Resuming a Set Speed
If the cruise control is set at a
desired speed and then the brakes
are applied, the cruise control is
disengaged without erasing the
set speed from memory.
Once the vehicle speed reaches
about 40 km/h (25 mph) or more,
press the +RES button on the
steering wheel. The vehicle returns
to the previous set speed and stays
there.
Increasing Speed While Using
Cruise Control
If the cruise control system is
already activated,
. Press and hold the +RES button
on the steering wheel until the
desired speed is reached, then
release it.
. To increase vehicle speed in
small amounts, press the +RES
button. Each time this is done,
the vehicle goes about 1.6 km/h
(1 mph) faster.
Reducing Speed While Using

then release it.
. To slow down in small amounts,
press the SET– button on the
steering wheel briefly. Each time

Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to
increase the vehicle speed. When
you take your foot off the pedal,
the vehicle will slow down to the
previous set cruise speed.
Using Cruise Control on Hills
How well the cruise control will work
on hills depends upon the vehicle
speed, load, and the steepness of
the hills. While going up steep hills,
you might have to step on the
accelerator pedal to maintain the
vehicle speed. While going downhill,
you might have to brake or shift to
a lower gear to keep the vehicle
speed down. When the brakes
are applied the cruise control is
disengaged.
