Regulating climate control automati-
cally
General notes When dual-zone automatic climate control is in
automatic mode, the set temperature is auto-
matically kept constant. The system automati-
cally regulates the temperature of the dis-
pensed air, the airflow and the air distribution.
Automatic mode will achieve optimal operation
if the cooling with air dehumidification func-
tion is also activated. If desired, the cooling
with air dehumidification function can be deac-
tivated (
Y page 118).
Dual-zone automatic climate control Automatic mode for automatic climate control
settings can only be activated or deactivated
on the first menu level. If you do not set a new
value for the rear-compartment climate control
in the second menu level within approx. ten
seconds, the control panel display goes back
to the first menu level.

off, rolling in idle i can damage
the power transmission and
result in transmission damage. 7 Drive
The automatic transmission
changes gear itself. All forward
gears are available.
You can influence gearshifts with
your choice of drive program. You
can also restrict the shift range. Transmission position and drive pro-
gram display

current gear in drive program M
= Shift range, if restricted
The transmission positions and current drive
program : are shown at the bottom of the
instrument cluster display. The current trans-
mission position is highlighted.
In drive program M, the transmission position
indicator shows the current gear in position D
( Y page
135).
If you restrict the shift range, the transmission
position indicator shows the current transmis-
sion position plus restricted shift range =,
e.g. D2 ( Y page 133).
The arrows in the transmission position display
show how and into which transmission posi-
tions you can change using the DIRECT
SELECT lever. Changing gear
The automatic transmission adapts to your
individual driving style by continuously adjust-
ing its shift points. These shift point adjust-
ments take into account the current operating
and driving conditions. If the operating or driv-
ing conditions change, the automatic transmis-
sion reacts by adjusting the gearshift program.
When the automatic transmission is in trans-
mission position h, it shifts the individual
gears automatically.
This depends on the following factors:
R the drive program selected ( Y page 134)
R any restriction in the shift range
(Y page
133)
R the position of the accelerator pedal
R the road speed
You can also change gear manually if you
select drive program M (Y page 135).132

Vehicles with halogen headlamps
The headlamps do not need to be switched to
symmetrical low beam. The legal requirements
of countries in which traffic drives on the
opposite side of the road to the country where
the vehicle is registered are met without the
need to convert the headlamps. Transport by rail
Transporting your vehicle by rail may be sub-
ject to certain restrictions or require special
measures to be taken in some countries due
to varying tunnel heights and loading stand-
ards.
You can obtain information on this from any
Mercedes-Benz Commercial Van Center. Braking
Important safety notes G
WARNING
If you shift down on a slippery road surface
in an attempt to increase the engine's brak-
ing effect, the drive wheels could lose their
grip. There is an increased danger of skid-
ding and accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients !
Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
This also applies to automatic braking if you
have activated cruise control.
On long and steep downhill gradients, you
should change down to shift range 2 or 1 in
good time
(Y page 133).
This should be observed in particular when
driving with a laden vehicle and when towing a
trailer.
You thereby make use of the braking effect of
the engine and do not have to brake as often
to maintain the speed. This relieves the load
on the service brake and prevents the brakes
from overheating and wearing too quickly. Heavy and light loads G
WARNING
If you rest your foot on the brake pedal
while driving, the braking system can over-
heat. This increases the stopping distance
and can even cause the braking system to
fail. There is a risk of an accident.
Never use the brake pedal as a footrest.
Never depress the brake pedal and the
accelerator pedal at the same time.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately.
Drive on for a short while. The brakes are
cooled down more quickly in the airflow.
Wet road surfaces If you have been driving for a long time in
heavy rain without braking, there may be a
delayed response when you first apply the
brakes. This may also occur after driving
through a car wash or deep water.
You must depress the brake pedal more firmly.
Maintain a longer distance to the vehicle in
front.
While paying attention to the traffic conditions,
you should brake the vehicle firmly after driv-
ing on a wet road surface or through a car
wash. This heats the brake discs, so that they
dry more quickly, which protects them against
corrosion.
Limited braking performance on salt-
treated roads When driving on salted roads, salt may start to
build up on the brake disks and brake pads.
This can increase braking distances considera-
bly.
Maintain a greater distance to the vehicle in
front.
To remove any build-up of salt that may have
formed:
X Apply the brakes at the start of the journey,
occasionally during journey and at the end 142
