Electric power steering
Power steering uses the 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 motor driven power steering is
controlled by the power steering con-
trol unit which senses the steering
wheel torque and vehicle speed to
command the motor.
The steering wheel becomes heavier
as the vehicle’s speed increases and
becomes lighter as the vehicle’s
speed decreases for better control of
the steering wheel.
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.
✽ ✽
NOTICE
The following symptoms may occur
during normal vehicle operation:
• The steering effort is increased
immediately after turning the igni-
tion switch on. This happens as the
system performs the EPS system
diagnostics. When the diagnostics
are completed, the steering wheel
will return to its normal condition
• A click noise may be heard from the EPS relay after the ignition
switch is turned to the ON or
LOCK position.
• Motor noise may be heard when the vehicle is at a stop or at a low
driving speed.
• The steering effort increases if the steering wheel is rotated continuous-
ly when the vehicle is not in motion.
However, after a few minutes, it will
return to its normal conditions.
• When you operate the steering wheel in low temperature, abnor-
mal noise could occur. If tempera-
ture rises, the noise will disappear.
This is a normal condition.
If the Electric Power Steering System
does not operate normally, the warn-
ing light will illuminate on the instru-
ment cluster. The steering wheel may
become difficult to control or operate
abnormally. Take your vehicle to an
authorized Kia dealer and have the
vehicle checked as soon as possible.

BRAKE SYSTEM
Power brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
In the event that the power-assisted
brakes lose power because of a
stalled engine or some other reason,
you can still stop your vehicle by
applying greater force to the brake
pedal than you normally would. The
stopping distance, however, will be
longer.
When the engine is not running, 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.
To dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.
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.
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 detected changes in coeffi-
cient of friction between right wheels
and left wheels when braking.
VSM operation
When the vehicle stability manage-
ment is operating properly, you can
feel a slight pulsation in the vehicle.
This is only the effect of brake control
and indicates nothing unusual.The VSM does not operate when:
Driving on bank road such as gra-
dient or incline
Driving rearward
ESC OFF indicator light ( ) remains on the instrument
cluster
EPS indicator light remains on the instrument clusterVSM 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.
Malfunction indicator
The VSM can be deactivated even if
you don’t cancel the VSM operation
by pressing the ESC OFF button. It
indicates that a malfunction has
been detected somewhere in the
Electric Power Steering system or
VSM system. If the ESC indicator
light ( ) or EPS warning light
remains on, take your vehicle to an
authorized Kia dealer and have the
system checked.
The VSM is designed to functionabove approximately 9 mph (15
km/h) on curves.
The VSM is designed to function above approximately 18 mph (30
km/h) when a vehicle is braking on
a split-mu road. The split-mu road
is made of surfaces which have dif-
ferent friction forces.
