Driving your vehicle
More severe weather conditions of winter
result in greater wear and other prob-
lems. To minimize winter driving problem,
you should follow these suggestions:
Snowy or icy conditionsTo 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 on the tire will
provide a greater driving force, but will
not prevent side skids.✽NOTICETire chains are not legal in all states.
Check state laws before fitting tire
chains.
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.

5Tire 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
0.47 in (12 mm). Damage to your vehicle
caused by improper snow chain use is
not covered by your vehicle manufactur-
ers warranty.
When using tire chains, install them on
the front tires only. 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 yourtires. 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 bedamaged from contacting vehicle components causing the snowchains to come loose from thetire. Make sure the snow chainsare SAE 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 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.

Driving your vehicle
Use high quality ethylene glycol
coolantYour 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.Check battery and cablesWinter 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.
Change to "winter weight" oil if
necessaryIn 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.Check spark plugs and ignition
systemInspect 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 adverselyaffect 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.

5To keep locks from freezingTo keep the locks from freezing, squirt an
approved de-icer fluid or glycerine into
the key opening. If a lock is covered with
ice, squirt it with an approved de-icing
fluid to remove the ice. If the lock is
frozen internally, you may be able to thaw
it out by using a heated key. Handle the
heated key with care to avoid injury.Use approved window washer
anti-freeze in systemTo keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the con-
tainer. Window washer anti-freeze is
available from an authorized HYUNDAI
dealer and most auto parts outlets. Do
not use engine coolant or other types of
anti-freeze as these may damage the
paint finish.
Don't let your parking brake
freezeUnder some conditions your parking
brake can freeze in the engaged position.
This is most likely to happen when there
is an accumulation of snow or ice around
or near the rear brakes or if the brakes
are wet. If there is a risk the parking
brake may freeze, apply it only temporar-
ily while you put the shift lever in P (auto-
matic transaxle) or in first or reverse gear
(manual transaxle) and block the rear
wheels so the vehicle cannot roll. Then
release the parking brake.Don't let ice and snow accumu-
late underneathUnder some conditions, snow and ice
can build up under the fenders and inter-
fere with the steering. When driving in
severe winter conditions where this may
happen, you should periodically check
underneath the car to be sure the move-
ment of the front wheels and the steering
components is not obstructed.
Carry emergency equipmentDepending on the severity of the weath-
er where you drive your car, you should
carry appropriate emergency equipment.
Some of the items you may want to carry
include tire chains, tow straps or chains,
flashlight, emergency flares, sand, a
shovel, jumper cables, a window scraper,
gloves, ground cloth, coveralls, a blanket,
etc.

7Tire 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.1. Manufacturer or brand nameManufacturer or Brand name is
shown.
2. Tire size designation A tire’s sidewall is marked with a tire
size designation. You will need this
information when selecting replace-
ment tires for your car. The following
explains what the letters and num-
bers in the tire size designation
mean.
Example tire size designation:
(These numbers are provided as an
example only; your tire size designa-
tor could vary depending on your
vehicle.)
P205/65R16 94H
P - Applicable vehicle type (tires
marked with the prefix “P’’ are
intended for use on passenger
cars or light trucks; however, not
all tires have this marking).
205 - Tire width in millimeters.
65 - Aspect ratio. The tire’s section height as a percentage of its
width.
R - Tire construction code (Radial).
16 - Rim diameter in inches. 94 - Load Index, a numerical code
associated with the maximum
load the tire can carry.
H - Speed Rating Symbol. See the speed rating chart in this section
for additional information.
Wheel size designation Wheels are also marked with impor-
tant information that you need if you
ever have to replace one. The follow-
ing explains what the letters and
numbers in the wheel size designa-
tion mean.
Example wheel size designation:
6.5JX16
6.5 - Rim width in inches.

7Do not drive faster than 75 mph (120
km/h) when your car is equipped with
snow tires.
Tire chains
Tire chains, if necessary, should be
installed on the front wheels.
Be sure that the chains are installed
in accordance with the manufactur-
er's instructions.
To minimize tire and chain wear, do
not continue to use tire chains when
they are no longer needed.
Radial-ply tiresRadial-ply tires provide improved
tread life, road hazard resistance and
smoother high speed ride. The radi-
al-ply tires used on this vehicle are of
belted construction, and are selected
to complement the ride and handling
characteristics of your vehicle.
Radial-ply tires have the same load
carrying capacity, as bias-ply or bias
belted tires of the same size, and use
the same recommended inflation
pressure. Mixing of radial-ply tires
with bias-ply or bias belted tires is
not recommended. Any combina-
tions of radial-ply and bias-ply or bias
belted tires when used on the same
vehicle will seriously deteriorate
vehicle handling. The best rule to fol-
low is: Identical radial-ply tires should
always be used as a set of four.
Longer wearing tires can be more
susceptible to irregular tread wear. It
is very important to follow the tire
rotation interval shown in this section
to achieve the tread life potential of
these tires. Cuts and punctures in
radial-ply tires are repairable only in
the tread area, because of sidewall
flexing. Consult your tire dealer for
radial-ply tire repairs.
WARNING
- Snow or ice
• When driving on roads cov- ered with snow or ice, drive at
less than 20 mph (30 km/h).
• Use the SAE “S” class or wire chains.
• If you hear noise caused by chains contacting the body,
retighten the chain to avoid
contact with the vehicle body.
• To prevent body damage, retighten the chains after driv-
ing 0.3~0.6 miles (0.5~1.0 km).
• Do not use tire chains on vehicles equipped with alu-
minum wheels. In unavoid-
able circumstance, use a wire
type chain.
• Use wire chains less than 0.47 inches (12 mm) to prevent
damage to the chain’s con-
nection.
