fuel JEEP COMPASS 2009 1.G User Guide

NOTE:The air conditioning compressor operates in
both Mix and Defrost even if the Air Conditioning
Snowflake button is not pressed. This dehumidifies the
air to help dry the windshield. To improve fuel economy,
use these modes only when necessary.
Air Outlets
The airflow from each of the instrument panel outlets can
be adjusted for direction and turned on or off to control
air flow.
NOTE:For maximum airflow to the rear seat passen-
gers, the center instrument panel outlets can be aimed, so
that the left center outlet is directed toward the right rear
passenger and the right center outlet is directed toward
the left rear passenger.
Fan Control
Use this control to regulate the
amount of air forced through the
system in any mode you select.
The fan speed increases as you
move the control from left (OFF)
to right.
NOTE:For vehicles equipped with Remote Start, the
climate controls will not function during Remote Start
operation if the fan control is left in the “O” (Off)
position.

250 STARTING AND OPERATING

Normal Starting
Normal starting of either a cold or a warm engine does
not require pumping or depressing the accelerator pedal.
Simply turn the ignition switch to the START position
and release when the engine starts. If the engine fails to
start within 15 seconds, turn the ignition switch to the
OFF 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 (Below20°F Or29°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
252 STARTING AND OPERATING

If Engine Fails to Start
If the engine fails to start after you have followed the
“Normal Starting” 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 “Normal Starting” pro-
cedure.
WARNING!
Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
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.
After Starting
The idle speed will automatically decrease as the engine
warms up.
STARTING AND OPERATING 253

For most city driving, you will find it easier to use only
the lower gears. For steady highway driving with light
accelerations, 5th gear is recommended.
Never drive with your foot resting on the clutch pedal,
and never try to hold the vehicle on a hill with the clutch
pedal partially engaged. This will cause abnormal wear
on the clutch.
Never shift into REVERSE until the vehicle has come to a
complete stop.
NOTE:During cold weather, until the transaxle lubri-
cant is warm, you may experience slightly higher shift
efforts. This is normal and not harmful to the transaxle.
Recommended Shift Speeds
To use your manual transaxle for optimal fuel economy,
it should be upshifted as listed in the following table.

Downshifting
Proper downshifting will improve fuel economy and
prolong engine life.
CAUTION!
If you skip more than one gear while downshifting
or downshift at too high a vehicle speed, you could
damage the engine, transmission, or clutch.

The following indicators should be used to ensure that
you have engaged the shift lever into the PARK position:
•When shifting into PARK, firmly move the shift lever
all the way forward until it stops.
•Look at the shift indicator window on the shift lever
bezel to ensure it is in the PARK position.
•You must depress the brake pedal to move the shift
lever out of the PARK position.
CAUTION!
Before moving the shift lever out of PARK, you must
turn the ignition from LOCK to ON so the steering
wheel and shift lever are released. Otherwise, dam-
age to the steering column or shift lever could result.
You must also depress the brake pedal.
REVERSE
Shift into this range only after the vehicle has come to a
complete stop.
NEUTRAL
The engine may be started in this range.
DRIVE
This should be used for most driving and provides the
best ratio for optimum drivability, fuel economy, and
performance.

WARNING! (Continued)
•Unequal tire pressures from one side of the ve-
hicle to the other can cause the vehicle to drift to
the right or left.
•Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
Economy
Improper inflation pressures can cause uneven wear
patterns to develop across the tire tread. These abnormal
wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Underinflation also increases tire
rolling resistance and results in higher fuel consumption.
Ride Comfort and Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Overinflation produces a jarring and uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on the
driver’s side “B” Pillar.
Some vehicles may have Supplemental Tire Pressure
Information for vehicle loads that are less than the
maximum loaded vehicle condition. These pressure con-
ditions will be found in the “Supplemental Tire Pressure
Information” section of this manual.
The pressure should be checked and adjusted as well as
inspecting for signs of tire wear or visible damage at least
once a month. Use a good quality pocket-type gauge to
check tire pressure. Do not make a visual judgement
when determining proper inflation. Radial tires may look
properly inflated even when they are underinflated.
STARTING AND OPERATING 289

CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warnings have been established for the tire size
equipped on your vehicle. Undesirable system
operation or sensor damage may result when us-
ing replacement equipment that is not of the same
size, type, and/or style. Aftermarket wheels can
cause sensor damage. Do not use aftermarket tire
sealants or balance beads if your vehicle is
equipped with a TPMS, as damage to the sensors
may result.
•After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure Moni-
toring Sensor.NOTE:
•The TPMS is not intended to replace normal tire care
and maintenance or to provide warning of a tire failure
or condition.
•The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
•Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.
•The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire gauge, even
if under-inflation has not reached the level to trigger
illumination of the Tire Pressure Monitoring Telltale
light.
300 STARTING AND OPERATING

4. For each subsequent ignition key cycle, a chime will
sound and the Tire Pressure Monitoring Telltale Light
will flash on and off for 75 seconds and then remain on
solid.
5. Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact spare
tire, the TPMS will update automatically and the Tire
Pressure Monitoring Telltale Light will turn OFF, as long
as no tire pressure is below the low-pressure warning
limit in any of the four active road tires. The vehicle may
need to be driven for up to 20 minutes above 15 mph
(25 km/h) in order for the TPMS to receive this
information.

FUEL REQUIREMENTS
Your vehicle is designed to meet all emis-
sion regulations and provide excellent fuel
economy when using high-quality regular
unleaded gasoline with an octane rating of
87. The use of premium gasoline is not
recommended. The use of premium gaso-
line will provide no benefit over high-quality regular
gasolines and, in some circumstances may result in
poorer performance.
