ESC OFF usage
When driving
ESC should be turned on for daily driv-
ing whenever possible. If ESC is turned
off, it may be difficult to make a turn or
drive up a hill.
To turn ESC off while driving, press the ESC OFF button while driving on a
flat road surface.
Never press the ESC OFF button
while ESC is operating (ESC indicator
light blinks).
If ESC is turned off while ESC is operat-
ing, it may be very dangerous because of
unexpected vehicle slip.
✽ ✽ NOTICE
• When operating the vehicle on a
dynamometer, ensure that the ESC is
turned off (ESC OFF light illumi-
nated). If the ESC is left on, it may
prevent the vehicle speed from
increasing, and result in false diagno-
sis.
• Turning the ESC off does not affect ABS or brake system operation.
CAUTION
Driving with varying tire or wheel
sizes may cause the ESC system tomalfunction. When replacing tires,make sure they are the same size asyour original tires.
WARNING
The Electronic Stability Control sys-
tem is only a driving aid; use pre-
cautions for safe driving by slowing
down on curved, snowy, or icy
roads. Drive slowly and don’t
attempt to accelerate whenever the
ESC 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 prob-
lems, you should follow these sugges-
tions:
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 noted
that installing tire chains 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.

Tire chains
Since the sidewalls of radial tires are
thinner, they can be damaged by mount-
ing some types of tire chains on them.
Therefore, the use of snow tires is rec-
ommended instead of tire chains. Do not
mount tire chains on vehicles equipped
with aluminum wheels; tire chains may
cause damage to the wheels. If tire
chains must be used, use wire-type
chains with a thickness of less than 0.47
in (12 mm). Damage to your vehicle
caused by improper tire chain use is not
covered by your vehicle manufacturers
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 tire chains are the
correct size and type for yourtires. Incorrect tire chains cancause damage to the vehicle bodyand suspension and may not be covered by your vehicle manufac-turer warranty. Also, the tire chainconnecting hooks may be dam-aged from contacting vehiclecomponents causing the tirechains to come loose from thetire. Make sure the tire chains areSAE class “S” certified.
Always check chain installation for proper mounting after drivingapproximately 0.3 to 0.6 miles (0.5to 1 km) to ensure safe mounting.Retighten or remount the chainsif they are loose.
WARNING
- Mounting chains
When mounting tire 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
tire chains.

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 the
maintenance schedule in section 7.
Before winter, have your coolant tested to
assure 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 20 mph (30 km/h) 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 damageyour vehicle's brake lines, sus-pension, body and wheels.
Stop driving and retighten the chains any time you hear themhitting the vehicle.

What to do in an emergency
TIRE PRESSURE MONITORING SYSTEM (TPMS) (IF EQUIPPED)
(1) TPMS malfunction indicator
(2) Low tire pressure indicator
F060000BEN
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard or tire inflation pressure label. (If
your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation pres-
sure label, you should determine the
proper tire inflation pressure for
those tires.)As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your
tires is significantly under-inflated.
Accordingly, when the low tire pres-
sure indicator illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the
proper pressure. Driving on a signifi-
cantly under-inflated tire causes the
tire to overheat and can lead to tire
failure. Under-inflation also reduces
fuel efficiency and tire tread life, and
may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire mainte-
nance, and it is the driver’s responsi-
bility to maintain correct tire pres-
sure, even if under-inflation has not
reached the level to trigger illumina-
tion of the TPMS low tire pressure
indicator.
Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly. The TPMS mal-
function indicator is provided by a
separate indicator, which displays
the symbol "TPMS" when illuminat-
ed. When the malfunction indicator
is illuminated, the system may not be
able to detect or signal low tire pres-
sure as intended. TPMS malfunc-
tions may occur for a variety of rea-
sons, including the installation of
replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
indicator after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or alter-
nate tires and wheels allow the
TPMS to continue to function proper-
ly.

What to do in an emergency
Do not take this vehicle through anautomatic 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 the
chain.
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. 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. If
such use is attempted, damage to
these 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.

Maintenance
CAUTION
Underinflation also results inexcessive wear, poor handlingand reduced fuel economy.Wheel deformation also ispossible. Keep your tire pres-sures at the proper levels. If atire 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 than
one mile (1.6 km).
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 section
8. 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 and
other 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.

Disc brake pads should be inspected
for 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 need
to 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.

Compact spare tire replacement (if
equipped)
A compact spare tire has a shorter
tread life than a regular size tire.
Replace it when you can see the
tread wear indicator bars on the tire.
The replacement compact spare tire
should be the same size and design
tire as the one provided with your
new vehicle and should be mounted
on the same compact spare tire
wheel. The compact spare tire is not
designed to be mounted on a regular
size wheel, and the compact spare
tire wheel is not designed for mount-
ing a regular size tire.
G200700ABK
Wheel replacement
When replacing the metal wheels for
any reason, make sure the new
wheels are equivalent to the original
factory units in diameter, rim width
and offset.
✽ ✽ NOTICE
The front tire size is different from
the rear tire size. So when you rotate
tires, check the tire and wheel size.
(Continued)
Using tires and wheel other
than the recommended sizes
could cause unusual handling
characteristics and poor vehi-
cle control, resulting in a seri-
ous accident.
Wheels that do not meet HYUNDAI’s specifications
may fit poorly and result in
damage to the vehicle or
unusual handling and poor
vehicle control.
The ABS works by comparing the speed of the wheels. Tire
size can affect wheel speed.
When replacing tires, all 4
tires must use the size origi-
nally supplied with the vehi-
cle. Using tires of a different
size can cause the ABS (Anti-
lock Brake System) and ESC
(Electronic Stability Control)
to work irregularly.
WARNING
A wheel that is not the correct
size may adversely affect wheel
and bearing life, braking and
stopping abilities, handling
characteristics, ground clear-
ance, body-to-tire clearance,
snow chain clearance,
speedometer and odometer cal-
ibration, headlight aim and
bumper height.

Maintenance
G200800AUN
Tire traction
Tire traction can be reduced if you
drive on worn tires, tires that are
improperly inflated or on slippery
road surfaces. Tires should be
replaced when tread wear indicators
appear. To reduce the possibility of
losing control, slow down whenever
there is rain, snow or ice on the road.
G200900AUN
Tire maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease
tire wear. If you find a tire is worn
unevenly, have your dealer check the
wheel alignment.
When you have new tires installed,
make sure they are balanced. This
will increase vehicle ride comfort and
tire life. Additionally, a tire should
always be rebalanced if it is removed
from the wheel.G201000ABK
Tire sidewall labeling
This information identifies and
describes the fundamental charac-
teristics of the tire and also provides
the tire identification number (TIN)
for safety standard certification. The
TIN can be used to identify the tire in
case of a recall.
