performanc einthefuture.
R You should therefore driv eatvarying
vehicle and engine speed sfor th efirst
1000 miles (1500 km).
R Avoid heavy loads, e.g .driving at full
throttle, during this period.
R Change gearing ood time, before the
tachometer needle is 001Bof the way to the
red area of the tachometer.
R Do not manually shift to alower gear to
brake the vehicle.
R If possible, do not depress the accelerator
pedal past the point of resistance
(kickdown).
R Ideally ,for the first 1000 miles (1500 km),
drive in program E. After 1,000 miles (1,500 km), you can
increase the engine spee
