Maintenance
Whilst operating your vehicle:
• Note any changes in the sound ofthe exhaust or any smell of exhaust
fumes in the vehicle.
• Check for vibrations in the steering wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead position.
• Notice if your vehicle constantly turns slightly or “pulls” to one side when
travelling on smooth, level road.
• When stopping, listen and check for unusual sounds, pulling to one side,
increased brake pedal travel or
“hard-to-push” brake pedal.
• If any slipping or changes in the operation of your transmission
occurs, check the transmission fluid
level.
• Check the dual clutch transmission P (Park) function.
• Check the parking brake.
• Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
• Check coolant level in the enginecoolant reservoir.
• Check the operation of all exterior lights, including the stoplights, turn
signals and hazard warning flashers.
• Check the inflation pressures of all tyres including the spare for tyres
that are worn, show uneven wear,
or are damaged.
• Check for loose wheel lug nuts.
At least twice a year: (i.e., every Spring and Autumn)
• Check radiator, heater and air condi-
tioning hoses for leaks or damage.
• Check windscreen washer spray and wiper operation. Clean wiper
blades with a clean cloth damp-
ened with washer fluid.
• Check headlamp alignment.
• Check muffler, exhaust pipes, shields and clamps.
• Check the seat belts for wear and function.
At least once a year:
• Clean body and door drain holes.
• Lubricate door hinges and bonnethinges.
• Lubricate door and bonnet locks and latches.
• Lubricate door rubber weather strips.
• Check the air conditioning system.
• Inspect and lubricate dual clutch transmission linkage and controls.
• Clean the battery and terminals.
• Check the brake fluid level.

TYRES AND WHEELS
Tyre care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tyre
inflation pressures and stay within the
load limits and weight distribution rec-
ommended for your vehicle.
All specifications (sizes and pressures)
can be found on a label attached to the
driver’s side centre pillar.•Replace tyres that are worn,
show uneven wear, or are dam-
aged. Worn tyres can cause
loss of braking effectiveness,
steering control, or traction.
•ALWAYS replace tyres with
the same size as each tyre
that was originally supplied
with this vehicle. Using tyres
and wheels other than the rec-
ommended sizes could cause
unusual handling characteris-
tics, poor vehicle control, or
negatively affect your vehi-
cle’s Anti-Lock Brake System
(ABS) resulting in a serious
accident.
Tyre failure may cause loss of
vehicle control resulting in an
accident. To reduce risk of
SERIOUS INJURY or DEATH,
take the following precautions:
•Inspect your tyres monthly for
proper inflation as well as
wear and damage.
•The recommended cold tyre
pressure for your vehicle can
be found in this manual and on
the tyre label located on the
driver’s side centre pillar.
Always use a tyre pressure
gauge to measure tyre pres-
sure. Tyres with too much or
too little pressure wear
unevenly causing poor han-
dling.
•Check the pressure of the
spare every time you check
the pressure of the other tyres
on your vehicle.

Maintenance
Recommended cold tyre infla-
tion pressures
All tyre pressures (including the
spare) should be checked when the
tyres are cold. “Cold tyres” means
the vehicle has not been driven for at
least three hours or has been driven
for less than 1 mile (1.6 km).
Warm tyres normally exceed recom-
mended cold tyre pressures by 28 to
41 kPa (4 to 6 psi). Do not release air
from warm tyres to adjust the pres-
sure or the tyres will be under-inflat-
ed. For recommended inflation pres-
sure, refer to “Tyre and Wheels” in
chapter 8.Recommended pressures must
be maintained for the best ride,
vehicle handling, and minimum
tyre wear.
Over-inflation or under-inflation
can reduce tyre life, adversely
affect vehicle handling, and
lead to sudden tyre failure that
could result in loss of vehicle
control resulting in an accident.
Severe under-inflation can lead
to severe heat build-up, causing
blowouts, tread separation and
other tyre failures that can
result in the loss of vehicle con-
trol resulting in an accident.
This risk is much higher on hot
days and when driving for long
periods at high speeds.
WARNING
•Under-inflation results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation is also
possible. Keep your tyre pres-
sures at the proper levels. If a
tyre frequently needs refilling,
we recommend it be checked
by a HYUNDAI authorised
repairer.
•Over-inflation produces a
harsh ride, excessive wear at
the centre of the tyre tread,
and a greater possibility of
damage from road hazards.

Maintenance
Check tyre inflation pressure
Check your tyres, including the spare
tyre, once a month or more.
How to check
Use a good quality tyre pressure
gauge to check tyre pressure. You
can not tell if your tyres are properly
inflated simply by looking at them.
Radial tyres may look properly inflat-
ed when they are under-inflated.
Remove the valve cap from the tyre
valve stem. Press the tyre gauge
firmly onto the valve to get a pres-
sure measurement. If the cold tyre
inflation pressure matches the rec-
ommended pressure on the tyre and
loading information label, no further
adjustment is necessary. If the pres-
sure is low, add air until you reach
the recommended pressure. Make
sure to put the valve caps back on
the valve stems. Without the valve
cap, dirt or moisture could get into
the valve core and cause air leakage.
If a valve cap is missing, install a new
one as soon as possible.If you overfill the tyre, release air by
pushing on the metal stem in the
centre of the tyre valve. Recheck the
tyre pressure with the tyre gauge. Be
sure to put the valve caps back on
the valve stems. Without the valve
cap, dirt or moisture could get into
the valve core and cause air leakage.
If a valve cap is missing, install a new
one as soon as possible.
Tyre rotation
To equalise tread wear, HYUNDAI
recommends that the tyres be rotat-
ed every 7,500 miles (12,000 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 the tyre. Replace the tyre if you
find any 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]).

Maintenance
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 : 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 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 1517 represents
that the tyre was produced in the
15th week of 2017.
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
Temperature - A, B & C
The temperature grades are A (the
highest), then B and C representing
the tyre’s resistance to the genera-
tion of heat and its ability to dissipate
heat when tested under controlled
conditions on a specified indoor lab-
oratory 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 law.
Low aspect ratio tyres
A low aspect ratio tyre, of which the
aspect ratio is lower than 50, is
designed for a sporty-look vehicle.
The low aspect ratio is to optimize
handling and braking. Thus, it may
be uncomfortable to ride and it may
generate noises, in comparison with
a normal tyre.•When there is an impact on a
tyre, inspect the tyre condi-
tion or contact a HYUNDAI
authorised repairer.
•Inspect the tyre condition and
pressure every 1,800 miles
(3,000 km) to prevent 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.
The temperature grade for this
tyre is established for a tyre that
is properly inflated and not
overloaded. Excessive speed,
under-inflation, over-inflation,
or excessive loading, either
separately or in combination,
can cause heat build-up and
possible sudden tyre failure.
This may cause loss of vehicle
control resulting in an accident.
WARNING
The side wall of a low aspect
ratio tyre is shorter than the
normal one. Thus, the low-
aspect wheel and tyre are easily
damaged. 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.

TYRES AND WHEELS
When replacing tyres, use the same size originally supplied with the vehicle.
Using tyres of a different size can damage the related parts or make it work irregularly.
CAUTION
• It is permissible to add 20 kPa (3 psi) to the standard tyre pressure specification if colder temperatures are expected soon. Tyres typically lose 7 kPa (1 psi) for every 7°C (12°F) temperature drop. If extreme tempera-
ture 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: +10 kPa/1 km (+2.4 psi/1 mile)).
• Must do not exceed maximum inflation pressure shown on equipped tyre sidewall.
