Location of the batteries
A: Left-hand drive car. B: Right-hand drive car.
(1) Starter battery
14
(2) Support battery.
The support battery normally requires no
more service than the normal battery used for
starting. A workshop should be contacted in
the event of questions or problems - an
authorised Volvo workshop is recommended.
IMPORTANT
If the following instruction is not observed
then the Start/Stop function may tempo-
rarily cease to work after the connection of
an external battery or battery charger:
•
The negative battery terminal on the
car's starter battery must never be
used for connecting an external bat-
tery or battery charger - only the car
chassis may be used as the ground-
ing point.
See Jump starting with battery (p. 270) for
a description of how the cable clamps
must be attached.
NOTE
If the battery has become so discharged
that everything is "black" and in principle
the car does not have all the normal elec-
trical functions and the engine is subse-
quently started using an external battery or
battery charger, then the Start/Stop func-
tion will be activated. It will then be possi-
ble for the engine to be auto-stopped but
in the event of an auto-stop the Start/Stop
function may fail to auto-start the engine
due to inadequate capacity in the battery.
The battery must first be charged in order
to ensure a successful auto-start after an
auto-stop. At an outside temperature of
+15 °C the battery needs to be charged for
at least 1 hour. At a lower outside tem-
perature a charging time of 3-4 hours is
recommended. The recommendation is
that the battery is charged using an exter-
nal battery charger.
If this is not possible then the recommen-
dation is to temporarily deactivate the
Start/Stop function until the battery has
been adequately recharged.
For more information on charging the
starter battery, see Battery (p. 361).
