Finish maintenance
Washing
To help protect your vehicle’s finish from
rust and deterioration, wash it thoroughlyand frequently at least once a month with
lukewarm or cold water.
If you use your vehicle for off-road driv-
ing, you should wash it after each off-
road trip. Pay special attention to the
removal of any accumulation of salt, dirt,
mud, and other foreign materials. Make
sure the drain holes in the lower edges of
the doors and rocker panels are keptclear and clean.
Insects, tar, tree sap, bird droppings,
industrial pollution and similar deposits
can damage your vehicle’s finish if not
removed immediately.
Even prompt washing with plain water
may not completely remove all these
deposits. A mild soap, safe for use on
painted surfaces, may be used. After washing, rinse the vehicle thor-
oughly with lukewarm or cold water. Do
not allow soap to dry on the finish.
APPEARANCE CARE
CAUTION
Do not use strong soap, chemical
detergents or hot water, and donot wash the vehicle in direct
sunlight or when the body of thevehicle is warm.
Be careful when the side win- dows of your vehicle. Especailly,with high-pressure water. Water
may leak through the windowsand wet the interior.
To prevent damage to the plastic parts, do not clean with chemicalsolvents or strong detergents.
WARNING - Wet brakes
After washing the vehicle, test the
brakes while driving slowly to see if
they have been affected by water. If
braking performance is impaired,
dry the brakes by applying them
lightly while maintaining a slow for-
ward speed.
CAUTION
Water washing in the engine com- partment including high pressure
water washing may cause the fail-ure of electrical circuits or engineand related part located in the engine compartment.
Never allow water or other liquids to come in contact with electri-cal/electronic components inside the vehicle as this may damage
them.

EMISSION CONTROL SYSTEM (IF EQUIPPED)
G270000AEN
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty infor-
mation contained in the Service Passport
in your vehicle.
Your vehicle is equipped with an emis-
sion control system to meet all applicable
emission regulations. There are three emission control sys-
tems, as follows.
(1) Crankcase emission control system
(2) Evaporative emission control system(3) Exhaust emission control system In order to assure the proper function of
the emission control systems, it is rec-
ommended that you have your car
inspected and maintained by an author-
ized HYUNDAI dealer in accordance with
the maintenance schedule in this manu-al. Caution for the Inspection and
Maintenance Test (With Electronic
Stability Program (ESP) system)
To prevent the vehicle from misfir-
ing during dynamometer testing,
turn the Electronic Stability
Program (ESP) system off by press-
ing the ESP switch.
After dynamometer testing is com- pleted, turn the ESP system back on
by pressing the ESP switch again. G270100AUN
1. Crankcase emission control
system
The positive crankcase ventilation sys-
tem is employed to prevent air pollution
caused by blow-by gases being emitted
from the crankcase. This system supplies
fresh filtered air to the crankcase through
the air intake hose. Inside the crankcase,
the fresh air mixes with blow-by gases,
which then pass through the PCV valveinto the induction system.
G270200AUN
2. Evaporative emission control system
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere.

Specifications & Consumer information
I040100AUN Recommended SAE viscosity
number 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 sat-
isfactory lubrication in hot weather. Using
oils of any viscosity other than those rec-ommended could result in engine dam-
age.When choosing an oil, consider the range
of temperature your vehicle will be oper-
ated 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 drain-ing any lubricant. This is especiallyimportant in dusty or sandy areas
and when the vehicle is used on unpaved roads. Cleaning the plugand dipstick areas will prevent dirt and grit from entering the engine and other mechanisms that could
be damaged.

(API SM / ILSAC GF-4). However, if the engine oil is not available in your country, select
the proper engine oil using the engine oil viscosity chart.
