2019 JEEP GRAND CHEROKEE LIMITED brake

At Every Oil Change Interval As Indicated By Oil Change Indicator System:
•Change oil and filter.
• Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil indicator system turns
on.
• Inspect battery and clean and tighten terminals as required.
• Inspect brake pads, shoes, rotors, drums, hoses and park brake.
• Inspect engine cooling system protection and hoses.
• Inspect exhaust system.
• Inspect engine air cleaner if using in dusty or off-road conditions.

SERVICING AND MAINTENANCE 439

Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically. Refer
to the “Maintenance Plan” in this section for the proper
maintenance intervals.

WARNING!(Continued)
•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.
Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life. Use
only the manufacturer’s specified transmission fluid. Refer
to “Fluids And Lubricants” in “Technical Specifications”
for fluid specifications. It is important to maintain the
transmission fluid at the correct level using the recom-
mended fluid.
NOTE: No chemical flushes should be used in any trans-
mission; only the approved lubricant should be used.

When cleaning extremely dirty wheels including excessive
brake dust, care must be taken in the selection of tire and
wheel cleaning chemicals and equipment to prevent dam-
age to the wheels. Mopar Wheel Treatment or Mopar
Chrome Cleaner or their equivalent is recommended or
select a non-abrasive, non-acidic cleaner for aluminum or
chrome wheels.
CAUTION!
If your vehicle is equipped with these specialty
wheels, DO NOT USE wheel cleaners, abrasives, or
polishing compounds. They will permanently damage
this finish and such damage is not covered by the New
Vehicle Limited Warranty. HAND WASH ONLY US-
ING MILD SOAP AND WATER WITH A SOFT
CLOTH. Used on a regular basis; this is all that is
required to maintain this finish.
Tire Chains (Traction Devices)
Use of traction devices require sufficient tire-to-body clear-
ance. Follow these recommendations to guard against
damage.
•Traction device must be of proper size for the tire, as
recommended by the traction device manufacturer.
• Install on Rear Tires Only
• Due to limited clearance, Thule XG-12 Pro or equivalent
is recommended on P245/70R17, 265/60R18 or 265/
50R20 tires.
488 SERVICING AND MAINTENANCE

NOTE:It is illegal to remove or alter the VIN.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake sys-
tems. If either of the two hydraulic systems loses normal
capability, the remaining system will still function. How-
ever, there will be some loss of overall braking effective-
ness. You may notice increased pedal travel during appli-
cation, greater pedal force required to slow or stop, and
potential activation of the Brake Warning Light. In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine OFF) the
brakes will still function. However, the effort required to
brake the vehicle will be much greater than that required
with the power system operating.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure that
the wheel is properly mounted to the vehicle. Any time a
wheel has been removed and reinstalled on the vehicle, the
lug nuts/bolts should be torqued using a properly cali-
brated torque wrench using a high quality six sided (hex)
deep wall socket.

Forward Collision
Warning — If Equipped Off
Warning Only Warning & Braking
NOTE:
Changing the FCW status to “Off” prevents the system from warning you of a possible collision with the vehicle in
front of you.
The FCW system state is kept in memory from one ignition cycle to the next. If the system is turned OFF, it will re-
main off when the vehicle is restarted.
Forward Collision Warning includes Advanced Brake Assist (ABA). The ABA applies additional brake pressure when
the driver requests insufficient brake pressure to avoid a potential frontal collision. When the “Sound Only” option is
selected a chime sounds alerting you of a possible collision with the vehicle in front of you and more brake pressure
is needed. When the “Sound and Brake” option is selected, it applies the brakes to slow your vehicle in case of poten-
tial forward collision and sound an audible chime to alert you. Forward Collision
Warning Sensitivity — If Equipped Far
Med Near
NOTE:
The “Forward Collision Warning Sensitivity” setting determines at what relative distance the vehicle directly in front
of you needs to be at, before the system warns you of a possible collision with the vehicle directly in front of you,
based on the option is selected. “Far” gives you the most amount of reaction time, whereas “Near” will give you the
least amount of reaction time, based on the distance between the two vehicles.
