components found in the interior
furnishings in a vehicle, contain or
emit harmful chemicals known to the
State of California to cause cancer and
birth defects and reproductive harm.
In addition, certain fluids contained
in vehicles and certain products of
components contain or emit chemicals
known to the State of California to
cause cancer and birth defects or other
reproductive harm.
Before Entering the Vehicle
• Be sure all windows, outside mirror(s),
and outside lights are clean and
unobstructed.
• Remove frost, snow, or ice.
• Visually check the tires for uneven
wear and damage.
• Check under the vehicle for any sign
of leaks.
• Be sure there are no obstacles behind
you if you intend to back up.
Before Starting
• Make sure the hood, the liftgate, and
the doors are securely closed and
locked.
• Adjust the position of the seat and
steering wheel.
• Adjust the inside and outside rearview
mirrors.
• Verify all the lights work.
• Fasten your seat belt. Check that all
passengers have fastened their seat belts.
• Check the gauges and indicators
in the instrument panel and the
messages on the instrument display
when the vehicle is in the ON position. •
Check that any items you are carrying
are stored properly or fastened down
securely.
WARNING
To reduce the risk of SERIOUS INJURY or
DEATH, take the following precautions: • ALWAYS wear your seat belt. All
passengers must be properly belted
whenever the vehicle is moving.
For more information, refer to “Seat
Belts” section in chapter 3.
• Always drive defensively. Assume
other drivers or pedestrians may be
careless and make mistakes.
• Stay focused on the task of driving.
Driver distraction can cause
accidents.
• Leave plenty of space between you
and the vehicle in front of you.
WARNING
NEVER drink or take drugs and drive. Drinking or taking drugs and driving
is dangerous and may result in an
accident and SERIOUS INJURY or
DEATH. Drunk driving is the number one
contributor to the highway death
toll each year. Even a small amount
of alcohol will affect your reflexes,
perceptions and judgment. Just
one drink can reduce your ability to
respond to changing conditions and
emergencies and your reaction time
gets worse with each additional drink.
Driving while under the influence
of drugs is as dangerous or more
dangerous than driving under the
influence of alcohol.
You are much more likely to have a
serious accident if you drink or take
drugs and drive. If you are drinking or
taking drugs, don’t drive. Do not ride
with a driver who has been drinking
or taking drugs. Choose a designated
driver or call a taxi.

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.

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
