Petrol engine  
Unleaded  
For the optimal vehicle performance, we recommend you use unleaded petrol which  
has an octane rating of RON (Research Octane Number) 95 / AKI (Anti Knock Index)  
91 or higher. You may use unleaded petrol with an octane rating of RON 91-94 / AKI  
87-90 but it may result in slight performance reduction of the vehicle. (Do not use  
methanol blended fuels)  
Your new vehicle is designed to obtain maximum performance with UNLEADED FUEL,  
as well as minimise exhaust emissions and spark plug fouling.  
CAUTION  
NEVER USE LEADED FUEL. The use of leaded fuel is detrimental to the catalytic  
converter and will damage the engine control system’s oxygen sensor and affect  
emission control.  
Never add any fuel system cleaning agents to the fuel tank other than what has  
been specified (We recommend that you consult a HYUNDAI authorised repairer for  
details.)  
WARNING  
śꢀ Do not “top off” after the nozzle automatically shuts off when refuelling.  
śꢀ Always check that the fuel cap is installed securely to prevent fuel spillage in the  
event of an accident.  
Introduction  
Leaded (if equipped)  
For some countries, your vehicle is designed to use leaded petrol. When you are going  
to use leaded petrol, we recommend that you ask a HYUNDAI authorised repairer.  
Octane rating of leaded petrol is same with unleaded one.  
Petrol containing alcohol and methanol  
Gasohol, a mixture of petrol and ethanol (also known as grain alcohol), and petrol or  
gasohol containing methanol (also known as wood alcohol) are being marketed along  
with or instead of leaded or unleaded petrol.  
Do not use gasohol containing more than 10% ethanol, and do not use petrol 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.  
Vehicle damage or driveability problems may not be covered by the manufacturer’s  
warranty if they result from the use of:  
1. Gasohol containing more than 10% ethanol.  
2. Petrol or gasohol containing methanol.  
3. Leaded fuel or leaded gasohol.  
CAUTION  
Never use gasohol which contains methanol. Discontinue use of any gasohol  
product which impairs drivability.  
Other fuels  
Using fuel additives such as:  
- Silicone fuel additive  
- MMT (Magnanese, Mn) 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.  
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.  
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.
