consumer, e.g. the heated rear window to com-
pensate the voltage peak caused by disconnect-

charge in the battery.
Glow Mode
In cold weather, the glow plugs in most diesel vehicles
will be preheated electrically. This is indicated by the
GLOW indicator on dashboard. The process needs a
current of 40
– 60 Amp and takes about 4 – 6 seconds.
1. In this case, after the jump starter is fully recharged
and connected, press the GLOW button (5).
2. Start the engine after preheating.
