2018 JEEP COMPASS TRAILHAWK light

WARNING!(Continued)
•The capabilities of an ABS equipped vehicle must
never be exploited in a reckless or dangerous manner
that could jeopardize the user ’s safety or the safety of
others.
ABS is designed to function with the OEM tires. Modifica-
tion may result in degraded ABS performance.
Anti-Lock Brake Warning Light
The yellow “Anti-Lock Brake Warning Light” will turn on
when the ignition is turned to the ON/RUN mode and
may stay on for as long as four seconds.
If the “Anti-Lock Brake Warning Light” remains on or
comes on while driving, it indicates that the anti-lock
portion of the brake system is not functioning and that
service is required. However, the conventional brake sys-
tem will continue to operate normally if the “Anti-Lock
Brake Warning Light” is on.
If the “Anti-Lock Brake Warning Light” is on, the brake
system should be serviced as soon as possible to restore the
benefits of anti-lock brakes. If the “Anti-Lock Brake Warning
Light” does not come on when the ignition is turned to the
ON/RUN mode, have the light repaired as soon as possible.
Electronic Brake Control System
Your vehicle is equipped with an advanced Electronic
Brake Control system (EBC). This system includes Elec-
tronic Brake Force Distribution (EBD), Anti-Lock Brake
System (ABS), Brake Assist System (BAS), Hill Start Assist
(HSA), Traction Control System (TCS), Electronic Stability
Control (ESC), and Electronic Roll Mitigation (ERM). These
systems work together to enhance both vehicle stability
and control in various driving conditions.
Your vehicle may also be equipped with Ready Alert
Braking (RAB), Rain Brake Support (RBS), Trailer Sway
Control (TSC), Hill Descent Control (HDC), and Dynamic
Steering Torque (DST).
Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, the TCS may
apply brake pressure to the spinning wheel(s) and/or
reduce vehicle power to provide enhanced acceleration
and stability. A feature of the TCS, Brake Limited Differen-
tial (BLD), functions similar to a limited slip differential
and controls the wheel spin across a driven axle. If one
wheel on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This

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 apply-
ing the brake of the appropriate wheel(s) to assist in
counteracting the oversteer or understeer condition. En-
gine 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” begins 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.

Partial Off
The “Partial Off” mode is intended for times when a more
spirited driving experience is desired. This mode may
modify TCS and ESC thresholds for activation, which
allows for more wheel spin than normally allowed. This
mode may be useful if the vehicle becomes stuck.
To enter the “Partial Off” mode, momentarily push the
“ESC Off” switch and the “ESC Off Indicator Light” will
illuminate. To turn the ESC on again, momentarily push
the “ESC Off” switch 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
mode “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.

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). TheESC OFF Indicator Light will
always be illuminated when ESC is off.
To turn ESC on again, momentarily push the “ESC Off”
switch. This will restore the “ESC On” mode of operation.
NOTE: The “ESC OFF” message will display and an
audible chime will sound when the gear selector is placed
into the PARK position from any other position, and then
moved out of the PARK position. This will occur even if the
message was previously cleared.

SAFETY 145

WARNING!
There may be situations where the Hill Start Assist
(HSA) will not activate and slight rolling may occur,
such as on minor hills or with a loaded vehicle, or
while pulling a trailer. HSA is not a substitute for
active driving involvement. It is always the driver ’s
responsibility to be attentive to distance to other ve-
hicles, people, and objects, and most importantly brake
operation to ensure safe operation of the vehicle under
all road conditions. Your complete attention is always
required while driving to maintain safe control of your
vehicle. Failure to follow these warnings can result in
a collision or serious personal injury.
Towing With HSA
HSA will also provide assistance to mitigate roll back while
towing a trailer.

Rain Brake Support (RBS)
Rain Brake Support may improve braking performance in
wet conditions. It will periodically apply a small amount of
brake pressure to remove any water buildup on the front
brake rotors. It functions when the windshield wipers are
in LO or HI speed. When Rain Brake Support is active,
there is no notification to the driver and no driver interac-
tion is required.
Ready Alert Braking (RAB)
Ready Alert Braking may reduce the time required to reach
full braking during emergency braking situations. It antici-
pates when an emergency braking situation may occur by
monitoring how fast the throttle is released by the driver.
The EBC will prepare the brake system for a panic stop.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an excessively
swaying trailer and will take the appropriate actions to
attempt to stop the sway. TSC will become active automati-
cally once an excessively swaying trailer is recognized.
NOTE:TSC cannot stop all trailers from swaying. Always
use caution when towing a trailer and follow the trailer
tongue weight recommendations. Refer to “Trailer Tow-
ing” in “Starting And Operating” for further information. When TSC is functioning, the “ESC Activation/
Malfunction Indicator Light” will flash, the engine power
may be reduced and you may feel the brakes being applied
to individual wheels to attempt to stop the trailer from
swaying. TSC is disabled when the ESC system is in the
“Partial Off” or “Full Off” modes.

WARNING!
•If a child restraint system, child, small teenager or
adult in the front passenger seat is seated improp-
erly, the occupant may provide an output signal to
the OCS that is different from the occupant’s prop-
erly seated weight input. This may result in serious
injury or death in a collision.
• Always wear your seat belt and sit properly, with the
seatback in an upright position, your back against
the seatback, sitting upright, facing forward, in the
center of the seat, with your feet comfortably on or
near the floor.
• Do not carry or hold any objects (e.g., backpacks,
boxes, etc.) while seated in the front passenger seat.
Holding an object may provide an output signal to
the OCS that is different than the occupant’s prop-
erly seated weight input, which may result in serious
injury or death in a collision.
• Placing an object on the floor under the front pas-
senger seat may prevent the OCS from working
properly, which may result in serious injury or death
in a collision. Do not place any objects on the floor
under the front passenger seat. The Air Bag Warning Light

WARNING!
•Side Air Bags need room to inflate. Do not lean
against the door or window. Sit upright in the center
of the seat.
• Being too close to the Side Air Bags during deploy-
ment could cause you to be severely injured or
killed.
• Relying on the Side Air Bags alone could lead to
more severe injuries in a collision. The Side Air Bags
work with your seat belt to restrain you properly. In
some collisions, Side Air Bags won’t deploy at all.
Always wear your seat belt even though you have
Side Air Bags.
NOTE: Air bag covers may not be obvious in the interior
trim, but they will open during air bag deployment.
Rollover Events
Side Air Bags are designed to activate in certain rollover
events. The ORC determines whether the deployment of
the Side Air Bags in a particular rollover event is appro-
priate, based on the severity and type of collision. Vehicle
damage by itself is not a good indicator of whether or not
Side Air Bags should have deployed. The Side Air Bags will not deploy in all rollover events. The
rollover sensing system determines if a rollover event may
be in progress and whether deployment is appropriate. In
the event the vehicle experiences a rollover or near rollover
event, and deployment of the Side Air Bags is appropriate,
the rollover sensing system will also deploy the seat belt
pretensioners on both sides of the vehicle.
The SABICs may help reduce the risk of partial or complete
ejection of vehicle occupants through side windows in
certain rollover or side impact events.
