New Car Break-In-When starting out with
your
new car,
you
should drive moderately for 10 to 15 minutes to allow time for the
engine, transmission, and rear axle to warm up. Speeds can then be
increased as shown below:
CAR SPEED-First 200 miles not to exceed 50 miles per hour.
Second 200 miles not to exceed 60 miles per hour.
Third 200 miles not to exceed 70 miles per hour.
After
your
ca~ has warmed up,
speed
should be increased gradually
to the maximums in the above schedule, held there for a short dis-
tance, then gradually decreased to a slower speed for a short distance.
Driving at
speeds
up to 50 miles per hour, even for distances greater
than the 200-mile period, will not
"break-in"
your car for sustained
high speed driving. Sustained high speed driving should not be
undertaken until the above schedule of maximum speeds (or its
equivalent) is completed.
NOTE: Brakes, too, need "breaking-In". Avoid fast stops during the first
few hundred miles.
