"Smart Recuperation System".
Information
The paddle shifter does not operate when:

[The [
] and [] paddle shifters are
pulled at the same time.

[The vehicle is decelerating by
depressing the brake pedal.

[The Cruise Control system or Smart
Cruise Control system is activated.

[Selecting 0 step of the regenerative
braking system, the brake disc cleaning
function is operated around 10 times.
While operating to clean the brake
disc, the driving distance and the
regenerative braking performance
can be reduced. After finishing, the
regenerative braking performance will
be restored.
Information
2WD Long Range vehicles default to level
3 regenerative braking whenever the
vehicle is turned on.
Information
The regenerative braking system on 2WD
Long Range vehicles defaults to Level 3
(L3) in order to maximize vehicle’s all
electric range. This setting will default
to Level 3 (L3) whenever the vehicle is
turned ON. Driver is able to adjust the
regenerative system to their preference
after each vehicle start, but it will only
remain until the vehicle is shut down.

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.

Radar)
ONE1071018
[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

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
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

When All Wheel Drive(AWD) is
activated, driving forces are distributed
appropriately to front and rear wheels.
It could improve driving performance by
maximizing the driving force of vehicles
on severe road conditions such as steep
hills, unpaved, slippery, etc.
Advantage of electronic AWD
1. Improvement of straight stability
2. Improvement of driving performance
on curve
3. Secure stability on severe condition
such as wet and sandy roads.
4. Improvement of energy efficiency
from driving mode automatic control.
Information
AWD vehicles could change the
engagement status of the motor according
to the situation required. Auto changing
the driving mode(2WD/AWD)helps
improve energy efficiency and driving
stability.
WARNING
To reduce the risk of SERIOUS INJURY
or DEATH:

[Avoid high speeds when cornering or
turning.

[Do not make quick steering wheel
movements, such as sharp lane
changes or fast, sharp turns.

[The risk of a rollover is greatly
increased if you lose control of your
vehicle at highway speeds.

[Loss of control often occurs if two or
more wheels drop off the roadway
and the driver over steers to reenter
the roadway.

[In the event your vehicle leaves
the roadway, do not steer sharply.
Instead, slow down before pulling
back into the travel lanes.
NOTICE

[Do not drive in water if the level
is higher than the bottom of the
vehicle.

[Check your brake condition once
you are out of mud or water. Depress
the brake pedal several times as you
move slowly until you feel normal
braking return.

[Shorten your scheduled
maintenance interval if you drive in
off-road conditions such as sand,
mud or water (see "Maintenance
Under Severe Usage Conditions"
section in chapter 9).

[Always wash your vehicle thoroughly
after off road use, especially the
bottom of the vehicle.

[Be sure to equip the vehicle with four
tires of the same size and type.

[Make sure that a full time AWD
vehicle is towed by a flat bed tow
truck.
