brake fluid JEEP GRAND CHEROKEE 2016 WK2 / 4.G SRT Owners Manual

Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid (if
equipped), or brake fluid leaks are suspected. The cause
should be located and corrected immediately.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 113

Brake Warning Light
Red TelltaleLight What It Means
United States
Canada
Brake Warning Light
This light monitors various brake functions, including brake fluid level and parking brake
application. If the brake light turns on it may indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with the anti-lock brake system reser-
voir.
If the light remains on when the parking brake has been disengaged, and the fluid level is at
the full mark on the master cylinder reservoir, it indicates a possible brake hydraulic system
malfunction or that a problem with the Brake Booster has been detected by the Anti-Lock
Brake System (ABS) / Electronic Stability Control (ESC) system. In this case, the light will
remain on until the condition has been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake, and a brake pedal pulsation may
be felt during each stop.
The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.

The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed.
It will take longer to stop the vehicle. You could have
a collision. Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake System
(ABS) are also equipped with Electronic Brake Force Distribution (EBD). In the event of an EBD failure, the
Brake Warning Light will turn on along with the ABS
Light. Immediate repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
placing the ignition in the position ON/RUN position.
The light should illuminate for approximately two sec-
onds. The light should then turn off unless the parking
brake is applied or a brake fault is detected. If the light
does not illuminate, have the light inspected by an
authorized dealer.
The light also will turn on when the parking brake is
applied with the ignition is placed in the ON/RUN
position.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake application.

head unit. When the shift up indicator is shown on the
display, the PSI is advising the driver to engage a higher
gear.
NOTE:The PSI is configured and turned on or off in the
head unit “Shift Light: Set Up” page.
The PSI indicator in the cluster information display
remains illuminated until the driver changes gear, or the
driving conditions return to a situation where changing
gear is not required, corresponding to the configured
RPMs in the head unit.
NOTE: Refer to “Uconnect Settings” in “Understanding
Your Instrument Panel” for further information on en-
abling, disabling, and configuring the Performance Shift
Indicator.

•Prior to each track event/day, verify all fluids are at
the correct levels. Refer to “Fluid Capacities” in “Main-
taining Your Vehicle” for further information.
• Prior to each track event, verify the front and rear
brake pads have more than ½ pad thickness remain-
ing. If the brake pads require changing, please burnish
prior to track outing at full pace.
• At the conclusion of each track event, it is recom-
mended that a brake bleed procedure is performed to
maintain the pedal feel and stopping capability of your
Brembo High Performance brake system.
• It is recommended that each track outing should end
with a minimum of 1 cool down lap using minimal
braking.
• If equipped with a removable lower front fascia grille,
it is recommended to remove it for track use during warm/hot weather to improve cooling airflow to
critical powertrain and cooling system components.
• All SRT vehicles are track tested for 24 hours of
endurance, however, it is recommended that suspen-
sion system, brake system, prop shaft, and ½ shaft
boots should be checked for wear or damage after
every track event.
• Track usage results in increased operating tempera-
tures of the engine, transmission, driveline and brake
system. This may affect noise (NVH) countermeasures
designed into your vehicle. New components may
need to be installed to return the system to the original
NVH performance.
• Tire pressure:
• 40psi (276kpa) hot, recommend 32psi (221kpa) front,
30psi (207 kpa) rear cold

WARNING!(Continued)
high brake temperatures, excessive lining wear, and
possible brake damage. You would not have your full
braking capacity in an emergency.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be checked
whenever the vehicle is serviced, or immediately if the
brake system warning light is on. If necessary, add fluid
to bring level to the full mark on the side of the reservoir
of the brake master cylinder. Be sure to clean the top of
the master cylinder area before removing cap. With disc
brakes, fluid level can be expected to fall as the brake
pads wear. Brake fluid level should be checked when
pads are replaced. If the brake fluid is abnormally low,
check system for leaks. Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining 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
information. 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 identified on the
original factory installed hydraulic master cylinder
reservoir.
• To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that has
been in a tightly closed container. Keep the master
cylinder reservoir cap secured at all times. Brake
(Continued)
646 MAINTAINING YOUR VEHICLE

WARNING!(Continued)
fluid in a open container absorbs moisture from the
air resulting in a lower boiling point. This may
cause it to boil unexpectedly during hard or pro-
longed braking, resulting in sudden brake failure.
This could result in a collision.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing
the brake fluid to catch fire. Brake fluid can also
damage painted and vinyl surfaces, care should be
taken to avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.
Front/Rear Axle Fluid
For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons
the exterior surfaces of the axle assembly should be
inspected. If gear oil leakage is suspected inspect the
fluid level. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further informa-
tion.
Front Axle Fluid Level Check
The front axle oil level needs to be no lower than 1/8 in
(3 mm) below the bottom of the fill hole.
The front axle fill and drain plugs should be tightened to
22 to 29 ft lbs (30 to 40 N·m).7
