Smooth cornering
Avoid braking or gear changing in
corners\b especially when roads are
wet. Ideally\b corners should always
be taken under gentle acceleration.
Driving at night
Night driving presents more hazards
than driving in the daylight. Here are
some important tips to remember:
• Slow down and keep more distance between you and other vehi
cles\b as it may be more difficult to
see at night\b especially in areas
where there may not be any street
lights.
• Adjust your mirrors to reduce the glare from other driver's head
lights.
• Keep your headlights clean and properly aimed. Dirty or improperly
aimed headlights will make it much
more difficult to see at night.
• Avoid staring directly at the head lights of oncoming vehicles. You
could be temporarily blinded\b and it
will take several seconds for your
eyes to readjust to the darkness.
Driving in the rain
Rain and wet roads can make driving
dangerous. Here are a few things to
consider when driving in the rain or
on slick pavement:
• Slow down and allow extra following distance. A heavy rainfall
makes it harder to see and increas
es the distance needed to stop
your vehicle.
• Replace your windshield wiper blades when they show signs of
streaking or missing areas on the
windshield.
• Be sure your tires have enough tread. If your tires do not have
enough tread\b making a quick stop
on wet pavement can cause a skid
and possibly lead to an accident.
See “Tire Tread ”
in chapter 7.
• Turn on your headlights to make it easier for others to see you.

To keep locks from freezing
To keep the locks from freezing\b
squirt an approved deicer fluid or
glycerine into the key opening. If a
lock is covered with ice\b squirt it with
an approved deicing fluid to remove
the ice. If the lock is frozen internally\b
you may be able to thaw it out by
using a heated key. Handle the heat
ed key with care to avoid injury.
Use approved window washerantifreeze in system
To keep the water in the window
washer system from freezing\b add an
approved window washer antifreeze
solution in accordance with instruc
tions on the container. Window wash
er antifreeze 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 freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to hap
pen 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\b apply it only temporarily
while you put the shift lever in P (for
Automatic Transaxle/Continuously
Variable Transaxle) or in first or
reverse gear (for Manual Transaxle)
and block the rear wheels so the
vehicle cannot roll. Then release the
parking brake.
Don't let ice and snow accumulate underneath
Under some conditions\b snow and
ice can build up under the fenders
and interfere with the steering. When
driving in severe winter conditions
where this may happen\b you should
periodically check underneath the
car to be sure the movement of the
front wheels and the steering com
ponents is not obstructed.
Carry emergency equipment
Depending on the severity of the
weather\b you should carry appropri
ate emergency equipment. Some of
the items you may want to carry
include tire chains\b tow straps or
chains\b flashlight\b emergency flares\b
sand\b shovel\b jumper cables\b window
scraper\b gloves\b ground cloth\b cover
alls\b blanket\b etc.
Don't place foreign objects or materials in the engine compartment
Placement of foreign objects or
materials which prevent cooling of
the engine\b in the engine compart
ment\b may cause a failure or com
bustion. The manufacturer is not
responsible for the damage caused
by such placement.

When driving with the compact spare
tire mounted to your vehicle:
• Check the tire pressure afterinstalling the compact spare tire.
The compact spare tire should be
inflated to 420 kPa (60 psi).
• 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.
• Do not tow a trailer while the com- pact spare tire is installed.
IInformation
When the original tire and wheel are
repaired and reinstalled on the vehi-
cle, the lug nut torque must be set cor-
rectly to prevent wheel vibration. The
correct lug nut tightening torque is
11~13 kgf.m (79~94 lbf.ft).
To prevent damaging the compact
spare tire and your vehicle:
• Drive slowly enough for the road condition s to avoid all hazards,
such as a potholes or debris.
• Avoid driving over obstacles. The compact spare t ire diameter is
smaller than the diameter of a con-
ventional tire and reduces the
ground clearance appr oximately
25 mm (1 inch).
• Do not use tire chains on the com- pact spare tire. Because of the
smaller siz e, a tire chain will not fit
properly.
• Do not use the compact spare tire on any other wheels, nor shoul d
standard tires, snow tires, wheel
covers or trim rings be used with
the compact spare wheel.NOTICE

1.(#,204/3424-322. 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.)P195/65R15 94HP - 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).
195 - Tire width in millimeters.
65 - Aspect ratio. The tire’s chapter height as a percentage of its
width.
R - Tire construction code (Radial).
15 - 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 chapter
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:6.0JX156.0 - Rim width in inches.
J - Rim contour designation.
15 - Rim diameter in inches.
Tire speed ratings The chart below lists many of the dif-
ferent speed ratings currently being
used for passenger car tires. The
speed rating is part of the tire size
designation on the sidewall of the
tire. This symbol corresponds to that
tire's designed maximum safe oper-
ating speed.
Speed
Rating
Symbol Maximum Speed
S 180 km/h (112 mph)
T 190 km/h (118 mph)
H 210 km/h (130 mph) V 240 km/h (149 mph)
W 270 km/h (168 mph) Y 300 km/h (186 mph)

1.(',204/3424-366. Maximum load ratingThis number indicates the maximum
load in kilograms and pounds that
can be carried by the tire. When
replacing the tires on the vehicle,
always use a tire that has the same
load rating as the factory installed
tire.7. Uniform tire quality grading Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and maxi-
mum chapter width.
For example:
TREAD wear 200
TRACTION AA
TEMPERATURE A
Tread wearThe tread wear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specified govern-
ment test course. For example, a tire
graded 150 would wear one-and-a-
half times (1½) as well on the gov-
ernment course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions
of their use, however, and may
depart significantly from the norm
due to variations in driving habits,
service practices and differences in
road characteristics and climate.
These grades are molded on the
side-walls of passenger vehicle tires.
The tires available as standard or
optional equipment on your vehicle
may vary with respect to grade.
Traction - AA, A, B & C The traction grades, from highest to
lowest, are AA, A, B and C. Those
grades represent the tire’s ability to
stop on wet pavement measured
under controlled conditions on spec-
ified government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction perform-
ance. The traction grade assigned to this
tire is based on straight-ahead
braking traction tests, and does
not include acceleration, corner-
ing, hydroplaning, or peak traction
characteristics.
WARNING

1.$#,204/3424-3!#Consult an authorized HYUNDAI
dealer to replace most vehicle light
bulbs. It is difficult to replace vehicle
light bulbs because other parts of the
vehicle must be removed before you
can get to the bulb. This is especially
true for removing the headlight
assembly to get to the bulb(s).
Removing/installing the headlight
assembly can result in damage to
the vehicle.
Information
After heavy driving, rain or washing
headlight and taillight lenses could
appear frosty. This condition is caused
by the temperature difference
between the lamp inside and outside.
This is similar to the condensation on
your windows inside your vehicle dur-
ing the rain and doesn’t indicate a
problem with your vehicle. If the
water leaks into the lamp bulb circuit-
ry, we recommend that the system be
checked by an authorized HYUNDAI
dealer.
Be sure to replace the burned-out
bulb with one of the same wattage
rating. Otherwise, it may cause dam -
age to the fuse or electric wiring sys-
tem.
i
Prior to replacing a light, depress
the foot brake, move the shift lever
into the P (Park, for Continuo usly
Variable Transaxle vehicle) or
neutral (for Manual Transaxle
vehicle), apply the parking brake,
plac e the ignition switch in the
LOCK/OFF position, and take the
key with you when leaving the
vehicle to av oid sudden move-
ment of the vehicle and to prevent
possible electric shock.
Be aware the bulbs may be h ot
and may burn your fingers.

$  "$# $Exterior careExterior general caution It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning
and caution statements that appear
on the label. High-pressure washing• When using high-pressure washers,
make sure to maintain sufficient dis-
tance from the vehicle.
Insufficient clearance or excessive
pressure can lead to component
damage or water penetration.
• Do not spray the camera, sensors or its surrounding area directly with a
high pressure washer. Shock appliedfrom high pressure water may cause
the device to not operate normally.• Do not bring the nozzle tip close to boots (rubber or plastic covers) or
connectors as they may be damaged
if they come into contact with high
pressure water.
Finish maintenanceWashing To help protect your vehicle’s finish
from rust and deterioration, wash it
thoroughly and frequently at least
once a month with lukewarm or cold
water.
If you use your vehicle for off-road
driving, you should wash it after each
off-road trip. Pay special attention to
the removal of any accumulation of
salt, dirt, mud, and other foreign
materials. Make sure the drain holes
in the lower edges of the doors and
rocker panels are kept clear and
clean.
Insects, tar, tree sap, bird droppings,
industrial pollution and similar
deposits can damage your vehicle’s
finish if not removed immediately.
Even prompt washing with plain
water may not completely remove all
these deposits. A mild soap, safe for
use on painted surfaces, may be
used.
After washing, rinse the vehicle thor-
oughly with lukewarm or cold water.
Do not allow soap to dry on the fin-
ish.
• Do not use strong soap, chemicaldetergents or hot water, and do not
wash the vehicle in direct sunlig ht
or when the body of the vehicle is
warm.
• Be careful when washing the side windows of your vehicle.
Especially, with high-pressure
water, water may leak through the
windows and wet the interior.
• To prevent dam age to the plastic
parts and lamps, do not clean with
chemical solvents or strong deter- gents. NOTICEWet brakes
After washing the vehicle, test the
brakes while driving slowly to see
if they have been affected by
water. If braking performance is
impaired, dry the brakes by apply-
ing them lightly while maint aining
a slow forward speed.

Recommended SAE viscosity
numberEngine oil viscosity (thickness) has
an effect on fuel economy and cold
weather operating (engine start and
engine oil flowability). Lower viscosi\b
ty engine oils can provide better fuel
economy and cold weather perform\b
ance, however, higher viscosity
engine oils are required for satisfac\b
tory lubrication in hot weather. Using oils of any viscosity other than
those recommended could result in
engine damage.
When choosing an oil, consider the
range of temperature your vehicle
will be operated in before the next oil
change. Proceed to select the rec\b
ommended oil viscosity from the
chart.
Always be sure to clean the area
around any filler plug, drain plug,
or dipstick before checking or
draining any lubricant. This is
especially important in dusty or
sandy areas and when the vehicle
is used on unpaved roads.
Cleaning the plug and dipstick
areas will prevent dirt and grit from
entering the engine and other
mechanisms that could be dam\b
aged.
