Brake System - Jeep COMPASS 2020 Owner's Manual

284 SERVICING AND MAINTENANCE
Maintain engine coolant (antifreeze) concen-

tration at a minimum of 50% OAT coolant
(conforming to MS.90032) and distilled water
for proper corrosion protection of your engine
which contains aluminum components.
Make sure that the coolant expansion bottle

overflow hoses are not kinked or obstructed.
Keep the front of the radiator clean. If your

vehicle is equipped with air conditioning,
keep the front of the condenser clean.
Do not change the thermostat for Summer or

Winter operation. If replacement is ever
necessary, install ONLY the correct type ther-
mostat. Other designs may result in unsatis-
factory engine coolant (antifreeze)
performance, poor gas mileage, and
increased emissions.

Brake System

In order to ensure 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!
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.
Brake Master Cylinder
The fluid in the master cylinder should be
checked when performing under hood services
or immediately if the "Brake Warning Light" is
illuminated.
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. 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. However, low fluid level may be
caused by a leak and a checkup may be
needed.
Use only manufacturer's recommended brake
fluid. Refer to "Fluids And Lubricants" in
"Technical Specifications" for further
information.
WARNING!
Use only manufacturer's recommended

brake fluid. Refer to "Fluids And Lubricants"
in "Technical Specifications" for further infor-
mation. 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 reser-
voir 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 unexpectedly during
hard or prolonged braking, resulting in
sudden brake failure. This could result in a
collision.
