Driving

• Each time you press the RES/+ or –/SET button, the vehicle speed is increased or

decreased by about 1 mph or 1.6 km/h accordingly.

• If you keep the RES/+ or –/SET button pressed, the vehicle speed increases or

decreases until you release it. This speed is then set.

To cancel cruise control, do any of the following:
• Press the CANCEL button.
• Press the MAIN button.
• Depress the brake pedal.
The CRUISE CONTROL indicator goes off.

Resuming the prior set speed:
After cruise control has been canceled, you can still
resume the prior set speed by pressing the RES/+
button while driving at a speed of at least 25 mph (40
km/h) or more.

You cannot set or resume in the following situations:

•

When vehicle speed is less than 25 mph (40 km/h)

•

When the MAIN button is turned off.

At vehicle speeds of 22 mph (35 km/h) or less, cruise
control canceled automatically.

Driving

Adaptive Cruise Control (ACC)

Helps 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.

Adaptive Cruise Control (ACC)

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.

The radar sensor for ACC is shared with the collision
mitigation braking system

(CMBS

2 Collision Mitigation Braking System

(CMBS

) P. 471

WARNING

Improper use of ACC can lead to a crash.

Use ACC only when driving on
expressways or freeways and in good
weather conditions.

WARNING

ACC has limited braking capability.

When your vehicle speed drops below
22 mph (35 km/h), ACC will
automatically cancel and no longer will
apply your vehicle’s brakes.

Always be prepared to apply the brake
pedal when conditions require.

When to use

■

Vehicle speed for adaptive cruise control: Desired speed in a range above
roughly 25 mph (40 km/h) ~.

■

Gear position for ACC: In

(

2 or higher position.

The radar sensor is in the
lower bumper.

Be careful not to have
the radar sensor cover
strongly impacted.

The camera is
located behind the
rearview mirror.

How to activate the system

Adaptive Cruise Control (ACC)

You can read about handling information for the
camera equipped with this system.

2 Front Sensor Camera P. 524

When the MAIN button is pressed, ACC and Lane
Keeping Assist System (LKAS) are both turned on or
off.

ACC may not work properly under certain conditions.

2 ACC Conditions and Limitations P. 502

When not using ACC: Turn off adaptive cruise by
pressing the MAIN button. This also will turn off the
Lane Keeping Assist System (LKAS).

Do not use ACC under the following conditions:

•

On roads with heavy traffic or while driving in
continuous stop and go traffic.

•

On roads with sharp turns.

•

On roads with steep downhill sections, as the set
vehicle speed can be exceeded by coasting. In such
cases, ACC will not apply the brakes to maintain
the set speed.

•

On roads with toll collection facilities or other
objects between lanes of traffic, or in parking
areas, or facilities with drive through access.

When the engine speed slows down, try to
downshift.
When the engine speed goes up, try to upshift.
You can maintain the set speed if you change gear
within five seconds.

How to use

Press the MAIN button on
the steering wheel.

Driving

Take your foot off the pedal and press down the –/SET button when you reach the
desired speed. The moment you release the button, the set speed is fixed, and ACC
begins.

When ACC starts operating, the vehicle icon,
interval bars and set speed appear on the
driver information interface.

When you use ACC, Straight Driving Assist (a
feature of the Electric Power Steering system)
is activated.
By enabling the steering system to
automatically compensate for natural steering
pull, Straight Driving Assist makes it easier for
you to keep your vehicle in a straight line.

) may come on

after re-connecting the battery. Drive a short distance
at more than 12 mph (20 km/h). The indicators
should go off. If they do not, have your vehicle
checked by a dealer.

■

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.

2 To Set or Change Following-Interval P. 506

When a vehicle whose speed is slower than
your set speed is detected in front of you, your
vehicle starts to slow down.

■

When in Operation

When in Operation

If the vehicle detected ahead of you slows down
abruptly, or if another vehicle is detected cutting in
front of you, the beeper sounds and a message
appears on the driver information interface.

Depress the brake pedal, and keep an appropriate
interval from the vehicle ahead.

Driving

■

There is no vehicle ahead

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 traveling at
the set speed, ACC accelerates your vehicle to
the set speed, and then maintains it.

■

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.

When in Operation

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.

You can also set the system to beep when a vehicle in
front of you comes in and goes out of the ACC
detecting range. Change the ACC Forward Vehicle
Detect Beep setting.

2 Customized Features P. 124, 335

Limitations
You may need to use the brake to maintain a safe
interval when using ACC. Additionally, ACC may not
work properly under certain conditions.

• An abnormal tire condition is detected, or the tires are skidding.
• Driving on a mountainous road, or driving off road for extended periods.
• Abrupt steering wheel movement.
• When the ABS, VSA® or CMBS

is activated.

• When the ABS or VSA® system indicator comes on.
• When you manually apply the parking brake.
• When the detected vehicle within the ACC range is too close to your vehicle.
• The camera behind the rearview mirror, or the area around the camera, including

the windshield, gets dirty.

• When the Maximum Load Limit is exceeded.
• When passing through an enclosed space, such as tunnel.
• Ignoring shift down indication shown in the tachometer display will cancel the

ACC after about 10 seconds.

• The engine speed goes into the tachometer’s red zone.
• The engine speed goes to below 1,000 rpm.
• You shift into neutral temporarily when shifting into a higher or lower gear.
