7. Tachometer
The red segments indicate the maximum permissible
engine revolutions-per-minute (r.p.m. x 1000) for each
gear range. Ease up on the accelerator before reaching the
red area.
8. Engine Temperature Warning Light
This light will turn on and a single chime will
sound to warn of an overheated engine condi-
tion. When this light turns on, the engine tem-
perature is critically hot. The vehicle should be turned
off immediately and serviced as soon as possible. (See
page 312 for more information.)9. Anti-Lock Brake Light — If Equipped
This light monitors the Anti-Lock Brake System.
The light will turn on when the ignition switch
is turned to the ON position and may stay on for as
long as four seconds.
If the ABS light remains on or turns on while driving,
then the Anti-Lock portion of the brake system is not
functioning and service is required. However, the con-
ventional brake system will continue to operate normally
if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not turn on when the
Ignition switch is turned to the ON position, have the
light inspected by an authorized dealer. (See page 253 for

CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If temperature gauge reads (H),
pull over and stop the vehicle. Idle the vehicle with
the air conditioner turned off until the pointer drops
back into the normal range. If the pointer remains on
the “H”, and you hear continuous chimes, turn the
engine off immediately, and call for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, see Section 7 of this manual. Follow
the warnings under the Cooling System Pressure
Cap paragraph.

at calibrated speeds. This may result in a slightly differ-
ent feeling or response during normal operation in high
gear. When the vehicle speed drops, or during accelera-
tion, the clutch automatically and smoothly disengages.
NOTE:
•
The torque converter clutch will not engage until the
transmission fluid and engine coolant is warm (usu-
ally after 1–3 miles (1.6–4.8 km) of driving). Because
engine speed is higher when the torque converter
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 thetransmission. 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 transmis-
sion automatically shifts into second gear. The transmission
remains in second gear despite the forward gear selected. P
(Park), R (Reverse), and N (Neutral) will continue 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.
5 Speed Automatic Transmission
Shifting from D (Drive) to P (Park) or R (Reverse) (or
from P or R to D) should be done only after the
accelerator pedal is released and the vehicle is stopped.
Be sure to keep your foot on the brake when moving the
selector lever between these gears.
Gear Ranges
P (Park)
P (Park) supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never use P (Park) while the vehicle is in motion.
Apply the parking brake when leaving the vehicle in
this range.
When parking on a flat surface, place the gear selector in
the P (Park) position first, and then apply the parking
brake.
When parking on a hill, it is important to set the parking
brake before placing the gear selector in P (Park), other-
wise the load on the transmission locking mechanism
may make it difficult to move the selector out of park. As
an added precaution, turn the front wheels toward the
curb on a downhill grade and away from the curb on an
uphill grade.

WARNING!
On slippery road surfaces, never downshift in order
to obtain braking action. This could result in drive
wheel slip and reduced vehicle control. Your vehi-
cle’s ABS will not prevent this type of loss of control.
You could lose control of your vehicle and have an
accident.
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 transmissionwill 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

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.
