with button &).
R Always carry the SmartKey with you.
R Never store the SmartKey together with
-electronic

items such as a mobile phone
or another SmartKey
- metallic objects such as coins or metal

Safety notes
G
Warning!
In order to avoid possible loss of vehicle
control the following must be done before the
vehicle is put into motion:
R seat adjustment
R head restraint adjustment
R steering wheel adjustment
R rear view mirror adjustment
R fastening of seat belts G
Warning!
Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position as
this can be dangerous. You could slide under
the seat belt in a collision. If you slide under
it, the seat belt would apply force at the
abdomen or neck. That could cause serious
or fatal injuries. The seat backrest and seat
belts provide the best restraint when the
wearer is in a position that is as upright as
possible and seat belts are properly
positioned on the body. G
Warning!
Your seat must be adjusted so that you can
correctly fasten your seat belt. Seats

Easy-entry/exit feature
This feature allows the driver an easier entry
into and exit from the vehicle. When entering
and exiting the vehicle, the steering wheel is
in its uppermost position.
The easy-entry/exit feature can be activated
or deactivated in the Convenience submenu
of the control system (Y page 124). G
Warning!
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 one
of the memory position buttons.
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.
With the easy-entry/exit feature activated,
the steering wheel will return to its last set
position when you close the driver’s door with
the ignition switched on. The steering wheel
will also return to its last set position when
you insert the SmartKey into the starter
switch or press the KEYLESS-GO start/stop
button once with the driver’s door closed.
i The last set steering wheel position is
stored when the ignition is switched off or
the position is stored in memory
(Y page 86).
With the easy-entry/exit feature activated,
the steering wheel tilts upwards when you
remove the SmartKey from the starter switch.
The steering wheel also tilts upwards when
you open the driver’s door with the SmartKey in starter switch position
0 or 1 or the
KEYLESS-GO start/stop button in position 1.
i When the current position for the steering
wheel is in the uppermost tilt position, the
steering wheel will no longer be able to
move upward when the easy-entry/exit
feature is activated.
The adjustment procedure is briefly
interrupted when the engine is started. G
Warning!
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.
Crash-responsive exit aid When you open the driver’s door after an
accident has occurred, the steering column
moves up. The position of the SmartKey in the
starter switch is insignificant. This function
facilitates exiting as well as rescue of vehicle
