but should go off after approximately 3
seconds. To switch to ESP OFF mode,
press the ESP OFF button . The ESP
OFF indicator will illuminate indicating
the ESP is deactivated.
If this indicator stays on when ESP OFF
is not selected, the ESP may have a mal-
function. Take your car to an authorized
HYUNDAI dealer and have the system
checked.
If you use the parking brake to stop the
vehicle with the ESP system in the stand-
by position when the brake is not work
normally, the ESP system may be stop
operation and ESP OFF indicator may be
illuminated for about 5 minutes.E070504ABH-EE
ESP OFF usage
When driving
ESP should be turned on for daily driv-
ing whenever possible. If ESP is turned
off, it is difficult to make a turn or driveup a hill.
To turn ESP off while driving, press the ESP OFF button while driving on a
flat road surface.
Never press the ESP OFF button
while ESP is operating (ESP indicator
light blinks).
If ESP is turned off while ESP is operat-
ing, it may be very dangerous because of
unexpected vehicle slip.
✽✽ NOTICE
 When operating the vehicle on a dynamometer, ensure that the ESP is
turned off (ESP OFF light illumi-
nated). If the ESP is left on, it may
prevent the vehicle speed from
increasing, and result in false diagno-
sis.
 Turning the ESP off does not affect ABS or brake system operation.
CAUTION
Driving with varying tire or wheel
sizes may cause the ESP system to
malfunction. When replacing tires,make sure they are the same size asyour original tires.
WARNING
The Electronic Stability Program
system is only a driving aid; use
precautions for safe driving by
slowing down on curved, snowy, or
icy roads. Drive slowly and don’t
attempt to accelerate whenever the
ESP indicator light is blinking, or
when the road surface is slippery.
CAUTION
Do not use the parking brake to stop the vehicle except in an emer-gency situation.

More severe weather conditions of winter
result in greater wear and other prob-
lems. To minimize winter driving problem,
you should follow these suggestions: E120100ABK
Snowy or icy conditions
To drive your vehicle in deep snow, it may
be necessary to use snow tires or to
install tire chains on your tires. If snow
tires are needed, it is necessary to select
tires equivalent in size and type of the
original equipment tires. Failure to do so
may adversely affect the safety and han-
dling of your car. Furthermore, speeding,
rapid acceleration, sudden brake appli-
cations, and sharp turns are potentially
very hazardous practices. During deceleration, use engine braking
to the fullest extent. Sudden brake appli-
cations on snowy or icy roads may cause
skids to occur. You need to keep suffi-
cient distance between the vehicle in
operation in front and your vehicle. Also,
apply the brake gently. It should be notedthat installing tire chains on the tire will
provide a greater driving force, but will
not prevent side skids.
✽✽
NOTICE
Tire chains are not legal in all countries.
Check the country laws before fitting
tire chains.
E120101AUN
Snow tires
If you mount snow tires on your vehicle,
make sure they are radial tires of the
same size and load range as the original
tires. Mount snow tires on all four wheels
to balance your vehicle’s handling in all
weather conditions. Keep in mind that the
traction provided by snow tires on dry
roads may not be as high as your vehi-
cle's original equipment tires. You should
drive cautiously even when the roads are
clear. Check with the tire dealer for max-
imum speed recommendations.
Do not install studded tires without first checking local, state and municipal regu-
lations for possible restrictions againsttheir use.
WINTER DRIVING
WARNING - Snow tire size
Snow tires should be equivalent in
size and type to the vehicle's stan-
dard tires. Otherwise, the safety
and handling of your vehicle may
be adversely affected.
OBK059025
CAUTION
If your vehicle is equipped with the summer tire for the best driving
performance on the dry street, its performance is low, so when driv-ing on the rain and wet roads,replace the tires by snow tires or all
season tires.

Tire chains
Since the sidewalls of radial tires are
thinner, they can be damaged by mount-
ing some types of snow chains on them.
Therefore, the use of snow tires is rec-
ommended instead of snow chains. Do
not mount tire chains on vehicles
equipped with aluminum wheels; snow
chains may cause damage to the wheels.
If snow chains must be used, use wire-
type chains with a thickness of less than
12 mm (0.47 in). Damage to your vehicle
caused by improper snow chain use is
not covered by your vehicle manufactur-
ers warranty.
Install tire chains only on the rear tires.Chain installation
When installing chains, follow the manu-
facturer's instructions and mount them as
tightly as you can. Drive slowly with
chains installed. If you hear the chains
contacting the body or chassis, stop and
tighten them. If they still make contact,
slow down until it stops. Remove the
chains as soon as you begin driving on
cleared roads.
CAUTION
Make sure the snow chains are
the correct size and type for your
tires. Incorrect snow chains cancause damage to the vehicle bodyand suspension and may not be covered by your vehicle manufac-
turer warranty. Also, the snowchain connecting hooks may bedamaged from contacting vehicle
components causing the snow chains to come loose from thetire. Make sure the snow chainsare SAE class “S” certified.
Always check chain installation for proper mounting after drivingapproximately 0.5 to 1 km (0.3 to0.6 miles) to ensure safe mount-ing. Retighten or remount the
chains if they are loose.
WARNING
- Mounting chains
When mounting snow chains, park
the vehicle on level ground away
from traffic. Turn on the vehicle
Hazard Warning flashers and place
a triangular emergency warning
device behind the vehicle if avail-
able. Always place the vehicle in P
(Park), apply the parking brake and
turn off the engine before installing
snow chains.1JBA4068

Use high quality ethylene glycol coolant
Your vehicle is delivered with high quality
ethylene glycol coolant in the cooling
system. It is the only type of coolant that
should be used because it helps prevent
corrosion in the cooling system, lubri-
cates the water pump and prevents
freezing. Be sure to replace or replenish
your coolant in accordance with themaintenance schedule in section 7.
Before winter, have your coolant tested toassure that its freezing point is sufficient
for the temperatures anticipated during
the winter. E120300AEN
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the bat-
tery and cables as described in section
7. The level of charge in your battery can
be checked by an authorized HYUNDAI
dealer or a service station. E120400ABH
Change to "winter weight" oil if
necessary In some climates it is recommended that
a lower viscosity "winter weight" oil be
used during cold weather. See section 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorized HYUNDAI dealer.
E120500AUN
Check spark plugs and ignition system
Inspect your spark plugs as described in
section 7 and replace them if necessary.
Also check all ignition wiring and compo-
nents to be sure they are not cracked,
worn or damaged in any way.
WARNING
- Tire chains
The use of chains may adversely affect vehicle handling.
Do not exceed 30 km/h (20 mph) or the chain manufacturer’s rec-
ommended speed limit, whichev-
er is lower.
Drive carefully and avoid bumps, holes, sharp turns, and other
road hazards, which may cause
the vehicle to bounce.
Avoid sharp turns or locked- wheel braking.
CAUTION
Chains that are the wrong size or
improperly installed can damage
your vehicle's brake lines, sus-pension, body and wheels.
Stop driving and retighten the chains any time you hear themhitting the vehicle.

Important - use of compact spare tire(if equipped)
Your vehicle is equipped with a com-
pact spare tire. This compact spare
tire takes up less space than a regu-
lar-size tire. This tire is smaller than a
conventional tire and is designed for
temporary use only.
The compact spare should be inflat-
ed to 420 kPa (60 psi).
✽✽NOTICE
Check the inflation pressure after
installing the spare tire. Adjust it to
the specified pressure, as necessary.
When using a compact spare tire,
observe the following precautions:
Under no circumstances should you exceed 80 km/h (50 mph); a higher speed could damage the
tire.
Ensure that you drive slowly enough for the road conditions to
avoid all hazards. Any road hazard,
such as a pothole or debris, could
seriously damage the compact
spare.
Any continuous road use of this tire could result in tire failure, loss of
vehicle control, and possible per-
sonal injury.
Do not exceed the vehicle’s maxi- mum load rating or the load-carry-
ing capacity shown on the sidewall
of the compact spare tire.
Avoid driving over obstacles. The compact spare tire diameter issmaller than the diameter of a con-
ventional tire and reduces the
ground clearance approximately25 mm (1 inch), which could result
in damage to the vehicle.
CAUTION
You should drive carefully
when the compact spare tireis in use. The compact sparetire should be replaced by theproper conventional tire and rim at the first opportunity.
The operation of this vehicle is not recommended withmore than one compact sparetire in use at the same time.
WARNING
The compact spare tire is for
emergency use only. Do not
operate your vehicle on this
compact spare at speeds over
80 km/h (50 mph). The originaltire should be repaired or
replaced as soon as possible to
avoid failure of the spare possi-
bly leading to personal injury ordeath.

What to do in an emergency

Do not take this vehicle through an
automatic car wash while the com- pact spare tire is installed.
Do not use tire chains on the com- pact spare tire. Because of the
smaller size, a tire chain will not fit
properly. This could damage the
vehicle and result in loss of thechain.
Do not use the compact spare tire on any other vehicle because thistire 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 sizeand design, mounted on the samewheel. The compact spare tire should not
be used on any other wheels, nor
should standard tires, snow tires,
wheel covers or trim rings be used
with the compact spare wheel. Ifsuch use is attempted, damage tothese items or other car compo-
nents may occur.
Do not use more than one compact spare tire at a time.
Do not tow a trailer while the com- pact spare tire is installed.

CAUTION
Underinflation also results in
excessive wear, poor handlingand reduced fuel economy. Wheel deformation also ispossible. Keep your tire pres-sures at the proper levels. If a tire frequently needs refilling,have it checked by an author-ized HYUNDAI dealer.
Overinflation produces a harsh ride, excessive wear atthe center of the tire tread, anda greater possibility of dam-age from road hazards.
TIRES AND WHEELS
G200100AUN Tire care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle. G200200AEN Recommended cold tire inflation pressures All tire pressures (including the
spare) should be checked when the
tires are cold. “Cold Tires” means the
vehicle has not been driven for at
least three hours or driven less than1.6 km (one mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.
For recommended inflation pressure,
refer to “Tire and wheels” in section8. All specifications (sizes and pres-
sures) can be found on a label
attached to the vehicle.
WARNING - Tire underin-
flation
Severe underinflation can lead
to severe heat build-up, causing
blowouts, tread separation andother tire failures that can result
in the loss of vehicle control
leading to severe injury or
death. This risk is much higher
on hot days and when driving
for long periods at high speeds.

Maintenance
Disc brake pads should be inspectedfor wear whenever tires are rotated.
✽✽ NOTICE
The front tire size is different from
the rear tire size. So when you rotate
tires, check the tire and wheel size.
G200500AUN Wheel alignment and tire balance
The wheels on your vehicle were aligned and balanced carefully at the
factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may needto be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.
OBK079038
Without a spare tire
WARNING
Do not mix bias ply and radial
ply tires under any circum-
stances. This may cause unusu-
al handling characteristics that
could result in death, severe
injury, or property damage.
CAUTION
Improper wheel weights can damage your vehicle's alu-minum wheels. Use onlyapproved wheel weights.
