Features of your vehicle
Electric power steering (EPS)
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 the power steering control
unit which senses the steering wheel
torque and vehicle speed to com-
mand 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 EPS warning light does not
illuminate.
• The steering effort is increased immediately after turning the igni-
tion switch or ENGINE
START/STOP button to the ON
position. This happens as the sys-
tem 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 or ENGINE
START/STOP button to the ON or
OFF position.
• Motor noise may be heard when the vehicle is at a stop or at a low
driving speed. (Continued)(Continued)
• When abnormality is detected in
the electric power steering system,
to prevent a deadly accident, the
steering assist function will stop.
At this time, the warning light
turns on or blinks on the cluster.
The steering wheel may become
difficult to control or operate.
Have your vehicle checked imme-
diately, after moving the vehicle to
a safe zone.
• The steering effort increases if the steering wheel is rotated continu-
ously when the vehicle is not in
motion. However, after a few min-
utes, it will return to its normal
condition.
• When you operate the steering wheel in low temperature, noise
may occur. If the temperature
rises, the noise will likely disap-
pear. This is a normal condition.
• When the charging system warn- ing light comes on or the battery
voltage is low (when the alternator
or battery does not operate nor-
mally), the steering wheel may get
heavy and become difficult to con-
trol or operate abnormally.

Charging System
Warning Light
This warning light illuminates:
 When there is a malfunction with either the alternator or electrical
charging system.
If there is a malfunction with either
the alternator or electrical charging
system:
1. Drive carefully to the nearest safe location and stop your vehicle.
2. Turn the engine off and check the alternator drive belt for looseness
or breakage.
If the belt is adjusted properly,
there may be a problem in the
electrical charging system.
In this case, have your vehicle
inspected by an authorized Kia
dealer as soon as possible.
Engine Oil Pressure Warning Light
This warning light illuminates:
 When the engine oil pressure is low.
 Drive carefully to the nearest safe location and stop your vehicle.
 Turn the engine off and check the engine oil level (For more details,
refer to “Engine Oil” in chapter 7). If
the level is low, add oil as required.
 If the warning light remains on after adding oil or if oil is not available,
have your vehicle inspected by an
authorized Kia dealer as soon as
possible. Continued driving with
the warning light on may cause
engine failure.
CAUTION - Malfunction
Indicator Lamp (MIL)
Driving with the Malfunction Indicator Lamp (MIL) on maycause damage to the emissioncontrol systems, which couldaffect drivability and/or fueleconomy.
CAUTION
If the Malfunction IndicatorLamp (MIL) illuminates, poten-tial catalytic converter damageis possible, which could resultin loss of engine power.
In this case, have your vehicleinspected by an authorized Kiadealer as soon as possible.

when the engine and radiator
are hot. Scalding hot coolant
and steam may blow out under
pressure which may result in
serious injury.
CAUTION
Put a thick cloth or fabric around the radiator cap beforerefilling the coolant in order toprevent the coolant from over-flowing into engine parts suchas the alternator.
