Electric Power Steering (EPS)
The power steering uses a motor to
assist you in steering the vehicle. If
the engine is off or if the power steer-
ing system becomes inoperative, the
vehicle may still be steered, but it will
require increased steering effort.
The electric power steering is con-
trolled by a power steering control
unit which senses the steering wheel
torque and vehicle speed to com-
mand the motor.
The steering becomes heavier as the
vehicle's speed increases and
becomes lighter as the vehicle's
speed decreases for improved steer-
ing control.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power
steering checked by an authorized
Kia dealer. If the Electric Power Steering
System does not operate normally,
the warning light will illuminate on
the instrument cluster. The steering
wheel may require increased
steering effort. Take your vehicle to
an authorized Kia dealer and have
the vehicle checked as soon as
possible.
When you operate the steering wheel in low temperature, noise
may occur. If temperature rises, the
noise will likely disappear. This is a
normal condition.
When the vehicle is stationary, and the steering wheel is turned all the
way to the left or right continuous-
ly, the steering wheel becomes
harder to turn. The power assist is
limited to protect the motor from
overheating.
As time passes, the steering wheel
will return to its normal condition.
✽ ✽ NOTICE
The following symptoms may occur
during normal vehicle operation:
• The EPS warning light does not
illuminate.
• The steering gets heavy immedi- ately after turning the Engine
Start/Stop button is ON position.
This happens as the system per-
forms the EPS system diagnostics.
When the diagnostics are complet-
ed, the steering system will return
to its normal condition.
• A click noise may be heard from the EPS relay after turning the
Engine Start/Stop button is ON or
OFF position.
• A motor noise may be heard when the vehicle is at a stop or at a low
driving speed. (Continued)

• If the Electronic Power SteeringSystem does not operate normally,
the warning light will illuminate or
flash on the instrument cluster. If
the power assistance of steering
fails, you will need to use more
force to steer.
Take your vehicle to an authorized
Kia dealer and have the vehicle
checked as soon as possible.
• When the charging system warning light comes on due to low voltage
(when the alternator or battery do
not operate normally or malfunc-
tions), the steering wheel may
require increased steering effort.Tilt and telescopic steering
Tilt and telescopic steering allows
you to adjust the steering wheel
before you drive. You can also raise it
to give your legs more room when
you exit and enter the vehicle.
The steering wheel should be posi-
tioned so that it is comfortable for
you to drive, while permitting you to
see the instrument panel warning
lights and gauges. To change the steering wheel angle,
pull down the lock-release lever (1),
adjust the steering wheel to the
desired angle (2) and height (3, if
equipped) then pull up the lock-
release lever to lock (4) the steering
wheel in place. Be sure to adjust the
steering wheel to the desired posi-
tion before driving.
WARNING- Steering
wheel adjustment
Never adjust the angle and
height of the steering wheel
while driving. You may lose
steering control.

✽ ✽NOTICE- Electronic Brake
force Distribution (EBD)
System Warning Light
When the ABS Warning Light is on
or both the ABS and the Parking
Brake & Brake Fluid Warning
Lights are on, the speedometer,
odometer, or tripmeter may not
work. Also, the EPS Warning Light
may illuminate and the steering
effort may increase or decrease.
In this case, have your vehicle inspect-
ed by an authorized Kia dealer as
soon as possible.
Regenerative Brake Warning Light
This warning light illuminates :
When the regenerative brake does
not operate and the brake does not
perform well. This causes the Brake
Warning light (red) and Regenerative
Brake Warning Light (yellow) to illu-
minate simultaneously.
In this case, drive safely and have
your vehicle inspected by an author-
ized Kia dealer.
Electronic PowerSteering (EPS) WarningLight
This warning light illuminates:
When the ignition is moved to ON, the warning light illuminates for
about 3 seconds and turns off
automatically if no problem.
When the warning light illuminates while driving, it indicates that there
is a problem with the electric power
steering system. In this case, have
your vehicle inspected by an
authorized Kia dealer.

Driving your vehicle
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.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.
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 will 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.

Vehicle stability management
(VSM)
This system provides further
enhancements to vehicle stability
and steering responses when a vehi-
cle is driving on a slippery road or a
vehicle detects changes in coeffi-
cient of friction between right wheels
and left wheels when braking.
VSM operation
When the VSM is in operation, ESC
indicator light ( ) blinks.
When the vehicle stability manage-
ment is operating properly, you can
feel a slight pulsation in the vehicle
and/or abnormal steering responses
(EPS- Electronic Power Steering).
This is only the effect of brake and
EPS control and indicates nothing
unusual.
The VSM does not operate when:
Driving on a sloping road such as agradient or incline
Driving in reverse
ESC OFF indicator light ( ) remains on the instrument cluster
EPS indicator light remains on the instrument cluster
VSM operation off
If you press the ESC OFF button to
turn off the ESC, the VSM will also
cancel and the ESC OFF indicator
light ( ) illuminates.
To turn on the VSM, press the button
again. The ESC OFF indicator light
goes out.
WARNING- Tire/
Wheel size
When replacing tires and wheels,
make sure they are the same size
as the original tires and wheels
installed. Driving with varying
tire or wheel sizes may diminish
any supplemental safety benefits
of the VSM system.WARNING- Vehicle stabili-
ty management
Drive carefully even though
your vehicle has vehicle stabili-
ty management. It can only
assist you in maintaining con-
trol of the vehicle under certain
circumstances.
