Checking the warning lights
Check the cause of the warning lights referring to the table below and take appropriate
measures.
Warning LightCauseMeasure
Service warning light This warning light illuminates:
• When there is a problem with
related parts of the electric
vehicle control system, such
as sensors, etc.
• When an actuator, electric compressor for air
conditioning, etc.
malfunctions. In a normal condition, it
illuminates for about 3 seconds
when the Start/Stop button is in
the ON position and then goes
off.
• When the warning light
illuminates while driving, or
does not go off after starting
the vehicle, have your vehicle
inspected by an authorized
HYUNDAI dealer.
Power down indicator light This warning light illuminates:
• When the high voltage
battery level is too low or
voltage is decreasing.
(Output limit occurs when the
charge level is insufficient.)
• When the temperature of the high voltage battery is too
high or too low.
• When the driving system temperature is overheated
and requires protection. If it illuminates alone, it is not
failure.
• If both Power down indicator
light and Service warning
light illuminate at the same
time, have the vehicle
inspected by an authorized
HYUNDAI dealer.
• When the indicator is illuminating, immediately
charge the vehicle. The
driving speed may be limited
and the vehicle may not
properly drive uphill.
High voltage battery level warning light This warning light illuminates
when the high voltage battery
level is low. Immediately charge the
vehicle. The vehicle can drive
an additional 18-31 mi. (30-50
km).
• The actual distance to empty
depends on the driving
conditions.
Regenerative brake warning light This warning light illuminates
when the regenerative brake
does not operate and the brake
does not perform well due to
the malfunction of the brake
system. Drive safely and have your
vehicle inspected by an
authorized HYUNDAI dealer.
• The operation of the brake
pedal may feel deeper than
normal or the braking
distance may increase.

Front airbags are not designed to inflate
in rear collisions, because occupants are
moved backward by the force of the
impact. In this case, inflated airbags
would not provide any additional benefit.
B3003406
Front airbags may not inflate in side
impact collisions, because occupants
move in the direction of the collision, and
thus in side impacts, front airbag
deployment would not provide additional
occupant protection.
However, side and curtain airbags may
inflate depending on the severity of
impact.
B3003407
In an angled collision, the force of impact
may direct the occupants in a direction
where the airbags would not be able to
provide any additional benefit, and thus
the sensors may not deploy any airbags.
B3003408
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. Airbags may not inflate
in this “underride” situation because
deceleration forces that are detected by
sensors may be significantly reduced by
such “underride” collisions.

Low Tire Pressure Warning Light
WL_TPMSWarningLamp
This warning light illuminates:
• When the Start/Stop button is in the ON position. The low tire pressure warning
light illuminates for about 3 seconds
and then goes off.
• When one or more tires are significantly underinflated. (The location of the
underinflated tire appears on the
instrument cluster.)
For more information, refer to the “Tire
Pressure Monitoring System (TPMS)”
section in chapter 8.
This warning light remains ON after
blinking for about 60 seconds, or
repeatedly blinks ON and OFF in 3 second
intervals:
When there is a malfunction with the
TPMS.
If this occurs, have the vehicle inspected
by an authorized HYUNDAI dealer as soon
as possible.
For more information, refer to the “Tire
Pressure Monitoring System (TPMS)”
section in chapter 8.
WARNING • The TPMS cannot alert you to severe and sudden tire damage caused by
external factors.
• If you notice any vehicle instability, immediately take your foot off the
accelerator pedal, apply the brakes
gradually with light force, and slowly
move to a safe position off the road.

To adjust the regenerative braking level of
the smart regeneration system, go to
Setup > EV > Smart Regeneration
System from the infotainment system.
Pausing Smart Regeneration
System
The smart regeneration system is
temporarily turned off in the following
conditions. While the system is turned off,
the driver must keep eyes on the road and
depress the brake pedal to decelerate.
• The gear is shifted to N (Neutral), R
(Reverse) or P (Park)
• Smart Cruise Control is ON
• ESC (Electronic Stability Control) is operating
• ABS is operating
Front Sensors
B6003001(1) Front radar
(2) Front corner radar
Front sensors recognize the distance
from the vehicle ahead to control the
regenerative braking intensity. If the
sensor is covered with snow, rain, or other
foreign substances, the performance of
the sensors may deteriorate, and the
smart regeneration system may turn off.
Always keep the sensors clean.
System Check Message
B6003101
When the front radar is covered or
blocked, the smart regeneration system
may be temporarily disabled. The 'Check
Smart Regeneration System' warning
message may appear, and the
regenerative braking level is displayed on
the instrument cluster.
The system operates normally when such
foreign material is removed, and the
system is turned on by pulling and

holding the right paddle shifter ( ) for
over one second.
If the smart regeneration system does not
operate normally after the sensor has
been uncovered or unblocked, have the
vehicle inspected by an authorized
HYUNDAI dealer.
Smart Regeneration System
Precautions
• Always monitor the distance to vehicles ahead on the road. The smart
regeneration system is not a substitute
for safe driving practices, but a
supplemental function only.
• Always maintain a safe distance from the vehicles ahead and adjust your
vehicle speed to the road conditions.
The smart regeneration system may not
recognize unexpected and sudden
situations or complex driving
situations.
General precautions
• Always maintain a safe distance from the vehicles ahead and adjust your
vehicle speed depending on the road
conditions.
• Always prepare for unexpected situations and depress the brake pedal
to decelerate when necessary. The
smart regeneration system cannot
react to pedestrians, vehicles making a
sudden stop and vehicles coming from
the opposite lane.
• If the vehicle ahead frequently changes the lane, keep your eyes forward to be
prepared for hazardous situations. In
this case, the smart regeneration
system may respond late and may
inappropriately respond to vehicle
movements from the side lanes.
• The driver must depress the brake pedal when stopping the vehicle.
• Depress the brake pedal to decelerate in the following conditions when: - The front part of the vehicle is lifted
up because of the cargo loaded on
the rear part of the vehicle.
- You are operating the steering wheel.
- You are not driving in the center of the lane.
- You are driving on a narrow or curved road.
• The smart regeneration system may be temporarily turn off when exposed to
strong electromagnetic waves.
• If the vehicle starts coasting near the speed camera and engages the brake
with the smart regeneration system,
the vehicle may not be able to keep the
speed limit. Always comply with the
road and traffic law.
Sensor precautions
• Never disassemble the radar or radar assembly, and never apply any impact
on it.
• If there is impact on or near the radar, the sensors may be damaged or not be
properly aligned near the radar, even
though a warning message does not
appear on the instrument cluster, the
Smart Regeneration System may not
operate properly. Have the vehicle
inspected by an authorized HYUNDAI
dealer.
• If the radars have been replaced or repaired, have the vehicle inspected by
an authorized HYUNDAI dealer.
• Use only genuine parts to repair the bumper where the radar is located.
• Do not install a license plate frame or other objects such as bumper sticker,
film, bumper guard, or bumper wrap
near the radar.
• The Smart Regeneration System may not work properly if the bumper has
been replaced, or the surroundings of
the radar has been damaged or
painted.

Driving Your Vehicle
6-22
Driving on hills
B6003204
When coasting uphill or downhill, the
front sensors may not detect the vehicle
ahead or suddenly detect the vehicle
ahead at the end of the incline or at the
point where the incline changes. The
regenerative braking intensity is adjusted
automatically changing your vehicle
speed. Brake as needed to reduce your
driving speed.
Changing lanes
B6003205
• When a vehicle moves into your lane from an adjacent lane, it cannot be
detected by the sensors until it is in the
sensor's detection range.
• The smart regeneration system may not immediately detect the vehicle when
your vehicle changes lanes abruptly.
Braking System
Power-Assist Brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
In the event of a vehicle power failure, the
power assist for the brakes will not work.
You can still stop your vehicle, but it will
require greater force and increased pedal
travel than normal. The stopping
distance, however, will be longer than
with power brakes.
Information • When the brake pedal is depressed under certain driving conditions or weather
conditions, you may temporarily hear a
noise. This is normal and does not indicate
a problem with your brakes.
• While driving on a road with deicing chemicals, brake noise or abnormal tire
wear may occur due to deicing chemicals.
In a safe traffic condition, additionally
apply the brakes to remove deicing
chemicals on the brake discs and pads.

WARNING Take the following precautions:
• Do not drive with your foot resting on the brake pedal. This will create
abnormal high brake temperatures,
excessive brake lining and pad wear,
and increased stopping distances. So
increase the regeneration braking level
with the left paddle shifter to decrease
the speed.
• When descending down a long or steep hill, use the paddle shifter to increase
the regeneration braking level in order
to decrease your speed without using
the brake pedal excessively. Applying
the brakes continuously will cause the
