FRONT SONAR SYSTEM OFF SWITCH (If so equipped) The system will automatically reset the next time the ignition switch is turned on. See "Front sonar system" in the "Starting and driving" section. TOW MODE SWITCH LIC1182 LIC0594 WARNING The front sonar system is a convenience but it is not a substitute for proper driving. The front sonar system is active when the ignition is in the ON position and the shift selector is in a forward gear position. When sensors detect obstacles within 3 ft (1.0 m) of the front bumper, a beeping tone is emitted. The front sonar system can be disabled by pushing the OFF switch. When the system is disabled, the indicator light on the switch will illuminate. Push the switch again to enable the system. The indicator light will go off. Tow mode should be used when pulling a heavy trailer or hauling a heavy load. Driving the vehicle in the tow mode with no trailer/load or light trailer/light load will not cause any damage. However, fuel economy may be reduced, and the transmission/engine driving characteristics may feel unusual. Press the tow mode switch to activate tow mode. The indicator light on the tow mode switch illuminates when tow mode is selected. Press the tow mode switch again to turn tow mode OFF. Tow mode is automatically canceled when the ignition switch is placed in the OFF position. Instruments and controls 2-33
