ECO mode JEEP WRANGLER 2012 JK / 3.G Owner's Manual

COMMAND-TRAC®/ROCK-TRAC®
• The transfer case provides four
mode positions: 2H (Two-wheel
drive high range), 4H (Four-wheel
drive high range), N (Neutral), and
4L (Four-wheel drive low range).
• The transfer case is intended to be
driven in the 2H position for
normal street and highway
conditions such as hard-surfaced
roads.
• Shifting between 2H and 4H can
be made with the vehicle stopped
or in motion. Shift the transfer
case lever firmly to 4H at any
speed up to 50 mph (80 km/h).
• Shifting between 4H and 4L can be made with the vehicle rolling at 2 to
3 mph (3 to 5 km/h). Shift the automatic transmission into NEUTRAL or
fully depress the clutch pedal on a manual transmission. Shift the transfer
case lever firmly to 4L (do not pause with the transfer case in
NEUTRAL). Once the shift is completed, place the automatic
transmission into DRIVE or release the clutch pedal on a manual
transmission.
NOTE:To enhance off-road performance in 4L mode, manual transmission
vehicles will start regardless of whether or not the clutch pedal is depressed.
AXLE LOCK (TRU-LOK®) RUBICON ONLY
• The AXLE LOCK switch is located on the instrument panel (to the left of
the steering column).
• This feature will only activate when the following conditions are met:
• Key in ignition, vehicle in 4L (Low) range.
• Vehicle speed at 10 mph (16 km/h) or less.
• Press the bottom of the AXLE LOCK switch once to lock the rear axle
only and a second time to lock the front axle (the rear and front axle lock
indicator lights will illuminate).
• To unlock the axles, press the top of the AXLE LOCK switch.

24-HOUR TOWING ASSISTANCE
• Dial toll-free 1-800-521-2779 or 1-800-363-4869 for Canadian residents.
• Provide your name, vehicle identification number and license plate
number.
• Provide your location, including telephone number, from which you are
calling.
• Briefly describe the nature of the problem and answer a few simple
questions.
• You will be given the name of the service provider and an estimated time
of arrival. If you feel you are in an “unsafe situation”, please let us know.
With your consent, we will contact local police or safety authorities.
INSTRUMENT CLUSTER WARNING LIGHTS
- Electronic Stability Control (ESC) Activation/Malfunction
Indicator Light
• If the “ESC Activation/Malfunction Indicator Light” comes on
continuously with the engine running, a malfunction has been detected
in the ESC system. If this light remains on after several ignition cycles,
and the vehicle has been driven several miles (kilometers) at speeds
greater than 30 mph (48 km/h), we recommend you drive to the nearest
service center and have the vehicle serviced immediately.
• The “ESC Activation/Malfunction Indicator Light” starts to flash as soon
as the tires lose traction and the ESC system becomes active. If the light
begins to flash during acceleration, ease up on the accelerator and apply
as little throttle as possible. Be sure to adapt your speed and driving to
the prevailing road conditions. The light also flashes when TCS is active.
To improve the vehicle's traction when starting off in deep snow, sand or
gravel, it may be desirable to switch the ESC system to Partial Off mode
by momentarily pressing the ESC Off
switch.
- Tire Pressure Monitoring System (TPMS) Light
• Each tire, including the spare (if provided), should be checked monthly,
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation pressure
label. (If your vehicle has tires of a different size than the size indicated
on the vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those tires.)
• As an added safety feature, your vehicle has been equipped with a Tire
Pressure Monitoring System (TPMS) that illuminates a low tire pressure
telltale when one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible, and inflate them to the
proper pressure. Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle’s handling
and stopping ability.
WHAT TO DO IN EMERGENCIES
84

Resetting The Light After Servicing
• Turn the ignition switch to the ON/RUN position (do not start engine).
• Fully depress the accelerator pedal three times within 10 seconds.
• Turn the ignition switch to the OFF/LOCK position.
HOTOIL – Transmission Temperature Warning Message
• The HOTOIL cluster message will appear in the odometer accompanied
with a chime to indicate that there is excessive transmission fluid
temperature that might occur with severe usage such as trailer towing.
• It may also occur when operating the vehicle in a high torque converter
slip condition, such as 4-wheel-drive operation (e.g., snow plowing,
off-road operation).
• If this HOTOIL message turns on, stop the vehicle and run the engine at
idle or faster, with the transmission in NEUTRAL until the message turns
off.
CAUTION!
Continuous driving with the Transmission Temperature HOTOIL
Warning message illuminated will eventually cause severe
transmission damage and transmission failure.
WARNING!
Continued operation with the Transmission Temperature HOTOIL
Warning message illuminated could cause the fluid to boil over, come
into contact with the hot engine or exhaust components causing a fire
that may result in personal injury.
IF YOUR ENGINE OVERHEATS
• In any of the following situations, you can reduce the potential for
overheating by taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission in NEUTRAL, but
do not increase engine idle speed.
NOTE:There are steps that you can take to slow down an impending
overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to
the engine cooling system and turning the A/C off can help remove this
heat.
• You can also turn the temperature control to maximum heat, the mode
control to floor and the blower control to high. This allows the heater core
to act as a supplement to the radiator and aids in removing heat from the
engine cooling system.
