Safety Timer
This option can be used to keep the phone on for a set period
after the vehicle ignition has been turned off. This prevents the
vehicle's battery from becoming drained and saves you from
having to re-enter PIN and Unlock codes after every short stop.
As standard the 'Safety Timer' is set to 60 minutes. Once
selected, this option can be adjusted to any value between zero
and 999 minutes. When set to zero, this option is effectively
switched off.
Auxiliary Alert
This option allows your phone to alert you of an incoming call by
flashing your vehicle lights, or by sounding the horn. It must be
enabled by your local dealer.
A Some local regulations prevent the use of this option and,
accordingly, this option may not be present on your phone.
