Manual transmission models
Adaptive Cruise Control (ACC)
Helps to maintain a constant vehicle speed and a set following-interval behind a
vehicle detected ahead of yours, without you having to keep your foot on the brake
or the accelerator.
3WARNING
Improper use of ACC can lead to a crash.
When ACC slows your vehicle by applying the brakes, your vehicle’s brake lights will
illuminate.
Use ACC only when driving on motorways
and in good weather conditions.
When to use
The camera is
located behind
the rearview
mirror.
3WARNING
ACC has limited braking capability. When
your vehicle speed drops below 25 km/h (15
mph), ACC will automatically cancel and no
longer will apply your vehicle’s brakes.
Always be prepared to apply the brake
pedal when conditions require.
The radar sensor is
inside the front grille.
Important Reminder
As with any system, there are limits to ACC. Use the
brake pedal whenever necessary, and always keep a
safe interval between your vehicle and other vehicles.
■Vehicle speed for adaptive cruise control: Desired speed in a range above roughly
30 km/h (18 mph) ~
When the engine speed slows down, try to
downshift.
■Shift position for ACC: in (2 or higher position
When the engine speed goes up, try to upshift.
You can maintain the set speed if you change gear
within five seconds.

If the vehicle ahead of you slows down abruptly, or if
another vehicle cuts in front of you, the beeper
sounds and a message appears on the driver
information interface, and the head-up warning
lights* flash.
■ There is a vehicle ahead
ACC monitors if a vehicle ahead of you enters the ACC range. If a vehicle is detected
doing so, the ACC system maintains or decelerates your vehicle’s set speed in order
to keep the vehicle’s set following-interval from the vehicle ahead.

■ There is no vehicle ahead
1When in Operation
Your vehicle maintains the set speed without
having to keep your foot on the brake or
accelerator pedal.
If there previously was a vehicle detected
ahead that kept your vehicle from travelling at
the set speed, ACC accelerates your vehicle to
the set speed, and then maintains it.
Even if the interval between your vehicle and the
vehicle detected ahead is short, ACC may start
accelerating your vehicle under the following
circumstances:
• The vehicle ahead of you is going at almost the
same speed as, or faster than, your vehicle.
• A vehicle that cuts in front of you is going faster
than your vehicle, gradually increasing the interval
between the vehicles.
A vehicle icon with dotted-line
contour appears on the driver
information interface
You can also set the system to beep when a vehicle
detected in front of you comes in and goes out of the
ACC detecting range. Change the ACC Vehicle
Ahead Detected Beep setting.
■ When you depress the accelerator pedal
You can temporarily increase the vehicle speed. In this case, there is no audible or
visual alert even if a vehicle is in the ACC range.
ACC stays on unless you cancel it. Once you release the accelerator pedal, the
system resumes an appropriate speed for keeping the following-interval while a
vehicle ahead is within the ACC range.

1To Adjust the Vehicle Speed
To Adjust the Vehicle Speed
■
If a vehicle detected ahead is going at a speed slower
than your increased set speed, ACC may not
accelerate your vehicle. This is to maintain the set
interval between your vehicle and the vehicle ahead.
Increase or decrease the vehicle speed using the RES/+ or –/SET buttons on the
steering wheel.
To increase speed
When you depress the accelerator pedal and then
push and release the –/SET button, the current speed
of the vehicle is set.
To decrease speed
• Each time you press the RES/+ or –/SET button, the vehicle speed is increased or
decreased by about 1 km/h or 1 mph accordingly.
• If you keep the RES/+ or –/SET button pressed, the vehicle speed increases or
decreases by about 10 km/h or 10 mph accordingly.

1To Set or Change Following-interval
The higher your vehicle’s following-speed is, the longer the short, middle, long or
extra long following-interval becomes. See the following examples for your
reference.
The driver must in all circumstances preserve a
sufficient braking interval from the vehicle which
precedes it and be aware that minimum intervals or
times of spacing can be provided by the provisions of
the Motorway Code locally applicable and that it is
the driver’s responsibility to respect those laws.

Intelligent Adaptive Cruise Control Function
■
Provides an early prediction for a cut-in situation. The system detects that a vehicle
running in the adjacent slower lane has an intention to cut in front of you and
adjusts the speed of your vehicle in advance while ACC is activated.
■ How the system works
The radar sensor in the front grille detects
vehicles ahead of you including those in the
adjacent lane, and the camera behind the
rearview mirror detects the lane markings.
This system improves ACC’s following/tracking
property; it adjusts your vehicle speed in
advance predicting a situation that a vehicle
running in the adjacent slower lane catches up
with a slower vehicle ahead of it and changes
the lane to cut in front of you early.
Slow
Vehicle
When such a cut-in situation is predicted, your
vehicle speed decreases a little. When
detected, your vehicle speed decreases
according to the vehicle cutting in front of
you.
Cut-in
Vehicle
As the speed is adjusted by the system, the cut
in vehicle icon appears on the driver
information interface to indicate that the
system is activated.

1Intelligent Adaptive Cruise Control Function
■ How the system activates
When a vehicle cuts in front of you is going faster than the vehicle ahead of it, and
your vehicle is going faster than the cut-in vehicle (i.e., when you need to slow
down), ACC predicts the cutting-in and adjust your vehicle speed.
When traffic changes from right hand side to left
hand side, driving on a road where there is oncoming
traffic for some distance automatically switches the
lane to be detected from right to left.
The system activates when all the following conditions are met:
• When ACC is activated.
• When you are driving on a multi-lane road.
• When your vehicle speed is between about 80 km/h (50 mph) and about 180
km/h (112 mph).
Intelligent adaptive cruise control may not activate
under the following conditions:
• When the speed difference between the cut-in
vehicle and the vehicle ahead of it in the adjacent
lane is small
• When the speed difference between the cut-in
vehicle and your vehicle is small (i.e., when speed
adjustment is not required)
• When a vehicle simply cuts in front of your vehicle
with no vehicle ahead in the adjacent lane
• When a vehicle cuts in from a faster lane
• The vehicle is on a straight or slightly curved road.
• The turn signals are off.
• The brake pedal is not depressed.
• When a vehicle cuts in from a slower lane.
■ Intelligent adaptive cruise control on and off
You can turn the system on and off using the driver information interface.
