6.9 kPa to 1 psi; another metric unit for air
pressure is bar. There are 100 kilopascals
(kPa) to 1 bar.
Maximum load rating
The maximum load in kilograms and
pounds that can be carried by the tire.
Maximum loaded vehicle weight

489 Technical data
Fuels, coolants, lubricants etc.
In areas where carbon deposits may be en-
countered due to lack of availability of gas-
olines which contain these additives,
Mercedes-Benz recommends the use of
additives approved by us for use on
Mercedes-Benz vehicles. Refer to Factory
Approved Service Products Pamphlet for a
listing of approved product(s). Follow di-
rections on product label.
Do not blend other fuel additives with fuel.
This only results in unnecessary costs and
may be harmful to the engine operation.
Damage or malfunction resulting from
poor fuel quality or from blending addition-
al fuel additives other than those tested
and approved by us for use on
Mercedes-Benz vehicles listed in the Fac-
tory Approved Service Products pamphlet
are not covered by the Mercedes-Benz
Limited Warranty.
Fuel requirements
Gasoline engine
Use only premium unleaded gasoline
meeting ASTM standard D 439:

The octane number (posted at the
p um p) mu st b e 9 1 m i n. It is a n ave ra ge
of both the Research (R) Octane Num-
ber and the Motor (M) Octane Number:
(R+M) / 2). This is also known as the
ANTI-KNOCK INDEX.
Unleaded gasoline containing oxygenates
such as ethanol, IPA, IBA and TBA can be
used provided the ratio of any one of these
oxygenates to gasoline does not exceed
10%; MTBE must not exceed 15%.
The ratio of methanol to gasoline must not
exceed 3% plus additional cosolvents.
Using mixtures of ethanol and methanol is
not allowed. Gasohol, which contains 10%
ethanol and 90% unleaded gasoline, can be
used.These blends must also meet all other fuel
requirements, such as resistance to spark
knock, boiling range, vapor pressure, etc.
Diesel engine
Only use commercially available vehicular
diesel fuels No. 2 or No. 1 (ASTM D975
No.2-D or No.1-D).
To prevent malfunctions, diesel fuel with
better cold flow quality is offered in the
winter months. Check with your fuel
retailer.
!Do not fill the tank with gasoline. Do
not mix diesel fuel with gasoline or
kerosene. The fuel system and engine
will otherwise be damaged, which is
not covered by the Mercedes-Benz
Limited Warranty.
