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.)
✽ ✽

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 with
worn brake pads. Continuing to
drive with worn brake pads can
damage the braking system and
result in costly brake repairs.

✽
✽
NOTICE
When you jump start your vehicle
because of a drained battery, the
engine may not run as smoothly and
the ABS warning light may turn on at
the same time. This happens because
of low battery voltage. It does not
mean your ABS has malfunctioned.
• Do not pump your brakes!
• Have the battery recharged before
driving the vehicle.
Electronic Stability Control
(ESC)
The Electronic Stability Control
(ESC) system is designed to stabi-
lize the vehicle during cornering
maneuvers. ESC checks where you
are steering and where the vehicle is
actually going. ESC applies the
brakes on individual wheels and
intervenes with the engine manage-
ment system to stabilize the vehicle.
Electronic stability control (ESC) will
not prevent accidents. Excessive
speed in turns, abrupt maneuvers
and hydroplaning on wet surfaces
can still result in serious accidents.Only a safe and attentive driver can
prevent accidents by avoiding
maneuvers that cause the vehicle to
lose traction. Even with ESC
installed, always follow all the normal
precautions for driving - including
driving at safe speeds for the condi-
tions.
ODEP059016
WARNING
For maximum protection, always
wear your seat belt. No system,
no matter how advanced, can
compensate for all driver error
and/or driving conditions.
Always drive responsibly.

Use high quality ethylene gly-
col coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because
it helps prevent corrosion in the cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 8. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in chapter 8. The level of charge in
your battery can be checked by an
authorized Kia dealer or a service
station.
Change to "winter weight" oil
if necessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
chapter 9 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
Kia dealer.
Check spark plugs and ignition
system
Inspect your spark plugs as
described in chapter 8 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked, worn or
damaged in any way.
To keep locks from freezing
To keep the locks from freezing,
squirt an approved de-icer fluid or
glycerine into the key opening. If a
lock is covered with ice, squirt it with
an approved de-icing fluid to remove
the ice. If the lock is frozen internally,
you may be able to thaw it out by
using a heated key. Handle the heat-
ed key with care to avoid injury.
Use approved window washer
anti-freeze in system
To keep the water in the window
washer system from freezing, add an
approved window washer anti-freeze
solution in accordance with instruc-
tions on the container. Window wash-
er anti-freeze is available from an
authorized Kia dealer and most auto
parts outlets. Do not use engine
coolant or other types of anti-freeze
as these may damage the paint fin-
ish.
