wheel size JEEP COMPASS 2023 Owners Manual

GETTING TO KNOW YOUR INSTRUMENT PANEL95
Each tire, including the spare (if provided), should
be checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire
inflation pressure label. If your vehicle has tires of
a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure
for those tires.
As an added safety feature, your vehicle has been
equipped with a TPMS that illuminates a low tire
pressure telltale when one or more of your tires is
significantly underinflated. Accordingly, when the
low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a
significantly underinflated tire causes the tire to
overheat and can lead to tire failure. Underinflation
also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if underinflation has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale. Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system
is not operating properly. The TPMS malfunction
indicator is combined with the low tire pressure
telltale. When the system detects a malfunction,
the telltale will flash for approximately one minute
and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists. When
the malfunction indicator is illuminated, the
system may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from
functioning properly. Always check the TPMS
malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
Towing Hook Breakdown Warning Light —
If Equipped
This light illuminates when there is a
failure with the tow hook. Contact an
authorized dealer for service.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warning have been established for the tire
size equipped on your vehicle. Undesirable
system operation or sensor damage may result
when using replacement equipment that is not
of the same size, type, and/or style. Aftermarket
wheels can cause sensor damage. Using
aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to
become inoperable. After using an aftermarket
tire sealant it is recommended that you take
your vehicle to an authorized dealer to have your
sensor function checked.

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.
Unequal tire size may cause failure of the Power
Transfer Unit.

(Continued)
NOTE:
It is the driver's responsibility to use the brake
and accelerator during the semi-automatic
parking maneuver.
It is the driver's responsibility to use the brake
and stop the vehicle. The driver should check
their surroundings and be prepared to stop the
vehicle either when instructed to, or when driver
intervention is required.
When the system instructs the driver to remove
their hands from the steering wheel, the driver
should check their surroundings and begin to
back up slowly.
The ParkSense Active Park Assist system will
allow a maximum of six shifts between DRIVE
and REVERSE. If the maneuver cannot be
completed within six shifts, the system will
cancel and the instrument cluster display will
instruct the driver to complete the maneuver
manually.
The system will cancel the maneuver if the
vehicle speed exceeds 5 mph (7 km/h) during
active steering guidance into the parking space.
The system will provide a warning to the driver
at 3 mph (5 km/h) that tells them to slow down.
The driver is then responsible for completing the
maneuver if the system is canceled.
If the system is canceled during the maneuver
for any reason, the driver must take control of
the vehicle.
WARNING!
Drivers must be careful when performing
parallel or perpendicular parking maneuvers
even when using the ParkSense Active Park
Assist system. Always check carefully behind
and in front of your vehicle, look behind and in
front of you, and be sure to check for pedes
-
trians, animals, other vehicles, obstructions,
and blind spots before backing up and moving
forward. 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 the ParkSense Active Park Assist
system, it is strongly recommended that the
ball mount and hitch ball assembly be discon -
nected 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
vehicle 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!
The ParkSense Active Park Assist system is
only a parking aid and it is unable to recognize
every obstacle, including 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.
WARNING!

STARTING AND OPERATING145
The sensors may not detect objects of a partic -
ular shape or made from particular materials
(very thin poles, trailer beams, panels, nets,
bushes, anti-parking posts, pavements, rubbish
bins, motor vehicles, etc.). Always take great
care to check that the vehicle and its path are
actually compatible with the parking place iden -
tified by the system.
The use of wheels and tires that are different
size to the original equipment could affect the
operation of the system.
The operation of the rear sensors is automati -
cally deactivated when the trailer's electric plug
is inserted in the vehicle's tow hook socket,
while the front sensors stay active and can
provide acoustic and visual warnings. If this situ -
ation occurs, Active Park Assist will not work.
The rear sensors are automatically reactivated
when the trailer's cable plug is removed.
In "Search in Progress" mode, the system could
incorrectly identify a parking place to carry out
the maneuver (e.g. by a junction, driveways,
roads crossing the direction of travel, etc.).
In the case of parking maneuvers on roads with
inclines, the performance of the system could
be inferior and it may deactivate.
If a parking maneuver is being carried out
between two parked vehicles alongside a curb,
the system may cause the vehicle to drive up
onto the curb.
Some maneuvers at very tight bends might be
impossible to be carried out.
Take great care to ensure that conditions do not
change during the parking maneuver (e.g. if
there are persons and/or animals in the parking
place, moving vehicles, etc.) and intervene
immediately if necessary.

During parking maneuvers, pay attention to vehi -
cles approaching from the opposite direction.
Always abide by the law and road regulations.

NOTE:
Correct system operation is not guaranteed if
snow chains or the compact spare tire are fitted.
The function only informs the driver about the
last appropriate parking place (parallel or
perpendicular) detected by the parking sensors.
Some messages displayed are accompanied by
acoustic warnings.
ACTIVE LANE MANAGEMENT SYSTEM —
IF EQUIPPED
ACTIVE LANE MANAGEMENT OPERATION
The Active Lane Management (ALM) system uses a
forward facing camera to detect lane markings or
road edges and measure vehicle position within
the lane boundaries. It also uses the Blind Spot Monitoring sensors to detect vehicles in adjacent
lanes while the driver is preparing to change lanes.
The system is operational at speeds above 37 mph
(60 km/h) and below 112 mph (180 km/h).
When both lane markings are detected, and the
vehicle drifts out of the lane (no turn signal
applied), the Active Lane Management system
provides a visual warning in the instrument cluster,
as well as a steering assist torque (if configured in
Uconnect Settings), to prompt the driver to remain
within the lane boundaries. If the driver continues
to drift out of the lane, the system provides a
flashing visual warning through the instrument
cluster display as well as a haptic steering wheel
vibration (if configured in Uconnect Settings) when
the vehicle crosses the lane boundary.
The warning will be in the form of a vibration in the
steering wheel, and/or automatic steering
assistance to direct the vehicle back toward the
center of the lane.
When both lane markings are detected, and the
driver uses the turn signal to indicate a lane
change while the system detects another vehicle in
the Blind Spot Monitoring zone on that side of the
vehicle, the Active Lane Management system
provides a warning in the form of steering assist
and/or steering vibration (depending on radio
settings) to guide the vehicle back to the center of
the lane.

the nozzle.
5. Remove the fuel nozzle and close the fuel door.
VEHICLE LOADING
CERTIFICATION LABEL
As required by National Highway Traffic Safety
Administration regulations, your vehicle has a
certification label affixed to the driver's side door or
pillar. This label contains the month and year of
manufacture, Gross Vehicle Weight Rating
(GVWR), front and rear Gross Axle Weight Rating
(GAWR), and Vehicle Identification Number (VIN).
A Month-Day-Hour (MDH) number is included on
this label and indicates the Month, Day and Hour of
manufacture. The bar code that appears on the
bottom of the label is your VIN.
Gross Vehicle Weight Rating (GVWR)

The GVWR is the total permissible weight of your
vehicle including driver, passengers, vehicle,
options and cargo. The label also specifies
maximum capacities of front and rear Gross Axle
Weight Rating (GAWR). Total load must be limited so
GVWR and front and rear GAWR are not exceeded.

Payload
The payload of a vehicle is defined as the allowable
load weight a truck can carry, including the weight
of the driver, all passengers, options and cargo.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the
front and rear axles. The load must be distributed
in the cargo area so that the GAWR of each axle is
not exceeded.
Each axle GAWR is determined by the components
in the system with the lowest load carrying capacity
(axle, springs, tires or wheels). Heavier axles or suspension components sometimes specified by
purchasers for increased durability does not
necessarily increase the vehicle's GVWR.
Tire Size
The tire size on the Vehicle Certification Label
represents the actual tire size on your vehicle.
Replacement tires must be equal to the load
capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire
size listed.
Inflation Pressure
This is the cold tire inflation pressure for your
vehicle for all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total
weight of the vehicle with all fluids, including
vehicle fuel, at full capacity conditions, and with no
occupants or cargo loaded into the vehicle. The
front and rear curb weight values are determined
by weighing your vehicle on a commercial scale
before any occupants or cargo are added.
Loading
The actual total weight and the weight of the front
and rear of your vehicle at the ground can best be
determined by weighing it when it is loaded and
ready for operation.
WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open or
the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the Malfunc
-
tion Indicator Light to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a vehicle.
You could be burned. Always place fuel
containers on the ground while filling.

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.

ESC Operating Modes
Depending upon model and mode of operation, the
ESC system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC.
Whenever the vehicle is started, the ESC system
will be in this mode. This mode should be used for
most driving conditions. Alternate ESC modes
should only be used for specific reasons as noted
in the following paragraphs.Partial Off
This mode may be useful if the vehicle becomes
stuck. This mode may modify TCS and ESC
thresholds for activation, which allows for more
wheel spin than normally allowed.
To enter the “Partial Off” mode, momentarily push
the ESC OFF button, located below the radio. The
ESC OFF Indicator Light will illuminate. To turn the
ESC on again, momentarily push the ESC OFF
button and the ESC OFF Indicator Light will turn off.
NOTE:
When driving with snow chains, or when starting off
in deep snow, sand, or gravel, it may be desirable to
allow more wheel spin. This can be accomplished by
momentarily pushing the ESC OFF button to enter
“Partial Off” mode. Once the situation requiring
“Partial Off” mode is overcome, turn ESC back on by
momentarily pushing the ESC OFF button. This may
be done while the vehicle is in motion.

Full Off (Four-Wheel Drive Models Only)
This mode is intended for off-highway or off-road
use when ESC stability features could inhibit
vehicle maneuverability due to trail conditions.
This mode is entered by pushing and holding the
ESC OFF button for five seconds when the vehicle
is stopped and the engine is running. After five
seconds, the ESC OFF Indicator Light will illuminate
and the “ESC OFF” message will appear in the
instrument cluster display.
In this mode, ESC and TCS, except for the “limited
slip” feature described in the TCS section, are
turned off until the vehicle reaches a speed of
40 mph (64 km/h). At 40 mph (64 km/h), the
system returns to “Partial Off” mode, as described
above. TCS remains off. When the vehicle speed
drops below 30 mph (48 km/h), the ESC system
shuts off. ESC is deactivated at low vehicle speeds
so that it will not interfere with off-road driving.
However, ESC function returns to provide the
stability feature at speeds above 40 mph
(64 km/h). The ESC OFF Indicator Light will always
be illuminated when ESC is off.
Vehicle modifications, or failure to properly
maintain your vehicle, may change the
handling characteristics of your vehicle, and
may negatively affect the performance of the
ESC system. Changes to the steering system,
suspension, braking system, tire type and size
or wheel size may adversely affect ESC perfor
-
mance. Improperly inflated and unevenly worn
tires may also degrade ESC performance. Any
vehicle modification or poor vehicle mainte -
nance that reduces the effectiveness of the
ESC system can increase the risk of loss of
vehicle control, vehicle rollover, personal
injury and death.
WARNING!
WARNING!
When in “Partial Off” mode, the TCS function -
ality of ESC, except for the limited slip feature
described in the TCS section, has been
disabled and the ESC OFF Indicator Light will
be illuminated. When in “Partial Off” mode,
the engine power reduction feature of TCS is
disabled, and the enhanced vehicle stability
offered by the ESC system is reduced.
Trailer Sway Control (TSC) is disabled when
the ESC system is in the “Partial Off” mode.

page 328.
NOTE:When filling warm tires, the tire pressure may need
to be increased up to an additional 4 psi (28 kPa)
above the recommended cold placard pressure in
order to turn the Tire Pressure Monitoring System
Warning Light off.
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 underinflated tire
causes the tire to overheat and can lead to tire
failure. Underinflation also reduces fuel effi -
ciency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility
to maintain correct tire pressure using an accu -
rate tire pressure gauge, even if underinflation
has not reached the level to trigger illumination
of the Tire Pressure Monitoring System Warning
Light.
Seasonal temperature changes will affect tire
pressure, and the TPMS will monitor the actual
tire pressure in the tire.
Premium System
The Tire Pressure Monitoring System (TPMS) uses
wireless technology with wheel rim mounted
electronic sensors to monitor tire pressure levels.
Sensors, mounted to each wheel as part of the
valve stem, transmit tire pressure readings to the
receiver module.
NOTE:It is particularly important for you to check the tire
pressure in all of the tires on your vehicle monthly
and to maintain the proper pressure.
The TPMS consists of the following components:
Receiver module
Four Tire Pressure Monitoring System sensors
Various Tire Pressure Monitoring System
messages, which will display in the instrument
cluster display
Tire Pressure Monitoring System Warning Light
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warning have been established for the tire
size equipped on your vehicle. Undesirable
system operation or sensor damage may
result when using replacement equipment
that is not of the same size, type, and/or style.
The TPMS sensor is not designed for use on
aftermarket wheels and may contribute to a
poor overall system performance or sensor
damage. Customers are encouraged to use
OEM wheels to ensure proper TPMS feature
operation.
Using aftermarket tire sealants may cause the
Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an
aftermarket tire sealant it is recommended
that you take your vehicle to an authorized
dealer to have your sensor function checked.
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 TPMS
sensor.

SAFETY203
Tire Pressure Monitoring System Low
Pressure Warnings

The Tire Pressure Monitoring System
Warning Light will illuminate in the
instrument cluster and a chime will sound
when tire pressure is low in one or more of
the four active road tires. In addition, the instrument
cluster will display a "Tire Low" message, an “Inflate
to XX” message, and a graphic showing the
pressure values of each tire with the low tire
pressure values highlighted or in a different color.

Tire Pressure Monitoring System Low Pressure Warning

Should this occur, you should stop as soon as
possible and inflate the tires with low pressure
(those highlighted or in a different color in the
instrument cluster display graphic) to the vehicle’s
recommended cold placard pressure value, as
shown in the “Inflate to XX” message. Once the
system receives the updated tire pressures, the system will automatically update, the pressure
values in the graphic display in the instrument
cluster will stop being highlighted or return to their
original color, and the Tire Pressure Monitoring
System Warning Light will turn off.
NOTE:When filling warm tires, the tire pressure may need
to be increased up to an additional 4 psi (28 kPa)
above the recommended cold placard pressure in
order to turn the Tire Pressure Monitoring System
Warning Light off.
The vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) in order for
the TPMS to receive this information.
Service TPMS Warning

When a system fault is detected, the Tire Pressure
Monitoring System Warning Light will flash on and
off for 75 seconds and then remain on solid. The
system fault will also sound a chime. In addition, the
instrument cluster will display a "SERVICE TPM
SYSTEM" message for a minimum of five seconds
and then display dashes (--) in place of the pressure
value to indicate which sensor is not being received.

If the ignition key is cycled, this sequence will
repeat, providing the system fault still exists. If the
system fault no longer exists, the Tire Pressure
Monitoring System Warning Light will no longer
flash, and the “SERVICE TPM SYSTEM” message
will no longer display, and a pressure value will
display in place of the dashes. A system fault can
occur due to any of the following:
Jamming due to electronic devices or driving
next to facilities emitting the same radio
frequencies as the TPMS sensors
Installing some form of aftermarket window
tinting that affects radio wave signals
Lots of snow or ice around the wheels or wheel
housings
Using tire chains on the vehicle
Using wheels/tires not equipped with TPMS
sensors
Vehicles With Compact Spare Or Non-Matching
Full Size Spare

1. The compact spare tire or non-matching full size does not have a Tire Pressure Monitoring
System sensor. Therefore, the TPMS will not
monitor the pressure in the compact or
non-matching full size spare tire.

2. If you install the compact or non-matching full size spare tire in place of a road tire that has a
pressure below the low-pressure warning limit,
upon the next ignition key cycle, the Tire
Pressure Monitoring System Warning Light will
remain on and a chime will sound. In addition,
the graphic in the instrument cluster will still
display a different color or highlighted pressure
value and the “Inflate to XX” message.
