Front Sensor Camera

Continued

Driving

Front Sensor Camera

The camera, used in systems such as LKAS, Road Departure Mitigation system, ACC, 
and CMBS

TM

, is designed to detect an object that triggers any of the systems to 

operate their 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 Honda 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.

Radar Sensor

Avoid strong impacts to the front grille.

For the CMBS

TM

 to work properly:

Always keep the front grille clean.

Never use chemical solvents or polishing powder for 
cleaning the front grille. Clean it with water or a mild 
detergent.

Do not put a sticker on the front grille or replace the 
front grille.

If you need the radar sensor to be repaired, or 
removed, or the front grille is strongly impacted, turn 
off the system by using the safety support switch and 
take your vehicle to a dealer.

Braking

Brake System

Use the parking brake to keep the vehicle stationary when parking.

To apply:

Depress the parking brake pedal down with 
your foot.

To release:
1.

Depress the brake pedal.

2.

Depress the parking brake.

■

Parking Brake

NOTICE

Release the parking brake fully before driving. The 
rear brakes and axle can be damaged if you drive 
with the parking brake applied.

If you start driving without fully releasing the parking 
brake, a buzzer sounds as a warning, and

Braking

u

Brake System

Driving

Your vehicle is equipped with disc brakes at all four wheels. A vacuum power assist 
helps reduce the effort needed on the brake pedal. The brake assist system increases 
the stopping force when you depress the brake pedal hard in an emergency 
situation. The anti-lock brake system (ABS) helps you retain steering control when 
braking very hard.

Foot Brake

1

Foot Brake

Check the brakes after driving through deep water, 
or if there is a buildup of road surface water. If 
necessary, dry the brakes by lightly depressing the 
pedal several times.

If you hear a continuous metallic friction sound when 
applying the brakes, this is caused by the brake wear 
indicator rubbing on the brake rotor and indicates 
that the brake pads need to be replaced. Have the 
vehicle checked by a dealer. If you hear only an 
occasional squeak or squeal when you initially apply 
the brake pedal, this may be normal and caused by 
high frequency vibration of the brake pads against 
the rotating brake disc.

Constantly using the brake pedal while going down a 
long hill builds up heat, which reduces the brake 
effectiveness. Apply engine braking by taking your 
foot off the accelerator pedal and downshifting to a 
lower gear.

Do not rest your foot on the brake pedal while 
driving, as it will lightly apply the brakes and cause 
them to lose effectiveness over time and reduce pad 
life. It will also confuse drivers behind you.

Braking

u

Anti-lock Brake System (ABS)

Driving

Anti-lock Brake System (ABS)

Helps prevent the wheels from locking up, and helps you retain steering control by 
pumping the brakes rapidly, much faster than you can.

The electronic brake distribution (EBD) system, which is part of the ABS, also 
balances the front-to-rear braking distribution according to vehicle loading.

You should never pump the brake pedal. Let the ABS work for you by always 
keeping firm, steady pressure on the brake pedal. This is sometimes referred to as 
“stomp and steer.”

■

ABS operation

The brake pedal may pulsate slightly when the ABS is working. Depress the brake 
pedal and keep holding the pedal firmly down. On dry pavement, you will need to 
press on the brake pedal very hard before the ABS activates. However, you may feel 
the ABS activate immediately if you are trying to stop on snow or ice.

ABS may activate when you depress the brake pedal when driving on:

•

Wet or snow covered roads.

•

Roads paved with stone.

•

Roads with uneven surfaces, such as potholes, cracks, manholes, etc.

When the vehicle speed goes under 6 mph (10 km/h), the ABS stops.

■

ABS

1

Anti-lock Brake System (ABS)

NOTICE

The ABS may not function correctly if you use a tire of 
the incorrect size or type.

If the 

ABS

 indicator comes on while driving, there 

may be a problem with the system.
While normal braking will not be affected, there is a 
possibility that the ABS will not be operating. Have 
your vehicle checked by a dealer immediately.

The ABS is not designed for the purpose of reducing 
the time or distance it takes for a vehicle to stop: It is 
designed to limit brake lockup which can lead to 
skidding and loss of steering control.

In the following cases, your vehicle may need more 
distance to stop than a vehicle without the ABS:

•

You are driving on rough or uneven road surfaces, 
such as gravel or snow.

•

The tires are equipped with tire chains.

The following may be observed with the ABS system:

•

Motor sounds coming from the engine 
compartment when the brakes are applied, or 
when system checks are being performed after the 
engine has been started and while the vehicle 
accelerates.

•

Brake pedal and/or the vehicle body vibration when 
ABS activates.
These vibrations and sounds are normal to ABS 
systems and are no cause for concern.

In extremely cold temperatures, the parking brake 
may freeze up if applied. If such temperatures are 
expected, do not apply the parking brake but, if 
parking on a slope, either turn the front wheels so 
they will contact the curb if the vehicle rolls down the 
slope or block the wheels to keep the vehicle from 
moving. If you do not take either precaution, the 
vehicle may roll unexpectedly, leading to a crash.

How the System Works

1

Cross Traffic Monitor

*

Cross Traffic Monitor may not detect or may delay 
alerting an approaching vehicle, or may alert without 
an approaching vehicle under the following 
conditions:

•

An obstacle, such as another vehicle and a wall, 
near your vehicle’s rear bumper, is blocking the 
radar sensor’s scope.

•

Your vehicle is moving at the speed of about 3 mph 
(5 km/h) or higher.

•

A vehicle is approaching at the speed other than 
between about 6 mph (10 km/h) and 16 mph 
(25 km/h).

•

The system picks up external interference such as 
other radar sensors from another vehicle or strong 
radio wave transmitted from a facility nearby.

•

Either corner of the rear bumper is covered with 
snow, ice, mud or dirt.

•

When there is bad weather.

•

Your vehicle is on an incline.

•

Your vehicle is tilted due to a heavy load in the rear.

•

Your vehicle is reversing towards a wall, a pole, a 
vehicle, and so on.

The rear bumper or the sensors have been improperly 
repaired or the rear bumper has been deformed. 
Have your vehicle checked by a dealer.

For proper operation, always keep the rear bumper 
corner area clean.
Do not cover the rear bumper corner area with labels 
or stickers of any kind.
