2012 JEEP LIBERTY ignition

In this mode, ESC and TCS are turned off (except for the
“limited slip” feature described in the TCS section) until
the vehicle reaches a speed of 40 mph (64 km/k). At
speeds over 40 mph (64 km/k), the system automatically
switches to “Partial Off” mode, described above. When
the vehicle speed returns to less than 35 mph (56 km/h),
the ESC system will return to “Full Off” mode. The “ESC
Activation/Malfunction Indicator Light” is always illu-
minated when ESC is off. To turn ESC on again, momen-
tarily press the “ESC Off” button. This will restore the
normal “ESC On” mode of operation.
NOTE:
•“Full Off” is the only operating mode for ESC in 4WD
LOW range. The ESC system will be in this mode
whenever the vehicle is started in 4WD LOW range or
the transfer case is shifted into 4WD LOW range.
•The “ESC OFF” message will display and a chime will
sound when the shift lever is moved from any positionto the PARK position and then moved out of the PARK
position. This will occur even if the message was
cleared previously.
WARNING!
With the ESC switched off, the enhanced vehicle
stability offered by ESC is unavailable. In an emer-
gency evasive maneuver, the ESC system will not
engage to assist in maintaining stability. “Full Off”
mode is only intended for off-highway or off-road
use.
ESC Activation/Malfunction Indicator Light And
ESC OFF Indicator Light
The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is turned to the ON
position. It should go out with the engine
running. If the “ESC Activation/Malfunction Indicator
366 STARTING AND OPERATING

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), see your autho-
rized dealer as soon as possible to have the problem
diagnosed and corrected.
The “ESC Activation/Malfunction Indicator Light” (lo-
cated in the instrument cluster) starts to flash as soon as
the tires lose traction and the ESC system becomes active.
The “ESC Activation/Malfunction Indicator Light” also
flashes when TCS is active. If the “ESC Activation/
Malfunction Indicator Light” begins to flash during ac-
celeration, 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.NOTE:
•The “ESC Activation/Malfunction Indicator Light”
and the “ESC OFF Indicator Light” come on momen-
tarily each time the ignition switch is turned ON.
•Each time the ignition is turned ON, the ESC system
will be ON even if it was turned off previously.
•The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.
The “ESC OFF Indicator Light” indicates the
Electronic Stability Control (ESC) is off.

Service TPMS Warning
When a system fault is detected, the “Tire Pressure
Monitoring Telltale Light” will flash on and off for
75 seconds and then remain on solid. The system fault
will also sound a chime. If the ignition key is cycled, this
sequence will repeat, providing the system fault still
exists. The “Tire Pressure Monitoring Telltale Light” will
turn off when the fault condition no longer exists. A
system fault can occur due to any of the following:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the TPMS
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel
housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.Vehicles With Full-Size Spare
1. The matching full-size spare wheel and tire assembly
has a tire pressure monitoring sensor that can be moni-
tored by the TPMS.
2. If you install the full-size spare in place of a road tire
that has a pressure below the low-pressure warning limit,
a chime will sound and the “TPMS Telltale Light” and
“LOW TIRE PRESSURE” message will turn on upon the
next ignition key cycle.
3. Driving the vehicle for up to 20 minutes above 15 mph
(24 km/h) will turn off the “TPMS Telltale Light,” as long
as no tire pressure is below the low-pressure warning
limit in any of the four active road tires.
Vehicles With Compact Spare
1. The compact spare tire does not have a tire pressure
monitoring sensor. Therefore, the TPMS will not monitor
the pressure in the compact spare tire.

2. If you install the compact spare tire in place of a road
tire that has a pressure below the low-pressure warning
limit, a chime will sound and the “TPMS Telltale Light”
and “LOW TIRE PRESSURE” message will turn on upon
the next ignition key cycle.
3. After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the “TPMS Telltale Light” will flash
on and off for 75 seconds and then remain on solid.
4. For each subsequent ignition key cycle, a chime will
sound and the “TPMS Telltale Light” will flash on and off
for 75 seconds and then remain on solid.
5. Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically and the “TPMS
Telltale Light” will turn off, as long as no tire pressure is
below the low-pressure warning limit in any of the fouractive road tires. The vehicle may need to be driven for
up to 20 minutes above 15 mph (24 km/h) in order for the
TPMS to receive this information.
Premium System – If Equipped
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the receiver module.
NOTE:
It is particularly important for you to check the
tire pressure in all of the tires on your vehicle monthly
and to maintain the proper pressure.
The TPMS consists of the following components:
•Receiver Module
•Four Tire Pressure Monitoring Sensors

If the ignition key is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the “Tire Pressure Monitoring Telltale
Light” will no longer flash, and the “SERVICE TPM
SYSTEM message will no longer display, and a pressure
value will display in place of the dashes. A system fault
can occur due to any of the following:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the TPMS
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel
housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.Vehicles With Full-Size Spare

Vehicles With Compact Spare
1. The compact spare tire does not have a tire pressure
monitoring sensor. Therefore, the TPMS will not monitor
the pressure in the compact spare tire.
2. If you install the compact spare tire in place of a road
tire that has a pressure below the low-pressure warning
limit, upon the next ignition key cycle, the “TPMS Telltale
Light” will remain on and a chime will sound. In
addition, the graphic in the EVIC will still display a
flashing pressure value.
3. After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the “TPMS Telltale Light” will flash
on and off for 75 seconds and then remain on solid. In
addition, the EVIC will display a “SERVICE TPM SYS-
TEM” message for five seconds and then display dashes
(- -) in place of the pressure value.4. For each subsequent ignition key cycle, a chime will
sound, the “TPMS Telltale Light” will flash on and off for
75 seconds and then remain on solid, and the EVIC will
display a “SERVICE TPM SYSTEM” message for five
seconds and then display dashes (- -) in place of the
pressure value.
5. Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically. In addition, the
“TPMS Telltale Light” will turn off and the graphic in the
EVIC will display a new pressure value instead of dashes
(- -), as long as no tire pressure is below the low-pressure
warning limit in any of the four active road tires. The
vehicle may need to be driven for up to 20 minutes above
15 mph (24 km/h) in order for the TPMS to receive this
information.
398 STARTING AND OPERATING

of gasoline may not be indicated on the gasoline pump;
therefore, you should ask your gasoline retailer whether
the gasoline contains MMT. It is even more important to
look for gasolines without MMT in Canada, because
MMT can be used at levels higher than those allowed in
the United States. MMT is prohibited in Federal and
California reformulated gasoline.
Materials Added To Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and they would result in additional cost.
Therefore, you should not have to add anything to the
fuel.
Fuel System Cautions
CAUTION!
Use the following guidelines to maintain your vehi-
cle’s performance:
•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine perfor-
mance, and damage the emission control system.
•An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune
or malfunctioning and may require immediate
service. Contact your authorized dealer for service
assistance.(Continued)
402 STARTING AND OPERATING

Recreational Towing — Two-Wheel Drive Models
Recreational towing is allowed ONLY if the rear wheels
areOFF the ground. This may be accomplished using a
tow dolly or vehicle trailer. If using a tow dolly, follow
this procedure:
1. Properly secure the dolly to the tow vehicle, following
the dolly manufacturer’s instructions.
2. Drive the rear wheels onto the tow dolly.
3. Firmly set the parking brake. Place the transmission in
PARK.
4. Properly secure the rear wheels to the dolly, following
the dolly manufacturer’s instructions.
5. Remove the ignition key.
6. Install a suitable clamping device, designed for tow-
ing, to secure the front wheels in the straight position. Flat towing (with all four wheels on the ground) is
allowed ONLY if the driveshaft is removed.
Towing
with the rear wheels on the ground while the driveshaft
is connected will result in severe transmission damage.
WARNING!
If the driveshaft is removed, the vehicle can roll even
if the transmission is in PARK, which could cause
serious injury or death.
The parking brake mustbe firmly engaged and the
wheels chocked during driveshaft removal and installa-
tion. The parking brake must remainengaged unless the
vehicle is securely and properly connected to the tow
vehicle, or the driveshaft is completely reinstalled. See
your authorized dealer for proper driveshaft removal
and reinstallation procedures, including flange
orientation/alignment, use of thread-locking compound,
proper bolt torque specifications, etc.
