2010 JEEP LIBERTY ignition

•Air Conditioner ControlPress this button to turn on the air
conditioning during manual operation
only. When the air conditioning is
turned on, cool dehumidified air will
flow through the outlets selected with
the Mode control dial. Press this but-
ton a second time to turn OFF the air
conditioning. An LED in the button illuminates when
manual compressor operation is selected.
•Recirculation Control The system will automatically control recircu-
lation. However, pressing the Recirculation
Control button will temporarily put the system
in recirculation mode (ten minutes). This can
be used when outside conditions such as smoke, odors, dust, or high humidity are present. Activating recircula-
tion will cause the LED in the control button to illumi-
nate. After ten minutes, the system will return to normal
AUTO mode function and the LED will turn off.
NOTE:
•When the ignition switch is turned to the LOCK
position, the recirculation feature will be cancelled.
•In cold weather, use of the Recirculation mode may
lead to excessive window fogging. The Recirculation
mode is not allowed in the floor, defrost, or defrost/
floor mode in order to improve window clearing.
Recirculation will be disabled automatically if these
modes are selected.

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.
Start the engine with the shift lever in the NEUTRAL or
PARK position. Apply the brake before shifting to any
driving range.
Normal Starting
NOTE: Normal starting of either a cold or a warm
engine is obtained without pumping or pressing the
accelerator pedal. Turn the ignition switch to the START position and
release 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.
Tip Start Feature
Turn the ignition switch to START position and release it
as soon as the starter engages. The starter motor will
continue to run, but will automatically disengage itself
when the engine is running. If the engine fails to start, the
starter will disengage automatically in 10 seconds. If this
occurs, turn the ignition switch to the LOCK position,
wait 10 to 15 seconds, then repeat the “Normal Starting”
procedure.

STARTING AND OPERATING 299

Then, turn the ignition switch to the START position and
release it as soon as the starter engages. The starter motor
will disengage automatically in 10 seconds. Once this
occurs, release the accelerator pedal, turn the ignition
switch to the LOCK position, wait 10 to 15 seconds, then
repeat the “Normal Starting” procedure.
CAUTION!
To prevent damage to the starter, wait 10 to 15 sec-
onds before trying again.
After Starting
The idle speed will automatically decrease as the engine
warms up.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up may
cause serious injury or death.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a
standard 110-115 Volt AC electrical outlet with a
grounded three-wire extension cord.
•The engine block heater cord is found under the hood
clipped to the heater line on the left side of the engine.

STARTING AND OPERATING 301

WARNING!
It is dangerous to move the shift lever out of PARK or
NEUTRAL if the engine speed is higher than idle
speed. If your foot is not firmly on the brake pedal,
the vehicle could accelerate quickly forward or in
reverse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when the
engine is idling normally and when your foot is
firmly on the brake pedal.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the shift lever to be placed in PARK
prior to rotating the key to the LOCK position. The key
can only be removed from the ignition when the ignition
is in the LOCK position and once removed the shift lever
is locked in PARK.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the shift lever in the
PARK position when the ignition switch is in the LOCK
position. To move the shift lever out of the PARK
position, the ignition switch must be turned to any other
switch position (ACC, ON, or START) (engine running or
not) and the brake pedal must be pressed.
Brake/Transmission Interlock Manual Override
Your vehicle may be equipped with a shift lock manual
override. The manual override may be used in the event
that the shift lever should fail to move from PARK with
the key in the ON position and the brake pedal pressed.
To operate the shift lock manual override, perform the
following steps:
1. Turn the key to the ON position but do not start the
engine.
2. Firmly set the parking brake.5

the vehicle stopped or in motion. With the vehicle in
motion, the transfer case will engage/disengage faster if
you momentarily release the accelerator pedal after mov-
ing the transfer case switch. If the vehicle is stopped, the
ignition switch must be in the ON position with the
engine either OFF or RUNNING. This shift cannot be
completed if the ignition switch is in the ACC position.
NOTE:The four-wheel drive system will not allow
shifts between 2WD and 4WD LOCK if the rear wheels
are spinning (no traction). In this situation, the selected
position indicator light will flash and the original posi-
tion indicator light will remain ON. At this time, reduce
speed and stop spinning the wheels to complete the shift.
There may be a delay up to 10 seconds for the shift to
complete after the wheels have stopped spinning.
Delayed shifting out of 4WD LOCK may be experienced
due to uneven tire wear, low tire pressure, or excessive
loading. 4WD Lock to 4WD Low
When shifting into or out of 4WD LOW, some gear noise
may be heard. This noise is normal and is not detrimental
to the vehicle or its occupants.
Shifting can be performed with the vehicle rolling 2 to
3 mph (3 to 5 km/h) using the “Preferred Procedure” or
completely stopped using the “Alternate Procedure.”
Preferred Procedure
1. With the engine RUNNING, slow the vehicle speed to
2 to 3 mph (3 to 5 km/h).
2. Shift the transmission into NEUTRAL.
3. While still rolling, move the transfer case switch to the
desired position.
4. After the desired position indicator light is ON (not
flashing), shift the transmission into gear.
314 STARTING AND OPERATING

Alternate Procedure
1. Bring the vehicle to a complete stop.
2. With the ignition switch in the ON position, and the
engine OFF or RUNNING, shift the transmission into
NEUTRAL.
3. Move the transfer case switch to the desired position.
4. After the desired position indicator light is on (not
flashing), shift the transmission into gear.
NOTE:Steps 1 and 2 in the “Preferred Procedure” and
the “Alternate Procedure” are requirements for shifting
the transfer case. If these requirements are not met prior
to attempting the shift or while the shift attempt is in
process, then the indicator light will flash, and the
current transfer case position will be maintained. To retry
a shift, move the transfer case switch back to the original
position, make certain all shift requirements have been
met, wait five seconds, and try the shift again. The ignition switch must be in the ON position for a shift
to take place and for the position indicator lights to be
operable. If the ignition switch is not in the ON position,
then the shift will not take place and no position indicator
lights will be on or flashing.
