GWarning!
You must make sure no one can become
trapped or injured by the moving steering
wheel when the easy-entry/exit feature is
activated.
To stop steering wheel movement, move
steering wheel adjustment stalk or press the
memory position switch.
Do not leave children unattended in the
vehicle, or with access to an unlocked vehicle.
Children could open the driver's door and
unintentionally activate the easy-entry/exit
feature, which could result in an accident
and/or serious personal injury.
The EASY-ENTRY/EXIT feature makes getting
in and out of your vehicle easier.
The steering wheel swings upwards when
you:
R remove the key from the ignition lock.
R open the driver's door and KEYLESS-GO is
in position 1
R open the driver's door and the key is in
position 0 or 1 in the ignition lock.
i The steering wheel only moves upwards if
it has not already reached the upper end
stop.
The steering wheel is moved to the last
selected position when:
R the driver's door is closed, and
R you insert the key into the ignition lock.
or
R in vehicles with KEYLESS-GO, you press the
Start/Stop button once.
When you close the driver's door with the
ignition switched on, the steering wheel is
also automatically moved to the previously
set position.
The last position of the steering wheel is
stored when you switch off the ignition or
when you store the setting with the memory
function ( Y page 102).
You can activate and deactivate the EASY-
ENTRY/EXIT feature in the on-board
computer ( Y page 181).GWarning
Let the system complete the adjustment
procedure before setting the vehicle in
motion. All steering wheel adjustment must
be completed before setting the vehicle in
motion. Driving off with the steering wheel
still adjusting could cause the driver to lose
control of the vehicle.
i If the crash-responsive EASY-EXIT feature
is triggered in an accident, the steering
column will move upwards when the
driver's door is opened. This occurs
irrespective of the position of the key in the
ignition lock. This makes it easier to exit the
