Warning Lights, Gauges, and
Indicators
Warning lights and gauges can signal that
something is wrong before it becomes
serious enough to cause an expensive repair
or replacement. Paying attention to the
warning lights and gauges could prevent
injury.
Some warning lights come on briefly when
the engine is started to indicate they are
working. When one of the warning lights
comes on and stays on while driving,
or when one of the gauges shows there
may be a problem, check the section that
explains what to do. Waiting to do repairs
can be costly and even dangerous.

Instruments and Controls 83
Passenger Airbag Status Indicator
The vehicle has a passenger sensing system.
SeePassenger Sensing System 050 for
important safety information. The
instrument panel has a passenger airbag
status indicator.
United States
Canada
When the vehicle is started, the passenger
airbag status indicator will light ON and OFF,
or the symbol for on and off, for several
seconds as a system check. Then, after
several seconds, the status indicator will
light either ON or OFF, or the on or off symbol to let you know the status of the
front outboard passenger frontal airbag and
knee airbag.
If the word ON or the on symbol is lit on
the passenger airbag status indicator, it
means that the front outboard passenger
frontal airbag and knee airbag are allowed
to inflate.
If the word OFF or the off symbol is lit on
the passenger airbag status indicator, it
means that the passenger sensing system
has turned off the front outboard passenger
frontal airbag and passenger knee airbag.
If, after several seconds, both status
indicator lights remain on, or if there are no
lights at all, there may be a problem with
the lights or the passenger sensing system.
See your dealer for service.
{Warning
If the airbag readiness light ever comes
on and stays on, it means that
something may be wrong with the airbag
system. To help avoid injury to yourself
or others, have the vehicle serviced right

all accessories, such as the radio and air
conditioner.
Malfunction Indicator Lamp
(Check Engine Light)
This light is part of the vehicle’s emission
control on-board diagnostic system. If this
light is on while the engine is running, a
malfunction has been detected and the
vehicle may require service. The light should
come on to show that it is working when
the ignition is on with the engine not
running for Key Access or in Service Mode
for Keyless Access. SeeIgnition Positions
(Key Access) 0138 or
Ignition Positions (Keyless Access) 0139.
Malfunctions are often indicated by the
system before any problem is noticeable.
Being aware of the light and seeking service
promptly when it comes on may prevent
damage.
Caution
If the vehicle is driven continually with
this light on, the emission control system
may not work as well, the fuel economy
may be lower, and the vehicle may not
run smoothly. This could lead to costly
repairs that might not be covered by the
vehicle warranty.
Caution
Modifications to the engine, transmission,
exhaust, intake, or fuel system, or the
use of replacement tires that do not
meet the original tire specifications, can
cause this light to come on. This could
lead to costly repairs not covered by the
vehicle warranty. This could also affect
the vehicle’s ability to pass an Emissions
Inspection/Maintenance test. See
Accessories and Modifications 0167.
If the light is flashing : A malfunction has
been detected that could damage the
emission control system and increase vehicle
emissions. Diagnosis and service may be
required. To help prevent damage, reduce vehicle
speed and avoid hard accelerations and
uphill grades.
If the light continues to flash, find a safe
place to park. Turn the vehicle off and wait
at least 10 seconds before restarting the
engine. If the light is still flashing, follow
the previous guidelines and see your dealer
for service as soon as possible.
If the light is on steady :
A malfunction has
been detected. Diagnosis and service may be
required.
Check the following:
.If equipped with capless fuel fill: If fuel
has been added to the vehicle using the
capless funnel adapter, make sure that it
has been removed. See “Filling the Tank
with a Portable Gas Can” underFilling the
Tank (Capless Fuel Fill) 0161 or
Filling the Tank (Capped Fuel Fill) 0163.
The diagnostic system can detect if the
adapter has been left installed in the
vehicle, allowing fuel to evaporate into
the atmosphere. A few driving trips with
the adapter removed may turn off the
light.

132 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 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
Tires 0199.
.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.
.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, crash).
.Pay attention to special road signs (e.g.,
falling rocks area, winding roads, long
grades, passing or no-passing zones) and
take appropriate action.

150 Driving and Operating
2. Press the + (plus) end of the button onthe side of the shift lever to upshift,
or press the −(minus) end of the button
to downshift.
The instrument cluster will change from the
currently displayed message to the letter
“M,” for Manual position, and a number
indicating the requested gear.
While using the DSC feature, the
transmission will have firmer shifting and
sportier performance. This can be used for
sport driving or when climbing hills to stay
in gear longer or to downshift for more
power or engine braking.
The transmission will only allow you to shift
into gears appropriate for the vehicle speed
and engine revolutions per minute (rpm):
.The transmission will not allow shifting to
the next higher gear if the vehicle speed
or engine rpm is too low.
.The transmission will not allow shifting to
the next lower gear if the vehicle speed
or engine rpm is too high. Automatic Transmission Adaptation Feature
While the vehicle is being driven and gear
shifting takes place, the transmission will
learn and adapt. This increases durability
and maintains the best shift quality of the
life of the vehicle.
During vehicle break-in (initial driving), it is
normal to experience some shift bumps.
Shift quality will improve with the normal
gear shifting as the transmission learns and
adapts.
Drive Systems
All-Wheel Drive
If equipped, this feature transfers engine
power, as required, to all four wheels. It is
fully automatic, and adjusts itself as needed
for road conditions.
When using a compact spare tire on an
All-Wheel Drive (AWD) vehicle, the system
automatically detects the compact spare and
disables AWD to protect the system.
A Driver Information Center (DIC) message
will display on the instrument cluster. See
Vehicle Messages
092. To restore AWD
operation and prevent excessive wear on the system, replace the compact spare with a
full-size tire as soon as possible. See
Compact Spare Tire
0220.
AWD will be disabled and the message will
display if there is excessive wheel spin.
When the system cools down, AWD will be
restored.
Brakes
Antilock Brake System (ABS)
The Antilock Brake System (ABS) helps
prevent a braking skid and maintain steering
while braking hard.
ABS performs a system check when the
vehicle is first driven. A momentary motor
or clicking noise may be heard while this
test is going on, and the brake pedal may
move slightly. This is normal.
If there is a problem with ABS, this warning
light stays on. See Antilock Brake System
(ABS) Warning Light 086.

152 Driving and Operating
Hill Start Assist (HSA)
{Warning
Do not rely on the HSA feature. HSA does
not replace the need to pay attention
and drive safely. You may not hear or
feel alerts or warnings provided by this
system. Failure to use proper care when
driving may result in injury, death,
or vehicle damage. SeeDefensive Driving
0 129.
When the vehicle is stopped on a grade, Hill
Start Assist (HSA) temporarily prevents the
vehicle from rolling in an unintended
direction during the transition from brake
pedal release to accelerator pedal apply. The
brakes release when the accelerator pedal is
applied or automatically release after a few
seconds. The brakes may also release under
other conditions. Do not rely on HSA to hold
the vehicle.
HSA is available when the vehicle is facing
uphill in a forward gear, or when facing
downhill in R (Reverse). The vehicle must
come to a complete stop on a grade for HSA
to activate.
Ride Control Systems
Traction Control/Electronic
Stability Control
System Operation
The vehicle may have a Traction Control
System (TCS) and StabiliTrak/Electronic
Stability Control (ESC), an electronic stability
control system. These systems help limit
wheel slip and assist the driver in
maintaining control, especially on slippery
road conditions.
TCS activates if it senses that any of the
drive wheels are spinning or beginning to
lose traction. When this happens, TCS
applies the brakes to the spinning wheels
and reduces engine power to limit
wheel spin.
StabiliTrak/ESC activates when the vehicle
senses a difference between the intended
path and the direction the vehicle is actually
traveling. StabiliTrak/ESC selectively applies
braking pressure to any one of the vehicle
wheel brakes to assist the driver in keeping
the vehicle on the intended path. If cruise control is being used and traction
control or StabiliTrak/ESC begins to limit
wheel spin, cruise control will disengage.
Cruise control may be turned back on when
road conditions allow.
Both systems come on automatically when
the vehicle is started and begins to move.
The systems may be heard or felt while
they are operating or while performing
diagnostic checks. This is normal and does
not mean there is a problem with the
vehicle.
It is recommended to leave both systems on
for normal driving conditions, but it may be
necessary to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow. See
If the
Vehicle Is Stuck 0133 and “Turning the
Systems Off and On” later in this section.
The indicator light for both systems is in the
instrument cluster. This light will:
.Flash when TCS is limiting wheel spin.
.Flash when StabiliTrak/ESC is activated.
