!Please compare the recommended tire in-
flation pressure for your vehicle with the tire in-
flation pressure on the yellow label located on
the spare wheel rim.
If the tire inflation pressure on the yellow label
on the spare wheel rim differs from the values
given in this Operator’s Manual, inflate the spare
wheel tire to the recommended tire inflation
pressure given on the yellow label on the spare
wheel rim.
iPlease note that the tire inflation pressure of
the Minispare tire differs from the tire inflation
pressure of the road tires.
Make sure the Minispare tire is inflated to
approximately 61 psi (4.2 bar).
iThe CLK 63 AMG does not have a spare
wheel. The CLK 63 AMG is equipped with
TIREFIT, see “Sealing tires with TIREFIT
(CLK 63 AMG only)” (

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 Ap-
proved Service Products pamphlet, or
contact an authorized Mercedes-Benz
Center.
Engine oil additives
Do not blend oil additives with engine oil.
They may damage the engine.
Damage or malfunctions resulting from
blending oil additives are not covered by
the Mercedes-Benz Limited Warranty.
Air conditioning refrigerant
R-134a (HFC) refrigerant and special PAG
lubricating oil are used in the air
conditioning system.
Never use R-12 (CFC) or mineral-based
lubricating oil. Otherwise damage to the
system will occur.
!Using engine oils and oil filters of specifica-
tion other than those expressly required for the
Maintenance System (U.S. vehicles. Canada ve-
hicles, depending on vehicle production date) or
FSS (Canada vehicles, depending on vehicle pro-
duction date), or changing of oil and oil filter at
change intervals longer than those called for by
the Maintenance System (U.S. vehicles. Canada
vehicles, depending on vehicle production date)
or FSS (Canada vehicles, depending on vehicle
production date) will result in engine or emission
control system damage not covered by the
Mercedes-Benz Limited Warranty. Please follow Maintenance System
(U.S. vehicles. Canada vehicles, depending on
vehicle production date) or FSS (Canada vehi-
cles, depending on vehicle production date)
recommendations for scheduled oil changes.
Failure to do so will result in engine or emission
control system damage not covered by the
Mercedes-Benz Limited Warranty.
