Exterior Lamps Off
Reminder
A warning chime will sound if the
exterior lamp control is left on in
either the headlamp or parking lamp
position and the driver door is
opened with the ignition off.
Headlamp High/
Low-Beam Changer
Push the turn signal lever away
from you and release to turn the
high beams on. To return to low
beams, push the lever again or pull
it toward you and release.
This indicator light turns on in the
instrument cluster when the
high-beam headlamps are on.
Flash-to-Pass
To use the flash-to-pass feature,
briefly pull the turn signal lever
toward you. The high-beam
indicator flashes to indicate to the
other driver that you intend to pass.
Daytime Running
Lamps (DRL)
DRL can make it easier for others to
see the front of your vehicle during
the day. DRL are required on all
vehicles first sold in Canada.
The DRL system makes the
dedicated 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 AUTO position.
. The transmission is not in
P (Park) or the parking brake
is off.
When DRL are on, only the front
lamps will be on. The parking
lamps, taillamps, instrument panel lights, or other exterior lamps will
not be on when the DRL are
being used.
When it is dark enough outside, the
front lamps dim to parking lamps
and the normal low-beam
headlamps turn on.
When it is bright enough outside,
the regular lamps go off, and the
front DRL will take over. 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 one minute 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 knob is in the full
bright position. See
Instrument
Panel Illumination Control 0139.
If it is dark enough outside and the
exterior lamp control is off, a Driver
Information Center (DIC) message
may display.

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 will
come on. The time it takes for the
lamps to turn on depends on the
wiper speed. When the wipers are
turned off, the lamps turn off. To
disable, move the exterior lamp
control to
Oor;.
Hazard Warning Flashers
The hazard warning flashers warn
others that you have a problem. The
button is near the center of the
instrument panel.
|:Press to make the front and
rear turn signal lamps flash on and
off. Press again to turn the
flashers off.
The hazard warning flashers work
no matter what mode the ignition is
in, even if the ignition is turned off.
When the hazard warning flashers
are on, the turn signals will
not work.
Turn and Lane-Change
Signals
An arrow on the instrument cluster
flashes in the direction of the turn or
lane change.
Move the lever all the way up or
down to signal a turn.
Raise or lower the lever until the
arrow starts to flash to signal a lane
change. Hold it there until the lane

9. Install the caliper (1) with thetwo fasteners (2). Torque to
220 Y (162 lb ft).
10. Repeat the procedure for the opposite side of the vehicle.
11. Reinstall the wheels using the specified lug nut torque. Refer
to the procedure in the vehicle
service manual.
12. After a track event, repeat the steps to reinstall the original
splash shield.
Driving on Wet Roads
Rain and wet roads can reduce
vehicle traction and affect your
ability to stop and accelerate.
Always drive slower in these types
of driving conditions and avoid
driving through large puddles and
deep-standing or flowing water.
{Warning
Wet brakes can cause crashes.
They might not work as well in a
quick stop and could cause
pulling to one side. You could
lose control of the vehicle.
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause the
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be
very cautious about trying to drive
through flowing water.
Hydroplaning
Hydroplaning is dangerous. Water
can build up under the vehicle's
tires so they actually ride on the
water. This can happen if the road is wet enough and you are going fast
enough. When the vehicle is
hydroplaning, it has little or no
contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.
Allow extra following distance.
. Pass with caution.
. Keep windshield wiping
equipment in good shape.
. Keep the windshield washer fluid
reservoir filled.
. Have good tires with proper
tread depth. See Tires0254.
. Turn off cruise control.

clear roads in shaded areas.
The surface of a curve or an
overpass can remain icy when
the surrounding roads are clear.
Avoid sudden steering
maneuvers and braking while
on ice.
. Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place and
signal for help. Stay with the vehicle
unless there is help nearby.
If possible, use Roadside
Assistance. See Roadside
Assistance Program 0320. To get
help and keep everyone in the
vehicle safe:
. Turn on the hazard warning
flashers.
. Tie a red cloth to an outside
mirror.
{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
(Continued)
Warning (Continued)
the fan speed to the highest
setting. See“Climate
Control Systems.”
For more information about CO,
see Engine Exhaust 0181.
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.

170 Driving and Operating
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. SeeTraction
Control/Electronic Stability Control
0 192.
{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 0287.
Vehicle Load Limits
It is very important to know how
much weight the vehicle can
carry. This weight is called the
vehicle capacity weight and
includes the weight of all
occupants, cargo, and all
nonfactory-installed options.
Two labels on the vehicle may
show how much weight it may properly carry: the Tire and
Loading Information label and
the Certification label.
{Warning
Do not load the vehicle any
heavier than the Gross
Vehicle Weight Rating
(GVWR), or either the
maximum front or rear Gross
Axle Weight Rating (GAWR).
This can cause systems to
break and change the way the
vehicle handles. This could
cause loss of control and a
crash. Overloading can also
reduce stopping distance,
damage the tires, and shorten
the life of the vehicle.
