Maintenance
You should exercise the utmost care
to prevent damage to your vehicle and
injury to yourself whenever performing
any maintenance or inspection
procedures.
We recommend you have your vehicle
maintained and repaired by a HYUNDAI
authorised repairer. A HYUNDAI
authorised repairer meets HYUNDAI’s
high service quality standards and
receives technical support from
HYUNDAI in order to provide you with a
high level of service satisfaction.
Owner’s responsibility
Maintenance service and record
retention are the owner’s responsibility.
You should retain documents that show
proper maintenance has been performed
on your vehicle in accordance with
the scheduled maintenance service
charts shown on the following pages.
You need this information to establish
your compliance with the servicing
and maintenance requirements of your
vehicle warranties.
Detailed warranty information is
provided in your Service Passport.
Repairs and adjustments required as
a result of improper maintenance or a
lack of required maintenance are not
covered.
Owner maintenance
precautions
Inadequate, incomplete or insufficient
servicing may result in operational
problems with your vehicle that could
lead to vehicle damage, an accident, or
personal injury. This chapter provides
instructions only for the maintenance
items that are easy to perform.
Your vehicle should not be modified
in any way. Such modifications may
adversely affect the performance, safety
or durability of your vehicle and may, in
addition, violate conditions of the limited
warranties covering the vehicle.
NOTICE
Improper owner maintenance during
the warranty period may affect
warranty coverage. For details, read
the separate Service Passport provided
with the vehicle. If you’re unsure
about any servicing or maintenance
procedure, we recommend that the
system be serviced by a HYUNDAI
authorised repairer.

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.

tyre, the rim of the wheel and the

Maintenance
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the Service
Passport in your vehicle.
Your vehicle is equipped with an
emission control system to meet all
emission regulations.
There are three emission control systems
which are as follows.
(1) Crankcase emission control system
(2) Evaporative emission control system
(3) Exhaust emission control system
In order to ensure the proper function
of the emission control systems, it is
recommended that you have your car
inspected and maintained by a HYUNDAI
authorised repairer in accordance
with the maintenance schedule in this
manual.
NOTICE
For the Inspection and Maintenance
Test (with Electronic Stability Control
(ESC) system)

[ 7RSUHYHQWWKHYHKLFOHIURPPLVILULQJ
during dynamometer testing, turn
the Electronic Stability Control
(ESC) system off by pressing the ESC
switch.

completed, turn the ESC system back
on by pressing the ESC switch again.
1. Crankcase emission control
system
The positive crankcase ventilation
system is employed to prevent air
pollution caused by blow-by gases
being emitted from the crankcase. This
system supplies fresh filtered air to the
crankcase through the air intake hose.
Inside the crankcase, the fresh air mixes
with blow-by gases, which then pass
through the PCV valve into the induction
system.
2. Evaporative emission control
system
The Evaporative Emission Control
System is designed to prevent fuel
vapours from escaping into the
atmosphere.
Canister
Fuel vapours generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapours absorbed in
the canister are drawn into the surge
tank through the purge control solenoid
valve.
Purge Control Solenoid Valve
(PCSV)
The purge control solenoid valve
is controlled by the Engine Control
Module (ECM); when the engine coolant
temperature is low during idling, the
PCSV closes so that evaporated fuel
is not taken into the engine. After
the engine warms up during ordinary
driving, the PCSV opens to introduce
evaporated fuel to the engine.
