uuWhen DrivinguForward Collision Warning (FCW)
Driving
FCW may not activate or may not detect a vehicle in front of your vehicle, and may activate even when you are aware of a vehicle ahead
of you, or when there is no vehicle ahead under the following conditions.■FCW Limitations
Condition
●The distance between your vehicle and the vehicle ahead of you is too short.●A vehicle cuts in front of you at a slow speed, and it brakes suddenly.●A vehicle suddenly crosses in front of you.●When either your vehicle or the vehicle ahead of you accelerates rapidly.●The vehicle ahead of you is a motorcycle, a small vehicle, or a unique vehicle such as a tractor.●When you drive off-road or on a mountain road, or curved and winding road for an extended period that makes it difficult for the sensor/camera to
properly detect a vehicle in front of you.●When there are pedestrians or animals in front of your vehicle.●When you drive in bad weather (rain, fog, etc.).●A heavy load in the rear or modifications to the suspension tilts your vehicle.●An abnormal tire condition is detected (wrong tire size, flat tire, etc.).●When the windshield is blocked by dirt, mud, leaves, wet snow, etc.●When the temperature inside the system is high.●A sudden change between light and dark such as an entrance or exit of a tunnel.●You drive into the sunlight (e.g. at dawn or dusk).●When the windshield is dirty or cloudy.●When streetlights are perceived as the taillight of a vehicle in front of yours.●When driving at night, the vehicle ahead of you is running with either taillight bulb burned out.●When you drive in the shadows of trees, buildings, etc.●When your vehicle is towing a trailer.

uuWhen DrivinguLane Departure Warning (LDW)
200Driving
The system begins to search for lane markings when all the following conditions are met:
•The vehicle is traveling between at 40-90 mph (64-145 km/h).
•The vehicle is on a straight or slightly curved road.
•The turn signals are off.
•The brake pedal is not pressed.
The camera is located behind the rearview
mirror.
Press the LDW button to turn the system on
and off.
uThe indicator in the button comes on
when the system is on.■How the System Activates■LDW Camera
1How the System Activates
LDW may automatically shut off and the LDW
indicator comes and stays on.
2Indicators P. 661LDW Camera
Never apply a film or attach any objects to the
windshield that could obstruct the LDW camera's
field of vision.
Scratches, nicks, and other damage to the windshield
within the LDW 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 LDW
camera is necessary for the system to operate properly.
To help reduce the likelihood that high interior
temperatures will cause the camera system to shut off,
when parking, find a shady area or face the front of the
vehicle away from the sun. Also, do not use a reflective
sun shade that can concentrate heat on the camera.
If the FCW & LDW CAN NOT OPERATE message
appears:•Use the climate control system to cool down the
interior and, if necessary, the defroster mode when
windows are fogged.•Start driving the vehicle to lower the windshield
temperature, which cools down the area around
the LDW system.

uuWhen DrivinguLane Departure Warning (LDW)
Driving
LDW may not activate or may not recognize lanes, and may activate even when
keeping in the middle of a lane under the following conditions.■LDW Limitations
Condition
●When you drive in bad weather (rain, fog, etc.).●A heavy load in the rear or modifications to the suspension tilts your vehicle.●An abnormal tire condition is detected (wrong tire size, flat tire, etc.).●When the windshield is blocked by dirt, mud, leaves, wet snow, etc.●When the temperature inside the system is high.●A sudden change between light and dark such as an entrance or exit of a tunnel.●You drive into the sunlight (e.g. at dawn or dusk).●When the windshield is dirty or cloudy.●When you drive in the shadows of trees, buildings, etc.●When your vehicle is towing a trailer.●When you drive on a wet road surface following another vehicle.uThe camera may perceive the tire tracks in the water as lane lines.
●When there is snow or wheel tracks on the side of the road.●When the road has many repaired area or an erased lane line.●When the vehicle is running over painted signs or crosswalk markings.●When you drive in a lane with specific lane markups (e.g., bots-dots).

uuWhen DrivinguTPMS (Tire Pressure Monitoring System)
Driving
TPMS (Tire Pressure Monitoring System)Monitors the tire pressure while you are driving. If your vehicle’s tire pressure
becomes significantly low, the low tire pressure/TPMS indicator comes on and a
message appears on the multi-information display.
To select the tire pressure monitor, set the
power mode to ON and press the
button until you see the tire pressure screen.
If all the tire pressures are normal, TIRE
PRESSURE OK and the pressure of all four
tires will be displayed.
The pressure for each tire is displayed in PSI
(U.S.) or kPa (Canada).■Tire Pressure Monitor
1TPMS (Tire Pressure Monitoring System)
Conditions such as low ambient temperature and
altitude change directly affect tire pressure and can
trigger the low tire pressure/ TPMS indicator to come
on.
2If the Low Tire Pressure/TPMS Indicator
Comes On or Blinks P. 294
Tire pressure checked and inflated in:•Warm weather can become under-inflated in
colder weather.•Cold weather can become over-inflated in warmer
weather.
The low tire pressure/TPMS indicator will not come
on as a result of over inflation.
1Tire Pressure Monitor
The pressure displayed on the multi-information
display can be slightly different from the actual
pressure as measured by a gauge. If there is a
significant difference between the two values, or if
the low tire pressure/TPMS indicator and the message
on the multi-information display do not go off after
you have inflated the tire to the specified pressure,
have the system checked by a dealer.
TPMS ERROR may appear if you drive with the
compact spare tire, or there is a problem with the
TPMS.

uuBrakinguBrake 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.2Brake Assist System P. 215
2ABS (Anti-lock Brake System) P. 214■Foot Brake
1Foot 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, the brake pads need to be
replaced. Have the vehicle checked by a dealer.
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.

214
uuBrakinguABS (Anti-lock Brake System)
Driving
ABS (Anti-lock Brake System)Helps prevent the wheels from locking up, and helps you retain steering control by
pumping the brakes rapidly, much faster than you.
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. 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.
When the vehicle speed goes under 6 mph (10 km/h), the ABS stops.■ABS
1ABS (Anti-lock Brake System)NOTICEThe ABS may not function correctly if you use an
incorrect tire type and size.
When the ABS indicator comes on while driving,
there may be a problem with the system.
While normal braking is not affected, there is a
possibility of the ABS not operating. Have the vehicle
checked by a dealer immediately.
The ABS does not reduce the time or distance it takes
to stop the vehicle. It only helps with steering control
during hard braking.
In the following cases, your vehicle may need more
stopping distance than a vehicle without the ABS:•When driving on rough road surfaces, including
when driving on uneven surfaces, such as gravel or
snow.•When tire chains are installed.
You may hear a motor sound coming from the
engine compartment while system checks are being
performed immediately after starting the engine or
while driving. This is normal.

215
uuBrakinguBrake Assist System
Driving
Brake Assist SystemDesigned to assist the driver by generating greater braking force when you depress
the brake pedal hard during emergency braking.■Brake assist system operation
Press the brake pedal firmly for more powerful braking.
When brake assist operates, the pedal may wiggle slightly and an operating noise
may be heard. This is normal. Keep holding the brake pedal firmly down.
