2009 JEEP LIBERTY engine

5. Electronic Throttle Control (ETC) LightThis light informs you of a problem with the
Electronic Throttle Control (ETC) system. If a
problem is detected, the light will come on
while the engine is running. Cycle the ignition
key when the vehicle has completely stopped and the
shift lever is placed in the PARK position. The light
should turn off. If the light remains lit with the engine
running, your vehicle will usually be drivable; however,
see an authorized dealer for service as soon as possible. If
the light is flashing when the engine is running, imme-
diate service is required and you may experience reduced
performance, an elevated/rough idle or engine stall and
your vehicle may require towing. The light will come on
when the ignition is first turned ON and remain on
briefly as a bulb check. If the light does not come on
during starting, have the system checked by an autho-
rized dealer. 6. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system, called OBD, that
monitors engine and automatic transmission con-
trol systems. The light will illuminate when the key is in
the ON position, before engine start. If the bulb does not
come on when turning the key from OFF to ON, have the
condition checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc., may illuminate the MIL after
engine start. The vehicle should be serviced if the light
stays on through several of your typical driving cycles. In
most situations, the vehicle will drive normally and will
not require towing.
If the MIL flashes when the engine is running, serious
conditions may exist that could lead to immediate loss of
power or severe catalytic converter damage. The vehicle
should be serviced as soon as possible if this occurs.

7. High Beam IndicatorThis indicator shows that the high beam head-
lights are on. Pull the multifunction control lever
on the left side of the steering column toward you to
switch to low beam.
8. Front Fog Light Indicator — If Equipped This indicator will illuminate when the fog lights
are on.
9. Speedometer
Shows the vehicle speed.
10. Turn Signal Indicators The arrow will flash with the exterior turn signal
when the turn signal lever is operated.
If the vehicle electronics sense that the vehicle has
traveled about 1 mile (1.6 km) with the turn signals on, a continuous chime will sound to alert you to turn the
signals off. If either indicator flashes at a rapid rate, check
for a defective outside light bulb.
11. Electronic Stability Program (ESP) Indicator Light
/ Traction Control System (TCS) Indicator Light
If this indicator light flashes during accelera-
tion, apply as little throttle as possible. While
driving, ease up on the accelerator. Adapt your
speed and driving to the prevailing road con-
ditions, and do not switch off the Electronic Stability
Program (ESP), or Traction Control System (TCS).
12. Charging System Light This light shows the status of the electrical charg-
ing system. The light should come on when the
ignition switch is first turned ON and remain on briefly
as a bulb check. If the light stays on or comes on while
driving, turn off some of the vehicle’s non-essential
electrical devices or increase engine speed (if at idle). If

the charging system light remains on, it means that the
vehicle is experiencing a problem with the charging
system. Obtain SERVICE IMMEDIATELY. See an autho-
rized dealer.
13. Oil Pressure Warning LightThis light indicates low engine oil pressure. The
light should turn on momentarily when the engine
is started. If the light turns on while driving, stop the
vehicle and shut off the engine as soon as possible. A
chime will sound for four minutes when this light turns
on.
Do not operate the vehicle until the cause is corrected.
This light does not indicate how much oil is in the engine.
The engine oil level must be checked under the hood. 14. Anti-Lock Brake (ABS) Light
This light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON position and may
stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not turn on when the
Ignition switch is turned to the ON position, have the
light inspected by an authorized dealer.

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 Program (ESP) / Brake Assist
System (BAS) Indicator Light – If EquippedThe malfunction indicator for the Electronic
Stability Program (ESP) is combined with the
Brake Assist System (BAS). The yellow “ESP/
BAS Warning Light” in the instrument cluster
comes on when the ignition switch is turned to the ON
position. It should go out with the engine running. If the
“ESP/BAS Warning Light” comes on continuously with
the engine running, a malfunction has been detected in
either the ESP or the BAS system, or both. If this light
remains on after the several ignition cycles, and the
vehicle has been driven several miles/kilometers at
speeds greater than 30 mph (48 km/h), see an authorized
dealer as soon as possible to have the problem diagnosed
and corrected.
NOTE: The ESP Control System will make buzzing or
clicking sounds when it is active. This is normal; the sound will stop when the ESP becomes inactive following
a maneuver that caused the ESP activation.
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!
Driving with a hot engine cooling system could
damage your vehicle. If temperature gauge reads “H”
pull over and stop the vehicle. Idle the vehicle with
the air conditioner turned off until the pointer drops
back into the normal range. If the pointer remains on
the “H” and you hear continuous chimes, turn the
engine off immediately, and call an authorized deal-
ership for service.

Fuel Cap Fault Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, the
words “gASCAP” will display in the odometer. If this
occurs, tighten the fuel filler cap properly and press the
odometer reset button to turn off the message. If the
problem continues, the message will appear the next time
the vehicle is started.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the Malfunction Indicator Light (MIL).
Change Oil Message (Base And Mid Line Clusters
Only)
Your vehicle is equipped with an engine oil change
indicator system. The “CHANgE OIL” message will flash
in the instrument cluster odometer for approximately
12 seconds after a single chime has sounded to indicate
the next scheduled oil change interval. The engine oil
change indicator system is duty cycle based, whichmeans the engine oil change interval may fluctuate
dependent upon your personal driving style.
Unless reset, this message will continue to display each
time you turn the ignition switch to the ON position. To
turn off the message temporarily, press and release the
Trip Odometer button on the instrument cluster. To reset
the oil change indicator system (after performing the
scheduled maintenance) perform the following proce-
dure:
1. Turn the ignition switch to the ON position. Do not
start the engine.
2. Fully depress the accelerator pedal slowly three
times within 10 seconds.
3. Turn the ignition switch to the LOCK position.
NOTE: If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary, repeat this procedure.
