2008 JEEP COMPASS catalytic converter

Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc. may illuminate the light 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 Malfunction Indicator Light 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.
NOTE:If this indicator comes on, it will brighten to
FULL DAYTIME INTENSITY and will not be dimmable.
26. Front Fog Light Indicator Light Ð If Equipped
This light shows when the front fog lights are ON.27. Electronic Stability Program (ESP) Indicator
Light/Traction Control System (TCS) Indicator Light Ð
If Equipped
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 ESP, or TCS Ð if
equipped.
28. Electronic Stability Program (ESP) Indicator Light
The malfunction lamp for the ESP is combined
with BAS. The yellow ªESP/BAS Warning
Lampº comes on when the ignition switch is
turned to the ªONº position. They should go
out with the engine running. If the ªESP/BAS Warning
Lampº comes on continuously with the engine running,
a malfunction has been detected in either the ESP or the
BAS system. If this light remains on after several ignition

start within 15 seconds, turn the ignition switch to the
ªOFFº position, wait 10 to 15 seconds, then repeat the
normal starting procedure.
WARNING!
Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
axle 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 discharged battery, booster cables
may be used to obtain a start from another vehicle.
This type of start can be dangerous if done improp-
erly, so follow the procedure carefully. See section 6
of this manual for jump starting instructions.
Extremely Cold Weather (below220ÉF or229ÉC)
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
If the engine fails to start after you have followed the
ªNORMAL STARTINGº procedure, it may be flooded.
Push the accelerator pedal all the way to the floor and
hold it there. Crank the engine for no more than 15
seconds. This should clear any excess fuel in case the
engine is flooded. Leave the ignition key in the ON
position, release the accelerator pedal and repeat the
ªNORMAL STARTINGº procedure.
228 STARTING AND OPERATING

²An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact your dealer for service assistance.
²The use of fuel additives which are now being sold as
octane enhancers is not recommended. Most of these
products contain high concentrations of methanol.
Fuel system damage or vehicle performance problems
resulting from the use of such fuels or additives is not
the responsibility of the manufacturer.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
²Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas which can kill.
Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle is
stopped in an open area with the engine running for
more than a short period, adjust the ventilation system
to force fresh, outside air into the vehicle.
278 STARTING AND OPERATING

JUMP-STARTING PROCEDURES DUE TO A LOW
BATTERY
WARNING!
Take care to avoid the radiator cooling fan whenever
the hood is raised. It can start anytime the ignition
switch is on. You can be hurt by the fan.
WARNING!
Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
axle cannot be started this way and may be damaged.
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 discharged
battery, booster cables may be used to obtain a start
from another vehicle. This type of start can be
dangerous if done improperly, so follow this proce-
dure carefully.

Catalytic Converter
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device.
Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.CAUTION!
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and the
vehicle.
