2010 JEEP COMPASS brake light

required. However, the conventional brake system will
continue to operate normally if the “Brake Warning
Light” is not on.
If the “ABS Warning Light” is on, the brake system
should be serviced as soon as possible to restore the
benefits of anti-lock brakes. If the “ABS Warning Light”
does not come on when the ignition switch is turned to
the ON position, have the bulb repaired as soon as
possible.
If both the “Brake Warning Light” and the “ABS Warning
Light” remain on, the ABS and Electronic Brake Force
Distribution (EBD) systems are not functioning. Immedi-
ate repair to the ABS is required.
When the vehicle is driven over 7 mph (11 km/h), you
may also hear a slight clicking sound as well as some
related motor noises. These noises are the system per-
forming its self-check cycle to ensure that the ABSworking 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.
298 STARTING AND OPERATING

Hill Start Assist (HSA) – Manual Transaxle Only
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.
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% 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 (i.e., less than
8%), 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 braking 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.
302 STARTING AND OPERATING

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 transaxle into NEUTRAL.
3. Apply the parking brake.
4. Start the engine.
5. Release the clutch pedal.
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 Off 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 completed
properly, the “ESC Off Indicator 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
5
STARTING AND OPERATING 303

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.
ESC Off Indicator Light
The “ESC Off Indicator Light” (located in the
instrument cluster) starts to flash as soon as the
tires lose traction and the ESC system becomes
active. The “ESC Off Indicator Light” also
flashes when TCS is active. If the “ESC Off 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.
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
resulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning. Only a
safe, attentive, and skillful driver can prevent
accidents.
•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.
304 STARTING AND OPERATING

Brake Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately if
the brake system warning light is on.
Be sure to clean the top of the master cylinder area before
removing the cap. If necessary, add fluid to bring the
fluid level up to the requirements described on the brake
fluid reservoir. Fluid level can be expected to fall as the
brake pads wear. The brake fluid level should be checked
when the pads are replaced. However, low fluid level
may be caused by a leak and a checkup may be needed.
NOTE:If your vehicle is equipped with a manual
transaxle , the brake fluid reservoir supplies fluid to both
the brake system and the clutch release system. The two
systems are separated in the reservoir, and a leak in one
system will not affect the other system. The manual
transaxle clutch release system should not require fluid
replacement during the life of the vehicle. If the brake fluid reservoir is low and the brake system does not
indicate any leaks or other problems, it may be a result of
a leak in the hydraulic clutch release system. See your
local authorized dealer for service.
Use only manufacturer’s recommended brake fluid. Re-
fer to “Fluids, Lubricants, and Genuine Parts” in “Main-
taining Your Vehicle” for further information.
WARNING!
•Use only manufacturer’s recommended brake fluid.
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further informa-
tion. Using the wrong type of brake fluid can
severely damage your brake system and/or impair
its performance. The proper type of brake fluid for
your vehicle is also labeled on the original factory
installed hydraulic master cylinder reservoir.
