2009 JEEP WRANGLER engine

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.
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.

Automatic Compass Calibration
The self-calibrating feature of the compass eliminates the
need to calibrate the compass for normal conditions.
During a short initial period, the compass may appear
erratic and the CAL symbol will appear (blinking) on the
display. After the vehicle has completed at least one
complete circle under 5 mph (8 km/h) in an area free
from large metal objects, calibration will be complete
when the CAL symbol is extinguished.
After initial calibration, the compass will continue to
automatically update this calibration whenever the ve-
hicle is in motion.
Manual Compass Calibration
NOTE: Before attempting a manual compass calibra-
tion, the engine must be running and the transmission
in the PARK position (if equipped).If the compass appears erratic or inaccurate and the
variance has been properly set, you may wish to manu-
ally recalibrate the compass. To manually calibrate the
compass:
1. First enter the variance mode. Press and hold the left
button (located on the instrument cluster) for approxi-
mately 10 seconds to enter the variance mode, and
release the button when the VAR (Compass Variance)
symbol appears.
2. The current variance value will also be displayed.
Once in the variance mode, it is necessary to release the
button, and then press and hold it again (approximately
10 seconds) until CAL is displayed (solid, not blinking).

RADIO – IF EQUIPPED
NOTE: The sales code is located on the lower right side
of the unit’s faceplate.
The REN and RER radios contain a CD/DVD player, USB
port, and a 30-gigabyte hard drive (HDD). Sirius Satellite
Radio is optional. The 6.5 in (16.5 cm) touch screen allows
for easy menu selection.
The RER radio also contains a Global Positioning System
(GPS)-based Navigation system. Refer to your uconnect
tunes (REN) or (RER) user’s
manual for detailed operating instructions.
Operating Instructions — Voice Recognition
System (VR) — If Equipped
For the radio, refer to “Voice Recognition System (VR)” in
Section 3.
Operating Instructions — uconnect phone — If
Equipped
Refer to “uconnect phone” in Section 3.
Clock Setting Procedure
uconnectgps — RER only
The GPS receiver used in this system is synchronized to
the time data being transmitted by the GPS satellite. The
satellite clock is Greenwich Mean Time (GMT). This is the
worldwide standard for time. This makes the system’s
clock very accurate once the appropriate time zone and
daylight savings information is set.

NOTE:Continuous use of the “Recirculation” mode
may make the inside air stuffy and window fogging may
occur. Extended use of this mode is not recommended.
In cold or damp weather, the use of the “Recirculation”
mode will cause windows to fog on the inside because of
moisture buildup inside the vehicle. For maximum de-
fogging, select the Outside Air position.
NOTE: The “Recirculation” mode will not operate in the
floor, mix or defrost modes.Air Conditioning
Normal Operation
Press this button to engage the air
conditioning. A light will illumi-
nate when the air conditioning
system is engaged. Once the air
conditioning is engaged, use a
combination of the mode control,
fan speed control, and tempera-
ture control to achieve your de-
sired interior temperature.
NOTE: The air conditioning compressor will not engage
until the engine has been running for about 10 seconds.

Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended. Refer to Fluids and
Genuine Parts in Section 7 for the proper coolant type.
When using the air conditioner in extremely heavy traffic
in hot weather especially when towing a trailer, addi-
tional engine cooling may be required. If this situation is
encountered, operate the transmission in a lower gear to
increase engine RPM, coolant flow and fan speed. When
stopped in heavy traffic, it may be necessary to shift intoNEUTRAL (N) and depress the accelerator slightly for
fast idle operation to increase coolant flow and fan speed.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other
obstructions.
Vacation Storage
Anytime you store your vehicle or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in the
fresh air and high blower setting. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat buildup may
cause serious injury or death.
Manual Transmission
Apply the parking brake, place the shift lever in NEU-
TRAL, and press the clutch pedal before starting the
vehicle. This vehicle is equipped with a clutch interlock-
ing ignition system. It will not start unless the clutch
pedal is pressed to the floor.
Four-Wheel Drive Models Only
In 4L mode, this vehicle will start regardless of whether
or not the clutch pedal is pressed to the floor. This featureenhances off-road performance by allowing the vehicle to
start when in 4L without having to press the clutch pedal.
The “4WD Indicator Light” will illuminate when the
transfer case has been shifted into this mode.
Automatic Transmission
Start the engine with the shift lever in the NEUTRAL or
PARK position. Apply the brake before shifting to any
driving range.
Normal Starting
NOTE:
Normal starting of either a cold or a warm
engine is obtained without pumping or pressing the
accelerator pedal.
Turn the ignition switch to the START position and
release when the engine starts. If the engine fails to start
within 10 seconds, turn the ignition switch to the LOCK
position, wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.

STARTING AND OPERATING 277

Tip Start Feature — Automatic Transmission Only
Turn the ignition switch to the START position and
release it as soon as the starter engages. The starter motor
will continue to run, but will automatically disengage
itself when the engine is running. If the engine fails to
start, the starter will disengage automatically in 10 sec-
onds. If this occurs, turn the ignition switch to the LOCK
position, wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.
Extreme Cold Weather (below –20°F or –29°C)
To ensure reliable starting at these temperatures, use of
an externally-powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
If Engine Fails to Start
WARNING!
•Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury.(Continued)
