To Release the Steering Wheel Lock
Insert the key in the ignition and turn the wheel slightly
to the right or left to disengage the lock.
NOTE:If you turned the wheel to the right to engage
the lock, you must turn the wheel slightly to the right to
disengage it. If you turned the wheel to the left to engage
the lock, turn the wheel slightly to the left to disengage it.
SENTRY KEY IMMOBILIZER SYSTEM
The Sentry Key Immobilizer System (SKIM) prevents
unauthorized operation of the vehicle by disabling the
engine. The system will shut the engine down after 2
seconds of running if an invalid key is used to start the
vehicle. This system utilizes ignition keys which have an
electronic chip (transponder) embedded into them. Only
keys that have been programmed to the vehicle can be
used to start and operate the vehicle for longer than the
2 second validation time period.The Sentry Key Immobilizer System does not need to be
armed or activated. Operation of the system is automatic
regardless of whether or not the vehicle is locked or
unlocked. During normal operation, the “Security Alarm
System Indicator Light” will come on for 3 seconds
immediately after the ignition switch is turned on for a
bulb check. Afterwards, if the bulb remains on, this
indicates a malfunction in the electronics. If the bulb
begins to flash immediately after the ignition switch is
turned on, this indicates that an invalid key is being used
to start the vehicle. Both of these conditions will result in
the engine being shut down after 2 seconds of running.
Keep in mind that a key which has not been programmed
is also considered an invalid key even if it is cut to fit the
ignition for that vehicle.
If the “Security Alarm System Indicator Light” comes on
during normal vehicle operation (it has been running for
16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

If either light remains on and does not flash, or there is a
very fast flash rate, check for a defective outside light
bulb. If an indicator fails to light when the lever is
moved, it would suggest that the indicator bulb is
defective.
NOTE:A tone will chime if the turn signals are left on
for more than 1 mile (2 km).
Daytime Running Lights — If Equipped
The headlights come on at a low intensity level after the
vehicle has been driven approximately 3 feet (1 meter).
They will turn off when the vehicle is turned off or when
the headlights are switched on.
WINDSHIELD WIPERS AND WASHERS
CAUTION!
In cold weather, always turn off the wiper switch and
allow the wipers to return to the park position before
turning off the engine. If the wiper switch is left on
and the wipers freeze to the windshield, damage to
the wiper motor may occur when the vehicle is
restarted.
Intermittent Wiper System
Use the intermittent wiper when weather conditions
make a single wiping cycle, with a variable pause be-
tween cycles, desirable. Move the lever to the DELAY
position, then select the delay interval by turning the end
of the lever. The delay can be regulated from a maximum
of approximately 18 seconds between cycles, to a cycle
every second.

6. Front Axle Lock Indicator Light — If Equipped
Indicates when the front axle lock has been
activated.
7. Seat Belt Indicator Light
A warning chime and an indicator light will alert
you to buckle the seat belts. When the belt is
buckled, the chime will stop, but the light will stay
on until it times out (about 6 seconds).
8. Turn Signal Indicator Lights
The arrows will flash with the exterior turn signals
when the turn signal lever is operated. A tone will
chime if the turn signals are left on for more than 1 mile
(2 km).
9. Oil Pressure Warning Light
Shows low engine oil pressure. The light will come
on and remain on when the ignition switch isturned from the OFF to the ON position, and the light
will turn off after the engine is started. If the bulb does
not come on, have the system checked by your autho-
rized dealer.
If the warning light comes on and remains on while
driving, stop the vehicle and shut off the engine. DO
NOT OPERATE THE VEHICLE UNTIL THE CAUSE IS
CORRECTED. Also, a single chime will sound.
10. High Beam Indicator Light
This light shows that the headlights are on high
beam. Pull the turn signal lever towards the
steering wheel to switch the headlights from high or low.

24. Odometer/Trip Odometer
The odometer shows the total distance the vehicle has
been driven.
U.S. federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the
correct mileage that the vehicle has been driven. There-
fore, if the odometer reading is changed during repair or
replacement, be sure to keep a record of the reading
before and after the service so the correct mileage can be
determined.
25. Malfunction Indicator Light
This light is a part of an Onboard Diagnostic
System called OBD II that monitors engine, and
automatic transmission control systems. The light
will illuminate when the ignition is in the ON position
before engine start. If the bulb does not come on when
turning the key from OFF to ON, have the condition
checked promptly.Certain conditions such as a loose or missing gas cap,
poor quality fuel, etc. may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several typical driving styles. In most
situations, the vehicle will drive normally and will not
require towing.
When the engine is running, the “Malfunction Indicator
Light” may flash to alert serious conditions that could
lead to immediate loss of power or severe catalytic
converter damage. The vehicle should be serviced as
soon as possible if this occurs.
26. Electronic Stability Program (ESP) Indicator
Light/Traction Control System (TCS) Indicator Light
This indicator light starts to flash as soon as the
tires lose traction and the ESP system becomes
active. The “ESP/TCS Indicator Light” also
flashes when TCS is active. If the “ESP/TCS
Indicator Light” begins to flash during acceleration, ease

30. Electronic Throttle Control (ETC) Warning Light —
If Equipped
This light informs you of a problem with the
Electronic Throttle Control System. If a prob-
lem is detected while the engine is running, the
light will either stay on or flash depending on
the nature of the problem. Cycle the ignition key when
the vehicle is safely and completely stopped and the gear
selector is placed in the P (Park) position. The light
should turn off. If the light remains on with the engine
running, your vehicle will usually be drivable, however,
see your dealer for service as soon as possible.
If the light continues to flash when the engine is running,
immediate service is required and you may experience
reduced performance, an elevated / rough idle, or engine
stall and your vehicle may require towing. The light will
come on when the ignition is first turned on and remainon briefly as a bulb check. If the light does not come on
during starting, have the system checked by an autho-
rized dealer.
31. Compass/Mini-Trip Computer Display — If
Equipped
When the appropriate conditions exist, this display
shows the Mini-Trip Computer messages. Refer to “Mini-
Trip Computer” later in this section.

362 MAINTAINING YOUR VEHICLE

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 theignition key or start the engine. This means that your
vehicle’s OBD system isnot readyand you shouldnot
proceed to the I/M station.
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
