& WARNING Risk of explosion from a frozen
battery
A discharged battery may freeze at tempera-
tures slightly above or below freezing point.
During starting assistance or battery charging,
battery gas can be released.
Always allow a battery to thaw before
#
charging it or performing starting assis-
tance.
If the indicator/warning lamps on the instrument
cluster do not light up at low temperatures, it is
very likely that the discharged battery has frozen.
In this case, you may neither jump-start the vehi-
cle nor charge the battery.
The service life of a battery that has been thawed
may be dramatically shortened. The starting char-
acteristics may be impaired, especially at low
temperatures.
It is recommended that you have a thawed battery
checked at a qualified specialist workshop.
All vehicles
