Doing so may result in transmission damage or unexpected vehicle movement which could result in serious vehicle damage or personal injury. ¼ When driving straight, shift the AWD lock switch to OFF/AUTO or ON/LOCK. Do not operate the AWD lock switch when making a turn or backing up. ¼ Do not operate the AWD lock switch (OFF/AUTO and ON/LOCK) with the front wheel spinning. ¼ Engine idling speed is high while warming up the engine.

For driving on paved or slippery roads ON/LOCK AWD LOCK For driving on rough roads *1 LOCK mode will change to AUTO mode automatically, when the vehicle is accelerated or the vehicle speed is over approximately 19 MPH (30 km/h). The AWD LOCK indicator light does not go off. ¼ If the AWD LOCK switch is operated while accelerating or decelerating, or if the key switch is turned off while in the OFF/AUTO or ON/LOCK position, you may feel a jerk. This is normal. ¼ The oil temperature of power train parts will increase if the vehicle is continuously operated under conditions where the difference in rotation between the front and rear wheels is large (wheel slip) such as when driving the vehicle on rough roads through sand, mud or freeing a stuck vehicle. In these cases, the AWD warning light blinks rapidly and the AWD mode changes to 2WD to protect the power train parts. If you stop driving with the engine idling and wait until the warning light stops blinking, the AWD returns to the OFF/AUTO mode. Starting and driving 5-23
