Only use this operating mode for a short time, e.g. in
a tunnel. Otherwise, the windows can mist up due to
lack of fresh air. (
Y page 170 ) General notes
Optimum operation of Thermotronic is only
achieved when you drive with the side win-
dows and sliding/tilting sunroof*/panorama
sliding/tilting sunroof* closed
.
You can allow the air-conditioning system to
adjust automatically or you can adjust it man-
ually.
In automatic mode, Thermotronic cools or
heats the vehicle interior according to:
R The selected temperature
R The outside temperature
R The intensity of the sunlight
i Ventilate the vehicle for a brief period
during warm weather, e.g. using the sum-
mer opening feature (Y page 111). This helps you to achieve the desired interior
temperature more quickly.
The integrated filter filters out most particles
of dust and completely filters out pollen.
i A clogged filter reduces the amount of ai r
supplied to the vehicle interior. For this rea-
son, you should always observe the interval
for replacing the filter, which is specified in
the Service Booklet. As it depends on envi-
ronmental conditions, e.g. heavy air pollu-
tion, the interval may be slightly shorter
than stated in the Service Booklet. G
Risk of accident
Follow the settings recommended on the
following pages for heating or cooling. The
windows could otherwise mist up. This may prevent you from observing the traffic con-

Driving
tips 21

Downhill gradient
sOn long and steep downhill stretches, espe-
cially if the vehicle is laden or towing a trailer,
you must shift to a lower gear in good time or,
on vehicles with automatic transmission*,
select shift range 1,2 or 3.
i This also applies if you have activated
cruise control* or Speedtronic*.
This uses the braking effect of the engine and
you will not have to brake to such an exten t
to maintain the same speed. This relieves the
load on the brake system and prevents the
brakes from overheating and wearing too
quickly. If you need additional braking ,
depress the brake pedal repeatedly rather
than continuously.
Heavy and light loads If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately, but
drive on for a short while. This allows the air-
flow to cool the brakes more quickly. G
Risk of accident
Never depress the brake pedal continu -
ously while the vehicle is in motion, e.g.
never cause the brakes to rub by applying constant slight pedal pressure. This causes
the brake system to overheat, increases
the braking distance and can lead to the
brakes failing completely.
If the brakes have been used only moderately,
you should occasionally test their effective-
ness. To do this, brake more firmly from a
higher speed. This improves the grip of the
brakes.
Wet roads If you drive for a long time in the rain without
braking, there may be a delayed reaction
when you first brake and you will have to
depress the pedal harder.
You must therefore maintain a greater dis-
tance from the vehicle in front.
Brake firmly after driving on a wet road. Thi
s
way the brake discs will become warm, dryin g
more quickly, which will protect them against
corrosion. Limited braking performance on salted
roads G
Risk of accident
The layer of salt on the brake discs and the
brake linings may cause a delay in the brak-
ing effect, resulting in a significantly longer
braking distance, which could lead to an
accident.
To avoid this danger, you should:
R occasionally brake carefully when you
are driving on salted roads, so that any
layer of salt that may have started to
build up on the brake discs and the brake
linings is removed without putting other
road users at risk.
R maintain a greater distance to the vehicl e
ahead and drive with particular car e
R carefully apply the brakes at the end of a
trip and immediately after commencing a
new trip, so that salt residues ar e
removed from the brake disc.
New brake linings For safety reasons, Mercedes-Benz recom
-
mends that you have only brake pads/linings
fitted to your vehicle that have been approved Operation

Risk of accident and injury
Always have maintenance work carried out at a qualified specialist workshop which has the necessary specialist knowledge and tools to
carry out the work required .
Mercedes-Benz recommends that you use a Mercedes-Benz Service Centre for this purpose.
In particular, work relevant to safety or on safety-related systems must be carried out at a qualified specialist workshop. The operating
safety of the vehicle can be affected if this work is carried out incorrectly. There is a risk of accident and injury. Indicator and warning lamps in switches and buttons
Problem Possible cause/consequence Suggested solutions
The seat heating* has switched
itself off prematurely or cannot
be switched on. There is insufficient voltage
because too many consumers are
switched on. X
Switch off consumers that are not required, e.g. reading lamps ,
interior lighting, etc .
The seat heating* will automatically switch back on as soon as
there is sufficient voltage again. The warning lamp on the sport
button of the ADVANCED AGILITY
package with sports mode* is lit. If you select comfortable mode
and the indicator lamp does not
go out, the ADVANCED AGILITY
package with sports mode* is
faulty. X

Turn the jack back to its initial position and
store it and the rest of the vehicle tool kit
in the boot/luggage compartment.
Vehicles with the "Minispare" emergency
spare wheel*:
X Transport the faulty wheel in the boot/lug-
gage compartment.
or
X Depending on the size of the wheel, yo u
may also be able to secure the faulty whee l
in the spare wheel well. In this case, you
will have to remove the stowage well casin g
from the spare wheel well and stow it
securely in the boot/luggage compart-
ment. MOExtended run-flat system*
The MOExtended run-flat system* must only
be used in conjunction with the tyre pressure
loss warning system*.
! The maximum permissible distance which
can be driven in run-flat mode depends on
the load in the vehicle. It is 50 km if the
vehicle is partially laden and 30 km if fully
laden. The maximum permissible distance which
can be driven in run-flat mode is counted
from the moment the tyre pressure loss
warning appears in the multi-function dis-
play.
You must not exceed a maximum speed of
80 km/h.
i Vehicles featuring the MOExtended run-
flat system* are not equipped with the
TIREFIT kit*.
It is therefore recommended to additionally
equip your vehicle with the TIREFIT kit*
when fitting tyres that do not feature run-
flat properties, e.g. winter tyres.
i A TIREFIT kit* is available from any quali-
fied specialist workshop, e.g. a Mercedes-
Benz Service Centre. G
Risk of accident
The handling characteristics of your vehicl e
deteriorate in run-flat mode, for example:
R when cornering
R when braking
R when accelerating rapidly
Adapt your driving style accordingly and
avoid sudden changes in direction and sud- den acceleration, as well as driving over
obstacles (i.e. kerbs, potholes), and driving
off-road. This is particularly the case when
the vehicle is heavily laden .
The maximum permissible distance that
can be driven in run-flat mode depends to
a large extent on the loads placed on the
vehicle. It can be shorter due to high
speeds, a heavy load, sudden acceleration
and/or manoeuvring, the road surface con-
dition, outside temperature, etc., or further
if you drive carefully and conservatively.
Do not continue to drive in run-flat mode if:
R you hear banging noises
R the vehicle starts to shake
R you see smoke and smell rubber
R ESP ®
is intervening constantly
R there are tears in the sidewalls of the tyr e
After driving in run-flat mode, you must
have the rims checked for damage at a
qualified specialist workshop which has the
necessary specialist knowledge and tools
to carry out the work required. The faulty
tyre must be replaced in every case.
Mercedes-Benz recommends that you use
a Mercedes-Benz Service Centre for this Practical advice
