Driving your vehicle
Good Driving Practices
Never shift to P (Park) or N
(Neutral) to any other position with
the accelerator pedal depressed.
Never shift to P (Park) when the
vehicle is in motion.
Be sure the vehicle is completely
stopped before you attempt to shift
into R (Reverse) or D (Drive).
Do not shift to N (Neutral) when
driving. Doing so may result in an
accident.
Do not drive with your foot resting
on the brake pedal. Even light, but
consistent pedal pressure can
result in the brakes overheating,
brake wear and possibly even
brake failure.
Always apply the parking brake
when leaving the vehicle. Do not
depend on placing the gear in P
(Park) to keep the vehicle from
moving. Exercise extreme caution when
driving on a slippery surface. Be
especially careful when braking,
accelerating or shifting gears. On a
slippery surface, an abrupt change
in vehicle speed can cause the
drive wheels to lose traction and
may cause loss of vehicle control
resulting in an accident
Optimum vehicle performance and
economy is obtained by smoothly
depressing and releasing the
accelerator.
To reduce the risk of SERIOUS
INJURY or DEATH:
ALWAYS wear your seat belt.
In a collision, an unbelted
occupant is significantly more
likely to be seriously injured
or killed than a properly belt-
ed occupant.
Avoid high speeds when cor-
nering or turning.
WARNING
Do not make quick steering
wheel movements, such as
sharp lane changes or fast,
sharp turns.
The risk of 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.
HYUNDAI recommends you
follow all posted speed limits.

5-17
Driving your vehicle
The paddle shifter is used to adjust
the regenerative braking rate from 0
to 3 during decelerating or braking.
Left side ( ): Increases regener-
ative braking and deceleration.
Right side ( ): Decreases
regenerative braking and decelera-
tion.
Pull and hold the left side paddle
shifter to change to 0.
Pull and hold the left side paddle
shifter to change to 3.
Information
The paddle shifter does not operate
when:
• Both Paddle shifters are pulled at
the same time.
• The Smart Cruise Control system is
activated.
• The vehicle is shifted to P (Park), R
(Reverse) and N (Neutral).
If the battery is fully charged when
descending down a long or steep
hill, the regenerative braking is
not working even though operat-
ing the paddle shifter. In this case,
depress the brake pedal to brake
the vehicle. This is normal and
does not indicate a problem with
your paddle shifter and brakes.The selected regenerative braking
rate is displayed on the instrument
cluster.
What Does Regenerative
Braking Do?
It uses the electric motor when
decelerating or braking which trans-
forms vehicle motion (kinetic energy)
to electrical energy to charge the
high voltage batteries.

Power Brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
If the power is not supplied such as
battery discharge, 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, how-
ever, will be longer than with power
brakes.
Do not pump the brake pedal when
the power assist has been interrupt-
ed.

Driving your vehicle
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 stopping
distances.
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.
Wet brakes may impair the
vehicle's ability to safely slow
down; the vehicle may also
pull 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 heat
up the brakes while maintain-
ing a safe forward speed until
brake performance returns to
normal. Avoid driving at high
speeds until the brakes func-
tion correctly.WARNING

Do not continue depressing the
brake 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 depressed
suddenly.
- 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 may
hear 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 worn
brake pads.
Information
Always replace brake pads as com-
plete front or rear axle sets.
