■Second gear lock mode
If you pull the
(+ paddle shifter while stopped or driving at 6 mph (10 km/h) or less,
the gear position will be locked in 2nd gear. This makes it easier to pull away on
slippery surfaces such as snow covered roads.
To cancel the 2nd gear lock mode, pull the
(- paddle shifter, or move the shift lever
from

uuWhen DrivinguForward Collision Warning (FCW)
*
Driving
FCW may not activate or may not detect a vehicle in front of your vehicle, and may
activate even when you are aware of a vehicle ahead of you, or when there is no
vehicle ahead, under the following conditions.■FCW Limitations
Condition
●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.●A vehicle suddenly crosses in front of you.●When either your vehicle or the vehicle ahead of you accelerates rapidly.●The vehicle ahead of you is a motorcycle, a small vehicle, or a unique vehicle such as a tractor.●When you drive off-road or on a mountain road, or curved and winding road for an extended period that makes it difficult for the sensor/camera to
properly detect a vehicle in front of you.●When there are pedestrians or animals in front of your vehicle.●When you drive in bad weather (rain, fog, etc.).●A heavy load in the rear or modifications to the suspension tilts your vehicle.●An abnormal tire condition is detected (wrong tire size, flat tire, etc.).●When the windshield is blocked by dirt, mud, leaves, wet snow, etc.●When the temperature inside the system is high.●A sudden change between light and dark such as an entrance or exit of a tunnel.●You drive into the sunlight (e.g. at dawn or dusk).●When the windshield is dirty or cloudy.●When streetlights are perceived as the taillight of a vehicle in front of yours.●When driving at night, the vehicle ahead of you is running with either taillight bulb burned out.●When you drive in the shadows of trees, buildings, etc.●When your vehicle is towing a trailer.

uuWhen DrivinguLane Departure Warning (LDW)

Driving
Lane Departure Warning (LDW)
*
Alerts you when the system detects a possibility of your vehicle unintentionally
crossing over left or right side lane markings.
If your vehicle is getting too close to detected
left or right side lane markings without a turn
signal activated, LDW will give audible and
visual alerts.
The beeper sounds and the Lane Departure
message appears on the MID, letting you
know that you need to take appropriate
action.
The system begins to search for lane markings when all the following conditions are
met:
•The vehicle is traveling between 40 and 90 mph (64 and 145 km/h).
•The vehicle is on a straight or slightly curved road.
•The turn signals are off.
•The brake pedal is not depressed.■How the System Works
1Lane Departure Warning (LDW)
*
Important Safety Reminder
Like all assistance systems, LDW has limitations.
Over-reliance on LDW may result in a collision. It is
always your responsibility to keep the vehicle within
your driving lane.
LDW only alerts you when lane drift is detected
without a turn signal in use. LDW may not detect all
lane markings or lane 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.
■How the System Activates
1How the System Activates
LDW may automatically shut off and the LDW
indicator comes and stays on.

Driving
LDW may not activate or may not recognize lanes, and may activate even when
keeping in the middle of a lane, under the following conditions.■LDW Limitations
Condition
●When you drive in bad weather (rain, fog, etc.).●A heavy load in the rear or modifications to the suspension tilts your vehicle.●An abnormal tire condition is detected (wrong tire size, flat tire, etc.).●When the windshield is blocked by dirt, mud, leaves, wet snow, etc.●When the temperature inside the system is high.●A sudden change between light and dark such as an entrance or exit of a tunnel.●You drive into the sunlight (e.g. at dawn or dusk).●When the windshield is dirty or cloudy.●When you drive in the shadows of trees, buildings, etc.●When your vehicle is towing a trailer.●When you drive on a wet road surface following another vehicle.uThe camera may perceive the tire tracks in the water as lane lines.
●When there is snow or wheel tracks on the side of the road.●When the road has many repaired area or an erased lane line.●When the vehicle is running over painted signs or crosswalk markings.●When you drive in a lane with worn-out lane markings.

uuWhen DrivinguLane Keeping Assist System (LKAS)
*
354Driving
The system can be used when the following conditions are met.
•The lane you are driving in has detectable lane markers on both sides, and your
vehicle is in the center of the lane.
•The vehicle speed is between 45 and 90 mph (72 and 145 km/h).
•You are driving on a straight or slightly curved road.
•The turn signals are off.
•The brake pedal is not depressed.
•The wipers are not in continuous operation.■How to activate the system
1.Press the MAIN button.
uThe LKAS is on in the MID.
The system is ready to use.
2.Press the LKAS button.
uLane outlines appear on the multi-
information display.
The system is activated.■When the System can be Used
1Lane Keeping Assist System (LKAS)
*
•Shadows of adjacent objects are parallel to lane
markings.•The windshield is dirty.•Where the roadway has crossing or other lines
(e.g., such as at an intersection).
1LKAS camera
Never apply a film or attach any objects to the
windshield that could obstruct the LKAS camera’s
field of vision.
Scratches, nicks, and other damage to the windshield
within the LKAS camera’s field of vision can cause the
system to operate abnormally. If this occurs, we
recommend that you replace the windshield with a
genuine Acura replacement windshield. Making even
minor repairs within the camera’s field of vision or
installing an aftermarket replacement windshield
may also cause the system to operate abnormally.
After replacing the windshield, have a dealer
recalibrate the camera. Proper calibration of the LKAS
camera is necessary for the system to operate properly.
If the Can Not Operate: Camera Too Hot message
appears:•Use the climate control system to cool down the
interior and, if necessary, the defroster mode when
windows are fogged.•Start driving the vehicle to lower the windshield
temperature, which cools down the area around
the LKAS camera.
1When the System can be Used
If the vehicle drifts toward either left or right lane line
due to the system applying torque, turn off the LKAS
and have your vehicle checked by a dealer.

uuWhen DrivinguAgile Handling Assist System
Driving
Agile Handling Assist SystemLightly brakes each of the front and rear wheels, as needed, when you turn the
steering wheel, and helps support the vehicle’s stability and performance during
cornering.
1Agile Handling Assist System
The agile handling assist system cannot enhance
stability in all driving situations. You still need to drive
and corner at speeds appropriate for the conditions
and always leave a sufficient margin of safety.
When the VSA® indicator comes on and stays on
while driving, the agile handling assist system does
not activate.
You may hear a sound coming from the engine
compartment while the system is activated. This is
normal.

uuWhen DrivinguTire Pressure Monitoring System (TPMS)
364Driving
To select the tire pressure monitor, set the power
mode to ON, and roll the multi-function
steering-wheel controls 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 Monitor
1Tire Pressure Monitor
The pressure displayed on the MID can be slightly
different from the actual pressure as measured by a
gauge. If there is a significant difference between the
two values, or if the low tire pressure/TPMS indicator
and the message on the MID 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.
