160 Controls in detailLoadingLoading instructions
The gross vehicle weight which is the
weight of the vehicle including fuel, tools,
spare wheel, installed accessories, pas-
sengers and luggage / cargo must never
exceed the Gross Vehicle Weight Rating
(GVWR) for your vehicle. In addition, the
load must be distributed in such a way so
that the weight on each axle never exceeds
the Gross Axle Weight Rating (GAWR) for
the front and rear axle. The GVWR and
GAWR for your vehicle are indicated on the
certification label which can be found on
the left door pillar.The handling characteristics of a fully load-
ed vehicle depend greatly on the load dis-
tribution. It is therefore recommended to
load the vehicle according to the illustra-
tions shown, with the heaviest items being
placed towards the front of the vehicle.
Please pay attention to and comply with
the following instructions when loading the
vehicle and transporting cargo:


Always place items being carried
against front or rear seat backrests,
and fasten them as securely as possi-
ble.


The heaviest portion of the cargo
should always be kept as low as possi-
ble against front or rear seat backrests.
Warning!
G
Always fasten items being carried as secure-
ly as possible using cargo tie-down rings and
fastening materials appropriate for the
weight and size of the load.
In an accident, during hard braking or sud-
den maneuvers, loose items will be thrown
around inside the vehicle, and can cause in-
jury to vehicle occupants unless the items
are securely fastened in the vehicle.
To help avoid personal injury during a colli-
sion or sudden maneuver, always use parti-
tion net when transporting cargo.
Never drive vehicle with the liftgate open.
Deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in uncon-
sciousness and death.

212 OperationDriving instructionsElectrical connections
The vehicle is prewired to accept the sev-
en-wire harness included in the
Mercedes-Benz approved trailer hitch re-
ceiver kit.
An additional four-pole conversion plug is
included in the Mercedes-Benz supplied
trailer hitch receiver kit.
For further information, see an authorized
Mercedes-Benz Light Truck Center.Vehicle and trailer weights and ratings
Gross Vehicle Weight Rating (GVWR) is the
maximum permissible vehicle weight:
6614 lbs (3000 kg).
Gross Vehicle Weight (GVW):
Comprises weight of vehicle including fuel,
tools, spare wheel, installed accessories,
passengers, cargo and trailer tongue. It
must never exceed the GVWR.
Gross Axle Weight Rating (GAWR) is the
maximum permissible axle weight:
Gross Trailer Weight (GTW) is the maxi-
mum permissible trailer weight to be
towed:
5000 lbs (2260 kg).
Trailer Tongue Weight Rating (TWR) is the
maximum permissible weight on the trailer
tongue:
500 lbs (225 kg) limit for Mercedes-Benz
approved hitch receiver.Loading a trailer


When loading a trailer, you should ob-
serve that neither the permissible GTW,
nor the GVWR are exceeded.
Maximum permissible values are listed
on the safety compliance certification
labels for the vehicle and for the trailer
to be towed.
The lowest value listed must be select-
ed when determining how the vehicle
and trailer are loaded.


The tongue weight at the hitch ball
must be added to the GVW to prevent
exceeding your Mercedes-Benz tow
vehicle’s rear GAWR.

iWe recommend loading the trailer in
such a manner that it has a tongue
weight (TW) between 10% and 15% of
the GTW.

232 OperationTires and wheelsLife of tire
The service life of a tire is dependent upon
varying factors including but not limited to:

Driving style


Tire pressure


Distance driven
Direction of rotation
Unidirectional tires offer added advantag-
es, such as better hydroplaning perfor-
mance. To benefit, however, you must
make sure the tires rotate in the direction
specified.
An arrow on the sidewall indicates the
intended direction of rotation of the tire.
Checking tire inflation pressure
Correct the tire pressure only when tires
are cold.
Regularly check your tire pressure at inter-
vals of no more than 14 days.
If the tires are warm, you should only
correct the tire pressure if it is too low for
current operating conditions.
A table on the fuel filler flap lists the
specified tire inflation pressures for warm
and cold tires as well as for various
operating conditions.
!When the wheels are heavily soiled,
e.g. after driving through mud, clean
the inside of the wheels with a jet of
water.Warning!
G
Tires and spare tire should be replaced after
six years, regardless of the remaining tread.
!Keep unmounted tires in a cool, dry
place with as little exposure to light as
possible. Protect tires from contact
with oil, grease and gasoline.
Warning!
G
If the tire pressure drops repeatedly:

Check the tires for punctures from
foreign objects.


Check to see whether air is leaking from
the valves or from around the rim.

233 Operation
Tires and wheels
Tire pressure changes by approximately
1.5 psi (0.1 bar) per 18°F (10°C) of air
temperature change. Keep this in mind
when checking tire pressure where the
temperature is different from the outside
temperature.
Tire temperature and tire pressure are also
increased while driving, depending on the
driving speed and the tire load.Check the spare tire periodically for condi-
tion and inflation. Spare tire will age and
b e c o m e w o r n o v e r t i m e e v e n i f n e v e r u s e d ,
and thus should be inspected and replaced
when necessary.
Rotating wheels
The wheels can be rotated every 3000 to
6000 miles (5 000 to 10 000 km) or soon-
er if necessary, according to the degree of
tire wear. The same direction of tire rota-
tion must be retained.
Rotate the wheels before the characteris-
tic tire wear pattern becomes visible
(shoulder wear on front wheels and tread
center wear on rear wheels).
Thoroughly clean the inner side of the
wheels after each rotation. Check and
make sure proper tire inflation pressure.
iThe pressures listed for light loads are
minimum values offering high driving
comfort.
Increased inflation pressures listed for
heavier loads may also be used for light
loads. These higher pressures produce
favorable handling characteristics. The
ride of the vehicle, however, will be
somewhat harder. Never exceed the
max. values or inflate tires below the
min. values listed in the fuel filler flap.
Warning!
G
Follow recommended inflation pressures.
Do not overinflate tires. Overinflated tires
can result in sudden deflation (blowout)
because they are more likely to become
punctured or damaged by road debris,
potholes, etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
Do not overload the tires by exceeding the
Gross Vehicle Weight Rating (GVWR) and
the Gross Axle Weight Rating (GAWR) as
indicated on the certification label on the
driver’s door pillar. Overloading the tires can
overheat them, possibly causing a blowout.
Warning!
G
Rotate front and rear wheels only if they are
of the same size,

235 Operation
Winter driving
Winter driving
Before the onset of winter, have your vehi-
cle winterized at an authorized
Mercedes-Benz Light Truck Center. This
service includes:

Check of anticorrosion and antifreeze
concentration.


Addition of cleaning concentrate to the
water of the windshield and headlamp
cleaning system. Add MB Concentrate
“S” to a premixed windshield washer
solvent / antifreeze which is formulated
for temperatures below freezing point
(page 319).


Battery test. Battery capacity drops
with decreasing ambient temperature.
A well charged battery helps to make
sure that the engine can be started
even at low ambient temperatures.


Tire change. Mercedes-Benz recom-
mends M+S rated radial-ply tires with a
minimum tread depth of approximately 1/6in (4 mm) on all four wheels for the
winter season.
Winter tires
Always use winter tires at temperatures
below 45°F (7°C) and whenever wintry
road conditions prevail. Use of winter tires
is the only way to achieve the maximum ef-
fectiveness of the ABS, ESP, 4-ETS, and
EBP in winter operation.
For safe handling, make sure all winter
tires mounted are of the same make and
have the same tread design.Always observe the speed rating of the
winter tires installed on your vehicle. If the
maximum speed for which your tires are
rated is below the speed rating of your ve-
hicle, you must place a notice to this effect
where it will be seen by the driver. Such no-
tices are available at your tire dealer or any
authorized Mercedes-Benz Light Truck
Center.Warning!
G
Winter tires with a tread depth under
1/6in
(4 mm) must be replaced. They are no long-
er suitable for winter operation.
Warning!
G
If you use your spare tire when winter tires
are fitted on the other wheels, be aware that
the difference in tire characteristics may
very well impair turning stability and that
overall driving stability may be reduced.
Adapt your driving style accordingly.
Have the spare tire replaced with a winter
tire at the nearest authorized
Mercedes-Benz Light Truck Center.

266 Practical hintsWhere will I find ...?Spare wheel (space-saver tire)
Use the spare wheel only temporarily,
while observing the following restrictions:

Do not exceed vehicle speed of
50 mph (80 km / h).
