2018 JEEP COMPASS maintenance

WARNING!
of an ERM-equipped vehicle must never
be exploited in a reckless or dangerous
manner which could jeopardize the user's
safety or the safety of others.
Electronic Stability Control (ESC)
This system enhances directional control and
stability of the vehicle under various driving
conditions. ESC corrects for oversteering or
understeering of the vehicle by applying the
brake of the appropriate wheel(s) to assist in
counteracting the oversteer or understeer
condition. Engine power may also be reduced
to help the vehicle maintain the desired path.
ESC uses sensors in the vehicle to determine
the vehicle path intended by the driver and
compares it to the actual path of the vehicle.
When the actual path does not match the
intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting
the oversteer or understeer condition.
• Oversteer — when the vehicle is turning
more than appropriate for the steering
wheel position.• Understeer — when the vehicle is turning
less than appropriate for the steering wheel
position.
The “ESC Activation/Malfunction Indicator
Light” located in the instrument cluster will
start to flash as soon as the ESC system
becomes active. The “ESC Activation/
Malfunction Indicator Light” also flashes
when the TCS is active. If the “ESC
Activation/Malfunction Indicator Light” be-
gins to flash during acceleration, ease up on
the accelerator and apply as little throttle as
possible. Be sure to adapt your speed and
driving to the prevailing road conditions.
WARNING!
•Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase
the traction afforded by prevailing road con-
ditions. ESC cannot prevent accidents, in-
cluding those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also cannot
prevent accidents resulting from loss of
WARNING!
vehicle control due to inappropriate driver
input for the conditions. Only a safe, atten-
tive, and skillful driver can prevent acci-
dents. The capabilities of an ESC equipped
vehicle must never be exploited in a reck-
less or dangerous manner which could jeop-
ardize the user’s safety or the safety of
others.
• Vehicle modifications, or failure to prop-
erly maintain your vehicle, may change
the handling characteristics of your ve-
hicle, and may negatively affect the per-
formance of the ESC system. Changes to
the steering system, suspension, brak-
ing system, tire type and size or wheel
size may adversely affect ESC perfor-
mance. Improperly inflated and un-
evenly worn tires may also degrade ESC
performance. Any vehicle modification
or poor vehicle maintenance that re-
duces the effectiveness of the ESC sys-
tem can increase the risk of loss of
vehicle control, vehicle rollover, per-
sonal injury and death.

performance is no longer present, the system
will return to its full performance state. If the
problem persists, see your authorized dealer.
Service FCW Warning
If the system turns off, and the instrument
cluster display reads:
• FCW Unavailable Service Required
This indicates there is an internal system
fault. Although the vehicle is still drivable
under normal conditions, have the system
checked by an authorized dealer.
Tire Pressure Monitor System (TPMS)
The Tire Pressure Monitor System (TPMS)
will warn the driver of a low tire pressure
based on the vehicle recommended cold
placard pressure.
The tire pressure will vary with temperature
by approximately 1 psi (7 kPa) for every 12°F
(6.5°C). This means that when the outside
temperature decreases, the tire pressure willdecrease. Tire pressure should always be set
based on cold inflation tire pressure. This is
defined as the tire pressure after the vehicle
has not been driven for at least three hours, or
driven less than 1 mile (1.6 km) after a three
hour period. The cold tire inflation pressure
must not exceed the maximum inflation pres-
sure molded into the tire sidewall. Refer to
“Tires” in “Servicing And Maintenance” for
information on how to properly inflate the
vehicle’s tires. The tire pressure will also
increase as the vehicle is driven. This is
normal and there should be no adjustment for
this increased pressure.
The TPMS will warn the driver of a low tire
pressure if the tire pressure falls below the
low-pressure warning limit for any reason,
including low temperature effects and natu-
ral pressure loss through the tire. The TPMS
will continue to warn the driver of low tire
pressure as long as the condition exists, and
will not turn off until the tire pressure is at or
above the recommended cold placard pres-
sure.NOTE:
Once the low tire pressure warning (Tire Pres-
sure Monitoring Telltale Light) illuminates,
you must increase the tire pressure to the
recommended cold placard pressure in order
for the “Tire Pressure Monitoring Telltale
Light” to turn off.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(30 kPa) above the recommended cold plac-
ard pressure in order to turn the Tire Pressure
Monitoring Telltale Light off.
The system will automatically update and the
“Tire Pressure Monitoring Telltale Light” will
turn off once the system receives the updated
tire pressures. The vehicle may need to be
driven for up to 10 minutes above 15 mph
(24 km/h) in order for the TPMS to receive
this information.
91

For example, your vehicle may have a recom-
mended cold (parked for more than three
hours) placard pressure of 33 psi (227 kPa).
If the ambient temperature is 68°F (20°C)
and the measured tire pressure is 28 psi
(193 kPa), a temperature drop to 20°F (-7°C)
will decrease the tire pressure to approxi-
mately 24 psi (165 kPa). This tire pressure is
low enough to turn on the “Tire Pressure
Monitoring Telltale Light.” Driving the ve-
hicle may cause the tire pressure to rise to
approximately 28 psi (193 kPa), but the “Tire
Pressure Monitoring Telltale Light” will still
be on. In this situation, the “Tire Pressure
Monitoring Telltale Light” will turn off only
after the tires are inflated to the vehicle’s
recommended cold placard pressure value.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(30 kPa) above the recommended cold plac-
ard pressure in order to turn the Tire Pressure
Monitoring Telltale Light off.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 opera-
tion or sensor damage may result when
using replacement equipment that is not
of the same size, type, and/or style. The
TPM sensor is not designed for use on
aftermarket wheels and may contribute
to a poor overall system performance or
sensor damage. Customers are encour-
aged to use OEM wheels to assure
proper TPM feature operation.
• Using aftermarket tire sealants may
cause the Tire Pressure Monitoring Sys-
tem (TPMS) sensor to become inoper-
able. After using an aftermarket tire
sealant it is recommended that you take
your vehicle to your 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
CAUTION!
from entering the valve stem, which
could damage the TPMS sensor.
NOTE:
• The TPMS is not intended to replace nor-
mal tire care and maintenance, or to pro-
vide 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 efficiency 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 respon-
sibility to maintain correct tire pressure
using an accurate tire pressure gauge, even
if underinflation has not reached the level
to trigger illumination of the “Tire Pressure
Monitoring Telltale Light”.

Air Bag Warning Light
The ORC monitors the readiness of the
electronic parts of the air bag system when-
ever the ignition switch is in the START or
ON/RUN position. If the ignition switch is in
the OFF position or in the ACC position, the
air bag system is not on and the air bags will
not inflate.
The ORC contains a backup power supply
system that may deploy the air bag system
even if the battery loses power or it becomes
disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light
in the instrument panel for approximately
four to eight seconds for a self-check when
the ignition switch is first in the ON/RUN
position. After the self-check, the Air Bag
Warning Light will turn off. If the ORC detectsa malfunction in any part of the system, it
turns on the Air Bag Warning Light, either
momentarily or continuously. A single chime
will sound to alert you if the light comes on
again after initial startup.
The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag
Warning Light if a malfunction is detected
that could affect the air bag system. The
diagnostics also record the nature of the
malfunction. While the air bag system is
designed to be maintenance free, if any of
the following occurs, have an authorized
dealer service the air bag system immedi-
ately.
• The Air Bag Warning Light does not come
on during the four to eight seconds when
the ignition switch is first in the ON/RUN
position.
• The Air Bag Warning Light remains on after
the four to eight-second interval.
• The Air Bag Warning Light comes on inter-
mittently or remains on while driving.NOTE:
If the speedometer, tachometer, or any en-
gine related gauges are not working, the Oc-
cupant Restraint Controller (ORC) may also
be disabled. In this condition the air bags
may not be ready to inflate for your protec-
tion. Have an authorized dealer service the
air bag system immediately.WARNING!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t
have the air bag system to protect you in a
collision. If the light does not come on as a
bulb check when the ignition is first
turned on, stays on after you start the
vehicle, or if it comes on as you drive, have
an authorized dealer service the air bag
system immediately.
Redundant Air Bag Warning Light
If a fault with the Air Bag Warning Light is
detected, which could affect the Supplemen-
tal Restraint System (SRS), the Redundant
Air Bag Warning Light will illuminate on the

Perform the maintenance listed in the
“Scheduled Servicing”. Refer to “Scheduled
Servicing” in “Servicing And Maintenance”
for the proper maintenance intervals. When
towing a trailer, never exceed the GAWR or
GCWR ratings.
WARNING!
Improper towing can lead to a collision.
Follow these guidelines to make your
trailer towing as safe as possible:
• Make certain that the load is secured in
the trailer and will not shift during
travel. When trailering cargo that is not
fully secured, dynamic load shifts can
occur that may be difficult for the driver
to control. You could lose control of your
vehicle and have a collision.
WARNING!
• When hauling cargo or towing a trailer,
do not overload your vehicle or trailer.
Overloading can cause a loss of control,
poor performance or damage to brakes,
axle, engine, transmission, steering,
suspension, chassis structure or tires.
• Safety chains must always be used be-
tween your vehicle and trailer. Always
connect the chains to the hook retainers
of the vehicle hitch. Cross the chains
under the trailer tongue and allow
enough slack for turning corners.
• 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
WARNING!
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 ex-
ceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer
hitch utilized.

WARNING!
Raising the vehicle higher than necessary
can make the vehicle less stable. It could
slip off the jack and hurt someone near it.
Raise the vehicle only enough to remove
the tire.
6. Remove the wheel bolts and tire.
7. Remove the alignment pin from the jack
assembly and thread the pin into the
wheel hub to assist in mounting the spare
tire.
8. Mount the spare tire.
CAUTION!
Be sure to mount the spare tire with the
valve stem facing outward. The vehicle
could be damaged if the spare tire is
mounted incorrectly.NOTE:
• For vehicles equipped, do not attempt
to install a center cap or wheel cover on
the compact spare.
• Refer to “Compact Spare Tire” and to
“Limited-Use Spare” under “Tires—
General Information” in “Servicing And
Maintenance” in the Owner's Manual
for additional warnings, cautions, and
information about the spare tire, its
use, and operation.
9. Install and lightly tighten the wheel bolts.
WARNING!
To avoid the risk of forcing the vehicle off
the jack, do not tighten the wheel nuts
fully until the vehicle has been lowered.
Failure to follow this warning may result in
serious injury.
10. Lower the vehicle to the ground by turn-
ing the jack handle counterclockwise.
11. Finish tightening the wheel bolts. Push
down on the wrench while at the end ofthe handle for increased leverage.
Tighten the wheel bolts in a star pattern
until each wheel bolt has been tightened
twice. Refer to “Wheel And Tire Torque
Specifications” in “Technical Specifica-
tions” for the proper lug bolt torque. If in
doubt about the correct tightness, have
them checked with a torque wrench by
your authorized dealer or at a service
station.
12. Place the jack on the foam tray and open
it far enough so that it is secured. Once
placed in position, rotate it clockwise to
lock it in. Replace the alignment pin in
the center hole to lock the jack in place.
WARNING!
A loose tire or jack thrown forward in a
collision or hard stop could endanger the
occupants of the vehicle. Always stow the
jack parts and the spare tire in the places
provided. Have the deflated (flat) tire re-
paired or replaced immediately.

NOTE:
This declaration becomes invalid, if technical
or operational modifications are introduced
without the manufacture’s consent. Follow
operational manual and instructions for use.Jack Usage Precautions
To complete the Use and Maintenance Hand-
book to which this supplement is attached,
given below are some instructions on the
proper use of the jack.
WARNING!
When using the crank, make sure it turns
freely without the risk of scraping hands
against the ground.
Even the moving parts of the jack, the
“worm screw” and joints can cause inju-
ries: avoid contact with them. Clean it
thoroughly if dirtied with grease.
CAUTION!
The jack is a tool designed exclusively for
changing a wheel, in case of a puncture or
damage to a tire of the vehicle on which it
is fitted or on vehicles of the same model.
Any other use, e.g. to jack up other vehicle
models or different things, is strictly pro-
hibited. Never use it to carry out mainte-
nance or repairs under the vehicle or to
CAUTION!
change summer/winter wheels and vice
versa. Never go under the raised vehicle. If
any work under the vehicle is necessary,
contact the Fiat Service Network. Incor-
rect placing of the jack can cause the
vehicle to drop: use it only in the positions
indicated. Do not use the jack for loads
higher than that specified on the label.
Never start the engine with vehicle raised.
If the vehicle is raised more than neces-
sary, everything can become more un-
stable, with the risk of the vehicle drop-
ping violently. Therefore raise the vehicle
only as much as necessary for the wheel/
spare.
Maintenance
• Make sure grime does not build up on the
“worm screw.”
• Keep the “worm screw” lubricated.
• Never modify the jack.
