Continued
Driving
The system may not properly detect lane ma rkings and the position of your vehicle
under certain conditions. Some examples of these conditions are listed below.
■Environmental conditions
• Driving in bad weather (rain, fog, snow, etc.).
• Sudden changes between light and dark, such as an entrance or exit of a tunnel.
• There is little contrast between lane lines and the roadway surface.
• Driving into low sunlight (e.g., at dawn or dusk).
• Strong light is reflec ted onto the roadway.
• Driving in the shadows of trees, buildings, etc.
• Shadows of adjacent objects are parallel to lane markings.
• Roadway objects or structures are misinterpreted as lane markers.
• Reflections on the interi or of the windshield.
• Driving at night or in a dark condition such as a tunnel.

■Roadway conditions
• Driving on a snowy or wet roadway (obscured lane marking, vehicle tracks,
reflected lights, road spray, high contrast).
• Driving on a road with temporary lane markings.
• Faint, multiple, or varied lane markings are visible on the roadway due to road
repairs or old lane markings.
• The roadway has merging, split, or crossing lines (e.g., such as at an intersection
or crosswalk).
• The lane markings are extremely narrow, wide, or changing.
• The vehicle in front of you is driving near the lane lines.
• The road is hilly or the vehicle is approaching the crest of a hill.
• Driving on rough or unpaved roads, or over bumpy surfaces.
• When objects on the road (c urb, guard rail, pylons, etc.) are recognized as white
lines (or yellow lines).
• Driving on roads with double lines.
■Vehicle conditions
• Headlight lenses are dirty or the headlights are not properly adjusted.
• The outside of the windshield is streake d or blocked by dirt, mud, leaves, wet
snow, etc.
• The inside of the windshield is fogged.
• The camera temperature gets too high.
• An abnormal tire or wheel condition (wrong sized, varied size or construction,
improperly inflated, comp act spare tire, etc.).
• The vehicle is tilted due to a heav y load or suspension modifications.

Driving
Front Sensor Camera
The camera, used in systems such as LKAS, RDM, ACC*, ACC with Low Speed
Follow*, and CMBSTM, 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

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
1Front Sensor Camera
Never apply a film or attach any objects to the
windshield, the hood, or th e front grille that could
obstruct the camera’s fiel d of vision and cause the
system to operate abnormally.
Scratches, nicks, and othe r damage to the windshield
within the camera’s fiel d of vision can cause the
system to operate abnormall y. If this occurs, we
recommend that you replac e the windshield with a
genuine Honda replacem ent windshield. Making
even minor repairs within th e camera’s field of vision
or installing an aftermarket replacement windshield
may also cause the system to operate abnormally.
After replacing the winds hield, have a dealer
recalibrate the camera. Pr oper 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.

Avoid strong impacts to the radar sensor cover.
For the CMBS to work properly:
•Always keep the radar sensor cover clean.•Never use chemical solvents or polishing powder
for cleaning the sensor cove r. Clean it with water
or a mild detergent.
•Do not put a sticker on th e radar sensor cover or
replace the radar sensor cover.
If you need the radar sensor to be repaired, or
removed, or the radar se nsor cover is strongly
impacted, turn off the syst em by using the CMBS OFF
button and take your vehicle to a dealer.

If the vehicle is involved in any of the following
situations, the radar sensor may not work properly.
Have your vehicle checked by a dealer:
•Your vehicle is involved in a frontal collision.•Your vehicle drives th rough deep water or is
submerged in deep water.
•Your vehicle strongly strikes a bump, curb, chock,
or embankment that coul d jar the radar sensor.

Use the parking brake to keep the vehicle stationary when parked. When the
parking brake is applied, you can manually or automatically release it.
■To apply
The electric parking brake can be applied any
time the vehicle has battery, no matter which
position the ignition switch
*1 is in.
Pull the electric parkin g brake switch up gently
and securely. u The indicator in th e switch comes on.
u The parking brake and brake system
indicator (red) comes on.
■To release
The ignition switch must be ON

to release the electric parking brake.
1. Depress the brake pedal.
2. Press the electric parking brake switch.

Manually releasing the parking brake using
the switch helps your ve hicle start slowly and
smoothly when facing down hill on steep hills.

ignition switch.
■Parking Brake1 Parking Brake
You may hear the electric parking brake system
motor operating from the re ar wheel area when you
apply or release the parki ng brake. This is normal.
The brake pedal may slightly move due to the electric
parking brake system opera tion when you apply or
release the parking br ake. This is normal.
You cannot apply or release the parking brake if the
12-volt battery goes dead. 2 Jump Starting P. 626
If you pull up and hold the electric parking brake
switch while driving, the brakes on all four wheels
are applied by the VSA
® system until the vehicle
comes to a stop. The electric parking brake then
applies, and the switch should be released
.
In the following situations, the parking brake
automatically operates.
•When your vehicle is stopped with the automatic
brake hold system activated for more than 10
minutes.
•When the driver’s seat belt is unfastened while
your vehicle is stopped and the brake hold system
is applied.
•When the engine is turned off while the brake hold
system is applied.
•When there is a problem with the brake hold
system while brake hold is applied.

Your vehicle is equipped with disc brakes at all four wheels. A vacuum power assist
helps to 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 an ti-lock brake system (ABS) helps you retain steering
control when braking very hard.

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 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 vibration of the brake pads against
the rotating brake disc.
Constantly using the brak e 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/speed position. With manual transmission
use a lower gear for gr eater engine braking.
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.
