2018 JEEP WRANGLER UNLIMITED automatic transmission

light is on. If necessary, add fluid to bring
level within the designated marks on the side
of the reservoir of the brake master cylinder.
Be sure to clean the top of the master cylin-
der area before removing cap. 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. If the
brake fluid is abnormally low, check the sys-
tem for leaks.
Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for further information.
WARNING!
• Brake fluid is poisonous and highly cor-
rosive. In the event of accidental con-
tact, immediately wash the affected
parts with water and neutral soap. Then
rinse thoroughly. Call a doctor immedi-
ately if swallowed.
• Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubri-
cants” in “Technical Specifications” for
further information. Using the wrong
type of brake fluid can severely damage
WARNING!
your brake system and/or impair its per-
formance. The proper type of brake fluid
for your vehicle is also identified on the
original factory installed hydraulic mas-
ter 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 cylin-
der 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 cause it to boil
unexpectedly during hard or prolonged
braking, resulting in sudden brake fail-
ure. This could result in a collision.
• Overfilling the brake fluid reservoir can
result in spilling brake fluid on hot en-
gine 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
WARNING!
components could be damaged, causing
partial or complete brake failure. This
could result in a collision.
Automatic Transmission
Fluid Level Check
The fluid level is preset at the factory and
does not require adjustment under normal
operating conditions. Routine fluid level
checks are not required; therefore the trans-
mission has no dipstick. An authorized dealer
can check your transmission fluid level using
special service tools. If you notice fluid leak-
age or transmission malfunction, visit an au-
thorized dealer immediately to have the
transmission fluid level checked. Operating
the vehicle with an improper fluid level can
cause severe transmission damage.
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An au-

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 an-
tirust products, as they may not be com-
patible 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
CAUTION!
glycol-based engine coolant (antifreeze)
is not recommended.
• The use of products with different speci-
fications than those indicated above
could cause damage to the engine that
is not covered by the warranty.
• Use AdBlue only according to DIN
70 070 and ISO 22241-1. Other fluids
may cause damage to the system: also
exhaust emissions would no longer com-
ply with the law.
CAUTION!
• The distribution companies are respon-
sible for the compliance of their prod-
uct. Observe the precautions of storage
and servicing, in order to preserve the
initial qualities. The manufacturer of the
vehicle does not recognize any guaran-
tee in case of malfunctions and damage
caused to the vehicle due to the use of
UREA (AdBlue) not in accordance with
regulations.
