AWD LOCK switch Wheel driven AWD LOCK indicator light Use conditions WARNING ¼ Do not start engine while in the AUTO or LOCK mode in the following cases: When on free roller or jacking up the front tire with the rear tires on the ground. ¼ When driving straight, shift the AWD lock switch to AUTO or LOCK. Do not operate the AWD lock switch when making a turn or reversing. ¼ Do not operate the AWD lock switch (AUTO and LOCK) with the front wheel spinning. ¼ Engine idling speed is high while warming up the engine. Be especially careful when starting or driving on slippery surfaces with the AWD lock switch set in OFF (AUTO). ¼ When turning the vehicle in LOCK mode on paved roads, you may feel a braking effect. This is a normal condition of the AWD model. Distribution of torque to the front and rear wheels changes automatically, depending on road conditions enAUTO (OFF) countered [100:0]↔[50:50]. This results in improved driving stability. LOCK (ON) *1 ALL wheel drive Goes off. For driving on paved or slippery roads 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 AUTO or 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 AUTO mode. 5-18 Starting and driving
