driving slowly, e.g. in mountainous terrain. After 1000 miles (1500 km), you can increase
the engine speed graduall
yand accelerate
the vehicle to full speed.
Additional breaking-in notes for AMG

R Do not drive faster than 85 mph
(140 km/h) for the first 1000 miles
(1500 km).
R Only allow the engine to reach amaximum
engine speed of 4500 rpm briefly.
