RunnIng-In
Your vehicle does not need an elaborate running-in procedure. But it will perform better
in the long run if you follow these guidelines:
Do not drive at any one constant speed, fast or slow, for the first 1000 km. Do not
make full-throttle starts. Avoid downshifting to brake or slow the vehicle.
During the first 1000 km, avoid using more than moderate acceleration in lower
gears and avoid vehicle speeds above 110 km/h.
Between the first 1000 km and 5000 km, heavy acceleration in lower gears can be
used. Vehicle speeds above 110 km/h should be limited to five minutes per use.
Avoid making hard stops for the first 350 km. During this time the new brake linings
are not yet broken in. Hard stops with new linings can mean premature wear and
earlier replacement. Follow this breaking-in guideline every time you get new brake
linings.
It is recommended that the new vehicle be driven for at least 1,500 km before towing.
If the vehicle must tow before this do not exceed 80 km/h. The same applies if the
vehicle is fitted with a new or reconditioned engine, transmission or rear axle.
REAR AxLE Run-In
If local statutory speed limits, road and traffic conditions permit driving the vehicle at its
top speed, observe this additional run-in procedure.
Before driving the vehicle at its top speed for an extended time (more than approximately
5 minutes), the rear axle drive needs some preparation to settle in for maximum load.
Observe the following points for the first 5,000 km:
During the first 1,000 km, avoid using more than moderate acceleration in lower
gears and avoid vehicle speeds above 110 km/h.
Between 1,000 km and 5,000 km, heavy acceleration in lower gears may be used.
Vehicle speeds over 110 km/h should be limited to 5 minutes per use.
BRAkES
The power assisted brakes fitted to the vehicle use vacuum from the engine when it
is running. Therefore, never let the vehicle run down hills with the engine off, or coast
after switching the engine off.
Position your seat so that you can push the brake pedal easily. Nothing should be under
the brake pedal which could limit pedal travel, for instance, poorly fitting floor mats.
Continuous or heavy use will shorten the life of the brake pads.
PoWER STEERIng
The power steering fitted to the vehicle has been designed to reduce steering effort.
Note Take care not to hold the steering wheel fully turned when stationary (for example,
when waiting before turning a corner) as this generates high operating temperatures
and pressures within the system.
If power steering is not working, due to the engine stalling for example, the vehicle
can still be steered. However, due to the much greater effort required to steer, it is
recommended that you have the problem fixed as soon as possible.
