Resetting the front seat head restraints
It is necessary to reset the front seat head
restraints after the voltage supply has been
interrupted, e.g. if the battery has been
completely discharged or disconnected.
XMake sure that the cup holder on the center
console is folded down ( Y page 197).XMove the seat as far forward as possible
and the head restraint in as far as possible.
Rear seat head restraints
Important safety notes
GWarning!
For safety reasons, always drive with the rear
head restraints in the upright position when
the rear seats are occupied.
Keep the area around head restraints clear of
articles (e.g. clothing) to not obstruct the
folding operation of the head restraints.
GWarning!
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint in such a way that it
is as close to the head as possible and the
center of the head restraint supports the back
of the head at eye level. This will reduce the
potential for injury to the head and neck in the
event of an accident or similar situation.
With a rear seat occupied, make sure to move
the respective head restraint up from the
lowest non-use position and have the
occupant adjust the head restraint properly.
Do not drive the vehicle without the seat head
restraints installed when the rear seats are
occupied. Head restraints are intended to
help reduce injuries during an accident.
GWarning!
Make sure the rear seat head restraints
engage when placing them upright manually.
Otherwise their protective function cannot be
ensured.
The back of the head will not be supported in
the event of a collision. That could cause
serious or even fatal injuries. Rear seat
occupants can be seriously injured or killed.
Adjusting the head restraint heightXTo raise: pull the head restraint up until the
desired height has been reached.XTo lower: push the head restraint down
until the desired height has been reached.
Installing/removing the rear seat head
restraints
XTo remove: pull the head restraint up and
out.XTo re-install: insert the head restraint so
that the arched side points in the direction
of travel.XPush the head restraint down until you hear
it engage in position.
Adjusting the luxury head restraints
GWarning
When folding back the head restraint side
bolsters, do not put your hands between the
side bolster and the cushion holder. There is
a danger of becoming trapped.

Problems with the exterior mirrorsProblemPossible causes/consequences and M SolutionsAn exterior mirror has
been pushed out of
position.XMove the exterior mirror into the correct position manually.Automatic anti-glare mirrorsGWarning!
The auto-dimming function does not react if
incoming light is not aimed directly at sensors
in the interior rear view mirror.
The interior rear view mirror and the exterior
rear view mirror on the driver’s side do not
react, for example, when transporting cargo
which covers the rear window.
Light hitting the mirror(s) at certain angles
(incident light) could blind you. As a result,
you may not be able to observe traffic
conditions and could cause an accident.
The rear-view mirror and the exterior mirror
on the driver's side automatically go into anti-
glare mode if the ignition is switched on and
incident light from headlamps strikes the
sensor in the rear-view mirror.
The mirrors do not go into anti-glare mode if
reverse gear is engaged or the interior lighting
is switched on.

Driving systems
Cruise control
Important safety notes
Cruise control maintains a constant road
speed for you. On long and steep downhill
gradients, especially if the vehicle is laden,
you must select shift range 1, 2 or 3 in good
time. By doing so, you will make use of the
braking effect of the engine, which relieves
the load on the brake system and prevents
the brakes from overheating and wearing too
quickly.
Use cruise control only if road and traffic
conditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 20 mph
(30 km/h).
GWarning
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must always
remain responsible for the vehicle's speed
and for safe brake operation.
Only use the cruise control if the road, traffic,
and weather conditions make it advisable to
travel at a constant speed.
R The use of the cruise control can be
dangerous on winding roads or in heavy
traffic because conditions do not allow safe
driving at a constant speed.
R The use of the cruise control can be
dangerous on slippery roads. Rapid
changes in tire traction can result in wheel
spin and loss of control.
R Deactivate the cruise control when driving
in fog.
The "Resume" function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed.

GWarning
The set speed stored in memory should only
