Cruise Control
Cruise Main Indication (White)/
Cruise Set Indication (Green)

The indication has two colors.
Cruise Main Indication (White)
The indication turns on (white) when the
cruise control system is activated.
Cruise Set Indication (Green)
The indication turns on (green) when a
cruising speed has been set.
Activation/Deactivation
To activate the system, press the ON
switch. The cruise main indication (white)
turns on.
To deactivate the system, press the OFF/
CANCEL switch.
The cruise main indication (white) turns
off.
WARNING
Always turn off the cruise control system
when it is not in use:
Leaving the cruise control system in an
activation-ready state while the cruise
control is not in use is dangerous as
the cruise control could unexpectedly
activate if the activation button is
accidentally pressed, and result in loss
of vehicle control and an accident.

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 (white) turns on.
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 (green) turns on.

NOTE
 


 The cruise control speed setting cannot
be performed under the following
conditions:
 


 The selector lever is in the P or N
position.
 


 The parking brake is applied. 



 Release the SET/ or RESUME/

(except when the accelerator pedal is
depressed).
 


 On a steep grade, the vehicle may
momentarily slow down while ascending
or speed up while descending.

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.

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 some other method besides the OFF/
CANCEL switch was used to cancel
cruising speed (such as applying the brake
pedal) and the system is still activated, the
most recent set speed will automatically
resume when the RESUME/
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
RESUME/
switch.
To Temporarily Cancel
To temporarily cancel the system, use one
of these methods:
 


 Slightly depress the brake pedal.



 Press the OFF/CANCEL switch.
If the RESUME/ 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.



 The selector lever is in the P or N
position.
 


 When the cruise control system is
temporarily canceled by even one of the
applicable cancel conditions, the speed
cannot be re-set.
 


 The cruise control cannot be cancelled
while driving in manual mode (selector
lever shifted from D to M position).
Therefore, engine braking will not be
applied even if the transaxle is shifted
down to a lower gear. If deceleration is
required, lower the set speed or depress
the brake pedal.

To Deactivate

(cruise set indication (green) turns on)
Long-press the OFF/CANCEL switch or
press the OFF/CANCEL switch 2 times.
When a cruising speed has not been set
(cruise main indication (white) turns on)
Press the OFF/CANCEL switch.
