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
214 STARTING AND OPERATING

BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic
brake systems. If either of the two hydraulic
systems loses normal capability, the remaining
system will still function. There will be some
loss of overall braking effectiveness. This may be evident
by increased pedal travel during application, greater
pedal force required to slow or stop, and potential
activation of the Brake Warning Light.
In the event power assist is lost for any reason (for
example, repeated brake applications with the engine off)
the brakes will still function. The effort required to brake
the vehicle will be much greater than that required with
the power system operating.
Anti-Lock Brake System
The Anti-Lock Brake System provides increased vehicle
stability and brake performance under most braking
conditions. The system automatically ªpumpsº the
brakes during severe braking conditions to prevent
wheel lock-up.The electronic brake force distribution (EBD) prevents the
rear wheels from over-braking and provides greater
control of available braking forces applied to the rear
axle.
When the vehicle is driven over 7 mph (11 km/h), you
may also hear a slight clicking sound as well as some
related motor noises. These noises are the system per-
forming its self check cycle to ensure that the ABS system
is working properly. This self check occurs each time the
vehicle is started and accelerated past 7 mph (11 km/h).
ABS is activated during braking under certain road or
stopping conditions. ABS-inducing conditions can in-
clude ice, snow, gravel, bumps, railroad tracks, loose
debris, or panic stops.

WARNING!
With the ESP switched off, the enhanced vehicle
stability offered by ESP is unavailable. In an emer-
gency evasive maneuver, the ESP system will not
engage to assist in maintaining stability. The ªFull
Offº ESP mode is intended for off-highway or off-
road only.
Synchronizing ESP
The malfunction indicator light for the ESP is
combined with BAS indicator. If the power
supply is interrupted (battery disconnected or
discharged), the ESP/BAS malfunction indica-
tor light may illuminate with the engine running. If this
should occur, turn the steering wheel completely to the
left and then to the right. The ESP/BAS malfunction
indicator light should go out. However, if the light
remains on, have the ESP and BAS checked at your
authorized dealer as soon as possible.
ESP/BAS Malfunction Indicator Light and
ESP/TCS Indicator Light
The malfunction indicator light for the ESP is
combined with the BAS indicator. The yellow
ªESP/BAS Malfunction Indicator Lightº and
the yellow ªESP/TCS Indicator Lightº in the
instrument cluster both come on when the ignition
switch is turned to the ªONº position. They should go
out with the engine running.
The system will turn the ªESP/BAS Malfunction Indica-
tor Lightº on continuously while the engine running if it
detects a malfunction in either the ESP or the BAS or
both. If the light remains on after several ignition cycles,
and you have driven the vehicle several miles at speeds
greater than 30 mph (48 km/h), and the ESP is synchro-
nized (refer to Synchronizing ESP), see your authorized
dealer as soon as possible to have the problem diagnosed
and corrected.

tion 4 of this manual for details.
If the ignition key is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the Tire Pressure Monitoring Telltale
Light will no longer flash, and the9CHECK TPM SYS-
TEM9message will no longer display, and a pressure
value will display in place of the dashes.

Towing Tips
Before setting out on a trip, practice turning, stopping,
and backing the trailer in an area located away from
heavy traffic.
Towing Tips Ð Automatic Transmission
The ªDº range can be selected when towing. However, if
frequent shifting occurs while in this range, the ª3º range
should be selected.
NOTE:Using the ª3º range while operating the vehicle
under heavy operating conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat build up. This action will also
provide better engine braking.
The automatic transmission fluid and filter should be
changed if you REGULARLY tow a trailer for more than
45 minutes of continuous operation. See Schedule ªBº in
section 8 of this manual for transmission fluid change
intervals.
NOTE:Check the automatic transmission fluid level
before towing.

ONBOARD DIAGNOSTIC SYSTEM Ð 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 ªMalfunction Indicator Light.º 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 ªMalfunction Indicator
Lightº 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 ªMalfunction Indicator Lightº 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
ªCheck Gascapº message will display in the Electronic
Vehicle Information Center (EVIC) Ð 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.
292 MAINTAINING YOUR VEHICLE

A loose, improperly installed, or damaged fuel filler cap
may also turn on the Malfunction Indicator Light (MIL).
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle's emissions control system.
Failure to pass could prevent vehicle registration.
For states, which have an I/M (Inspection and
Maintenance) requirement, this check verifies the
following: the MIL (Malfunction Indicator Lamp)
is functioning and is not on when the engine is running,
and that the OBD (On Board Diagnostic) system is ready
for testing.
Normally, the OBD system will be ready. The OBD
system maynotbe ready if your vehicle was recently
serviced, if you recently had a dead battery, or a battery
replacement. If the OBD system should be determined
not ready for the I/M test, your vehicle may fail the test.Your vehicle has a simple ignition key actuated test,
which you can use prior to going to the test station. To
check if your vehicle's OBD system is ready, you must do
the following:
1. Insert your ignition key into the ignition switch.
2. Turn the ignition to the ON position, but do not crank
or start the engine.
3. If you crank or start the engine, you will have to start
this test over.
4. As soon as you turn your key to the ON position, you
will see your MIL symbol come on as part of a normal
bulb check.
5. Approximately 15 seconds later, one of two things will
happen:
a. The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn off
the ignition key or start the engine. This means that
your vehicle's OBD system isnot readyand you
shouldnotproceed to the I/M station.
MAINTAINING YOUR VEHICLE 293

b. The MIL will not flash at all and will remain fully
illuminated until you turn off the ignition key or
start the engine. This means that your vehicle's OBD
system isreadyand you can proceed to the I/M
station.
If your OBD system isnot ready,you should see your
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your
vehicle as you normally would in order for your OBD
system to update. A recheck with the above test routine
may then indicate that the system is now ready.
Regardless of whether your vehicle's OBD system is
ready or not ready, if the MIL symbol is illuminated
during normal vehicle operation, you should have your
vehicle serviced before going to the I/M station. The I/M
station can fail your vehicle because the MIL symbol is on
with the engine running.
REPLACEMENT PARTS
Use of genuine Mopartparts for normal/scheduled
maintenance and repairs is highly recommended to in-
sure the designed performance. Damage or failures
caused by the use of non-Mopartparts for maintenance
and repairs will not be covered by the manufacturer's
warranty.
DEALER SERVICE
Your dealer has the qualified service personnel, special
tools, and equipment to perform all service operations in
an expert manner. Service Manuals are available which
include detailed service information for your vehicle.
Refer to these manuals before attempting any procedure
yourself.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
