2019 JEEP COMPASS four wheel drive

Your vehicle may be equipped with the follow-
ing Air Bag System Components:
Air Bag System Components
• Occupant Restraint Controller (ORC)
• Air Bag Warning Light
• Steering Wheel and Column
• Instrument Panel
• Knee Impact Bolsters
• Driver and Front Passenger Air Bags
• Seat Belt Buckle Switch
• Supplemental Side Air Bags
• Front and Side Impact Sensors
• Seat Belt Pretensioners
• Seat Track Position Sensors
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 detects
a 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 immediately.•
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.

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 an authorized
dealer at your earliest possible convenience.
An 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 auto-
matic 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 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.
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.
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).
Enabling Four Wheel Drive (4x4)
The buttons for the activation of four wheel
drive are located on the device Selec-Terrain
and allow you to select the following:
•4WD LOCK
•4WD LOW — (Trailhawk models only)STARTING AND OPERATING
158

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
Rotate the Selec-Terrain knob to select the
desired mode.
•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 maneuverabil-
ity and acceleration improvement com-
pared 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 traction, such as roads covered with
snow. When in SNOW mode (depending on
certain operating conditions), the transmis-
sion may use second gear (rather than first
gear) during launches, to minimize wheel
slippage.
•SAND: For off-road driving or use on sur-
faces with poor traction, such as dry sand.
The transmission is set to provide maxi-
mum traction.
•MUD: For off-road driving or use on surfaces
with poor traction, such as roads covered by
mud or wet grass.
•ROCK(Trailhawk only): This mode is only
available 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.

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.
• 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.
WARNING!
• 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
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.

instructions on shifting the automatic trans-
mission out of PARK so that the vehicle can
be moved.
CAUTION!
• Do not use sling-type equipment when
towing. Vehicle damage may occur.
• When securing the vehicle to a flatbed
truck, do not attach to front or rear
suspension components. Damage to
your vehicle may result from improper
towing.
• Ensure that the Electric Park Brake is
released, and remains released, while
being towed.
• Do not use a bumper mounted clamp-on
tow bar on your vehicle. The bumper
face bar will be damaged.
Without The Key Fob
Special care must be taken when the vehicle
is towed with the ignition in the LOCK/OFF
mode. The only approved method of towing
without the key fob is with a flatbed truck.
Proper towing equipment is necessary to pre-
vent damage to the vehicle.
Front-Wheel Drive (FWD) Models —
With Key Fob
The manufacturer recommends towing your
vehicle with all four wheelsOFFthe ground
using a flatbed.
If flatbed equipment is not available, this
vehicle must be towed with the front wheels
OFFthe ground (using a towing dolly, or wheel
lift equipment with the front wheels raised).
Ensure that the Electric Park Brake is re-
leased, and remains released, while being
towed. The Electric Park Brake does not need
to be released if all four wheels are off the
ground.
CAUTION!
Towing this vehicle in violation of the
above requirements can cause severe en-
gine and/or transmission damage. Damage
from improper towing is not covered under
the New Vehicle Limited Warranty.
4x4 Models
The manufacturer requires towing with all
four wheelsOFFthe ground.
Acceptable methods are to tow the vehicle on
a flatbed, or with one end of the vehicle
raised and the opposite end on a towing dolly.
CAUTION!
• Front or rear wheel lifts must not be used
(if the remaining wheels are on the
ground). Internal damage to the trans-
mission or transfer case will occur if a
front or rear wheel lift is used when
towing.

WARNING!
resulting in serious injury or death. Use
only the tire and wheel sizes with load
ratings approved for your vehicle.
• Never use a tire with a smaller load index
or capacity, other than what was origi-
nally equipped on your vehicle. Using a
tire with a smaller load index could re-
sult in tire overloading and failure. You
could lose control and have a collision.
• Failure to equip your vehicle with tires
having adequate speed capability can
result in sudden tire failure and loss of
vehicle control.
CAUTION!
Replacing original tires with tires of a
different size may result in false speedom-
eter and odometer readings.
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all sea-
sons (Spring, Summer, Fall, and Winter).
Traction levels may vary between different all
season tires. All season tires can be identified
by the M+S, M&S, M/S or MS designation on
the tire sidewall. Use all season tires only in
sets of four; failure to do so may adversely
affect the safety and handling of your vehicle.
Summer Or Three Season Tires —
If Equipped
Summer tires provide traction in both wet
and dry conditions, and are not intended to
be driven in snow or on ice. If your vehicle is
equipped with Summer tires, be aware these
tires are not designed for Winter or cold
driving conditions. Install Winter tires on your
vehicle when ambient temperatures are less
than 40°F (5°C) or if roads are covered with
ice or snow. For more information, contact an
authorized dealer.
Summer tires do not contain the all season
designation or mountain/snowflake symbol
on the tire sidewall. Use Summer tires only insets of four; failure to do so may adversely
affect the safety and handling of your vehicle.
WARNING!
Do not use Summer tires in snow/ice con-
ditions. You could lose vehicle control,
resulting in severe injury or death. Driving
too fast for conditions also creates the
possibility of loss of vehicle control.
Snow Tires
Some areas of the country require the use of
snow tires during the Winter. Snow tires can
be identified by a “mountain/snowflake”
symbol on the tire sidewall.
If you need snow tires,
select tires equivalent
in size and type to the
original equipment
tires. Use snow tires
only in sets of four;
failure to do so may
adversely affect the
safety and handling of
your vehicle.

The suggested Four Wheel Drive (4WD) Tire
rotation method is the “rearward cross”
shown in the following diagram.
CAUTION!
Proper operation of four-wheel drive ve-
hicles depends on tires of equal size, type
and circumference on each wheel. Any
difference in tire size can cause damage to
the power transfer unit. Tire rotation
schedule should be followed to balance
tire wear.
STORING THE VEHICLE
If the vehicle should remain stationary for
more than a month, observe the following
precautions:
• Park your vehicle in a covered, dry and
possibly airy location the windows open
slightly.
• Check that the Electric Park Brake is not
engaged.
• Disconnect the negative (-) terminal from
the battery post and be sure that the battery
is fully charged. During storage check bat-
tery charge quarterly.
• If you do not disconnect the battery from
the electrical system, check the battery
charge every 30 days.
• Clean and protect the painted parts by
applying protective waxes.
• Clean and protect polished metal parts by
applying protective waxes.
• Apply talcum powder to the front and rear
wiper blades and leave raised from the
glass.• Cover the vehicle with an appropriate cover
taking care not to damage the painted sur-
face by dragging across dirty surfaces. Do
not use plastic sheeting which will not allow
the evaporation of moisture present on the
surface of the vehicle.
• Inflate the tires at a pressure of +7.25 psi
(+0.5 bar) higher than recommended on
the tire placard and check it periodically.
• Do not drain the engine cooling system.
• Whenever you leave the vehicle stationary
for two weeks or more, idle the engine for
approximately five minutes, with the air
conditioning system on and high fan speed.
This will ensure proper lubrication of the
system, thus minimizing the possibility of
damage to the compressor when the vehicle
is put back into operation.
NOTE:
When the vehicle has not been started or
driven for at least 30 days, an Extended Park
Start Procedure is required to start the ve-
hicle.
Refer to “Starting The Engine” in “Starting
And Operating” for further information.
