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

Your vehicle speed can be reduced
due to a vehicle in the adjacent lane.
Apply the accelerator pedal and
select the appropriate speed. Checkto be sure that the road conditions
permit safe operation of the Smart
Regeneration System.
On inclines
When coasting on an uphill or down-
hill, the system may not detect the
vehicle in your lane and the regener-
ative braking level will reduce auto-
matically, 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.
Lane changing
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 immedi- ately when a vehicle cuts in sud-
denly. Always pay attention to the
traffic, road and driving conditions.

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

5-26
Driving your vehicle
Do not continue depressing thebrake pedal if the " "indica-
tor 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 depressedsuddenly.
- When the pedal is repeatedly depressed in short intervals.
- When the ABS function is acti- vated while braking.
Disc Brake Wear Indicator
When your brake pads are worn and
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.
Information
Always replace brake pads as com-
plete front or rear axle sets.
Electronic Parking Brake (EPB)
Applying the parking brake
To apply the EPB (Electronic
Parking Brake):
1. Depress the brake pedal.
2. Pull the EPB switch upwards.
Make sure the Parking Brake
Warning Light comes on.
With the AUTO HOLD feature
enabled, the EPB is automatically
applied when the vehicle is shut off.

2. Fasten the driver's seat belt.
3. Close the driver's door, hood and tailgate.
4. Depress the accelerator pedal while the gear is in D (Drive) or
R (Reverse).
The Parking Brake Warning Light
should be turned off when the EPB isreleased.
To reduce the risk of SERIOUS
INJURY or DEATH, do not oper-ate the parking brake while the
vehicle is moving except in an
emergency situation. It could
damage the brake system andlead to an accident.

up the vehicle.
If the parking brake warning light is still on even though the EPB
has been released, have the sys-
tem checked an authorized
HYUNDAI dealer.
Do not drive your vehicle with the EPB applied. It may cause
excessive brake pad and brake
rotor wear.EPB (Electronic Parking Brake)

NOTICE
To prevent unintentional move-
ment when stopped and leav-
ing the vehicle, do not use the
P (Park) position in place of the
parking brake. Set the parkingbrake and make sure the vehi-
cle is securely positioned in P
(Park).
Never allow anyone who is
unfamiliar with the vehicle to
touch the parking brake. If theparking brake is released
unintentionally, serious injury
may occur.
All vehicles should always
have the parking brake fully
engaged when parking to
avoid inadvertent movement
of the car which can injureoccupants or pedestrians.
