Thermotronic multi-zone luxury automatic climate control*
Front control unit
Rear control panel* Thermotronic multi-zone luxury automatic
climate control combines an automatic heat-
ing and ventilation system with a cooling sys-
tem. The temperature and air distribution
can be adjusted separately for the driver's
and front-passenger side as well as for the
rear compartment. You can control the air-
flow separately for the front and rear com-
partments. General notes
Thermatic 2-zone automatic climate control/
Thermotronic luxury multi-zone automatic cli-
mate control* controls the temperature and
the humidity of the vehicle interior and filters
out undesirable substances from the air.
Thermatic 2-zone automatic climate control/
Thermotronic luxury multi-zone automatic cli-
mate control* is only operational when the
engine is running. 25
Optimum operation is
only achieved when you drive with the side
windows and sliding/tilting sunroof* closed.
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the con-
venience opening feature (Y page 87). 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 amount
of air supplied to the vehicle interior. For
this reason, you should always observe the
interval for replacing the filter, which is
specified in the Service Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet. G
Risk of accident
Observe the recommended settings on the
following pages. Otherwise, the windows
could mist up. This may prevent you from
observing the traffic conditions, thereby caus-
ing an accident.
25 The "residual heat" function can only be switched on/off when the ignition is switched off. Air conditioning

Notes on the auxiliary heating/ventila-
tion system G
Risk of poisoning
Exhaust fumes are produced when the auxili-
ary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You should
therefore switch off the auxiliary heating in
confined spaces without an extraction sys-
tem, e.g. a garage. G
Risk of fire
When operating the auxiliary heating, parts of
the vehicle may become very hot, and highly
inflammable material such as fuels could be
ignited. Operating the auxiliary heating is thus
prohibited at filling stations or when your vehi-
cle is being refuelled. You must therefore Air conditioning

G
Risk of injury
Children could injure themselves if they oper-
ate the sliding sunroof.
Never leave children unsupervised in the vehi-
cle. Always take the key with you when leaving
the vehicle, even if you are only leaving it for
a short time. G
Risk of injury
The glass in the panorama sunroof could
break in an accident. If you are not wearing a
seat belt, there is a risk that you could be
thrown through the opening in the event of the
vehicle overturning. Therefore, always wear a
seat belt to reduce the risk of injuries.
! Only open the panorama sliding sunroof
if it is free of snow and ice. Otherwise, mal-
functions may occur.
Do not allow anything to protrude from the
sliding sunroof. The seals could otherwise
be damaged.
i When the sliding sunroof is open, apart
from the normal airflow noises resonance
noises may also occur. They are caused by
minor pressure fluctuations in the vehicle
interior. Change the position of the sliding
sunroof or open a side window slightly to
reduce or eliminate these noises.

Loading guidelines
G
Risk of injury
Secure and position the load as described in
the loading guidelines.
Otherwise, vehicle occupants could
be injured by the load being thrown around in
the event of sharp braking, a sudden change
in direction or an accident.
You will find further information in the "Secur-
ing a load" section.
Even if you follow all the loading guidelines,
the load will increase the risk of injury in the
event of an accident. G
Risk of poisoning
Keep the tailgate closed when the engine is
running. Otherwise, you could be poisoned by
exhaust fumes entering the vehicle.
The handling characteristics of a laden vehi-
cle are dependent on the distribution of the
load within the vehicle. For this reason, you
should observe the following notes when
transporting a load:
R never exceed the maximum permissible
gross vehicle weight or the permissible axle
loads for the vehicle (including occupants).
R position heavy loads as far forwards and as
low down in the luggage compartment as
possible.
R the load must not protrude above the upper
edge of the seat backrests.
R always place the load against the rear or
front seat backrests. Make sure that the Loading and stowing

Roof rack system*
G
Risk of accident and injury
An incorrectly secured roof rack, ski rack or
load could become detached from the vehi-
cle. These objects may be thrown around and
can injure you or others, or cause an accident.
Follow the roof rack/ski rack manufacturer's
installation instructions and special instruc-
tions for use.
The roof load raises the vehicle's centre of
gravity, thereby affecting vehicle handling.
You must always observe the maximum roof
load of 100 kg. Always adapt your driving style
to the prevailing road, traffic and weather
conditions and drive with particular care if the
roof is laden.
! Mercedes-Benz recommends that you
only use roof rack systems which have
been tested and approved for Mercedes-
Benz vehicles. This helps to prevent dam-
age to the vehicle.
Position the load on the roof rack in such a
way that the vehicle will not sustain dam-
age even when it is in motion.
Depending on the vehicle's equipment,
make sure that you can:
R raise the sliding/tilting sunroof* fully
R open the tailgate fully X
Secure the roof carrier to roof rails :.
Observe the manufacturer's installation
instructions. Cross bar To make it easier to attach the cross bars,
there are marks on the roof rails. These indi-
cate the best positions for fitting the cross
bars. :

Risk of accident
Keep the mirrors in the sun visors covered
while driving. Otherwise, you could be daz-
zled, impairing your view of traffic conditions.
As a result, you could cause an accident. Features

it is too low for the current operating condi-
tions.
Driving with tyre pressure that is too high or
too low can:
R shorten the service life of the tyres
R increase the likelihood of tyre damage
R have a negative effect on handling charac-
teristics (e.g. by causing aquaplaning)
i The tyre pressure values given for low
loads are minimum values which offer you
good ride comfort characteristics.
However, you can also use the values given
for higher loads. These are permissible and
will not adversely affect the running of the
vehicle.
Also check the tyre pressure of the spare
wheel* or "Minispare" emergency spare
wheel*. H
Environmental note
Check the tyre pressure regularly, at least
every 14 days. Tyre pressure loss warning
While the vehicle is in motion, the tyre pres-
sure loss warning system monitors the set
tyre pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss in a tyre. If the speed
of rotation of a wheel changes as a result of
a loss of pressure, a corresponding warning
message will appear in the multi-function dis-
play. G
Risk of accident
The tyre pressure loss warning system does
not warn you of an incorrectly set tyre pres-
sure. The table on the inside of the fuel filler
flap will help you decide whether the tyre
pressures should be corrected.
The tyre pressure loss warning system does
not replace the need to regularly check your
vehicle's tyre pressures, since an even loss of pressure on several tyres at the same time
cannot be detected by the tyre pressure loss
warning system.
The tyre pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tyre is penetrated by a foreign object.
In the event of a sudden loss of pressure, bring
the vehicle to a halt by braking carefully. Do
not make any sudden steering movements
when doing so.
The function of the tyre pressure loss warning
system is limited or delayed if:
R snow chains are fitted to your vehicle's
tyres.
R road conditions are wintry.
R you are driving on sand or gravel.
R you adopt a very sporty driving style (cor-
nering at high speeds or driving with high
rates of acceleration).
R you are towing a very heavy or large trailer.
R you are driving with a heavy load (in the
vehicle or on the roof).
Restarting the tyre pressure loss warn-
ing system Restart the tyre pressure loss warning system
if you have:
R
changed the tyre pressure
R changed the wheels or tyres
R fitted new wheels or tyres
X Before restarting, consult the table of tyre
pressures on the inside of the fuel filler flap
to ensure that the tyre pressure in all four
tyres is set correctly for the respective
operating conditions.
X Observe the notes in the section on tyre
pressures (Y page 180). 182
