2012 MERCEDES-BENZ G-Class fuel

Engine oil
Please bear the following in mind The engine oils are matched to the
performance of Mercedes-Benz engines and
service intervals. For this reason, only use
engine
oils
and oil filters that are approved for
vehicles with a service system.
For a list of approved engine oils and oil filters,
consult an authorized Mercedes-Benz Center
or go to the Internet site
http://bevo.mercedes-benz.com (USA
only).
! Never use engine oil or an oil filter of a
specification other than is necessary to
fulfill the prescribed service intervals. Do
not change the engine oil or oil filter in
order to achieve longer replacement
intervals than those prescribed. You could
otherwise cause engine damage or damage
to the exhaust gas aftertreatment.
Follow the instructions in the service
interval display regarding the oil change.
Otherwise, you may damage the engine and
the exhaust gas aftertreatment.
The table shows which engine oils have been
approved for your vehicle. Model Engine

Additives !
Do not

use any additives in the engine oil.
This could damage the engine.
Engine oil viscosity Viscosity describes the flow characteristics
of
a

fluid. If an engine oil has a high viscosity, this means that it is thick; a low viscosity
means that it is thin.
Select an engine oil with an SAE (viscosity)
classification suitable for the prevailing
outside temperatures. The following table
shows the correct SAE classification to be
used.
The

low-temperature characteristics of
engine oils can deteriorate significantly, e.g.
as a result of aging, soot and fuel deposits. It
is therefore strongly recommended that you
carry out regular oil changes using an
approved engine oil with the appropriate SAE
classification. Refrigerant of the air-conditioning
system
The air-conditioning system is filled with
R134a (HFC) refrigerant and a special PAG
lubricant.
! Never use refrigerant R 12 (CFC) or
mineral lubricants. Otherwise, you could
damage the air-conditioning system. Brake fluid
G
WARNING
The brake fluid constantly absorbs moisture
from the air; this lowers its boiling point.
If the

boiling point of the brake fluid is too low,
vapor pockets may form in the brake system
when the brakes are applied hard (e.g. when
driving downhill). This would impair braking
efficiency. Service products and capacities
