2005 MERCEDES-BENZ G55AMG service interval

12 IntroductionOperator’s ManualMaintenance
The Maintenance Booklet describes all the
necessary maintenance work which should
be performed at regular intervals.
Always have the Maintenance Booklet with
you when you take the vehicle to your au-
thorized Mercedes-Benz Light Truck
Center for service. The service advisor will
record each service in the booklet for you.
Roadside Assistance
The Mercedes-Benz Roadside Assistance
Program provides factory-trained technical
help in the event of a breakdown. Calls to
the toll-free Roadside Assistance number
1-800-FOR-MERCedes (in the USA)
1-800-387-0100 (in Canada)
will be answered by Mercedes-Benz
Customer Assistance Representatives
24 hours a day, 365 days a year.
Roadside Assistance will be provided in ac-
cordance with standard program guide-
lines which include providing service to the
vehicle up to a reasonable distance from a
paved roadway. We will make every effort
to assist in a breakdown situation, howev-
er, the accessibility of your vehicle will be
determined by our authorized
Mercedes-Benz Light Truck Center techni-
cian or the tow service provider on a case
by case basis and may be a factor in our
ability to respond.Additional charges may be applicable for a
breakdown location determined not to be a
reasonably accessible roadside location as
determined by our authorized technician
and tow service provider.
For additional information refer to the
Mercedes-Benz Roadside Assistance
Program Brochure in your vehicle literature
portfolio.

216 OperationDriving instructionsDrive sensibly – save fuel
Fuel consumption, to a great extent, de-
pends on driving habits and operating
conditions.
To save fuel you should:

Keep tires at the recommended infla-
tion pressures.


Remove unnecessary loads.


Allow engine to warm up under low
load use.


Avoid frequent acceleration and decel-
eration.


Have all maintenance work performed
at the intervals specified in the
Maintenance Booklet and as required
by the maintenance service display.
Contact an authorized Mercedes-Benz
Light Truck Center.
Fuel consumption is also increased by driv-
ing in cold weather, in stop-and-go traffic,
on short trips and in hilly area.
Drinking and driving
Pedals
Warning!
G
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 judgement.
The possibility of a serious or even fatal ac-
cident are greatly increased when you drink
or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.
Warning!
G
Keep driver’s foot area clear at all times. Ob-
jects stored in this area may impair pedal
movement.

243 Operation
Engine compartment
Adding engine oil
Only use approved engine oils and oil fil-
ters required for vehicles with
Maintenance System (U.S. vehicles) or
FSS (Canada vehicles). For a listing of ap-
proved engine oils and oil filters, refer to
the Factory Approved Service Products
pamphlet in your vehicle literature portfo-
lio, or contact an authorized
Mercedes-Benz Light Truck Center.
Using engine oils and oil filters of specifica-
tion other than those expressly required
for the Maintenance System (U.S. vehi-
cles) or FSS (Canada vehicles), or changing
of oil and oil filter at change intervals long-
er than those called for by the
Maintenance System (U.S. vehicles) or
FSS (Canada vehicles) will result in engine
damage not covered by the
Mercedes-Benz Limited Warranty.

277 Operation
Maintenance
Maintenance
In the “Operation” section you will find de-
tailed information on operating, maintain-
ing, and caring for your vehicle.
We strongly recommend that you have
your vehicle serviced by an authorized
Mercedes-Benz Light Truck Center, in ac-
cordance with the Maintenance Booklet at
the times called for by the maintenance
service indicator display.
Failure to have the vehicle maintained in
accordance with the Maintenance Booklet
and maintenance service indicator at the
designated times/mileage will result in ve-
hicle damage not covered by the
Mercedes-Benz Limited Warranty.
The maintenance service indicator will
notify you when your next maintenance
service is due.Starting approximately one month before
maintenance service is due, one of the fol-
lowing messages will appear in the multi-
function display while you are driving or
when you switch on the ignition (example
service A):
SERVICE A IN XX DAYS
SERVICE A IN XX MILES (KM)
SERVICE A DUE NOW!The type of maintenance service due is in-
dicated in the speedometer display field:
9Basic service (A)
½Extended service (B)
iVehicles equipped with FSS (F
lexible
S
ervice S
ystem) only (Canada
vehicles): The interval between mainte-
nance services depends on your driving
habits. A gentle driving style, moderate
engine speeds and the avoidance of
short-distance trips will lengthen the
interval between maintenance
services.

Engine oils
Engine oils are specifically tested for their
suitability in our engines and durability for
our service intervals. Therefore, only use
approved engine oils and oil filters re-
quired for vehicles with Maintenance
System (U.S. vehicles) or FSS (Canada
vehicles). For a listing of approved engine
oils and oil filters, refer to the Factory
Approved Service Products pamphlet, or
contact an authorized Mercedes-Benz
Light Truck Center.Using engine oils and oil filters of specifica-
tion other than those expressly required
for the Maintenance System (U.S. vehi-
cles) or FSS (Canada vehicles), or changing
of oil and oil filter at change intervals
longer than those called for by the
Maintenance System (U.S. vehicles) or
FSS (Canada vehicles) will result in engine
damage not covered by the
Mercedes-Benz Limited Warranty.Please follow Maintenance System (U.S.
vehicles) or FSS (Canada vehicles) recom-
mendations for scheduled oil changes.
Failure to do so will result in engine dam-
age not covered by the Mercedes-Benz
Limited Warranty.

378 Technical dataFuels, coolants, lubricants, etc.Coolants
The engine coolant is a mixture of water
and anticorrosion / antifreeze, which pro-
vides:

Corrosion protection


Freeze protection


Boiling protection (by increasing the
boiling point)
The cooling system was filled at the factory
with a coolant providing freeze protection
to approximately -35°F (-37°C) and corro-
sion protection.
If the antifreeze mixture is effective to
-22°F (-30°C), the boiling point of the cool-
ant in the pressurized cooling system is
reached at approximately 266°F (130°C).
The coolant solution must be used year
round to provide the necessary corrosion
protection and increase boil-over protec-
tion. Refer to Maintenance Booklet for
replacement interval.Coolant system design and coolant used
determine the replacement interval. The
replacement interval published in the
Maintenance Booklet is only applicable if
MB 325.0 anticorrosion/antifreeze solu-
tion or other Mercedes-Benz approved
products of equal specification (see
Factory Approved Service Products
pamphlet) are used to renew the coolant
concentration or bring it back up to the
proper level.
To provide important corrosion protection,
the solution must be at least 45% anticor-
rosion/antifreeze (equivalent to freeze
protection to approx. - 22°F [-30°C]).
If you use a solution that is more than 55%
anticorrosion/antifreeze (freeze protec-
tion to approx. - 49°F [-45°C]), the engine
temperature will increase due to the lower
heat transfer capability of the solution.
Therefore, do not use more than this
amount of anticorrosion/antifreeze.If the coolant level is low, water and MB
anticorrosion /antifreeze should be used
to bring it up to the proper level (have cool-
ing system checked for signs of leakage).
Please make sure the mixture is in accor-
dance with label instructions.
The water in the cooling system must meet
minimum requirements, which are usually
satisfied by normal drinking water. If you
are not sure about the water quality, con-
sult an authorized Mercedes-Benz Light
Truck Center.
