Power Electronics And Battery Thermal
Management Systems — Cooling Pressure Caps
The caps must be fully tightened to prevent loss of
coolant (antifreeze).
The caps should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
NOTE:
•The pressure caps on the reservoirs are unique and
rated at 5 PSI caps.
• Use only Mopar replacement parts.
WARNING!
•The warning words “DO NOT OPEN HOT” on
the cooling system pressure cap are a safety
precaution. Never add coolant (antifreeze) when
the cooling system is overheated. Do not loosen or
remove the cap to cool an overheated cooling
system. Heat causes pressure to build up in the
cooling system. To prevent scalding or injury, do
not remove the pressure cap while the system is
hot or under pressure.

WARNING! (Continued)
•Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or
vehicle damage may result.
Selection Of Coolant
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information.
CAUTION!
• Mixing of coolant (antifreeze) other than speci-
fied Organic Additive Technology (OAT) coolant
(antifreeze), may result in cooling system damage
and may decrease corrosion protection. Organic
Additive Technology (OAT) coolant is different
and should not be mixed with Hybrid Organic
Additive Technology (HOAT) coolant (anti-
freeze). If a non-OAT coolant (antifreeze) is intro-
duced into the cooling system in an emergency, it
should be replaced with the specified coolant
(antifreeze) as soon as possible.

Adding Washer Fluid
The windshield washer fluid reservoir is located in the
underhood compartment, and the fluid level should be
checked at regular intervals. Fill the reservoir with
windshield washer solvent (not coolant/antifreeze).
Refer to “Underhood Compartment” in “Maintaining
Your Vehicle” for further information.
WARNING!
Commercially available windshield washer sol-
vents are flammable. They could ignite and burn
you. Care must be exercised when filling or work-
ing around the washer solution.
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 abnor-
mally high brake temperatures, excessive lining
wear, and possible brake damage. Riding the
brakes may also reduce braking capacity in an
emergency.
Brake Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately
if the “Brake Warning Light” is on and the parking
brake is not applied.
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. Fluid level can be expected to fall
as the brake pads wear. The brake fluid level should be
checked when the pads are replaced. However, low
fluid level may be caused by a leak and a checkup may
be needed.7

MAINTENANCE SCHEDULE
Once A Month Or Before A Trip:
•Check windshield washer fluid level
• Check the tire inflation pressures and look for un-
usual wear or damage
• Check the fluid levels of the coolant reservoirs and
brake master cylinder
• Check function of all interior and exterior lights
Maintenance Chart
Required Maintenance Intervals
Refer to the maintenance schedules on the following
page for the required maintenance intervals.
At Every Service Interval:
• Rotate the tires. Rotate at the first sign of
irregular wear.
• Inspect brake pads, shoes, rotors, drums, and
hoses.
• Inspect battery cooling system protection and
hoses.
• Check and adjust hand brake.
