Other information:
The Electronic Stability Control
(ESC) system helps to stabilize the
vehicle during cornering manoeuvres.
ESC checks where you are steering
and where the vehicle is actually
going. ESC applies braking pressure
to any one of the vehicle's brakes
and intervenes in the engine management
system to assist the driver
with keeping the vehicle on the
intended path...
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tyre
life and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tyre
wear or your vehicle pulling one way
or the other, the alignment may need
to be reset...
