Adjust the head restraint so that it supports
the back of the head at eye level.
R The distance from the pedals should be
such that you can depress them fully.
Observe also the safety notes in the section
on "Air bags" (Y page 47)and "Children in the
vehicle" (Y page 51).
If you swap over the head restraints for the

WARNING
If the driver's and co-driver's seats are not
engaged facing the direction of travel while
driving, the restraint systems may not be able to provide the intended protection. There is an
increased risk of injury, possibly even fatal.
Engage the driver's and co-driver's seats so
they are facing the direction of travel before
starting the engine.
! When rotating the seats, make sure that
there is sufficient space to do so.
Move the seat forward or back first. This
will help to avoid contact with other parts of
the interior.
Push the handbrake lever down to the stop.
The parking brake or handbrake lever could
otherwise be damaged. Seat release (example: co-driver's seat)
The driver's seat and co-driver's seat can be
rotated by 50° and 180°.
The seats engage when facing in the direction of travel as well as when facing in the oppositedirection and also engage at an angle of 50°
to the door.
X Make sure that the parking brake has been
engaged and that the handbrake lever has
been pushed down to the stop
(Y page 150).
X Adjust the steering wheel to provide the
necessary space to rotate and adjust the
driver's seat (Y page 88).
X Before rotating, push the co-driver's seat

WARNING
If head restraints are not installed and adjus-
ted correctly, they cannot provide protection
as intended. There is an increased risk of
injury in the head and neck area, e.g. in the
event of an accident or when braking.
Always drive with the head restraints instal-
led. Before driving off, make sure for every
vehicle occupant that the center of the head
restraint supports the back of the head at
about eye level.
Do not change over the head restraints for the
front and rear seats. Otherwise, it will not be
possible to correctly adjust the height and
angle of the head restraints.
Adjust the head restraint so that it is as close as possible to your head. Head restraint (example: luxury head restraint on

Useful information
This Operator's Manual describes all models
as well as standard and optional equipment of your vehicle that were available at the time of going to print. Country-specific variations are
possible. Note that your vehicle may not be
equipped with all of the described functions.
This also applies to systems and functions
relevant to safety.
Read the information on qualified specialist
workshops (Y page 25). Exterior lighting
Important safety notes
For reasons of safety, we recommend that
you drive with the lights switched on even
during the daytime. There may be differences
in operation due to legal requirements and
voluntary recommendations in some coun-
tries. Bulb failure indicator
The bulb failure indicator is only an aid. You
are responsible for the proper functioning of
the vehicle lighting. Insufficient or non-func-
tioning vehicle lighting puts the operating
safety of the vehicle at risk.
For this reason, check the condition and func-
tion of your vehicle's lighting system and, if
necessary, that of the trailer before each jour- ney.
The bulb failure indicator monitors all of the
exterior lighting lamps, except the perimeter
lamp and the trailer lighting. If a bulb fails,
either the 0049(Ypage 35) indicator lamp
lights up, or you will see a corresponding
message in the display (Y page 208).
i Depending on the equipment, the bulb
failure indicator can fail for all lamps with
the exception of the turn signal lamps. Light switch

Automatic headlamp mode G
WARNING
When the light switch is set to 0058, the low-
beam headlamps may not be switched on
automatically if there is fog, snow or other
causes of poor visibility due to the weather
conditions such as spray. There is a risk of an
accident.
In such situations, turn the light switch to
0058.
Automatic headlamp mode is only a driving
aid. You are responsible for the vehicle light-
ing at all times.
Depending on ambient light, the rain and light sensor automatically switches on the parking lamps, low-beam headlamps and the license
plate lamp. This excludes weather-related
impairments to visibility, such as snow, fog or
spray.
If there is fog, snow or spray, turn the light
switch quickly from 0058to0058. You could
otherwise briefly interrupt operation of the
headlamps.
X To switch on automatic headlamp
mode: turn the light switch to 0058.
Key in position 1in the ignition lock: the
parking lamps switch on or off automati-
cally depending on the ambient light.
When the engine is running: if you activate
the "daytime running lamps" function using the on-board computer, the daytime run-
ning lamps are switched on. The parking
lamps and low-beam headlamps also
switch on or off automatically, depending
on the ambient light.
When the low-beam headlamps are
switched on, the 0058indicator lamp in the
instrument cluster lights up.
Fog lamps/rear fog lamp G
WARNING
If you suspect that driving conditions will be
foggy, turn the light switch to 0058before you
start your journey. Your vehicle may other-
wise not be visible and you could endanger
yourself and others. G
WARNING
In low ambient lighting or foggy conditions,
only switch from position 0058to0058 with
the vehicle at a standstill in a safe location.
Switching from 0058to0058 will briefly
switch off the headlamps. Doing so while driv-
ing in low ambient lighting conditions may
result in an accident.
