Features of your vehicle
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.
STEERING WHEEL

Features of your vehicle
Heated steering wheel
(if equipped)
With the ENGINE START/STOP but-
ton in the ON position, pressing the
heated steering wheel button warms
the steering wheel. The indicator on
the button will illuminate.
To turn the heated steering wheel off,
press the button once again. The
indicator on the button will turn off.
It will turn off automatically approxi-
mately 30 minutes after the heated
steering wheel is turned on.If you turn on the ignition again after
turning off your engine in half an
hour (after operating heater button),
the heating system will be main-
tained in its 'on' condition.
CAUTION
Do not install any grip to oper-
ate the steering wheel. Thiscauses damage to the heatedsteering wheel system.
When cleaning the heated steering wheel, do not use anorganic solvent such as paintthinner, benzene, alcohol andgasoline. Doing so may dam-age the surface of the steeringwheel.
If the surface of the steering wheel is damaged by a sharpobject, damage to the heatedsteering wheel componentscould occur.

Gauges
Speedometer
The speedometer indicates the for-
ward speed of the vehicle.
The speedometer is calibrated in
miles per hour and/or kilometers per
hour.
Engine coolant temperature gauge
This gauge shows the temperature
of the engine coolant when the igni-
tion switch is ON.
Do not continue driving with an over-
heated engine. If your vehicle over-
heats, refer to "If the engine over-
heats" in chapter 6.
If the gauge pointer moves beyond
the normal range area toward the "H"
position, it indicates overheating that
may damage the engine.
Fuel gauge
The fuel gauge indicates the approx-
imate amount of fuel remaining in the
fuel tank. The fuel tank capacity is
given in chapter 8. The fuel gauge is
supplemented by a low fuel warning
light, which will illuminate when the
fuel tank is nearly empty.
On inclines or curves, the fuel gauge
pointer may fluctuate or the low fuel
warning light may come on earlier
than usual due to the movement of
fuel in the tank.OTFH044053C

State of charge (SOC)
The state of charge (SOC) gauge
indicates the hybrid battery's charge
level. If the SOC is near L level, the
vehicle automatically operates the
engine to charge the battery.
However, if the service indicator and
MIL(Malfunction indicator lamp) turn
on when the State of Charge(SOC)
is near L(Low), have your vehicle
checked by an authorized Kia dealer
immediately.
WARNING- Fuel gauge
Stop and obtain additional fuel
as soon as possible after the
warning light comes on or when
the gauge indicator comes
close to the E level. Running out
of fuel can expose vehicle occu-
pants to danger.WARNING
Never try to start the vehicle if
the fuel tank is empty. The
engine is impossible to charge
the high voltage battery of
hybrid system. If you try to start
the vehicle when the fuel is
empty, the high voltage battery
will become discharged and be
damaged.
CAUTION- Low fuel
Avoid driving with extremely low fuel level. Running out offuel could cause the engine tomisfire, damaging the catalyticconverter.OTFH044057
