comes on for 15 seconds when you pull
up the electric parking brake switch.

1Starting the Engine
Keep your foot firmly on the brake pedal when
starting the engine.
The engine is harder to start in cold weather and in
thinner air found at altitudes above 8,000 feet (2,400
meters).
When starting the engine in cold weather, turn off all
electrical accessories such as the lights, climate
control system, and rear defogger in order to reduce
battery drain.
If you live in a region where winter is extremely cold,
an engine block heater will improve starting and
warming of the engine. If temperatures consistently
below -22°F (-30°C) are expected, the coolant
mixture should be changed to a higher concentration
to prevent freezing. Consult a dealer for details.
If exhaust system sounds abnormal or you can smell
exhaust gas inside the vehicle, have your vehicle
checked by a dealer. There may be a problem with
the engine or exhaust system.
The immobilizer system protects your vehicle from
theft.
If an improperly coded device is used, the engine’s
fuel system is disabled.

Depress the brake pedal firmly and, when necessary,
apply the parking brake.
When shifting gears in extremely low temperatures
(-22°F/-30°C), there may be a short delay before the
shift is indicated in the display. Always confirm you
are in the correct gear before driving.

Shift Lever Operation
1Shift Lever OperationNOTICEWhen you change the shift lever from
(D to
(R and
vice versa, come to a complete stop and keep the
brake pedal depressed.
Operating the shift lever before the vehicle has come
to a complete standstill can damage the transmission.
Use the shift lever position indicator to check the
lever position before pulling away.
If the transmission indicator blinks when driving, in
any shift position, there is a problem with the
transmission.
Avoid sudden acceleration and have the transmission
checked by a dealer as soon as possible.
The fuel supply may be cut off if you drive at engine
speeds in or over the tachometer’s red zone (engine
speed limit). If this happens, you may experience a
slight jolt.
When the engine speed is increased while the shift
lever is in
( N, (P or
(R, the fuel supply may be cut
off even without the engine speed entering the
tachometer’s red zone.
It may not be possible to operate the shift lever if the
brake pedal is applied while the shift lever release
button is held down.
Depress the brake pedal first.

■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.
■
Sequential Shift Mode Operation
1 Sequential Shift Mode Operation
Each paddle shift operation makes a single gear
change.
To change gears continuously, release the paddle
shifter before pulling it again for the next gear.
Recommended Shift Points
Use this table as a guideline for efficient fuel
economy and effective emission control.
If the gear posit ion indicator blinks when you try to
shift up or down, this means your vehicle speed is not
in its allowable gear range.
Slightly accelerate to shift up and decelerate to shift
down while the indicator is blinking.
In sport mode, to prioritize the engine performance
enhancement, the transmission may not allow for
shifting up while the engine speed is low. Shift Up Normal Acceleration

uuWhen Driving uForward 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 streetlight s 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.

uuWhen Driving uLane Departure Warning (LDW)
Continued
Driving
Lane Departure Warning (LDW)Alerts you when the system detects a possibility of your vehicle unintentionally
crossing over detected 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 multi-information
display, letting you know that you need to
take appropriate action.
The system begins to search for la ne markings when all the following conditions are met:
• The vehicle is traveling between 40-90 mph (64-145 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.

The system can be used when the following conditions are met.
• The lane you are driving has detectable lane markers on both sides, and your
vehicle is in the center of the lane.
• The vehicle speed is between 45 – 90 mph (72 – 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

When the System can be Used
1Lane Keeping Assist System (LKAS)
*
•Shadows of adjacent object s are parallel to lane
markings.•The windshield is dirty.•Where the roadway has crossing or other lines
(e.g., such as at an intersection).
1 LKAS 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 withi n 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.
1 When 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.
