engine JEEP COMPASS 2009 1.G Service Manual

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
5

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.
STARTING AND OPERATING 255

To maintain a safe speed and prolong brake life, shift
down to 2nd or 1st gear when descending a steep grade.
When turning a corner or driving up a steep grade,
downshift early so that the engine will not be
overburdened.
AUTOMATIC TRANSAXLE — IF EQUIPPED
NOTE:The Continuously Variable Automatic Transaxle
(CVT) changes ratios in a continuous manner. This may
sometimes “feel” as if it is slipping, but this is normal and
does not harm anything.
CAUTION!
Damage to the transaxle may occur if the following
precautions are not observed:
•Shift into PARK only after the vehicle has come to
a complete stop.
•Shift into or out of REVERSE only after the
vehicle has come to a complete stop and the engine
is at idle speed.
•Do not shift from REVERSE, PARK, or NEUTRAL
into any forward gear when the engine is above
idle speed.
•Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
NOTE:You MUST press and hold the brake pedal down
while shifting out of PARK.
256 STARTING AND OPERATING

WARNING!
It is dangerous to move the shift lever out of PARK or
NEUTRAL if the engine speed is higher than idle
speed. If your foot is not firmly on the brake pedal,
the vehicle could accelerate quickly forward or in
reverse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when the
engine is idling normally and when your right foot is
firmly on the brake pedal.
Brake/Transmission Interlock System
This system prevents you from moving the shift lever out
of PARK and into any gear unless the brake pedal is
pressed. This system is active only while the ignition
switch is in the ON or ACC positions. Always depress the
brake pedal first,before moving the shift lever out of
PARK.NOTE:If a malfunction occurs, the transaxle will not
shift out of PARK. Battery power is required to release the
brake/transmission interlock system. There is a remov-
able plug in the right side of the shift lever housing that
allows you to insert your finger to override the system.
The key must be in the ignition and in the ON position to
use the override lever. If this occurs obtain service as
soon as possible.
Automatic Transaxle Ignition Interlock System
This system prevents the key from being removed unless
the shift lever is in PARK. It also prevents shifting out of
PARK unless the key is in the ACC or ON position, and
the brake pedal is depressed.
NOTE:If a malfunction occurs, the system will trap the
key in the ignition cylinder to warn you that this safety
feature is inoperable. The engine can be started and
stopped, but the key cannot be removed, until you obtain
service.
STARTING AND OPERATING 257

Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL positions into another gear range.
PARK
Supplements the parking brake by locking the transmis-
sion. The engine can be started in this range. Never usePARK while the vehicle is in motion. Apply the parking
brake when leaving the vehicle in this range. Always
apply the parking brake first, and then place the shift
lever in the PARK position.
WARNING!
Unintended movement of a vehicle could injure
those in and near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, you should always
shift the vehicle into PARK, remove the key from the
ignition, and apply the parking brake. Once the key
is removed from the ignition, the shift lever is locked
in the PARK position, securing the vehicle against
unwanted movement. Furthermore, you should never
leave unattended children inside a vehicle.
Shift Lever
258 STARTING AND OPERATING

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.
STARTING AND OPERATING 259

AUTOSTICK— IF EQUIPPED
Autostickis a driver-interactive transmission that offers
six manual ratio changes to provide you with more
control. Autostickallows you to maximize engine brak-
ing, eliminate undesirable upshifts and downshifts, and
improve overall vehicle performance. This system can also
provide you with more control during passing, city driv-
ing, cold slippery conditions, mountain driving, trailer
towing, and many other situations. Automatic ratio
changes upward will only occur to protect the Continu-
ously Variable Automatic Transaxle (CVT) and/or the
engine from overspeed. Changes down will only happen
at minimum engine speed to prevent stalling.
Operation
NOTE:Autostickis not functional until the CVT
warms up in cold weather.
Autostickoperation is activated in the DRIVE position
by moving the shift lever side-to-side. Moving the shiftlever to the (+) side will activate Autostickand shift up
to the next higher manual ratio, unless you are already
operating in or near Overdrive, in which case 6th ratio
will be selected. In like manner, moving the shift lever to
(-) will activate Autostickand shift to the next lower
manual ratio. After Autostickis activated, the manual
ratio selected is displayed in the transmission ratio
display and tipping the shift lever to the (+) or (-)
direction will cause an upshift or downshift by one ratio.
Autostickis deactivated:
•By holding the shift lever to (+) momentarily
•When the shift lever is shifted out of DRIVE
•When in 6th position, touching the shift lever to the
right
•When heavy Anti-Lock Brake System (ABS) applica-
tion is detected
260 STARTING AND OPERATING

General Information
•
If a ratio other than 1st is selected and the vehicle is
brought to a stop, the transaxle control logic will
automatically select the 1st gear ratio.
•If a low range is selected and the engine accelerates to
the rev limit, the transaxle will automatically select the
next higher ratio.
•If a downshift would cause the engine to overspeed,
that shift will not occur until it is safe for the engine.
However. the CVT will stay in the manually selected
ratio.
•If the system detects powertrain overheating, the
transmission will revert to the automatic shift mode
and remain in that mode until the powertrain cools off.
•If the system detects a problem, it will disable the
Autostickmode and the transmission will return to
the automatic mode until the problem is corrected.
FOUR-WHEEL DRIVE OPERATION — IF
EQUIPPED
This feature provides full time, on-demand, four–wheel
drive (4WD).

Shallow Standing Water
Although your vehicle is capable of driving through
shallow standing water, consider the following Caution
and Warning before doing so.
CAUTION!
•Always check the depth of the standing water
before driving through it. Never drive through
standing water that is deeper than the bottom of
the tire rims mounted on the vehicle.
•Determine the condition of the road or the path
that is under water and if there are any obstacles in
the way before driving through the standing wa-
ter.
•Do not exceed 5 mph (8 km/h) when driving
through standing water. This will minimize wave
effects.
(Continued)
CAUTION! (Continued)
•Driving through standing water may cause dam-
age to your vehicle’s drivetrain components. Al-
ways inspect your vehicle’s fluids (i.e., engine oil,
transmission/transaxle, axle, etc.) for signs of con-
tamination (i.e., fluid that is milky or foamy in
appearance) after driving through standing water.
Do not continue to operate the vehicle if any fluid
appears contaminated, as this may result in further
damage. Such damage is not covered by the New
Vehicle Limited Warranty.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and cause serious
internal damage to the engine. Such damage is not
covered by the New Vehicle Limited Warranty.
264 STARTING AND OPERATING

WARNING!
•Driving through standing water limits your vehi-
cle’s traction capabilities. Do not exceed 5 mph
(8 km/h) when driving through standing water.
•Driving through standing water limits your vehi-
cle’s braking capabilities, which increases stop-
ping distances. Therefore, after driving through
standing water, drive slowly and lightly press on
the brake pedal several times to dry the brakes.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and leave you
stranded.
•Failure to follow these warnings may result in
injuries that are serious or fatal to you, your
passengers, and others around you.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.
If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:Increased noise levels at the end of the steering
wheel travel are considered normal and do not indicate
that there is a problem with the power steering system.
Upon initial start-up in cold weather, the power steering
pump may make noise for a short amount of time. This is
due to the cold, thick fluid in the steering system. This
noise should be considered normal, and it does not in any
way damage the steering system.
