Driving your vehicle
Good Driving Practices
Never move the shift lever from P
(Park) or N (Neutral) to any other
position with the accelerator pedal
depressed.
Never move the shift lever into 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 move the shift lever to N
(Neutral) when driving. If the shift
lever is moved to N (Neutral) while
driving, the vehicle loses the ability
to provide engine braking. Doing
so may increase the risk of an acci-
dent. Also, moving the shift lever
back to D (Drive) while the vehicle
is moving may severely damage
the transmission.
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. Depressing both accelerator and
brake pedals at the same time can
trigger logic for engine power
reduction to assure vehicle decel-
eration. Vehicle acceleration will
resume after the brake pedal is
released.
When driving in Manual Shift
Mode, slow down before shifting to
a lower gear. Otherwise, the lower
gear may not be engaged if the
engine rpms are outside of the
allowable range.
Always apply the parking brake
when leaving the vehicle. Do not
depend on placing the transmis-
sion 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.

Regen B mode
The paddle shifter is used to adjust
the regenerative braking level from 0
to 3 when the vehicle is in ECO
mode.
Left side (-): Increases the regen-
erative braking level and decelera-
tion.
Right side (+): Decreases the
regenerative braking level and
deceleration.
Information
• The Regen B function starts from
level 0 when starting your vehicle
and the system works only in D
(Drive).
• The Regen B function is cancelled
when the vehicle is shifted to the P
(Park), R (Reverse), N (Neutral) and
Sport mode.
• The Regen B function is cancelled
while ABS (Anti-lock Braking
System) and ESC (Electronic
Stability Control) is operating.
• Deceleration differences occur even
in the same system level according
to driving speeds (You may recog-
nize significant deceleration differ-
ences during city driving but you
may not feel differences while high
speed driving.)
Information
The paddle shifter does not operate
when:
• Both 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.

Operating the paddle shifter will
not enable the vehicle to come
to a complete stop. Depress the
brake pedal to stop the vehicle
completely.
CAUTION
The Regen B function may not
operate depending on the
motor's chargeable state (over
charged, high temperature or
low temperature). Always pay
attention to road and driving
conditions, while driving. If nec-
essary, depress the brake pedal
to reduce your driving speed.
WARNING

5-26
Driving your vehicle
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.

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, move the
gear shift lever to Manual
Shift Mode and manually
downshift to a lower gear in
order to control your speed
without using the brake pedal
excessively. Applying the
brakes continuously will
cause the brakes to overheat
and could result in a tempo-
rary loss of braking perform-
ance.
(Continued)
(Continued)
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 depress the brake pedal
continuously without the " "
indicator ON. The battery may be
discharged.
Some noise and vibration may
occur during braking. This is
normal.
In below cases, some electric
brake pump noise and motor
vibration may occur temporarily.
This is normal operation.
- When the pedal is depressed
very quickly
- When the pedal is depressed
multiple times in short inter-
vals
- When the ABS function is acti-
vated during 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.
Parking Brake
(foot type, if equipped)
Always set the parking brake before
leaving the vehicle. To apply the
parking brake:
Firmly depress the brake pedal.
Depress the parking brake pedal
down as far as possible.

Whenever leaving the vehicle
or parking, always come to a
complete stop and continue to
depress the brake pedal. Move
the shift lever into P (Park)
position, then apply the park-
ing brake, and place the
Engine Start/Stop button in
the OFF position.
Vehicles with the parking
brake not fully engaged are at
risk for moving inadvertently

or others.
NEVER allow anyone who is
unfamiliar with the vehicle to
touch the parking brake. If the
parking brake is released
unintentionally, serious injury
may occur.
Only release the parking
brake when you are seated
inside the vehicle with your
foot firmly on the brake pedal.
WARNING
To reduce the risk of SERIOUS
INJURY or DEATH, do not oper-

Do not apply the accelerator
pedal while the parking brake is
engaged. If you depress the
accelerator pedal with the park-
ing brake engaged, warning will
sound. Damage to the parking
brake may occur.
Driving with the parking brake
on can overheat the braking sys-
tem and cause premature wear
or damage to brake parts. Make
sure the parking brake is
released and the Brake Warning
Light is off before driving.Check the Parking
Brake Warning Light
by placing the Engine
Start/Stop button to
the ON position (vehi-
cle not in the ready

This light will be illuminated when the
parking brake is applied with the
Engine Start/Stop button in the
START or ON position.
Before driving, be sure the parking
brake is released and the Brake
Warning Light is OFF.
If the Parking Brake Warning Light
remains on after the parking brake is
released while the vehicle is in the
ready ( ) mode, 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 con-
tinue to drive the vehicle until you
can reach a safe location.
