Important!
If the electronic key is left in the starter switch
position 0 for a extended period of time, it can no longer
be turned in the lock. In this case, remove electronic key
from starter switch and reinsert.
Caution!
To prevent accelerated battery discharge and a possible
dead battery, always remove the electronic key from the
starter switch.
Do not leave the electronic key in starter
switch position 0. Notes:
A warning sounds when the driver’s door is opened
with the electronic key is in starter switch position 1
or 0.
If the electronic key cannot be turned in the starter
switch, the vehicle battery may not be sufficiently
charged. See battery on page 336 or jump starting on
page 338.
With the engine at idle speed, the charging rate of the
alternator (output) is limited.
It is therefore recommended that you turn off
unnecessary electrical consumers while driving in stop-
and-go traffic. This precaution helps to avoid draining of
the battery.
Unnecessary strain on the battery and charging system
may be minimized by turning off the following power
consumers, for example:
Heated seats, rear window defroster. In addition, the
automatic climate air volume control should be set to
the lowest position.
