2015 JEEP WRANGLER brake fluid

- Engine Temperature Warning Light
This light warns of an overheated engine condition.
If the light turns on and a warning chime sounds while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also, shift the transmission into
NEUTRAL and idle the vehicle. If the temperature reading does not return to normal,
turn the engine off immediately.
We recommend that you do not operate the vehicle or engine damage will occur. Have
the vehicle serviced immediately.
WARNING!
A hot engine cooling system is dangerous. You or others could be badly burned by
steam or boiling coolant.
- Brake Warning Light
This light monitors various brake functions, including brake fluid level and parking
brake application. If the brake light turns on it may indicate that the parking brake is
applied, that the brake fluid level is low, or that there is a problem with the anti-lock
brake system reservoir.
If the light remains on when the parking brake has been disengaged, and the fluid
level is at the full mark on the master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the Brake Booster has been
detected by the Anti-Lock Brake System (ABS)/Electronic Stability Control (ESC)
system. In this case, the light will remain on until the condition has been corrected.
If the problem is related to the brake booster, the ABS pump will run when applying
the brake and a brake pedal pulsation may be felt during each stop.
The dual brake system provides a reserve braking capacity in the event of a failure to
a portion of the hydraulic system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on when the brake fluid level
in the master cylinder has dropped below a specified level. The light will remain on
until the cause is corrected.
Vehicles equipped with the Anti-Lock Brake System (ABS), are also equipped with
Electronic Brake Force Distribution (EBD). In the event of an EBD failure, the Brake
Warning Light will turn on along with the ABS Light. Immediate repair to the ABS
system is required.
Operation of the Brake Warning Light can be checked by turning the ignition switch
from the OFF position to the ON/RUN position. The light should illuminate for
approximately two seconds. The light should then turn off unless the parking brake
is applied or a brake fault is detected. If the light does not illuminate, have the light
inspected by an authorized dealer.

CAUTION!
• Mixing of engine coolant (antifreeze) other than specified Organic Additive
Technology (OAT) engine coolant (antifreeze), may result in engine damage and
may decrease corrosion protection. Organic Additive Technology (OAT) engine
coolant is different and should not be mixed with Hybrid Organic Additive
Technology (HOAT) engine coolant (antifreeze) or any “globally compatible”
coolant (antifreeze). If a non-OAT engine coolant (antifreeze) is introduced into
the cooling system in an emergency, the cooling system will need to be drained,
flushed, and refilled with fresh OAT coolant (conforming to MS-12106), by an
authorized dealer as soon as possible.
• Do not use water alone or alcohol-based engine coolant (antifreeze) products.
Do not use additional rust inhibitors or antirust products, as they may not be
compatible with the radiator engine coolant and may plug the radiator.
• This vehicle has not been designed for use with propylene glycol-based engine
coolant (antifreeze). Use of propylene glycol-based engine coolant (antifreeze)
is not recommended.
Chassis
ComponentFluid, Lubricant, or Genuine Part
Automatic Transmission –If EquippedUse only ATF+4®Automatic Transmission Fluid. Failure touse ATF+4®fluid may affect the function or performance ofyour transmission. We recommend MOPAR®AT F + 4®fluid.
Manual Transmission –If EquippedWe recommend you use MOPAR®Manual Transmission Lubri-cant meeting the requirements of Chrysler Material StandardMS-9224.
Transfer CaseWe recommend you use MOPAR®AT F + 4®Automatic Trans-mission Fluid.
Axle Differential (Front) We recommend you use MOPAR®Gear & Axle Lubricant(SAE 80W-90) (API GL-5).
Axle Differential (Rear)226 RBI (Model 44)–We recommend you use MOPAR®Gear& Axle Lubricant (SAE 80W-90) (API GL-5) or equivalent. Fortrailer towing, use MOPAR®Synthetic Gear & Axle Lubricant(SAE 75W-140). Models equipped with Trac-Lok™ require anadditive.
Brake Master Cylinder We recommend you use MOPAR®DOT 3 Brake Fluid, SAEJ1703. If DOT 3, SAE J1703 brake fluid is not available,then DOT 4 is acceptable.
Power Steering Reservoir We recommend you use MOPAR®Power Steering Fluid +4,MOPAR®AT F + 4®Automatic Transmission Fluid.

Severe Duty All Models
Change Engine Oil at 4000 miles (6,500 km) if the vehicle is operated in a dusty and
off road environment. This type of vehicle use is considered Severe Duty
Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look for unusual wear or damage
• Check the fluid levels of the coolant reservoir, brake master cylinder, power
steering and automatic transmission, and fill as needed
• Check function of all interior and exterior lights
Required Maintenance Intervals.
Refer to the maintenance schedules on the following page for the required mainte-
nance intervals.
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 automatic transmission fluid if equipped with dipstick
•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
•Inspect all door latches for presence of grease, reapply if necessary.
