Change to "winter weight" oil if
necessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
section 8 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
retailer of Genesis Branded prod-
ucts.
Check spark plugs and ignition
system
Inspect your spark plugs as
described in section 7 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked, worn or
damaged in any way.
To keep locks from freezing
To keep the locks from freezing,
squirt an approved de-icer fluid or
glycerine into the key opening. If a
lock is covered with ice, squirt it with
an approved de-icing fluid to remove
the ice. If the lock is frozen internally,
you may be able to thaw it out by
using a heated key. Handle the heat-
ed key with care to avoid injury.
Use approved window washer
anti-freeze in system
To keep the water in the window
washer system from freezing, add an
approved window washer anti-freeze
solution in accordance with instruc-
tions on the container. Window wash-
er anti-freeze is available from an
authorized retailer of Genesis
Branded products and most auto
parts outlets. Do not use engine
coolant or other types of anti-freeze
as these may damage the paint fin-
ish.
Don't let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to happen
when there is an accumulation of
snow or ice around or near the rear
brakes or if the brakes are wet. If
there is a risk of the parking brake
may freezing, apply it only temporar-
ily while you put the shift lever in P
(automatic transaxle) or in first or
reverse gear (manual transaxle) and
block the rear wheels so the vehicle
cannot roll. Then release the parking
brake.
Don't let ice and snow accumu-
late underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in severe winter conditions
where this may happen, you should
periodically check underneath the
car to be sure the movement of the
front wheels and the steering com-
ponents is not obstructed.

Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the car
is being driven in severe conditions,
more frequent oil and filter changes
are required.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary.
Fuel filter
A clogged filter can limit the speed at
which the vehicle may be driven,
damage the emission system and
cause multiple issues such as hard
starting. If an excessive amount of
foreign matter accumulates in the
fuel tank, the filter may require
replacement more frequently. After
installing a new filter, run the engine
for several minutes, and check for
leaks at the connections. Fuel filters
should be installed by an authorized
retailer of Genesis Branded prod-
ucts.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. Have an authorized retailer of
Genesis Branded products replace
any damaged or leaking parts imme-
diately.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure a new vapor
hose or fuel filler cap is correctly
replaced.
Air cleaner filter
A Genesis/Hyundai Part air cleaner
filter is recommended when the filter
is replaced.
Spark plugs
Make sure to install new spark plugs
of the correct part number and heat
range.

NOTICE
Use only the specified brake fluid
(refer to "Recommended
Lubricants and Capacities" in chap-
ter 8).
Do not allow brake fluid to
contact the vehicle’s body
paint, as paint damage will
result.
Brake fluid, which has been
exposed to open air for an
extended time should NEVER
be used as its quality cannot
be guaranteed. It should be
disposed of properly.
Do not use the wrong kind of
brake fluid. A few drops of
mineral based oil, such as
engine oil, in your brake sys-
tem can damage brake sys-
tem parts.

Do not drive with the air clean-
er filter removed. This will
result in excessive engine
wear.
When removing the air clean-
er filter, be careful that dust or
dirt does not enter the air
intake, or damage may result.
Use a Genesis/Hyundai Part,
use of non-Genesis/Hyundai
Part could damage the air flow
sensor.

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 prod-
ucts (steering wheel, seats
etc.), use neutral detergents
or low alcohol content solu-
tions. 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.
CAUTION
