Battery Charge Indicator Lamp
When the key is in position 2 in the ignition lock, the
battery charge indicator lamp # will light up in the
instrument cluster. It must go out when the engine is
running.
If the battery charge indicator lamp # remains on or
lights up again while the vehicle is moving, a fault has
developed in the battery charge circuit.
Do not drive on. Take your vehicle to an authorized
Sprinter Dealer to have the problem corrected.
Water in Fuel Indicator Lamp
When the key is turned to position 2 in the ignition
lock, the fuel filter indicator lamp
in the
instrument cluster lights up for about 2 seconds. It
must go out when the engine is running.
If water in fuel indicator lamp does not go out or
comes on with the engine running, drain the water
from the fuel filter as soon as possible.
