222 OperationThe first 1 000 miles (1 500 km)In the “Operation” section you will find de-
tailed information on operating, maintain-
ing and caring for your vehicle.
The first 1 000 miles (1 500 km)The more cautiously you treat your vehicle
during the break-in period, the more satis-
fied you will be with its performance later
on.
Drive your vehicle during the first
1000 miles (1500 km) at varying but
moderate vehicle and engine speeds.
During this period, avoid heavy loads
(full throttle driving) and excessive en-
gine speeds (no more than 2/3 of max-
imum rpm in each gear).
Avoid accelerating by kick-down.
Do not attempt to slow the vehicle
down by shifting to a lower gear using
the selector lever.
Select positions3, 2 or1 only when
driving at moderate speeds (for hill
driving).
After 1 000 miles (1 500 km) you may
gradually increase vehicle and engine
speeds to the permissible maximum.
!All of the above, as may apply to your
vehicle type, also apply when driving
the first 1 000 miles (1 500 km) after
the engine or the rear differential has
been replaced.iAlways obey applicable speed limits.
