2007 JEEP COMPASS light

Where one or more wheels have wheel spin or if addi-
tional traction is needed in sand, deep snow, or loose
traction surfaces, activate the 4WD Lock switch by pull-
ing up once and releasing. This locks the center coupling
allowing more torque to be sent to the rear wheels. The
amber4WDlight will come on in the cluster. This can be
done on the fly, at any vehicle speed. To deactivate,
simply pull on the switch one more time. The cluster light
will then go out.
NOTE:Refer to ”ESP (Electronic Stability Program) in
the “Electronic Brake Control System” section of this
manual for additional information.PARKING BRAKE
When the parking brake is applied with the
ignition on, the Brake Light in the instrument
cluster will come on.
NOTE:This light only shows that the parking brake is
on. It does not show the degree of brake application.
If the parking brake is applied while the vehicle is
moving, a chime will sound to alert the driver. The chime
will sound up to 10 times or until the vehicle has
returned to a stop.
Before leaving the vehicle, make sure that the parking
brake is set. To set the parking brake, pull up firmly on
the lever. Also place the gear selector in the Park position
(automatic transaxle) or Reverse (manual transaxle). To
release the parking brake, apply the brake pedal, pull up
244 STARTING AND OPERATING

slightly on the lever, then depress the button on the end
of the lever and push the lever fully down toward the
floor.
NOTE:The parking brake lever will not release unless
the lever is pulled up slightly past its applied position.When parking on a hill, it is important to set the parking
brake before placing the gear selector in Park, otherwise
the load on the automatic transaxle locking mechanism
may make it difficult to move the selector out of Park. As
an added precaution, turn the front wheels toward the
curb on a downhill grade and away from the curb on a
uphill grade.
You should always apply the parking brake before leav-
ing the vehicle.

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
indicator will light.
WARNING!
Driving a vehicle with the brake light on is danger-
ous. A significant decrease in braking performance
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 an acci-
dent. Have the vehicle checked immediately.
Anti-Lock Brake System (ABS) — If Equipped
The Anti-Lock Brake System 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 an accident.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need to
slow down or stop.

WARNING!
•Anti-lock system (ABS) cannot prevent the natu-
ral laws of physics from acting on the vehicle, nor
can it increase braking or steering efficiency be-
yond that afforded by the condition of the vehicle
brakes and tires or the traction afforded.
•The ABS cannot prevent accidents, including
those resulting from excessive speed in turns,
following another vehicle too closely, or hydro-
planing. Only a safe, attentive, and skillful driver
can prevent accidents.
•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.
The ABS light monitors the Anti-Lock Brake
System. The light will come on when the
ignition switch is turned to the ON position
and may stay on for as long as four seconds.
If the ABS 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 system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS 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 Light
remain on, the Anti-Lock brakes (ABS) and Electronic
Brake Force Distribution (EBD) systems are not function-
ing. Immediate repair to the ABS system is required.
248 STARTING AND OPERATING

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 ABS system
is 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 also may experience the following when the brake
system goes into Anti-lock:
•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,
•and 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 contains sophisticated
electronic equipment that may be susceptible to
interference caused by improperly installed or high
output radio transmitting equipment. This interfer-
ence can cause possible loss of anti-lock braking
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.

TIRE SAFETY INFORMATION
Tire Markings
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 designation. Ex-
ample: 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-Metric
tires 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.
