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.

TIRE PRESSURE MONITORING SYSTEM
(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.
NOTE
It is the responsibility of the driver to react
promptly and with discretion to alerts and
warnings. Abnormal tire inflation pressures
should be corrected at the earliest 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 correspond
to a parameter range defined as unavailable,
then the reading is considered as not available
and appears as two dash lines “_ _“.
