NOTE
When the ignition is switched OFF, the
system status before it was turned off is
maintained. For example, if the ignition is
switched OFF with the cruise control
system operable, the system will be
operable when the ignition is switched ON
the next time.
▼To Set Speed
1. Activate the cruise control system by
pressing the ON switch. The cruise
main indication (wh ite) is displayed.
2. Accelerate to the desired speed, which must be more than 25 km/h (16 mph).
3. Set the cruise control by pressing the SET
switch at the desired speed. The
cruise control is set at the moment the
SET
switch is pressed. Release the
accelerator pedal simultaneously. The
cruise set indication (white) is
displayed and the cruise set indicator
light (green) turns on.
NOTE
The cruise control speed setting cannot
be performed under the following
conditions:
(Automatic transaxle)
The selector lever is in the P or N
position.
(Manual transaxle)
The shift lever is in the neutral
position.
The parking brake is applied.
Release the SET or RES/ switch at
the desired speed, otherwise the speed
will continue increasing while the RES/
switch is pressed and held, and
continue decreasing while the SET
switch is pressed and held (except when
the accelerator pedal is depressed).
On a steep grade, the vehicle may
momentarily slow down while
ascending, or speed up while
descending.
The cruise control will cancel if the
vehicle speed decreases below 21 km/h
(13 mph) when climbing a steep grade.
The cruise control may cancel at about
15 km/h (9 mph) below the preset speed
such as when climbing a long, steep
grade.
▼ To Increase Cruising Speed
Follow either of these procedures.
To increase speed using cruise control
switch
Press the RES/ switch and hold it. Your
vehicle will accelerate. Release the switch
at the desired speed.

Press the RES/
switch and release it
immediately to adjust the preset speed.
Multiple operations will increase the
preset speed according to the number of
times it is operated.

the accelerator to return to the set speed.
▼To Decrease Cruising Speed
Press the SET switch and hold it. The
vehicle will gradually slow.
Release the switch at the desired speed.

Press the SET
switch and release it
immediately to adjust the preset speed.
Multiple operations will decrease the
preset speed according to the number of

Decreasing speed with a single SET
switch operation
Instrument cluster display for vehicle
speed indicated in km/h: 1 km/h (0.6 mph)
Instrument cluster display for vehicle
speed indicated in mph: 1 mph (1.6 km/h)
▼ To Resume Cruising Speed at More
Than 25 km/h (16 mph)
If the cruise control system temporarily
canceled (such as applying the brake
pedal) and the system is still activated, the
most recent set speed will automatically
resume when the RES/
switch is pressed.
If vehicle speed is below 25 km/h (16
mph), increase the vehicle speed up to 25
km/h (16 mph) or more and press the RES/
switch.
▼ To Temporarily Cancel
To temporarily cancel the system, use one
of these methods:
Slightly depress the brake pedal.
(Manual transaxle)
Depress the clutch pedal.
Press the OFF/CAN switch.
If the RES/
switch is pressed when the
vehicle speed is 25 km/h (16 mph) or
higher, the system reverts to the previously
set speed.
NOTE
If any of the following conditions occur,
the cruise control system is temporarily
canceled.
The parking brake is applied.
(Automatic transaxle)
The selector lever is in the P or N
position.
(Manual transaxle)
