warning JEEP WRANGLER UNLIMITED 2013 Owners Manual

Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
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. Power Disc Brakes
Disc brakes do not require adjustment; however, several
hard stops during the break-in period are recommended
to seat the linings and wear off any foreign material.
Brake Master Cylinder
The fluid level in the master cylinders should be checked
whenever the vehicle is serviced. If necessary, add fluid
to bring level to the full level mark on the side of the
reservoir of the brake master cylinder. With disc brakes,
fluid level can be expected to fall as the brake pads wear.
If the brake fluid level is abnormally low, check system
for leaks.
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
7 MAINTAINING YOUR VEHICLE 583

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
fluid in a open container absorbs moisture from the
air resulting in a lower boiling point. This may (Continued) WARNING! (Continued)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.584 MAINTAINING YOUR VEHICLE

Interior Care
Use MOPAR  Total Clean or equivalent to clean fabric
upholstery and carpeting.
Interior Trim should be cleaned starting with a damp
cloth, a damp cloth with MOPAR  Total Clean or equiva-
lent , then MOPAR  Spot & Stain Remover or equivalent
if absolutely necessary. Do not use harsh cleaners or
Armor All  . Use MOPAR  Total Clean or equivalent to
clean vinyl upholstery.
WARNING!Do not use volatile solvents for cleaning purposes.
Many are potentially flammable and, if used in
closed areas, they may cause respiratory harm. CAUTION!When installing hanging air fresheners in your ve-
hicle, read the installation instructions carefully.
Some air fresheners will damage the finish of
painted or decorated parts if allowed to directly
contact any surface.
Glass Surfaces
All glass surfaces should be cleaned on a regular basis
with MOPAR  Glass Cleaner or equivalent, or any com-
mercial household-type glass cleaner. Never use an abra-
sive type cleaner. Use caution when cleaning the inside
rear window equipped with electric defrosters or the
right rear quarter window equipped with the radio
antenna. Do not use scrapers or other sharp instrument
that may scratch the elements.594 MAINTAINING YOUR VEHICLE

WARNING!• You can be badly injured working on or around a
motor vehicle. Do only service work for which you
have the knowledge and the right equipment.
If you have any doubt about your ability to per-
form a service job, take your vehicle to a competent
mechanic.
• Failure to properly inspect and maintain your
vehicle could result in a component malfunction
and effect vehicle handling and performance. This
could cause an accident.

Traction Grades
The Traction grades, from highest to lowest, are AA, A, B,
and C. These grades represent the tire’s ability to stop on
wet pavement, as measured under controlled conditions on
specified government test surfaces of asphalt and concrete.
A tire marked C may have poor traction performance.
WARNING!The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not
include acceleration, cornering, hydroplaning, or
peak traction characteristics.
Temperature Grades
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation of heat
and its ability to dissipate heat, when tested under controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire failure. The
grade C corresponds to a level of performance, which all
passenger car tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades B and A repre-
sent higher levels of performance on the laboratory test
wheel, than the minimum required by law.
WARNING!The temperature grade for this tire is established for
a tire that is properly inflated and not overloaded.
Excessive speed, under-inflation, or excessive load-
ing, either separately or in combination, can cause
heat buildup and possible tire failure.632 IF YOU NEED CONSUMER ASSISTANCE
