277 Operation
Tires and wheels
Rotate tires before the characteristic tire
wear pattern becomes visible (shoulder
wear on front tires and tread center wear
on rear tires).
Thoroughly clean the mounting face of
wheels and brake disks, i.e. the inner side
of the wheels/tires, during each rotation.
Check for and ensure proper tire inflation
pressure.
For information on wheel change, see “Flat
tire” (
page 348).
Warning!G
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
97 lb-ft (130 Nm).
Only use genuine Mercedes-Benz wheel
bolts specified for your vehicle’s rims.

278 Operation
Winter driving
Before the onset of winter, have your
vehicle 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 below freezing temperatures
(
page 382).
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. Not all M+S rated
tires provide special winter performance.
Make sure the tires you use show M+S and
the mountain/snowflake.marking on
the tire sidewall. These tires meet specific
snow traction performance requirements
of the Rubber Manufacturers Association
(RMA) and the Rubber Association of Can-
ada (RAC) and have been designed specif-
ically for use in snow conditions. Using
winter tires is the only way to achieve the
maximum effectiveness of the ABS and
ESP in winter operation.For safe handling, make sure that all
mounted winter tires 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
vehicle, you must place a notice to this
effect where it will be seen by the driver.
Such notices are available from your tire
dealer or from 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
longer suitable for winter operation.

279 Operation
Winter driving
Block heater (Canada only)
The engine is equipped with a block
heater.
The electrical cable may be installed at an
authorized Mercedes-Benz Light Truck
Center.
Snow chains
Snow chains should only be driven on
snow-covered roads at speeds not to
exceed 30 mph (50 km/h). Remove chains
as soon as possible when driving on roads
without snow.Please observe the following guidelines
when using snow chains:
Use of snow chains is not permissible
with all wheel/tire combinations.
Snow chains should only be used on
the rear wheels. Follow the manufac-
turer’s mounting instructions.
Only use snow chains that are
approved by Mercedes-Benz. Your
authorized Mercedes-Benz Light Truck
Center will be glad to advise you on this
subject.
Use of snow chains may be prohibited
depending on location. Always check
local and state laws before installing
snow chains.
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.
i
When driving with snow chains, you
may wish to deactivate the ESP
(
page 84) before setting the vehicle
in motion. This will improve the
vehicle’s traction.

Vehicle care
We have selected car-care products and
compiled recommendations which are
specially matched to our vehicles and
which always reflect the latest technology.
You can obtain Mercedes-Benz approved
car-care products at an authorized
Mercedes-Benz Light Truck Center.
Scratches, corrosive deposits, corrosion or
damage due to negligent or incorrect care
cannot always be removed or repaired with
the car-care products recommended here.
In such cases it is best to seek aid at an au-
thorized Mercedes-Benz Light Truck
Center.
The following topics deal with the cleaning
and care of your vehicle and give important
“how-to” information as well as references
to Mercedes-Benz approved car-care
products.Power washer
When using a power washer for cleaning
the vehicle, always observe manufactur-
er’s operating instructions.
Tar stains
Quickly remove tar stains before they dry
and become more difficult to remove. A tar
remover is recommended.Paintwork, painted body components
Mercedes-Benz approved Paint Care
should be applied when water drops on the
paint surface do not “bead up”, normally
every three to five months, depending on
climate and washing detergent used.
Mercedes-Benz approved Paint Cleaner
should be applied if the paint surface
shows signs of dirt embedding (i.e. loss of
gloss).
Do not apply any of these products or wax
if your vehicle is parked in the sun or if the
hood is still hot.
Use the appropriate MB-Touch-Up
Stick for quick and provisional repairs
of minor paint damage (i.e. chips from
stones, vehicle doors, etc.).
!
Never use a round nozzle to
power-wash tires. The intense jet of
water can result in damage to the tire.
Always replace a damaged tire.
Always keep the jet of water moving
across the surface. Do not aim directly
at electrical parts, electrical connec-
tors, sensors, seals, or other rubber
parts.

348 Practical hints
Flat tire
Preparing the vehicle
Park the vehicle as far as possible from
moving traffic on a hard surface.
Turn on the hazard warning flashers.
Turn the steering wheel so that the
front wheels are in a straight ahead
position.
Set the parking brake (page 57).
Move the gear selector lever toP.
Turn off the engine (page 58).
Have any passenger exit the vehicle at
a safe distance from the roadway.
Remove the vehicle tool kit
(
page 323) and the jack
(
page 324).
Remove the spare wheel from the
spare wheel mounting bracket
(
page 325).Information on spare wheel
When you replace the vehicle’s tires, you
can use the spare wheel as a regular wheel
if:
it is not more than six years old
rim and tire are the same model as the
regular wheels
Warning!G
For your safety, remove spare wheel from
the spare wheel mounting bracket before
undertaking any further steps.
Warning!G
If the spare tire is more than six years old or
is not the same model as the regular tires,
have the spare tire replaced with a new tire
at the nearest Mercedes-Benz Light Truck
Center.
Never operate the vehicle with more than
one spare tire.
Warning!G
G55AMG:
Vehicles with different tire dimensions on
the front and rear axle: rim and tire size of
spare wheel and normal wheel differ.
Handling will be adversely affected when the
spare wheel is used.
Do not exceed the maximum speed of
50 mph (80 km/h).

Rims and tires
Rims and tires
Use only tires and rims which have been
specifically developed for your vehicle and
tested and approved by Mercedes-Benz.
Other tires and rims can have detrimental
effects, such as:
Poor handling characteristics
Increased noise
Increased fuel consumption
!
Moreover, tires and rims not approved
by Mercedes-Benz may, under load,
exhibit dimensional variations and dif-
ferent tire deformation characteristics
that could cause them to come into
contact with the vehicle body or axle
parts. Damage to the tires or the vehi-
cle may be the result.
i
Further information on tires and rims is
available at any authorized
Mercedes-Benz Light Truck Center.
A placard with the recommended tire
inflation pressures is located on the
driver’s door B-pillar. Some vehicles
may have supplemental tire inflation
pressure information for driving at high
speeds (
page 261) or for vehicle
loads less than the maximum loaded
vehicle condition. If such information is
provided, it can be found on the placard
located on the inside of the fuel filler
flap. The tire inflation pressure should
be checked regularly and should only
be adjusted on cold tires. Follow tire
manufacturer’s maintenance recom-
mendation included with vehicle.
