The feature may also activate,
without airbag inflation, after an
event that exceeds a predetermined
threshold. You can lock the doors,
turn off the interior lamps, and turn
off the hazard warning flashers by
using the controls for those
features.
{Warning
A crash severe enough to inflate
the airbags may have also
damaged important functions in
the vehicle, such as the fuel
system, brake and steering
systems, etc. Even if the vehicle
appears to be drivable after a
moderate crash, there may be
concealed damage that could
make it difficult to safely operate
the vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.
In many crashes severe enough to
inflate the airbag, windshields are
broken by vehicle deformation. Additional windshield breakage may
also occur from the front outboard
passenger airbag.
.
Airbags are designed to inflate
only once. After an airbag
inflates, you will need some new
parts for the airbag system.
If you do not get them, the
airbag system will not be there
to help protect you in another
crash. A new system will include
airbag modules and possibly
other parts. The service manual
for the vehicle covers the need
to replace other parts.
. The vehicle has a crash sensing
and diagnostic module which
records information after a
crash. See Vehicle Data
Recording and Privacy 0330
and Event Data
Recorders 0331.
. Let only qualified technicians
work on the airbag systems.
Improper service can mean that
an airbag system will not work
properly. See your dealer for
service.
Passenger Sensing
System
The vehicle has a passenger
sensing system for the front
outboard passenger position. The
passenger airbag status indicator
will light on the center stack when
the vehicle is started.
The words ON and OFF will be
visible during the system check.
When the system check is
complete, either the word ON or the
word OFF will be visible. See
Passenger Airbag Status
Indicator 0106.
The passenger sensing system
turns off the front outboard
passenger frontal airbag and knee
airbag under certain conditions. No
other airbag is affected by the
passenger sensing system.

Instruments and Controls 109
The vehicle may not pass
inspection if:
.The light is on when the engine
is running.
. The light does not come on
when the ignition is in ON/RUN
with the engine not running for
Key Access or in Service Only
Mode for Keyless Access.
. Critical emission control systems
have not been completely
diagnosed. If this happens, the
vehicle would not be ready for
inspection and might require
several days of routine driving
before the system is ready for
inspection. This can happen if
the 12-volt battery has recently
been replaced or run down, or if
the vehicle has been recently
serviced.
See your dealer if the vehicle will
not pass or cannot be made ready
for the test.Brake System Warning
Light
The vehicle brake system consists
of two hydraulic circuits. If one
circuit is not working, the remaining
circuit can still work to stop the
vehicle. For normal braking
performance, both circuits need to
be working.
The brake system warning light will
come on with the electric parking
brake light when the electric parking
brake is applied. Both lights will stay
on until the electric parking brake is
released.
The brake system warning light will
also come on when there is a brake
problem.
If the warning light stays on when
the electric parking brake is not
applied, have the vehicle inspected
by your dealer right away.
MetricEnglish
This light should come on briefly
when the engine is started. If it does
not come on then, have it fixed so it
will be ready to warn you if there is
a problem.
{Warning
The brake system might not be
working properly if the brake
system warning light is on.
Driving with the brake system
warning light on can lead to a
crash. If the light is still on after
the vehicle has been pulled off
the road and carefully stopped,
have the vehicle towed for
service.
If the light comes on while driving, a
chime sounds. Pull off the road and
stop. The pedal might be harder to

Electric Parking Brake
Light
The Electric Parking Brake (EPB)
light should come on briefly as the
engine is started. If it does not come
on, have the vehicle serviced by
your dealer.
The parking brake status light
comes on when the brake is
applied. If the light continues
flashing after the parking brake is
released, or while driving, there is a
problem with the EPB system.
A message may also display in the Driver Information Center (DIC).

for more information.
The brake system warning light will
come on with the electric parking
brake light when the electric parking
brake is applied. Both lights will stay
on until the electric parking brake is
released.
If the light does not come on,
or remains flashing, see your dealer.
If this light comes on, there is a
problem with a system on the
vehicle that is causing the EPB to
work at a reduced level. The vehicle
can still be driven, but should be
taken to a dealer as soon as
possible. See Electric Parking
Brake 0201.
Antilock Brake System
(ABS) Warning Light
The Antilock Brake System (ABS)
light comes on briefly when the
engine is started.

the vehicle serviced by your dealer.
If the ABS light comes on and stays
on while driving, stop as soon as
possible and turn the ignition off.
Start the engine again to reset the
system. If the light stays on after
driving at a speed above 20 km/h
(13 mph), see your dealer for
service. A chime may also sound
when the light comes on steady.
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

Driving and Operating 181
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. Always have the
engine running and the vehicle
in gear.
. 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 0203.
. 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) 0200.
. Allow greater following distance
and watch for slippery spots. Icy
patches can occur on otherwise

188 Driving and Operating
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), continue to
firmly apply the brakes and
steer the vehicle to a safe
location.
3. Come to a complete stop. Shift to P (Park). Turn the ignition to
LOCK/OFF.
4. Set the parking brake. See Electric Parking Brake 0201.{Warning
Turning off the vehicle while
moving may cause loss of power
assist in the brake and steering
systems and disable the airbags.
While driving, only shut the
vehicle off in an emergency.
If the vehicle cannot be pulled over,
and must be shut off while driving,
turn the ignition to ACC/
ACCESSORY.
1 : This position provides power to
some of the electrical accessories.
To move the key from ACC/
ACCESSORY to LOCK/OFF, push
in the key and then turn it to
LOCK/OFF.
2 : The ignition switch stays in this
position when the engine is running.
This position can be used to operate
the electrical accessories, including
the ventilation fan and 12-volt power
outlet, as well as to display some
warning and indicator lights. This
position can also be used for
service and diagnostics, and to verify the proper operation of the
malfunction indicator lamp as may
be required for emission inspection
purposes. The transmission is also
unlocked in this position.
The battery could be drained if the
key is left in the ACC/ACCESSORY
or ON/RUN position with the engine
off. The vehicle might not start if the
battery is allowed to drain for an
extended period of time.
3 :
This position starts the engine.
When the engine starts, release the
key. The ignition switch will return to
ON/RUN for normal driving.
A warning tone sounds when the
driver door is opened if the ignition
is still in ACC/ACCESSORY and the
key is in the ignition.
If the ignition becomes difficult to
turn, see Keys026.
Key Lock Release
The vehicle is equipped with an
electronic key lock release. The key
lock release is designed to prevent
ignition key removal unless the shift
lever is in P (Park).
