Driving
Precautions While DrivingAvoid driving in deep water and on flooded roads. This can damage the engine,
driveline, or cause electrical component failure.■
In Rain
1Precautions While DrivingNOTICEDo not operate the shift lever while pressing the
accelerator pedal. You could damage the
transmission.NOTICEThe following can damage the under spoiler:•Parking the vehicle by a parking block•Parallel parking along the road shoulder•Driving toward the bottom of a hill•Driving up or down to a different surface level
(such as a road shoulder)•Driving on a rutted or bumpy road•Driving on a road with potholes.NOTICEIf you repeatedly turn the steering wheel at an
extremely low speed, or hold the steering wheel on
the full left or right position for a while, the electric
power steering (EPS) system heats up. The system
goes into a protective mode, and limits its
performance. The steering wheel becomes harder
and harder to operate. Once the system cools down,
the EPS system is restored.
Repeated operation under these conditions can
eventually damage the system.
If the power mode is set to ACCESSORY or VEHICLE
OFF (LOCK) while driving, the engine will shut down
and all steering and brake power assist functions will
stop, making it difficult to control the vehicle.

uuWhen Driving uLane Keeping Assist System (LKAS)
*
372Driving
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
1.Press the MAIN button.
u The LKAS is on in the multi-information
display.
The system is ready to use.
2. Press the LKAS button.
u Lane 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 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.

Maintenance
Safety When Performing MaintenanceSome of the most important safety precautions are given here.
However, we cannot warn you of every conc eivable hazard that can arise in
performing maintenance. Only you can decide whether or not you should perform
a given task.
• To reduce the possibility of fire or explosion, keep cigarettes, sparks, and flames
away from the battery and all fuel related parts.
• Never leave rags, towels, or other flammable objects under the hood.
u Heat from the engine and exhaust can ignite them causing a fire.
• To clean parts, use a commercially available degreaser or parts cleaner, not
gasoline.
• Wear eye protection and protective clothing when working with the battery or
compressed air.
• Engine exhaust contains carbon monoxide, which is poisonous and can kill you.
u Operate the engine only when there is sufficient ventilation.
• The vehicle must be in a stationary condition.
u Make sure your vehicle is parked on level ground, the parking brake is set, and
the engine is off.
• Be aware that hot parts can burn you.
u Make sure to let the engine and exhaust system cool thoroughly before
touching vehicle parts.
• Be aware that moving parts can injure you.
u Do not start the engine unless instructed, and keep your hands and limbs away
from moving parts.■

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
use the temporary tire repair kit so that you can drive to the nearest service station
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
(P
.
3. Turn on the hazard warning lights and set the power mode to VEHICLE OFF
(LOCK).

Getting Ready to Temporarily Repair the Flat Tire
1Temporarily Repairing a Flat Tire
The kit should not be used in the following situations.
Instead, contact a dealer or a roadside assistant to
have the vehicle towed.•The tire sealant has expired.•More than one tire is punctured.•The puncture or cut is larger than 3/16 inch (4mm).•The tire side wall is damaged or the puncture is
outside the contact area.•Damage has been caused by driving with the tire
extremely under inflated.•The tire bead is no longer seated.•The rim is damaged.
Do not remove a nail or screw that punctured the
tire. If you remove it from the tire, you may not be
able to repair the puncture using the kit.NOTICEDo not use a puncture-repairing agent other than the
one provided in the ki t that came with your vehicle. If
a different agent is us ed, you may permanently
damage the tire pressure sensor.

and air into the tire.
8. When the sealant injection is complete,
continue to add air.
9. After the air pressure reaches 32 psi (220
kPa), turn off the kit.
After the air pressure reaches front:35 psi
(240 kPa)/rear:33 psi (230 kPa), turn off
the kit.
u To check the pressure, occasionally turn
off the compressor and read the gauge.
10. Unplug the power plug from the accessory
power socket.
11. Unscrew the sealant/air hose from the tire
valve stem. Reinstall the valve cap.
12. Press the pressure relief button until the

1Injecting Sealant and Air
If the required air pressure is not reached within 15
minutes, the tire may be too severely damaged for
the kit to provide the necessary seal and your vehicle
will need to be towed.
