2016 JEEP WRANGLER coolant reservoir

– 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 brake
system master cylinder 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 Tech-
nology (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.90032), 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
Component Fluid, Lubricant, or Genuine Part
Automatic Transmission – If Equipped
Use only ATF+4 Automatic Transmission
Fluid. Failure to use ATF+4 fluid may affect
the function or performance of your transmis-
sion. We recommend MOPAR ATF+4 fluid.
Manual Transmission – If EquippedWe recommend you use MOPAR Manual
Transmission Lubricant meeting the require-
ments of FCA US Material Standard MS-
9224.
Transfer Case We recommend you use MOPAR ATF+4
Automatic Transmission 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. For trailer towing,
use MOPAR Synthetic Gear & Axle Lubricant
(SAE 75W-140). Models equipped with Trac-
Lok require an additive.
Brake Master Cylinder We recommend you use MOPAR DOT 3
Brake Fluid, SAE J1703. 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 ATF+4 Auto-
matic Transmission Fluid.

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, powersteering 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.
