WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause extensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle’s functions.
Many lights will illuminate when you start your vehicle to make sure the
bulbs work. If any light remains on after starting the vehicle, refer to the
respective system warning light for additional information.
Check engine:TheCheck Engine
indicator light illuminates when the
ignition is first turned to the ON
position to check the bulb. Solid
illumination after the engine is started indicates the On Board
Diagnostics System (OBD-II) has detected a malfunction. Refer toOn
board diagnostics (OBD-II)in theMaintenance and Specifications
chapter. If the light is blinking, engine misfire is occurring which could
damage your catalytic converter. Drive in a moderate fashion (avoid
heavy acceleration and deceleration) and have your vehicle serviced
immediately by your authorized dealer.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.

Check fuel cap (if equipped):
Illuminates when the fuel cap may
not be properly installed. Continued
driving with this light on may cause
the Check engine warning light to
come on, refer toFuel filler capin
theMaintenance and Specificationchapter.
Brake system warning light:To
confirm the brake system warning
light is functional, it will
momentarily illuminate when the
ignition is turned to the ON position
when the engine is not running, or in a position between ON and START,
or by applying the parking brake when the ignition is turned to the ON
position. If the brake system warning light does not illuminate at this
time, seek service immediately from your authorized dealer. Illumination
after releasing the parking brake indicates low brake fluid level or a
brake system malfunction and the brake system should be inspected
immediately by your authorized dealer.
Driving a vehicle with the brake system warning light on is
dangerous. A significant decrease in braking performance may
occur. It will take you longer to stop the vehicle. Have the vehicle
checked by your authorized dealer.
Anti-lock brake system:If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately by your
authorized dealer. Normal braking is still functional unless the brake
warning light also is illuminated.
Airbag readiness:If this light fails
to illuminate when ignition is turned
to ON, continues to flash or remains
on, have the system serviced
immediately by your authorized dealer. A chime will also sound when a
malfunction in the supplemental restraint system has been detected.

An oil change is required whenever indicated by the message center and
according to the recommended maintenance schedule. USE ONLY
RECOMMENDED ENGINE OILS.

•Allow more distance for stopping with a trailer attached.
•If you are driving down a long or steep hill, shift into the “L” gear
position. Do not apply the brakes continuously, as they may overheat
and become less effective.
•The trailer tongue weight should be 10–15% of the loaded trailer
weight.
•After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park).
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
RECREATIONAL TOWING
Follow these guidelines for your specific powertrain combination to tow
your vehicle for personal travel (such as behind a recreational vehicle or
moving truck).
In case of roadside emergency with a disabled vehicle, please refer to the
Wrecker towingsection in theDrivingchapter.
These guidelines are designed to ensure that your transmission is not
damaged due to insufficient lubrication.
Front Wheel Drive (FWD) vehicles:
Do not tow your Front Wheel Drive vehicle with the front drive wheels
on the ground as transaxle damage may occur. It is recommended to tow
your vehicle with the front drive wheels on a dolly or use a car-hauling
trailer.
All Wheel Drive (AWD) vehicles:
Do not tow your All Wheel Drive vehicle with any wheels on the ground
as vehicle or transaxle damage may occur. It is recommended to tow
your vehicle using a car-hauling trailer.

Do not park, idle, or drive your vehicle in dry grass or other dry
ground cover. The emission system heats up the engine
compartment and exhaust system, which can start a fire.
Do not start your vehicle in a closed garage or in other enclosed
areas. Exhaust fumes can be toxic. Always open the garage door
before you start the engine. SeeGuarding against exhaust fumesin
this chapter for more instructions.
If you smell exhaust fumes inside your vehicle, have your dealer
inspect your vehicle immediately. Do not drive if you smell
exhaust fumes.
Important safety precautions
A computer system controls the engine’s idle revolutions per minute
(RPM). When the engine starts, the idle RPM runs higher than normal in
order to warm the engine. If the engine idle speed does not slow down
automatically, have the vehicle checked.
Before starting the vehicle:
1. Make sure all vehicle occupants have buckled their safety belts. For
more information on safety belts and their proper usage, refer to the
Seating and Safety Restraintschapter.
2. Make sure vehicle accessories are off.
•Make sure the parking brake is
set.

The Traction Controlsystem will allow your vehicle to make better use
of available traction on slippery surfaces. The system is a driver aid
which makes your vehicle easier to handle primarily on snow and ice
covered roads.
During Traction Controloperation the engine will not “rev-up” when
you push further on the accelerator. This is normal system behavior.
If you should become stuck in deep
snow or on a very slippery road
surface, try switching the Traction
Controlsystem off. This may allow
excess wheel spin to “dig” the
vehicle out or enable a successful
“rocking” maneuver.
Aggressive driving in any road conditions can cause you to lose
control of your vehicle increasing the risk of severe personal
injury or property damage. The occurrence of a Traction Control
event is an indication that at least some of the tires have exceeded
their ability to grip the road; this may lead to an increased risk of loss
of vehicle control, vehicle rollover, personal injury and death. If you
experience a severe road event, SLOW DOWN.
STEERING
To help prevent damage to the power steering system, never hold the
steering wheel at its furthest turning points (until it stops) for more than
a few seconds when the engine is running.
It is also important to maintain a proper power steering fluid level in the
power steering fluid reservoir:
•Do not operate the vehicle with a low power steering pump fluid level.
SeeChecking and adding power steering fluidin theMaintenance
and Specificationschapter.
•Some noise is normal during operation. If the noise is excessive, check
for low power steering pump fluid level before seeking service by your
authorized dealer.
•Heavy or uneven steering efforts may be caused by low power steering
pump fluid level. Check for low power steering pump fluid level before
seeking service by your authorized dealer.
•Do not fill the power steering pump reservoir above the maximum
level, as this may result in leaks from the reservoir. SeeChecking and
adding power steering fluidin theMaintenance and Specifications
chapter.

If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper steering alignment
AUTOMATIC TRANSAXLE OPERATION
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the ON position unless the brake pedal is depressed.
If you cannot move the gearshift lever out of P (Park) with ignition in
the ON position and the brake pedal depressed:
1. Remove the trim ring around the gearshift lever.
2. Remove the console panel by
opening the armrest, grasping the
panel firmly, then pulling up. This
will allow access to the gearshift
assembly.
