ion battery: if the indicator/warning lamps in
the instrument cluster do not light up at low
temperatures, it is very likely that the dis-
charged battery has frozen .Inthis case you may
neither jump-start the vehicle nor charge the
battery. The service life of abattery that has
been thawed may be reduced. The starting char-
acteristics may be impaired, especially at low
temperatures. Have the thawed battery
checked at aqualified specialist workshop. Vehicles with
alithium-ion battery: at low
temperatures, do not charge abattery which has
been removed using abattery charger. Allow the
battery to warm up gently first, if necessary.
Otherwise, the service life can be shortened and the starting characteristics impaired, especially
at low temperatures. 344
