Automatic shutoff

CMBS

 indicator comes and stays 

on when:

•

The temperature inside the system is high.

•

You drive off-road or on a mountain road, or curved and winding road for an

Adaptive Cruise Control (ACC)

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.

ACC cannot be activated if Intelligent Traction 
Management setting is snow, sand

WARNING

Improper use of ACC can lead to a crash.
Use ACC only when driving on expressways 
or freeways and in good road and weather 
conditions.

3

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.

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.

For directions on the proper handling of the radar 
sensor, refer to the following page.

ACC Conditions and Limitations

 P. 443

When not using ACC: Turn off adaptive cruise by 
pressing the 

MAIN

 button. This also will turn off the 

Lane Keeping Assist System (LKAS).

When the 

MAIN

 button is pressed, both ACC and 

the Lane Keeping Assist System (LKAS) are either 
turned on or off.

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.

You can switch the displayed set speed 
measurements on the audio/information screen 
between mph and km/h.

Adaptive Cruise Control (ACC)

Driving

■

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.

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 multi-information display.

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

Adaptive Cruise Control (ACC)

442

Driving

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

■

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.

1

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. A vehicle detect beep on and off can 
be selected.

You may need to use the brake to maintain a safe 
interval when using ACC. Additionally, ACC may not

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.

You can set the vehicle speed using the
