Overview of driving systems
The vehicle's driving systems are described
on the following pages:
R Cruise control, Distronic* and Speedtronic,
which are used to control the speed of the
vehicle
R The rear axle level control*, which regu-
lates the vehicle level at the rear axle
R AIRMATIC package*, consisting of level
control* for individual adjustment of
ground clearance and ADS* (Adaptive
Damping System), for individual adjust-
ment of suspension tuning
R 4*MATIC (permanent four-wheel drive), for
optimum traction
R Parktronic*, which assists you in parking
and manoeuvring
R Reversing camera*, which assists you
when parking and manoeuvring
The ABS, BAS, ESP ®
, EBV vehicle safety sys-
tems and the distance warning system* are
described in the "Safety" section
(Y page 58). Cruise control
Cruise control maintains a constant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden or towing a trailer, you must
select shift range 1,2or 3in good time. By
doing so 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.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 30 km/h. G
Risk of accident
Cruise control cannot take account of road
and traffic conditions.
Always pay attention to traffic conditions
even when cruise control is activated.
Cruise control is only an aid designed to
assist driving. You are responsible for the vehicle's speed and for braking in good
time.
G
Risk of accident
Do not use cruise control:
R in road and traffic conditions which do
not allow you to maintain a constant
speed (e.g. heavy traffic or winding
roads). You could otherwise cause an
accident.
R on slippery roads. Braking or accelerat-
ing could cause the drive wheels to lose
traction and the vehicle could then skid.
R when there is poor visibility, e.g. due to
fog, heavy rain or snow
Cruise control lever You can operate cruise control and variable
Speedtronic with the cruise control lever.
The LIM indicator lamp on the cruise control
lever indicates which system you have selec-
ted:

tems 143Distronic*
i Distronic is only available for certain
countries.
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 or towing a trailer, you must select shift
range 1,2or 3in good time. By doing so you
will make use of the braking effect of the
engine, which relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly. G
Risk of accident
The brake pedal is retracted when Distronic
brakes. Do not restrict the movement of the
pedal in any way.
R Do not put any objects in the footwell.
R Ensure that floor mats and carpets are
fixed securely.
R Do not place your foot under the brake
pedal as it could become trapped.
You could otherwise cause an accident and
injure yourself and others. 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 to other vehicles,
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 danger 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 the preset distance to the vehicle in
front that you have set. G
Risk of accident
Distronic cannot take account of road and
traffic conditions. Deactivate, or do not
activate, Distronic if it does not detect the
vehicle in front, or if it no longer detects it.
This is especially the case:
R before corners
R on filter lanes
R when changing to a lane with faster mov-
ing traffic
R in complex driving situations or where
the lanes are diverted, e.g. at motorway/
roadway construction sites
Otherwise, Distronic maintains the current
speed or accelerates to the set speed.
Distronic cannot take account of weather
conditions. Deactivate, or do not activate,
Distronic:
R if the roads are slippery, snow-covered or
icy. The wheels could lose their grip Controls

of its narrow width. The distance to the vehi-
cle in front will be too short. 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 or towing a trailer, you must
select shift range 1,2or 3in good time. By
doing so 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 additional braking, depress the
brake pedal repeatedly rather than continu-
ously. 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 151) 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.

may differ slightly from the limit speed

Overview of air-conditioning systems
The vehicle is equipped with one of the following air-conditioning systems: 2-zone Thermatic
Multi-zone Thermotronic* Rear-compartment air conditioning*
242-zone Thermatic is an automatic air-condi-
tioning system combining an automatic heat-
ing and ventilation system with a cooling
system. You can control the air conditioning
separately for the driver's and front-
passenger sides. Multi-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 settings for the rear com-
partment.
