WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause expensive 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
bulb works. If any light remains on after starting the vehicle, have the
respective system inspected immediately.
Service engine soon:TheService
engine soonindicator 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 to
On 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.
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.

SAFETY RESTRAINTS
Personal Safety System
The Personal Safety System provides an improved overall level of frontal
crash protection to front seat occupants and is designed to help further
reduce the risk of airbag-related injuries. The system is able to analyze
different occupant conditions and crash severity before activating the
appropriate safety devices to help better protect a range of occupants in
a variety of frontal crash situations.
Your vehicle’s Personal Safety System consists of the following items:
•Driver and passenger dual-stage airbag supplemental restraints
•Driver and front passenger side airbags
•Front safety belts with pretensioners, energy management retractors,
and safety belt usage sensors
•Driver’s seat position sensor
•Front passenger sensing system
•Front crash severity sensor
•Restraints Control Module (RCM) with impact and safing sensors
•Restraint system warning light and back-up tone
•The electrical wiring for the airbags, crash sensor(s), safety belt
pretensioners, front safety belt usage sensors, driver seat position
sensor, and indicator lights

Seating and Safety Restraints

Front safety belt pretensioners
The safety belt pretensioners at the front outboard seating positions are
designed to tighten the safety belts firmly against the occupant’s body
during a frontal or near-frontal collision. This maximizes the effectiveness
of the safety belts and helps properly position the occupant relative to
the airbag to improve protection. The safety belt pretensioners can be
either activated alone or, if the collision is of sufficient severity, together
with the airbags.
Front safety belt energy management retractors
The front outboard safety belt energy management retractors allow
webbing to be pulled out of the retractor in a gradual and controlled
manner in response to the occupant’s forward momentum. This helps
reduce the risk of force-related injuries to the occupant’s chest by
limiting the load on the occupant. Refer toEnergy management feature
section in this chapter.
Determining if the Personal Safety System is operational
The Personal Safety System uses a warning light in the instrument
cluster or a back-up tone to indicate the condition of the system. Refer
to theWarning lightsection in theInstrument clusterchapter. Routine
maintenance of the Personal Safety System is not required.
The Restraints control module (RCM) monitors its own internal circuits
and the circuits for the airbag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, and the driver
seat position sensor. In addition, the RCM also monitors the restraints
warning light in the instrument cluster. A difficulty with the system is
indicated by one or more of the following.
•The warning light will either flash or stay lit.
•The warning light will not illuminate immediately after ignition is
turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and warning light are repaired.
If any of these things happen, even intermittently, have the Personal
Safety System serviced at your dealership or by a qualified technician
immediately. Unless serviced, the system may not function properly in
the event of a collision.
Safety restraints precautions
Always drive and ride with your seatback upright and the lap
belt snug and low across the hips.

STARTING
Positions of the ignition
1. OFF/LOCK, shuts off the engine
and all accessories/locks the
gearshift lever and allows key
removal.
2. ACC, allows the electrical
accessories such as the radio to
operate while the engine is not
running.
3. ON, all electrical circuits
operational. Warning lights
illuminated. Key position when driving.
4. START, cranks the engine. Release the key as soon as the engine
starts.
Refer to theSecurilockpassive anti-theft systemsection in the
Locks and Securitychapter for information on Securilockkeys.
Preparing to start your vehicle
Engine starting is controlled by the powertrain control system. This
system meets all Canadian Interference-Causing Equipment standard
requirements regulating the impulse electrical field strength of radio
noise.
When starting a fuel-injected engine, avoid pressing the accelerator
before or during starting. Only use the accelerator when you have
difficulty starting the engine. For more information on starting the
vehicle, refer toStarting the enginein this chapter.
Extended idling at high engine speeds can produce very high
temperatures in the engine and exhaust system, creating the risk
of fire or other damage.
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.

TRACTION CONTROL
For Traction Controlwarning lights refer toWarning Lightsin the
Instrument clusterchapter.
Your vehicle is equipped with a Traction Controlsystem (except on
commercial conversion packages). This system helps you maintain the
stability and steerability of your vehicle, especially on slippery road
surfaces such as snow- or ice-covered roads and gravel roads. The
system will allow your vehicle to make better use of available traction in
these conditions.
During Traction Controloperation, you may hear an electric motor
type of sound coming from the engine compartment and the engine will
not “rev-up” when you push further on the accelerator. This is normal
system behavior and should be no reason for concern.
The Traction Controlswitch,
located on the left side of the
instrument panel, allows the driver
to enable and disable the system.
The Traction Controlsystem will
automatically turn on every time the
ignition is turned OFF and RUN.
If you should become stuck in snow
or ice or on a very slippery road surface, try switching the Traction
Controlsystem off. This may allow excess wheel spin to “dig” the
vehicle out and enable a successful “rocking” maneuver.

Readiness for Inspection/Maintenance (I/M) testing
In some localities, it may be a legal requirement to pass an I/M test of
the on-board diagnostics system. If yourCheck engine/Service engine
soonlight is on, refer to the description in theWarning lights and
chimessection of theInstrument Clusterchapter. Your vehicle may not
pass the I/M test with theCheck engine/Service engine soonlight on.
If the vehicle’s powertrain system or its battery has just been serviced,
the on-board diagnostics system is reset to a “not ready for I/M test”
condition. To ready the on-board diagnostics system for I/M testing, a
minimum of 30 minutes of city and highway driving is necessary as
described below:
•First, at least 10 minutes of driving on an expressway or highway.
•Next, at least 20 minutes driving in stop-and-go, city-type traffic with
at least four idle periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete.
CHECKING AND ADDING POWER STEERING FLUID
Check the power steering fluid.
Refer to the scheduled maintenance
guide for the service interval
schedules.If adding fluid is
necessary, use only MERCON
AT F.
1. Start the engine and let it run until it reaches normal operating
temperature (the engine coolant temperature gauge indicator will be
near the center of the normal area between H and C).
2. While the engine idles, turn the steering wheel left and right several
times.
3. Turn the engine off.
