WARNING!
Leaving children in a vehicle unattended is danger-
ous for a number of reasons. A child or others could
be injured. Children should be warned not to touch
the parking brake, brake pedal or the gear selector
lever. Don’t leave the keys in the ignition. A child
could operate power windows, other controls, or
move the vehicle.
CAUTION!
An unlocked car is an invitation to thieves. Always
remove key from the ignition and lock all doors
when leaving the vehicle unattended.
Key-In-Ignition Reminder
If the driver’s door is opened when the key is in the
ignition and not turned to the ON position, a chime will
sound to remind you to remove the key.
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 SKIM indicator

“Off” position the instrument panel lighting is at the
lowest light level and may not be suitable for night
driving.
Daytime Running Lights — If Equipped
The high beam headlights come on at a low intensity
level whenever the engine is running, and the transmis-
sion is not in the P (Park) position. The lights remain on
until the ignition switch is turned OFF or the parking
brake is engaged. The headlight switch must be used for
normal night time driving.
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.
Fog Lights — If Equipped
The fog light switch is located in the multi-
function control lever. To activate the fog lights,
turn on the park/turn lights, low beam headlights,
or “Auto” headlights and pull out the end of the multi-
function control lever. A light in the instrument cluster
shows when the fog lights are on.
NOTE:Turning on the high beam headlights turns off
the fog lights.
A front fog light is a lighting device providing illumina-
tion forward of the vehicle under conditions of fog, rain,
snow, or dust. Principally, the front fog light supplements
the lower beam of a standard headlight system.
NOTE:Proper aim and adjustments of the front fog
lights should be made to prevent excessive glare for other
drivers.

INSTRUMENT CLUSTER DESCRIPTION
1. Speedometer
Indicates vehicle speed.
2. Brake Warning Light
The BRAKE warning light will come on when
the ignition is first turned on, and stay on
briefly as a bulb check. If the bulb does not
come on during starting, have the bulb re-
paired promptly. If the light stays on longer, it may be an
indication that the parking brake has not been released.
If the light remains on when the parking brake is off, it
indicates a possible brake hydraulic system malfunction
or low fluid level. In this case, the “Brake Warning Light”
will remain on until the cause is corrected. If a brake
malfunction is indicated, immediate repair is necessary
and continued operation of the vehicle in this condition is
dangerous.3. Turn Signal Indicator Light
The arrow will flash with the exterior turn signal
when the turn signal lever is operated.
If the vehicle electronics sense that the vehicle has
traveled about one mile with the turn signals on, a chime
will sound to alert you to turn the signals off. If either
indicator flashes at a rapid rate, check for a defective
outside light bulb.
4. High Beam Indicator Light
Indicates that headlights are on high beam.
5. Malfunction Indicator Light
This light is part of an onboard diagnostic system
called OBD II that monitors engine and auto-
matic transmission control systems. The light will
illuminate when the key is in the ON position before

Gear Ranges
NOTE:After selecting any gear range, wait a moment to
allow the selected gear to engage before accelerating.
This is especially important when the engine is cold. If
there is a need to restart the engine be sure to cycle the
key to the LOCK position before restarting. Transmission
gear engagement may be delayed after restarting the
engine if the key is not cycled to the LOCK position first.
P (Park)
This gear position 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. Always apply parking brake first,
then place the selector in P (Park) position.
WARNING!
Never use P (Park) position as a substitute for the
parking brake. Always apply parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.
WARNING!
It is dangerous to shift the selector lever out of P
(Park) or N (Neutral) if the engine speed is higher
than idle speed. If your foot is not firmly on the
brake pedal, the vehicle could accelerate quickly
forward or in reverse. You could lose control of the
vehicle and hit someone or something. Only shift
into gear when the engine is idling normally and
when your right foot is firmly on the brake pedal.

R (Reverse)
Use this range only after the vehicle has come to a
complete stop.
N (Neutral)
Shift into N (Neutral) when the vehicle is standing for
prolonged periods with the engine running. The engine
may be started in this range. Set the parking brake if you
must leave the vehicle.
NOTE:Towing the vehicle, coasting, or driving for any
other reason with selector lever in N (Neutral) can result
in severe transmission damage. Refer to “Recreational
Towing” in Section 5 and “Towing a Disabled Vehicle” in
Section 6 of this manual.
D (Drive)
The transmission automatically upshifts through fifth
gear. The D (Drive) position provides optimum driving
characteristics under all normal operating conditions.
Electronic Range Select (ERS)Operation
The Electronic Range Select (ERS) shift control allows
you to move the shifter left (-) or right (+) when the
shifter is in the D (Drive) position, allowing the selection
of the desired top gear. For example, if the driver shifts
the transmission into 3 (third gear), the transmission will
never shift above third gear, but can shift down to 2
(second) or 1 (first), when needed.
On vehicles equipped with 4.7L or 5.7L engines, use of
ERS (or Tow/Haul mode) also enables a additional
underdrive gear which is not normally used during
through-gear accelerations. This additional grade im-
proves vehicle performance and cooling capability when
towing a trailer on certain grades. In ERS mode (on all
transmissions), 1st through 3rd gear are underdrive gears
and 4th gear is direct drive. ERS 5th gear (Overdrive) is
the same as the normal 4th gear.

road surfaces only. Driving in the 4 LOW position on dry
hard surfaced roads may cause increased tire wear and
damage to driveline components.
When operating your vehicle in 4 LOW, the engine speed
is approximately three times that of the 4 HI position at a
given road speed. Take care not to overspeed the engine
and do not exceed 25 mph (40 km/h).
Proper operation of four wheel drive vehicles depends on
tires of equal size, type, and circumference on each
wheel. Any difference will adversely affect shifting and
cause damage to the transfer case.
Because four wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the N
(Neutral) position without first fully engaging the
parking brake. The transfer case N (Neutral) position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
regardless of the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.
Shift Positions
For additional information on the appropriate use of each
transfer case mode position, see the information below:

PARKING BRAKE
To set the parking brake, pull the lever up as firmly as
possible. When the parking brake is applied with the
ignition ON, the “Brake Warning Light” in the instru-
ment cluster will light. To release the parking brake, pull
up slightly, press the center button, then lower the lever
completely.
NOTE:The instrument cluster “Brake Warning Light”
indicates only that the parking brake is applied. It does
not indicate the degree of brake application.
Be sure the parking brake is firmly set when parked and
the gear shift lever is in the P (Park) position. When
parking on a hill, you should apply the parking brake
before placing the gear shift lever in P (Park), otherwise
the load on the transmission locking mechanism may
make it difficult to move the selector out of P (Park).

WARNING!
•Always fully apply the parking brake when leav-
ing your vehicle, or it may roll and cause damage
or injury. Also, be certain to leave the transmis-
sion in P (Park). Failure to do so may allow the
vehicle to roll and cause damage or injury.
•Leaving children in a vehicle unattended is dan-
gerous for a number of reasons. A child or others
could be injured. Children should be warned not
to touch the parking brake or the gear selector
lever. Don’t leave the keys in the ignition. A child
could operate power windows, other controls, or
move the vehicle.
•Be sure the parking brake is fully disengaged
before driving, failure to do so can lead to brake
problems due to excessive heating of the rear
brakes.
When parking on a hill, turn the front wheels toward the
curb on a downhill grade and away from the curb on an
uphill grade.
The parking brake should always be applied whenever
the driver is not in the vehicle.
ANTI-LOCK BRAKE SYSTEM
The Anti-Lock Brake System (ABS) is designed to aid the
driver in maintaining vehicle control under adverse
braking conditions. The system operates with a separate
computer to modulate hydraulic pressure to prevent
wheel lock-up and help avoid skidding on slippery
surfaces.
All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.
