Front/Rear Axle Fluid - Jeep Grand Cherokee 2011 Owner's Manual

WARNING! (Continued)
• 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 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
failure. This could result in a collision.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine 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 contami-
nate the brake fluid. Brake seal components could
be damaged, causing partial or complete brake
failure. This could result in a collision.

Front/Rear Axle Fluid

For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons
the exterior surfaces of the axle assembly should be
inspected. If gear oil leakage is suspected inspect the
fluid level. Refer to "Fluids, Lubricants, and Genuine
Parts" in "Maintaining Your Vehicle" for further informa-
tion.
Front Axle Fluid Level Check
(Continued) The front axle oil level needs to be between 1/8 in (3 mm)
below the bottom of the fill hole and the bottom of the fill
hole.
