Antilock Brake System
(ABS) Warning Light
The ABS light comes on briefly
when the engine is started.
If the light does not come on, have it
fixed so it will be ready to warn if
there is a problem.
If the ABS light stays on, turn the
ignition off. If the light comes on
while driving, stop as soon as it is
safely possible and turn the ignition
off. A chime may also sound when
the light comes on steady. Then
start the engine again to reset the
system. If the ABS light stays on,
or comes on again while driving, the
vehicle needs service. If the regular
brake system warning light is not on, the vehicle still has brakes, but
not antilock brakes. If the regular
brake system warning light is also
on, the vehicle does not have
antilock brakes and there is a
problem with the regular brakes.
See
Brake System Warning
Light 0117.

for all brake-related DIC messages.
Lane Departure Warning
(LDW) Light
For some vehicles with the Lane
Departure Warning (LDW) system,
this light comes on briefly while
starting the vehicle. If it does not
come on, have the vehicle serviced.
For vehicles with the uplevel cluster,
this light may not come on when
starting the vehicle. This light is green if LDW is on and
ready to operate.
This light changes to amber and
flashes to indicate that the lane
marking has been crossed without
using a turn signal in that direction.
See
Lane Departure Warning
(LDW) 0212.
Vehicle Ahead Indicator
If equipped, this indicator will
display green when a vehicle is
detected ahead and amber when
you are following a vehicle ahead
much too closely.

This indicator light turns on in the
instrument cluster when the
high-beam headlamps are on.
Flash-to-Pass
To flash the high beams, pull the
turn signal lever toward you, and
release.
Daytime Running
Lamps (DRL)
DRL can make it easier for others to
see the front of your vehicle during
the day. Fully functional DRL are
required on all vehicles first sold in
Canada.
The DRL system turns on the
low-beam headlamps at a reduced
brightness. If equipped with High
Intensity Discharge (HID)headlamps, the dedicated DRL will
come on when all of the following
conditions are met:
.
The ignition is on.
. The exterior lamps control is
in AUTO.
. The light sensor determines it is
daytime.
. The parking brake is released or
the vehicle is not in P (Park).
When the DRL are on, the
low-beam headlamps will be on.
The taillamps, sidemarker lamps,
instrument panel lights, and other
lamps will not be on.
The DRL turn off when the
headlamps are turned toOor the
ignition is off.
This vehicle may have a DRL
disabling function. When the DRL
are on and a turn signal is activated,
the DRL on that side will be off until
the turn signal goes off.
Automatic Headlamp
System
When the exterior lamp control is
set to AUTO and it is dark enough
outside, the headlamps come on
automatically.
There is a light sensor on top of the
instrument panel. Do not cover the
sensor; otherwise the headlamps
will come on when they are not
needed.
The system may also turn on the
headlamps when driving through a
parking garage or tunnel.
If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately. If it
is light outside when the vehicle

168 Driving and Operating
Track Events and
Competitive Driving
Racing, track testing, or competitive
driving may affect the vehicle
warranty. See the warranty manual
before using the vehicle for racing
or other competitive driving.
Caution
If the vehicle is used for track
events and competitive driving,
the engine may use more oil than
it would with normal use. Low oil
levels can damage the engine.
Check the oil level often and
maintain the proper level. See
Engine Oil0228.
For the 2.0L engine: Add and keep
the oil level at 1 L (1 qt) above the
high mark when driving under these
conditions. For information on how
to check and add oil, see Engine
Oil 0228.
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
(Continued)
Warning (Continued)
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.

than when on dry pavement.
SeeAntilock Brake System
(ABS) 0189.
. 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 0326. 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 0185.
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.
