Transmission positions
B Park position
This prevents the vehicle from roll-
ing away when stopped. Only shift
the transmission to
j when the
vehicle is stationary.
The automatic transmission shifts
to j automatically in the following
situations:
R if you pull out the key.
R if you open the driver's door
when the vehicle is stationary or
when driving at a very low speed
and the transmission is in posi-
tion h or k.
The parking lock should not be used
as a brake when parking. Always
apply the parking brake as well
once you have parked the vehicle. C Reverse gear
Only shift the transmission to
k
when the vehicle is stationary. A Neutral
No power is transmitted from the
engine to the drive wheels. Releas-
ing the brakes will allow you to
move the vehicle freely, e.g. by
pushing or towing.
If ESP
®
is deactivated or faulty: shift
the transmission to position i if
the vehicle is in danger of skidding,
e.g. on icy roads.
When you switch off the engine, the
automatic transmission automati-
cally shifts into neutral i.
! When the engine is switched
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
:
Drive program
; Current transmission position or
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

Shift ranges
:
To shift down and restrict the shift range
; To shift up and derestrict the shift range
In transmission position h and drive pro-
grams 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 transmission.
X To 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 cur-
rently 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 X Pull 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
transmission 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 wheel pad-
dle 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. X
To shift up and extend the shift range:
briefly pull right steering wheel paddle
shifter
;.
The automatic transmission shifts to the
next gear up, depending on the gear cur-
rently engaged. This derestricts the shift
range at the same time.
If the display shows only transmission posi-
tion h, the shift range restriction is can-
celed.
X To derestrict the shift range: pull and hold
right steering wheel paddle shifter ;.
The automatic transmission shifts up one or
more gears depending on the gear currently
engaged. At the same time, the shift range
restriction is canceled and the display
shows transmission position D .

Drive programs
General notes You can use the program selector button to
choose between different drive programs for
the automatic transmission, depending on the
engine. Engine management and the gearshift-
ing characteristics of the automatic transmis-
sion change depending on which drive pro-
gram is selected. Thus, a more comfort-orien-
ted, a more economical, or a sportier driving
style is supported, depending on the wish of
the driver. Selecting drive program M deacti-
vates automatic gearshifting, requiring that
you change gear manually.
After the engine is started, the automatic
transmission automatically switches to drive
program C (Comfort) for a comfortable and
economical driving style. Automatic transmission

Kickdown
Use kickdown for maximum acceleration:
X Depress the accelerator pedal beyond the
pressure point.
The automatic transmission shifts to the
next gear down, depending on the engine
speed.
X Ease off on the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts up again.
Rocking the vehicle free At speeds up to 5 mph (9 km/h) you can
switch back and forth between drive position
h and reverse gear
k without applying the
brakes. This helps when rocking the vehicle
out of snow or slush.
X Push the DIRECT SELECT lever alternately
up and down beyond the first point of resist-
ance.
Towing a trailer X
Depending on the downhill gradient, limit
the shift range
(Y page 133) or shift man-
ually into a lower gear (Y page 135) in which the engine will operate in the middle
of the engine speed range. This also applies
if cruise control is activated. Manual gearshifting
General notes If you select drive program
M, automatic gear-
shifting is deactivated and manual gearshifting
is automatically activated. You must then per-
manently change gear yourself for as long as
the drive program is selected.
Permanent manual gearshifting is deactivated
automatically when you switch from drive pro-
gram M to another drive program. The auto-
matic transmission then shifts gears automati-
cally. The display shows the selected drive
program and transmission position h again. Shifting gears

General notes
Important safety notes G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could
affect, for example, the power steering and
the brake boosting effect. You will require
considerably more effort to steer and brake.
There is a risk of an accident.
Do not switch off the ignition while driving. G
WARNING
Mobile communications equipment distracts
the driver from traffic conditions. In addi-
tion, the driver could lose control of the
vehicle. There is a risk of an accident.
As a driver, use mobile communications
equipment only when the vehicle is at a
standstill.
As a vehicle occupant, use mobile communi-
cations equipment only in the designated
area, e.g. the rear passenger compartment. Observe the legal requirements of the country
in which you are driving. Some jurisdictions
prohibit the driver from using a mobile phone
while driving a vehicle.
Always use the hands-free system for tele-
phoning while driving. Only use the telephone
if road traffic conditions permit. If this is not
the case, pull over to a safe location before
using the telephone.
Bear in mind that at a speed of just 30 mph
(approximately

50 km/h), your vehicle is cov-
ering a distance of 44 feet (approximately
14 m) every second.
Drive sensibly – save fuel In order to save fuel, observe the following
tips:
X The tires should always be inflated to the
recommended tire pressure.
X Remove unnecessary loads.
X Remove roof carriers when they are not nee-
ded.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all maintenance work carried out as
indicated by the service intervals in the
Maintenance Booklet or by the service inter-
val display.
Fuel consumption also increases when driving
in cold weather, in stop-start traffic and in
mountainous terrain.
Overrun cutoff If you are in overrun mode and take your foot
off the accelerator pedal, the fuel supply is cut
off when the engine speed is out of the idle
speed control range.
Drinking and driving G
WARNING
Drinking and driving and/or taking drugs
and driving are very dangerous combina-
tions. Even a small amount of alcohol or
drugs can affect your reflexes, perceptions
and judgment.
The possibility of a serious or even fatal
accident is greatly increased when you drink
or take drugs and drive. 140
Driving tips
Driving and parking

Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.
Emission control G
DANGER
Combustion engines emit poisonous
exhaust gases such as carbon monoxide.
Inhaling these exhaust gases is hazardous to
health and can result in poisoning. There is a
risk of fatal injury. Therefore, never leave the
engine running an enclosed space without
adequate ventilation.
Certain engine systems are designed to keep
the level of poisonous substances in exhaust
fumes within legal limits.
These systems only work optimally if they are
maintained exactly in accordance with the
manufacturer's specifications. Any work on
the engine should therefore be carried out by
qualified and authorized Mercedes-Benz tech-
nicians.
The engine settings must not be changed
under any circumstances. In addition, all spe-
cific maintenance work must be carried out at
regular intervals and in accordance with the
service requirements of the dealer listed here
on the inside title page. Details can be found
in the Maintenance Booklet. Speed limiter
G
WARNING
Exceeding the stated tire load-bearing capa-
city and the approved maximum speed
could lead to tire damage or the tire burst-
ing. There is a risk of accident.
Therefore, only use tire types and sizes
approved for your vehicle model. Observe
the tire load rating and speed rating
required for your vehicle.
As the driver, you must be aware of the maxi-
mum design speed of the vehicle and the max-
imum permissible speed based on the tires
(tire and tire pressure). In particular, also observe the tire approval regulations for each
country.
You must not exceed the speed limit for the
tires indicated by the speed rating. The speed
rating is stated in the tire tables (Y page
302).
You can permanently limit the permissible
maximum speed of your vehicle, e.g. for driv-
ing on winter tires.
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 permissi-
ble 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 replace-
ment parts may not always be immediately
available. The relevant workshop directories
are available from any Mercedes-Benz Com-
mercial Van Center.
Fuel In some countries, only fuels with a higher sul-
fur content are available.
Unsuitable fuel can cause engine damage. You
will find information about fuel under "Service
products and capacities"

(Y page 306).
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. Driving tips
141
Driving and parking Z

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
