2014 JEEP COMPASS stop start

and hill descent braking to control the descent and apply
your brakes if necessary, but do not allow the tires to lock.
WARNING!
If the engine stalls or you lose headway or cannot
make it to the top of a steep hill or grade, never
attempt to turn around. To do so may result in
tipping and rolling the vehicle, which may result in
severe injury. Always back carefully straight down a
hill in REVERSE gear. Never back down a hill in
NEUTRAL using only the vehicle brakes. Never
drive diagonally across a hill, always drive straight
up or down.
Driving Through Water
Extreme care should be taken crossing any type of water.
Water crossings should be avoided if possible, and onlybe attempted when necessary in a safe responsible man-
ner. You should only drive through areas which are
designated and approved. You should tread lightly and
avoid damage to the environment. You should know
your vehicles abilities and be able to recover it if some-
thing goes wrong. You should never stop or shut a
vehicle off when crossing deep water unless you ingested
water into the engine air intake. If the engine stalls, do
not attempt to restart it. Determine if it has ingested
water first. The key to any crossing is low and slow. You
want to use low (L Off-Road) with the 4WD LOCK
engaged and proceed very slowly with a constant slow
speed (3-5 mph [5–8 km/h] maximum) and light throttle.
Keep the vehicle moving; do not try to accelerate through
the crossing. After crossing any water higher than the
bottom of the axle differentials, you should inspect all of
the vehicle fluids for signs of water ingestion.
358 STARTING AND OPERATING

If either of the two hydraulic systems lose normal capa-
bility, the remaining system will still function with some
loss of overall braking effectiveness. This will be evident
by increased pedal travel during application and greater
pedal force required to slow or stop. In addition, if the
malfunction is caused by an internal leak, as the brake
fluid in the master cylinder drops, the “Brake Warning
Light” will light.
WARNING!
Driving a vehicle with the “Brake Warning Light” on
is dangerous. A significant decrease in braking per-
formance or vehicle stability during braking may
occur. It will take you longer to stop the vehicle or
will make your vehicle harder to control. You could
have a collision. Have the vehicle checked immedi-
ately.
Anti-Lock Brake System (ABS)
The ABS provides increased vehicle stability and brake
performance under most braking conditions. The system
automatically “pumps” the brakes during severe braking
conditions to prevent wheel lock-up.
WARNING!
•Pumping of the anti-lock brakes will diminish
their effectiveness and may lead to a collision.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need to
slow down or stop.
• The ABS cannot prevent the natural laws of phys-
ics from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that afforded
by the condition of the vehicle brakes and tires or
the traction afforded.

working properly. This self-check occurs each time the
vehicle is started and accelerated past 7 mph (11 km/h).
ABS is activated during braking under certain road or
stopping conditions. ABS-inducing conditions can in-
clude ice, snow, gravel, bumps, railroad tracks, loose
debris, or panic stops.
You may also experience the following when the brake
system goes into anti-lock mode:
•The ABS motor running (it may continue to run for a
short time after the stop).
• The clicking sound of solenoid valves.
• Brake pedal pulsations.
• A slight drop or fall away of the brake pedal at the end
of the stop.
These are all normal characteristics of ABS.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.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle may be equipped with an optional ad-
vanced electronic brake control system that includes
Anti-Lock Brake System (ABS), Traction Control System
368 STARTING AND OPERATING

(TCS), Brake Assist System (BAS), Electronic Roll Mitiga-
tion (ERM), Hill Descent Control (HDC), Hill Start Assist
(HSA), and Electronic Stability Control (ESC). All sys-
tems work together to enhance vehicle stability and
control in various driving conditions and are commonly
referred to as ESC.
Anti-Lock Brake System (ABS)
This system aids the driver in maintaining vehicle control
under adverse braking conditions. The system controls
hydraulic brake pressure to prevent wheel lockup and
help avoid skidding on slippery surfaces during braking.
Refer to “Anti-Lock Brake System” in “Starting and
Operating” for further information.
WARNING!
•Pumping of the anti-lock brakes will diminish
their effectiveness and may lead to a collision.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need to
slow down or stop.
• The ABS cannot prevent the natural laws of phys-
ics from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that afforded
by the condition of the vehicle brakes and tires or
the traction afforded.
• The ABS cannot prevent collisions, including those
resulting from excessive speed in turns, following
another vehicle too closely, or hydroplaning.
• The capabilities of an ABS-equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety or
the safety of others.

STARTING AND OPERATING 369

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. Thesystem 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
benefit of the system, you must apply
continuousbrak-
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.

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 maintainthe 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.
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.5
STARTING AND OPERATING 373

Indicator Lightwill 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
seconds when the vehicle is stopped and the engine is
running. After five seconds, the ESC OFF Indicator

•The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.
The “ESC OFF Indicator Light” indicates the
Electronic Stability Control (ESC) is partially
off or full off.TIRE SAFETY INFORMATION
