JEEP COMPASS 2015 1.G Owners Manual

WARNING!
The Anti-Lock Brake System (ABS) contains sophis-
ticated electronic equipment that may be susceptible
to interference caused by improperly installed or
high output radio transmitting equipment. This in-
terference can cause possible loss of Anti-Lock brak-
ing capability. Installation of such equipment should
be performed by qualified professionals.
All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS system 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 will allow more engine
torque to be applied to the wheel that is not spinning.
This feature remains active even if TCS and ESC are in
either the “Partial Off” or “Full Off” modes. Refer to
“Electronic Stability Control (ESC)” in this section of this
manual.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing the rate and amount of brake application and then
applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
Anti-Lock Brake System (ABS). Applying the brakes very
quickly results in the best BAS assistance. To receive the
5
STARTING AND OPERATING 359

benefit of the system, you must applycontinuousbrak-
ing pressure during the stopping sequence (do not
“pump” the brakes). Do not reduce brake pedal pressure
unless braking is no longer desired. Once the brake pedal
is released, the BAS is deactivated.
WARNING!
•The Brake Assist System (BAS) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevail-
ing road conditions.
•The BAS cannot prevent collisions, including those
resulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning.
•The capabilities of a BAS-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 Roll Mitigation (ERM)
This system anticipates the potential for wheel lift by
monitoring the driver ’s steering wheel input and the
speed of the vehicle. When ERM determines that the rate
of change of the steering wheel angle and vehicles speed
are sufficient to potentially cause wheel lift, it applies the
brake of the appropriate wheel and may also reduce
engine power to lessen the chance that wheel lift will
occur. ERM will only intervene during very severe or
evasive driving maneuvers.
ERM can only reduce the chance of wheel lift occurring
during severe or evasive driving maneuvers. It can not
prevent wheel lift due to other factors such as road
conditions, leaving the roadway or striking objects or
other vehicles.
360 STARTING AND OPERATING

NOTE:Anytime the ESC system is in the “Full Off”
mode, ERM is disabled. Refer to “Electronic Stability
Control (ESC)” in this section for a complete explanation
of the available ESC modes.
WARNING!
Many factors, such as vehicle loading, road condi-
tions and driving conditions, influence the chance
that wheel lift or rollover may occur. ERM cannot
prevent all wheel lift or roll overs, especially those
that involve leaving the roadway or striking objects
or other vehicles. The capabilities of an ERM-
equipped vehicle must never be exploited in a reck-
less or dangerous manner which could jeopardize the
user’s safety or the safety of others.
Hill Descent Control (HDC) — If Equipped
This system maintains vehicle speed while descending
hills during off-road driving situations. HDC will auto-
matically apply the brakes to control downhill speed to
between 4 mph (7 km/h) and 6 mph (9 km/h) depending
on terrain. The system is activated by placing the vehicle
in “Off-Road” mode and placing the shift lever in LOW
or REVERSE. Refer to “Safe Off-Road Driving” in “Start-
ing and Operating” for further information.
When HDC is properly enabled, the “Hill
Decent Control Light” in the instrument cluster
will be illuminated.
HDC has the capability to sense terrain and will only
activate when the vehicle is descending a hill. It will not
activate on level ground. If desired, HDC can be fully
deactivated by putting the vehicle into ESC “Full Off”
5
STARTING AND OPERATING 361

mode. This is done by pressing and holding the “ESC
Off” button for five seconds. Refer to “Electronic Stability
Control (ESC)” in this section of the manual.
HDC operation can be overridden with brake application
to slow the vehicle down below the HDC control speed.
Conversely, if more speed is desired during HDC control,
the accelerator pedal will increase vehicle speed like
normal. When either the brake or the accelerator is
released, HDC will control the vehicle back to the origi-
nal set speed.
HDC is only intended for low speed off-road driving. At
vehicle speeds above 31 mph (50 km/h) HDC will no
longer function. If the “HDC Indicator Light” begins to
flash this indicates that the brakes are getting too hot and
the vehicle should be stopped to allow the brakes to cool.
WARNING!
HDC is only intended to assist the driver in control-
ling vehicle speed when descending hills. The driver
must remain attentive to the driving conditions and
is responsible for maintaining a safe vehicle speed.
Hill Start Assist (HSA)
The HSA system is designed to assist the driver when
starting a vehicle from a stop on a hill. HSA will maintain
the level of brake pressure the driver applied for a short
period of time after the driver takes their foot off of the
brake pedal. If the driver does not apply the throttle
during this short period of time, the system will release
brake pressure and the vehicle will roll down the hill. The
system will release brake pressure in proportion to
amount of throttle applied as the vehicle starts to move in
the intended direction of travel.
362 STARTING AND OPERATING

HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
•Vehicle must be stopped.
•Vehicle must be on a 7% (approximate) grade or greater
hill.
•Gear selection matches vehicle uphill direction (i.e.,
vehicle facing uphill is in forward gear; vehicle back-
ing uphill is in REVERSE gear).
WARNING!
There may be situations on minor hills with a loaded
vehicle, or while pulling a trailer, when the system
will not activate and slight rolling may occur. This
could cause a collision with another vehicle or object.
Always remember the driver is responsible for brak-
ing the vehicle.
Disabling/Enabling HSA
If you wish to turn on or off the HSA system, it can be
done using the Customer Programmable Features in the
Electronic Vehicle Information Center (EVIC). Refer to
“Electronic Vehicle Information Center (EVIC)” in “Un-
derstanding Your Instrument Panel” for further informa-
tion.
For vehicles not equipped with the EVIC, perform the
following steps:
NOTE:You must complete Steps 1 through 8 within 90
seconds.
1. Center the steering wheel (front wheels pointing
straight forward).
2. Shift the transmission into NEUTRAL.
3. Apply the parking brake.
4. Start the engine.
5
STARTING AND OPERATING 363

5. Release the clutch pedal (if equipped).
6. Rotate the steering wheel one-half turn to the left.
7. Press the “ESC Off” switch (located in the lower
switch bank below the climate controls) four times
within 20 seconds. The “ESC Activation/Malfunction
Indicator Light” should turn on and turn off two
times.
8. Rotate the steering wheel back to center and then an
additional half-turn to the right.
9. Turn the ignition switch to the OFF position and then
back to the ON position. If the sequence was com-
pleted properly, the “ESC Activation/Malfunction In-
dicator Light” will blink several times to confirm HSA
is disabled.
10. Repeat these steps if you want to return this feature
to it’s previous setting.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects for over-steering or under-steering of the vehicle by
applying the brake of the appropriate wheel to assist in
counteracting the over-steering or under-steering condi-
tion. 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 over-steer or under-steer condition
•Over-steer - when the vehicle is turning more than
appropriate for the steering wheel position.
•Under-steer - when the vehicle is turning less than
appropriate for the steering wheel position.
364 STARTING AND OPERATING

WARNING!
•The Electronic Stability Control (ESC) cannot pre-
vent the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions.
•ESC cannot prevent accidents, including those re-
sulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning. ESC also
cannot prevent collisions resulting from loss of
vehicle control due to inappropriate driver input
for the conditions. Only a safe, attentive, and
skillful driver can prevent collisions.
•The capabilities of an ESC-equipped vehicle must
never be exploited in a reckless or dangerous
manner, which could jeopardize the user’s safety or
the safety of others.
ESC Operating Modes
The ESC system has three available operating modes for
four–wheel drive equipped vehicles and two available
operating modes for two–wheel drive equipped vehicles.
Full On (Four-Wheel Drive Models) Or On
(Two-Wheel Drive Models)
This is the normal operating mode for ESC. Whenever
the vehicle is started the ESC system will be in this “On”
mode. This mode should be used for most driving
situations. ESC should only be turned to “Partial Off” or
“ESC Off” for specific reasons as noted below.
Partial Off (Four-Wheel Drive Models) Or On
(Two-Wheel Drive Models)
This mode is entered by momentarily pressing the “ESC
Off” switch. When in “Partial Off” mode, the TCS portion
of ESC, except for the “limited slip” feature described in
5
STARTING AND OPERATING 365

the TCS section, has been disabled and the#ESC OFF
Indicator Light#will be illuminated. All other stability
features of ESC function normally. This mode is intended
to be used if the vehicle is in deep snow, sand or gravel
conditions and more wheel spin than ESC would nor-
mally allow is required to gain traction.
To turn ESC on again, momentarily press the “ESC Off”
switch. This will restore the normal “ESC On” mode of
operation.
NOTE:To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand or
gravel, it may be desirable to switch to the “Partial Off”
mode by pressing the “ESC Off” switch. Once the situa-
tion requiring ESC to be switched to the “Partial Off”
mode is overcome, turn ESC back on by momentarily
pressing the “ESC Off” switch. This may be done while
the vehicle is in motion.
WARNING!
When in “Partial Off” mode, the TCS functionality 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 “Par-
tial Off” mode, the engine power reduction of TCS is
disabled, and the enhanced vehicle stability offered
by the ESC system is reduced. Trailer Sway control
(TSC) (if equipped) is disabled when the ESC system
is in the%Partial Off%mode.
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 maneu-
verability due to trail conditions. This mode is entered
by pressing and holding the “ESC Off” switch for five
366 STARTING AND OPERATING

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 odometer. Press and release the Trip
Odometer button located on the instrument cluster to
clear this message.
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 35 mph (56 km/h). At
35 mph (56 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 35 mph (56 km/h). The#ESC OFF Indicator
Light#will always be illuminated when ESC is off.
To turn ESC on again, momentarily press 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 shift lever 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.
WARNING!
With the ESC in the%Full Off%mode, the engine
torque reduction and stability features are disabled.
In an emergency evasive maneuver, the ESC system
will not engage to assist in maintaining stability.
“ESC Off” mode is intended for off-highway or
off-road use only.

STARTING AND OPERATING 367

ESC Activation/Malfunction Indicator Light And
ESC OFF Indicator Light
The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is cycled to the ON/
RUN position. It should go out with the engine
running. If the “ESC Activation/Malfunction Indicator
Light” comes on continuously with the engine running, a
malfunction has been detected in the ESC system. If this
light remains on after several ignition cycles, and the
vehicle has been driven several miles (kilometers) at
speeds greater than 30 mph (48 km/h), see your autho-
rized dealer as soon as possible to have the problem
diagnosed and corrected.
The “ESC Activation/Malfunction Indicator Light” (lo-
cated in the instrument cluster) starts to flash as soon as
the tires lose traction and the ESC system becomes active.
The “ESC Activation/Malfunction Indicator Light” also
flashes when TCS is active. If the “ESC Activation/
Malfunction Indicator Light” begins to flash during ac-
celeration, 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.
NOTE:
•The “ESC Off Indicator Light” and the “ESC Acti-
vation/Malfunction Indicator Light” come on momen-
tarily each time the ignition switch is turned to the
ON/RUN position.
