2008 JEEP LIBERTY clutch

WARNING!
Leaving the Electronic Speed Control system 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
leave the system OFF when you are not using it.
To Set At A Desired Speed:
When the vehicle reaches the speed desired, press down
on the lever and release (ªSET DECELº). Release the
accelerator and the vehicle will operate at the selected
speed.
NOTE:
²The vehicle must be traveling at least 25 mph (40
km/h) for the speed control to set.
²The vehicle should be traveling at a steady speed and
on level ground before pressing the lever (ªSET DE-
CELº).
To Deactivate:
A soft tap on the brake pedal, or pulling the speed control
lever toward you (ªCANCELº), or normal brake or
clutch pressure while slowing the vehicle will deactivate
the speed control without erasing the set speed from
memory. Pressing the (ON/OFF) button or turning off
the ignition erases the set speed from memory.
NOTE:For vehicles equipped with a manual transmis-
sion, depressing the clutch pedal will disengage the
speed control. A slight increase in engine RPM before the
speed control disengages is normal.

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust both
inside and outside mirrors, and fasten your seat belts.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
Automatic Transmission
Start the engine with the selector lever in the ªNº
(Neutral) or ªPº (Park) position. Apply the brake before
shifting to any driving range.
Manual Transmission Ð If Equipped
Apply the parking brake, place the gearshift control lever
in ªNº (Neutral) and depress the clutch pedal beforestarting vehicle. This vehicle is equipped with a clutch
interlocking ignition system. It will not start unless the
clutch pedal is pressed to the floor.
4WD Models Only
To enhance off-road performance, 4-wheel drive models
equipped with a manual transmission will start with or
without pressing the clutch pedal when in 4-wheel drive
low range. The 4 LOW indicator light will illuminate
when the transfer case is in 4-wheel drive low range.
Normal Starting
NOTE:Normal starting of either a cold or a warm
engine is obtained without pumping or depressing the
accelerator pedal.
For vehicles not equipped with Tip Start,turn the ignition
switch to the START position and release it when the
engine starts. If the engine fails to start within 10 seconds,
turn the ignition switch to the LOCK position, wait 10 to
15 seconds, then repeat the normal starting procedure.

The ªTOW/HAUL Indicator Lightº will illuminate in the
instrument cluster to indicate when the switch has been
activated. Pressing the switch a second time restores
normal operation. If the ªTOW/HAULº 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
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.
Transmission Limp Home Mode
The transmission is monitored for abnormal conditions.
If a condition is detected that could cause damage, the
transmission shifts automatically into second gear if the
vehicle speed is appropriate. If not, it will wait until the
conditions are appropriate and then it will shift into
second gear. The transmission will then remain in second
gear despite the forward gear selected. ªPº (Park), ªRº
(Reverse), and ªNº (Neutral) will continue to operate.

A Reset feature allows the vehicle to be driven to a dealer
for service without damaging the transmission. To reset
the transmission, perform the following procedure:
1. Stop the vehicle.
2. Move the selector lever to the ªPº (Park) position.
3. Turn off the engine; be sure to turn the key to the
LOCK position.
4. Wait approximately 10 seconds, and then restart the
engine.
5. Move the selector lever to the desired gear range.
If the problem is no longer detected, the transmission will
return to normal operation. If the problem persists, ªPº
(Park), ªRº (Reverse), and ªNº (Neutral) will continue to
operate. Only Second gear range will operate in the ªDº
(Drive) position. Have the transmission checked at your
authorized dealer as soon as possible.MANUAL TRANSMISSION Ð IF EQUIPPED
Clutch Interlocking Ignition System
Vehicles equipped with a manual transmission are
equipped with a clutch interlock safety feature. The
clutch pedal must be fully depressed to allow cranking of
the engine.
To enhance off-road performance, 4-wheel drive models
equipped with a manual transmission will start with or
without pressing the clutch pedal when in 4-wheel drive
low range. The 4 LOW indicator light will illuminate
when the transfer case is in 4-wheel drive low range.
288 STARTING AND OPERATING

WARNING!
When parking your vehicle, always leave a manual
transmission in first gear and apply the parking
brake fully to guard against vehicle movement and
possible injury or damage. Never use any gear as a
substitute for the parking brake.
CAUTION!
To drive as safely as possible and to prolong the life
of your manual transmission, follow these tips:
²Before shifting from a forward gear into reverse, or
from reverse to a forward gear, stop vehicle com-
pletely. Otherwise, accelerated transmission wear may
result.
²Do not operate at sustained high engine or road
speeds in lower gears. Engine damage may result.
²Do not downshift into a low gear while traveling at too
high a speed for that gear. Engine, clutch, or transmis-
sion damage may result.
²Do not rest your foot on the clutch pedal. This causes
heat buildup and damages the clutch.
²When you slow down or go up a grade, downshift as
speed requires or the engine may overheat.
²Never hold the vehicle stopped on a hill by using the
clutch pedal. The clutch may be damaged.
²During cold weather, you may experience increased
effort in shifting until the transmission fluid warms
up. This is normal.
²Push in the clutch pedal completely when shifting.
Otherwise, transmission or clutch damage may result.
290 STARTING AND OPERATING

²When ªrockingº a stuck vehicle by shifting between a
forward gear and reverse, do not spin wheels faster
than 15 mph (24 km/h), or drivetrain damage may
result.

Failure to follow the recommended downshifting
speeds may cause the engine to over speed and/or
damage the clutch disc even if the clutch pedal is
depressed.
FOUR-WHEEL DRIVE OPERATION
MP1522 Command-TracTTransfer Case Ð If
Equipped
Operating Information & Precautions
The Command-Tracttransfer case provides four posi-
tions:
²2 (rear) wheel drive high range.
²4-wheel drive high range.
²Neutral.
²4-wheel drive low range.
This transfer case is intended to be driven in the 2-wheel
drive position (2WD) for normal street and highway
conditions such as dry hard surfaced roads.
When additional traction is required, select the transfer
case 4WD Lock position or 4WD Low position. This
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 (N) position for recreational
towing only. Refer to ªRecreational Towingº in this
section for specific procedures on shifting into and out of
Neutral (N).
