ALARM SYSTEM AND HORN
DESCRIPTION AND OPERATION 86-4-11
Central door locking switches
A momentary action switch mounted on the fascia allows for central door locking/unlocking from within the vehicle.
The switch is mounted adjacent to the clock.
Input/Output
The input from the central door locking/unlocking switch to the BCU is either zero volts or an open circuit. Zero volts
indicates the switch is closed. An open circuit indicates that the switch is open. When the BCU sees an open circuit,
it pulls the input high internally.
The central door locking/unlocking switch has a dedicated signal input to the BCU. This allows the BCU to identify
the lock/ unlock request.
TestBook provides the ability to monitor the real time state of the central door locking/ unlocking switch.
Handset and receiver
The handset is incorporated in the key. It uses coded radio frequency signals to lock, unlock and super lock the vehicle
remotely with a range of up to 10 metres (33 ft). The handset also mobilises the vehicle by transmitting a
remobilisation signal when the handset is within range of the passive remobilisation exciter coil.
The receiver is located in front of the rear sunroof beneath the headlining. Signals transmitted by the handset are
distributed to the BCU via the receiver.
Input/Output
The BCU supplies the receiver with a 12 volts power supply. On receiving a valid signal from the handset, the receiver
transmits a 1000 baud signal to the BCU to allow locking/unlocking of the vehicle.
TestBook provides the ability to monitor the real time state of the remote receiver.

NAVIGATION SYSTEM
DESCRIPTION AND OPERATION 87-5
System Settings Menu
The system settings menu provides access to features that can be changed to suit market and personal preferences
and to navigation system operating features. On European systems, the system settings menu also includes
computer games and a currency converter. While the navigation computer is in the navigation mode, the system
settings menu can be accessed by pressing the Nav button. Using the RH rotary control, the following features can
be selected and adjusted:
lTIME – Allows the navigation system clock to be set to local time as opposed to the Greenwich Mean Time (GMT)
transmitted from the GPS satellites. The local time setting is necessary for correct navigation on routes with time
restrictions and for Estimated Time of Arrival (ETA) calculations. The time can only be adjusted in 30 minute
steps.
lSAVE POSITION– Allows the current vehicle position to be saved and allocated a name in the navigation
destination memory.
lGAMES – Provides access to a selection of computer games.
lLANGUAGE– Allows the navigation system language and voice (where applicable) to be changed.
lANIMATIONS– Allows the LCD animations to be switched on and off.
lMEASURING UNIT – Allows the route guidance distances displayed on the LCD to be switched between metric
and Imperial units.
lANNOUNCEMENT ETA – Allows the route guidance ETA announcement to be switched on and off.
lCALCULATE EURO – Provides access to a currency converter.
User Menu
The user menu provides access to further features that can be changed to suit personal preferences. While the
navigation computer is in navigation, radio or CD modes, the user menu can be accessed by pressing and holding
the tone button for more than 2 seconds. The user menu is displayed over two screens, which can be toggled between
using the

multifunction button. Using the appropriate multifunction button or the RH rotary control, the following
settings can be selected and adjusted:
Screen 1
lGal – Automatic volume control setting (see above).
lTel – If a handsfree telephone system is connected to the navigation computer, allows either mute (telephone
mute mode) or audio signal (telephone conversation via the ICE speakers) to be selected.
lLcd – The LCD can be set to appear negative, positiveor automatic. In automatic, the display will be positive or
negative, depending on the setting of the exterior lamps.
lLed – A Light Emitting Diode (LED) in the display can be set to off or blinking. When set to blinking, the LED
flashes when the navigation computer is switched off.
lM/S – Radio reception can be set to Stereo, Mono or Auto, to suppress interference and reflections and so
optimise reception. Stereo is for exceptionally good reception conditions. Mono is for poor reception conditions.
In auto, the normal setting, the navigation computer automatically switches between stereo and mono depending
on reception conditions.
Screen 2
lNav – Sets how audio navigation instructions are delivered. In onl, other audio sources are suppressed and only
the navigation instruction is output to the speakers. In mixed, the volume of any other audio source is reduced
and the volume of the navigation announcement is the same as the original audio source +/– 6 dB (adjustable).
In independ, the audio source and navigation announcement can be set to independent volume levels.
lAux – Used to switch auxiliary CD AF connections between Aux mode on and Aux mode off. If no CD
autochanger is installed, an external cassette or CD player can be connected to the navigation computer and
powered by switching on the auxiliary CD AF connections.
lCmp – Allows a compass to be shown on the LCD when route guidance is not active.
lBeV – Used to adjust the signal tone volume. Signal tones sound to confirm storage confirmation etc. and can
be set between 0 (quiet) and +5 (loud).

NAVIGATION SYSTEM
87-8 DESCRIPTION AND OPERATION
17After calibration is achieved, return to the dealership, park the vehicle and stop the engine.
18Turn the ignition switch to position I.
19Use the system settings menu to set the navigation computer to local time and the required units of measure:
aPress the Nav button.
bTurn the RH rotary control to scroll through the displayed menu, highlight TIME and press the RH rotary
control to select. Press the + or – multifunction button to adjust the time in 30 minute steps. Select the 24
hour clock and confirm by pressing the OK multifunction button.
cIf metric units of measure are required, go to step e) (the navigation computer defaults to metric units of
measure).
dIf Imperial units of measure are required, turn the RH rotary control to scroll through the displayed menu,
highlight MEASURING UNIT and press the RH rotary control to select. Turn the RH rotary control to
highlight IMPERIAL and press the RH rotary control to select.
ePress the Nav button to return to the destination menu.
20Calibration is complete. The navigation system is ready for use.
NOTE: The accuracy of the system will automatically be fine tuned when a further journey is made, but this is not
required as part of the calibration procedure.
NOTE: In European countries, the territory will have to be set the first time the navigation system is used, and the
first time a destination in another country is selected. The first time the navigation system is used or a destination
in another country is selected, a map is displayed with the default/current territory highlighted. To change the
territory: Press the RH rotary control to display the territory list; turn the RH rotary control to scroll through the
list and highlight the required territory; press the RH rotary control to confirm the selection.
A = Distance, miles (km); B = Start/Finish point
Reset
If the navigation system malfunctions, a system reset can be triggered by simultaneously pressing the TP button and
multifunction button 1 or 3. The navigation CD will need to be installed after the system reset.
