2009 JEEP COMPASS ABS

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
(TCS), Brake Assist System (BAS), Electronic Roll Mitiga-
tion (ERM), and Electronic Stability Program (ESP). All
systems work together to enhance vehicle stability and
control in various driving conditions and are commonly
referred to as ESP.
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 this section of the
manual for more information about ABS.
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 ESP are in
either the “Partial Off” or “Full Off” modes. Refer to
“Electronic Stability Program (ESP)” in this Section of this
manual.
272 STARTING AND OPERATING

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
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 accidents, including
those resulting from excessive speed in turns,
driving on very slippery surfaces, or hydroplan-
ing. Only a safe, attentive, and skillful driver can
prevent accidents.
•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.

NOTE:
•P (Passenger) - Metric tire sizing is based on U.S.
design standards. P-Metric tires have the letter “P”
molded into the sidewall preceding the size designa-
tion. Example: P215/65R15 95H.
•European-Metric tire sizing is based on European
design standards. Tires designed to this standard have
the tire size molded into the sidewall beginning with
the section width. The letterPis absent from this tire
size designation. Example: 215/65R15 96H.
•LT (Light Truck) - Metric tire sizing is based on U.S.
design standards. The size designation for LT-Metrictires is the same as for P-Metric tires except for the
letters “LT” that are molded into the sidewall preced-
ing the size designation. Example: LT235/85R16.
•Temporary spare tires are high-pressure compact
spares designed for temporary emergency use only.
Tires designed to this standard have the letter “T”
molded into the sidewall preceding the size designa-
tion. Example: T145/80D18 103M.
•High flotation tire sizing is based on U.S. design
standards and it begins with the tire diameter molded
into the sidewall. Example: 31x10.5 R15 LT.

EXAMPLE:
Service Description:
95= Load Index
— A numerical code associated with the maximum load a tire can carry
H= Speed Symbol
— A symbol indicating the range of speeds at which a tire can carry a load corresponding to
its load index under certain operating conditions
— The maximum speed corresponding to the speed symbol should only be achieved under
specified operating conditions (i.e., tire pressure, vehicle loading, road conditions, and
posted speed limits)
Load Identification:
....blank....= Absence of any text on the sidewall of the tire indicates a Standard Load (SL) tire
Extra Load (XL)= Extra load (or reinforced) tire
Light Load= Light load tire
C, D, E= Load range associated with the maximum load a tire can carry at a specified pressure
Maximum Load— Maximum load indicates the maximum load this tire is designed to carry
Maximum Pressure—
Maximum pressure indicates the maximum permissible cold tire inflation pressure for this tire

CAUTION!
•When installing the IPM cover, it is important to
ensure the cover is properly positioned and fully
latched. Failure to do so may allow water to get
into the IPM, and possibly result in an electrical
system failure.

Customer Assistance For The Hearing Or Speech
Impaired (TDD/TTY)
To assist customers who have hearing difficulties, the
manufacturer has installed special TDD (Telecommuni-
cation Devices for the Deaf) equipment at its customer
center. Any hearing or speech impaired customer, who
has access to a TDD or a conventional teletypewriter
(TTY) in the United States, can communicate with the
manufacturer by dialing 1–800–380–CHRY.
Service Contract
You may have purchased a service contract for a vehicle
to help protect you from the high cost of unexpected
repairs after the manufacturer’s New Vehicle Limited
Warranty expires. The manufacturer stands behind only
the manufacturer’s service contracts. If you purchased a
manufacturer’s service contract, you will receive Plan
Provisions and an Owner Identification Card in the mail
within three weeks of the vehicle delivery date. If youhave any questions about the service contract, call the
manufacturer’s Service Contract National Customer Hot-
line at 1-800-521-9922.
The manufacturer will not stand behind any service
contract that is not the manufacturer’s service contract. It
is not responsible for any service contract other than the
manufacturer’s service contract. If you purchased a ser-
vice contract that is not a manufacturer’s service contract,
and you require service after the manufacturer’s New
Vehicle Limited Warranty expires, please refer to the
contract documents, and contact the person listed in
those documents.
We appreciate that you have made a major investment when
you purchased the vehicle. An authorized dealer has also
made a major investment in facilities, tools, and training to
assure that you are absolutely delighted with the ownership
experience. You’ll be pleased with their sincere efforts to
resolve any warranty issues or related concerns.
