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.

SAFETY MESSAGES
Your safety, and the safety of others, is very important. This Owner’s Manual provides you with many safety precautions and operating procedures. This information alerts you to potential hazards that may hurt you or others, as well as damage to your vehicle. Safety messages found on vehicle labels and in this manual describe these hazards and what to do to avoid or reduce the risks.
Warnings and instructions contained in this manual are for your safety. Failure to follow safety warnings and instructions can lead to serious injury or death.
This is the safety alert sym-bol. It is used to alert you to potential physical injury hazards. Obey all safety messages that follow this symbol to avoid possible injury or death. The safety alert sym-bol precedes the signal words DANGER, WARNING, and CAUTION.
DANGER
DANGER indicates a hazardous situation that, if not avoided, will result in death or serious injury.
WARNING
WARNING indicates a hazardous situation which, if not avoided, could result in death or serious injury.
Gasoline containing alcohol or methanol
Gasohol, a mixture of gasoline and ethanol (also known as grain alcohol) is being marketed along with or instead of leaded or unleaded gasoline. For example, “E15” is a gasohol comprised of 15% ethanol and 85%gasoline. Do not use gasohol containing more than 15% ethanol, and do not use gasoline or gasohol containing any methanol. Either of these fuels may cause drivability problems and damage to the fuel system, engine control system, and emission control system. Discontinue using gasohol of any kind if drivability problems occur. “E85” fuel is an alternative fuel com-prised of 85 per cent ethanol and 15 percent gasoline and is manufactured exclusively for use in Flexible Fuel Vehicles. “E85” is not compatible with your vehicle. Use of “E85” may result in poor engine performance and damage to your vehicle’s engine and fuel system. HYUNDAI recommends that customers do not use fuel with an ethanol content exceeding 15 per cent.
To prevent damage to your vehicle’s engine and fuel system:
- Never use gasohol which con-tains methanol.
- Never use gasohol containing more than 15% ethanol.
- Never use leaded fuel or leaded gasohol.
- Never use “E85” fuel.
Your New Vehicle Limited Warranty does not cover damage to the fuel system or any perform-ance problems caused by the use of “E85” fuel.
NOTICE
Damage to the fuel system or performance problem caused by the use of these fuels or fuel additives may not be covered by your New Vehicle Limited Warranty.
IMPORTANT SAFETY PRECAUTIONS
You will find many safety precautions and recommendations throughout this section, and throughout this manual. The safety precautions in this section are among the most important.
Always Wear Your Seat Belt
A seat belt is your best protection in all types of accidents. Air bags are designed to supplement seat belts, not replace them. So even though your vehicle is equipped with air bags, ALWAYS make sure you and your passengers wear your seat belts, and wear them properly.
Restrain All Children
All children under age 13 should ride in your vehicle properly restrained in a rear seat, not the front seat. Infants and small children should be restrained in an appropriate child restraint. Larger children should use a booster seat with the lap/shoulder belt until they can use the seat belt properly without a booster seat.
Air Bag Hazards
While air bags can save lives, they can also cause serious or fatal injuries to occupants who sit too close to them, or who are not prop-erly restrained. Infants, young chil-dren, and shorter adults are at the greatest risk of being injured by an inflating air bag. Follow all instruc-tions and warnings in this manual.
Driver Distraction
Driver distraction presents a serious and potentially deadly danger, espe-cially for inexperienced drivers. Safety should be the first concern when behind the wheel and drivers need to be aware of the wide array of potential distractions, such as drowsiness, reaching for objects, eating, personal grooming, other passengers, and using cellular phones.
Drivers can become distracted when they take their eyes and attention off the road or their hands off the wheel to focus on activities other than driv-ing. To reduce your risk of distraction or getting into an accident:
- ALWAYS set up your mobile devices (i.e., MP3 players, phones, navigation units, etc.) when your vehicle is parked or safely stopped.
- ONLY use your mobile device when allowed by laws and when conditions permit safe use. NEVER text or email while driving. Most states have laws prohibiting drivers from texting. Some states and cities also prohibit drivers from using handheld phones.
- NEVER let the use of a mobile device distract you from driving. You have a responsibility to your passengers and others on the road to always drive safely, with your hands on the wheel as well as your eyes and attention on the road.
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 tire blowout or a mechanical failure can be extremely hazardous. To reduce the possibility of such problems, check your tire pres-sures and condition frequently, and perform all regularly scheduled maintenance.
