■When a vehicle is traveling ahead
When a vehicle ahead of yours is detected entering the Traffic Jam Assist detection
area, Traffic Jam Assist adju sts the speed of your vehicle to maintain the selected
interval between your vehicle and the one ahead. It also applies steering torque to
keep your vehicle in the center of the detected lane.
■How Traffic Jam Assist Works1 How Traffic Jam Assist Works
If your vehicle veers too far to the right or the left of
the white (yellow) traffic lane lines while Traffic Jam
Assist is active, deactivate Traffic Jam Assist and have
an authorized Acura deal er inspect your vehicle.
In some cases the system cannot properly detect the
traffic lane lines and, as a result, will not provide
steering assistance. 2 Traffic Jam Assist: Conditions and
limitations P. 530
If the driver takes his or her hands off the steering
wheel or does not adequate ly maintain control of
steering, the warning below will appear.
If the driver does not grip the steering wheel after the
warning above has repeatedly appeared, a warning
buzzer will sound and Traffi c Jam Assist will be
canceled.

■When no vehicle is traveling ahead
If the vehicle detected ahead disappears from
the travel path of your vehicle (for example, it
changes lanes), Traffic Jam Assist will be
deactivated temporarily and your vehicle will
gradually accelerate until it reaches the set
speed, after which it will maintain that speed.1How Traffic Jam Assist Works
If the vehicle detected ahead suddenly slows down,
or if another vehicle is de tected cutting in front of
yours, a warning buzzer will sound, and a warning in
the driver information interface and head-up

To cancel Traffic Jam Assist, you can do any of the following:
• Press the button.
• Press the LKAS button.
• When the ACC with Low Speed Follow is deactivated.
■When Traffic Jam Assist may au tomatically be suspended when:
The system is temporarily canceled automa tically under the following circumstances.
• The system fails to detect lane lines.
• The vehicle ahead of yo u cannot be detected.
• The steering wheel is turned quickly.
• You fail to steer the vehicle.
• The vehicle in front of you is driving near the lane lines.
• The wipers are set to high.
• The interval between your vehicle and th e one traveling ahead is over 197 feet
(60m).
Once these conditions no longer exist, th e Traffic Jam Assist automatically resumes.
■Canceling Traffic Jam Assist1How Traffic Jam Assist Works
If you are traveling slower than the vehicle detected
ahead or a vehicle that is de tected cutting in front of
you and the interval betw een your vehicle and the
detected vehicle gradually increases, your vehicle will
continue to follow that vehicle without emitting any
warning, even if the interv al between the vehicle is
minimal.
1 When Traffic Jam Assist may automatically be suspended when:
You are traveling over 45mph (72km/h).
u When the speed of the vehicle reaches 45mph
(72km/h), Traffic Jam Assist is deactivated and LKAS
is activated instead. Once the speed of the vehicle
drops to under 42mph (68km/ h), Traffic Jam Assist
is reactivated.

Driving
Road Departure Mi tigation System
Alerts and helps to assist you when the system detects a possibility of your vehicle
unintentionally crossing over detected lane markings and/or leaving the roadway
altogether.
The front camera behind the rearview mirror
monitors left and right lane markings (in white
or yellow). If your vehicle is getting too close
to detected lane markings without a turn
signal activated, the system, in addition to a
visual alert, applies st eering torque and alerts
you with rapid vibrations on the steering
wheel, to help you remain within the detected
lane.
2 Customized Features P. 345
As a visual alert, appears on the gauge.
If the system determines that its steering input
is insufficient to keep your vehicle on the
roadway, it may apply braking.
u Braking is applied only when the lane
markings are solid continuous lines.
■How the System Works
1Road Departure Mitigation System
Important Safety Reminder
Like all assistance systems, the Road Departure
Mitigation system has limitations.
Over-reliance on the Road Departure Mitigation system
may result in a collision. It is always your responsibility to
keep the vehicle within your driving lane.
The Road Departure Mitigati on system only alerts you
when lane drift is detected without a turn signal in use.
The Road Departure Mitigation system may not detect
all lane markings or lane or roadway departures;
accuracy will vary based on weather, speed and lane
marker condition. It is always your responsibility to
safely operate the vehicle and avoid collisions.
You can read about handling information for the
camera equipped with this system.

uuBraking uBrake System
Driving
Your vehicle is equipped with disc brakes at all four wheels. 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 brak ing very hard.
2Brake Assist System P. 559
2 Anti-lock Brake System (ABS) P. 558
■Foot Brake1Foot 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 vibr ation of the brake pads against
the rotating brake disc.
Constantly using the brake 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.
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.

uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)
Helps prevent the wheels from locking up, an d helps you retain steering control by
pumping the brakes rapidly, much faster than you can.
The electronic brake distribution (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distri bution according to vehicle loading.
You should never pump the brake pedal. Let the ABS work for you by always
keeping firm, steady pressure on the brake pe dal. This is sometimes referred to as
“stomp and steer.”
■ABS operation
The brake pedal may pulsate slightly when the ABS is working. Depress the brake
pedal and keep holding the pedal firmly do wn. On dry pavement, you will need to
press on the brake pedal very hard before the ABS activates. However, you may feel
the ABS activate immediately if yo u are trying to stop on snow or ice.
ABS may activate when you depress the brake pedal when driving on:
• Wet or snow covered roads.
• Roads paved with stone.
• Roads with uneven surfaces, such as potholes, cracks, manholes, etc.
When the vehicle speed goes unde r 6 mph (10 km/h), the ABS stops.
■ABS1Anti-lock Brake System (ABS)
NOTICE
The ABS may not function correctly if you use a tire of
the wrong size or type.
If the ABS indicator comes on while driving, there
may be a problem with the system.
While normal braking will not be affected, there is a
possibility that the ABS wi ll not be operating. Have
your vehicle checked by a dealer immediately.
The ABS is not designed for the purpose of reducing
the time or distance it takes for a vehicle to stop: It is
designed to limit brake lo ckup which can lead to
skidding and loss of steering control.
In the following cases, yo ur vehicle may need more
distance to stop than a vehicle without the ABS:
•You are driving on rough or uneven road surfaces,
such as gravel or snow.
•The tires are equipped with tire chains.
The following may be observed with the ABS system:
•Motor sounds coming from the engine
compartment when the brakes are applied, or
when system checks are being performed after the
engine has been started and while the vehicle
accelerates.
•Brake pedal and/or the vehicle body vibration when
ABS activates.
These vibrations and sou nds are normal to ABS
systems and are no cause for concern.
