INSTRUMENTS AND CONTROLS 131
Antilock Brake System
(ABS) Warning Light
This 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 light comes on while driving,
stop as soon as it is safely possible
and turn off the vehicle. 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. A chime may also sound when
the light comes on steady.
If the ABS light is the only light on,
the vehicle has regular brakes, but the
antilock brakes are not functioning.If both the ABS and the brake system
warning light are on, the vehicle's
antilock brakes are not functioning
and there is a problem with the
regular brakes. See your dealer for
service.
See
Brake System Warning Light 0129.
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)
0 219.
Lane Keep Assist (LKA)
Light
For some vehicles, 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 LKA is available
to assist.

DRIVING AND OPERATING 171
Defensive Driving
Defensive driving means“always
expect the unexpected.” The first step
in driving defensively is to wear the
seat belt. See Seat Belts068.
. Assume that other road users
(pedestrians, bicyclists, and other
drivers) are going to be careless
and make mistakes. Anticipate
what they might do and be ready.
. Allow enough following distance
between you and the driver in
front of you.
. Focus on the task of driving.
Drunk Driving
Death and injury associated with
drinking and driving is a global
tragedy.
{Warning
Drinking and then driving is very
dangerous. Your reflexes,
perceptions, attentiveness, and
(Continued)
Warning (Continued)
judgment can be affected by even a
small amount of alcohol. You can
have a serious—or even fatal —
collision if you drive after drinking.
Do not drink and drive or ride with
a driver who has been drinking.
Ride home in a cab; or if you are
with a group, designate a driver
who will not drink.
Control of a Vehicle
Braking, steering, and accelerating are
important factors in helping to control
a vehicle while driving.
Braking
Braking action involves perception
time and reaction time. Deciding to
push the brake pedal is perception
time. Actually doing it is
reaction time.
Average driver reaction time is about
three-quarters of a second. In that
time, a vehicle moving at 100 km/h (60 mph) travels 20 m (66 ft), which
could be a lot of distance in an
emergency.
Helpful braking tips to keep in mind
include:
.
Keep enough distance between
you and the vehicle in front
of you.
. Avoid needless heavy braking.
. Keep pace with traffic.
If the engine ever stops while the
vehicle is being driven, brake normally
but do not pump the brakes. Doing so
could make the pedal harder to push
down. If the engine stops, there will
be some power brake assist but it will
be used when the brake is applied.
Once the power assist is used up, it
can take longer to stop and the brake
pedal will be harder to push.
Steering
Electric Power Steering
If the vehicle has electric power
steering it does not have power
steering fluid. Regular maintenance is
not required.

DRIVING AND OPERATING 173
Off-Road Recovery
The vehicle's right wheels can drop off
the edge of a road onto the shoulder
while driving. Follow these tips:1. Ease off the accelerator and then, if there is nothing in the way,
steer the vehicle so that it
straddles the edge of the
pavement.
2. Turn the steering wheel about one-eighth of a turn, until the
right front tire contacts the
pavement edge.
3. Turn the steering wheel to go straight down the roadway.
Loss of Control
Skidding
There are three types of skids that
correspond to the vehicle's three
control systems:
.Braking Skid —wheels are not
rolling.
. Steering or Cornering Skid —too
much speed or steering in a curve
causes tires to slip and lose
cornering force.
. Acceleration Skid —too much
throttle causes the driving wheels
to spin.
Defensive drivers avoid most skids by
taking reasonable care suited to
existing conditions, and by not
overdriving those conditions. But
skids are always possible.
If the vehicle starts to slide, follow
these suggestions:
. Ease your foot off the accelerator
pedal and steer the way you want
the vehicle to go. The vehicle may
straighten out. Be ready for a
second skid if it occurs. .
Slow down and adjust your driving
according to weather conditions.
Stopping distance can be longer
and vehicle control can be affected
when traction is reduced by water,
snow, ice, gravel, or other material
on the road. Learn to recognize
warning clues —such as enough
water, ice, or packed snow on the
road to make a mirrored surface
— and slow down when you have
any doubt.
. Try to avoid sudden steering,
acceleration, or braking, including
reducing vehicle speed by shifting
to a lower gear. Any sudden
changes could cause the tires to
slide.
Remember: Antilock brakes help avoid
only the braking skid.
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.

174 DRIVING AND OPERATING
{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 enoughand 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 Tires0267.
. Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving on
flat or rolling terrain. Tips include:
.Keep the vehicle serviced and in
good shape. .
Check all fluid levels and brakes,
tires, cooling system, and
transmission.
. Shift to a lower gear when going
down steep or long hills.
{Warning
Using the brakes to slow the vehicle
on a long downhill slope can cause
brake overheating, can reduce brake
performance, and could result in a
loss of braking. Shift the
transmission to a lower gear to let
the engine assist the brakes on a
steep downhill slope.
{Warning
Coasting downhill in N (Neutral) or
with the ignition off is dangerous.
This can cause overheating of the
brakes and loss of steering assist.
Always have the engine running
and the vehicle in gear.

DRIVING AND OPERATING 175
.Drive at speeds that keep the
vehicle in its own lane. Do not
swing wide or cross the
center line.
. Be alert on top of hills; something
could be in your lane (e.g., stalled
car, accident).
. Pay attention to special road signs
(e.g., falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires and the
road creates less traction or grip, so
drive carefully. Wet ice can occur at
about 0 °C (32 °F) when freezing rain
begins to fall. Avoid driving on wet ice
or in freezing rain until roads can be
treated.
For Slippery Road Driving:
.Accelerate gently. Accelerating too
quickly causes the wheels to spin
and makes the surface under the
tires slick. .
Turn on Traction Control. See
Traction Control/Electronic Stability
Control 0193.
. 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) 0191.
. 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
Stay with the vehicle unless there is
help nearby. If possible, use Roadside
Assistance. See Roadside Service 0338.
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 the

breaking-in guideline every
time you get new brake
linings.
Following break-in, engine speed
and load can be gradually
increased.
Ignition Positions
The vehicle has an electronic keyless
ignition with pushbutton start. The Remote Keyless Entry (RKE)
transmitter must be in the vehicle for
the system to operate. If the
pushbutton start is not working, the
vehicle may be near a strong radio
antenna signal causing interference to
the Keyless Access system. See
Remote
Keyless Entry (RKE) System Operation
0 28.
To shift out of P (Park), the vehicle
must be on and the brake pedal must
be applied.
Stopping the Engine/OFF (No
Indicator Lights) : When the vehicle
is stopped, press ENGINE START/
STOP once to turn the engine off.
If the vehicle is in P (Park), the
ignition will turn off, and Retained
Accessory Power (RAP) will remain
active. See Retained Accessory Power
(RAP) 0185.
If the vehicle is not in P (Park), the
ignition will return to ACC/
ACCESSORY and display the message
SHIFT TO PARK in the Driver
Information Center (DIC). When the
vehicle is shifted into P (Park), the
ignition will turn off. Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake and
steering systems and disable the
airbags.
If the vehicle must be shut off in an
emergency:
1. Brake using a firm and steady pressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the
vehicle is moving. After shifting
to N (Neutral), firmly apply the
brakes and steer the vehicle to a
safe location.
3. Come to a complete stop, shift to P (Park), and turn the
ignition off.
4. Set the parking brake. See Electric Parking Brake 0191.
