ECO mode JEEP LIBERTY 2012 KK / 2.G Repair Manual

NOTE:TOW/HAUL mode locks out Overdrive.
The “TOW/HAUL Indicator Light” will illuminate in the
instrument cluster to indicate that TOW/HAUL mode
has been activated. Pressing the switch a second time
restores normal operation. If the TOW/HAUL mode is
desired, the switch must be pressed each time the engine
is started.Torque Converter Clutch
A feature designed to improve fuel economy has been
included in the automatic transmission on your vehicle.
A clutch within the torque converter engages automati-
cally at calibrated speeds. This may result in a slightly
different feeling or response during normal operation in
the upper gears. When the vehicle speed drops or during
some accelerations, the clutch automatically disengages.
NOTE: The torque converter clutch will not engage
until the transmission fluid and engine coolant are warm
[usually after 1 to 3 miles (1.6 to 4.8 km) of driving].
Because the engine speed is higher when the torque
converter clutch is not engaged, it may seem as if the
transmission is not shifting into Overdrive when cold.
This is normal. Pressing the TOW/HAUL switch, when
the transmission is sufficiently warm, will demonstrate
that the transmission is able to shift into and out of
Overdrive.

Partial Off – Two-Wheel Drive Vehicles And
Four-Wheel Drive Vehicles In 2WD And 4WD High
Range
The “Partial Off” mode is intended for driving in deep
snow, sand, or gravel. This mode raises the threshold for
TCS and ESC activation, which allows for more wheel
spin than what ESC normally allows.
The “ESC Off” button is located in the lower switch bank
below the climate control. To enter the “Partial Off”
mode, momentarily press the “ESC Off” button and the
ESC Activation/Malfunction Indicator Light” will illu-
minate. To turn the ESC on again, momentarily press the
ESC Offbutton and the ESC Activation/Malfunction
Indicator Light” will turn off. This will restore the normal
“ESC On” mode of operation.
NOTE: To improve the vehicle’s traction when driving
with snow chains, or when starting off in deep snow,
sand, or gravel, it may be desirable to switch to the “Partial Off” mode by momentarily pressing the “ESC
Off” button. Once the situation requiring “Partial Off”
mode is overcome, turn ESC back on by momentarily
pressing the “ESC Off” button. This may be done while
the vehicle is in motion.
Full Off – Four-Wheel Drive Vehicles In 4WD High
And 4WD Low Range
The “Full Off” mode is intended for off-highway and
off-road use when ESC stability features could inhibit
vehicle maneuverability due to trail conditions.
The “ESC Off” button is located in the lower switch bank
below the climate control panel. To enter “Full Off”
mode, press and hold the “ESC Off” button for five
seconds while the vehicle is stopped with the engine
running. After five seconds, the “ESC Activation/
Malfunction Indicator Light” will illuminate and an “ESC
OFF” message will appear in the odometer. Press and
release the trip odometer button located on the instru-
ment cluster to turn off this message.

E-85 Usage In Non-Flex Fuel Vehicles
Non-FFV vehicles are compatible with gasoline contain-
ing 10% ethanol (E10). Gasoline with higher ethanol
content may void the vehicle’s warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symptoms:
•operate in a lean mode
•OBD II “Malfunction Indicator Light” on
•poor engine performance
•poor cold start and cold drivability
•increased risk for fuel system component corrosionTo fix a Non-FFV vehicle inadvertently fueled once with
E-85 perform the following:
•drain the fuel tank (see your authorized dealer)
•change the engine oil and oil filter
•disconnect and reconnect the battery to reset the
engine controller memory
More extensive repairs will be required for prolonged
exposure to E-85 fuel.
MMT In Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug
life and reduces emission system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content

STARTING AND OPERATING 401

If the vehicle’s battery is discharged, refer to “Shift Lever
Override” in “What To Do In Emergencies” for instruc-
tions on shifting the automatic transmission out of the
PARK position for towing.
CAUTION!
•Do not attempt to use sling type equipment when
towing. When securing the vehicle to a flat bed
truck, do not attach to front or rear suspension
components. Damage to your vehicle may result
from improper towing.
•If the vehicle being towed requires steering, the
ignition must be in the ON/RUN or ACC position,
not in the LOCK/OFF position.
Towing Without The Ignition Key Fob
Special care must be taken when the vehicle is towed
with the ignition in the LOCK/OFF position. The only
approved method of towing without the ignition key is
with a flatbed truck. Proper towing equipment is neces-
sary to prevent damage to the vehicle.
Two-Wheel Drive Models
The manufacturer recommends towing your vehicle with
all four wheelsOFFthe ground using a flatbed.
If flatbed equipment is not available, and the transmis-
sion is operable, the vehicle may be towed (with rear
wheels on the ground) with the transmission in NEU-
TRAL. Speed must not exceed 30 mph (48 km/h) and the
distance must not exceed 15 miles (24 km).
452 WHAT TO DO IN EMERGENCIES

Four-Wheel Drive Models
The manufacturer recommends towing with all wheels
OFFthe ground. Acceptable methods are to tow the
vehicle on a flatbed or with one end of vehicle raised and
the opposite end on a towing dolly.
If flatbed equipment is not available, and the transfer
case is operable, the vehicle may be towed (in the
forward direction, with ALLwheels on the ground), IF
the transfer case is in NEUTRAL and the transmission is
in PARK. Refer to “Recreational Towing” in “Starting
And Operating” for detailed instructions.CAUTION!
•Front or rear wheel lifts should not be used.
Internal damage to the transmission or transfer
case will occur if a front or rear wheel lift is used
when towing.
•Failure to follow these towing methods can cause
severe damage to the transmission and/or transfer
case. Such damage is not covered by the New
Vehicle Limited Warranty.
