Battery Type: CR2032
To replace the battery:
1. Remove the mechanical key.
2. Use a slim tool to pry open the rear
cover of the smart key.
3. Remove the old battery and insert the
new battery. Make sure the battery
position is correct.
4. Reinstall the rear cover of the smart
key.
If you suspect your smart key might have
sustained some damage, or you feel
your smart key is not working correctly,

Information
An inappropriately disposed battery can be harmful to the
environment and human health.
Dispose of the battery according
to your local law(s) or regulation.
Immobilizer System
The immobilizer system protects your
vehicle from theft. If an improperly
coded key (or other device) is used, the
engine’s fuel system is disabled.
When the ignition switch is placed in
the ON position, the immobilizer system
indicator should come on briefly, then
go off. If the indicator starts to blink, the
system does not recognize the coding of
the key.
Turn the ignition switch to the LOCK/OFF
position, then turn the ignition switch to
the ON position again.
In some circumstances, the vehicle may
not recognize your smart key if another
smart key device is nearby or a metal
object such as a key chain is causing
interference with the smart key.
If this occurs, your vehicle may not
start. Remove any metal objects or
additional keys near the smart key before
attempting to start the vehicle again.
If the system repeatedly does not
recognize the coding of the key, it is
recommended that you contact your
HYUNDAI dealer.
Do not attempt to alter this system
or add other devices to it. Electrical
problems could result that may make
your vehicle inoperable.

STEERING WHEEL
Electric Power Steering (EPS)
The system assists you with steering the
vehicle. If the vehicle is turned off or
if the power steering system becomes
inoperative, you may still steer the
vehicle, but it will require increased
steering effort.
Also, the steering effort 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 system
checked by an authorized HYUNDAI
dealer.
CAUTION
• If the Electric Power Steering System
does not operate normally, the
warning light (
) will illuminate
on the instrument cluster. You may
steer the vehicle, but it will require
increased steering efforts. Take your
vehicle to an authorized HYUNDAI
dealer and have the system checked
as soon as possible.
• When an abnormality is detected
in the electric power steering
system, to prevent a an accident, the
steering assist function may become
inoperative. 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 immediately,
after moving the vehicle to a safe
area.
Information
The following symptoms may occur during
normal vehicle operation:
• The steering effort may be high
immediately after placing the ignition
switch in the ON position.
This happens as the system performs
the EPS system diagnostics. When the
diagnostics are completed, the steering
wheel effort will return to its normal
condition.
• When the battery voltage is low, you
might have to put more steering effort.
However, it is a temporary condition so
that it will return to normal condition
after charging the battery.
• A click noise may be heard from the
EPS relay after the ignition switch is in
the ON or LOCK/OFF position.
• Motor noise may be heard when the
vehicle is at a stop or at a low driving
speed.
• When you operate the steering wheel
in low temperatures, abnormal noise
may occur. If the temperature rises, the
noise will disappear. This is a normal
condition.
• When an error is detected from the
EPS, the steering effort assist function
may become inoperative in order to
prevent fatal accidents. Instrument
cluster warning lights may be on or the
steering effort may be high. If these
symptoms occur, drive the vehicle to
a safe area as soon as it is safe to do
so. Have the system checked by an
authorized HYUNDAI dealer as soon
as possible.
