WARNING!
A frayed or torn belt could rip apart in a collision
and leave you with no protection. Inspect the belt
system periodically, checking for cuts, frays, or loose
parts. Damaged parts must be replaced immediately.
Do not disassemble or modify the system. Seat belt
assemblies must be replaced after a collision if they
have been damaged (bent retractor, torn webbing,
etc.).
Rear Center Lap/Shoulder Belt Retractor Lock-Out
This feature is designed to lock the retractor whenever
the 60% rear seat back is not fully latched. This prevents
someone from wearing the rear center lap/shoulder belt
when the rear seat back is not fully latched.
NOTE:
•
If the rear center lap/shoulder belt cannot be pulled
out, check that the rear seat back is fully latched.
•If the rear seat back is properly latched and the rear
center lap/shoulder belt still cannot be pulled out, the
Automatic-Locking Retractor (ALR) system may beactivated. To reset this feature you must let all of the
belt webbing return into the retractor. You will not be
able to pull out more webbing until all of the webbing
has been returned back into the retractor.
WARNING!
The rear center lap/shoulder belt is equipped with a
lock-out feature to ensure that the rear seat back is in
the fully upright and locked position when occu-
pied. If the rear seat back is not fully upright and
locked and the rear center lap/shoulder belt can be
pulled out of the retractor, the vehicle should imme-
diately be taken to your dealer for service. Failure to
follow this warning could result in serious or fatal
injury.
Adjustable Upper Shoulder Belt Anchorage
In the driver and front passenger seats, the shoulder belt
can be adjusted upward or downward to position the belt
away from your neck. Push and fully depress the button
above the webbing to release the anchorage, and then
move it up or down to the position that serves you best.

engine revolutions-per-minute (r.p.m. x 1000) for each
gear range. Ease up on the accelerator before reaching the
red area.
6. Voltage Light
This light monitors the electrical system volt-
age. The light should turn on momentarily as
the engine is started. If the light stays on or turns on
while driving, it indicates a problem with the charging
system. Immediate service should be obtained.
140 UNDERSTANDING YOUR INSTRUMENT PANEL

clutch is not engaged, it may seem as if the transmis-
sion is not shifting into “Overdrive” when cold. This is
considered a normal condition. Pulling the selector
lever into the “3” position will show that the transmis-
sion is able to shift into and out of “Overdrive.”
•If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
transmission fluid partially draining from the torque
converter into the transmission. This is considered a
normal condition and it will not cause damage to the
transmission. The torque converter will refill within 5
seconds of shifting from P (Park) into any other gear
position.
Transmission Limp Home Mode
The transmission is monitored for abnormal conditions.
If a condition is detected that could cause damage, the
transmission automatically shifts into second gear. The
transmission remains in second gear despite the forward
gear selected. P (Park), R (Reverse), and N (Neutral) willcontinue to operate. This Reset feature allows the vehicle
to be driven to a dealer for service without damaging the
transmission.
If the problem has been momentary, the transmission can
be reset to regain all forward gears.
•Stop the vehicle and shift into P (Park).
•Turn the key to LOCK then start the engine.
•Shift into D (Drive) and resume driving.
NOTE:Even if the transmission can be reset, we
recommend that you visit a dealer at your earliest
possible convenience. Your dealer has diagnostic equip-
ment to determine if the problem could recur.
If the transmission cannot be reset, dealer service is
required.
218 STARTING AND OPERATING

Delayed Shifts in Cold Temperatures
During cold temperature operation, you may notice
delayed upshifts depending on engine and transmission
temperature as well as vehicle speed. This feature im-
proves warm up time of the engine and transmission to
achieve maximum efficiency.
Temporary Transmission Limp Home Mode
The transmission is monitored for abnormal conditions.
If a condition is detected that could result in transmission
damage, the transmission will engage Limp Home Mode.
If vehicle acceleration worsens, or the transmission no
longer shifts, the transmission is most likely operating in
the Limp Home Mode. In this mode, the transmission
will remain in the current gear until the vehicle is
brought to a stop. After the vehicle has stopped, P (Park),
R (Reverse), and N (Neutral) will continue to operate.
Second gear will operate in the D (Drive) shifter position.
The Malfunction Indicator Light may be illuminated.
A reset feature is available to allow the vehicle to be
driven to a dealer for service. To reset the transmission,
use the following procedure:
1. Stop the vehicle.2. Move the selector lever to the P (Park) position.
3. Turn off the engine.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Move the selector lever to the desired range. If the
problem is no longer detected, the transmission will
return to normal operation.
NOTE:Even if the transmission can be reset, we
recommend that you visit a dealer at your earliest
possible convenience. Your dealer has diagnostic equip-
ment to determine if the problem could recur.
Have the transmission checked at your authorized dealer
as soon as possible.
If the problem has been momentary, the transmission can
be reset to regain all forward gears.
Permanent Transmission Limp Home Mode
Permanent Limp Home Mode will be activated if the
transmission enters temporary Limp Home Mode three
222 STARTING AND OPERATING

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light.” It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your dealer for service as soon as
possible.CAUTION!
Prolonged driving with the “Malfunction Indicator
Light” on could cause further damage to the emis-
sion control system. It could also affect fuel economy
and driveability. The vehicle must be serviced before
any emissions tests can be performed.
If the “Malfunction Indicator Light” is flashing
while the engine is running, severe catalytic con-
verter damage and power loss will soon occur. Im-
mediate service is required.
Loose Fuel Filler Cap
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“Check Gascap” message will display in the Electronic
Vehicle Information Center (EVIC) — if equipped. If this
occurs, tighten the fuel filler cap properly and press the
odometer reset button to turn off the message. If the
problem continues, the message will appear the next time
the vehicle is started.
306 MAINTAINING YOUR VEHICLE

*Cavities 11, 12, and 13 contain self-resetting fuses
(circuit breakers) that are only serviceable by an autho-
rized dealer. The Cluster is fused by the 25 amp circuit
breaker in Cavity 11. The Passenger Seat Switch is fused
by the 25 amp circuit breaker in Cavity 12. The Door
Modules (except base), the Driver Door Lock Switch
(base), the Driver Express Power Window Switch (if
equipped), and the Passenger Door Lock Switch (base)
are fused by the 25 amp circuit breaker in Cavity 13. If
you experience temporary or permanent loss of these
systems, see your authorized dealer for service.CAUTION!
•When installing the Power Distribution Center
cover, it is important to ensure the cover is prop-
erly positioned and fully latched. Failure to do so
may allow water to get into the Power Distribu-
tion Center, and possibly result in a electrical
system failure.
•When replacing a blown fuse, it is important to
use only a fuse having the correct amperage
rating. The use of a fuse with a rating other than
indicated may result in a dangerous electrical
system overload. If a properly rated fuse contin-
ues to blow, it indicates a problem in the circuit
that must be corrected.
