Bright-metal maintenance
[ To remove road tar and insects, use
a tar remover, not a scraper or other
sharp object.
[ To protect the surfaces of bright metal
parts from corrosion, apply a coating
of wax or chrome preservative and rub
to a high luster.
[ During winter weather or in coastal
areas, cover the bright metal parts
with a heavier coating of wax or
preservative. If necessary, coat the
parts with non-corrosive petroleum
jelly or other protective compound.
Underbody maintenance
Corrosive materials used for ice and
snow removal and dust control may
collect on the underbody. If these
materials are not removed, accelerated
rusting can occur on underbody parts
such as the fuel lines, frame, floor pan
and exhaust system, even though they
have been treated with rust protection.
Thoroughly flush the vehicle underbody
and wheel openings with lukewarm or
cold water once a month, after off-road
driving and at the end of each winter. Pay
special attention to these areas because
it is difficult to see all the mud and dirt.
It will do more harm than good to wet
down the road grime without removing
it. The lower edges of doors, rocker
panels, and frame members have drain
holes that should not be allowed to clog
with dirt; trapped water in these areas
can cause rusting.
WARNING
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 forward
speed.
Aluminum wheel maintenance
The aluminum wheels are coated with a
clear protective finish.
[ Do not use abrasive cleaner, polishing
compound, solvent, or wire brushes
on aluminum wheels.
[ Clean the wheel when it has cooled.
[ Use only a mild soap or neutral
detergent, and rinse thoroughly with
water. Also, clean the wheels after
driving on salted roads.
[ Do not wash the wheels with high-
speed car wash brushes.
[ Do not use any cleaners containing
acid or alkaline detergents.

Your vehicle is equipped with a catalytic
converter emission control device.
To prevent damage to the catalytic
converter and to your vehicle, take the
following precautions:
[ Use only UNLEADED FUEL for
gasoline engines.
[ Do not operate the vehicle when
there are signs of engine malfunction,
such as misfire or a noticeable loss of
performance.
[ Do not misuse or abuse the engine.
Examples of misuse are coasting with
the engine off and descending steep
grades in gear with the engine off.
[ Do not operate the engine at high
idle speed for extended periods (5
minutes or more).
[ Do not modify or tamper with any
part of the engine or emission
control system. Have all inspections
and adjustments are made by an
authorized HYUNDAI dealer.
[ Avoid driving with an extremely low
fuel level.
Running out of fuel could cause the
engine to misfire, damaging the
catalytic converter.Gasoline Particulate Filter (GPF)
(if equipped)
Gasoline Particulate Filter (GPF) system
removes the soot in the exhaust gas.
The GPF system automatically burns
(or oxidizes) the accumulated soot in
accordance with driving situations,
unlike a disposable air filter.
In other words, the accumulated soot is
automatically purged out by the engine
control system and by the high exhaust-
gas temperature at normal/ high driving
speeds. However, when the vehicle is
continually driven at repeated short
distances or driven at low speed for a
long time, the accumulated soot may
not be automatically removed because
of low exhaust gas temperature. In this
case, the accumulated soot may reach
a certain amount regardless of the soot
oxidization process, then the GPF lamp
(
) will illuminate.
The Gasoline Particulate Filter (GPF)
lamp stops illuminating, when the
driving speed exceeds 50 mph (80 km/h)
with engine rpm 1,500 ~ 4,000 and the
gear in the 3rd position or above for
approximately 30 minutes.
When the GPF lamp starts to blink or
the warning message “Check exhaust
system” pops up even though the vehicle
was driven as mentioned above, have the
GPF system checked by an authorized
HYUNDAI dealer.
With GPF lamp blinking for an extended
period of time, it may damage the GPF
system and lower the fuel economy.
CAUTION
We recommend you to use only the
regulated gasoline fuels, when your
vehicle is equipped with the GPF
system.
When you use other gasoline fuels
which contain unspecified additives,
they may damage the GPF system and
cause exhaust emission problems.
