Maintenance
Do not use strong soap, chemi-cal 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 interi-
or.
To prevent damage to the plastic parts, do not clean with chemi-
cal solvents or strong deter-
gents. Water washing in the fuel cell
power module compartment
including high pressure water
washing may cause the failure
of electrical circuits located in
the fuel cell power module com-
partment.
Never allow water or other liquids to come in contact with electri-
cal/electronic components inside
the vehicle as this may damage
them. Matte paint finish vehicle
Automatic car wash which uses
rotating brushes should not be
used as this can damage the sur-
face of your vehicle. A steam
cleaner which washes the vehicle
surface at high temperature may
result the oil to adhere and leave
stains that is difficult to remove.
Use a soft cloth (e.g. microfiber
towel or sponge) when washing
your vehicle and dry with a
microfiber towel. When you hand
wash your vehicle, you should not
use a cleaner that finishes with
wax. If the vehicle surface is too
dirty (sand, dirt, dust, contami-
nant, etc.), clean the surface with
water before washing the car.

Maintenance
Waxing
A good coat of wax provides a barri-
er between your paint and environ-
mental contamination.
Keeping a good coat of wax on your
vehicle will help protect it.
Wax the vehicle when water will no
longer bead on the paint.
Always wash and dry the vehicle
before waxing. Use a good quality
liquid or paste wax, and follow the
manufacturer’s instructions. Wax all
metal trim to protect it and to main-
tain its luster.
Removing oil, tar, and similar materi-
als with a spot remover will usually
strip the wax from the finish. Be sure
to re-wax these areas even if the rest
of the vehicle does not yet need wax-
ing. Wiping dust or dirt off the body
with a dry cloth will scratch the
finish.
Do not use steel wool, abrasive cleaners, or strong detergents
containing highly alkaline or
caustic agents on chrome-plat-
ed or anodized aluminum parts.
This may result in damage to the
protective coating and cause
discoloration or paint deteriora-
tion.
Matte paint finish vehicle
Do not use any polish protector
such as a detergent, an abrasive
and a polish. In case wax is
applied, remove the wax immedi-
ately using a silicon remover and
if any tar or tar contaminant is on
the surface use a tar remover to
clean. However, be careful not to
apply too much pressure on the
painted area.
Repairing your vehicle’s finish
Deep scratches or stone chips in the
painted surface must be repaired
promptly. Exposed metal will quickly
rust and may develop into a major
repair expense.
If your vehicle is damaged and
requires any metal repair or
replacement, be sure the body
shop applies anti-corrosion mate-
rials to the parts repaired or
replaced.
Matte paint finish vehicle
In case of matte paint finish vehi-
cles, it is impossible to modify
only the damaged area and repair
of the whole part is necessary. If
the vehicle is damaged and paint-
ing is required, we recommend
that you have your vehicle main-
tained and repaired by an author-
ized HYUNDAI dealer. Take
extreme care, as it is difficult to
restore the quality after the repair.

Maintenance
vehicle, pay particular attention to
the components under the fenders
and other areas that are hidden
from view. Do a thorough job; just
dampening the accumulated mud
rather than washing it away will
accelerate corrosion rather than
prevent it. Water under high pres-
sure and steam are particularly
effective in removing accumulated
mud and corrosive materials.
When cleaning lower door panels, rocker panels and frame members,
be sure that drain holes are kept
open so that moisture can escape
and not be trapped inside to accel-
erate corrosion.Keep your garage dry
Don’t park your car in a damp, poor-
ly ventilated garage. This creates a
favorable environment for corrosion.
This is particularly true if you wash
your vehicle in the garage or drive it
into the garage when it is still wet or
covered with snow, ice or mud. Even
a heated garage can contribute to
corrosion unless it is well ventilated
so moisture is dispersed.
Keep paint and trim in good condition
Scratches or chips in the finish
should be covered with "touch-up"
paint as soon as possible to reduce
the possibility of corrosion. If bare
metal is showing through, the atten-
tion of a qualified body and paint
shop is recommended.
Bird droppings are highly corrosive
and may damage painted surfaces in
just a few hours. Always remove bird
droppings as soon as possible.
Interior Care
Interior general precautions
Prevent caustic solutions such as
perfume and cosmetic oil, from con-
tacting the interior parts because
they may cause damage or discol-
oration. If they do contact the interior
parts, wipe them off immediately.
See the instructions for the proper
way to clean vinyl.
Never allow water or other liq-uids to come in contact with
electrical/electronic compo-
nents inside the vehicle as this
may damage them.
When cleaning leather products (steering wheel, seats etc.), use
neutral detergents or low alco-
hol content solutions. If you use
high alcohol content solutions
or acid/alkaline detergents, the
color of the leather may fade or
the surface may get stripped off.

Maintenance
Caring for the leather seats- Vacuum the seat periodically toremove dust and sand on the
seat. It will prevent abrasion or
damage of the leather and main-
tain its quality.
- Wipe the natural leather seat cover often with dry or soft cloth.
- Use of proper leather protective may prevent abrasion of the
cover and helps maintain the
color. Be sure to read the instruc-
tions and consult a specialist
when using leather coating or
protective agent.
- Light colored (beige, cream beige) leather is easily contami-
nated and the stain is noticeable.
Clean the seats frequently.
- Avoid wiping with wet cloth. It may cause the surface to crack. Cleaning the leather seats
- Remove all contaminationsinstantly. Refer to instructions
below for removal of each con-
taminant.
- Cosmetic products (sunscreen, foundation, etc.)
Apply cleansing cream on a cloth
and wipe the contaminate spot.
Wipe off the cream with a wet
cloth and remove water with a dry
cloth.
- Beverages (coffee, soft drink, etc.)
Apply a small amount of neutral
detergent and wipe until contami-
nations do not smear.
- Oil Remove oil instantly with
absorbable cloth and wipe with
stain remover used only for natu-
ral leather.
- Chewing gum Harden the gum with ice and
remove gradually.Cleaning the seat belt webbing
Clean the belt webbing with any mild
soap solution recommended for
cleaning upholstery or carpet. Follow
the instructions provided with the
soap. Do not bleach or re-dye the
webbing because this may weaken
the seat belt.
Cleaning the interior windowglass
If the interior glass surfaces of the
vehicle become fogged (that is, cov-
ered with an oily, greasy or waxy
film), they should be cleaned with
glass cleaner. Follow the directions
on the glass cleaner container.
Do not scrape or scratch the
inside of the rear window. This
may result in damage to the rear
window defroster grid.

Hydrogen
System
(7 items)
37. Is it possible that water, oil, etc. may be
introduced to the hydrogen gas tank via
the fuel filler? If yes, what do I need to
do to prevent this?Normally, water and oil cannot flow into the hydrogen tank via the
fuel filler, but it can flow in while refueling. Be careful not to intro-
duce any contaminants via the fuel filler.
38. While refueling the hydrogen, I hear
irregular abnormal noises. Is this noise
cause for concern?
The hydrogen gas is in high pressure (70 MPa) condition when refu-
eled to the vehicle's storage tank. Therefore, you will hear the sound
of the gas flowing in the beginning. Abnormal noise is occurred due
to the gas flow because of the difference in refueling pressure, etc.
depending on the gas pressure condition at the refueling station and
this is very normal.
