How to Operate
ONE1041017
Pulling the paddle-shift (
) for 1 or
more seconds, the smart recuperation
system will operate. The indicator of the
regenerative braking will be changed to
'AUTO' from the level indicator.
WARNING
The Smart Recuperation System which
automatically controls the regenerative
braking level when coasting is only a
supplemental system for the driver's
convenience. The system cannot
completely stop the vehicle nor avoid
all collisions. The brake control may
be insufficient depending on the
speed of the vehicle in front and when
the vehicle in front suddenly stops,
a vehicle cuts in suddenly and there
is a steep slope. Always look ahead
cautiously to prevent unexpected and
sudden situations from occurring.
Smart Recuperation System Will
Be Temporarily Cancelled When:
• Cancelled manually
Pulling and holding the right side
paddle shifter for more than 1 second.
The Smart Recuperation System turns
off temporarily and “AUTO” will be
replaced with regenerative braking
level indicator.
• Cancelled automatically
- The vehicle is shifted to N (Neutral), R (Reverse) or P (Park).
- Cruise Control system (including Smart Cruise Control system) is in
activation.
- The ESC (Electronic Stability Control) or ABS is operating.
WARNING
When the Smart Recuperation System
is cancelled automatically, adjust the
vehicle speed directly by depressing the
accelerator or brake pedal according to
the road condition ahead and driving
condition.
To Resume Smart Recuperation
System
To re-activate the Smart Recuperation
System while driving, pull and hold the

[2] : Front radar For detail location of sensor, refer to the picture
above.
In order for the Smart Recuperation
System to operate properly, always make
sure the radar sensor cover is clean and
free of dirt, snow, and debris. Dirt, snow,
or foreign substances on the lens may
adversely affect the sensing performance
of the sensor. In this case, the system
operation may stop temporarily and not
operate normally.
CAUTION
• Do not apply license plate frame or
foreign objects such as a bumper
sticker or a bumper guard near the
radar sensor. Doing so may adversely
affect the sensing performance of
the radar.
• Always keep the radar sensor and
lens cover clean and free of dirt and debris.
• Use only a soft cloth to wash the
vehicle. Do not spray pressurized
water directly on the sensor or
sensor cover.
• Be careful not to apply unnecessary
force on the radar sensor or sensor
cover. If the sensor is forcibly
moved out of proper alignment,
the Smart Recuperation System
may not operate correctly. In this
case, a warning message may not
be displayed. Have the vehicle
inspected by an authorized HYUNDAI
dealer.
• If the front bumper becomes
damaged in the area around the
radar sensor, the Smart Recuperation
System may not operate properly.
Have the vehicle authorized
HYUNDAI dealer.
• Use only genuine parts or the
equivalent specified for your vehicle
to repair or replace a damaged
sensor or sensor cover. Do not apply
paint to the sensor cover.

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

Driving Your Vehicle
6-26
Power-Assist Brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal usage.
If the vehicle is not running or is turned
off while driving, the power assist for
the brakes will not work. You can still
stop your vehicle by applying greater
force to the brake pedal than typical.
The stopping distance, however, will be
longer than with power brakes.
When the vehicle is not running, the
reserve brake power is partially depleted
each time the brake pedal is applied.
Do not pump the brake pedal when the
power assist has been interrupted.
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 shift lever
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 brakes to overheat and could
result in a temporary loss of braking
performance.
• Wet brakes may impair the vehicle's
ability to safely decelerate. Because
wet brakes increase braking distance
and cause noise troubles, select 0
step of the regenerative braking
system and depress the brake pedal
around 10 times, with keeping the
safe distance from other vehicles,
lightly in order to dry the braking
system. Such procedure may
decrease the driving distance by
restraining the regenerative braking
system, which is not a system
malfunction. Inspect the braking
system after car wash or driving over
wet road conditions.
NOTICE
• Do not continue depressing
the brake pedal if the ""
indicator is OFF. The battery may be
discharged.
• Noise and vibration generated
during braking is normal.
• Under normal operation, electric
brake pump noise and motor
vibration may occur temporarily in
below cases.
- When the pedal is depressed
suddenly.
- When the pedal is repeatedly
depressed in short intervals.
- When the ABS function is activated
while braking.
