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.
Tyre traction
Tyre traction can be reduced if you
drive on worn tyres, tyres that are
improperly inflated or on slippery
road surfaces. Tyres 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.
Tyre maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease
tyre wear. If you find a tyre is worn
unevenly, have your dealer check the
wheel alignment.
When you have new tyres installed,
make sure they are balanced. This
will increase vehicle ride comfort and
tyre life. Additionally, a tyre should
always be rebalanced if it is removed
from the wheel.
Tyre sidewall labeling
This information identifies and
describes the fundamental charac-
teristics of the tyre and also provides
the tyre identification number (TIN)
for safety standard certification. The
TIN can be used to identify the tyre in
case of a recall.

2. Tyre size designation
A tyre’s sidewall is marked with a tyre
size designation. You will need this
information when selecting replace-
ment tyres for your vehicle. The fol-
lowing explains what the letters and
numbers in the tyre size designation
mean.
Example tyre size designation:
(These numbers are provided as an
example only; your tyre size designa-
tor could vary depending on your
vehicle.)205/65R16 95H

Tyre speed ratings
The chart below lists many of the dif-
ferent speed ratings currently being
used for passenger vehicle tyres.
The speed rating is part of the tyre
size designation on the sidewall of
the tyre. This symbol corresponds to
that tyre's designed maximum safe
operating speed.
3. Checking tyre life
(TIN : Tyre Identification
Number)
Any tyres that are over 6 years old,
based on the manufacturing date,
tyre strength and performance,
decline with age naturally (even
unused spare tyres). Therefore, the
tyres (including the spare tyre)
should be replaced by new ones. You
can find the manufacturing date on
the tyre sidewall (possibly on the
inside of the wheel), displaying the
DOT Code. The DOT Code is a
series of numbers on a tyre consist-
ing of numbers and English letters.
The manufacturing date is designat-
ed by the last four digits (characters)
of the DOT code.
DOT : XXXX XXXX OOOO
The front part of the DOT means a
plant code number, tyre size and
tread pattern and the last four num-
bers indicate week and year manu-
factured.
For example:
DOT XXXX XXXX 1614 represents
that the tyre was produced in the
16th week of 2014.Tyre age
Tyres degrade over time, even
when they are not being used.
Regardless of the remaining
tread, it is recommended that
tyres generally be replaced
after six (6) years of normal
service. Heat caused by hot cli-
mates or frequent high loading
conditions can accelerate the
aging process. Failure to follow
this Warning can result in sud-
den tyre failure, which could
lead to a loss of control and an
accident involving serious
injury or death.

Traction - AA, A, B & C
The traction grades, from highest to
lowest, are AA, A, B and C. Those
grades represent the tyres ability to
stop on wet pavement as measured
under controlled conditions on spec-
ified government test surfaces of
asphalt and concrete. A tyre marked
C may have poor traction perform-
ance.
Temperature - A, B & C
The temperature grades are A (the
highest), B and C representing the
tyre’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can
cause the material of the tyre to
degenerate and reduce tyre life, and
excessive temperature can lead to
sudden tyre failure. Grades B and A
represent higher levels of perform-
ance on the laboratory test wheel
than the minimum required by the
law.Tyre temperature
The temperature grade for this
tyre is established for a tyre that
is properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive
loading, either separately or in
combination, can cause heat
build-up and possible sudden
tyre failure. This can cause loss
of vehicle control and serious
injury or death.WARNING
The traction grade assigned to
this tyre is based on straight-
ahead braking traction tests,
and does not include accelera-
tion, cornering, hydroplaning,
or peak traction characteristics.

Maintenance
Low aspect ratio tyre
(if equipped)
Low aspect ratio tyres, whose aspect
ratio is lower than 50, are provided
for a sporty apperance.
Because the low aspect ratio tyres
are optimized for handling and brak-
ing, the vehicle may be more uncom-
fortable to travel in and there may be
more noise compared with normal
tyres.Because the sidewall of the low
aspect ratio tyre is shorter than
the normal, the wheel and tyre
of the low aspect ratio tyre is
more easily damaged. So, fol-
low the instructions below.
- When driving on a rough road
or off road, drive cautiously
because tyres and wheels may
be damaged. And after driving,
inspect tyres and wheels.
- When passing over a pothole,
speed bump, manhole, or kerb
stone, drive slowly so that the
tyres and wheels are not dam-
aged.
- If the tyre is impacted, we rec-
ommend that you inspect the
tyre condition or contact an
authorised HYUNDAI dealer.
- To prevent damage to the tyre,
inspect the tyre condition and
pressure every 3,000km.
CAUTION
•It is not easy to recognise tyre
damage visually. But if there
is the slightest hint of tyre
damage, even though you
cannot see it, have the tyre
checked or replaced as the
damage may lead to air leak-
age from the tyre.
•If the tyre is damaged by driv-
ing on a rough road, off road,
pothole, manhole, or kerb
stone, it will not be covered by
the warranty.
•You can find out the tyre infor-
mation on the tyre sidewall.

Maintenance
Finish damage repair
Deep scratches or stone chips in the
painted surface must be repaired
promptly. Exposed metal will quickly
rust and may develop into a major
repair expense.
If your vehicle is damaged and
requires any metal repair or
replacement, be sure the body
shop applies anti-corrosion mate-
rials to the parts repaired or
replaced.
Bright-metal maintenance
• To remove road tar and insects,
use a tar remover, not a scraper or
other sharp object.
• To protect the surfaces of bright-
metal parts from corrosion, apply a
coating of wax or chrome preser-
vative and rub to a high lustre.
• During winter weather or in coastal
areas, cover the bright metal parts
with a heavier coating of wax or
preservative. If necessary, coat the
parts with non-corrosive petroleum
jelly or other protective compound.
Underbody maintenance
Corrosive materials used for ice and
snow removal and dust control may
collect on the underbody. If these
materials are not removed, acceler-
ated rusting can occur on underbody
parts such as the fuel lines, frame,
floor pan and exhaust system, even
though they have been treated with
rust protection.
Thoroughly flush the vehicle under-
body and wheel openings with luke-
warm or cold water once a month,
after off-road driving and at the end
of each winter. Pay special attention
to these areas because it is difficult
to see all the mud and dirt. It will do
more harm than good to wet down
the road grime without removing it.
The lower edges of doors, rocker
panels, and frame members have
drain holes that should not be
allowed to clog with dirt; trapped
water in these areas can cause rust-
ing.

Aluminium wheel maintenance
The aluminium wheels are coated
with a clear protective finish.
Corrosion protection
Protecting your vehicle from corro-
sion
By using the most advanced design
and construction practices to combat
corrosion, we produce vehicles of
the highest quality. However, this is
only part of the job. To achieve the
long-term corrosion resistance your
vehicle can deliver, the owner's
cooperation and assistance is also
required.
Common causes of corrosion
The most common causes of corro-
sion on your vehicle are:
• Road salt, dirt and moisture that is
allowed to accumulate underneath
the vehicle.
• Removal of paint or protective
coatings by stones, gravel, abra-
sion or minor scrapes and dents
which leave unprotected metal
exposed to corrosion. After washing the vehicle, test
the brakes whilst driving slowly
to see if they have been affected
by water. If braking performance
is impaired, dry the brakes by
applying them lightly whilst
maintaining a slow forward
speed.
WARNING
•Do not use any abrasive
cleaner, polishing compound,
solvent, or wire brushes on
aluminium wheels.
•Clean the wheel when it has
cooled.
•Use only a mild soap or neu-
tral detergent, and rinse thor-
oughly with water. Also, be
sure to clean the wheels after
driving on salted roads.
•Do not wash the wheels with
high-speed car wash brushes.
•Do not use any cleanser con-
taining acid or alkaline deter-
gents.

Interior care
Interior general precautions
Prevent chemicals such as perfume,
cosmetic oil, sun cream, hand clean-
er and air freshener from contacting
the interior parts because they may
cause damage or discolouration. If
they do contact the interior parts,
wipe them off immediately.
See the instructions that follow for
the proper way to clean vinyl.
Cleaning the upholstery and
interior trim
Vinyl
Remove dust and loose dirt from
vinyl with a whisk broom or vacuum
cleaner. Clean vinyl surfaces with a
vinyl cleaner.
Fabric
Remove dust and loose dirt from fab-
ric with a whisk broom or vacuum
cleaner. Clean with a mild soap solu-
tion recommended for upholstery or
carpets. Remove fresh spots imme-
diately with a fabric spot cleaner. If
fresh spots do not receive immediate
attention, the fabric can be stained
and its colour can be affected. Also,
its fire-resistant properties can be
reduced if the material is not proper-
ly maintained. Never allow water or other liq-
uids to come in contact with
electrical/electronic compo-
nents inside the vehicle as this
may damage them.
CAUTION
When cleaning leather products
(steering wheel, seats etc.), use
neutral detergents or low alco-
hol content solutions. If you use
high alcohol content solutions
or acid/alkaline detergents, the
colour of the leather may fade
or the surface may get stripped
off.
CAUTION
Using anything but recom-
mended cleaners and proce-
dures may affect the fabric’s
appearance and fire-resistant
properties.
