Mirrors
Warning
G
The exterior mirrors reduce the size of the
image. Objects therefore appear further
away than they really are. You could
therefore cause an accident if you only
observe traffic in the exterior mirrors.
For this reason, you should pay attention
to traffic behind you by also using the
main exterior mirror and, if necessary, the
rear-view mirror, especially while maneu-
vering or overtaking.

iCondensation may collect under the
vehicle while Tempmatic is in opera-
tion.
Warning
G
Air flowing out of the air vents in the foot-
well when Tempmatic is in operation may
be very hot or very cold. There is therefore
a risk of frostbite or burns to bare skin in
the immediate proximity of these outlets.
Keep bare skin away from these air out-
lets. If necessary, direct the airflow into a
different area of the vehicle interior using
the air distribution control.
iIf the vehicle interior has been heat-
ed up, ventilate the vehicle before
starting your journey or briefly
switch to air-recirculation mode for
faster cooling.
Keep the air inlet on the hood free
from ice and snow.
Position the sliders for the center air
vents in the central position to pro-
vide practically draft-free ventilation.

\3 Auxiliary heating/ventilation*The auxiliary heating heats or ventilates
the interior to a temperature that you
have set. The auxiliary heating can be
operated with the engine switched on or
off.
The auxiliary heating is equipped with a
water heater.
Warning
G
Exhaust fumes are produced while the aux-
iliary heating is in operation. For this rea-
son, switch off the auxiliary heating in
enclosed spaces without an extraction sys-
tem, e.g. a garage.
Operation of the auxiliary heating system is
prohibited at gas stations or when refueling
your vehicle. The auxiliary heating must
therefore be switched off at refueling sta-
tions.
Warning
G
Observe the relevant safety regulations in
the case of vehicles used for the transport
of hazardous goods.
Aerosols, gas cartridges and other pressur-
ized containers transported in the vehicle
may be highly flammable and could explode
when heated.
Make sure that the containers described
are kept away from the flow of hot air from
the auxiliary heating.
Otherwise, you could endanger yourself
and others.
