Points to remember
Depending on the vehicle equipment, you can
adjust the steering wheel either manually or
electrically*. G
Risk of injury
The electrically adjustable steering wheel*
can be adjusted when the key is removed
from the ignition lock. Therefore, do not leave
children unsupervised in the vehicle as they
could become trapped as the steering wheel
is adjusted. G
Risk of accident
Only adjust the steering wheel when the vehi-
cle is stationary and do not pull away until the
steering wheel adjustment mechanism is
locked in position. Otherwise, you might drive
without the steering wheel adjustment mech-
anism being locked in position and be distrac-
ted from road and traffic conditions by an
unexpected movement of the steering wheel
and cause an accident. 70

Easy-entry/exit feature*
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 when the key is in
position 0or 1in the ignition lock
When the key is inserted into the ignition lock
with the driver's door closed, the steering
wheel is automatically moved to the previ-
ously set position. G
Risk of injury
Make sure that nobody can become trapped
when you activate the easy-entry/exit fea-
ture.
If there is a risk of becoming trapped, stop the
adjustment procedure. To halt the procedure:
R press the steering-column adjustment
switch
R press one of the memory function position
buttons
The steering column stops moving immedi-
ately.
Never leave children unsupervised in the vehi-
cle. They could open the driver's door and
thereby unintentionally activate the easy-
entry feature and become trapped.
The most recent position of the steering
wheel is stored when you switch off the igni-
tion or when you store a memory position
(Y page 74).
You can activate and deactivate the EASY-
ENTRY/EXIT feature via the on-board com-
puter (Y page 108).
i The crash-responsive EASY-EXIT fea-
ture* can only be activated after an acci-
dent if the EASY-ENTRY/EXIT feature is
activated in the on-board computer.
When the crash-responsive EASY-EXIT fea-
ture is triggered in an accident, the steering
wheel column will move upwards irrespec- tive of the position of the key in the ignition
lock. This makes it easier to exit the vehicle
or rescue the occupants. Mirrors

detect all obstacles. It is not a substitute for
attentive driving.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. You could otherwise endanger
yourself and others. G
Risk of injury
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.

using ultrasound. It indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is activated automatically when
you:
R switch on the ignition
R release the parking brake
R shift the automatic transmission to D,Ror
N
PARKTRONIC is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
PARKTRONIC monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper. :
Example: sensors in the front bumper,
