What to do in an emergencyTyre pressure sensor
(if equipped with TPMS)
The sealant on the tyre pres-
sure sensor and wheel should
be removed when you replace
the tyre with a new one and
inspect the tyre pressure sen-
sors at an authorised repairer.
CAUTION
The tyre inflation pressure must
be at least 220 kPa (32 psi). If it
is not, do not continue driving.
Call for road side service or
towing.

What to do in an emergency
6
Your vehicle is equipped with emer-
gency commodities to help you
respond to emergency situation.
Fire extinguisher
If there is small fire and you know
how to use the fire extinguisher, fol-
low these steps carefully.
1. Pull out the safety pin at the top ofthe extinguisher that keeps the
handle from being accidentally
pressed.
2. Aim the nozzle towards the base of the fire.
3. Stand approximately 2.5 m (8 ft) away from the fire and squeeze
the handle to discharge the extin-
guisher. If you release the handle,
the discharge will stop.
4. Sweep the nozzle back and forth at the base of the fire. After the fire
appears to be out, watch carefully
since it may re-ignite.
First aid kit
Supplies for use in giving first aid
such as scissors, bandage and
adhesive tape, etc. are provided.
Triangle reflector
Place the triangle reflector on the
road to warn oncoming vehicles dur-
ing emergencies, such as when the
vehicle is parked by the roadside due
to problems.
Tyre pressure gauge
(if equipped)
Tyres normally lose some air in day-
to-day use, and you may have to add
a air periodically and usually it is not
a sign of a leaking tyre, but of normal
wear. Always check tyre pressure
when the tyres are cold because tyre
pressure increases with temperature. To check the tyre pressure, take the
following steps:
1. Unscrew the inflation valve cap
that is located on the rim of the
tyre.
2. Press and hold the gauge against the tyre valve. Some air will leak
as you begin and more will leak if
you don't press the gauge in firm-
ly.
3. A firm non-leaking push will acti- vate the gauge.
4. Read the tyre pressure on the gauge to see whether the tyre
pressure is low or high.
5. Adjust the tyre pressure to the specified pressure. Refer to "Tyres
and Wheels" in chapter 8.
6. Reinstall the inflation valve cap.

Maintenance
Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check the coolant level in theengine coolant reservoir.
Check the windscreen washer fluid level.
Check for low or under-inflated tyres.
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 posi-
tion.
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.
Be careful when checking your
engine coolant/inverter coolant
level when the engine is hot.
This may result in coolant being
blown out of the opening and
cause serious burns and other
injuries.

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
recommended for your vehicle.
(Continued)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.
(Continued)
WARNING

7-30
Maintenance
All specifications (sizes and pres-
sures) can be found on a label
attached to the driver’s side centre
pillar.
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 driven less than
1 mi. (1.6 km).
Warm tyres normally exceed recom-
mended cold tyre pressures by 4 to 6
psi (28 to 41 kPa). 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.

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.
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.

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.
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.
