Warning !

When leaving the vehicle always remove the electroni c key from the steering lock, and lock the vehicle.
Do not leave children unattended in the vehicle, or with access to an unlocked vehicle.
Unsupervised use of vehicle equipment may cause serious personal injury.


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 electron ic key from steering lock and reinsert.

Notes:
A warning sounds when the driver's door is opened with the el ectronic key 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 to 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 batte ry 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
connected.

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.
