192 OperationThe first 1000 miles (1500 km)
In the “Operation” section you will find de-
tailed information on operating, maintain-
ing and caring for your vehicle.
The first 1000 miles (1500 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 gear selector lever.
Select positions3, 2 or1 only when
driving at moderate speeds (for hill
driving).After 1000 miles (1500 km) you may grad-
ually increase vehicle and engine speeds
to the permissible maximum.
All of the above instructions, as may apply
to your vehicle type, also apply when the
first 1000 miles (1500 km) after the en-
gine, the transfer case, the front differen-
tial or the rear differential has been
replaced.
iAlways obey applicable speed limits.
