Maintenance
Filter inspection
The climate control air filter should be
replaced according to the Maintenance
Schedule. If the vehicle is operated in
severely air-polluted cities or on dusty
rough roads for a long period, it should
be inspected more frequently and
replaced earlier. When you replace the
climate control air filter, replace it by
performing the following procedure,
and be careful to avoid damaging other
components.
Replace the filter according to the
Maintenance Schedule.

WARNING
To prevent SERIOUS INJURY or DEATH
to you or bystanders, always follow
these precautions when working near
or handling the battery:
Always read and follow
instructions carefully when
handling a battery.
Wear eye protection designed
to protect the eyes from acid
splashes.
Keep all flames, sparks, or
smoking materials away from
the battery.
Hydrogen is always present in
battery cells, is highly
combustible, and may explode
if ignited.
%DWWHULHVFRQWDLQVXOIXULFDFLG
which is highly corrosive. Do
not allow acid to contact your
eyes, skin or clothing.
If acid gets into your eyes, flush your
eyes with clean water for at least 15
minutes and get immediate medical
attention. If acid gets on your skin,
thoroughly wash the area. If you
feel pain or a burning sensation, get
medical attention immediately.

[When lifting a plastic-cased battery,
excessive pressure on the case may
cause battery acid to leak. Lift with a
battery carrier or with your hands on
opposite corners.

[Do not attempt to jump start your
vehicle if your battery is frozen.

[NEVER attempt to recharge the
battery when the vehicle’s battery
cables are connected to the battery.

[The electrical ignition system works
with high voltage. NEVER touch these
components with the engine running
or when the Engine Start/Stop button
is in the ON position.

[Do not allow the (+) and (-) jumper
cables to touch. It may cause sparks.

[The battery may rupture or explode
when you jump start with a low or
frozen battery.

[Leaked battery electrolyte due to
repeated driving on sharp curves
(e.g. on circuits) may cause safety
problem. Avoid repeated driving on
sharp curves.
NOTICE
If you connect unauthorised electronic
devices to the battery, the battery may
be discharged. Never use unauthorised
devices.

WARNING
When recharging the battery, observe
the following precautions:

[ %HIRUHSHUIRUPLQJPDLQWHQDQFHRU
recharging the battery, turn off all
accessories and stop the engine.

[Do not allow cigarettes, sparks, or
flame near the battery.

[Wear eye protection when checking
the battery during charging.

[The battery must be removed from
the vehicle and placed in an area with
good ventilation.

[Watch the battery during charging,
and stop or reduce the charging
rate if the battery cells begin
gassing (boiling) violently or if the
temperature of the electrolyte of any
cell exceeds 49°C (120°F).

[The negative battery cable must be
removed first and installed last when
the battery is disconnected.

[Disconnect the battery charger in the
following order.
1. Turn off the main battery charger
switch.
2. Unhook the negative clamp from
the negative battery terminal.
3. Unhook the positive clamp from
the positive battery terminal.

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.

If the LED lamp does not operate,
we recommend that the system be
inspected by a HYUNDAI authorised
repairer. The LED lamps cannot be
replaced as a single unit because it is an
integrated unit.
The LED lamp has to be replaced with
the unit. Unless a skilled technician
checks or repairs the LED lamp, it may
damage related parts of the vehicle.

level. If you run out of petrol, it could
cause the engine to misfire and result
in excessive loading of the catalytic
converter.
Failure to observe these precautions
could result in damage to the catalytic
converter and to your vehicle.
Additionally, such actions could void
your warranties.
Petrol Particulate Filter (GPF)
(if equipped)
The Petrol Particulate Filter (GPF) system
removes the soot in the exhaust gas.
The GPF system automatically burns
(or oxidizes) the accumulated soot in
accordance with driving situations,
unlike a disposable air filter.
In other words, the accumulated soot is
automatically purged out by the engine
control system and by the high exhaust-
gas temperature at normal/ high driving
speeds.
However, when the vehicle is continually
driven at repeated short distances or
driven at low speed for a long time,
the accumulated soot may not be
automatically removed because of low
exhaust gas temperature. In this case,
the accumulated soot may reach a
certain amount regardless of the soot
oxidization process, then the GPF lamp
will illuminate.
The Petrol Particulate Filter (GPF) Lamp
stops illuminating, when the driving
speed exceeds 80 km/h (50 mph) with
the engine at 1,500- 4,000 rpm and the
gear in the 3rd position or above for
approximately 30 minutes.When the GPF lamp starts to blink or
the waning message “Check exhaust
system” pops up even though the
vehicle was driven as mentioned above,
we recommend that you have the
GPF system checked by a HYUNDAI
authorised repairer.
With the GPF lamp blinking for an
extended period of time, it may damage
the GPF system and lower the fuel
economy.
WARNING
Petrol Fuel
(if equipped with GPF)
We recommend you to use only the
regulated petrol fuels, when your
vehicle is equipped with the GPF
system.
When you use other petrol fuels which
contain unspecified additives, they
may damage the GPF system and cause
exhaust emission problems.
