Driving Hints
44
The first 1000 km (600 miles)
Drive your vehicle at various speeds. Do not
use full throttle. Never allow the engine to
labour at low revs.
Make good use of all gears. Depress the
accelerator pedal a maximum of around three
quarters of the available pedal travel in all
gears and drive ranges.
Do not drive faster than three quarters of
maximum speed.
The information concerns the engine and
parts of the power train, e.g. the final drive.
Never coast with engine not running
Many units will then not function (e.g. brake
servo unit). Driving in this manner is a danger
to yourself and others.
Brake servo unit
With the engine not running the brake servo
unit is no longer effective once the brake
pedal has been depressed once or twice. The
braking effect is not reduced but substantially
greater foot pressure is necessary to stop the
vehicle.
Driving in mountainous terrain
Electrically driven fan: The fan cooling
capacity is not dependant on engine speed. It
is not necessary, therefore, when driving
uphill to shift down into a lower gear if the
vehicle can climb in a higher gear.
