2. Using a small screwdriver or similar tool, remove theManual Park Release access cover, which is just above
the parking brake release handle, below and to the left
of the steering column.
3. Using the screwdriver or similar tool, push the Manual Park Release lever locking tab (just below the
middle of the lever) to the right.
4. While holding the locking tab in the disengaged position, pull the tether strap to rotate the lever
rearward, until it locks in place pointing towards the
driver’s seat. Release the locking tab and verify that
the Manual Park Release lever is locked in the released
position.
5. The vehicle is now out of PARK and can be towed. Release the parking brake only when the vehicle is
securely connected to a tow vehicle. To Reset The Manual Park Release:
1. Push the locking tab to the right, to unlock the lever.
2. Rotate the Manual Park Release lever forward to its
original position, until the locking tab snaps into place
to secure the lever.
3. Pull gently on the tether strap to confirm that the lever is locked in its stowed position.
4. Re-install the access cover.

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 abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You would not have your full
braking capacity in an emergency.
Brake Fluid Level Check
The fluid level of the master cylinder should be checked
when performing under the hood service or immediately
if the brake system warning lamp indicates system
failure.
The brake master cylinder has a translucent plastic
reservoir. On the outboard side of the reservoir, there is a
“MAX” dot and an “MIN” dot. The fluid level must be
kept within these two dots. Do not add fluid above the
MAX mark because leakage may occur at the cap.
With disc brakes the fluid level can be expected to fall as
the brake linings wear. However, an unexpected drop in
fluid level may be caused by a leak and a system check
should be conducted.
Use only the manufacturer’s recommended brake fluid.
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.

WARNING!
•Use only manufacturer’s recommended brake
fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further
information. Using the wrong type of brake fluid
can severely damage your brake system and/or
impair its performance. The proper type of brake
fluid for your vehicle is also identified on the
original factory installed hydraulic master cylinder
reservoir.
(Continued)
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 pro-
longed 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.

WARNING!(Continued)
•Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.
Rear Axle And 4x4 Front Driving Axle Fluid Level
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. This inspection should be made with the vehicle in
a level position. For 1500 Model axles, the fluid level should be even with
the bottom of the fill hole (within 1/4 in (6.4 mm) of edge
of hole) for the FDU215 HD front axle and C235FE rear
axle.
For all 2500/3500 Model axles, the fluid level should be
1/4 in ± 1/4 in (6.4 mm ± 6.4 mm) below the fill hole on
the 9.25 in front and 3/4 in ± 1/4 in (19 mm ± 6.4 mm) on
10.5 in rear axles. The 11.5 in rear axle level should be 1/4
in ± 1/4 in (6.4 mm ± 6.4 mm) below the fill hole.
Drain And Refill
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
Lubricant Selection
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
