Driving The ESOF 4WD system: • provides 4x4 High engagement and disengagement while the vehicle is moving. • is operated by a rotary control located on the instrument panel that allows you select 4x2, 4x4 High or 4x4 Low operation. • uses auto-manual hub locks that can be engaged and disengaged automatically based on the 4x4 mode selected. • auto-manual hub locks can be manually overridden by rotating the hub lock control from AUTO to LOCK if desired. • automatic operation of the hub locks is recommended, and will increase fuel economy • For proper operation, make sure that each hub is fully engaged and that both hub locks are set to the same position (both set to LOCK or both set to AUTO). To engage LOCK, turn the hub locks completely clockwise; to engage AUTO, turn the hub locks completely counterclockwise. 4WD system indicator lights The indicator lights illuminate in the message center in the reconfigurable telltale (RTT) under the following conditions.
