The ESC OFF indicator light comes
on when the ESC is turned off with
the button. Driving with wheels and tires with
different sizes may cause the ESC
system to malfunction. Before
replacing tires, make sure all fourtires and wheels are the same
size. Never drive the vehicle with
different sized tires and wheelsinstalled.ESC OFF usage
When Driving
The ESC OFF mode should only be
used briefly to help free the vehicle if
stuck in snow or mud by temporarily
stopping operation of the ESC to
maintain wheel torque.
To turn ESC off while driving, press
the ESC OFF button while driving on
a flat road surface.To prevent damage to the trans-mission:
Do not allow wheel(s) of one
axle to spin excessively while
the ESC, ABS, and parking brake
warning ( , red color) lights
are displayed. The repairs would
not be covered by the vehicle
warranty. Reduce engine powerand do not spin the wheel(s)
excessively while these lights
are displayed.
When operating the vehicle on a dynamometer, make sure theESC is turned off (ESC OFF lightilluminated).
Information
Turning the ESC off does not affect
ABS or standard brake system opera-
tion.

The Lane Keeping Assist System
helps detect the lane markers on the
road with a camera at the front wind-
shield, and assists the driver's steer-
ing to help keep the vehicle in the
lanes.
When the system detects the vehicle
straying from its lane, it alerts the
driver with a visual and audible warn-ing, while applying a slight counter-
steering torque, trying to prevent the
vehicle from moving out of its lane.

Driver is responsible for being
aware of surroundings and
steering the vehicle for safedriving practices.
Do not steer the steering
wheel suddenly when thesteering wheel is being assist-
ed by the system.
LKAS helps prevent the driver
from moving out of the lane
unintentionally by assisting
the driver's steering. However,
the system is just a conven-ience function and the steer-
ing wheel is not always con-
trolled. While driving, the driv-
er should pay attention to thesteering wheel.
The operation of the LKAS
can be cancelled or not work
properly according to road
condition and surroundings.
Always be cautious whendriving.
WARNING
Do not disassemble LKAS
camera temporarily for tinted
window or attaching anytypes of coatings and acces-
sories. If you disassemble a
camera and assemble it again,
take your vehicle to an author-
ized HYUNDAI dealer and
have the system checked for acalibration.
When you replace the wind-
shield glass, LKAS camera or
related parts of the steering,
take your vehicle to an author-
ized HYUNDAI dealer and
have the system checked for acalibration.
The system detects lane
markers and controls the
steering wheel by a camera,
therefore, if the lane markers
are hard to detect, the system
may not work properly.
Always be cautious whenusing the system.

LKAS operation
To activate/deactivate the LKAS:
With the ignition switch in the ON
position, press the LKAS button
located on the instrument panel on
the lower left hand side of the driver.
The indicator in the cluster display
will initially illuminate white.
When the indicator(white) activated
in the previous ignition cycle, the
system turns on without any control.
Do not place objects on the
dashboard that reflects light
such as mirrors, white paper,
etc. The system may malfunc-tion if the sunlight is reflected.
Do not place any accessories
near the rearview mirror.
You may not hear warning sound of LKAS because of the
excessive audio sound.(Continued)
(Continued)
If you continue to drive with
your hands off the steering
wheel, the LKAS will stop con-
trolling the steering wheelafter the hands off alarm.
After then, if you drive with
your hands on the steering
wheel, the control will be acti-
vated again.
If the vehicle speed is high,
steering torque for assistancewill not be enough to keep
your vehicle within the lane. If
so, the vehicle may move out
of its lane.
If you attach objects to the
steering wheel, the system
may not assist steering.
If you attach objects to the
steering wheel, hands off
alarm may not work properly.
WARNING
(Continued)
When the lane markers are
hard to detect, please refer to"Limitation of the System".
Do not remove or damage the
related parts of LKAS.

If the vehicle moves out its lane
because steering torque for assis-tance is not enough, the line indica-
tor of deviation direction will blink.Keep hands on steering wheel
If the driver takes hands off the steer-
ing wheel for several seconds while
the LKAS is activated, the system
will warn the driver.5

The warning message may
appear late according to road
conditions. Therefore, always
have your hands on the steer-ing wheel while driving.
If you hold the steering wheel
lightly, the system would gen-erate hands off warningbecause LKAS can treat the
situation as you do not grabthe wheel.

Maintenance
Brake discs, pads, calipers
and rotors
Check the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.
For more information on checking
the pads or lining wear limit, refer to
the HYUNDAI web site. (http://ser
vice.hyundai-motor.com)
Exhaust pipe and muffler
Visually inspect the exhaust pipes,
muffler and hangers for cracks, dete-
rioration, or damage. Start the
engine and listen carefully for any
exhaust gas leakage. Tighten con-
nections or replace parts as neces-
sary.
Suspension mounting bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and the
hybrid system off, check for exces-
sive free-play in the steering wheel.
Check the linkage for bends or dam-
age. Check the dust boots and ball
joints for deterioration, cracks, or
damage.
Replace any damaged parts.
Drive shafts and boots
Check the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged
parts and, if necessary, repack the
grease.
Air conditioning refrigerant
Check the air conditioning lines and
connections for leakage and damage.

Maintenance
Tire rotation
To equalize tread wear, HYUNDAI recommends that the tires be rotated
every 12,000 km (7,500 miles) or
sooner if irregular wear develops.
During rotation, check the tires for
correct balance.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pres-
sure, improper wheel alignment, out-
of-balance wheels, severe braking or
severe cornering. Look for bumps or
bulges in the tread or side of tire.
Replace the tire if you find either of
these conditions. Replace the tire if
fabric or cord is visible. After rotation,
be sure to bring the front and rear tire
pressures to specification and check
lug nut tightness (proper torque is11-13 kgf
m [79-94 lbf ft]). Disc brake pads should be inspected
for wear whenever tires are rotated. Information
The outside and inside of the unsym-
metrical tire is distinguishable. When
installing an unsymmetrical tire, be
sure to install the side marked "out-
side" face the outside. If the side
marked "inside" is installed on the
outside, it will have a bad effect on
vehicle performance.

■ Without a spare tire
Do not use the compact spare
tire for tire rotation.
Do not mix bias ply and radial
ply tires under any circum-
stances. This may cause
unusual handling characteris-
tics that may cause loss of
vehicle control resulting in anaccident.
