2023 JEEP COMPASS transmission

112STARTING AND OPERATING
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the
transmission will return to normal operation.
NOTE:Even if the transmission can be reset, we
recommend that you visit an authorized dealer at
your earliest possible convenience. An authorized
dealer has diagnostic equipment to assess the
condition of your transmission. 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 transmission 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
accelerations, the clutch automatically
disengages.
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 engaged, 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 conditions, 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 traction 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.
Four-Wheel Drive (4x4)
The four-wheel drive (4WD) is fully automatic in
normal driving mode.
NOTE:It is not possible to carry out the change of mode
when the vehicle exceeds the speed of 75 mph
(120 km/h).

4WD Buttons

Enabling Four-Wheel Drive (4x4)
The buttons for the activation of four-wheel drive
are located on the center console and allow you to
select the following:
4WD LOCK
4WD LOW — (Trailhawk models only)
CAUTION!
All wheels must have the same size and type
tires. Unequal tire sizes must not be used.

please follow the steps below:
Enabling 4WD LOW
With the vehicle stationary, the ignition in the ON/
RUN position or with the engine running, shift the
transmission into NEUTRAL and push the 4WD
LOW button once. The instrument cluster will
display the message “4WD LOW” once the shift is
complete.
NOTE:
Both LOCK and LOW LED lights will blink and
then become active on the buttons until the
shift is complete.
The instrument cluster display will illuminate the
4WD LOW icon. Disabling 4WD LOW
To disable the 4WD LOW mode, the vehicle must
be stationary and the transmission shifted into
NEUTRAL. Push the 4WD LOW button once.
SELEC-TERRAIN — IF EQUIPPED
Selec-Terrain combines the capabilities of the
vehicle control systems, along with driver input, to
provide the best performance for all terrains.
MODE SELECTION GUIDE

Selec-Terrain Switch

AUTO
: This four-wheel drive operation is a
continuous operation, is fully automatic and can
be used on and off road. This mode balances
traction to ensure maneuverability and acceler -
ation improvement compared to a vehicle with
two wheel drive. This mode also reduces fuel consumption, since it allows the disconnect of
the drive shaft where conditions permit.
SNOW
: This mode allows you to have greater
stability under conditions of bad weather. For
use on and off road on surfaces with poor trac-
tion, such as roads covered with snow. When in
SNOW mode (depending on certain operating
conditions), the transmission may use SECOND
gear (rather than FIRST gear) during launches,
to minimize wheel slippage.
SAND/MUD : For off-road driving or use on
surfaces with poor traction, such as dry sand
and roads covered by mud or wet grass. The
transmission is set to provide maximum trac -
tion.
ROCK : (Trailhawk only): This mode is only avail -
able in 4WD LOW range. The device sets the
vehicle to maximize traction and allow the
highest steering capacity for off-road surfaces.
This mode gives you the maximum performance
off-road. Use for low speed obstacles such as
large rocks, deep ruts, etc.
SPORT : This mode is only available in 4WD
AUTO, and alters the transmission's automatic
shift schedule for sportier driving. Upshift
speeds are increased to make full use of avail -
able engine power. Suspension settings are
optimized and steering assist is modified to
provide better handling performance.

HVAC system temperature or fan speed is
manually adjusted.
Battery voltage drops too low.
Stop/Start OFF switch is pressed.
A Stop/Start system error occurs.
Vehicle is in 4WD LOW transfer case mode.
Conditions That Force An Application Of The
Electric Park Brake While In Autostop Mode:
The driver’s door is open and brake pedal
released.
The driver’s door is open and the driver’s seat
belt is unbuckled.
The engine hood has been opened.

Metric Speed (km/h)
Pushing the SET (+) , or SET (-) button once will
result in a 1 km/h speed adjustment. Each
subsequent tap of the button results in an
adjustment of 1 km/h.
If the button is continually pushed, the set
speed will continue to adjust until the button is
released, then the new set speed will be estab -
lished.
To Accelerate For Passing
While the Cruise Control is set, press the
accelerator to pass as you would normally. When
the pedal is released, the vehicle will return to the
set speed.
USING CRUISE CONTROL ON HILLS
The transmission may downshift on hills to
maintain the vehicle set speed.
The Cruise Control system maintains speed up and
down hills. A slight speed change on moderate hills
is normal. On steep hills, a greater speed loss or
gain may occur so it may be preferable to drive
without Cruise Control.
To Resume Speed
To resume a previously set speed, push the RES
button and release. Resume can be used at any
speed above 20 mph (32 km/h).
To Deactivate
A tap on the brake pedal, or pushing the CANC
button, or normal brake pressure will deactivate
the Cruise Control system without erasing the set
speed from memory.
The following conditions will also deactivate the
Cruise Control without erasing the set speed from
memory:
Vehicle parking brake is applied
Stability event occurs
Gear selector is moved out of DRIVE
Engine overspeed occurs
Pushing the on/off button or placing the ignition in
the OFF position, will erase the set speed from
memory.
ADAPTIVE CRUISE CONTROL (ACC)
Adaptive Cruise Control (ACC) increases the driving
convenience provided by Cruise Control while
traveling on highways and major roadways.
However, it is not a safety system and not designed
to prevent collisions. The Cruise Control function
performs differently if your vehicle is not equipped
with ACC Ú page 117.
ACC will allow you to keep Cruise Control engaged
in light to moderate traffic conditions without the
constant need to reset your speed. ACC utilizes a
radar sensor and a forward facing camera
designed to detect a vehicle directly ahead of you
to maintain a set speed.
NOTE:
If the ACC sensor detects a vehicle ahead, ACC
will apply limited braking or accelerate (not to
exceed the original set speed) automatically to
maintain a preset following distance, while
matching the speed of the vehicle ahead.
Any chassis/suspension or tire size modifica -
tions to the vehicle will affect the performance
of the Adaptive Cruise Control and Forward Colli -
sion Warning system.
Fixed Speed Cruise Control (ACC not enabled)
will not detect vehicles directly ahead of you.
Always be aware of the feature selected
Ú page 328.
WARNING!

Cruise Control can be dangerous where the
system cannot maintain a constant speed. Your
vehicle could go too fast for the conditions, and
you could lose control and have an accident. Do
not use Cruise Control in heavy traffic or on roads
that are winding, icy, snow-covered or slippery.

STARTING AND OPERATING155
Trailer Sway Control (TSC)
The TSC can be a mechanical telescoping link that
can be installed between the hitch receiver and the
trailer tongue that typically provides adjustable
friction associated with the telescoping motion to
dampen any unwanted trailer swaying motions
while traveling.
If equipped, the electronic TSC recognizes a
swaying trailer and automatically applies individual
wheel brakes and/or reduces engine power to
attempt to eliminate the trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue
weight, just as if it were luggage located at a hitch
ball or some other connecting point of the vehicle. These kinds of hitches are commonly used to tow
small and medium sized trailers.
Weight-Distributing Hitch
A Weight-Distributing system works by applying
leverage through spring (load) bars. They are
typically used for heavier loads to distribute trailer
tongue weight to the tow vehicle's front axle and
the trailer axle(s). When used in accordance with
the manufacturer's directions, it provides for a
more level ride, offering more consistent steering
and brake control thereby enhancing towing
safety. The addition of a friction/hydraulic sway
control also dampens sway caused by traffic and
crosswinds and contributes positively to tow
vehicle and trailer stability. Trailer sway control and
a Weight-Distributing (load equalizing) Hitch are recommended for heavier Tongue Weights (TW)
and may be required depending on vehicle and
trailer configuration/loading to comply with Gross
Axle Weight Rating (GAWR) requirements.
TRAILER TOWING WEIGHTS (MAXIMUM TRAILER WEIGHT RATINGS)
WARNING!
An improperly adjusted Weight-Distributing
Hitch system may reduce handling, stability,
braking performance, and could result in a
collision.
Weight-Distributing systems may not be
compatible with surge brake couplers. Consult
with your hitch and trailer manufacturer or a
reputable Recreational Vehicle dealer for
additional information.

Towing Requirements — Tires
Do not attempt to tow a trailer while using a
compact spare tire.
Do not drive more than 50 mph (80 km/h) when
towing while using a full size spare tire.
Proper tire inflation pressures are essential to
the safe and satisfactory operation of your
vehicle.
Check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire
damage before towing a trailer.
Replacing tires with a higher load carrying
capacity will not increase the vehicle's GVWR
and GAWR limits.
For further information Úpage 298.
Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake system
or vacuum system of your vehicle with that of
the trailer. This could cause inadequate braking
and possible personal injury.
An electronically actuated trailer brake
controller is required when towing a trailer with
electronically actuated brakes. When towing a
trailer equipped with a hydraulic surge actuated
brake system, an electronic brake controller is
not required.
Trailer brakes are recommended for trailers
over 1,000 lb (453 kg) and required for trailers
in excess of 2,000 lb (907 kg).
Vehicles with trailers should not be parked on
a grade. When parking, apply the parking
brake on the tow vehicle. Put the tow vehicle
transmission in PARK. For four-wheel drive
vehicles, make sure the transfer case is not in
NEUTRAL. Always, block or "chock" the trailer
wheels.
GCWR must not be exceeded.
Total weight must be distributed between the
tow vehicle and the trailer such that the
following four ratings are not exceeded :
GVWR
GTW
GAWR
Tongue weight rating for the trailer hitch
utilized.
