This is from the Xterra manual:

Avoid driving for long periods at constant
speed, either fast or slow, and do not run the
engine over 4,000 rpm. Do not accelerate at full throttle in any gear. Avoid quick starts. Avoid hard braking as much as possible. Do not tow a trailer for the first 500 miles (800 km). Your engine, axle or other parts could be damaged.

The question is, what does "Avoid driving for long periods at constant speed, either fast or slow" mean? It conveniently does not define a "long period", but it does define the rpms to stay below (4000). Who is going to define what that period is if there are any engine problems? Couldn't 200km be considered a long period? Again, it's not defined in the manual, so this argument cannot be won or lost from what the actual manual states. Every expert here can chime in, but what's going to count in an arbitration meeting?
