Engine oils
Engine oils are specifically tested for
their suitability in our engines and dura-
bility for our service intervals. There-
fore, only use engine oils and oil filters
required for vehicles with the Mainte-
nance System. For a listing of approved
engine oils and oil filters contact an
authorized smart center.
!
Using engine oils and oil filters of
specification other than those expressly
required for the Maintenance System, or
changing of oil and oil filter at change
intervals longer than those called for by
the Maintenance System will result in
engine or emission control system dam-
age not covered by the smart Limited
Warranty.
Please follow Maintenance System rec-
ommendations for scheduled oil changes.
Failure to do so will result in engine or
emission control system damage not cov-
ered by the smart Limited Warranty.
Viscosity grades for engine oils

according to the lowest air temperature
