Emergency situations
Your vehicle is equipped with
emergency commodities to help you
respond to emergency situation.
Fire extinguisher
If there is small fire and you know how
to use the fire extinguisher, follow these
steps carefully.
1. Pull out the safety pin at the top of
the 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 extinguisher. 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 during
emergencies, when the vehicle is parked
by the roadside due to problems.
Tyre pressure gauge
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 firmly.
3. A firm non-leaking push will activate
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 2.
6. Reinstall the inflation valve cap.

Maintenance
Whilst operating your vehicle:

[Note any changes in the sound of the
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 looseness 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 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 engine
coolant 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
conditioning hoses for leaks or
damage.

[Check windscreen washer spray and
wiper operation. Clean wiper blades
with a clean cloth dampened with
washer fluid.

[Check headlight 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 bonnet
hinges.

[Lubricate door and bonnet locks and
latches.

[Lubricate door rubber weather strips.

[Lubricate door checker

[Check the air conditioning system.

[Inspect and lubricate automatic
transmission linkage and controls.

[Clean the battery and terminals.

[Check the brake fluid level.

Maintenance
The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is filled
at the factory.
Check the antifreeze protection and
coolant concentration level at least once
a year, at the beginning of the winter
season, and before travelling to a colder
climate.

WARNING
Do not remove a radiator cap/
engine coolant reservoir cap.

[Never attempt to remove the radiator
cap/engine coolant reservoir cap
whilst the engine is operating or hot.

[Doing so might lead to cooling
system failure and engine damage
and could result in serious personal
injury from escaping hot coolant or
steam.

[Turn the engine off and wait until
it cools down. Use extreme care
when removing the radiator cap/
engine coolant reservoir cap. Wrap
a thick towel around it, and turn it
counterclockwise slowly to the first
stop. Step back whilst the pressure is
released from the cooling system.
[When you are sure all the pressure
has been released, press down on the
cap, using a thick towel, and continue
turning counterclockwise to remove
it.

[Even if the engine is not operating,
do not remove the radiator cap/
engine coolant reservoir cap or the
drain plug whilst the engine and
radiator are hot. Hot coolant and
steam may still blow out under
pressure, causing serious injury.
WARNING
The electric motor (cooling
fan) is controlled by engine
coolant temperature,
refrigerant pressure and
vehicle speed.
It may sometimes operate even when
the engine is not running. Use extreme
caution when working near the blades
of the cooling fan so that you are not
injured by a rotating fan blades. As the
engine coolant temperature decreases,
the electric motor will automatically
shut off. This is a normal condition.
The electric motor (cooling fan) may
operate until you disconnect the
negative battery cable.

Maintenance
Recommended cold tyre
inflation 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 one mile (1.6 km).
Warm tyres normally exceed
recommended cold tyre pressures by 28
to 41 kPa (4 to 6 psi). Do not release air
from warm tyres to adjust the pressure
or the tyres will be under-inflated. For
recommended inflation pressure, refer
to “Tyre and Wheels” in chapter 2.
WARNING
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 control resulting in an
accident. This risk is much higher on
hot days and when driving for long
periods at high speeds.
NOTICE

[ 8QGHULQIODWLRQDOVRUHVXOWVLQ
excessive wear, poor handling
and reduced fuel economy. Wheel
deformation also is possible. Keep
your tyre pressures at the proper
levels. If a tyre frequently needs
refilling, we recommend that the
system be checked by a HYUNDAI
authorised repairer.

[ 2YHULQIODWLRQSURGXFHVDKDUVKULGH
excessive wear at the centre of the
tyre tread, and a greater possibility of
damage from road hazards.
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 cannot tell if
your tyres are properly inflated simply by
looking at them. Radial tyres may look
properly inflated even 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 pressure
measurement. If the cold tyre inflation
pressure matches the recommended
pressure on the tyre and loading
information label, no further adjustment
is necessary. If the pressure 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.

9-35
09
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 equalize tread wear, HYUNDAI
recommends that the tyres be rotated
every 10,000 miles (15,000 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 alignment,
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
specification and check lug nut tightness
(proper torque is 11~13kgf.m (79~94 lbf.
ft, 107~127N.m).

5. Maximum permissible inflation
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 maximum section
width.
For example:
TREADWEAR 200
TRACTION AA
TEMPERATURE A
7UHDGZHDU
The tread wear grade is a comparative
rating based on the wear rate of the tyre
when tested under controlled conditions
on a specified government test course.
For example, a tyre graded 150 would
wear one-and-a-half times (1½) as well
on the government 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.
7UDFWLRQ$$$% &
The traction grades, from highest to
lowest, are AA, A, B and C. Those grades
represent the tyre’s ability to stop on wet
pavement as measured under controlled
conditions on specified government
test surfaces of asphalt and concrete. A
tyre marked C may have poor traction
performance.
WARNING
The traction grade assigned to this tyre
is based on straight-ahead braking
traction tests, and does not include
acceleration, cornering, hydroplaning,
or peak traction characteristics.
