2009 JEEP COMPASS engine

To turn ESP on again, momentarily depress the ESP OFF
switch. This will restore the “ESP On” mode of operation.
NOTE:The “ESP OFF” message will display and an
audible chime will sound when the shift lever is placed
into the PARK position from any other position, and then
moved out of the PARK position. This will occur even if
the message was previously cleared.
WARNING!
With the ESP switched off, the enhanced vehicle
stability offered by ESP is unavailable. In an emer-
gency evasive maneuver, the ESP system will not
engage to assist in maintaining stability. “ESP Off”
mode is intended for off-highway or off-road use,
only.
ESP/BAS Warning Light and ESP/TCS Indicator
Light
The malfunction indicator for the ESP is combined with
the BAS indicator. The yellow “ESP/BAS Warning
Lamp” and the yellow “ESP/TCS Indicator Light” in the
instrument cluster both come on when the ignition
switch is turned to the ON position. They should both go
out with the engine running. If the “ESP/BAS Warning
Lamp” comes on continuously with the engine running,
a malfunction has been detected in either the ESP or BAS
system, or both. If this light remains on after several
ignition cycles, and the vehicle has been driven several
miles/kilometers at speeds greater than 30 mph
(48 km/h), see your authorized dealer as soon as possible
to have the problem diagnosed and corrected.
278 STARTING AND OPERATING

Compact Spare Tire — If Equipped
The compact spare is for temporary emergency use with
radial tires. It is engineered to be used on your style
vehicle only. Since this tire has limited tread life, the
original tire should be repaired (or replaced) and rein-
stalled at the first opportunity.
WARNING!
•Temporary use spare tires are for emergency use
only. With these tires, do not drive more than
50 mph (80 km/h).
•Temporary-use spare tires have limited tread life.
When the tread is worn to the tread wear indica-
tors, the temporary use spare tire needs to be
replaced.
•Be sure to follow the warnings which apply to
your spare. Failure to do so could result in spare
tire failure and loss of vehicle control.Do not install a wheel cover or attempt to mount a
conventional tire on the compact spare wheel, since the
wheel is designed specifically for the compact spare.
Do not install more than one compact spare tire/wheel
on the vehicle at any given time.
CAUTION!
Because of the reduced ground clearance, do not take
your vehicle through an automatic car wash with the
compact spare installed. Damage to the vehicle may
result.
Limited-Use Spare — If Equipped
The limited-use spare tire is for temporary emergency
use on your vehicle. This tire is identified by a limited-
use spare tire warning label located on the limited-use
spare tire and wheel assembly. This tire may look like the
original equipped tire on the front or rear axle of your
292 STARTING AND OPERATING

Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at high
speeds can cause damage and immediate service is required.
Poor quality gasoline can cause problems such as hard
starting, stalling and hesitations. If you experience these
symptoms, try another brand of gasoline (with the ap-
propriate octane rating for your engine) before consider-
ing service for the vehicle.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “reformulated gasoline”.
“Reformulated gasolines” contain oxygenates and are
specifically blended to reduce vehicle emissions and
improve air quality.
The manufacturer supports the use of “reformulated
gasolines”. Properly blended “reformulated gasolines”
will provide excellent performance and durability of
engine and fuel system components.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as 10% ethanol, MTBE, and ETBE. Oxygen-
ates are required in some areas of the country during the
winter months to reduce carbon monoxide emissions.
Fuels blended with these oxygenates may be used in
your vehicle.
CAUTION!
DO NOT use gasolines containing Methanol or E85
Ethanol. Use of these blends may result in starting
and drivability problems and may damage critical
fuel system components.
Problems that result from using methanol/gasoline
blends are not the responsibility of the manufacturer.
While MTBE is an oxygenate made from Methanol, it
does not have the negative effects of Methanol.
308 STARTING AND OPERATING

E-85 Usage In Non-Flex Fuel Vehicles
Non-FFV vehicles are compatible with gasoline contain-
ing 10% ethanol (E10). Gasoline with higher ethanol
content may void the vehicle’s warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symptoms:
•operate in a lean mode
•OBD II “Malfunction Indicator Light” on
•poor engine performance
•poor cold start and cold drivability
•increased risk for fuel system component corrosion
To fix a Non-FFV vehicle inadvertently fueled once with
E-85 perform the following:
•drain the fuel tank (see your authorized dealer)
•change the engine oil and oil filter
•disconnect and reconnect the battery to reset the
engine controller memory
More extensive repairs will be required for prolonged
exposure to E-85 fuel.
MMT In Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase the octane num-
ber. Gasolines blended with MMT offer no performance
advantage beyond gasolines of the same octane number
without MMT. Gasolines blended with MMT have been
shown to reduce spark plug life and reduce emission
system performance in some vehicles. The manufacturer
recommends using gasolines without MMT. Since the
MMT content of gasoline may not be indicated on the
pump, you should ask your gasoline retailer whether or
not their gasoline contains MMT.
STARTING AND OPERATING 309

It is even more important to look for gasolines without
MMT in Canada, because MMT can be used at levels
higher than those allowed in the United States.
MMT is prohibited in Federal and California reformu-
lated gasolines.
Materials Added To Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and would result in additional cost. Therefore
you should not have to add anything to the fuel.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance
and damage the emission control system.
•An 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 authorized dealer for service assistance.
•The 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:
•Do 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 of time. 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.
•Guard against carbon monoxide with proper mainte-
nance. Have the exhaust system inspected every time
the vehicle is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with all side
windows fully open.
•Keep the liftgate closed when driving your vehicle to
prevent carbon monoxide and other poisonous ex-
haust gases from entering the vehicle.

NOTE:When the fuel nozzle “clicks” or shuts off, the
fuel tank is full.
WARNING!
•Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank filled.
•Never add fuel when the engine is running. This is
in violation of most state and Federal fire regula-
tions and will cause the Malfunction Indicator
Light (MIL) to turn on.
NOTE:Tighten the gas cap about 1/4 turn until you
hear one click. This is an indication that cap is properly
tightened.
If the gas cap is not tighten properly, the MIL will come
on. Be sure the gas cap is tightened every time the vehicle
is refueled.
WARNING!
A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on the
ground while filling.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose or improperly installed, a “gASCAP”
message will be displayed in the Odometer/Trip Odom-
eter in the instrument cluster. Refer to “Instrument
Cluster Description” in Section 4 of this manual. Tighten
the fuel filler cap properly and press the odometer/trip
odometer RESET button to turn the message off. If the
problem continues, the message will appear the next time
the vehicle is started. Refer to “Onboard Diagnostic
System — OBD II” in Section 7 of this manual for more
information.
