ESP indicator (Electronic
Stability Program)
The ESP indicator will illuminate when
the ignition switch is turned ON, but
should go off after approximately 3 sec-
onds. When the ESP is on, it monitors the
driving conditions and under normal driv-
ing conditions, the ESP indicator will
remain off. When a slippery or low trac-tion condition is encountered, the ESP
will operate, and the ESP indicator will
blink to indicate the ESP is operating.
If ESP indicator illuminates the ESP
may have a malfunction. We recommend
that the system be checked by an author-
ized HYUNDAI dealer.
ESP OFF indicator
The ESP OFF indicator will illuminate
when the ignition switch is turned ON,
but should go off after approximately 3
seconds. To switch to ESP OFF mode,
press the ESP OFF button . The ESP
OFF indicator will illumi-
nate indicating the ESP is deactivated.
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.
CAUTION
Do not use the parking brake to
stop the vehicle except in an emer- gency situation.
CAUTION
Driving with varying tire or wheelsizes 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.

Driving your vehicle
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 firstchecking local, state and municipal regu-lations for possible restrictions againsttheir use.
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.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.
CAUTION
Make sure the snow chains are the correct size and type for your
tires. Incorrect snow chains can cause damage to the vehicle bodyand suspension and may not becovered by your vehicle manufac-
turer warranty. Also, the snowchain connecting hooks may be damaged 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 to 0.6 miles) to ensure safe mount-ing. Retighten or remount the
chains if they are loose.

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. 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.
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the bat-
tery and cables as described in section
7. We recommend that the level of
charge in your battery be checked by an
authorized HYUNDAI dealer.
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.
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.

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 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.

Maintenance
TIRES AND WHEELS
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. 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 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 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.
OBK082005L
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,we recommend that the sys-tem be 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.

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.
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.

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 mountedon the same compact spare tire
wheel. The compact spare tire is notdesigned to be mounted on a regular
size wheel, and the compact spare
tire wheel is not designed for mount-
ing a regular size tire. 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 widthand 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 ESP
(Electronic Stability Program)
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
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. 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 thewheel 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 removedfrom the wheel.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. TheTIN can be used to identify the tire incase of a recall.
1. Manufacturer or brand name
