uuWhen Driving uTire Pressure Monitoring System (TPMS)
Driving
To select the tire pressure monitor, set the
power mode to ON, and press the
(information) button until you see the tire
pressure screen.
The pressure for each tire is displayed in psi
(U.S.) or kPa (Canada).
Tire Pressures Low is displayed when a tire
has significantly low pressure. The specific tire
is displayed on the screen.
■Tire Pressure Monitor1 Tire Pressure Monitor
The pressure displayed on the multi-information
display can be slightly different from the actual
pressure as measured by a gauge. If there is a
significant di fference between the two values, or if
the low tire pressure/TPMS indicator and the message
on the multi-information di splay do not go off after
you have inflated the tire to the specified pressure,
have the system checked by a dealer.
Tire Pressure Monitor Problem may appear if you
drive with the compact spare tire
*, or there is a
problem with the TPMS.

The system has three alert stages for a possible collision. However, depending on circumstances, the CMBSTM may not go through all of
the stages before initiating the last stage.

uuAcuraWatchTMuAdaptive Cruise Control (ACC)
Driving
Adaptive Cruise Control (ACC)
Helps maintain a constant vehicle speed a nd a set following-interval behind a vehicle
detected ahead of yours, without you havi ng to keep your foot on the brake or the
accelerator.
When ACC slows your vehicle by applying the brakes, your vehicle’s brake lights will
illuminate.1 Adaptive Cruise Control (ACC)
Important Reminder
As with any system, there are limits to ACC. Use the
brake pedal whenever necessary, and always keep a
safe interval betw een your vehicle and other vehicles.
For directions on the prop er handling of the radar
sensor, refer to the following page. 2 Radar Sensor P. 498
3WARNING
Improper use of ACC can lead to a crash.
Use ACC only when driving on expressways
or freeways and in go od road and weather
conditions.
3WARNING
ACC has limited braking capability.
When your vehicle speed drops below 22
mph (35 km/h), ACC will automatically
cancel and no longer will apply your
vehicle’s brakes.
Always be prepared to apply the brake
pedal when conditions require.
When to use
■Vehicle speed for adaptive cruise control: Desired speed in a range above
roughly 25 mph (40 km/h)
■Shift positions for ACC: In ( D or (S. The radar sensor is
behind the emblem.
The camera is
located behind the
rearview mirror.

Driving
■There is no vehicle ahead
Your vehicle maintains the set speed without
having to keep your foot on the brake or
accelerator pedal.
If there previously was a vehicle detected
ahead that kept your vehicle from traveling at
the set speed, ACC accelerates your vehicle to
the set speed, and then maintains it.
■When you depress the accelerator pedal
You can temporarily increase th e vehicle speed. In this case, there is no audible or
visual alerts even if a ve hicle is in the ACC range.
ACC stays on unless you cancel it. Once you release the accelerator pedal, the
system resumes the set speed.
There are times when the vehicle speed will decrease when the accelerator pedal is
lightly applied.
1 When in Operation
Even if the interval betw een your vehicle and the
vehicle detected ahead is short, ACC may start
accelerating your vehi cle under the following
circumstances:
•The vehicle ahead of you is going at almost the
same speed as, or faster than, your vehicle.
•A vehicle that cuts in front of you is going faster
than your vehicle, gradua lly increasing the interval
between the vehicles.
You can also set the system to beep when a vehicle in
front of you comes in and goes out of the ACC
detecting range. Change the ACC Forward Vehicle
Detect Beep setting.
2 Customized Features P. 99, 316
Limitations
You may need to use the brake to maintain a safe
interval when using ACC. Additionally, ACC may not
work properly under certain conditions.
