Warning
G
The exterior mirrors reduce the size of the
image. Objects therefore appear further
away than they really are. You could there-
fore 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 ex-
terior mirror and, if necessary, the rear-view
mirror, especially while maneuvering or
overtaking.

Tempmatic is only operational while the
engine is running. You can use Tempmatic
to regulate or control the temperature au-
tomatically. The vehicle is either heated or
cooled, depending on the temperature se-
lected and the outside temperature.
The combination filter removes most dust
particles, pollen and unpleasant odors
from the outside air.
The interval for replacing the filter depends
on environmental factors, e.g. high air pol-
lution. The interval may be shorter than
that indicated in the Service Booklet.

Follow the settings recommended on the
following pages for heating or cooling. The
windows could otherwise fog up. As a result,
you could be distracted from road and traffic
conditions and cause an accident.Warning
G
Air flowing out of the air vents in the footwell
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 imme-
diate proximity of these outlets. Keep bare
skin away from these air outlets. If neces-
sary, direct the airflow into a different area
of the vehicle interior using the air distribu-
tion control.

Auxiliary heating/ventilation*
3
\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.
The auxiliary heating heats the coolant and
the vehicle interior and is therefore more
favorable to the engine and consumes less
fuel. The fuel tank must be at least a quar-
ter full to ensure that the auxiliary heating/
ventilation operates correctly.
The maximum heating period is
60 minutes.You can use the auxiliary heating / ventila-
tion to:
\4ventilate or preheat the vehicle interior
and to de-ice the windows
\4start the engine better in cold weather
\4support the vehicle’s heating system
while the engine is running and outside
temperatures are low (heater booster
function) (\2page 137)
You can use the operating system to define
up to three switch-on times, one of which
can be selected to switch on the auxiliary
heating / ventilation (\2page 142). Warning
G
Exhaust fumes are produced while the auxilia-
ry heating is in operation. For this reason,
switch off the auxiliary heating in enclosed
spaces without an extraction system, e.g. a
garage.
Operation of the auxiliary heating system is
prohibited at gas stations or when refueling
your vehicle. The auxiliary heating must there-
fore be switched off at refueling stations.
Warning
G
Observe the relevant safety regulations in the
case of vehicles used for the transport of haz-
ardous 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.
iThe auxiliary heating automatically
switches to heater booster mode after
the engine is started.

as you close the sliding sunroof.
The glass may shatter in the event of an ac-
cident.
If you or other occupants are not wearing
your seat belt, there is a risk of being thrown
out of the opening in the event of the vehicle
overturning. Therefore, always wear a seat
belt to reduce the risk of injuries.
In accidents in which the vehicle overturns,
there is an increased risk of injury even for
occupants who have fastened their seat
belts correctly, as their head or limbs could
be thrust through the opening.
Remove the key from the ignition lock even
if you are only leaving the vehicle for a short
time.
!
CAUTION
Do not raise the sliding sunroof if you
have mounted a roof rack. It would oth-
erwise strike the roof rack.
You could thereby damage the sliding
sunroof and the roof rack.
iThe sliding sunroof opens automatical-
ly when you press the sliding sunroof
switch for opening beyond the pressure
point and then release it.
To stop the sliding sunroof, press the
sliding sunroof switch again in any di-
rection.!
CAUTION
Do not transport objects protruding
through the sliding sunroof. You could
otherwise damage the sliding sunroof.

Driving systems

\3 Driving systemsDriving systems which may form part of
your vehicle are described on the following
pages:
\4Cruise control* (\2page 147), which
you can use to control the speed of
your vehicle
\4Parktronic system*, which is an aid for
parking and maneuvering
(\2page 150)
\4Reverse warning feature*, which helps
you ensure the safety of other road us-
ers (\2page 153)
The ABS, BAS, ESP
®, ASR and EBV driving
safety systems are described in the "Safe-
ty and Security" section (\2page 23).Cruise control maintains the speed of the
vehicle for you.
Use cruise control if road and traffic condi-
tions make it appropriate to maintain a
steady speed for a prolonged period. You
can store any road speed above 20 mph
(30 km/h).
Cruise control*iThe increments for setting speed and
the threshold values for switching on or
automatically switching off cruise con-
trol depend on the digital speedometer
setting, mph or km/h (\2page 99).Warning
G
The cruise control function cannot take ac-
count of road and traffic conditions.
Always pay attention to road and traffic
conditions, even when cruise control is acti-
vated.
Cruise control is only an aid designed to as-
sist driving. You are responsible for the vehi-
cle’s speed and for braking in good time.
If there is a change of drivers, advise the
new driver of the cruising speed that is
stored.Warning
G
Do not use cruise control:
\4if road and traffic conditions do not per-
mit a constant driving speed to be main-
tained (e.g. heavy traffic or winding
roads). You could otherwise cause an
accident.
\4on slippery roads. The drive wheels may
lose their grip when braking or acceler-
ating and the vehicle could skid
