HORN VEHICLE DYNAMIC CONTROL (VDC) OFF SWITCH (if so equipped) HILL DESCENT CONTROL SWITCH (if so equipped) LIC0604 WIC0534 LIC0743 To sound the horn, push the area near the horn icons on the steering wheel. The vehicle should be driven with the Vehicle Dynamic Control (VDC) system on for most driving conditions. If the vehicle is stuck in mud or snow, the VDC system reduces the engine output to reduce wheel spin. The engine speed will be reduced even if the accelerator is depressed to the floor. If maximum engine power is needed to free a stuck vehicle, turn the VDC system off. To turn off the VDC system, push the VDC OFF switch. The indicator will come on. Push the VDC OFF switch again or restart the engine to turn on the system. See "Vehicle Dynamic Control (VDC) system" in the "Starting and driving" section. WARNING ● Never rely solely on the hill descent control system to control vehicle speed when driving on steep downhill grades. Always drive carefully when using the hill descent control system and decelerate the vehicle speed by depressing the brake pedal if necessary. Be especially careful when driving on frozen, muddy or extremely steep downhill roads. Failure to control vehicle speed may result in a loss of control of the vehicle and possible serious injury or death. WARNING Do not disassemble the horn. Doing so could affect proper operation of the supplemental front air bag system. Tampering with the supplemental front air bag system may result in serious personal injury.
