Maintenance
Tyre rotation
To equalize tread wear, HYUNDAI
recommends that the tyres be rotat-
ed every 6,000 miles (10,000 km) or
sooner if irregular wear develops.
During rotation, check the tyres for
correct balance.
When rotating tyres, check for
uneven wear and damage. Abnormal
wear is usually caused by incorrect
tyre pressure, improper wheel align-
ment, out-of-balance wheels, severe
braking or severe cornering. Look for
bumps or bulges in the tread or side
of tyre. Replace the tyre if you find
either of these conditions. Replace
the tyre if fabric or cord is visible.
After rotation, be sure to bring the
front and rear tyre pressures to spec-
ification and check lug nut tightness
(proper torque is
11~13 kgf·m [79~94 lbf·ft]).Disc brake pads should be inspected
for wear whenever tyres are rotated.
Information
The outside and inside of the unsym-
metrical tyre is distinguishable. When
installing an unsymmetrical tyre, be
sure to install the side marked "out-
side" face the outside. If the side
marked "inside" is installed on the
outside, it will have a bad effect on
vehicle performance.

■ With a full-size spare tyre (if equipped)
■Without a spare tyre
Do not use the compact spare
tyre for tyre rotation.
Do not mix bias ply and radial
ply tyres under any circum-
stances. This may cause
unusual handling characteris-
tics that may cause loss of
vehicle control resulting in an
accident.

Tyre speed ratings
The chart below lists many of the dif-
ferent speed ratings currently being
used for passenger car 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 oper-
ating speed.
3. Checking tyre life (TIN : TyreIdentification Number)
Any tyres that are over six years old,
based on the manufacturing date,
(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 num-
bers on a tyre consisting of numbers
and English letters. The manufactur-
ing date is designated 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 1518 represents
that the tyre was produced in the
15th week of 2018.
4. Tyre ply composition andmaterial
The number of layers or plies of rub-
ber-coated fabric in the tyre. Tyre
manufacturers also must indicate the
materials in the tyre, which include
steel, nylon, polyester, and others.
The letter "R" means radial ply con-
struction; the letter "D“ means diago-
nal or bias ply construction; and the
letter "B" means belted-bias ply con-
struction.
5. Maximum permissible infla-tion pressure
This number is the greatest amount
of air pressure that should be put in
the tyre. Do not exceed the maximum
permissible inflation pressure. Refer
to the Tyre and Loading Information
label for recommended inflation
pressure.

Maintenance
The side wall of a low aspect
ratio tyre is shorter than the
nor- mal one. Thus, the low-
aspect wheel and tyre are easily
dam- aged. Follow the below
instructions.
When driving on a rough road
or driving off a road, be care-
ful not to damage the tyres
and wheels. After driving,
inspect the tyres and wheels.
When passing over a pothole,
speed bump, manhole, or kerb
stone, slowly drive the vehicle
not to damage the tyres and
wheels.
When there is an impact on a
tyre, inspect the tyre condi-
tion. Or, we recommend that
you contact a HYUNDAI
authorised repairer.(Continued)
CAUTION(Continued)
Inspect the tyre condition and
pressure every 1,800 miles
(3,000 km) to prevent a tyre
damage.
It is difficult to recognise a tyre
damage only with your eyes.
When there is a slight hint of a
tyre damage, check and
replace the tyre to prevent the
damage caused by air leakage.
When a tyre is damaged
whilst driving on a rough
road, off a road, or over obsta-
cles, such as a pothole, man-
hole, or kerb stone, your war-
ranty does not cover the dam-
age.
The tyre information is speci-
fied on the tyre side wall.

Maintenance
Headlamp aiming
Headlamp aiming
1. Inflate the tyres to the specifiedpressure and remove any loads
from the vehicle except the driver,
spare tyre, and tools.
2. The vehicle should be placed on a flat floor.
3. Draw vertical lines (Vertical lines passing through respective head
lamp centres) and a horizontal line
(Horizontal line passing through
centre of head lamps) on the
screen. 4. With the headlamp and battery in
normal condition, aim the head-
lamps so the brightest portion falls
on the horizontal and vertical
lines.
5. To aim the low beam left or right, turn the driver clockwise or coun-
terclockwise. To aim the low beam
up or down, turn the driver clock-
wise or counterclockwise.
To aim the high beam up or down,turn the driver clockwise or coun-
terclockwise.

When replacing tyres, use the same size originally supplied with the vehicle.
Using tyres of a different size can damage the related parts or not work properly.
CAUTION
*1 : Normal load : Up to 3 persons
It is permissible to add 3 psi (20 kPa) to the standard tyre pressure specification if colder temperatures are expected soon. Tyres typically lose 1 psi (7 kPa) for every 7°C (12°F) temperature drop. If extreme temperature
variations are expected, recheck your tyre pressure as necessary to keep them properly inflated.
An air pressure generally decreases, as you drive up to a high-altitude area above sea level. Thus, if you plan to drive a high-altitude area, check the tyre pressures in advance. If necessary, inflate them to a proper level
(Air inflation per altitude: +2.4 psi/1 mile (+10 kPa/1 km).
