light JEEP LIBERTY 2006 Workshop Manual

Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“GAS CAP” message will be displayed in the odometer
(located on the instrument cluster). Replace, or tighten
the fuel filler cap properly to turn the message off (light
will time out). If the problem continues, the message will
appear the next time the vehicle is started. Refer to
“Onboard Diagnostic System — OBDII” in Section 7 of
this manual for more information. (See page 316 for more
information.)
CAUTION!
Damage to the fuel system or emission control
system could result from using an improper fuel
tank filler cap (gas cap). A poorly fitting cap could let
impurities into the fuel system.
WARNING!

Brake and Power Steering System Hoses
When servicing the vehicle for scheduled maintenance,
inspect surface of hoses for evidence of heat and me-
chanical damage. Hard and brittle rubber, cracking, tears,
cuts, abrasion, and excessive swelling suggest deteriora-
tion of the rubber. Particular attention should be made to
examining those hose surfaces nearest to high heat
sources, such as the exhaust manifold.
Inspect all hose clamps and couplings to make sure they
are secure and no leaks are present.
NOTE: Often fluids such as oil, power steering fluid,
and brake fluid are used during assembly plant opera-
tions to ease the assembly of hoses to couplings. There-
fore, oil wetness at the hose-coupling area is not neces-
sarily an indication of leakage. Actual dripping of hot
fluid when systems are under pressure (during vehicle
operation) should be noted before hose is replaced based
on leakage. NOTE:
Inspection of brake hoses should be done when-
ever the brake system is serviced and every engine oil
change.
WARNING!
Worn brake hoses can burst and cause brake failure.
You could have an accident. If you see any signs of
cracking, scuffing, or worn spots, have the brake
hoses replaced immediately.
Brake Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately if
the “Brake Warning Light” shows system failure.

Electrical Outlet Use With Engine Off
•Many accessories that can be plugged in draw
power from the vehicle’s battery, even when not
in use (i.e., cellular phones, etc.). Eventually, if
plugged in long enough, the vehicle’s battery will
discharge sufficiently to degrade battery life
and/or prevent engine starting.
•Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.) will degrade the
battery even more quickly. Only use these inter-
mittently and with greater caution.
•After the use of high power draw accessories, or
long periods of the vehicle not being started (with
accessories still plugged in), the vehicle must be
driven a sufficient length of time to allow the
alternator to recharge the vehicle’s battery.

17. Part Time Indicator Light — If Equipped This light alerts the driver that the vehicle is in
the PART TIME four–wheel drive high range
mode, and the front and rear driveshafts are
mechanically locked together forcing the front and rear
wheels to rotate at the same speed. (See page 234 for
more information.)
18. Brake Warning Light This light monitors various brake functions,
including brake fluid level and parking brake
application. If the light comes on, it may indi-
cate that the parking brake is applied, or there
is a low brake fluid level. On vehicles equipped with
Anti-Lock brakes (ABS), it may also indicate an ABS
malfunction that could lead to reduced braking perfor-
mance.WARNING!
Driving a vehicle with the BRAKE warning light on
is dangerous. A significant decrease in braking per-
formance or vehicle stability during braking may
occur. It will take you longer to stop the vehicle or
will make your vehicle harder to control. You could
have an accident. Have the vehicle checked immedi-
ately.

Over Temperature Mode
The transmission electronics constantly monitor the
transmission oil temperature. If the transmission gets too
hot, the transmission will change the way it shifts to help
control the condition. This may result in a slightly different feeling or response during normal operation in
D (Drive) position. If the transmission becomes hot
enough the TRANS TEMP warning light in the instru-
ment cluster will come on. After the transmission cools
down, it will return to normal operation.
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.
NOTE:
•The torque converter clutch (TCC) will not engage
until the transmission fluid and engine coolant are
warm (usually after 1–3 miles (1.6–4.8 km) of driving)
and the vehicle speed is above approximately 30 mph
232 STARTING AND OPERATING

To release the parking brake, pull up slightly, press the
center button, then lower the lever completely.
Before leaving the vehicle parked on a hill, you must
make sure the parking brake is fully applied and place
the gear selector in the P (Park) position. Make certain the
transfer case is in gear. Failure to do so may cause the
vehicle to roll and cause damage or injury.
When parking on a hill, it is important to set the parking
brake before placing the gear selector in P (Park), other-
wise the load on the transmission locking mechanism
may make it difficult to move the selector out of P (Park).WARNING!

During off-road use, loss of traction can temporarily
defeat the system and cause the warning light to illumi-
nate. Turn the ignition OFF and ON again to restore
Anti-Lock Brake System function.
WARNING!
Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to an accident.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need to
slow down or stop.
WARNING!
