2010 JEEP LIBERTY 4WD

15. Tachometer
This gauge measures engine revolutions-per-minute
(RPM x 1000). Before the pointer reaches the red area,
ease up on the accelerator to prevent engine damage.
16. 4WD LOW Indicator — If EquippedThis light alerts the driver that the vehicle is in
the 4WD LOW mode. In this mode, the front
driveshaft and rear driveshaft are mechanically
locked together forcing the front and rear
wheels to rotate at the same speed.
17. Hill Descent Control Indicator — If Equipped The symbol indicates the status of the Hill
Descent Control (HDC) feature. The lamp will
be on solid when HDC is armed. HDC can only
be armed when the transfer case is in the “4WD
LOW” position and the vehicle speed is less then 30 mph (48 km/h). If these conditions are not met while attempt-
ing to use the HDC feature, the HDC indicator light will
flash on/off.
18. TOW/HAUL Indicator — If Equipped
This light will illuminate when selecting
TOW/HAUL. The TOW/HAUL button is lo-
cated on the gearshift bezel.
19. 4WD Indicator — Vehicles Equipped with
Command-Trac This light alerts the driver that the vehicle is in
the four-wheel drive mode. In this mode, the
front driveshaft and rear driveshaft are me-
chanically locked together forcing the front and
rear wheels to rotate at the same speed.

20. Electronic Stability Control (ESC) OFF Indicator
Light — If EquippedThis light indicates the Electronic Stability Con-
trol (ESC) is off.
21. SERV (Service) 4WD Indicator Light — If Equipped The “SERV 4WD Indicator Light” will turn on
when the ignition key is turned to the ON
position and it will stay on for two seconds. If
the light stays on or turns on during driving, it
means that the 4WD system is not functioning properly
and that service is required.
22. Engine Temperature Warning Light This light warns of an overheated engine condi-
tion. As temperatures rise and the gauge ap-
proaches H,this indicator will illuminate and a
single chime will sound after reaching a set threshold.
Further overheating will cause the temperature gauge to pass
H,the indicator will continuously flash and a
continuous chime will occur until the engine is allowed
to cool.
If the light turns on while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also,
shift the transmission into NEUTRAL and idle the ve-
hicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service. Refer to “If Your Engine Overheats” in Section 6
for more information.
23. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.

CAUTION!
Continuous driving with the Transmission Tempera-
ture Indicator illuminated will eventually cause se-
vere transmission damage or transmission failure.
WARNING!
In some circumstances a Transmission Temperature
Indicator, under continued operation, could cause the
fluid to boil over, come in contact with hot engine or
exhaust components and cause a fire.
25. Odometer / Trip Odometer / ECO (Fuel Saver
Indicator) Button
Changing the Display
Press this button to change the display from odometer to
either of the two trip odometer settings or the “ECO”
display. Trip A or Trip B will appear when in the trip odometer mode. On vehicles equipped with a Base
Cluster, press and release it once again to display the
outside temperature. On vehicles equipped with a Mid
Line Cluster, press and release it once again to display the
outside temperature and compass heading in the screen
below the speedometer. Refer to “Electronic Vehicle In-
formation Center (EVIC) — If Equipped” for details.
Resetting the Trip Odometer
Display the trip mileage that you want to reset, “Trip A”
or “Trip B.” Then push and hold the button (approxi-
mately two seconds) until the display resets to 0. The
odometer must be in Trip Mode to reset the trip odom-
eter.

This light alerts the driver that the vehicle is in
the full-time four-wheel drive auto mode. In
this mode, the system operates with a normal

296 STARTING AND OPERATING

If the problem is no longer detected, the transmission will
return to normal operation. If the problem persists,
PARK, REVERSE, and NEUTRAL will continue to oper-
ate. Only second gear range will operate in the DRIVE
position. Have the transmission checked at your autho-
rized dealer as soon as possible.
Torque Converter Clutch
A feature designed to improve fuel economy has been
added to the automatic transmission of this vehicle. A
clutch within the torque converter engages automatically
at calibrated speeds. This may result in a slightly differ-
ent feeling or response during normal operation in high
gear. When the vehicle speed drops or during accelera-
tion, the clutch automatically and smoothly disengages.
FOUR-WHEEL DRIVE OPERATION
MP1522 Command-TracTransfer Case — If
Equipped
Operating Information and Precautions
The Command-Trac transfer case provides four positions:
•Two–wheel drive (2WD) high range
•Four-wheel drive (4WD LOCK) high range
•Four-wheel drive (4WD LOW) low range
•Neutral (N)
This transfer case is intended to be driven in the two-
wheel drive position (2WD) for normal street and high-
way conditions such as dry hard-surfaced roads.
When additional traction is required, select the transfer
case 4WD LOCK position or 4WD LOW position. This
5
STARTING AND OPERATING 309

position locks the front driveshaft and rear driveshaft
together and forces the front and rear wheels to rotate at
the same speed.
Use the transfer case NEUTRAL position for recreational
towing only. Refer to “Recreational Towing” in this
section for specific procedures on shifting into and out of
NEUTRAL.
CAUTION!
•Do not attempt to make a shift while only the front
wheels or rear wheels are spinning. The MP1522
Command-Tractransfer case is not equipped
with a synchronizer and therefore the speed of the
front driveshaft and rear driveshaft must be equal
for the shift to take place. Shifting while only the
front wheels or rear wheels are spinning can cause
damage to the transfer case.
(Continued)
CAUTION! (Continued)
•The 4WD LOCK position and 4WD LOW position
are intended for loose or slippery road surfaces
only. Driving in these positions on dry hard-
surfaced roads may cause increased tire wear and
damage to the driveline components.
•When operating your vehicle in 4WD LOW, the
engine speed is approximately three times that of
the 2WD position or 4WD LOCK position at a
given road speed. Take care not to over-speed the
engine and do not exceed 25 mph (40 km/h).
•Proper operation of four-wheel drive vehicles de-
pends on tires of equal size, type, and circumfer-
ence on each wheel. Any difference in tire size can
cause damage to the transfer case.
310 STARTING AND OPERATING

WARNING!
•You or others could be injured if you leave the
vehicle unattended with the transfer case in the
NEUTRAL position without first fully engaging
the parking brake. The transfer case NEUTRAL
position disengages both the front driveshaft and
rear driveshaft from the powertrain and it will
allow the vehicle to move even if the transmission
is in PARK. The parking brake should always be
applied when the driver is not in the vehicle.
•Always engage the parking brake when powering
down the vehicle if the “SERV 4WD Warning
Light” is illuminated. Not engaging the parking
brake may allow the vehicle to roll, which may
cause personal injury.(Continued)
WARNING! (Continued)
•Since four-wheel drive provides improved trac-
tion, there is a tendency to exceed safe turning and
stopping speeds. Do not go faster than road con-
ditions permit. You or others could be injured.
