fuel JEEP COMPASS 2010 1.G User Guide

Compass/Temperature/Audio
Press and release the EVIC button to display one of eight
compass headings to indicate the direction the vehicle is
facing, the outside temperature, and the current radio
station.
For additional information regarding the compass, refer
to Personal Settings (Customer-Programmable Features).
Average Fuel Economy
Shows the average fuel economy since the last reset.
When the fuel economy is reset, the display will read
“RESET” or show dashes for two seconds. Then, the
history information will be erased, and the averaging will
continue from the last fuel reading before the reset.
Distance To Empty (DTE)
Shows the estimated distance that can be traveled with
the fuel remaining in the tank. This estimated distance isdetermined by a weighted average of the instantaneous
and average fuel economy, according to the current fuel
tank level. This is not resettable.
NOTE:
Significant changes in driving style or vehicle
loading will greatly affect the actual drivable distance of
the vehicle, regardless of the DTE displayed value.
When the DTE value is less than 30 miles (48 km)
estimated driving distance, the DTE display will change
to a text display of LOW FUEL. This display will
continue until the vehicle runs out of fuel. Adding a
significant amount of fuel to the vehicle will turn off the
LOW FUEL text and a new DTE value will be dis-
played, based on the current values in the DTE calcula-
tion and the current fuel tank level.Tire Pressure Monitor (TPM)
Refer to “Starting And Operating”, “Tire Pressure Moni-
toring System (TPMS)” for system operation.

NOTE:For all settings except full cold or full hot, there
is a difference in temperature between the upper and
lower outlets. The warmer air flows to the floor outlets.
This feature gives improved comfort during sunny but
cool conditions.
Floor Air is directed through the floor outlets with a
small amount flowing through the defrost and side
window demist outlets.
Mix Air is directed through the floor, defrost, and side
window demist outlets. This setting works best in
cold or snowy conditions that require extra heat to
the windshield. This setting is good for maintaining
comfort while reducing moisture on the windshield. Defrost
Air is directed through the windshield and side
window demist outlets. Use this mode with maxi-
mum blower and temperature settings for best wind-
shield and side window defrosting.
NOTE: The air conditioning compressor operates in
Mix, Defrost, or a blend of these modes, even if the Air
Conditioning (A/C) button is not pressed. This dehu-
midifies the air to help dry the windshield. To improve
fuel economy, use these modes only when necessary.
Recirculation Control Pressing the Recirculation Control button will
put the system in recirculation mode. This can
be used when outside conditions such as
smoke, odors, dust, or high humidity are
present. Activating recirculation will cause the LED in the
control button to illuminate.

276 STARTING AND OPERATING

Do notpress the accelerator. Turn the ignition switch to
the START position and release it as soon as the starter
engages. The starter motor will continue to run, and it
will disengage automatically when the engine is running.
If the engine fails to start, the starter will disengage
automatically in 10 seconds. If this occurs, turn the
ignition switch to the LOCK position, wait 10 to 15 sec-
onds, then repeat the “Normal Starting” procedure.
Normal Starting
Normal starting of either a cold or a warm engine does
not require pumping or pressing 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. Refer to
“Jump Starting” in “What To Do In Emergencies” for
further information.
Extreme Cold Weather (Below 20°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.
278 STARTING AND OPERATING

If Engine Fails to Start
If the engine fails to start after you have followed the
“Normal Starting” and “Extreme Cold Weather” proce-
dures, 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” procedure.
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.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the cord
to a standard 110-115 Volt AC electrical outlet with a
grounded, three-wire extension cord.

STARTING AND OPERATING 279

Use each gear in numerical order, do not skip a gear. Be
sure the transaxle is in first gear, (not third), when
starting from a standing position. Damage to the clutch
can result from starting in third gear.
For most city driving, you will find it easier to use only
the lower gears. For steady highway driving with light
accelerations, fifth 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.
Manual Transaxle Recommended Shift Speeds
Units in mph (km/h)
Engine Size Accel-
eration Rate 1to2 2to3 3to4 4to5
All En- gines Accel 14 (23) 23 (37) 29 (47) 45 (72)
Cruise 12 (19) 18 (29) 25 (40) 32 (52)
Downshifting
Proper downshifting will improve fuel economy and
prolong engine life.

STARTING AND OPERATING 281

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. Under-inflation also increases tire
rolling resistance and results in higher fuel consumption.
Ride Comfort and Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Over-inflation 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 under-inflated.
318 STARTING AND OPERATING

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.

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, as it will not provide any
benefit over regular gasoline in these engines.
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 gasoline contains oxygenates and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.
The manufacturer supports the use of reformulated gaso-
line. Properly blended reformulated gasoline will pro-
vide excellent performance and durability of engine and
fuel system components.
