D:

The vehicle will go into the sequential mode momentarily, and the sequential mode 
gear selection indicator will come on.
Once you start traveling at a constant speed, the sequential mode will automatically 
switch off, and the sequential mode gear selection indicator will go off.

Hold the

The vehicle will go into the sequential mode, and the M (sequential mode) indicator 
and sequential mode gear selection indicator will come on.
If the vehicle speed increases and the engine speed reaches near the tachometer’s 
red zone, the transmission automatically shifts up to 7th.
You can cancel this mode by pressing the SPORT button, or pulling the

Sequential Mode Operation

Each paddle shift operation makes a single gear 
change.
To change gears continuously, release the paddle 
shifter before pulling it again for the next gear.

If the sequential mode gear selection indicator blinks 
when you try to shift up or down, this means your 
vehicle speed is not in its allowable gear range.
Slightly accelerate to shift up and decelerate to shift 
down while the indicator is blinking.

In SPORT mode, to prioritize the engine performance 
enhancement, the transmission may not allow for 
shifting up while the engine speed is low.

Reactive Force Pedal

Driving

Reactive Force Pedal

The system increases the accelerator pedal 
resistance force when you depress the 
accelerator pedal. This gives you the feeling 
that the vehicle's acceleration is in response to 
your pedal operation.

At the same time, a slight increase in the accelerator pedal resistance force helps to 
modify your driving style to be in an efficient manner especially when you apply 
more force to the pedal than is necessary.

The Reactive Force Pedal is designed also to help prevent your wheels from possibly 
spinning out due to excessive throttle, and help make the vehicle start smoothly 
when roads are slippery due to ice, snow, excessive rainfall, etc.

1

Reactive Force Pedal

The Reactive Force Pedal system in no way restricts or 
limits your ability to operate the accelerator pedal to 
accelerate the vehicle.

If the Collision Mitigation Braking System

TM

 (CMBS

TM

) 

detects a possible collision, you may feel an opposing 
force from the accelerator pedal.

Front Sensor Camera

Continued

Driving

Front Sensor Camera

The camera, used in systems such as LKAS, RDM, ACC with LSF, and CMBS

TM

, is 

designed to detect an object that triggers any of the systems to operate its 
functions.

This camera is located behind the rearview 
mirror.

To help reduce the likelihood that high interior 
temperatures will cause the camera’s sensing 
system to shut off, when parking, find a shady 
area or face the front of the vehicle away from 
the sun. If you use a reflective sun shade, do 
not allow it to cover the camera housing. 
Covering the camera can concentrate heat on 
it.

■

Camera Location and Handling Tips

1

Front Sensor Camera

Never apply a film or attach any objects to the 
windshield, the hood, or the front grill that could 
obstruct the camera's field of vision and cause the 
system to operate abnormally.
Scratches, nicks, and other damage to the windshield 
within the camera’s field of vision can cause the 
system to operate abnormally. If this occurs, we 
recommend that you replace the windshield with a 
genuine Acura replacement windshield. Making even 
minor repairs within the camera’s field of vision or 
installing an aftermarket replacement windshield 
may also cause the system to operate abnormally.
After replacing the windshield, have a dealer 
recalibrate the camera. Proper calibration of the 
camera is necessary for the system to operate 
properly.

Do not place an object on the top of the instrument 
panel. It may reflect onto the windshield and prevent 
the system from detecting lane lines properly.

•

Use the climate control system to cool down the 
interior and, if necessary, also use defroster mode 
with the airflow directed towards the camera.

•

Start driving the vehicle to lower the windshield 
temperature, which cools down the area around 
the camera.

If the Some Driver Assist Systems Cannot 
Operate: Clean Front Windshield message 
appears:

•

Park your vehicle in a safe place, and clean the 
windshield. If the message does not disappear after 
you have cleaned the windshield and driven for a 
while, have your vehicle checked by a dealer.

Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)

Continued

Driving

Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)

Helps maintain a constant vehicle speed and a set following-interval behind a vehicle 
detected ahead of yours and, if the detected vehicle slows to a stop, decelerates and 
stops your vehicle, without you having to keep your foot on the brake or the 
accelerator.
When ACC with LSF slows your vehicle by applying the brakes, your vehicle's brake 
lights will illuminate.

There is a vehicle ahead

ACC with LSF monitors if a vehicle ahead of you enters the ACC with LSF range. If a 
vehicle is detected doing so, the ACC with LSF system maintains or decelerates your 
vehicle’s set speed in order to keep the vehicle’s set following-distance from the 
vehicle ahead.

2 To Set or Change Following-Distance P. 391

When a vehicle whose speed is slower than 
your set speed comes in or cuts in front of you 
and is detected by the radar, your vehicle 
starts to slow down.

■

When in Operation

1

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, a message appears on the multi-information 
display, and the head-up warning lights come on.
Depress the brake pedal, and keep an appropriate 
distance from the vehicle ahead.

Even if the distance between your vehicle and the 
vehicle detected ahead is short, ACC with LSF 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 distance 
between the vehicles.

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

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 with LSF 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 with LSF range.
ACC with LSF stays on unless you cancel it. Once you release the accelerator pedal, 
the system resumes the set speed.
There are times when the vehicle speed will decrease when the accelerator pedal is 
lightly applied.

■

A vehicle detected ahead is within ACC with LSF range and slows to a stop

Your vehicle also stops, automatically. The 
Stopped message appears on the multi-
