switch off automatically. 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
the ignition lock or in position 1.
The steering wheel is moved automatically to
the position previously set when the key is
inserted into the ignition lock with the driver's
door closed. G
Risk of injury
Make sure that nobody can become trap-
ped when you activate the easy-entry/exit
feature.
If there is a risk of becoming trapped, stop
the adjustment procedure. To halt the pro-
cedure:
R press the steering-column adjustment
switch
R press one of the memory function posi-
tion buttons
The steering column stops moving immedi-
ately. Never leave children unsupervised in the
vehicle. 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 92).
You can activate and deactivate the easy-
entry/exit feature via the on-board computer
(Y page 135). Controls

Selecting the switch-on time for the
auxiliary heating* This function is only available if the vehicle
has an auxiliary heating system.
The
Auxiliary heating function allows you
to select three switch-on times. You can set
the exact switch-on time using the other func-
tions in the Heatersubmenu.
You can switch off the auxiliary heating by
using the remote control or the auxiliary heat-
ing button on the centre console.
The auxiliary heating is switched off automat-
ically after 50 minutes. This time can be
changed. To do this, visit a qualified specialist
workshop, e.g. a Mercedes-Benz Service
Centre. G
Risk of poisoning
Exhaust fumes are produced when the aux-
iliary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You
should therefore switch off the auxiliary heating in confined spaces without an
extraction system, e.g. a garage.
G
Risk of fire
When operating the auxiliary heating, parts
of the vehicle may become very hot, and
highly inflammable material such as fuels
could be ignited. Operating the auxiliary
heating is thus prohibited at filling stations
or when your vehicle is being refuelled. You
must therefore switch off the auxiliary heat-
ing at filling stations.
You can call up the Auxiliary heating.
