Exhaust gases can enter the vehicle interior
if the tailgate is open while the engine is
running, especially if the vehicle is in
motion. There is a risk of poisoning.
Always switch off the engine before opening
the tailgate. Never drive with the tailgate
open.
! The tailgate swings upwards and to the
rear when opened. Therefore, make sure
that there is sufficient clearance above and
behind the tailgate.

Notes on trailer towing
Important safety notes G
WARNING
Installing an unsuitable ball coupling may
overload the trailer tow hitch and the rear
axle. This is particularly likely in the case of
longer or differently angled ball couplings.
Consequently, the driving characteristics
may be significantly impaired and the trailer
may detach. This presents the risk of an
accident or even fatal injuries!
Install only a ball coupling that adheres to
the permissible dimensions and is designed
for your intended purpose for towing a
trailer. Do not make any changes to the ball
coupling or the trailer tow hitch. G
WARNING
If you install a ball coupling other than the
one delivered with the vehicle, the trailer
tow hitch and the rear axle may be overloa-
ded. This applies especially if the ball cou-
pling in question is longer or angled differ-
ently. This could seriously impair the driving
characteristics and the trailer can come
loose. There is a risk of an accident. Only install the ball coupling delivered with
the vehicle or a ball coupling that is
designed to meet your trailer towing require-
ments. Do not modify the ball coupling or
the trailer tow hitch.
G
WARNING
If the ball coupling is not correctly installed
and secured, it could come loose while driv-
ing and endanger other road users. There is
a risk of accident and injury, possibly even
fatal injuries.
Install and secure the ball coupling as
described in the ball coupling manufactur-
er's installation instructions. Make sure that
the ball coupling is correctly installed and
secured before every journey. G
WARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The
vehicle/trailer combination could even roll-
over. There is a risk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combina-
tion by increasing the speed. Reduce vehicle
speed and do not countersteer. Apply the
brake as necessary.
You can attach carrier systems such as bicycle
racks or load-bearing implements on the ball
coupling. The maximum load-bearing capacity
of 165 lb (75 kg

) applies when using carrier
systems on the ball coupling.
Always observe the operating instructions pro-
vided by the manufacturers of the trailer cou-
pling and the ball coupling.
Couple and decouple the trailer carefully.
When backing up the towing vehicle, make
sure nobody is standing between the vehicle
and the trailer.
A trailer which is incorrectly coupled to the
towing vehicle could break away. A correctly
coupled trailer must be positioned horizontally
behind the towing vehicle. 168
Towing a trailer
Driving and parking

not depress the brake pedal constantly, but
periodically.
Observe the notes on ESP
®
trailer stabilization
( Y page
69).
Driving tips If the trailer begins to swing from side to side:
X Do not accelerate.
X Do not counter-steer.
X Brake if necessary.
i You can reduce the risk of the trailer
swinging and rocking by retrofitting anti-roll
bars or trailer stability programs. Further
information is available at your authorized
Mercedes-Benz Van Dealer.
R Maintain a greater distance than you would
when driving without towing a trailer.
R Avoid sudden braking. Apply the brakes gen-
tly at first to allow the trailer brake to over-
run. Then, increase the brake force quickly.
R The figures for the gradient climbing capa-
bilities from a standstill refer to sea level.
When driving in mountainous areas, note
that the power output of the engine, and
with it its gradient climbing capability,
decrease with increasing altitude. Coupling up a trailer
Trailer coupled ready for use X
Make sure that the selector lever of the
automatic transmission is in position j.
X On vehicles with an automatic transmission,
ensure that the transmission is in position
j.
X Engage the vehicle's parking brake.
X Close all doors.
X Position the trailer horizontally behind your
vehicle.
X Couple the trailer.
X Establish all electrical and other connec-
tions to the trailer. When doing so, hook the
breakaway cable of the trailer into the eye-
let on the ball coupling.
X Remove the objects that are preventing the
trailer from rolling, e.g. wheel chocks.
X Release the trailer parking brake.
Observe the maximum permissible trailer
dimensions (width and length).
Most federal states and all Canadian provinces
require by law: R Safety chains between the towing vehicle
and the trailer. The chains should be cross-
wound under the trailer drawbar. They must
be fastened to the vehicle's trailer coupling,
not to the bumper or the axle.
Leave enough slack in the chains. This
allows you to drive round tight corners.
R A separate brake system for certain types of
trailer.
R A safety shut-off for braked trailers. Find out
the specific requirements according to the
applicable laws.
If the trailer becomes detached from the
towing vehicle, the safety shut-off applies
the trailer brakes. Towing a trailer
There are numerous legal requirements con-
cerning the towing of a trailer, e.g. speed
restrictions. Many states require a separate
functional braking system for your trailer once
a certain weight limit is exceeded. For reasons
of safety, it is recommended that all trailers
use a separate functional braking system.
Make sure your vehicle/trailer combination
complies with local laws. This not only means
where you live, but also anywhere you are driv-
ing to. Information on this can be obtained
from the police and local authorities. 170

Useful information
This Operator's Manual describes all models
as well as standard and optional equipment of
your vehicle that were available at the time of
going to print. Country-specific variations are
possible. Note that your vehicle may not be
equipped with all of the described functions.
This also applies to systems and functions rel-
evant to safety.
Read the information on qualified specialist
workshops (Y page
32).Important safety notes
G
Warning
A flat tire severely impairs the driving, steer-
ing and braking characteristics of the vehi-
cle. There is a risk of an accident.
do not drive with a flat tire. Immediately
replace the flat tire with your spare wheel,
or consult a qualified specialist workshop. G
WARNING
If you install wheels and tires with incorrect
dimensions, the service brake or wheel sus-
pension components may be damaged.
There is a risk of an accident.
Always replace wheels and tires with ones
that comply with the specifications of the
original part.
When replacing wheels, pay attention to the:
R Designation
R Model
When replacing tires, pay attention to the:
R Designation
R Manufacturer
R Model
Accessories that are not approved for your
vehicle by Mercedes-Benz or are not being
used correctly can impair operating safety. Before purchasing and using non-approved
accessories, visit a qualified specialist work-
shop and inquire about the following points:
R
suitability
R legal stipulations
R factory recommendations
Information on the dimensions and types of
wheels and tires for your vehicle can be found
under "Wheel and tire combinations"
( Y page
301).
Information on your vehicle's tire pressures
can be found in the following locations:
R in the Tire and Loading Information placard
on the B-pillar, driver's side
R in the tire pressure table inside the fuel filler
flap ( Y page 282)
R under "Tire pressure tables" (Y page 289)
R under "Tire pressure" (Y page 282)
Modifications to the brake system or wheels
are not permitted. The use of spacers or brake
dust shields is not permitted. This invalidates
the general operating permit for the vehicle.
Further information on wheels and tires can be
obtained at any qualified specialist workshop. Operation
Information for a journey
If the vehicle is heavily laden, check the tire
pressures, and correct them, if necessary
( Y page

282).
While driving, pay attention to vibrations,
noises and unusual handling characteristics,
e.g. pulling to one side. This may indicate that
the wheels or tires are damaged. If you sus-
pect that a tire is defective, reduce your speed
immediately. Stop the vehicle as soon as pos-
sible to check the wheels and tires for dam-
age. Hidden tire damage could also be causing
the unusual handling characteristics. If you
find no signs of damage, have the tires and
wheels checked at a qualified specialist work-
shop.
When parking your vehicle, make sure that the
tires do not get deformed by the curb or other
obstacles. If it is necessary to drive over curbs,
speed humps or similar elevations, try to do so
slowly and not at a sharp angle. Otherwise, the
tires, particularly the sidewalls, can get dam-
aged. 278
Operation
Wheels and tires

R
Break in new tires at moderate speeds for
the first
65 miles (100 km).
R Do not drive with tires which have too little
tread depth, as this significantly reduces the
traction on wet roads (hydroplaning).
R Replace the tires after six years at the lat-
est, regardless of wear. This also applies to
the spare wheel. Operation in winter
General notes
Have your vehicle winterized at a qualified spe-
cialist workshop at the onset of winter.
Only use wheels with tire sizes approved for
Mercedes-Benz.
Prior to the onset of winter, ensure that snow
chains are stowed in the vehicle
(Y page

281). Snow chains cannot be moun-
ted on all wheel/tire combinations. Observe
the restrictions on the use of snow chains
under "Wheel/tire combinations"
(Y page 302).
Also observe the notes in the "Changing a
wheel" section ( Y page 297).Driving with summer tires
At temperatures below 45 ‡
(+7 †), summer
tires lose elasticity and therefore traction and
braking power. Change the tires on your vehi-
cle to M+S tires. Using summer tires at very
cold temperatures could cause tears to form,
thereby damaging the tires permanently.
Mercedes-Benz cannot accept responsibility
for this type of damage. M+S tires
G
WARNING
Wheel and tire dimensions as well as the
type of tire can vary between the spare
wheel and the wheel to be replaced. When
the spare wheel is mounted, driving charac-
teristics may be severely affected. There is a
risk of an accident. In order to reduce risks:
R you should therefore adapt your driving
style and drive carefully.
R never mount more than one spare wheel
that differs from the wheel to be replaced.
R only use a spare wheel that differs from
the wheel to be replaced for a short time.
R have a spare wheel that differs from the
wheel that has been changed replaced at
the nearest qualified specialist workshop.
You must observe the correct wheel and
tire dimensions as well as the wheel type. G
WARNING
M+S tires with a tire tread depth of less than
ã in
(4 mm) are not suitable for use in win-
ter and do not provide sufficient traction.
There is a risk of an accident.
M+S tires with a tread depth of less than ã
in (4 mm) must be replaced immediately.
Use winter tires or all-season tires at tempera-
tures below 45 ‡ (+7 †). Both types of tire
are identified by the M+S marking.
Only winter tires bearing the i snowflake
symbol in addition to the M+S marking provide
the best possible grip in wintry road condi-
tions.
Only these tires will allow driving safety sys-
tems such as ABS and ESP ®
to function opti-
mally in winter. These tires have been devel-
oped specifically for driving in snow.
For safe driving, use M+S tires of the same
make and tread pattern on all wheels.
Always observe the maximum permissible
speed specified for the M+S tires you have
mounted.
If you mount M+S tires that have a lower maxi-
mum permissible speed than the maximum
design speed of the vehicle, affix a corre-
sponding warning label in the driver's field of
vision. You can obtain this at a qualified spe-
cialist workshop.
Once you have mounted the winter tires:
X Check the tire pressure (Y page
282).
X Restart the tire pressure monitor
(Y page

288).280
Operation in winter
Wheels and tires

Snow chains
G
WARNING
If snow chains are installed to the front
wheels, they may drag against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tires.
There is a risk of an accident.
To avoid hazardous situations:
R never install snow chains to the front
wheels
R always install snow chains in pairs to the
rear wheels. G
WARNING
If you drive too fast with snow chains moun-
ted, they may snap. As a result, you could
injure others and damage the vehicle. There
is a risk of an accident.
Observe the maximum permissible speed for
operation with snow chains.
When driving with snow chains installed, do
not exceed the maximum permissible speed of
30 mph (50 km/h
). Observe the country-spe-
cific laws and regulations for operation with
snow chains.
! Check the snow chains for damage before
mounting them. Damaged or worn snow
chains may snap and damage the following
components:
R wheel
R wheel housing
R wheel suspension
For this reason, you must use only snow
chains that are free of defects. Observe the
manufacturer's mounting instructions.
! Vehicles with steel wheels:
if you mount
snow chains on steel wheels, you may dam-
age the hub caps. Remove the hub caps
from the relevant wheels before mounting
the snow chains.
Snow chains increase traction on roads in win-
try conditions.
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains or trac-
tion aids which have been approved for
Mercedes-Benz vehicles. The snow chains or traction aids must be of class U or meet the
SAE type U

specification.
Information about snow chains can be
obtained from any Mercedes-Benz Commercial
Van Center.
When mounting snow chains, please bear the
following points in mind:
R Snow chains cannot be mounted on all
wheel/tire combinations. When mounting
the snow chains, note the permissible tire
and snow chain dimensions. Observe the
restrictions on the use of snow chains under
"Wheel/tire combinations" (Y page 302).
R Mount snow chains only in pairs and only to
the rear wheels. Observe the manufacturer's
mounting instructions.
R Only use snow chains when the road is cov-
ered by a layer of snow. Remove the snow
chains as soon as possible when you come
to a road that is not snow-covered.
R The use of snow chains may be restricted by
local regulations. Observe the appropriate
regulations before mounting snow chains.
R When driving with snow chains installed, do
not exceed the maximum permissible speed
of 30 mph (50 km/h).
R Check the tension of the chains after a dis-
tance of approximately 0.5 miles (1.0 km)
and tighten the chains if required.
You may wish to deactivate ESP ®
when pulling
away with snow chains installed ( Y page 69).
This allows the wheels to spin in a controlled
manner, achieving an increased driving force
(cutting action). Operation in winter
