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 
1 000 miles (1 500 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 
maximum rpm in each gear).
Avoid accelerating by kickdown.
Do not attempt to slow the vehicle 
down by shifting to a lower gear using 
the gear selector lever.

driving).

speeds to the permissible maximum.
All of the above instructions, as may apply 
to your vehicle type, also apply when driv-
ing the first 1 000 miles (1 500 km) after 
the engine or the rear differential has been
