engine JEEP WRANGLER 2006 TJ / 2.G User Guide

NOTE:When driving uphill, at elevations above 2,000
ft. (610 meters), or when the vehicle is heavily loaded
(especially when towing) the vehicle may slow below the
SET speed. (If the vehicle speed drops below 35 mph (56
km/h), the Speed Control will automatically disengage).
If this happens, you can push down on the accelerator
pedal to maintain the desired speed.
WARNING!
Leaving the Speed Control on when not in use is
dangerous. You could accidentally set the system or
cause it to go faster than you want. You could lose
control and have an accident. Always turn the system
off when you are not using it.
ELECTRICAL POWER OUTLET
To the right of the cigar lighter (if equipped) is the 12 volt
power outlet. The outlet is connected directly to the
battery, items plugged into this outlet may discharge the
battery and/or prevent engine starting. The outlet in-
cludes a tethered cap labeled with a battery symbol
indicating the power source.

Electrical Outlet Use With Engine Off
WARNING!
•Many accessories that can be plugged in draw power
from the vehicle’s battery, even when not in use (i.e.
cellular phones, etc.). Eventually, if plugged in long
enough, the vehicle’s battery will discharge sufficiently
to degrade battery life and/or prevent engine starting.
•Accessories that draw higher power (i.e. coolers,
vacuum cleaners, lights, etc.), will degrade the battery
even more quickly. Only use these intermittently and
with greater caution.
•After the use of high power draw accessories, or long
periods of the vehicle not being started (with accesso-
ries still plugged in), the vehicle must be driven a
sufficient length of time to allow the alternator to
recharge the vehicle’s battery.
•Power outlets are designed for accessory plugs only.
Do not hang any type of accessory or accessory bracket
from the plug.
CUP HOLDERS
In the center console there are two cup holders for the
front seat passengers.
NOTE: The cup holder insert is removable from the
console, for cleaning.

Rear Window Defogger
To turn the rear window defogger on, press the
rocker switch. If you press the switch a second
time, you will turn the defogger off. A light on the rocker
switch will indicate the defogger is on. The defogger will automatically turn off after about ten
minutes. For five more minutes of operation, depress the
top of the switch to turn the defogger on again. To
prevent excessive battery drain use the defogger only
when the engine is operating.
CAUTION!
Use care when washing the inside of the rear win-
dow to prevent damage to heating elements. Use a
soft cloth and a mild washing solution, wiping
parallel to the heating elements. Also, keep all
objects a safe distance from the window to prevent
damaging the heating elements.

Adding Washer Fluid
The fluid reservoir for the windshield washers and the
rear window washer is shared. It is located in the front of
the engine compartment on the passenger side and
should be checked for fluid level at regular intervals. Fill
the reservoir with windshield washer solvent (not radia-
tor antifreeze) and operate the system for a few seconds
to flush out the residual water.

INSTRUMENT CLUSTER DESCRIPTION
Your vehicle is equipped with the instrument cluster
described on the following pages.
1. Voltmeter Indicates available battery voltage and charging
system operation. The lower red zone indicates
that battery charge may be too low to start the engine.
With the engine running, the normal operating range is
between 11 and 15 volts. Prolonged gauge readings
between 8-11 (undercharge) or above 15 (overcharge)
indicate possible malfunction of generator, voltage regu-
lator or battery. See your dealer if such indications occur.
2. Front Fog Light Indicator Light — If Equipped This light shows when the front fog lights are on.
3. Cruise Indicator Light This light shows when the electronic speed
control system is turned on. 4. Sentry Key Indicator Light — If Equipped
Refer to “Sentry Key Immobilizer System” in
Section 2 of this manual. (See page 14 for more
information.)
5. Tachometer
Indicates the engine speed in revolutions per minute
(RPM).
CAUTION!
Do not operate the engine with the tachometer
pointer in the red area. Engine damage will occur.
6. 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).

13. Oil Pressure Gauge Indicates engine oil pressure. This gauge does not
indicate oil level, and pressure varies with engine
speed, temperature and oil viscosity. Consistent lower
readings indicate possible malfunction. Seek authorized
service.
14. Coolant Temperature Gauge Indicates engine coolant temperature. The red
zone to the far right indicates possible overheat-
ing. Seek authorized service immediately if the
gauge operates in the red zone. In U.S. vehicles, tempera-
ture is indicated in degrees fahrenheit; in Canadian
vehicles in degrees centigrade.
15. Airbag Warning Light This indicator lights and remains lit for 6 to 8
seconds when the ignition is first turned on. If
the light does not come on for 6 to 8 seconds, stays on or comes on while driving, have the airbag
system checked by an authorized dealer.
16. Check Gauges Warning Light
This light monitors the engine coolant tem-
perature, engine oil pressure, and voltage
gauges. If it detects an extreme condition a
chime will sound and the light will come on. If the light
comes on, check the operation of these gauges for a
malfunction condition.
17. 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. (See page 268 for more
information.)
18. Trip Odometer Button
Press and release this button to toggle between the
odometer and trip odometer displays. This button is also
used to reset the trip odometer to 0. While the display is
showing the trip odometer, press and hold the button for
approximately 2 seconds and the display will reset to 0. 19. Odometer/Trip Odometer
The odometer shows the total distance the vehicle has
been driven.
The odometer will “illuminate” when the driver’s door
has been opened, and will remain on for 20 seconds after
exiting the vehicle.
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.
The trip odometer shows individual mileage up to 999.9
miles (1 600 km). To switch from odometer to trip
odometer, press the trip odometer button.

23. Fuel Cap Indicator This symbol indicates the side of the vehicle
where the fuel cap is located.
24. Fuel Gauge
The pointer shows the level of fuel in the fuel tank. When
the fuel gauge pointer initially moves to E, for your
safety, approximately 2 U.S. Gallons (7.6L) of fuel remain.
NOTE: When the ignition switch is turned to OFF, the
fuel gauge, voltmeter, oil pressure and temperature
gauges may not show accurate readings. When the
engine is not running, turn the ignition switch to ON to
obtain accurate readings.ELECTRONIC DIGITAL CLOCK
The clock and radio each use the display panel built into
the radio. A digital readout shows the time in hours and
minutes whenever the ignition switch is in the ON or
ACC position and the time button is pressed.
When the ignition switch is in the OFF position, or when
the radio frequency is being displayed, time keeping is
accurately maintained.
Clock Setting Procedure
1. Turn the ignition switch to the ON or ACC position
and press the time button. Using the tip of a ballpoint pen
or similar object, press either the hour (H) or minute (M)
buttons on the radio.
2. Press the H button to set hours or the M button to set
minutes. The time setting will increase each time you
press a button.

Mix Outside air comes from the floor and defrost out-
lets. This mode works best in cold or snowy con-
ditions. It allows you to stay comfortable while
keeping the windshield clear.
Defrost Outside air comes from the windshield outlets
with a small amount being directed through the
floor outlets. Use this setting when necessary to defrost
your windshield.
NOTE: For improved safety, the A/C compressor is
activated when “Mix” or “Defrost” modes are selected.
This is done to assist in drying the air and it will help in
keeping the windshield from fogging.Operating Tips
Summer Operation
The engine cooling system in air conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A 50% solution of ethylene
glycol antifreeze coolant in water is recommended.
Winter Operation
The air from the heater system will heat faster in cold
weather if you use lower blower speeds until the engine
warms up. 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.
