Overriding Reverse Braking Assist
There could be instances when unexpected
or unwanted braking occurs. Firmly pressing
the accelerator pedal or switching the feature
off overrides the system...
Principle of Operation
The traction control system helps avoid drive
wheel spin and loss of traction.
If your vehicle begins to slide, the system
applies the brakes to individual wheels and,
when needed, reduces engine power at the
same time...
