Automatic transmission
Important safety notes
GWARNING
If the engine speed is above the idling speed
and you engage transmission position Dor R,
the vehicle could pull away suddenly. There is
a risk of an accident.
When engaging transmission position Dor R,
always firmly depress the brake pedal and do not simultaneously accelerate.
GWARNING
The automatic transmission switches to neu-
tral position Nwhen you switch off the engine.
The vehicle may roll away. There is a risk of an
accident.
Before switching off the engine, always switch
to parking position P. Prevent the parked vehi-
cle from rolling away by applying the parking
brake.
!If the engine is switched off, rolling in neutral
N can damage the power transmission and
result in transmission damage.
Always observe the instructions and safety
notes under "Tow starting and towing away"
(
Ypage 274).
Bear in mind that power transmission between
the engine and the transmission is interrupted
when the engine is switched off. For this reason,
shift the automatic transmission to Pbefore the engine is switched off and with the vehicle is
stationary. Apply the parking brake to prevent
the vehicle from rolling away.

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
(
Ypage 130).
If you restrict the shift range, the transmission
position indicator shows the current transmis-
sion position plus restricted shift range =, e.g.
D2 (
Ypage 128).
The arrows in the transmission position display
show how and into which transmission positions
you can change using the DIRECT SELECT lever.
Changing gear
The 7-speed automatic transmission adapts to
your individual driving style by continuously
adjusting its shift points. These shift point
adjustments take into account the current oper-
ating and driving conditions. If the operating or
driving conditions change, the automatic trans-
mission reacts by adjusting the gearshift pro-
gram.
The 7-speed automatic transmission shifts to
the individual gears automatically when it is in
transmission position D. This depends on:
Rthe drive program selected (Ypage 129)
Rany restriction in the shift range
(Ypage 128)
Rthe position of the accelerator pedal
Rthe road speed
You can also change gear manually if you select
drive program M(
Ypage 130).
Shift ranges
:To shift down and restrict the shift range
;To shift up and derestrict the shift range
In transmission position Dand drive programs E
and C, you can use the steering wheel paddle
shifters to change gear yourself and restrict or
derestrict the shift range of the automatic trans-
mission.
XTo shift down and restrict the shift range:
briefly pull left steering wheel paddle
shifter :.
The automatic transmission shifts to the next
gear down, depending on the gear currently
engaged. The shift range is also restricted.
The transmission position indicator also
shows the set shift range, e.g. D2. The auto-
matic transmission shifts only as far as the
relevant gear.
or
XPull and hold left steering wheel paddle
shifter :.
The automatic transmission will shift to a
range which allows easy acceleration and
deceleration. To do this, the automatic trans-
mission shifts down one or more gears and
restricts the shift range.
The transmission position indicator also
shows the set shift range, e.g. D2. The auto-
matic transmission shifts only as far as the
relevant gear.
The automatic transmission does not shift
down if you pull the left steering whee l p
addle
shifter whilst traveling at too high a speed. If
the maximum engine speed for the restricted
shift range is reached and you continue to
depress the accelerator pedal, the automatic transmission will shift up automatically. This
protects the engine from overrevving.

134Parking
Driving and parking
Mercedes-Benz recommends that you have the
maximum permissible speed programed at a
Mercedes-Benz Commercial Van Center.
Before overtaking, take into consideration that
the engine speed limiter prevents the speed
increasing beyond the programmed permissible
maximum speed.
Driving abroad
Service
An extensive network of authorized Mercedes-
Benz Centers is also at your disposal when you
are traveling abroad. Nevertheless, please bear
in mind that service facilities or replacement
parts may not always be immediately available.
The relevant workshop directories are available
from any Mercedes-Benz Commercial Van Cen-
ter.
Fuel
In some countries, only fuels with a higher sulfur
content are available.
Unsuitable fuel can cause engine damage. You
will find information about fuel under "Service
products and capacities" (
Ypage 305).
Low-beam headlamps
General notes
When driving in countries in which traffic drives
on the opposite side of the road to the country
where the vehicle is registered, you must switch
the headlamps to symmetrical low beam. This
prevents oncoming traffic from being blinded.
Symmetrical low beam does not illuminate as
large an area of the edge of the road.
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 oppo-
site 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 subject
to certain restrictions or require special meas- ures to be taken in some countries due to vary-
ing tunnel heights and loading standards.
You can obtain information on this from any
Mercedes-Benz Commercial Van Center.
Braking
Important safety notes
GWARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding 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 2or1 in
good time (
Ypage 128).
This should be observed in particular when driv-
ing 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
GWARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. 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.
Driving tips137
Driving and parking
Z
!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 driving
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 considerably.
Maintain a greater distance to the vehicle in
front.
To remove any build-up of salt that may have
formed:
XApply the brakes at the start of the journey,
occasionally during journey and at the end of
the journey. Make sure that you do not endan-
ger other road users when doing so.
Checking the brake pad thickness
In addition to monitoring using the brake pad
wear sensor, regularly monitor and check all of
the brake pads by performing a visual inspection
to look for pad material wear.
If you are unable to check the brake wear on the
inside of the wheels, remove the wheels with the tools provided.
Make sure that the brake pad material thickness
never falls below 0.12 in (3 mm). Have the brake pads checked and replaced at a qualified spe-
cialist workshop, if necessary. Do not solely rely on the brake pad wear sensor.
It is strongly recommended that you have the
brake pads checked at a qualified specialist
workshop at every service displayed in the main-
tenance interval indicator, prior to long journeys
and whenever the wheels are removed.
New brake discs and brake pads/
linings
New brake pads and brake discs only reach their
optimal braking effect after about 60 miles
(100 kilometers). Until then, compensate for
this by applying greater force to the brake pedal.
For safety reasons, Mercedes-Benz recom-
mends only installing the following brake discs
and brake pads/linings:
Rbrake discs that have been approved by
Mercedes-Benz
Rbrake pads/linings that have been approved
by Mercedes-Benz or are of an equivalent
standard of quality
Other brake discs or brake pads/linings can
compromise the safety of your vehicle.
Always replace all brake discs or brake pads/
linings on an axle at the same time and only have
them replaced at a qualified specialist work-
shop. When replacing the brake discs, always
have the brake pads/linings replaced at the
same time.
Parking brake
GWARNING
If you must brake the vehicle with the parking brake, the braking distance is considerably
longer and the wheels could lock. There is an
increased danger of skidding and accidents.
Only use the parking brake to brake the vehi-
cle when the service brake is faulty. Do not
apply the parking brake too firmly. If the
wheels lock, release the parking brake until
the wheels begin turning again.
When driving on wet roads or dirt-covered sur-
faces, road salt and/or dirt may get into the
parking brake. This causes corrosion and a
reduction of braking force.
In order to prevent this, drive with the parking
brake lightly applied from time to time. When
doing so, drive for a distance of approximately
