Exterior care
Exterior general caution
It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning and
caution statements that appear on the
label.
Finish maintenance
Washing
To help protect your vehicle’s finish from
rust and deterioration, wash it thoroughly
and 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 kept
clear 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 do
not wash the vehicle in direct
sunlight or when the body of the
vehicle is warm.
• Be careful when washing the side
windows of your vehicle.
Especially, with high-pressure
water, water may leak through the
windows and wet the interior.
• To prevent damage to the plastic
parts and lamps, do not clean
with chemical solvents 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 engine
and related part located in the
engine compartment.
• Never allow water or other liquids
to come in contact with electri-
cal/electronic components and
air duct inside the vehicle as this
may damage them.

Maintenance
EMISSION CONTROL SYSTEM (IF EQUIPPED)
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.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 valve
into the induction system.
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
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.
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 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.
When choosing an oil, consider the range of temperature your vehicle will be operat-
ed in before the next oil change. Proceed to select the recommended oil viscosity from
the chart.
