JEEP LIBERTY 2008 KK / 2.G Owners Manual

Window Fogging
Interior fogging on the windshield can be quickly re-
moved by turning the mode selector to Defrost. The
Defrost/Floor mode can be used to maintain a clear
windshield and provide sufficient heating. If side win-
dow fogging becomes a problem, increase blower speed.
Vehicle windows tend to fog on the inside in mild but
rainy or humid weather.
NOTE:Recirculate without A/C should not be used for
long periods as fogging may occur.
Side Window Demisters
A side window demister outlet is located at each end of
the instrument panel. These non-adjustable outlets direct
air toward the side windows when the system is in the
FLOOR, MIX, or DEFROST mode. The air is directed at
the area of the windows through which you view the
outside mirrors.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow, and if they
enter the plenum, they could plug the water drains. In
winter months, make sure the air intake is clear of ice,
slush, and snow.
A/C Air Filter Ð If Equipped
The A/C Air Filter will reduce, but not eliminate, diesel
and agricultural smells. The filter acts on air coming from
outside the vehicle and recirculated air within the pas-
senger compartment. Refer to ªMaintenance Proceduresº
in Section 7 of this manual for A/C Air Filter service
information or see your authorized dealer for service.
Refer to the ªMaintenance Schedulesº in Section 8 of this
manual for filter service intervals.

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.
STARTING AND OPERATING 277
5

For vehicles equipped with Tip Start,turn the ignition
switch to the START position and release it as soon as the
starter engages. The starter motor will continue to run,
and it will disengage automatically 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.
Extreme Cold Weather (below ±20ÉF or ±29ÉC)
To insure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your dealer) is recommended.
If Engine Fails to Start
WARNING!
²Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury.
²Do not attempt to push or tow your vehicle to get
it started. Vehicles equipped with an automatic
transmission cannot be started this way. Unburned
fuel could enter the catalytic converter and once
the engine has started, ignite and damage the
converter and vehicle. If the vehicle has a dis-
charged battery, booster cables may be used to
obtain a start from a booster battery or the battery
in another vehicle. This type of start can be dan-
gerous if done improperly. Refer to Section 6 of
this manual for proper jump starting procedures
and follow them carefully.
278 STARTING AND OPERATING

Without Tip Start
If the engine fails to start after you have followed the
ªNormal Startingº or ªExtreme Cold Weatherº proce-
dures, it may be flooded. Push the accelerator pedal all
the way to the floor and hold it there while cranking the
engine. This should clear any excess fuel in case the
engine is flooded.
CAUTION!
To prevent damage to the starter, do not crank the
engine for more than 15 seconds at a time. Wait 10 to
15 seconds before trying again.
If the engine is flooded, it may start to run, but not have
enough power to continue running when the key is
released. If this occurs, continue cranking up to 15seconds with the accelerator pedal pushed all the way to
the floor. Release the accelerator pedal and the key once
the engine is running smoothly.
If the engine shows no sign of starting after two 15-
second periods of cranking with the accelerator pedal
held to the floor, repeat the ªNormal Startingº or ªEx-
treme Cold Weatherº procedures.
With Tip Start
If the engine fails to start after you have followed the
ªNormal Startingº or ªExtreme Cold Weatherº proce-
dures, it may be flooded. To clear any excess fuel, push
the accelerator pedal all the way to the floor and hold it.
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.
STARTING AND OPERATING 279

CAUTION!
To prevent damage to the starter, wait 10 to 15
seconds 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 Ð IF EQUIPPED
The engine block heater warms engine coolant 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.
WARNING!
Remember to disconnect the cord before driving.
Damage to the 110-115 volt AC electrical cord could
cause electrocution.
Use the heater when temperatures below 0ÉF (-18ÉC) are
expected to last for several days.
