NOTE:Flashing neutral (N) position indicator light
indicates that shift requirements have not been met.
CAUTION!
Damage to the transmission may occur if the trans-
mission is shifted into Park (P) with the transfer case
in Neutral (N) and the engine RUNNING. With the
transfer case in Neutral (N) ensure that the engine is
OFF prior to shifting the transmission into Park (P).
Returning to Normal Operation — Electronic Shift
Transfer Case
Use the following procedure to prepare your vehicle for
normal usage.
1. Bring vehicle to a complete stop.
2. Shut OFF the engine. 3. Turn the ignition key to the ON position, but do not
start the engine.
4. Depress the brake pedal.
5. Shift automatic transmission to Neutral (N) or depress
clutch on manual transmission.
6. Using the point of a ballpoint pen or similar object,
depress the recessed transfer case Neutral (N) button for
1 second.
7. After the Neutral (N) indicator light turns off release
the Neutral (N) button.
8. After the Neutral (N) button has been released the
transfer case will shift to the position identified by the
selector switch.
9. Shift automatic transmission into P (Park).
NOTE:
The transfer case can not be shifted into Neutral
(N) from the 4Auto (if equipped) position.

424 MAINTAINING YOUR VEHICLE
WARNING!
Use of a brake fluid that may have a lower initial
boiling point, or is unidentified as to specification,
may result in sudden brake failure during hard
prolonged braking. You could have an accident.
WARNING!
Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts and the
brake fluid catching fire.
Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign matter or
moisture.
CAUTION!
Do not allow a petroleum-base fluid to contaminate
the brake fluid. Seal damage may result.
Brake Hoses
Inspection should be performed whenever the brake
system is serviced or at intervals specified. Inspect hy-
draulic brake hoses for surface cracking, scuffing or worn
spots. If there is any evidence of cracking, scuffing, or
worn spots, the hose should be replaced immediately!
Eventual deterioration of the hose can take place with
possible burst failure.
Clutch Hydraulic System
The clutch hydraulic system is a sealed maintenance-free
system. In the event of leakage or other malfunction, the
system must be replaced.

Clutch Linkage
If the clutch pedal linkage begins to squeak or grunt, the
clutch pedal pivot bushings should be lubricated. Refer
to Fluids, Lubricants and Genuine Parts for the correct
lubricant type.
Rear Axle And 4x4 Front Driving Axle Fluid Level
Refer to Fluids, Lubricants and Genuine Parts for the
correct Fluid type. 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.
This inspection should be made with the vehicle in a level
position. The fluid level should be even with the bottom
of the fill hole for the Manufacturer’s C205F HD Front
Axles. The fluid level should be 5/8” (16 mm) below on
9 1/4” Manufacturer’s Rear Axles. For all 2500/3500 Model axles, the fluid level should be
1/4” ± 1/4” (6.4 mm ± 6.4 mm) below the fill hole on the
9.25” Front and 3/4”± 1/4” (19 mm ± 6.4 mm) on 10.5”
Rear axles. The 11.5” Rear Axle level should be 1/4” ±
1/4” (6.4 mm ± 6.4 mm) below the fill hole.
Drain and Refill
Vehicles operated in normal service do not have regularly
scheduled oil changes. If fluid has become contaminated
with water or to provide the correct viscosity grade, drain
and refill.
Lubricant Selection
Refer to Fluids, Lubricants and Genuine Parts for correct
fluid type.
NOTE:
The presence of water in the gear lubricant will
result in corrosion and possible failure of differential
components. Operation of the vehicle in water, as may be
encountered in some off-highway types of service, will
require draining and refilling the axle to avoid damage.
