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.
J - Rim contour designation.
16 - Rim diameter in inches.
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 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 shows 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 1519 represents
that the tyre was produced in the
15th week of 2019.

4. Tyre ply composition and
material
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.
6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that
can be carried by the tyre. When
replacing the tyres on the vehicle,
always use a tyre that has the same
load rating as the factory installed
tyre.
7. Uniform tyre quality grading
Quality grades can be found where
applicable on the tyre sidewall
between tread shoulder and maxi-
mum section width.
For example:
TREADWEAR 200
TRACTION AA
TEMPERATURE A
Tread wear
The tread wear grade is a compara-
tive rating based on the wear rate of
the tyre when tested under controlled
conditions on a specified govern-
ment test course. For example, a tyre
graded 150 would wear one-and-a-
half times (1½) as well on the gov-
ernment course as a tyre graded
100.
The relative performance of tyres
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
sidewalls of passenger vehicle tyres.
The tyres available as standard or
optional equipment on your vehicle
may vary with respect to grade.

Consult an authorised 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 headlamp
assembly to get to the bulb(s).
Removing/installing the headlamp
assembly can result in damage to
the vehicle.Be sure to replace the burned-out
bulb with one of the same wattage
rating. Otherwise, it may cause
damage to the fuse or electric
wiring system.
Information
The headlamp and tail lamp lenses
could appear frosty if the vehicle is
washed after driving or the vehicle is
driven at night in wet weather. This
condition is caused by temperature dif-
ference between the lamp inside and
outside and, it does not indicate a prob-
lem with your vehicle. When moisture
condenses in the lamp, it will be
removed after driving with the head-
lamp on. The removable level may dif-
fer depending on lamp size, lamp posi-
tion and environmental condition.
However, if moisture is not removed,
we recommend that your vehicle is
inspected by an authorised HYUNDAI
dealer.
Information
• A normally functioning lamp may
flicker momentarily to stabilize the
vehicle’s electrical control system.
However, if the lamp goes out after
flickering momentarily, or contin-
ues to flicker, we recommend the
system be checked by an authorised
HYUNDAI dealer.
• The position lamp may not turn on
when the position lamp switch is
turned on, but the position lamp and
headlamp switch may turn on when
the headlamp switch is turned on.
This may be caused by network fail-
ure or vehicle electrical control sys-
tem malfunction. If this occurs, we
recommend the system be checked
by an authorised HYUNDAI dealer.

NOTICE
Prior to working on a light, firmly
apply the parking brake, ensure
that the ignition switch is in the
LOCK/OFF position and turn off
the lights to avoid sudden move-
ment of the vehicle and burning
your fingers or receiving an elec-
tric shock.

Maintenance
Do not use strong soap, chemi-
cal detergents or hot water, and
do not wash the vehicle in direct
sunlight 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 damage to the plastic
parts, do not clean with chemi-
cal solvents or strong deter-
gents.
To prevent damage to the charg-
ing door, make sure to close and
lock the vehicle doors when
washing (high-pressure wash-
ing, automatic car washing, etc.)
the vehicle.
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
applied from 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 dam-
aged if they come into contact with
high pressure water. Water washing in the engine
compartment including high
pressure water washing may
cause the failure of electrical cir-
cuits located in the engine com-
partment.
Never allow water or other liq-
uids to come in contact with
electrical/electronic compo-
nents inside the vehicle as this
may damage them.

Specifications & Consumer information
Recommended SAE viscosity
number
Always be sure to clean the area
around any filler plug, drain
plug, or dipstick before check-
ing 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 damaged.
CAUTION
Engine oil viscosity (thickness) has an effect on fuel economy and cold
weather operating (engine start and engine oil flowability). Lower viscosity
engine oils can provide better fuel economy and cold weather performance,
however, higher viscosity engine oils are required for satisfactory 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 recommended
oil viscosity from the chart.
