438 SERVICING AND MAINTENANCE
(Continued)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.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be checked
when performing under the hood service or immediately if
the brake system warning lamp indicates system failure.
If necessary, add fluid to bring level within the designated
marks 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 the fluid level can be expected to fall as the
brake linings wear. However, an unexpected drop in fluid
level may be caused by a leak and a system check should be
conducted.
Refer to “Fluids And Lubricants” in “Technical Specifica -
tions” for further information.
WARNING!
Riding the brakes can lead to brake failure and possibly
a collision. 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. WARNING!
• Use only manufacturer's recommended brake fluid.
Refer to “Fluids And Lubricants” in “Technical Speci -
fications” 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 mois -
ture, 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 fluid in a open
container absorbs moisture from the air resulting in a
lower boiling point. This may cause it to boil unexpect -
edly during hard or prolonged braking, resulting in
sudden brake failure. This could result in a collision.

464 SERVICING AND MAINTENANCE
Wheel And Wheel Trim Care
All wheels and wheel trim, especially aluminum and chrome
plated wheels, should be cleaned regularly using mild
(neutral Ph) soap and water to maintain their luster and to
prevent corrosion. Wash wheels with the same soap solution
recommended for the body of the vehicle and remember to
always wash when the surfaces are not hot to the touch.
Your wheels are susceptible to deterioration caused by salt,
sodium chloride, magnesium chloride, calcium chloride, etc.,
and other road chemicals used to melt ice or control dust on
dirt roads. Use a soft cloth or sponge and mild soap to wipe
away promptly. Do not use harsh chemicals or a stiff brush.
They can damage the wheel’s protective coating that helps
keep them from corroding and tarnishing. 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 damage
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.
NOTE:
If you intend parking or storing your vehicle for an extended
period after cleaning the wheels with wheel cleaner, drive
your vehicle and apply the brakes to remove the water drop -
lets from the brake components. This activity will remove the
red rust on the brake rotors and prevent vehicle vibration
when braking.CAUTION!
Avoid products or automatic car washes that use acidic
solutions or strong alkaline additives or harsh brushes.
Many aftermarket wheel cleaners and automatic car
washes may damage the wheel's protective finish. Such
damage is not covered by the New Vehicle Limited
Warranty. Only car wash soap, Mopar Wheel Cleaner or
equivalent is recommended. CAUTION!
Do not use scouring pads, steel wool, a bristle brush,
metal polishes or oven cleaner. These products may
damage the wheel's protective finish. Such damage is not
covered by the New Vehicle Limited Warranty. Only car
wash soap, Mopar Wheel Cleaner or equivalent is
recommended.

476 TECHNICAL SPECIFICATIONS
BRAKE SYSTEM
If power assist is lost for any reason (for example, repeated
brake applications with the engine off), the brakes will still
function. However, you will experience a substantial
increase in braking effort to stop the vehicle.
If either the front or rear hydraulic system loses normal
braking capability, the remaining system will still function
with some loss of overall braking effectiveness. This will be
evident by increased pedal travel during application, greater
pedal force required to slow or stop, and activation of the
“Brake Warning Light” and the “ABS Warning Light” (if
equipped) during brake use.
The brake system power assist is provided by a hydro-boost
unit which shares fluid with the power steering system. You
may experience some clicking or hissing noises from the
hydro-boost system during hard braking conditions.
NOTE:
Under cold temperatures, pedal effort will be higher than
normal until the power steering fluid reaches operating
temperature. Hydraulic Brake Assist
The brake system power assist is provided by a hydro-boost
unit which shares fluid with the power steering system. You
may experience some clicking or hissing noises from the
hydro-boost system during hard braking conditions.
NOTE:
Under cold temperatures, pedal effort will be higher than
normal until the power steering fluid reaches operating
temperature.
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 calibrated
torque wrench using a high quality six sided (hex) deep wall
socket.
