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). Seats
Important safety notes
G
WARNING
You could lose control of your vehicle if you do the following while driving:
R adjust the driver's seat, head restraint,
steering wheel or mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt before starting the engine. G
WARNING
If the driver's seat is not engaged, it could
move unexpectedly while the vehicle is in
motion. This could cause you to lose control of the vehicle. There is a risk of an accident.
Always make sure that the driver's seat is
engaged before starting the engine. G
WARNING
When you adjust a seat, you or other vehicle
occupants could become trapped, e.g. on the seat guide rail. There is a risk of injury.
Make sure when adjusting a seat that no one
has any body parts in the sweep of the seat. G
WARNING
The seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seat belt is routed
across the center of your shoulder. G
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.
Your seat must be adjusted in such a way that you can wear the seat belt correctly.
Observe the following points:
R Position the backrest in an almost vertical
position so that you are sitting virtually
upright. Do not drive with the backrest
reclined too far back.
R Your arms should be slightly bent when you
are holding the steering wheel.
R Avoid seat positions that prevent the seat
belt from being routed correctly. The shoul-
der section of the belt must be routed over the middle of your shoulder and be pulled
tight against your upper body. The lap belt
must always pass across your lap as low
down as possible, i.e. over your hip joints. 82

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

Read the information on qualified specialist
workshops (Y page 25). Overview of climate control systems
Important safety notes
Observe the recommended settings on the
following pages. Otherwise, the windows
could fog up.
Climate control regulates the temperature
and the humidity in the vehicle interior and
filters undesirable substances from the air.
Climate control is only operational when the
engine is running. The system only functions
optimally when the side windows are closed.
i Ventilate the vehicle for a brief period
during warm weather. In order to cool the
vehicle more rapidly, switch climate control
to air-recirculation mode briefly. This will
speed up the cooling process and the
desired vehicle interior temperature will be reached more quickly.
i The integrated filter can filter out most
particles of dust and completely filters out
pollen. A clogged filter reduces the airflow
into the vehicle interior. For this reason,
you should always observe the interval for
replacing the filter, which is specified in the Maintenance Booklet. As it depends on
environmental conditions, e.g. heavy air
pollution, the interval may be shorter than
that stated in the Maintenance Booklet. 112

switched off prematurely or cannot be acti-
vated.
X Switch off any consumers that are not
required, e.g. reading lamps or interior
lighting.
If enough on-board voltage is available again
within 30 seconds, the rear window heating
automatically switches on again. It otherwise
remains switched off. Switching air-recirculation mode
on/off
Important safety notes When you switch on air-recirculation mode,
the windows could fog up more quickly, in
particular at low outside temperatures. Only
switch on air-recirculation mode for a short
time.
You can deactivate the intake of fresh air if
unpleasant odors enter the vehicle from out-
side. The air inside the vehicle will only be
circulated.
Heating/air-conditioning system Air-recirculation mode switches off automat-
ically after about 10 to 30 minutes, depending
on the outside temperature.
X Switch on climate control (Y page 116).
X To switch on/off: press the008Aswitch.
If the indicator lamp in the 008Abutton
lights up, air-recirculation mode is activa-
ted.
Rear-compartment heating/rear-com-
partment air conditioning On vehicles with a rear-compartment heating
and air-conditioning system, you can acti-
vate/deactivate air-recirculation mode for
the rear-compartment climate control.
X Switch on climate control (Y page 116).
X To activate: set the temperature control of
rear-compartment heating 0087(Ypage 115) or rear-compartment air conditioning sys-
tem
0044(Ypage 116) to the center position.
Only one of the two climate control sys-
tems in the rear compartment is activated
and is in air-recirculation mode.
X To deactivate: turn the temperature con-
trol of rear-compartment heating 0087
(Y page 115) or rear-compartment air-con-
ditioning system 0044(Ypage 116) clock-
wise or counterclockwise. Only change the
temperature in small increments. Adjusting the air vents
Important safety notes
G
WARNING
Very hot or very cold air can flow from the air vents. This could result in burns or frostbite in the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior.
The center and side air vents are adjustable.
On vehicles with a rear-compartment air-con-
ditioning system, you can also adjust the air
vents in the roof duct.
i For virtually draft-free ventilation, adjust
the sliders of the center air vents to the
center position.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior, please observe the following notes:
R keep the air inlet grille on the hood free of
blockages, such as ice, snow or leaves.
R never cover the vents or the ventilation
grilles in the vehicle interior. 120
