When the transmission is in 

(

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

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 or the 
protection of transmission system is necessary.
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

Driving

Front Sensor Camera

The camera, used in systems such as LKAS, RDM, ACC with LSF, Traffic Jam Assist, 
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 grille 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.

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.

■

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-interval from the 
vehicle ahead.

2 To Set or Change Following-Interval P. 412

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

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

Even if the interval 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 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 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 an appropriate speed for keeping the following-interval while a 
vehicle ahead is within the ACC with LSF range.

■

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-
