Introduction
FOREWORD
Congratulations, and thank you for choosing HYUNDAI. We are pleased to welcome
you to the growing number of discerning people who drive HYUNDAIs.We are very
proud of the advanced engineering and high-quality construction of each HYUNDAI
we build.
Your Owner’s Manual will introduce you to the features and operation of your new
HYUNDAI. To become familiar with your new HYUNDAI, so that you can fully enjoy it,
read this Owner’s Manual carefully before driving your new vehicle.
This manual contains important safety information and instructions intended to
familiarize you with your vehicle’s controls and safety features so you can safely
operate your vehicle.
This manual also contains information on maintenance designed to enhance safe
operation of the vehicle. It is recommended that all service and maintenance on your
car be performed by a HYUNDAI authorised repairer. HYUNDAI dealers are prepared
to provide high-quality service, maintenance and any other assistance that may be
required.
This Owner’s Manual should be considered a permanent part of your vehicle, and
should be kept in the vehicle so you can refer to it at any time. The manual should
stay with the vehicle if you sell it to provide the next owner with important operating,
safety and maintenance information.
HYUNDAI MOTOR COMPANY
CAUTIONSevere engine and transmission damage may result from the use of poor quality
fuels and lubricants that do not meet HYUNDAI specifications. You must always use
high quality fuels and lubricants that meet the specifications listed on Page 2-14 in
the Vehicle Specifications section of the Owner’s Manual.

01
Use of MTBE
HYUNDAI recommends avoiding fuels containing MTBE (Methyl Tertiary Butyl Ether)
over 15.0% vol. (Oxygen Content 2.7% weight) in your vehicle.
Fuel containing MTBE over 15.0% vol. (Oxygen Content 2.7% weight) may reduce
vehicle performance and produce vapour lock or hard starting.
CAUTION
Your New Vehicle Limited Warranty may not cover damage to the fuel system and
any performance problems that are caused by the use of fuels containing methanol
or fuels containing MTBE (Methyl Tertiary Butyl Ether) over 15.0% vol. (Oxygen
Content 2.7% weight.)
Do not use methanol
Fuels containing methanol (wood alcohol) should not be used in your vehicle. This
type of fuel can reduce vehicle performance and damage components of the fuel
system, engine control system and emission control system.
Fuel Additives
HYUNDAI recommends that you use unleaded petrol which has an octane rating of
RON (Research Octane Number) 95 / AKI (Anti Knock Index) 91 or higher (for Europe)
or Octane Rating of RON (Research Octane Number) 91 / AKI (Anti-Knock Index) 87 or
higher (except Europe).
For customers who do not use good quality petrols including fuel additives
regularly, and have problems starting or the engine does not run smoothly, one
bottle of additive added to the fuel tank according to the maintenance schedule is
recommended.
Additives are available from your HYUNDAI authorised repairer along with information
on how to use them. Do not mix other additives.
Operation in foreign countries

RECOMMENDED LUBRICANTS AND CAPACITIES
To help achieve proper engine and powertrain performance and durability, use only
lubricants of the proper quality. The correct lubricants also help promote engine
efficiency that results in improved fuel economy.
These lubricants and fluids are recommended for use in your vehicle.

before checking or draining any lubricant. This is especially important in dusty or
sandy areas and when the vehicle is used on unpaved roads. Cleaning the plug
and dipstick areas will prevent dirt and grit from entering the engine and other
mechanisms that could be damaged.
Engine oil viscosity (thickness) has an effect on fuel economy and cold weather
operating (engine start and engine oil flowability). Lower viscosity engine oils can
provide better fuel economy and cold weather performance, however, higher
viscosity engine oils are required for satisfactory lubrication in hot weather. Using oils
of any viscosity other than those recommended could result in engine damage.
When choosing an oil, consider the range of temperature your vehicle will be
operated in before the next oil change.
Proceed to select the recommended oil viscosity from the chart.

An engine oil displaying this American Petroleum Institute(API)
Certification Mark conforms to the International Lubricant
Specification Advisory Committee (ILSAC). It is recommended
to only use engine oils that uphold this API Certification Mark.

Control your speed
Excessive speed is a major factor in
crash injuries and deaths. Generally, the
higher the speed, the greater the risk,
but serious injuries can also occur at
lower speeds. Never drive faster than is
safe for current conditions, regardless of
the maximum speed posted.
Keep your vehicle in safe
condition
Having a tyre blowout or a mechanical
failure can be extremely hazardous. To
reduce the possibility of such problems,
check your tyre pressures and condition
frequently, and perform all regularly
scheduled maintenance.

Safety system
Do not install a Child Restraint
System on the front passenger
seat
OHI038169L
Never install a Child Restraint System in
the front passenger’s seat. An inflating air
bag can forcefully strike a child or restraint
resulting in serious or fatal injury.
WARNING

[Extreme hazard! Do not use a
rearward facing Child Restraint
System on a seat protected by an air
bag in front of it!

[NEVER use a rearward facing Child
Restraint System on a seat protected
by an ACTIVE AIRBAG in front of it,
DEATH or SERIOUS INJURY to the
CHILD can occur.

[Never put a Child Restraint System in
the front passenger’s seat. If the front
passenger air bag inflates, it would
cause serious or fatal injuries.
Why didn’t my air bag go off in a
collision?
There are certain types of accidents in
which the air bag would not be expected
to provide additional protection. These
include rear impacts, second or third
collisions in multiple impact accidents,
as well as low speed impacts. Damage to
the vehicle indicates a collision energy
absorption, and is not an indicator of
whether or not an air bag should have
inflated.
Air bag collision sensors
WARNING
To reduce the risk of an air bag
deploying unexpectedly and causing
serious injury or death:

[Do not hit or allow any objects to
impact the locations where air bags
or sensors are installed.

[Do not perform maintenance on or
around the air bag sensors. If the
location or angle of the sensors is
altered, the air bags may deploy
when they should not or may not
deploy when they should.

[Installing bumper guards with non-
genuine Hyundai or non-equivalent
parts may adversely affect the
collision and airbag deployment
performance.
To ensure correct function of the
airbag system we recommend to
replace the bumper with genuine
HYUNDAI part or the equivalent (of
the genuine part) specified for your
vehicle.

[Place the ignition switch to the
LOCK/OFF or ACC position, when the
vehicle is being towed to prevent
inadvertent air bag deployment.

[We recommend that all air bag
repairs are conducted by a HYUNDAI
authorised repairer.
