Driving your vehicle
If the front radar recognizes the vehi-
cle in front, 'AUTO' is displayed in
blue. The regenerative braking levelis automatically controlled depend-
ing on the driving condition of the
vehicle in front and the level is indi-
cated with arrows.
However, current regenerative brak-
ing level is maintained if the driver
depresses the brake pedal while the
system is in activation. Also, the sys-
tem is cancelled temporarily if the
accelerator pedal is depressed.
Cancelling the Smart
Regeneration System:
Cancelled manuallyPulling and holding the right side
paddle shifter for more than 1 sec-ond.
The Smart Regeneration System
turns off temporarily. Note that the
"AUTO" indicator in the LCD dis-
play turns off.
Cancelled automatically - The vehicle is shifted to N(Neutral), R (Reverse) or P
(Park).
- The Cruise Control System (including the Smart Cruise
Control system) is enabled.
- The ESC (Electronic Stability Control) or ABS is activated.

OAEE049671L The Smart Regeneration
System which automatically
controls the regenerative brak-
ing level when coasting is only
a supplemental system for the
driver's convenience. The sys-
tem cannot completely stop the
vehicle nor avoid all collisions.
The brake control may be insuf-ficient depending on the speed
of the vehicle in front and when
the vehicle in front suddenly
stops, a vehicle cuts in sudden-
ly or there is a steep slope.
Always look ahead cautiously
to prevent unexpected and sud-
den situations from occurring.
WARNING

Resuming the Smart
Regeneration System
To re-activate the Smart
Regeneration System while driving,
pull and hold the right side paddle
shifter for more than 1 second again.
Note that the "AUTO" indicator in the
LCD display turns back on, signaling
that the Smart Regeneration System
is enabled again.
Disabling the Smart
Regeneration System

Vehicle-to-Vehicle Front
Recognition - Front RadarSensor
In order for the Smart Regeneration
System to operate properly, always
make sure the radar sensor cover is
clean and free of dirt, snow, and
debris. Dirt, snow, or foreign sub-
stances 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.
Driving your vehicle

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 adverse-
ly affect the sensing perform-
ance 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 pres-
surized water directly on the
sensor or sensor cover.
Be careful not to apply unnec-
essary force on the radar sen-
sor or sensor cover. If the sen-
sor is forcibly moved out of
proper alignment, the Smart
Regeneration 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
Regeneration System may not
operate properly. Have the
vehicle inspected by an
authorized HYUNDAI dealer.
Use only genuine HYUNDAI
parts to repair or replace a
damaged sensor or sensor
cover. Do not apply paint to
the sensor cover.
CAUTION
When the Smart Regeneration System is cancelled automati-
cally, adjust the vehicle speed
directly by depressing theaccelerator or brake pedal
according to the road conditionahead and driving condition.

Warning Message
Check Smart Regeneration System
The message will appear when the
system is not functioning normally.
The system will be disabled and the
"AUTO" indicator in the LCD display
will be turned off. 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 vehi-
cle to an authorized HYUNDAI deal-
er and have the system checked.
Limitations of the System
The Smart Regeneration 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 uninten-
tionally.
On curves
When coasting on the curve, the sys-
tem may not detect the vehicle in
your lane and the regenerative brak-
ing level will reduce automatically,
making you feel that the vehicle is
accelerating.
Also, if the system suddenly recog-
nizes the vehicle in front, the regen-
erative braking level will increase
automatically, making you feel that
the vehicle is decelerating.
The driver must maintain a safe brak-
ing distance, and if necessary,
depress the brake pedal to reduce
your driving speed in order to main-
tain a safe distance.5

Vehicle recognition
Some vehicles in your lane cannot
be recognized by the sensor:
- Narrow vehicles such as motorcy-cles or bicycles
- Vehicles offset to one side
- Slow-moving vehicles or sudden- decelerating vehicles
- Stopped vehicles (When the vehi- cle 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 recog-
nized 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 operat- ing
- When driving to one side of the lane
- When driving on narrow lanes or on curves
Apply the brake or accelerator pedal
if necessary.5
OAD058173N When using the Smart
Regeneration System take the
following precautions:
If an emergency stop is nec-
essary, you must apply thebrakes.
Keep a safe distance accord-
ing to road conditions and
vehicle speed. If the vehicle-
to-vehicle distance is too
close and the brakes are sud-
denly applied, a serious colli-
sion may result.
Always maintain sufficient braking distance and deceler-
ate your vehicle by applying
the brakes if necessary.
The Smart Regeneration
System cannot recognize a
stopped vehicle, pedestrians
or an oncoming vehicle.
Always look ahead cautiously
to prevent unexpected and
sudden situations from occur-ring.

Power Brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
If the vehicle is not in the ready
( ) mode or the vehicle 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 in the ready
( ) mode, 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.
Pump the brake pedal only when
necessary to maintain steering con-
trol on slippery surfaces.
BBRRAA KKIINN GG SS YY SSTT EEMM
Take the following precautions:
Do not drive with your foot resting on the brake pedal.This will create abnormal high
brake temperatures, exces-sive brake lining and pad
wear, and increased stoppingdistances.
When descending down a
long or steep hill, use the pad-
dle shifter (left side lever) to
increase regenerative braking
control in order to control
your speed without using the
brake pedal excessively.
Applying the brakes continu-
ously will cause the brakes to
overheat and could result in a
temporary loss of braking per-
formance.
(Continued)
(Continued)
Wet brakes may impair the
vehicle's ability to safely slow
down; the vehicle may alsopull to one side when the
brakes are applied. Applying
the brakes lightly will indicate
whether they have been
affected in this way. Always
test your brakes in this fash-
ion after driving through deep
water. To dry the brakes, light-
ly tap the brake pedal to heatup the brakes while maintain-
ing a safe forward speed until
brake performance returns to
normal. Avoid driving at highspeeds until the brakes func-
tion correctly.
WARNING

new pads are required, you will hear
a high pitched warning sound from
your front or rear brakes. You mayhear this sound come and go or it
may occur whenever you depress
the brake pedal.
Note that some driving conditions or
climates may cause a brake squeal
when you first apply (or lightly apply)
the brakes. This is normal and does
not indicate a problem with your
brakes.
To avoid costly brake repairs, do
not continue to drive with wornbrake pads.
