The more cautiously you treat your vehicle
during the break-in period, the more satisfied
you will be with its performance later
on. You should therefore observe the following
for the first 1000 miles (1500 km):
Drive at varying but moderate road and
engine speeds.
Do not drive faster than 150 mph
(240 km/h).
Break in new tires for the first
100 miles (160 km), therefore avoid
high-speed cornering. Do not exceed a
speed of 125 mph (200 km/h).
Do not drive at engine speeds above
4500 rpm.
Try to avoid heavy load on the engine
(driving at full throttle) and driving at
high engine speeds (maximum of 2 / 3
of top speed of each gear) during this
break-in period.
Avoid accelerating by kick-down.
Change gears in good time.
Do not attempt to slow the vehicle
down by shifting to a lower gear using
the gear selector lever.
Select positions 3, 2 or 1 only when
driving at moderate speeds (for hill
driving).
Select C as the preferred shift program
( page 173) for the first 1000 miles
1500 km).
After 1000 miles (1500 km), you may gradually
bring the vehicle up to full road and
engine speed.
All of the above instructions also apply
when driving the first 1000 miles
(1500 km) after the engine or the rear differential
has been replaced.
i
Always obey applicable speed limits.
