Controls in detail Locking and unlocking Important notes on using KEYLESS-GO You can also use the SmartKey with KEYLESS-GO like a normal SmartKey ( page 94). You can combine KEYLESS-GO functions with normal SmartKey functions (e.g. unlocking with KEYLESS-GO and locking with the Πbutton). Always carry the SmartKey with KEYLESS-GO with you. Never store the SmartKey with KEYLESS-GO together with: Electronic items such as a cellular phone or another SmartKey with KEYLESS-GO Metallic objects such as coins or metal foil Doing so could impair the function of the KEYLESS-GO system. To lock or unlock the vehicle, the SmartKey with KEYLESS-GO must be located outside the vehicle within approximately 3 ft (1 m) of a door or the trunk. In order to start the engine with the SmartKey with KEYLESS-GO: The SmartKey with KEYLESS-GO must be located in the vehicle. All doors must be closed. The brake pedal must be firmly depressed. Do not depress the accelerator. If you have started the engine with the KEYLESS-GO start/stop button ( page 37), you can only turn it off again with this button, even if you have put the SmartKey in the starter switch in the meantime. This does not apply if, after starting, the selector lever is still in position P and the SmartKey is then inserted in the starter switch. The SmartKey will then have priority over the KEYLESS-GO function and the vehicle's electrical system will operate according to the position of the SmartKey in the starter switch, even stopping the engine. If the SmartKey with KEYLESS-GO is positioned farther away from the vehicle, the system may no longer recognize the SmartKey with KEYLESS-GO. The vehicle then cannot be locked or the engine started via the KEYLESS-GO system. 101
