When you apply your brakes, the
Cruise Control shuts off.
A
CAUTION:
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.
To Set Cruise Control
Move the Cruise
Control switch to
ON.
A
CAUTION:
If you leave your cruise control switch on when you're not using
cruise, you might hit
a
button and go into cruise when you don't
want to. You could be startled and even lose control. Keep the
cruise control switch OFF until you want to use it.
Get up to the speed you want.
