A warning sounds when the driver’s door is opened 
while the key is in steering lock position 1 or 0.
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.Caution!
To prevent accelerated battery discharge and a possible 
dead battery, always remove the key from the steering 
lock. Do not leave the key in steering lock position 0.
