To Resume a Sef Speed
Suppose you set your Cruise Control at a desired speed and then you apply
the brake. This, of course, shuts off the Cruise Control. But you don't need
to reset it.
Once you're going
about 25 mph
(40 k d h ) or more,
you can move the
Cruise Control switch
from ON to WA
(Resume/Accelerate)
for about half a
second.
You'll go right back up to your chosen speed and stay there.
Remember, if you hold the switch at R/A longer than half a second, the
vehicle will keep going faster until you release the switch or apply the
brake. You could be startled and even lose control. So unless you want to go
faster, don't hold the switch
at WA.
To Increase Speed While Using Cruise Control
There are two ways to go to a higher speed. Here's the first:
Use the accelerator pedal to get to the higher speed.
Push the button at
the end of the
lever, then release
the button and the
accelerator pedal.
You'll now cruise
at the higher
speed.
