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.
Notes:
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.
