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 lights are displayed.
The repairs would not be cov-
ered by the vehicle warranty.
Reduce engine power and do
not spin the wheel(s) excessive-
ly while these lights are dis-
played.
When operating the vehicle on a dynamometer, make sure the
ESC is turned off (ESC OFF light
illuminated).
Information
Turning the ESC off does not affect
ABS or standard brake system opera-
tion.
Vehicle Stability Management
(VSM)
The Vehicle Stability Management
(VSM) is a function of the Electronic
Stability Control (ESC) system. It
helps ensure the vehicle stays stable
when accelerating or braking sud-
denly on wet, slippery and rough
roads where traction over the four
tires can suddenly become uneven.
i
NOTICE
Take the following precautions
when using the Vehicle Stability
Management (VSM):
ALWAYS check the speed and
the distance to the vehicle
ahead. The VSM is not a sub-
stitute for safe driving prac-
tices.
Never drive too fast for the
road conditions. The VSM sys-
tem will not prevent acci-
dents. Excessive speed in bad
weather, slippery and uneven
roads can result in severe
accidents.
WARNING

Driving your vehicle
The Lane Keeping Assist System
helps detect 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 between
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, to try to prevent the
vehicle from moving out of its lane.

The lane keeping assist system
is not a substitute for safe driv-
ing practices, but a conven-
ience function only. It is the
responsibility of the driver to
always be aware of the sur-
rounding and steer the vehicle.
WARNING
Take the following precautions
when using the Lane Keeping
Assist System (LKAS):
Do not steer the steering
wheel suddenly when the
steering wheel is being assist-
ed by the system.
LKAS helps to prevent the driv-
er from moving out of the lane
unintentionally by assisting the
driver's steering. However, the
driver should not solely rely on
the system but always pay
attention on the steering wheel
to stay in the lane.
(Continued)
WARNING
(Continued)
The operation of the LKAS
can be canceled or not work
properly according to road
condition and surroundings.
Always be cautious when
driving.
Do not disassemble the LKAS
camera temporarily to tint the
window or attach any types of
coatings and accessories. If
you disassemble the camera
and assemble it again, take
your vehicle to an authorized
HYUNDAI dealer and have the
system checked for calibra-
tion.
When you replace the wind-
shield glass, LKAS camera or
related parts of the steering
wheel, take your vehicle to an
authorized HYUNDAI dealer
and have the system checked
for calibration.(Continued)

What to do in an emergency
6
9. Loosen the lug nuts with the wheellug nut wrench and remove them
with your fingers. Remove the
wheel from the studs and lay it flat
on the ground out of the way.
Remove any dirt or debris from
the studs, mounting surfaces, and
wheel.
10. Install the spare tire onto the studs of the hub.
11. Tighten the lug nuts with your fin- gers onto the studs with the
smaller end of the lug nuts clos-
est to the wheel.
12. Lower the vehicle to the ground by turning the jack handle coun-
terclockwise.
13. Use the wheel lug nut wrench to tighten the lug nuts in the order
shown. Double-check each lug
nut until they are tight. After
changing tires, have an author-
ized HYUNDAI dealer tighten the
lug nuts to their proper torque as
soon as possible. The wheel lug
nut should be tightened to
79~94 lbf·ft (11~13 kgf·m). If you have a tire gage, check the tire
pressure (see "Tires and Wheels" in
chapter 8 for tire pressure instruc-
tions.). If the pressure is lower or
higher than recommended, drive
slowly to the nearest service station
and adjust it to the recommended
pressure. Always reinstall the valve
cap after checking or adjusting tire
pressure. If the cap is not replaced,
air may leak from the tire. If you lose
a valve cap, buy another and install it
as soon as possible. After changing
tires, secure the flat tire and return
the jack and tools to their proper stor-
age locations. Check the tire pressure as soon
as possible after installing a
spare tire. Adjust it to the rec-
ommended pressure.
Check and tighten the wheel lug nuts after driving over 30 mph
(50 km) if tires are replaced.
Recheck the tire wheel lug nuts
after driving over 620 mph (1,000
km).NOTICE

What to do in an emergency
If any of the equipment such as the
jack, lug nuts, studs, or other equip-
ment is damaged or in poor condi-
tion, do not attempt to change the
tire and call for assistance.
Use of compact spare tires
Compact spare tires are designed for
emergency use only. Drive carefully
on the compact spare tire and
always follow the safety precautions. When driving with the compact spare
tire mounted to your vehicle:
Check the tire pressure after
installing the compact spare tire.
The compact spare tire should be
inflated to 60 psi (420 kPa).
Do not take this vehicle through an automatic car wash while the com-
pact spare tire is installed.
Do not use the compact spare tire on any other vehicle because this
tire has been designed especially
for your vehicle.
The compact spare tire’s tread life is shorter than a regular tire.
Inspect your compact spare tire
regularly and replace worn com-
pact spare tires with the same size
and design, mounted on the same
wheel.
Do not use more than one compact spare tire at a time.
When the original tire and wheel
are repaired and reinstalled on the
vehicle, the lug nut torque must be
set correctly. The correct lug nut
tightening torque is 79~94 lbf·ft
(11~13 kgf·m).
NOTICE
Your vehicle has metric threads
on the studs and lug nuts. Make
certain during tire changing that
the same nuts that were
removed are reinstalled. If you
have to replace your lug nuts
make sure they have metric
threads to avoid damaging the
studs and ensure the wheel is
properly secured to the hub.
Consult an authorized HYUNDAI
dealer for assistance.
CAUTION
To prevent compact spare tire
failure and loss of control pos-
sibly resulting in an accident:
Use the compact spare tire
only in an emergency.
NEVER operate your vehicle
over 50 mph (80 km/h).
Do not exceed the vehicle's
maximum load rating or the
load carrying capacity shown
on the sidewall of the com-
pact spare tire.
Do not use the compact spare
tire continuously. Repair or
replace the original tire as
soon as possible to avoid fail-
ure of the compact spare tire.

Maintenance
Brake Hoses and Lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
Brake/Clutch Fluid
Check the brake/clutch fluid level in
the brake/clutch fluid reservoir. The
level should be between the MIN and
the MAX marks on the side of the
reservoir. Use only hydraulic
brake/clutch fluid conforming to DOT
3 or DOT 4 specification.
Parking Brake
Inspect the parking brake system
including the parking brake pedal
and cables.
Brake Discs, Pads, Calipers
and Rotors
Check the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.
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 connections or
replace parts as necessary.
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
engine off, check for excessive free-
play in the steering wheel. Check the
linkage for bends or damage. 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 dam-
age.

Maintenance
Check Tire Inflation Pressure
Check your tires, including the spare
tire, once a month or more.
How to check
Use a good quality tire pressure
gauge to check tire pressure. You
can not tell if your tires are properly
inflated simply by looking at them.
Radial tires may look properly inflat-
ed when they are under-inflated.
Remove the valve cap from the tire
valve stem. Press the tire gauge firm-
ly onto the valve to get a pressure
measurement. If the cold tire inflation
pressure matches the recommended
pressure on the tire label located on
the driver's side center pillar or in this
manual. No further adjustment is
necessary. If the pressure is low, add
air until you reach the recommended
pressure. Make sure to put the valve
caps back on the valve stems.
Without the valve cap, dirt or mois-
ture could get into the valve core and
cause air leakage. If a valve cap is
missing, install a new one as soon as
possible.If you overfill the tire, release air by
pushing on the metal stem in the
center of the tire valve. Recheck the
tire pressure with the tire gauge. Be
sure to put the valve caps back on
the valve stems. Without the valve
cap, dirt or moisture could get into
the valve core and cause air leakage.
If a valve cap is missing, install a new
one as soon as possible.
A cold tire means the vehicle has
been sitting for 3 hours and driven for
less than 1 mile (1.6 km) in that 3
hour period.
Allow the tire to cool before measur-
ing the inflation pressure. Always be
sure the tire is cold before inflating to
the recommended pressure.
Tire Rotation
To equalize tread wear, HYUNDAI
recommends that the tires be rotated
according to the maintenance sched-
ule or sooner if irregular wear devel-
ops.
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 the tire.
Replace the tire if you find any 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 is
79~94 lbf·ft [11~13 kgf·m]).

It is permissible to add 3 psi to the standard tire pressure specification if colder temperatures are expect- ed soon.
Tires typically loose 1psi (7kPa) for every 12°F temperature drop. If extreme temperature variations are
expected, recheck your tire pressure as necessary to keep them properly inflated.
An air pressure generally decreases, as you drive up to a high-altitude area above sea level. Thus, if you plan to drive a high-altitude area, check the tire pressures in advance. If necessary, inflate them to a prop-
er level. (Air inflation per altitude : +2.4 psi/1 mile)
Tires get higher strain when driving at high speed than under normal condition,\
and can cause tire failure. Therefore, if you are driving at sustained high speed (over 100 mile/h or 160 km/h) with 225/40R18 sized
tires, add 5 psi to the standard tire pressure. However, do not exceed the maximum inflation pressure indi-
cated on the tire sidewall.
