the distance between your vehicle and
other vehicles.
- For safety reasons, the cruise control
should not be used in the city, in stop­
and-go traff ic, on twist ing roads and
when road conditions are poor (such as
ice, fog, gravel, heavy rain and hydro­
planing) -risk of accident .
- Turn off the cruise control temporarily
when entering turn lanes, highway exit
lanes or in construction zones.
- Please note that inadvertently "resting" your foot on the accelerator pedal causes
the cruise control not to brake. This is
because the cruise control is overridden

pass someone. The speed you saved earlier
will resume as soon as you release the acceler­
ator pedal.
