Output inc reases can:
R Change the emission values.
R Lead tomalfunctions.
R Result in consequential damage.
The operating saf ety of the engine is not guaran‐

If th eve hicle's engine output is increased:
R Tyres, suspension, brake sy stem and engine
cooling sy stem must be adap tedto the
inc rease engine output.
R Vehicle must be recertified.
R Report changes in output tothe accident
