ONE1031069
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.
ONE1031070
Front air bags may not inflate in
rollover accidents because front air bag
deployment would not provide additional
occupant protection.
Information
With rollover sensor
The side and curtain air bags may inflate
in a rollover situation, when it is detected
by the rollover sensor.
Information
Without rollover sensor
The side and/or curtain air bags may
inflate when the vehicle is rolled over by a side impact collision, if the vehicle
is equipped with side and/or curtain air bags.
ONE1031071K
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.

System Malfunction
OOSEV040521L
Check smart recuperation system
The message will appear when the
system is not functioning normally. The
system will be cancelled and the word
'AUTO' on the cluster will disappear and
instead display regenerative braking
level. Check for foreign substances on
the front radar. Remove any dirt, snow, or
foreign material that could interfere with
the radar sensors. If the system still does
not operate normally, take your vehicle
to an authorized HYUNDAI dealer and
have the system checked.
Limitations of the System
The Smart Recuperation System may
not operate properly in certain situations
when the driving condition is beyond the
performance of the front radar sensor.
Driver's attention is required in such
cases when the system does not react
properly or operate unintentionally.On curves
OTM058117
When coasting on the curve, the system
may not detect the vehicle in your lane
and the regenerative braking level will
reduce automatically, making you feel
that the vehicle is accelerating.
Also, if the system suddenly recognizes
the vehicle in front, the regenerative
braking level will increase automatically,
making you feel that the vehicle is
decelerating.
The driver must maintain a safe braking
distance, and if necessary, depress the
brake pedal to reduce your driving speed
in order to maintain a safe distance.
OTM058073
Your vehicle speed can be reduced due
to a vehicle in the adjacent lane.
Apply the accelerator pedal and select
the appropriate speed. Check to be sure
that the road conditions permit safe
operation of the Smart Recuperation
System.

On inclines
ONE1071209
When coasting on an uphill or downhill,
the system may not detect the vehicle in
your lane and the regenerative braking
level will reduce automatically, making
you feel that the vehicle is accelerating.
Also, if the system suddenly recognizes
the vehicle in front, the regenerative
braking level will increase automatically,
making you feel that the vehicle is
decelerating.
The driver must maintain a safe braking
distance, and if necessary, depress the
brake pedal to reduce your driving speed
in order to maintain a safe distance. Lane changingOTM058074
• A vehicle which moves into your lane
from an adjacent lane cannot be
recognized by the sensor until it is in
the sensor's detection range.
• The radar may not detect immediately
when a vehicle cuts in suddenly.
Always pay attention to the traffic,
road and driving conditions.

Vehicle recognition
OTM058128
Some vehicles in your lane cannot be
recognized by the sensor: - Narrow vehicles such as motorcycles or bicycles
- Vehicles offset to one side
- Slow-moving vehicles or sudden- decelerating vehicles
- Stopped vehicles (When the vehicle ahead drives away, the system may not
detect a stopped vehicle.)
- Vehicles with small rear profile such as trailers with no loads
A vehicle ahead cannot be recognized
correctly by the sensor if any of following
occurs: - When the vehicle is pointing upwards due to overloading in the luggage
compartment.
- While the steering wheel is operating.
- When driving to one side of the lane.
- When driving on narrow lanes or on curves.
- Apply the brake or accelerator pedal if necessary.
WARNING
When using the Smart Recuperation
System take the following precautions: • If an emergency stop is necessary,
you must apply the brakes.
• Keep a safe distance according to
road conditions and vehicle speed. If
the vehicle to vehicle distance is too close during a high-speed driving, a
serious collision may result.
• Always maintain sufficient braking
distance and decelerate your vehicle
by applying the brakes if necessary.
• The Smart Recuperation System
cannot recognize a stopped vehicle,
pedestrians or an oncoming vehicle.
Always look ahead cautiously to
prevent unexpected and sudden
situations from occurring.
• Vehicles moving in front of you with
a frequent lane changes may cause
a delay in the system's reaction or
may cause the system to react to a
vehicle actually in an adjacent lane.
Always drive cautiously to prevent
unexpected and sudden situations
from occurring.
• The Smart Recuperation System
may not recognize complex driving
situations so always pay attention to
driving conditions and control your
vehicle speed.
NOTICE
The Smart Recuperation System may
not operate temporarily due to: • Electrical interference
• Modifying the suspension
• Differences of tire abrasion or tire
pressure
• Installing different type of tires

WARNING
• Driving on a curved road
OADAS014
OADAS016OADAS018
Forward Collision-Avoidance Assist
may not detect other vehicles,
pedestrians or cyclists in front of
you while driving on curved roads
adversely affecting the performance
of the sensors. This may result in no
warning, braking assist or steering
assist (if equipped) when necessary.
When driving on a curved road,
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.
