Flash-to-Pass
This feature is used to signal to the
vehicle ahead that you want
to pass.
If the headlamps are off or in the
low-beam position, pull the turn
signal lever toward you to
momentarily switch to high beams.
Release the lever to turn the
high-beam headlamps off.
Daytime Running Lamps
(DRL)/Automatic
Headlamp System
DRL can make it easier for others to
see the front of your vehicle during
the day.
The DRL system makes the
low-beam headlamps come on at a
reduced brightness when the
following conditions are met:
.The ignition is in the ON/RUN
position.
. The exterior lamp control is
in AUTO.
. The engine is running. When the DRL are on, the regular
headlamps, taillamps, sidemarker,
and other lamps will not be on. The
instrument cluster will not be lit.
The headlamps automatically
change from DRL to the regular
headlamps depending on the
darkness of the surroundings. 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.
The regular headlamp system
should be turned on when needed.
Do not cover the light sensor on top
of the instrument panel because it
works with the DRL.
Delayed Headlamps
Delayed headlamps provide a
period of exterior lighting as you
leave the area around the vehicle.
This feature is activated when the
headlamps are on due to the
automatic headlamps control feature
and when the ignition is turned off.
The headlamps remain on until the
exterior lamp control is moved to the
parking lamps position or until the
pre-selected delayed headlamp
lighting period has ended.
If the ignition is turned off with the
exterior lamp control in the
;
or5position, the delayed
headlamps cycle will not occur.
To disable the delayed headlamps
feature or change the time of delay,
see Vehicle Personalization 0132.

Lighting 145
|(Hazard Warning Flasher) :
Press this button to make the front
and rear turn signal lamps flash on
and off. This warns others that you
are having trouble. Press again to
turn the flashers off.
The turn signals do not work while
the hazard warning flashers are on.
Turn and Lane-Change
Signals
Move the turn signal lever all the
way up or down to signal a turn.
An arrow on the instrument cluster
flashes in the direction of the turn or
lane change. Raise or lower the lever until the
arrow starts to flash to signal a lane
change. Hold it there until the lane
change is completed. If the lever is
briefly pressed and released, the
turn signal flashes three times.
The lever returns to its starting
position whenever it is 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 0233.
Turn Signal On Chime
If either one of the turn signals is left
on and the vehicle has been driven
more than 1.2 km (0.75 mi), a chime

166 Driving and Operating
.The Antilock Brake System
(ABS) improves vehicle stability
during hard stops, but the
brakes should be applied sooner
than when on dry pavement.
See Antilock Brake System
(ABS) 0182.
. Allow greater following distance
and watch for slippery spots. Icy
patches can occur on otherwise
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 0308. 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.
(Continued)
Warning (Continued)
.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 0178.
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.

194 Driving and Operating
display will light up in the
corresponding outside side mirror
and will flash if the turn signal is on.
{Warning
SBZA does not alert the driver to
vehicles rapidly approaching
outside of the side blind zones,
pedestrians, bicyclists,
or animals. It may not provide
alerts when changing lanes under
all driving conditions. Failure to
use proper care when changing
lanes may result in injury, death,
or vehicle damage. Before
making a lane change, always
check mirrors, glance over your
shoulder, and use the turn
signals.SBZA Detection Zones
The SBZA sensor covers a zone of
approximately one lane over from
both sides of the vehicle, or 3.5 m
(11 ft). The height of the zone is
approximately between 0.5 m (1.5 ft)
and 2 m (6 ft) off the ground. This
zone starts at approximately the
middle of the vehicle and goes back
5 m (16 ft).
How the System Works
The SBZA symbol lights up in the
side mirrors when the system
detects a moving vehicle in the next
lane over that is in the side blind
zone. This indicates it may be unsafe to change lanes. Before
making a lane change, check the
SBZA display, check mirrors, glance
over your shoulder, and use the turn
signals.
Left Side Mirror
DisplayRight Side Mirror Display
When the vehicle is started, both
outside mirror SBZA displays will
briefly come on to indicate the
system is operating. When the
vehicle is in a forward gear, the left-
or right-side mirror display will light
up if a moving vehicle is detected in
that blind zone. If the turn signal is
activated in the same direction of a
detected vehicle, this display will
flash as an extra warning not to
change lanes.

SBZA can be disabled through the
Driver Information Center (DIC). See
Driver Information Center (DIC)
0116. If SBZA is disabled by the
driver, the SBZA mirror displays will
not light up.
When the System Does Not
Seem to Work Properly
SBZA displays may not come on
when passing a vehicle quickly, for
a stopped vehicle, or when towing a
trailer. Keep in mind the SBZA
detection zones that extend back
from the side of the vehicle do not
move further back when a trailer is
towed. Use extra caution while
changing lanes when towing a
trailer. SBZA may alert you to
objects attached to the vehicle, such
as a trailer, bicycle, or object
extending out to either side of the
vehicle. This is normal system
operation; the vehicle does not need
service.
SBZA may not always alert the
driver to vehicles in the side blind
zone, especially in wet conditions.
The system does not need to be
serviced. The system may light up due to guardrails, signs, trees,
shrubs, and other non-moving
objects. This is normal system
operation; the vehicle does not need
service.
SBZA may not operate when the
SBZA sensors in the left or right
corners of the rear bumper are
covered with mud, dirt, snow, ice,
or slush, or in heavy rainstorms. For
cleaning instructions, see "Washing
the Vehicle" under
Exterior Care
0 278. If the DIC still displays the
system unavailable message after
cleaning both sides of the vehicle
toward the rear corners of the
vehicle, see your dealer.
If the SBZA displays do not light up
when vehicles are in the blind zone
and the system is clean, the system
may need service. Take the vehicle
to your dealer.
When SBZA is disabled for any
reason other than the driver turning
it off, the Side Blind Zone Alert ON
option will not be available on the
DIC menu.

Lane Departure
Warning (LDW)
If equipped, LDW may help avoid
crashes due to unintentional lane
departures. It may provide an alert if
the vehicle is crossing a lane
without using a turn signal in that
direction. LDW uses a camera
sensor to detect the lane markings
at speeds of 56 km/h (35 mph) or
greater.
{Warning
The LDW system does not steer
the vehicle. The LDW system
may not:
. Provide enough time to
avoid a crash.
. Detect lane markings under
poor weather or visibility
conditions. This can occur if

Warning (Continued)
the windshield or
headlamps are blocked by
dirt, snow, or ice; if they are
not in proper condition; or if
the sun shines directly into
the camera.
. Detect road edges.
. Detect lanes on winding or
hilly roads.
If LDW only detects lane
markings on one side of the road,
it will only warn you when
departing the lane on the side
where it has detected a lane
marking. Always keep your
attention on the road and
maintain proper vehicle position
within the lane, or vehicle
damage, injury, or death could
occur. Always keep the
windshield, headlamps, and
camera sensors clean and in
good repair. Do not use LDW in
bad weather conditions.
How the System Works
The LDW camera sensor is on the
windshield ahead of the rearview
mirror.
To turn LDW on and off, press
@on
the center stack. The control
indicator will light when LDW is on.
When LDW is on,
@is green if
LDW is available to warn of a lane
departure. If the vehicle crosses a
detected lane marking without using
the turn signal in that direction,
@
changes to amber and flashes.
Additionally, there will be three
beeps on the right or left, depending
on the lane departure direction.
When the System Does Not
Seem to Work Properly
The system may not detect lanes as
well when there are:
. Close vehicles ahead.
. Sudden lighting changes, such
as when driving through tunnels.
. Banked roads. If the LDW system is not functioning
properly when lane markings are
clearly visible, cleaning the
windshield may help.
LDW alerts may occur due to tar
marks, shadows, cracks in the road,
temporary or construction lane
markings, or other road
imperfections. This is normal system
operation; the vehicle does not need
service. Turn LDW off if these
conditions continue.
