Cruise Control
Your vehicle may have cruise control.
0
(Off): This position
turns the system off.
I
With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your
foot
on the accelerator. This can really help on long
trips. Cruise control does not work at speeds below
about 25 mph (40 km/h).
If you apply your brakes, the cruise control will
disengage.
I
(On): This position activates the system.
- / - (Resume/Accelerate): Push the lever to this symbol
to make the vehicle accelerate or resume to a
previously set speed.
(Set): Press this button to set the speed.
Cruise control can be dangerous where
you can't drive safely at a steady speed.
So, don't use your cruise control on
winding roads or in heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
needless wheel spinning, and you could
lose control. Don't use cruise control on
slippery roads.
