uuHonda Sensing ®u Lane Keeping Assist System (LKAS)
Continued
Driving
■The system operation is suspended if
you:
• Set the wipers to HI.
u Turning the wipers o ff or setting it to LO
or MIST resumes the LKAS.
• Decrease the vehicle speed to about 40
mph (64 km/h) or less.
u Increasing the vehicle speed to about 45
mph (72 km/h) or more resumes the
LKAS.
• Depress the brake pedal.
u The LKAS resumes and starts detecting
the lane lines again once you release the
brake pedal.
• Set the wiper switch to AUTO and the
wipers operate continuously.
u The LKAS resumes when the wipers stop
or operate intermittently.
When the LKAS is suspended,
the lane lines on the multi-
information disp lay change to
contour lines, and the beeper
sounds (if activated).

uuHonda Sensing ®u Road Departure Mitigation (RDM) System
Driving
The system becomes ready to start sear ching for lane markings when all the
following conditions are met:
• The vehicle is traveling between about 45 and 90 mph (72 and 145 km/h).
• The vehicle is on a straight or slightly curved road.
• The turn signals are off.
• The brake pedal is not depressed.
• The wipers are not in continuous operation.
• The vehicle is not accelera ting or braking, and the steering wheel is not being
turned.
• The system makes a determination that th e driver is not actively accelerating,
braking or steering.
■How the System Activates1 How the System Activates
The RDM system may automa tically shut off and the
indicator comes and stays on.
2 Indicators P. 74
RDM system function can be impacted when the
vehicle is:
•Not driven within a traffic lane.
•Driven on the inside edge of a curve, or outside of
a lane.
•Driven in a narrow lane.

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 Brake1Parking Brake
NOTICE
Release the parking brake fu lly before driving. The
rear brakes and axle can be damaged if you drive
with the parki ng brake applied.
If you start driving without fully releasing the parking
brake, a buzzer sounds as a warning, and Release
Parking Brake appears on the multi-information
display.
Always apply the parking brake when parking.

uuBraking uBrake 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 pe dal. 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.

2 Anti-lock Brake System (ABS) P. 464
■Foot Brake1Foot 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 me tallic 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 deal er. 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 vibr ation 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 pe dal 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 conf use drivers behind you.

uuBraking uAnti-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.
The electronic brake distribution (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distri bution 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 pe dal. 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 dow n. 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 yo u 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 unde r 6 mph (10 km/h), the ABS stops.
■ABS1Anti-lock Brake System (ABS)
NOTICE
The ABS may not function correct ly if you use a tire of
the wrong 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 wi ll 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, yo ur 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 snow 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.

uuBraking uBrake Assist System
Driving
Brake Assist System
Designed to assist the driver by generati ng 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.

Maintenance
Before Performing Maintenance
Inspection and Maintenance
For your safety, perform all listed inspections and maintenance to keep your vehicle
in good condition. If you become aware of an y abnormality (noise, smell, insufficient
brake fluid, oil residue on the ground, etc.), have your vehicle inspected by a dealer.
(Note, however, that service at a dealer is not mandatory to keep your warranties in
effect.)
■Daily inspections
Perform inspections before long distance trips, when washing the vehicle, or when
refueling.
■Periodic inspections
• Check the brake fluid level monthly.
2 Checking the Brake Fluid P. 500
•Check the tire pressure monthly. Examin e the tread for wear and foreign objects.
2Checking and Maintaining Tires P. 509
•Check the operation of the exterior lights monthly.
2Replacing Light Bulbs P. 501
•Check the condition of the wiper bl ades at least every six months.
2Checking and Maintaining Wiper Blades P. 507
■Types of Inspection and Maintenance
1Inspection and Maintenance
Maintenance, replacement, or repair of
emissions control devices and systems may be
done by any automotive repair establishment or
individuals using parts that are “certified” to
EPA standards.
According to state and fede ral regulations, failure to
perform maintenance on the maintenance main
items marked with # will not void your emissions
warranties. However, all ma intenance services should
be performed in accordan ce with the intervals
indicated by the mult i-information display.
2 Maintenance Service Items P. 487
If you want to perform complex maintenance tasks
that require more skills a nd tools, you can purchase a
subscription to the Service Express website at
www.techinfo.honda.com .
2 Authorized Manuals P. 577
If you want to perform ma intenance yourself, make
sure that you have the necessary tools and skills first.
After performing maintenanc e, update the records in
the separate maintenance booklet.
