uuBraking uCollision Mitigation Braking SystemTM (CMBSTM)*
Driving
Collision Mitigati on Braking SystemTM (CMBSTM)*
Can assist you when there is a possibility of your vehicle colliding with a vehicle or a
pedestrian detected in front of yours. The CMBSTM is designed to alert you when a
potential collision is determined, as well as to reduce your vehicle speed to help
minimize collision severity when a collision is deemed unavoidable.
■How the system works
1 Collision Mitigation Braking SystemTM (CMBSTM)*
Important Safety Reminder
The CMBSTM is designed to reduce the severity of an
unavoidable collision. It does not prevent collision nor
stop the vehicle automatically. It is still your
responsibility to operate the brake pedal and steering
wheel appropriately acco rding to the driving
conditions.
The CMBS
TM may not activate or may not detect a
vehicle in front of y our vehicle under certain
conditions: 2 CMBS
TM Conditions and Limitations P. 498

1How the system works
Rapid vibrations on the st eering wheel alert you
when the your vehicle speed is between
19 and 62 mph (30 and 100 km/h) with an oncoming
vehicle detected in front of you.
When CMBS activates, it may automatically apply the
brakes. CMBS cancels when your vehicle stops, or a
potential collision is no longer determined.
The system starts monitoring the roadway ah ead when your vehicle speed is about
3 mph (5 km/h) and there is a vehicle in front of you. The radar sensor is
in the front grille.
The CMBS
TM activates when:●The speed difference between your vehicle and a vehicle or pedestrian
detected in front of you becomes about 3 mph (5 km/h) and over with a chance
of a collision.
●Your vehicle speed is about 62 mph (100 km/h) or less and there is a chance of a
collision with an oncoming detected vehicle or a pedestrian in front of you. The camera is
located behind the
rearview mirror.

■Detection limitations
• A vehicle or pedestrian suddenly crosses in front of you.
• The distance between your vehicle and the vehicle or pedestrian ahead of you is
too short.
• A vehicle cuts in front of you at a slow speed, and it brakes suddenly.
• When you accelerate rapidly and approach the vehicle or pedestrian ahead of you
at high speed.
• The vehicle ahead of you is a motorcycle, bicycle, mobility scooter or other small
vehicle.
• When there are animals in front of your vehicle.
• When you drive on a cu rved, winding or undulating road that makes it difficult for
the sensor to properly detect a vehicle in front of you.
• The speed difference between your vehicle an d a vehicle or pedestrian in front of
you is significantly large.
• An oncoming vehicle suddenly comes in front of you.
• Another vehicle suddenly comes in front of you at an intersection, etc.
• Your vehicle abruptly crosses over in front of an oncoming vehicle.
• When driving through a narrow iron bridge.
• When a pedestrian blends in with the background.
• When a pedestrian is bent over or squatting, or when their hands or raised or they
are running.
• When several pedestrians are walking ahead in a group.
• When the lead vehicle suddenly slows down.

Maintenance
Brake Fluid
The fluid level should be between the MIN
and MAX marks on the side of the reserve
tank.
Refilling Window Washer Fluid
Check the amount of window washer fluid.
If the level is low, fill the washer reservoir.
If the washer fluid is low, a message appears on the multi-information display.
Pour the washer fluid carefully. Do not overflow the reservoir.
Specified fluid: Honda Heavy Duty Brake Fluid DOT 3
■Checking the Brake Fluid
1Brake Fluid
NOTICE
Brake fluid marked DOT 5 is not compatible with your
vehicle’s braking system and can cause extensive
damage.
If the specified brake fluid is not available, you should
use only DOT 3 or DOT 4 fluid from a sealed
container as a temporary replacement.
Using any non-Honda brake fluid can cause corrosion
and decrease the longevity of the system. Have the
brake system flushed and re filled with Honda Heavy
Duty Brake Fluid DOT 3 as soon as possible.
If the brake fluid level is at or below the MIN mark,
have a dealer inspect the vehicle for leaks or worn
brake pads as soon as possible.

Handling the Unexpected
If a Tire Goes Flat
Changing a Flat Tire
If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then, stop in a safe plac e. Replace the flat tire with a compact
spare tire. Go to a dealer as soon as possib le to have the full-size tire repaired or
replaced.
1. Park the vehicle on firm, level, non-slip pery surface and apply the parking brake.
2. Move the shift lever to
(P.
3. Turn on the hazard warning lights an d set the power mode to VEHICLE OFF
(LOCK).
1 Changing a Flat Tire
Follow compact spare precautions:
Periodically check the tire pressure of the compact
spare. It should be set to the specified pressure.
Specified Pressure: 60 psi (420 kPa, 4.2 kgf/cm
2)
When driving with the compact spare tire, keep the
vehicle speed under 50 mph (80 km/h). Replace with
a full-size tire as soon as possible.
The compact spare tire and wheel in your vehicle are
specifically for this model. Do not use them with
another vehicle. Do not us e another type of compact
spare tire or wheel with your vehicle.
Do not mount tire chains on a compact spare tire.
If a chain-mounted front tire goes flat, remove one of
the full-size rear tires and replace it with the compact
spare tire. Remove the flat front tire and replace it
with the full-size tire that was removed from the rear.
Mount the tire chains on the front tire.
Do not use a puncture-repairi ng agent on a flat tire,
as it can damage the tire pressure sensor.
