2018 JEEP COMPASS service

Operation
When the gear selector is in the AutoStick
position (beside the DRIVE position), it can
be moved forward and rearward. This allows
the driver to manually select the transmission
gear being used. Moving the gear selector
forward (-) triggers a downshift and rearward
(+) an upshift. The current gear is displayed
in the instrument cluster.
In AutoStick mode, the transmission will
shift up or down when the driver moves the
gear selector rearward (+) or forward (-), un-
less an engine lugging or overspeed condition
would result. It will remain in the selected
gear until another upshift or downshift is
chosen, except as described below.
• Six-speed transmissions will automatically
upshift when necessary to prevent engine
over-speed.
• The transmission will automatically down-
shift as the vehicle slows (to prevent engine
lugging) and will display the current gear.• The transmission will automatically down-
shift to first gear when coming to a stop.
After a stop, the driver should manually
upshift (+) the transmission as the vehicle
is accelerated.
• You can start out, from a stop, in first or
second gear (or third gear, in six-speed
models, or in 4LO range, Snow mode, or
Sand mode, where available). Tapping (+)
(at a stop) will allow starting in second gear.
Starting out in second gear can be helpful
in snowy or icy conditions.
• If a requested downshift would cause the
engine to over-speed, that shift will not
occur.
• The system will ignore attempts to upshift
at too low of a vehicle speed.
• Transmission shifting will be more notice-
able when AutoStick is enabled.
• The system may revert to automatic shift
mode if a fault or overheat condition is
detected.
NOTE:
When Selec-Speed or Hill Descent Control is
enabled, AutoStick is not active.To disengage AutoStick, return the gear se-
lector to the DRIVE position. You can shift in
or out of the AutoStick position at any time
without taking your foot off the accelerator
pedal.
WARNING!
Do not downshift for additional engine
braking on a slippery surface. The drive
wheels could lose their grip and the ve-
hicle could skid, causing a collision or
personal injury.
Transmission Limp Home Mode
Transmission function is monitored electroni-
cally for abnormal conditions. If a condition
is detected that could result in transmission
damage, Transmission Limp Home Mode is
activated. In this mode, the transmission
may operate only in a fixed gear, or may
remain in NEUTRAL. The Malfunction Indi-
cator Light (MIL) may be illuminated. Limp
Home Mode may allow the vehicle to be
driven to an authorized dealer for service
without damaging the transmission.
STARTING AND OPERATING
156

In the event of a momentary problem, the
transmission can be reset to regain all for-
ward gears by performing the following steps:
1. Stop the vehicle.
2. Shift the transmission into PARK, if pos-
sible. If not, shift the transmission to
NEUTRAL.
3. Turn the ignition to the OFF position. On
vehicles with push button start, push and
hold the ignition until the engine turns
OFF.
4. Wait approximately 30 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the
problem is no longer detected, the trans-
mission will return to normal operation.
NOTE:
Even if the transmission can be reset, we
recommend that you visit your authorized
dealer at your earliest possible convenience.
Your authorized dealer has diagnostic equip-
ment to assess the condition of your trans-
mission. If the transmission cannot be reset,
authorized dealer service is required.Torque Converter Clutch
A feature designed to improve fuel economy
has been included in the automatic transmis-
sion on your vehicle. A clutch within the
torque converter engages automatically at
calibrated speeds. This may result in a
slightly different feeling or response during
normal operation in the upper gears. When
the vehicle speed drops or during some ac-
celerations, the clutch automatically disen-
gages.
NOTE:
The torque converter clutch will not engage
until the engine and/or transmission is warm
(usually after 1 to 3 miles [2 to 5 km] of
driving). Because the engine speed is higher
when the torque converter clutch is not en-
gaged, it may seem as if the transmission is
not shifting properly when the vehicle is cold.
This is normal. The torque converter clutch
will function normally once the powertrain is
sufficiently warm.FOUR-WHEEL DRIVE
OPERATION — IF EQUIPPED
Jeep Active Drive
Your vehicle may be equipped with a Power
Transfer Unit (PTU). This system is automatic
with no driver inputs or additional driving
skills required. Under normal driving condi-
tions, the front wheels provide most of the
traction. If the front wheels begin to lose
traction, power is shifted automatically to the
rear wheels. The greater the front wheel trac-
tion loss, the greater the power transfer to the
rear wheels.
Additionally, on dry pavement under heavy
throttle input (where one may have no wheel
spin), torque will be sent to the rear in a
preemptive effort to improve vehicle launch
and performance characteristics.

ParkSense Sensors
The four ParkSense sensors, located in the
rear fascia/bumper, monitor the area behind
the vehicle that is within the sensors’ field of
view. The sensors can detect obstacles from
approximately 12 inches (30 cm) up to
79 inches (200 cm) from the rear fascia/
bumper in the horizontal direction, depend-
ing on the location, type and orientation of
the obstacle.
Enabling And Disabling ParkSense
ParkSense can be enabled and disabled with
the ParkSense switch, located on the switch
panel below the Uconnect display.When the ParkSense switch is pushed to
disable the system, the instrument cluster
display will show the “PARKSENSE OFF”
message for approximately five seconds. Re-
fer to “Instrument Cluster Display” in “Get-
ting To Know Your Instrument Panel” in your
Owner’s Manual for further details. When the
gear selector is moved to REVERSE and the
system is disabled, the instrument cluster
display will show the “PARKSENSE OFF”
message for as long as the vehicle is in
REVERSE.
The ParkSense switch LED will be on when
ParkSense is disabled or requires service.
The ParkSense switch LED will be off when
the system is enabled. If the ParkSense
switch is pushed, and requires service, the
ParkSense switch LED will blink momen-
tarily, and then the LED will be on.
Instrument Cluster Display — Warning
The ParkSense Warning screen will only be
displayed if Sound and Display is selected
from the Customer - Programmable Features
section of the Uconnect System. Refer to
"Uconnect Settings” in “Multimedia” in your
Owner's Manual for further information.The ParkSense Warning screen is located
within the instrument cluster display. It pro-
vides visual warnings to indicate the distance
between the rear fascia/bumper and the de-
tected obstacle. Refer to “Instrument Cluster
Display” in your Owner's Manual for further
information.
ParkSense System Usage Precautions
NOTE:
• Ensure that the rear bumper is free of snow,
ice, mud, dirt and debris to keep the
ParkSense system operating properly.
• Jackhammers, large trucks, and other vi-
brations could affect the performance of
ParkSense.
• When you turn ParkSense OFF, the instru-
ment cluster display will read
“PARKSENSE OFF” Furthermore, once you
turn ParkSense OFF, it remains off until you
turn it on again, even if you cycle the
ignition.
• ParkSense, when on, will reduce the vol-
ume of the radio when it is sounding a tone.

• Clean the ParkSense sensors regularly, tak-
ing care not to scratch or damage them. The
sensors must not be covered with ice, snow,
slush, mud, dirt or debris. Failure to do so
can result in the system not working prop-
erly. The ParkSense system might not de-
tect an obstacle behind the fascia/bumper,
or it could provide a false indication that an
obstacle is behind the fascia/bumper.
• Use the ParkSense switch to turn the
ParkSense system OFF if objects such as
bicycle carriers, trailer hitches, etc. are
placed within 12 inches (30 cm) from the
rear fascia/bumper. Failure to do so can
result in the system misinterpreting a close
object as a sensor problem, causing the
“PARKSENSE UNAVAILABLE SERVICE
REQUIRED” message to be displayed in
the instrument cluster display.
• The operation of the rear sensors is auto-
matically deactivated when the trailer's
electric plug is inserted in the vehicle's tow
hook socket. The rear sensors are automati-
cally reactivated when the trailer's cable
plug is removed.WARNING!
• Drivers must be careful when backing up
even when using ParkSense. Always
check carefully behind your vehicle, look
behind you, and be sure to check for
pedestrians, animals, other vehicles, ob-
structions, and blind spots before back-
ing up. You are responsible for safety
and must continue to pay attention to
your surroundings. Failure to do so can
result in serious injury or death.
• Before using ParkSense, it is strongly
recommended that the ball mount and
hitch ball assembly is disconnected
from the vehicle when the vehicle is not
used for towing. Failure to do so can
result in injury or damage to vehicles or
obstacles because the hitch ball will be
much closer to the obstacle than the rear
fascia when the loudspeaker sounds the
continuous tone. Also, the sensors could
detect the ball mount and hitch ball
assembly, depending on its size and
shape, giving a false indication that an
obstacle is behind the vehicle.
CAUTION!
• ParkSense is only a parking aid and it is
unable to recognize every obstacle, in-
cluding small obstacles. Parking curbs
might be temporarily detected or not
detected at all. Obstacles located above
or below the sensors will not be detected
when they are in close proximity.
• The vehicle must be driven slowly when
using ParkSense in order to be able to
stop in time when an obstacle is de-
tected. It is recommended that the
driver looks over his/her shoulder when
using ParkSense.

NOTE:
If your vehicle is equipped with the
ParkSense Active Park Assist system, six sen-
sors will be located in the rear fascia/bumper.
Refer to the "ParkSense Active Park Assist
System" section for further information.
The six ParkSense sensors, located in the
front fascia/bumper, monitor the area in front
of the vehicle that is within the sensors’ field
of view. The sensors can detect obstacles
from approximately 12 inches (30 cm) up to
47 inches (120 cm) from the front fascia/
bumper in the horizontal direction, depend-
ing on the location, type and orientation of
the obstacle.

WARNING!
• When replacing a blown fuse, always use
an appropriate replacement fuse with
the same amp rating as the original fuse.
Never replace a fuse with another fuse of
higher amp rating. Never replace a
blown fuse with metal wires or any other
material. Do not place a fuse inside a
circuit breaker cavity or vice versa. Fail-
ure to use proper fuses may result in
serious personal injury, fire and/or prop-
erty damage.
• Before replacing a fuse, make sure that
the ignition is off and that all the other
services are switched off and/or disen-
gaged.
• If the replaced fuse blows again, contact
an authorized dealer.
• If a general protection fuse for safety
systems (air bag system, braking sys-
