Compass System (U.S. model without navigation system) Keyless Memory SettingsTM The vehicle ''senses'' the driver number, based on which keyless remote is used to unlock the vehicle. If two drivers with remotes approach the vehicle at the same time, the welcome display and related settings are based on which remote the vehicle first ''senses.'' NOTE: If both remotes come within range simultaneously, the ''Welcome'' display may be unpredictable. The compass system uses the driver number (as recognized by the multiinformation display) to personalize the compass system. For example, if Driver 1 unlocks the vehicle, the ''Driver 1'' personal address book and other navigation settings are automatically loaded when the vehicle is started. There is no way to change from one driver's settings to another while driving. When the keyless access remote is deliberately ''unlinked,'' (as when giving the remote without the built-in key to a valet) the multi-information display will display ''Welcome.'' Then the following occurs: The calendar feature is not selectable (buttons grayed out). Setup values (like volume, brightness, etc.) can be changed but are not remembered the next time you restart the vehicle. For information on ''linking'' and ''unlinking'' the keyless access remotes, see page 174 . Features 285
