Maintenance
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in the
maintenance schedule. If the vehicle
is being driven in severe conditions,
more frequent oil and filter changes are
required.
Drive belts
Inspect all drive belts for evidence
of cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked
periodically for proper tension and
adjusted as necessary.
CAUTION
When you are inspecting the belt, place
the ignition switch to the lock/off or
ACC position.
Fuel filter (Except Europe)
A clogged filter can limit the speed
at which the vehicle may be driven,
damage the emission system and cause
multiple issues such as hard starting.
If an excessive amount of foreign
matter accumulates in the fuel tank, the
filter may require replacement more
frequently.
After installing a new filter, run the
engine for several minutes, and
check for leaks at the connections.
We recommend that the fuel filter be
replaced by a HYUNDAI authorised
repairer.
Fuel filter (For Europe)
This petrol powered vehicle is equipped
with a lifetime fuel filter that is
integrated with the fuel tank. Regular
maintenance or replacement is not
needed; however, the quality of fuel
used may impact the frequency of
maintenance needed. If there are any
fuel related problems like fuel flow
restriction, surging, loss of power,
hard starting problem etc, fuel filter
inspection or replacement may be
needed. We recommend the fuel filter
be inspected or replaced by a HYUNDAI
authorised repairer.
Fuel lines, fuel hoses and
connections
Check the fuel lines, fuel hoses and
connections for leakage and damage.
We recommend that the fuel lines, fuel
hoses and connections be replaced by a
HYUNDAI authorised repairer.
Vapour hose and fuel filler cap
The vapour hose and fuel filler cap
should be inspected at those intervals
specified in the maintenance schedule.
Make sure that a new vapour hose or
fuel filler cap is correctly replaced.

Vacuum crankcase ventilation
hoses (if equipped)
Inspect the surface of hoses for
evidence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterioration.
Particular attention should be paid to
examine those hose surfaces nearest to
high heat sources, such as the exhaust
manifold.
Inspect the hose routing to assure that
the hoses do not come in contact with
any heat source, sharp edges or moving
component which might cause heat
damage or mechanical wear. Inspect
all hose connections, such as clamps
and couplings, to make sure they are
secure, and that no leaks are present.
Hoses should be replaced immediately if
there is any evidence of deterioration or
damage.
Air cleaner filter
We recommend that the air cleaner filter
be replaced by a HYUNDAI authorised
repairer.

Make sure to install new spark plugs of
the correct heat range.
When assembling parts, be sure to
wipe out foreign substances inside
and outside of the boot bottom of the
ignition coil and the insulator of the
spark plug with a soft cloth to prevent
contamination of the spark plug
insulator.
WARNING
Do not disconnect and inspect spark
plugs when the engine is hot. You may
burn yourself.
Cooling system
Check the cooling system parts, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.

Checking the engine oil and
filter
[ We recommend that the engine oil
and filter be replaced by a HYUNDAI
authorised repairer.
[ If the maintenance schedule to
replace engine oil is exceeded,
the engine oil performance may
deteriorate, and the engine condition
may be affected. Therefore, replace
the engine oil according to the
maintenance schedule.
[ To keep the engine in optimal
condition, use the recommended
engine oil and filter. If the
recommended engine oil and filter are
not used replace it according to the
maintenance schedule under severe
usage conditions.
[ The purpose of the maintenance
schedule for engine oil replacement
is to prevent oil deterioration and it is
irrelevant to oil consumption. Check
and refill engine oil regularly.
WARNING
Used engine oil may cause irritation or
cancer of the skin if left in contact with
the skin for prolonged periods of time.
Used engine oil contains chemicals
that have caused cancer in laboratory
animals. Always protect your skin
by washing your hands thoroughly
with soap and warm water as soon as
possible after handling used oil.

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.

The coolant level should be filled
between [F (Full)] and [L (Low)] marked
on the side of the coolant reservoir when
the engine is cool.
If the coolant level is low, add enough
distilled (deionized) water.
Bring the level to [F(Full)], but do
not overfill. If frequent additions are
required, we recommend that the
system be inspected by a HYUNDAI
authorised repairer.

Maintenance
Checking the brake/clutch fluid
level
OBC3090016R
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the left
or right side of the reservoir.
Before removing the reservoir cap
and adding brake/clutch fluid, clean
the area around the reservoir cap
thoroughly to prevent brake/clutch fluid
contamination.
If the level is low, add fluid to the MAX
level. The level will fall with accumulated
mileage. This is a normal condition
associated with the wear of the brake
linings.
If the fluid level is excessively low,
we recommend that the system be
checked by a HYUNDAI authorised
repairer.

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).

WARNING
To reduce the risk of DEATH or SERIOUS
INJURY:
[ Replace tyres that are worn, show
uneven wear, or are damaged. Worn
tyres can cause loss of braking
effectiveness, steering control, and
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
recommended sizes could cause
unusual handling characteristics,
poor vehicle control, or negatively

accident.
[ When replacing tyres (or wheels), it
is recommended to replace the two
front or two rear tyres (or wheels)
as a pair. Replacing just one tyre
can seriously affect your vehicle’s
handling.
[ Tyres degrade over time, even when
they are not being used. Regardless
of the remaining tread, HYUNDAI
recommends that tyres be replaced
after six (6) years of normal service.
[ Heat caused by hot climates or
frequent high loading conditions can
accelerate the aging process. Failure
to follow this warning may cause
sudden tyre failure, which could lead
to a loss of vehicle control resulting
in an accident.
Compact spare tyre replacement
(if equipped)
A compact spare tyre has a shorter
tread life than a regular size tyre.
Replace it when you can see the
tread wear indicator bars on the tyre.
The replacement compact spare tyre
should be the same size and design
tyre as the one provided with your new
vehicle and should be mounted on the
same compact spare tyre wheel. The
compact spare tyre is not designed to
be mounted on a regular size wheel,
and the compact spare tyre wheel is not
designed for mounting a regular size
tyre.
WARNING
The original tyre should be repaired or
replaced as soon as possible to avoid
failure of the spare and loss of vehicle
control resulting in an accident. The
compact spare tyre is for emergency
use only. Do not operate your vehicle
over 50 mph (80 km/h) when using the
compact spare tyre.

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
7 U H D G Z H D U
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.
7 U D F W L R Q $ $ $ % &
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.
Page 600 of 649
9-41
09
7 H P S H U D W X U H $ % &
The temperature grades are A (the
highest), B and C representing the tyre’s
resistance to the generation of heat
and its ability to dissipate heat when
tested under controlled conditions on a
specified indoor laboratory 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 performance on the laboratory
test wheel than the minimum required
by law.
WARNING
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.
Low aspect ratio tyres
Low aspect ratio tyres, the aspect ratio
is lower than 50, are provided for sporty
looks.
Because low aspect ratio tyres are
optimized for handling and braking, their
sidewall is a little stiffer than a standard
tyre. Also, low aspect ratio tyres tend to
be wider so that they consequently have
a greater contact patch with the road
surface. In some instances, they may
generate more road noise compared
with standard tyres.
