OCN7H030009
Front air bags are not designed to inflate
in rear collisions, because occupants
are moved backward by the force of the
impact. In this case, inflated air bags
would not provide any additional benefit.
OCN7H030010
Front air bags may not inflate in side
impact collisions, because occupants
move in the direction of the collision,
and thus in side impacts, front air bag
deployment would not provide additional
occupant protection.
However, side and curtain air bags may
inflate depending on the severity of
impact.
OCN7030053
In an angled collision, the force of impact
may direct the occupants in a direction
where the air bags would not be able to
provide any additional benefit, and thus
the sensors may not deploy any air bags.
OCN7H030011
Just before impact, drivers often brake
heavily. Such heavy braking lowers the
front portion of the vehicle causing it
to “ride” under a vehicle with a higher
ground clearance. Air bags may not
inflate in this “underride” situation
because deceleration forces that are
detected by sensors may be significantly
reduced by such “underride” collisions.

EXTERIOR LIGHTS
Lighting control
To operate the lights, turn the knob at
the end of the control lever to one of the
following positions:
ODN8A059200
1. OFF position
2. AUTO headlamp position
3. Parking lamp position
4. Headlamp position
Daytime running light (DRL)
The Daytime Running Lights (DRL) can
make it easier for others to see the front
of your vehicle during the day, especially
after dawn and before sunset.
The DRL system will turn the dedicated
lamp OFF when:
• The headlamps are ON.
• The parking lamps are ON.
• The vehicle is turned off.
• The parking brake is engaged.
OCN7050055
AUTO headlamp position
The parking lamp and headlamp will
be turned ON or OFF automatically
depending on the amount of daylight as
measured by the ambient light sensor on
the center dash (1).
Even with the AUTO headlamp feature
in operation, it is recommended to
manually turn ON the headlamps when
driving at night or in a fog, driving in the
rain, or when you enter dark areas, such
as tunnels and parking facilities.
NOTICE
• Do not cover or spill anything on
the sensor (1) located in front of the
instrument panel.
• Do not clean the sensor using
a window cleaner, the cleanser
may leave a light film which could
interfere with sensor operation.
• If your vehicle has window tint or
other types of metallic coating on
the front windshield, the AUTO
headlamp system may not work
properly.

• There is a group of pedestrians or a
large crowd in front
• The pedestrian is wearing clothing
that easily blends into the
background, making it difficult to
detect
• The pedestrian is difficult to
distinguish from the similar shaped
structure in the surroundings
• You are driving by a pedestrian,
traffic sign, structure, etc. near the
intersection
• Driving in a parking lot
• Driving through a tollgate,
construction area, unpaved road,
partial paved road, uneven road,
speed bumps, etc.
• Driving on an incline road, curved
road, etc.
• Driving through a roadside with trees
or streetlights
• The adverse road conditions cause
excessive vehicle vibrations while
driving
• Your vehicle height is low or high
due to heavy loads, abnormal tire
pressure, etc.
• Driving through a narrow road where
trees or grass or overgrown
• There is interference by
electromagnetic waves such as
driving in an area with strong radio
waves or electrical noise WARNING
• Driving on a curve

Forward Collision-Avoidance Assist
may not detect other vehicles
or pedestrians in front of you on
curved roads adversely affecting the
performance of the sensors. This may
result in no warning or braking assist
when necessary.
When driving on a curve, you must
maintain a safe braking distance,
and if necessary, steer the vehicle
and depress the brake pedal to
reduce your driving speed in order to
maintain a safe distance.

If this occurs, the system may
unnecessarily warn the driver and
control the brake. Always check the
traffic conditions around the vehicle.•

Forward Collision-Avoidance Assist
may not detect other vehicles or
pedestrians in front of you while
driving uphill or downhill adversely
affecting the performance of the
sensors.
This may result in unnecessary
warning or braking assist, or no
warning or braking assist when
necessary.
Also, vehicle speed may rapidly
decrease when a vehicle or
pedestrian ahead is suddenly
detected.
Always have your eyes on the road
while driving uphill or downhill and
if necessary, steer the vehicle and
depress the brake pedal to reduce
your driving speed in order to

• Changing lanes
OADAS032SD[A] : Your vehicle,
[B] : Lane changing vehicle
When a vehicle moves into your lane
from an adjacent lane, it cannot
be detected by the sensor until it
is in the sensor's detection range.
Forward Collision-Avoidance Assist
may not immediately detect the
vehicle when the vehicle changes
lanes abruptly. In this case, you must
maintain a safe braking distance,
and if necessary, steer the vehicle
and depress the brake pedal to
reduce your driving speed in order to
maintain a safe distance.
OADAS033SD[A] : Your vehicle,
[B] : Lane changing vehicle,
[C] : Same lane vehicle
When a vehicle in front of you
merges out of the lane, Forward
Collision-Avoidance Assist may not
immediately detect the vehicle that
is now in front of you.
In this case, you must maintain a safe
braking distance, and if necessary,
steer the vehicle and depress the
brake pedal to reduce your driving
speed in order to maintain a safe
distance.

When you are driving forward out of
a parking space, if the system detects
that there is a collision risk with an
approaching vehicle in the blind spot,
the function will help avoid a collision by
applying the brake.
