Two-Speed Rear Axle
1. With the engine running, shift the two-speed rear
axle into low. To be sure it is in low, you will need
to move the vehicle in gear just a little.
2. Hold the regular brake pedal down with your
right foot.
3. Apply the parking brake.
4. Shift the transmission to NEUTRAL for manual
transmission or PARK (P) for automatic
transmission.
Hydraulic Brakes (Parking Brake
Operation)
If your vehicle has hydraulic brakes, it has a parking
brake lever. The lever is located in the center console.
Your vehicle may also be equipped with an automatic
transmission which has a center console shift lever. This
lever will have a PARK (P) position on the shift indicator.
Even when PARK (P) is selected, be sure to apply the
parking brake firmly so the vehicle will not move.

Propshaft Brake Burnish Procedure

It is recommended that the propshaft-mounted parking
brake be burnished as part of the new vehicle break-in.
The parking brake will work best after it has been
burnished following these instructions:
1. Make 10 stops, using the parking brake hand
lever, from 20 mph (32 km/h) about
2 1/2 miles (4 km) apart.
2. Between stops, drive the vehicle at
20 mph (32 km/h).

Parking Brake

To apply the parking brake, pull the lever all the way up.
The park brake light will come on when the parking
brake is applied. See Brake System Warning Light on
page 3-27 for more information. Then shift the
transmission to NEUTRAL for a manual transmission or
PARK (P) for an automatic transmission. The vehicle
must be stationary when applying the parking brake,
except while burnishing the parking brake linings. See
Propshaft Brake Burnish Procedure on page 2-20
for more information.
