uuTowing a Trailer uDriving Safely with a Trailer
Driving
Driving Safely with a Trailer
• Have the trailer properly serviced and keep it in good condition.
• Make sure that all the weights and load in the vehicle and trailer are within limits.
2Towing Load Limits P. 409
•Securely attach the hitch, safety chains, and other necessary parts to the trailer.
• Securely store all the items in and on the tr ailer so that they do not shift while
driving.
• Check if the lights and brakes on the trailer are working properly.
• Check the pressure of the traile r tires, including the spare.
• Turn off the Low Speed Braking Control syst em. It may activate if it detects the
vehicle being towed as an obstacle.
2 System On and Off P. 469
•Turn off the rear parking sensor system.
2 Turning off All Rear Sensors P. 526
•Drive slower than normal.
• Obey posted speed limits for vehicles with trailers.
• Use the
(D position when towing a trailer on level roads.
• Turn more slowly and with a wider turning arc than normal.
• Allow more time and distance for braking.
• Do not brake or turn suddenly.
■Things You Need To Know Before Towing a Trailer
■Towing Speeds and Gears
■Turning and Braking
2.0 L engine models
1Driving Safely with a Trailer
Operating speed when towing a trailer must not
exceed 62 mph (100 km/h).
Parking
In addition to the normal precautions, place wheel
chocks at each of the trailer’s tires.
Models with Low Speed Braking Control
1Towing Speeds and Gears
When towing a fixed-sided trailer (e.g., camper), do
not exceed 55 mph (88 km/h). At higher speeds, the
trailer may sway or af fect vehicle handling.

uuHonda Sensing ®u Low Speed Braking Control*
Continued
Driving
Low Speed Braking Control*
Using sonar sensors located on the front a nd rear bumpers, the vehicle detects if
there is danger of a potential collision with a wall or other obstacle. The system is
designed to alert you when a potential collision is determined, as well as assist in
reducing speed, avoiding collisions, and reducing collision severity.1 Low Speed Braking Control*
When trapped in a railway crossing, the system may
detect the crossing gate as an obstacle and activate.
If this happens, Low Spee d Braking Control will
automatically cancel after a certain amount of time
after stopping, so conti nue to move forward.
If the system is activated by curbs/parking curbs or
level differences on the road and you are unable to
park or clear them, turn the system off.
3WARNING
It is not possible for the Low Speed Braking
Control to avoid collisions or reduce
damage from collision s in all situations
where the accelerator has been depressed
accidentally or with too much force.
Overreliance on this system may result in a
collision and serious injury or death.
It is your responsibility to always check your
shift position, pedal location and
surroundings, and safely operate the
vehicle.

Sonar Sensors*
■Location and range of sensors
The sonar sensors are situated in the front and rear bumpers.1Sonar Sensors*
For the sonar sensors to work properly, do not:•Place stickers or other objects on or around the
sensors.
•Hit the area around the sensors.•Attempt to take apart any sensor.
•Put any accessories on or around the sensors.
Consult with a dealer if:
•A sensor has been subjected to shock.
•Work needs to be done to the area around a
sensor.
In the following cases, the sonar sensors may not
work properly. Have your ve hicle checked by a dealer.
•The front or rear bumper has made contact with a
hill, parking block, curb, embankment, etc.
•The vehicle has been involv ed in frontal or rear
collision.
•The vehicle has been driven through a deep
puddle.

Parking Sensor System*
The corner and center sensors monitor obstacles around your vehicle, and the
beeper, driver information interface and audio/informatio n screen let you know the
approximate distance between your vehicle and the obstacle.
■The sensor location and range
1 Parking Sensor System*
Even when the system is on, always confirm if there is
no obstacle near your ve hicle before parking.
The system may not work properly when:
•The sensors are covered with snow, ice, mud or
dirt.
•The vehicle is on uneven su rface, such as grass,
bumps, or a hill.
•The vehicle has been out in hot or cold weather.•The system is affected by devices that emit
ultrasonic waves.
•Driving in bad weather.
The system may not sense:
•Thin or low objects.•Sonic-absorptive materials, such as snow, cotton,
or sponge.
•Objects directly under the bumper.
Do not put any accessories on or around the sensors.Within about 24 in (60 cm) or less
