WARNING LIGHTS AND CHIMES
Standard instrument cluster
Optional instrument cluster
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

Overdrive off:Illuminates when
the overdrive function of the
transmission has been turned off,
refer to theDrivingchapter. If the
light flashes steadily or does not illuminate, have the transmission
serviced soon, or damage may occur.
AdvanceTrac
(if equipped):
Illuminates when the AdvanceTrac

with RSC system is active. If the
light remains on, have the system
serviced immediately.
AWD lock (if equipped):
Illuminates when all wheel drive
(AWD) is locked. If the light
continues to flash, have the system
serviced.
Speed control:Illuminates when
the speed control is activated. Turns
off when the speed control system
is deactivated.
Door ajar (if equipped):
Illuminates when the ignition is in
the ON position and any door is
open.
Turn signal:Illuminates when the
left or right turn signal or the
hazard lights are turned on. If the
indicators stay on or flash faster, check for a burned out bulb.
High beams:Illuminates when the
high beam headlamps are turned on.
Key-in-ignition warning chime:Sounds when the key is left in the
ignition in the OFF/LOCK or ACCESSORY position and the driver’s door

Before returning the seatback to its original position, make sure
that cargo or any objects are not trapped underneath the
seatback. After returning the seatback to its original position, pull on
the seatback to ensure that it has fully latched. An unlatched seat may
become dangerous in the event of a sudden stop or collision.
SAFETY RESTRAINTS
Personal Safety System
The Personal Safety Systemprovides 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 Systemconsists of:
•Driver and passenger dual-stage airbag supplemental restraints.
•Front safety belts with pretensioners, energy management retractors,
and safety belt usage sensors.
•Driver’s seat position sensor.
•Front crash severity sensor.
•Restraints Control Module (RCM).
•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.
How does the Personal Safety Systemwork?
The Personal Safety Systemcan adapt the deployment strategy of your
vehicle’s safety devices according to crash severity and occupant
conditions. A collection of crash and occupant sensors provides
information to the Restraints Control Module (RCM). During a crash, the
RCM activates the safety belt pretensioners and/or either one or both
stages of the dual-stage airbag supplemental restraints based on crash
severity and occupant conditions.
The fact that the pretensioners or airbags did not activate for both front
seat occupants in a collision does not mean that something is wrong with
the system. Rather, it means the Personal Safety Systemdetermined

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 toSafety restraintssection in
this chapter.
Determining if the Personal Safety Systemis operational
The Personal Safety Systemuses a warning light in the instrument
cluster or a back-up tone to indicate the condition of the system. Refer
to theWarning lights and chimessection in theInstrument Cluster
chapter. Routine maintenance of the Personal Safety Systemis 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 the 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 Systemserviced 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.
To reduce the risk of injury, make sure children sit in the back
seat where they can be properly restrained.

STARTING
Positions of the ignition
1. OFF/LOCK, shuts off the engine
and all accessories/locks the steering
wheel, gearshift lever and allows key
removal.
2. ACC, allows the electrical
accessories such as the radio to
operate while the engine is not
running. This position also unlocks
the steering wheel.
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.
Important safety precautions
When the engine starts, the idle RPM runs faster 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 occupants buckle their safety belts. For more
information on safety belts and their proper usage, refer to theSeating
and Safety Restraintschapter.
2. Make sure the headlamps and electrical accessories are off.
•Make sure the parking brake is
set.

3. The fuel cap may not have been securely tightened. SeeFuel filler
capin this chapter.
These temporary malfunctions can be corrected by filling the fuel tank
with good quality fuel and/or properly tightening the fuel cap. After three
driving cycles without these or any other temporary malfunctions
present, theCheck engine/Service engine soonlight should turn off. (A
driving cycle consists of a cold engine startup followed by mixed
city/highway driving.) No additional vehicle service is required.
If theCheck engine/Service engine soonlight remains on, have your
vehicle serviced at the first available opportunity.
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.
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
