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 26). Seats
Important safety notes
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 arisk of injury.
Make sure when adjusting aseat that no one
has any body parts in the sweep of the seat. G
WARNING
If head restraints are not installed and
adjusted 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
installed. 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. Observe also the safety notes in the sections
on "Air bags" (Y
page 44) and "Children in the
vehicle" ( Ypage 50).
Do not change over the head restraints for the
fron tand rea rseats. Otherwise, it will not be
possible to correctly adjust the height and
angle of the head restraints.
Use the head restraint pad to adjust the head
restraint so that it is as close as possible to
the back of your head.
Before the journey, make sure the head
restraints have been correctly set for each of
the vehicle's passengers (Y page 84). Driver's and co-driver's seat

Read the information on qualified specialist

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
countries. Lamp failure indicator
The bulb failure indicator is only an aid. You
are responsible for the proper functioning of
the vehicle lighting. Insufficient or non-
functioning vehicle lightin gputs the operating
safety of the vehicle at risk.
For this reason, check the condition and
function of your vehicle's lighting system and,
if necessary, that of the trailer before each
journey.
The bulb failure indicator monitors all of the
exterio rlighting lamps, except the perimeter
lamp and the trailer lighting. If a bulb fails,
either the 0002(Ypage 34) indicator lamp
lights up, or you will see a corresponding
message in the display (Y page 201).
i Depending on the equipment, the bulb
failure indicator can fail for all lamps with
the exceptio nofthe turn signal lamps. Light switch

Read the information on qualified specialist
workshops (Y page 26). 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. Aclogged 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
stated in the Maintenance Booklet. 108

Rear window defroster
Rear window defroste
rswitch
The rear window defroster consumes a lot of
power. You should therefore switch it off as
soon as the window is clear .The rear window
defroster otherwise switches off
automatically after 12 minutes.
X Start the engine.
X To switch on/off: press the0019switch.
The indicator lamp in the 0019button
comes on when the rear window defroster
is switched on.
If the indicator lamp in the 0019rear window
defroster button flashes, the on-board
voltage is too low. The rear window defroster
has switched off prematurely or cannot be
activated.
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 defroster
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
outside. The air inside the vehicle will only be
circulated.
Heating/air-conditioning system
Air-recirculation mode switches off
automatically after about 10to 30 minutes,
depending on the outside temperature.
X
Switch on climate control (Y page 112).
X To switch on/off: press the0022switch.
If the indicator lamp in the 0022button
lights up, air-recirculation mode is
activated.
Rear-compartment heating/rear-
compartment air conditioning On vehicles with a rear-compartment heating
and air-conditioning system, you can
activate/deactivate air-recirculation mode
for the rear-compartment climate control.
X Switch on climate control (Y page 112).
X To activate: set the temperature control of
rear-compartment heating
0026(Y page 111) or rear-compartment air
conditioning system 0006(Ypage 112) to the
center position.
Only one of the two climate control
systems in the rear compartment is
activated and is in air-recirculation mode.
X To deactivate: turn the temperature
control of rear-compartment heating
0026(Y page 111) or rear-compartment air-
conditioning system 0006(Ypage 112)
clockwise or counterclockwise. Only
change the temperature in small
