cluster displayPractical hints Car care Index Important!
If the electronic key is left in the steering lock position 0
for an extended period of time, it can no longer be
turned in the lock. In this case, remove electronic key
from steering lock and reinsert.
Caution!
To prevent accelerated battery discharge and a possible
dead battery, always remove the electronic key from the
steering lock. Do not leave the electronic key in steering
lock position 0.Notes:
A warning sounds when the driver’s door is opened
while the electronic key is in steering lock position 1
or 0.
If the electronic key cannot be turned in the steering
lock, the vehicle battery may not be sufficiently charged.
See battery on page 270 or jump starting on page 271.
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 traf fic. 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.
The steering lock can only be unlocked with the vehicle
battery properly charged and connected.
