Electrical Disturbances
Radio waves may pick up electrical disturbances during
transmission. They mainly affect the wave amplitude,
and thus remain a part of the AM reception. They
interfere very little with the frequency variations that
carry the FM signal.
AM Reception
AM sound is based on wave amplitude, so AM reception
can be disrupted by such things as lightning, power lines
and neon signs.
FM Reception
Because FM transmission is based on frequency varia-
tions, interference that consists of amplitude variations
can be filtered out, leaving the reception relatively clear,
which is the major feature of FM radio.
NOTE:The radio, steering wheel radio controls (if
equipped), and 6 disc CD/DVD changer (if equipped)will remain active for up to 10 minutes after the ignition
switch has been turned off. Opening a vehicle front door
will cancel this feature.

Clock Setting Procedure
The GPS receiver used in this system is synchronized to
the time data being transmitted by the GPS satellite. The
satellites’ clock is Greenwich Mean Time (GMT). This is
the worldwide standard for time. This makes the sys-
tem’s clock very accurate once the appropriate time zone
and daylight savings information is set.
To manually set the clock, change the time zone, or
change daylight savings information, use a ball point penor similar object to press the hour (H) or minute (M)
buttons on the radio. TheSetupscreen appears.
Setting the Clock
1. Press the H button on the faceplate to change the hour
or the M button on the faceplate to change the minute.
The setting will increase each time you press the button.
Holding either button in will fast forward the setting.
2. If no changes are made within 5 seconds of accessing
theSetupscreen, the screen will time out and you will be
taken to the last mode.
NOTE:To reset the clock, select the appropriate time
zone and press ENTER. The clock will revert to the
accurate time based on the time zone you selected.
Changing Time Zone
1. Highlight “Clock Setup” and press ENTER.

4. Do not use solvents such as benzine, thinner, cleaners,
or antistatic sprays.5. Store the disc in its case after playing.
6. Do not expose the disc to direct sunlight.
7. Do not store the disc where temperatures may become
too high.
RADIO OPERATION AND CELLULAR PHONES
Under certain conditions, the cellular phone being ON in
your vehicle can cause erratic or noisy performance from
your radio. This condition may be lessened or eliminated
by relocating the cellular phone antenna. This condition
is not harmful to the radio. If your radio performance
does not satisfactorily “clear” by the repositioning of the
antenna, it is recommended that the radio volume be
turned down or off during cellular phone operation.

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
CAUTION!
Long periods of engine idling, especially at high
engine speeds can cause excessive exhaust tempera-
tures which can damage your vehicle. Do not leave
your vehicle unattended with the engine running.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
Manual Transmission
Apply the parking brake, place the gearshift control lever
in N (Neutral) and depress the clutch pedal before
starting vehicle. This vehicle is equipped with a clutch
interlocking ignition system, which requires the clutch to
be fully depressed before starting the vehicle.
4WD Models Only
In 4L mode, this vehicle will start regardless of whether
or not the clutch pedal is pressed to the floor. This feature
enhances off-road performance by allowing the vehicle to
start when in 4L without having to depress the clutch
pedal. The 4 LO MODE indicator light will illuminate
when the transfer case has been shifted into this mode.
Automatic Transmission
Start the engine with the selector lever in the N (Neutral)
or P (Park) position. Apply the brake before shifting to
any driving range.

equipped with a clutch interlock safety feature. The
clutch pedal must be fully depressed to allow cranking of
the engine.
4WD Models Only — The exception to this clutch inter-
lock is 4WD models equipped with a manual transmis-
sion. For these models, the clutch interlock feature is
overridden when the vehicle is operated in 4L to enhance
off-road capability. Refer to “Starting Procedures —
Manual Transmission (4WD Models Only)” in this sec-
tion.
6-Speed Manual Transmission
WARNING!
You or others could be injured if you leave the
vehicle unattended without having the parking
brake fully applied. The parking brake should al-
ways be applied when the driver is not in the
vehicle, especially on an incline.
Follow the shift pattern on the gearshift knob.
NOTE:The backup lights will come on when your
vehicle is in R (Reverse) gear and the ignition is in the ON
position.
216 STARTING AND OPERATING

•Vehicle speed is above approximately 30 mph (48
km/h).
•Transmission has reached normal operating tempera-
ture.
When frequent transmission shifting occurs while using
Overdrive, such as when operating the vehicle under
heavy load conditions (for example, in hilly terrain,
strong head winds, or trailer towing), turning off over-
drive will improve performance and extend transmission
life by reducing excessive shifting and heat buildup.
Overdrive can be locked out by pressing the O/D OFF
button located on side of the gearshift lever. The O/D
OFF indicator light will illuminate to show that the
switch has been activated. When the indicator light is on,
Overdrive is locked out. Pressing the switch a second

Over Temperature Mode
The transmission electronics constantly monitor the
transmission oil temperature. If the transmission gets too
hot, the transmission will change the way it shifts to help
control the condition. This may result in a slightly
different feeling or response during normal operation in
D (Drive) position. If the transmission becomes hot
enough the TRANS TEMP warning light in the instru-
ment cluster will come on. After the transmission cools
down, it will return to normal operation.
Torque Converter Clutch
A feature designed to improve fuel economy has been
added to the automatic transmission of this vehicle. A
clutch within the torque converter engages automatically
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 (TCC) will not engage
until the transmission fluid and engine coolant are
warm (usually after 1–3 miles (1.6–4.8 km) of driving)
and the vehicle speed is above approximately 30 mph
(48 km/h). To understand the difference in operation,
drive the vehicle so that TCC engagement conditions
are correct, and then press and release the “O/D OFF”
button once to disengage the TCC. Wait a few seconds,
and then press and release the “O/D OFF” button
again to engage the TCC. You will notice that the
engine runs at a higher RPM when driving at vehicle
speeds above approximately 30 mph (48 km/h) with
the TCC not engaged. This is a normal condition.
•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
