Can assist you when there is a possibility of your vehicle colliding with a vehicle
detected in front of yours. The CMBS
TM is designed to alert you when a potential
collision is determined, as well as to reduce your vehicle speed when a collision is
deemed unavoidable to help minimize collision severity.
■How the system works

TM (CMBS
TM)*
Important Safety Reminder
The CMBS
TM 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 according to the driving
conditions.
The CMBSTM may not activate or may not detect a
vehicle in front of your vehicle under the following
conditions:
•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.•When you accelerate rapidly and approach the
vehicle ahead of you at high speed.•The vehicle ahead of you is a motorcycle or other
small vehicle.•A vehicle suddenly crosses in front of you.•When you drive on a curved or winding road that
makes it difficult for the sensor to properly detect a
vehicle in front of you.•When there are pedestrians or animals in front of
your vehicle.
A radar sensor starts to monitor if there is a vehicle in front of you when your
vehicle speed is above 10 mph (15 km/h).
The radar sensor is
in the front grille.
The CMBS
TM activates when the speed difference between your vehicle and a
vehicle detected in front of you becomes more than 10 mph (15 km/h) with a
chance of a collision.

Accessories and ModificationsAccessoriesWhen installing accessories, check the following:
•Do not install accessories on the windshield. They can obstruct your view and
delay your reaction to driving conditions.
•Do not install any accessories over areas marked SRS Airbag, on the sides or backs
of the front seats, on front or side pillars, or near the side windows. Accessories
installed in these areas may interfere with proper operation of the vehicle’s
airbags or may be propelled into you or another occupant if the airbags deploy.
•Be sure electronic accessories do not overload electrical circuits or interfere with
proper operation of your vehicle.

•Before installing any electronic accessory, have the installer contact a dealer for
assistance. If possible, have a dealer inspect the final installation.ModificationsDo not modify your vehicle or use non-Acura components that can affect its

uuChecking and Maintaining TiresuTire and Wheel Replacement
Maintenance
Tire and Wheel ReplacementReplace your tires with radials of the same size, load range, speed rating, and
maximum cold tire pressure rating (as shown on the tire’s sidewall). Using tires of a
different size or construction can cause the ABS and vehicle stability assist (VSA®)
system to work incorrectly.
It is best to replace all four tires at the same time. If that isn’t possible, replace the
front or rear tires in pairs.
Make sure that the wheel’s specifications match those of the original wheels.
If you replace a wheel, only use TPMS specified wheels approved for your vehicle.

Handling the Unexpected
If a Tire Goes FlatTemporarily Repairing a Flat TireIf the tire has a large cut or is otherwise severely damaged, you will need to have the
vehicle towed. If the tire only has a small puncture, from a nail for instance, you can

for a more permanent repair.
If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then stop in a safe place.
1.Park the vehicle on a firm, level, and non-slippery surface and apply the parking
brake.
2.Move the shift lever to

to the steering and braking systems, it will require significantly more physical
effort and time to steer and slow the vehicle. Downshift gears and use both feet
on the brake pedal, if necessary, to slow the vehicle and stop immediately in a
safe place.
