SENTRY KEY
The Sentry Key Immobilizer System prevents unautho-
rized vehicle operation by disabling the engine. The
system does not need to be armed or activated. Operation
is automatic, regardless of whether the vehicle is locked
or unlocked.
The system uses ignition keys that have an embedded
electronic chip (transponder) to prevent unauthorized
vehicle operation. Therefore, only keys that are pro-
grammed to the vehicle can be used to start and operate
the vehicle. The system will shut the engine off in two
seconds if someone uses an invalid key to try to start the
engine. NOTE:
A key that has not been programmed is also
considered an invalid key, even if it is cut to fit the
ignition switch lock cylinder for that vehicle.
During normal operation, after turning on the ignition
switch, the Vehicle Security Light will turn on for three
seconds for a bulb check. If the light remains on after the
bulb check, it indicates that there is a problem with the
electronics. In addition, if the Vehicle Security Light
begins to flash after the bulb check, it indicates that
someone used an invalid key to try to start the engine.
Either of these conditions will result in the engine being
shut off after two seconds.
If the Vehicle Security Light turns on during normal
vehicle operation (vehicle running for longer than 10 sec-
onds), it indicates that there is a fault in the electronics.
Should this occur, have the vehicle serviced as soon as
possible by an authorized dealer.
14 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

NOTE:
•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.
•A tone will chime if the turn signals are left on for
more than 1 mile (2 km).
Lane Change Assist
Tap the lever up or down once, without moving beyond
the detent, and the turn signal (right or left) will flash
three times then automatically turn off.
Lights-On Reminder
If the headlights or parking lights are on after the ignition
is turned OFF, a chime will sound when the driver’s door
is opened.
High/Low Beam Switch
Push the multifunction lever away from you to switch
the headlights to high beam. Pull the lever toward you to
switch the headlights back to low beam.
Flash-To-Pass
You can signal another vehicle with your headlights by
lightly pulling the multifunction lever toward the steer-
ing wheel. This will turn on the high beam headlights
until the lever is released.
Front Fog Lights — If Equipped
The front fog light switch is located on the multi-
function lever. To activate the front fog lights, turn
on the parking or low beam headlights and pull
out the end of the lever.
NOTE: The fog lights will only operate with the parking
lights or the headlights on low beam. Selecting high
beam headlights will turn off the fog lights.

INSTRUMENT CLUSTER DESCRIPTIONS
1. Fuel Gauge
The pointer shows the level of fuel in the fuel tank.
NOTE:When the ignition switch is turned to OFF, the
fuel gauge and temperature gauge may not show accu-
rate readings. When the engine is not running, turn the
ignition switch to ON to obtain accurate readings.
2. Charging System Light This light shows the status of the electrical charg-
ing system. The light should come on when the
ignition switch is first turned ON, and remain on briefly
as a bulb check. If the light stays on or comes on while
driving, turn off some of the vehicle’s non-essential
electrical devices or increase engine speed (if at idle). If
the charging system light remains on, it means that the
vehicle is experiencing a problem with the charging
system. Obtain SERVICE IMMEDIATELY. See an autho-
rized dealer. If jump starting is required, refer to “Jump Starting
Procedures” in “What To Do In Emergencies”.
3. Front Fog Light Indicator — If Equipped
This indicator will illuminate when the front fog
lights are on.
4. Low Fuel Warning Light When the fuel level reaches approximately 2.8 gal
(10.6L) this light will turn on and a single chime
will sound.
5. Speedometer
Indicates vehicle speed.
6. Front Axle Lock Indicator — If Equipped Indicates when the front axle lock has been
activated.

13. Airbag Warning LightThis light will turn on for four to eight seconds
as a bulb check when the ignition switch is first
turned ON. If the light is either not on during
starting, stays on, or turns on while driving,
then have the system inspected at an authorized dealer as
soon as possible. Refer to “Occupant Restraints” in
“Things To Know Before Starting Your Vehicle” for
further information.
14. Rear Axle Lock Indicator — If Equipped This light indicates when the rear axle lock has
been activated.
15. Tachometer
Indicates the engine speed in revolutions per minute
(RPM).

WARNING!
If a warning light remains on the system may not be
working and you will not have the benefit of ESP or
BAS. Under certain driving conditions, where ESP or
BAS would be beneficial, you - if you have not
adjusted your driving speeds and stopping in or to
account for the lack of the feature, may be in acci-
dent.
30. Electronic Throttle Control (ETC) Light This light informs you of a problem with the
Electronic Throttle Control (ETC) system. If a
problem is detected while the engine is run-
ning, 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 shift lever is placed in the PARK
position. The light should turn off. If the light remains on with the engine running, your vehicle will usually be
drivable; however, see an authorized 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 remain
on briefly as a bulb check. If the light does not come on
during starting, have the system checked by an autho-
rized dealer.
