Regenerative Braking
(Paddle Shifter)
The paddle shifter is used to adjust
the regenerative braking level from 0
to 3 during decelerating or braking.
Left side [-] : Increases regenera-tive braking and deceleration.
Right side [+] : Decreases regener- ative braking and deceleration.
✽ ✽
NOTICE
• The control level will be started at
0 when the engine start. It will
activate only in D (Drive) range.
• If you operate the shift lever (to P, R, N/Sport), Regen B mode will be
cancelled and if you return to D
(Drive) range, the Regen B mode
will be returned to 0 level.
• Regen B mode will be cancelled when ABS, ESC operate.
• The speed decrement may differ- ent depends on the vehicle speed
even in the same Regen B level.
(The speed decrement in each level
is bigger in the city driving than
that of highway driving.)
✽ ✽
NOTICE
The vehicle does not completely stop
by using paddle shifter lever. When
the Regen B power reduced, the
vehicle slowly moves about 10 km/h.
In order to stop the vehicle, depress
the brake pedal.
✽ ✽
NOTICE
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.
• Cruise Control system or Cruise Control system is activated.
REGENERATIVE BRAKING SYSTEM
ODEP059294
WARNING
Usage of the regenerative brak-
ing function may be limited
according to the battery and
motor’s condition. (over charge,
high and low temperature)
Check traffic and driving condi-
tions. If necessary, control the
vehicle speed by using the
brake pedal.

Power brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
If the hybrid system is not on 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 dis-
tance, however, will be longer than
with power brakes.
When the hybrid system is not on,
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.
BRAKE SYSTEM
WARNING- Steep hill
braking
Avoid continuous application of
the brakes when descending a
long or steep hill by shifting to a
lower gear. Continuous brake
application may cause the
brakes to overheat and could
result in a temporary loss of
braking performance.
WARNING- HEV driving down hill
Do not turn off the Hybrid sys-
tem while going down a hill. The
brake booster may not work
sufficiently and the braking dis-
tance may be longer.CAUTION- Brake Pedal
Do not drive with your foot rest- ing on the brake pedal. This willcreate abnormally high braketemperatures which can causeexcessive brake lining and padwear.

531
Driving your vehicle
Wet brakes may impair the vehicle’s
ability to safely slow down; the vehi-
cle 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, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.
✽ ✽NOTICE
Do not depress the brake pedal con-
tinuously without the “ ” indica-
tor ON. The battery may be dis-
charged.
In the event of brake failure
If service brakes fail to operate while
the vehicle is in motion, you can
make an emergency stop with the
parking brake. The stopping dis-
tance, however, will be much greater
than normal.
Disc brakes wear indicator
When your brake pads are worn and
new pads are required, you will hear
a high-pitched warning sound from
your front brakes or rear brakes. You
may hear this sound come and go or
it may occur whenever you depress
the brake pedal.
Please remember that some driving
conditions or climates may cause a
brake squeal when you first apply (or
lightly apply) the brakes. This is nor-
mal and does not indicate a problem
with your brakes.
Always replace the front or rear
brake pads as pairs.
WARNING- Parking
brake
Avoid applying the parking
brake to stop the vehicle while it
is moving except in an emer-
gency situation. Applying the
parking brake while the vehicle
is moving at normal speeds can
cause a sudden loss of control
of the vehicle. If you must use
the parking brake to stop the
vehicle, use great caution in
applying the brake.
CAUTION- Replace brake pads
Do not continue to drive withworn brake pads. Continuing todrive with worn brake pads candamage the braking system andresult in costly brake repairs.

Parking brake – Foot type
Applying the parking brake
To engage the parking brake, first
apply the foot brake and then
depress the parking brake pedal
down as far as possible.
Releasing the parking brake
To release the parking brake,
depress the parking brake pedal a
second time while applying the foot
brake. The pedal will automatically
extend to the fully released position.
WARNING- Brake wear
Do not ignore high pitched wear
sounds from your brakes. If you
ignore this audible warning, you
may eventually lose braking
performance, which could lead
to a serious accident.
ODE056015
ODE056014
CAUTION - Parking brake
Driving with the parking brake applied will cause excessivebrake pad (or lining) and brakerotor wear.

533
Driving your vehicle
Check the brake warning light by turn-
ing the ignition switch or ENGINE
START/STOP button ON (do not start
the engine). This light will be illuminat-
ed when the parking brake is applied
with the ignition switch or ENGINE
START/STOP button in the START or
ON position.
Before driving, be sure the parking
brake is fully released and the brake
warning light is off.
If the brake warning light remains on
after the parking brake is released
while the engine is running, there may
be a malfunction in the brake system.
Immediate attention is necessary.If at all possible, cease driving the
vehicle immediately. If that is not pos-
sible, use extreme caution while
operating the vehicle and only contin-
ue to drive the vehicle until you can
reach a safe location or repair shop.
WARNING - Parking brake
use
Never allow a passenger to touch the parking brake. If the
parking brake is released
unintentionally, serious injury
may occur.
All vehicles should always have the parking brake fully
engaged when parked to avoid
inadvertent movement of the
vehicles which can injure
occupants or pedestrians.
