clutch JEEP COMPASS 2017 2.G User Guide

NOTE:Engagement of the torque converter clutch is in-
hibited at very cold temperatures. Because the engine
speed is higher when the torque converter clutch is not
engaged, it may seem as if the transmission is not shifting
into Overdrive when cold. This is normal. The torque
converter clutch will function normally once the transmis-
sion is sufficiently warm.
Continuously Variable Automatic Transmission
(CVT) — If Equipped
The transmission gear position display (located in the
instrument cluster) indicates the transmission gear range.
You must press the brake pedal to move the gear selector
out of PARK (refer to “Brake/Transmission Shift Interlock
System” in this section). To drive, move the gear selector
from PARK or NEUTRAL to the DRIVE position.
NOTE: The Continuously Variable Automatic Transmis-
sion (CVT) changes ratios in a continuous manner. This
may sometimes feelas if it is slipping, but this is normal
and does not harm anything.
Only shift from DRIVE to PARK or REVERSE when the
accelerator pedal is released and the vehicle is stopped. Be
sure to keep your foot on the brake pedal when shifting
between these gears. The transmission gear selector has only PARK, REVERSE,
NEUTRAL, and DRIVE shift positions. Manual shifts can
be made using the AutoStick shift control (refer to
AutoStick
in this section). Moving the gear selector to the
left or right (-/+) while in the DRIVE position will manu-
ally select from a set of predefined transmission gear ratios,
and will display the current gear in the instrument cluster
as 1, 2, 3, etc.
Gear Ranges
DO NOT race the engine when shifting from PARK or
NEUTRAL into another gear range.
NOTE: After selecting any gear range, wait a moment to
allow the selected gear to engage before accelerating. This
is especially important when the engine is cold.
PARK (P)
This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while the vehicle is in motion.
Apply the parking brake when leaving the vehicle in this
range.
When parking on a level surface, you may shift the
transmission into PARK first, and then apply the parking
brake.6
STARTING AND OPERATING 211

Towing Tips
Before setting out on a trip, practice turning, stopping, and
backing up the trailer in an area located away from heavy
traffic.
Manual Transmission — If Equipped
If using a manual transmission vehicle for trailer towing,
all starts must be in first gear to avoid excessive clutch
slippage.
Automatic Transmission — If Equipped
The DRIVE range can be selected when towing. However,
if frequent shifting or changes in engine speed occur while
in this range, use the AutoStick shift control (if equipped)
to select a lower gear ratio.
NOTE:
•Using a lower gear ratio while operating the vehicle
under heavy loading conditions, will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat buildup. This action will also
provide better engine braking.
• If you REGULARLY tow a trailer for more than 45
minutes of continuous operation, then change the trans-
mission fluid and filter as specified for police, taxi, fleet,
or frequent trailer towing. Refer to the Maintenance
Plan for the proper maintenance intervals.

4. Turn the ignition switch to the ACC or ON/RUNposition, but do not start the engine.
5. Press and maintain firm pressure on the brake pedal.
6. Insert the screwdriver or similar tool into the access port, and push and hold the override release lever
forward.
7. Move the gear selector to the NEUTRAL position.
8. The vehicle may then be started in NEUTRAL.
9. Reinstall the gear selector override access cover.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it can
often be moved using a rocking motion. Turn the steering
wheel right and left to clear the area around the front
wheels. Then shift back and forth between DRIVE and
REVERSE (with automatic transmission) or 2nd gear and
REVERSE (with manual transmission), while gently press-
ing the accelerator. Use the least amount of accelerator
pedal pressure that will maintain the rocking motion,
without spinning the wheels, or racing the engine.
CAUTION!
Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine to idle with the transmission in NEUTRAL for at
least one minute after every five rocking-motion
cycles. This will minimize overheating and reduce the
risk of clutch or transmission failure during prolonged
efforts to free a stuck vehicle.

CAUTION!
•DO NOT flat tow any disabled vehicle if condition is
related to the clutch, transmission or driveline. Ad-
ditional damage to the drivetrain could result.
• Towing this vehicle in violation of the above require-
ments can cause severe engine, transmission, or
drivetrain damage. Damage from improper towing is
not covered under the New Vehicle Limited War-
ranty.
All Transmissions
If you must use the accessories (wipers, defroster, etc.)
while being towed, the key must be in the ON/RUN
position, not the ACC position. Make certain the transmis-
sion remains in NEUTRAL.
CAUTION!
•Do not use sling-type equipment when towing. Ve-
hicle damage may occur.
• When securing the vehicle to a flatbed truck, do not
attach to front or rear suspension components. Dam-
age to your vehicle may result from improper towing. Without The Ignition Key
Special care must be taken when the vehicle is towed with
the ignition in the LOCK/OFF position. The only approved
method of towing without the ignition key is with a flatbed
truck. Proper towing equipment is necessary to prevent
damage to the vehicle.
ENHANCED ACCIDENT RESPONSE SYSTEM
(EARS)
This vehicle is equipped with an Enhanced Accident
Response System.
Please refer to “Supplemental Restraint System (SRS) — Air
Bags” in “Occupant Restraints” for further information on
the Enhanced Accident Response System (EARS) function.
EVENT DATA RECORDER (EDR)
This vehicle is equipped with an Event Data Recorder
(EDR). The main purpose of an EDR is to record, in certain
crash or near crash-like situations, such as an air bag
deployment or hitting a road obstacle, data that will assist
in understanding how a vehicle’s systems performed.
Please refer to “Supplemental Restraint System (SRS) —
Air Bags” in “Occupant Restraints” for further information
on the Event Data Recorder (EDR).

tection of your engine which contains aluminum com-
ponents.
• Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
• Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install ONLY
the correct type thermostat. Other designs may result in
unsatisfactory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically. Refer
to the “Maintenance Plan” for the proper maintenance
intervals.
WARNING!
Riding the brakes can lead to brake failure and possi-
bly a collision. Driving with your foot resting or riding
on the brake pedal can result in abnormally high brake

temperatures, excessive lining wear, and possible
brake damage. You would not have your full braking
capacity in an emergency.
Brake Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately if
the brake system warning light is on.
Be sure to clean the top of the master cylinder area before
removing the cap. If necessary, add fluid to bring the fluid
level up to the requirements described on the brake fluid
reservoir. Fluid level can be expected to fall as the brake
pads wear. The brake fluid level should be checked when
the pads are replaced. However, low fluid level may be
caused by a leak and a checkup may be needed.
NOTE:If your vehicle is equipped with a manual trans-
mission, the brake fluid reservoir supplies fluid to both the
brake system and the clutch release system. The two
systems are separated in the reservoir, and a leak in one
system will not affect the other system. The manual
transmission clutch release system should not require fluid
replacement during the life of the vehicle. If the brake fluid

reservoir is low and the brake system does not indicate any
leaks or other problems, it may be a result of a leak in the
hydraulic clutch release system. See your local authorized
dealer for service.
Use only manufacturer’s recommended brake fluid. Refer
to “Fluids And Lubricants” in “Technical Specifications”
for further information.
WARNING!
•Use only manufacturer’s recommended brake fluid.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information. Using the
wrong type of brake fluid can severely damage your
brake system and/or impair its performance. The
proper type of brake fluid for your vehicle is also
identified on the original factory installed hydraulic
master cylinder reservoir.
• To avoid contamination from foreign matter or mois-
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master cylin-
der reservoir cap secured at all times. Brake fluid in
a open container absorbs moisture from the air
resulting in a lower boiling point. This may cause it

WARNING! (Continued)
to boil unexpectedly during hard or prolonged brak-
ing, resulting in sudden brake failure. This could
result in a collision.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.
CAUTION!
Use of improper brake fluids will affect overall clutch
system performance. Improper brake fluids may dam-
age the clutch system resulting in loss of clutch func-
tion and the ability to shift the transmission.
