NOTICE
• It is permissible to add 20 kPa (3 psi) to the standard tire pressure specification if
colder temperatures are expected soon. Tires typically lose 7 kPa (1 psi) for every
7°C (12°F) temperature drop. If extreme temperature variations are expected,
recheck your tire pressure as necessary to keep them properly inflated.
• An air pressure generally decreases, as you drive up to a high-altitude area above
sea level. Thus, if you plan to drive a high-altitude area, check the tire pressures
in advance. If necessary, inflate them to a proper level (Air inflation per altitude:
+10 kPa/1 km (+2.4 psi/1 mile).
• Spare wheel are intended for emergency purpose.
• Only Steel wheel is provided as spare wheel. Spare tires can be from any
manuafacturer.
CAUTION
When replacing tires, always use tires of the same type, size, brand, construction
and tread pattern.
Using tires of a different size can damage the related parts or make it work
irregularly.

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.

2 : Requires grade engine oil. If a lower grade engine oil (mineral oil
including Semi-synthetic other than API SN plus) is used, then the engine oil and engine oil
filter must be replaced as indicated severe maintenance condition.
*
3 : Use only specified genuine Intelligent Variable Transmission fluid. The use of non-specified
fluid (even marked as compatible with genuine) could result in shift quality deterioration and
vibrations, eventually, the transmission failure.
*
4 :We recommend that you use the engine oils approved by HYUNDAI Motor India Ltd. We
recommend that you consult an authorized HYUNDAI dealer for details.

Vehicle information
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.

CAUTION
Always be sure to clean the area around any filler plug, drain plug, or dipstick
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.
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.
