2 km (0.75 mi), a chime sounds at each
flash of the turn signal and the message
TURN SIGNAL ON also appears in the Driver
Information Center (DIC). To turn off the
chime and message, move the turn signal
lever to the off position.

The exterior lamps and dome lamp remain
on after the door is closed for a set amount
of time, then automatically turn off.
The exterior lamps turn off immediately by
turning the exterior lamp control off. The
exit lighting for exterior lights can be
changed. SeeVehicle Personalization 086.
Battery Load Management
The vehicle may have 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 bring
the charge back up. When the state of
charge is high, the voltage is lowered
slightly to prevent overcharging. If the
vehicle has a voltmeter gauge or a 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 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
SERVICE BATTERY CHARGING SYSTEM. If this
messages displays, it is recommended that
the driver reduce the electrical loads as
much as possible.
Battery Power Protection
This feature shuts off the interior lamps if
they are left on for more than 10 minutes
when the ignition is off. This helps to
prevent the battery from running down.
Exterior Lighting Battery Saver
The exterior lamps turn off about 10 minutes
after the ignition is turned off, if the parking
lamps or headlamps have been manually
left on. This protects against draining the
battery. To restart the 10-minute timer, turn
the exterior lamp control to the
Oposition
and then back to the
;or2position.
To keep the lamps on for more than
10 minutes, the ignition must be on or in
ACC/ACCESSORY.

Driving and Operating 131
{Warning
Snow can trap engine exhaust under the
vehicle. This may cause exhaust gases to
get inside. Engine exhaust contains
carbon monoxide (CO), which cannot be
seen or smelled. It can cause
unconsciousness and even death.
If the vehicle is stuck in snow:
.Clear snow from the base of the
vehicle, especially any blocking the
exhaust pipe.
.Open a window about 5 cm (2 in) on
the vehicle side that is away from the
wind, to bring in fresh air.
.Fully open the air outlets on or under
the instrument panel.
.Adjust the climate control system to
circulate the air inside the vehicle and
set the fan speed to the highest
setting. See“Climate Control Systems.”
For more information about CO, see
Engine Exhaust 0141. To save fuel, run the engine for short
periods to warm the vehicle and then shut
the engine off and partially close the
window. Moving about to keep warm also
helps.
If it takes time for help to arrive, when
running the engine, push the accelerator
pedal slightly so the engine runs faster than
the idle speed. This keeps the battery
charged to restart the vehicle and to signal
for help with the headlamps. Do this as
little as possible, to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the wheels to
free the vehicle when stuck in sand, mud,
ice, or snow.
If stuck too severely for the traction system
to free the vehicle, turn the traction system
off and use the rocking method. See
Traction Control/Electronic Stability Control
0
147.
{Warning
If the vehicle's tires spin at high speed,
they can explode, and you or others
could be injured. The vehicle can
overheat, causing an engine compartment
fire or other damage. Spin the wheels as
little as possible and avoid going above
56 km/h (35 mph).
Rocking the Vehicle to Get it Out
Turn the steering wheel left and right to
clear the area around the front wheels. Turn
off any traction system. Shift back and forth
between R (Reverse) and a low forward gear,
spinning the wheels as little as possible. To
prevent transmission wear, wait until the
wheels stop spinning before shifting gears.
Release the accelerator pedal while shifting,
and press lightly on the accelerator pedal
when the transmission is in gear. Slowly
spinning the wheels in the forward and
reverse directions causes a rocking motion
that could free the vehicle. If that does not
get the vehicle out after a few tries, it
might need to be towed out. If the vehicle
does need to be towed out, see Towing the
Vehicle 0240.
