instrument panel display or as
warning and signal buzzers. Check
control messages appear on the
Info-Display. Some appear in an
abbreviated form. Confirm warning
messages with the multifunction
control 3 86.
Warning chimes When starting the engine or
whilst driving ■ If seat belt is not fastened.
■ If a door or the tailgate is not fully closed when starting-off.
■ If a certain speed is exceeded with the parking brake applied.
■ If the speed programmed at the factory is exceeded.
■ If the vehicle has manual transmission automated and the
driver's door is opened when theengine is running, a gear is
engaged and the foot brake is not
depressed.
■ Warning signal sounds three times if the rear carrier system is
extended and reverse gear is
selected.
When the vehicle is parked and
the driver's door is opened ■ When the key is in the ignition switch.
■ With exterior lights on.
■ For manual transmission automated, if the parking brake is
not applied and no gear is engaged when the engine is switched off.
During an Autostop ■ If the driver's door is opened.
Battery voltage Low battery voltage in the radio
remote control. On vehicles without
check control, the message InSP3
appears in the instrument panel
display. Replace the battery 3 20.Brake light switch
Brake light does not come on during
braking. Have the cause of the fault
remedied immediately by a
workshop.
Drain diesel fuel filter
If there is water in the diesel fuel filter, the message InSP4 appears in the
instrument panel. In some models
InSP4 illuminates together with A in
the instrument. Consult a workshop.
Lighting
Important exterior lighting lamps,
including cables and fuses, are
monitored. In trailer mode, trailer
lighting is also monitored. Trailers
with LED lighting must have an
adapter that enables lamp monitoring as with conventional bulbs.

switches between daytime running
light and low beam depending on
external lighting conditions.

visibility of the vehicle during daylight.
Tail lights are not on.
Automatic low beam activation
During poor lighting conditions the
low beam is switched on.
Tunnel detection
When a tunnel is entered the low
beam is switched on.

Stop-start system 3 116.Air conditioning system
In addition to the heating and
ventilation system, the air
conditioning system has:
n=cooling4=air recirculation
Heated seats ß 3 38, Heated
steering wheel * 3 71.
Cooling n
Press button n to switch on cooling.
Activation is indicated by the LED in
the button. Cooling is only functional
when the engine is running and
climate control fan is switched on.
Press button n again to switch off
cooling.
The air conditioning system cools and
dehumidifies (dries) as soon as the
outside temperature is slightly above
the freezing point. Therefore
condensation may form and drip from
under the vehicle.
If no cooling or drying is required,
switch off the cooling system for fuel
saving reasons. Activated cooling
might inhibit Autostops.
Notice
If the climate control is set to
maximal cooling while the ambient
temperature is high, an Autostop
may be inhibited until the requested
temperature in the passenger
compartment has been reached.
If the climate control is set to
maximal cooling while the engine is
in an Autostop, the engine may
restart automatically.

Air recirculation system 4
The air recirculation mode is operated with the 4 button.9Warning
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling the air humidity increases, so the
windows may mist up from inside.
The quality of the passenger
compartment air deteriorates,
which may cause the vehicle
occupants to feel drowsy.
Air distribution to l: Air recirculation
is deactivated.
In warm and very humid ambient air conditions, the windscreen might mist up from outside, when cold air is
directed to it. If windscreen mists up
from outside, activate windscreen
wiper and deactivate s.
Maximum cooling
Briefly open the windows so that hot air can disperse quickly.
