Using Fuel Additives (except Detergent Fuel Additives)
Using fuel additives such as: - Silicone fuel additive
- Ferrocene (iron-based) fuel additive
- Other metallic-based fuel additives
may result in cylinder misfire, poor acceleration, engine stalling, damage to the
catalyst, or abnormal corrosion, and may cause damage to the engine resulting in a
reduction in the overall life of the powertrain.
- The Malfunction Indicator Lamp (MIL) may illuminate.
NOTICE
Damage to the fuel system or performance problem caused by the use of these fuels
may not be covered by your New Vehicle Limited Warranty.
Gasoline containing MMT
Some gasoline contains harmful manganese-based fuel additives such as MMT
(Methylcyclopentadienyl Manganese Tricarbonyl). HYUNDAI does not recommend the
use of gasoline containing MMT. This type of fuel can reduce vehicle performance and
affect your emission control system.
The malfunction indicator lamp on the cluster may come on.
Detergent Fuel Additives
HYUNDAI recommends that you use good quality gasolines treated with detergent
additives such as TOP TIER Detergent Gasoline, which help prevent deposit formation
in the engine. These gasolines will help the engine run cleaner and enha\
nce
performance of the Emission Control System. For more information on TOP TIER
Detergent Gasoline, please go to the website (www. toptiergas.com).
For customers who do not use TOP Tier Detergent Gasoline regularly, and have
problems starting or the engine does not run smoothly, detergent-based fuel additives
that you can purchase separately may be added to the gasoline. If TOP TIER Detergent
Gasoline is not available, one bottle of additive added to the fuel tank according to the
maintenance schedule is recommended (refer to the Maintenance Schedule in chapter
9).
Additives are available from your authorized HYUNDAI dealer along with information
on how to use them. Do not mix other additives.
Operation in foreign countries
If you are going to drive your vehicle in another country, be sure to:
• Observe all regulations regarding registration and insurance.
• Determine that acceptable fuel is available.

VEHICLE MODIFICATIONS
• This vehicle should not be modified. Modification of your vehicle could affect its performance, safety or durability and may even violate governmental safety and
emissions regulations.
In addition, damage or performance problems resulting from any modification may
not be covered under warranty.
• If you use unauthorized electronic devices, it may cause the vehicle to operate abnormally, wire damage, battery discharge and fire. For your safety, do not use
unauthorized electronic devices.
NOTICE
Some warning sounds (including welcome/good-bye sound, etc.) are generated
from the interior speakers or amplifiers. If necessary, purchase HYUNDAI Part to
replace an interior speaker or amplifier. Any unauthorized product may cause a
malfunction of the interior speakers or amplifiers.
VEHICLE BREAK-IN PROCESS
By following a few simple precautions for the first 600 miles (1,000 km) you may add to
the performance, economy and life of your vehicle.
• Do not race the engine.
• While driving, avoid sudden acceleration.
• Do not maintain a single speed for long periods of time, either fast or slow. Varying engine speed is needed to properly break-in the engine.
• Avoid hard stops, except in emergencies, to allow the brakes to seat properly.
• Fuel economy and engine performance may vary depending on vehicle break-in process and be stabilized after 4,000 miles (6,000 km). New engines may consume
more oil during the vehicle break-in period.
• Do not tow a trailer during the first 1,200 miles (2,000km) of operation.
WARNING
CALIFORNIA PROPOSITION 65 WARNING
Items contained in motor vehicles or emitted from them are known to the State of
California to cause cancer and birth defects or reproductive harm. These include:
• Gasoline and its vapors
• Engine exhaust
• Used engine oil
• Interior passenger compartment components and materials
• Component parts which are subject to heat and wear
In addition, battery posts, terminals and related accessories contain lead, lead
compounds and other chemicals known to the State of California to cause cancer
and reproductive harm.

VEHICLE DATA COLLECTION AND EVENT DATA RECORDERS
This vehicle is equipped with an event data recorder (EDR). The main purpose of
an EDR is to record, in certain crash or near crash-like situations, such as an air bag
deployment or hitting a road obstacle, data that will assist in understanding how a
vehicle’s systems performed. The EDR is designed to record data related to vehicle
dynamics and safety systems for a short period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to record such data as:
• How various systems in your vehicle were operating;
• Whether or not the driver and passenger safety belts were buckled/fastened;
• How far (if at all) the driver was depressing the accelerator and/or brake pedal; and,
• How fast the vehicle was traveling.
These data can help provide a better understanding of the circumstances in which
crashes and injuries occur. NOTE: EDR data are recorded by your vehicle only if a non-
trivial crash situation occurs; no data are recorded by the EDR under normal driving
conditions and no personal data (for example, name, gender, age, and crash location)
are recorded. However, other parties, such as law enforcement, could combine the
EDR data with the type of personally identifying data routinely acquired during a crash
investigation.
To read data recorded by an EDR, special equipment is required, and access to the
vehicle or the EDR is needed. In addition to the vehicle manufacturer, other parties,
such as law enforcement, that have the special equipment, can read the information if
they have access to the vehicle or the EDR.

HEV (HYBRID ELECTRIC VEHICLE) SYSTEM
The HYUNDAI Hybrid Electric Vehicle (HEV) uses both the gasoline engine and the
electric motor for power. The electric motor is run by a high-voltage HEV battery.
Depending on the driving conditions, the HEV computer selectively operates between
the engine and the electric motor or even both at the same time.
Fuel efficiency increases when the engine is at idle, or when the vehicle is driven by the
electric motor with the HEV battery.
The HEV battery charge must be maintained, so at times the engine will come on even
at idle to act as a generator. Charging also occurs when decelerating or by regenerative
braking.

Foreword/Starting your Hybrid/Plug-in hybrid vehicle1-10
The HYUNDAI Plug-in Hybrid Electric Vehicle (PHEV) shares the characteristics of both
a conventional hybrid electric vehicle and an all-electric vehicle.
When used as a conventional hybrid electric vehicle, the HEV computer selectively
operates between the engine and the electric motor or even both at the same time.
When it is operating in the electric vehicle mode, the vehicle is driven only using
the electric motor over a certain distance until the hybrid battery becomes low. The
driving distance in EV mode depends on customer driving style and road conditions.
Aggressive driving maneuvers or in need of diagnosis for emission related parts, may
enable the engine to operate. However, engine power can be limited during emission
reduction control period in cold engine condition.
The hybrid battery can be fully charged by connecting a plug to an external electric
power source.

Scheduled Charging
(if equipped)
• You can set-up a charging schedule for your vehicle using the
infotainment system or BlueLink
application.
Refer to the infotainment system
manual or the BlueLink manual for
detailed information about setting
scheduled charging.
• Scheduled charging can only be done when using a AC charger or
the portable charger (ICCB: InCable
Control Box).
ONX4EPHQ011020LONX4EPHQ011020L
• When scheduled charging is set and the AC charger or the portable
charger (ICCB: In-Cable Control
Box) is connected for charging, the
indicator lamp in the middle blinks (for
3 minutes) to indicate that scheduled
charging is set.
• When scheduled charging is set, charging is not initiated immediately
when the AC charger or portable
charger (ICCB: In-Cable Control
Box) is connected. When immediate
charging is required, use the
infotainment system to deactivate
the scheduled charge setting or press
scheduled charging deactivation (
)
button.
ONX4EPHQ011021LONX4EPHQ011021L
• If you press the scheduled charging deactivation () button
to immediately charge the battery,
charging must be initiated 3 minutes
after the charging cable has been
connected. When you press the
scheduled charging deactivation
(
) button for immediate charging,
the scheduled charge setting is not
completely deactivated. If you need to
completely deactivate the scheduled
