Cruise Control
Cruise control may not hold the set
speed when you are going up and
down hills. If your speed increases
going down a hill, use the brakes to
slow down. This will cancel cruise
control. To resume the set speed,
press the RESUME/accel button.
The CRUISE CONTROL indicator
on the instrument panel will come
back on.
When climbing a steep hill, the
automatic transmission may
downshift to hold the set speed.
