2009 JEEP COMPASS brake light

Electronic Stability Program (ESP)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESP 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. ESP 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,
ESP 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.
ESP/TCS Indicator Light
The “ESP/TCS Indicator Light” located in the instrument
cluster, starts to flash as soon as the tires lose traction and
the ESP system becomes active. The “ESP/TCS Indicator
Light” also flashes when TCS is active. If the “ESP/TCS
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!
•Electronic Stability Program (ESP) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions.

CAUTION!
If the trailer weighs more than 1,000 lbs (454 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
WARNING!
Do not connect trailer brakes to your vehicle’s hy-
draulic brake lines. It can overload your brake sys-
tem and cause it to fail. You might not have brakes
when you need them and could have an accident.
Towing any trailer will increase your stopping dis-
tance. When towing you should allow for additional
space between your vehicle and the vehicle in front
of you. Failure to do so could result in an accident.
Towing Requirements — Trailer Lights and Wiring
Whenever you pull a trailer, regardless of the trailer size,
stop lights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a 4- and 7-pin
wiring harness. Use a factory approved trailer harness
and connector.
NOTE:Do not cut or splice wiring into the vehicles
wiring harness.
The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector.
Refer to the following illustrations.

transaxle (CVT2) to go into “default mode” and turn on
the Malfunction Indicator Light (MIL). See your autho-
rized dealer to correct this condition.
1. When boosting from a battery in another vehicle, park
that vehicle within booster cable reach but without
letting the vehicles touch. Set the parking brake, place the
automatic transmission in PARK (the manual transmis-
sion in NEUTRAL) and turn the ignition to OFF for both
vehicles.
2. Turn off the heater, radio and all unnecessary electrical
loads.
3. Using the two finger screws on the cover, remove the
air intake duct covering the battery.
4. Connect one end of a jumper cable to the positive
terminal of the booster battery. Connect the other end of
the jumper cable to the positive terminal of the dis-
charged battery.WARNING!
•Battery fluid is a corrosive acid solution; do not
allow battery fluid to contact eyes, skin or cloth-
ing. Don’t lean over the battery when attaching the
clamps or allow the clamps to touch each other. If
acid splashes in your eyes or on your skin, flush
the contaminated area immediately with large
quantities of water.
•A battery generates hydrogen gas which is flam-
mable and explosive. Keep flame or spark away
from the vent holes. Do not use a booster battery
or any other booster source with an output that
exceeds 12-Volts.
5. Connect the other cable, first to the negative terminal
of the booster battery and then to the negative terminal of
the discharged battery. Make sure you have a good
contact.

ONLY the correct type thermostat. Other designs may
result in unsatisfactory engine coolant (antifreeze)
performance, poor gas mileage, and increased
emissions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Refer to the “Maintenance Schedule” in Section 8 for
proper maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You would not have your full
braking capacity in an emergency.
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 amanual
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. Themanual
transaxleclutch release system should not require fluid
replacement during the life of the vehicle. If the brake

FUSES
Integrated Power Module (IPM)
The Integrated Power Module (IPM) is located in the
engine compartment near the air cleaner assembly. This
center contains cartridge fuses and mini-fuses. A label
that identifies each component may be printed on the
inside of the cover. Refer to “Engine Compartment” in
this section of the Owner’s Manual for the underhood
location of the IPM.
