X
Briefly press the cruise control lever in the
direction of arrow 5.
Variable Speedtronic is selected. LIM indi-
cator lamp 2 in the cruise control lever
lights up.
Cruise control is automatically deactivated if,
for example:
R you depress the parking brake
R you are driving at less than
30 km/h
R ESP ®
(Y page 59) is intervening or you
deactivate ESP ®
R you move the selector lever to N while driv-
ing
If cruise control is deactivated, you will hear
a warning tone. You will see the Cruise con-
trol off message in the multi-function dis-
play for approximately five seconds.
i The last speed stored is cleared when you
switch off the engine. Distronic*
Distronic regulates the speed and automati-
cally maintains the distance to the vehicle in
front.

It brakes automatically in order to avoid
exceeding the set speed. On long and steep
downhill gradients, especially if the vehicle is
laden, you must select shift range 1, 2 or 3 in
good time. In this way you will make use of
the braking effect of the engine, which
relieves the load on the brake system and
prevents the brakes from overheating and
wearing too quickly. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This
could cause the drive wheels to lose their
grip and the vehicle could skid. G
Risk of accident
Distronic is only an aid designed to assist
driving.
The driver remains fully responsible
for the vehicle's distance from other vehi-
cles, the vehicle's speed and braking in
good time. Distronic does not react to: R
pedestrians
R stationary

obstacles on the road, e.g. sta-
tionary or parked vehicles
R oncoming and crossing traffic
Distronic may not detect narrow vehicles
driving in front, e.g. motorcycles, or vehi-
cles driving on a different line. Therefore,
always pay attention to traffic conditions
even when Distronic is activated. Other-
wise, you may fail to recognise dangers in
time, could cause an accident and injure
yourself and others.
If a slower-moving vehicle is detected in front,
Distronic causes your vehicle to brake and
maintain a preset distance to the vehicle in
front. G
Risk of accident
Distronic cannot take account of road and
traffic conditions. Deactivate, or do not
activate, Distronic in situations in which
Distronic maintains the speed or acceler-
ates

to the set speed because it has lost the
vehicle in front, in particular:
R before corners
R on filter lanes Controls

142 Speedtronic
Speedtronic brakes automatically so that you
do not exceed the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden, you must select shift range
1, 2 or 3 in good time. In this way you will
make use of the braking effect of the engine,
which relieves the load on the brake system
and prevents the brakes from overheating
and wearing too quickly. If you need addi-
tional braking, depress the brake pedal
repeatedly rather than continuously. 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. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This
could cause the drive wheels to lose their
grip and the vehicle could skid. You can set a variable or permanent limit
speed:
R
Variable for speed limits, e.g. in built-up
areas
R Permanent for long-term speed restric-
tions, e.g. for driving on winter tyres
(Y page 144) G
Risk of accident
Speedtronic is only an aid designed to
assist driving. You are responsible for the
vehicle's speed and for braking in good
time.
i The speed indicated in the speedometer
may differ slightly from the limit speed
stored.
Variable Speedtronic With the cruise control lever you can operate
cruise control, Distronic* and variable
Speedtronic.
The LIM indicator lamp on the cruise control
lever indicates which system you have selec-
ted:
R
LIM indicator lamp off: Cruise control or Distronic* is selected
R LIM indicator lamp lit:
variable Speedtronic is selected
You can use the cruise control lever to limit
the speed to any speed above 30 km/h while
the engine is running. 1

151Air conditioning
Overview of the control panels
The vehicle is equipped with one of the following air-conditioning systems: 2-zone Thermatic
4-zone Thermotronic*
Rear-compartment air conditioning*
192-zone Thermatic is an automatic air-condi-
tioning system combining an automatic heat-
ing and ventilation system with a cooling
system. 4-zone Thermotronic is a luxury automatic
air-conditioning system combining an auto-
matic heating and ventilation system with a
cooling system. You can control the air con-
ditioning separately for each zone in the vehi-
cle. The rear-compartment air conditioning
allows separate temperature settings for the
rear compartment.
19
Rear-compartment air conditioning is only available in conjunction with 4-zone Thermotronic. Controls

Risk of accident
Clear all windows of ice or snow before set-
ting off. Impaired visibility could otherwise
endanger yourself and others.
i At very low temperatures, the rear win-
dow heating is only switched on once the
vehicle interior has warmed up.
i The rear window heating has a high cur-
rent draw. You should therefore switch it
off
as soon as the window is clear, as it only
switches itself off automatically after
between six and twenty minutes.
i If the battery voltage is too low, the rear
window heating may switch off.
X Make sure that the key is in position 2 in
the ignition lock.

tion mode
You can deactivate the flow of fresh air if
unpleasant odours are entering the vehicle
from outside. The air already inside the vehi-
cle will then be recirculated. G
Risk of accident
Only switch over to air-recirculation mode
briefly
at low outside temperatures. Other-
wise, the windows could mist up, thus
impairing visibility and endangering your-
self and others. This may prevent you from
observing the traffic conditions, thereby
causing an accident.
X To activate: press the , button.
The indicator lamp in the , button
comes on.
i Air-recirculation mode is activated auto-
matically at high outside temperatures.
When air-recirculation mode is activated
automatically, the indicator lamp in
the , button is not lit.
Outside air is added after about 30
minutes. Controls
