Allow the engine to warm up under low
load use. Do not place full load on the
engine until the operating temperature has
been reached.
Avoid spinning of a drive wheel for an
extended period when driving off on
slippery road surfaces.
This may cause serious damage to the
engine and the drivetrain which is not
covered by the Mercedes-Benz Limited
Warranty.
i During the brief warm-up, transmission
upshifting is delayed. This allows the
catalytic converter (gasoline engine) or
oxidation catalyst (diesel engine) to heat up
more quickly to operating temperature. Gear selector lever
