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.
ONX4030053
Front air bags may not inflate in
rollover accidents because front air bag
deployment would not provide additional
occupant protection.
ONX4030052
Air bags may not inflate if the vehicle
collides with objects such as utility poles
or trees, where the point of impact is
concentrated and the collision energy is
absorbed by the vehicle structure.

Information
After reconnecting the vehicle battery
power supply or charging the battery, it
may take time to operate due to remote
renewal of security information. In this
case, when you lock or unlock the doors
using your smartphone Digital Key, it
may take a little longer for the vehicle to
authenticate. Hold your smartphone near
the NFC door handle sensor for a few
seconds or until you hear the door locks
actuate.
Note that if your vehicle is parked in an
area where cell coverage is weak, the
smartphone Digital Key can still be used on
for a limited number of times to unlock and
start your vehicle.
After starting your vehicle, it is
recommended to leave your smartphone
on the wireless charging pad until cell
phone service is stronger and digital key
authentication can occur.
Once authentication is complete, the
wireless charger will turn on (wireless
charging LED will illuminate).
CAUTION
The engine can be turned on if the
registered smartphone or card key is
placed on the interior authentication
pad (wireless charger). Do not leave
children unattended in the vehicle
when using the smartphone Digital Key.
Serious injury or death can occur.
Do not leave anyone in the vehicle
without knowledge of the Digital Key
system when using the smartphone
Digital Key. Always have the registered
digital key (smartphone) or card key
with you to prevent vehicle theft when
leaving the vehicle.
For more information, refer to the
Engine Start/Stop button in chapter 6.

Daytime Running Light (DRL)
The Da

ytime 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
Daytime Running Lights (DRL) should
be illuminated whenever you are driving
during daylight hours. The DRL system
will be ON when the headlamp stalk is
in the OFF or the AUTO Position (when
daylight is detected) and the Electronic
Parking Brake (EPB) is released.
The DRL system will turn off when:
• The headlamps are ON.
• The parking brake is applied.
• The vehicle is turned off.
• Parking Brake is applied
ODN8A059201
AUTO headlamp position
The position lamp and headlamp will
be turned ON or OFF automatically
depending on the amount of daylight as
measured by the ambient light sensor (1)
at the upper end of the windshield glass.
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 at the upper end of
the windshield glass.
• 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,
cyclists or a large crowd in front
• The pedestrian or cyclist is wearing
clothing that easily blends into the
background, making it difficult to
detect
• The pedestrian or cyclist is difficult to
distinguish from the similar shaped
structure in the surroundings
• You are driving by a pedestrian,
cyclist, 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 are 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
OADAS003

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.

Forward Collision-Avoidance Assist
may detect a vehicle, pedestrian or

lane when driving on a curved road.
If this occurs, Forward Collision-
Avoidance Assist may unnecessarily
warn the driver and control the
brake. Always check the traffic
conditions around the vehicle.•
Driving on a slope
OADAS009

Forward Collision-Avoidance Assist
may not detect other vehicles,
pedestrians or cyclists 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, pedestrian
or cyclist 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
maintain a safe distance.

• Changing lanes
OADAS032[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.
OADAS033[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.

parking space, if Blind-Spot Collision-
Avoidance Assist judges that there is a
collision risk with an approaching vehicle
in the blind spot, it will help avoid a
collision by applying the brake.
