To bear in mind
Before the breath test
In order to obtain correct function and as accu-
rate a measurement result as possible:
•
Avoid eating or drinking approx.
5 minutes before the breath test.
•
Avoid excess windscreen washing - the
alcohol in the washer fluid may result in an
incorrect measurement result.
Change of driver
In order to ensure that a new breath test is car-
ried out in the event of a change of driver -
depress the switch (2) and the send button (3)
simultaneously for approx. 3 seconds. At
which point the car returns to start inhibition
mode and a new approved breath test is
required before starting the engine.
Calibration and service
The Alcolock must be checked and calibrated
at a workshop
2
every 12 months.
30 days before recalibration is necessary the
display shows
ALCOGUARD CALIBR.
REQUIRED
. If calibration is not carried out
within these 30 days then normal engine star-
ting will be blocked - only starting with the
Bypass function will then be possible, see
page 148 section Emergency situation.
The message can be cleared by pressing the
send button (3) once. Otherwise it goes out on
its own after approx. 2 minutes but then reap-
pears each time the engine is started - only
recalibration at a workshop
2
can clear the mes-
sage permanently.
Cold or hot weather
The colder the weather the longer it takes
before the Alcolock is ready for use:
Temperature (ºC) Maximum heat-
ing time (sec-
onds)
+10 to +85 10
-5 to +10 60
-40 to -5 180
At temperatures below -20 ºC or above
+60 ºC the Alcolock requires additional power
supply. The display shows
ALCOGUARD
INSERT POWER CABLE
. In which case, con-
nect the power supply cable from the glovebox
and wait until indicator lamp (6) is green.
In extremely cold weather the heating time can
be reduced by taking the Alcolock indoors.
Emergency situation
In the event of an emergency situation or the
Alcolock is out of order, it is possible to bypass
the Alcolock in order to drive the car.
NOTE
All Bypass activation is logged and saved in
memory, see page 10 in the section,
Recording data.
After the Bypass function has been activated
the display shows
ALCOGUARD BYPASS
ENABLED
the whole time while driving and
can only be reset by a workshop
2
.
The Bypass function can be tested without the
error message being logged - in which case,
carry out all the steps without starting the car.
The error message is cleared when the car is
locked.
When the Alcolock is installed, either the
Bypass or Emergency function is selected as
the bypassing option. This setting can be
changed afterwards at a workshop
2
.

An authorised Volvo workshop is recommended.
