rized dealer for service as soon as possible. If the light is
flashing when the engine is running, immediate service is
required. You may experience reduced performance, an
elevated/rough idle or engine stall and your vehicle may
require towing.

gear reduction ratio to provide increased torque at the
wheels.

and proper use, refer to “Four-Wheel Drive Operation —
If Equipped” in “Starting And Operating”.
