SELF-DIAGNOSTIC AT START-UP
Initiate the self-diagnostic as follows:

The engine must be running since at least
15 seconds with parking brake applied.

Trip the CRUISE rocker switch located on
the lateral control panel from OFF to ON
position.
The following sequence will begin:
1. Pop-up message "Impact Alert" will show in
the DID;
2. The speedometer LEDs will flash in red;
3. FORWARD VEHICLE DETECTED telltale
will flash in red;
4. The Impact Alert audible alarm will sound.
At the end of the self-diagnostic sequence, pop-
up message « ACB SELF CHECK OK » will
show on the DID if the system functions properly
or « ACB SELF CHECK NOT OK » if a fault
condition is detected.

SYSTEM MALFUNCTION

In case of system malfunction, visual warnings
will illuminate in the instrument cluster or the
driver information display to warn the driver that
the ACB is disabled. In that situation, the Impact
Alert and Distance Alert functions are not
available.
If the ACB is not available, the FORWARD
VEHICLE DETECTED telltale light will illuminate
in red and will stay on and "ACB NOT
AVAILABLE" pictogram will appear on the DID
status line.

For proper functioning of the system, the radar
must be perfectly aligned and not blocked. If a
radar fault condition is detected, one of the
following pop-up messages will show in the DID.
ACB RADAR MISALIGNMENT
ACB RADAR FAULT
ACB RADAR DATA LINK FAILURE
ACB RADAR BLOCKED
TIRE
(TPMS)
This system is a sensing device designed to
identify and display tire operating data and
activate an alert or warning when pressure or
temperature irregularities are detected.

It is the responsibility of the driver to react
promptly and with discretion to alerts and
warnings. Abnormal tire inflation pressures
should
opportunity.

TPMS DISPLAY

TPMS Display
The TPMS display knows where the sensors are
located. It receives the raw temperature and
pressure readings from the TPMS receiver, it
reads several signals from the vehicle and does
the calculation required to generate the various
screens.
When no readings have been received for a tire
location or when the received data corresponds
to a parameter range defined as unavailable,
then the reading is considered as not available
and appears as two dash lines "_ _".
