case, located in this section of the Owner’s Manual. The “Service 4WD Warning Light” monitors the electric
shift four-wheel drive system. If this light remains on
after engine start up or illuminates during driving, it
means that the four-wheel drive system is not function-
ing properly and that service is required.

down the vehicle if the
\bService 4WD Warning Light”
is illuminated. Not engaging the parking brake may
allow the vehicle to roll which may cause personal
injury.

3 mph (3 to 5 km/h) or completely stopped. USE EITHER
OF THE FOLLOWING PROCEDURES:
Preferred Procedure
1. With the engine running, slow the vehicle to 2 to
3 mph (3 to 5 km/h).
2. Shift the transmission into NEUTRAL.
3. While still rolling, rotate the transfer case switch to the
desired position.
4. After the desired “Transfer Case Position Indicator
Light” is ON (not flashing), shift the transmission back
into gear.

position.
4. After the desired “Transfer Case Position Indicator
Light” is ON (not flashing), shift the transmission back
into gear.NOTE:
•
If steps 1 or 2 of either the Preferred or Alternate
Procedure are not satisfied, prior to attempting the
shift, or if they no longer are being met while the shift
attempt is in process, then the desired “Transfer Case
Position Indicator Light” will flash continuously while
the original “Transfer Case Position Indicator Light” is
ON, until all requirements have been met.
