Driving your vehicle ALL Wheel Drive (AWD) transfer mode selection Transfer mode Selection button Indicator light Description • When driving in AWD AUTO mode, the vehicle operates similar to conventional 2WD vehicles under normal operating conditions. However, if the system determines that there is a need for the AWD mode, the engine's driving power is distributed to all four wheels automatically without driver intervention. • When driving on normal roads and pavement, the vehicle moves similar to conventional 2WD vehicles. • This mode is used for climbing or descending sharp grades, off-road driving, driving on sandy and muddy roads, etc., to maximize traction. • This mode automatically begins to deactivate at speeds above 19 mph (30 km/h) and is shifted to AWD AUTO mode at speed above 25 mph (40 km/h). If the vehicle decelerates to speeds below 19 mph (30 km/h), however, the transfer mode is shifted into AWD LOCK mode again. AWD AUTO (AWD LOCK is deactivated) (Indicator light is not illuminated) AWD LOCK (Indicator light is illuminated) ✽ NOTICE • When driving on normal roads, deactivate the AWD LOCK mode by pushing the AWD LOCK button (the indicator light goes off). Driving on normal roads with AWD LOCK mode(especially, when cornering) may cause mechanical noise or vibration. The noise and vibration will disappear when the AWD LOCK mode is deactivated. Some parts of the power train may be damaged by prolonged driving with the noise and vibration. • When the AWD LOCK mode is deactivated, a shock may be felt as the drive power is delivered entirely to the front wheels. This shock is not a mechanical failure. 5 18
