Driving your vehicle
Check battery and cables
Winter temperatures affect battery
performance. Inspect the battery
and cables, as specified in the
chapter 7. The battery charging level
can be checked by a HYUNDAI
authorised repairer or in a service
station.
Change to "winter weight" oil if
necessary
In some regions during winter, it is
recommended to use the "winter
weight" oil with lower viscosity. For
further information, refer to the chap-
ter 8. When you are not sure about a
type of winter weight oil, we recom-
mend that you consult a HYUNDAI
authorised repairer. Check spark plugs and ignition
system
Inspect the spark plugs, as speci-
fied in the chapter 7.
If necessary,
replace them. Also check all ignition
wirings and components for any
cracks, wear-out, and damage.
To prevent locks from freezing
To prevent the locks from being
frozen, spray approved de-icing fluid
or glycerin into key holes. When a
lock opening is already covered with
ice, spray approved de-icing fluid
over the ice to remove it. When an
internal part of a lock freezes, try to
thaw it with a heated key. Carefully
use the heated key to avoid an injury. Use approved window washer
anti-freeze solution in system
To prevent the window washer from
being frozen, add authorised window
washer anti-freeze solution, as spec-
ified on the window washer contain-
er. Window washer anti-freeze solu-
tion is available from a HYUNDAI
authorised repairer, and most vehicle
accessory outlets. Do not use engine
coolant or other types of anti-freeze
solution, to prevent any damage to
the vehicle paint.

Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the
vehicle is being driven in severe con-
ditions, more frequent oil and filter
changes are required.
HSG (Hybrid starter & genera-
tor) belt
The HSG belt should be changed at
the intervals specified in the mainte-
nance schedule.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. We recommend a HYUNDAI
authorised repairer replace any dam-
aged or leaking parts immediately.
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 a HYUNDAI
authorised repairer.
Vapour hose and fuel filler cap
The vapour hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure a new vapour
hose or fuel filler cap is correctly
replaced.
Air cleaner filter
A genuine HYUNDAI air cleaner filter
is recommended when the filter is
replaced.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Cooling system
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Engine coolant/inverter
coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.

Maintenance
Use only the specified engine oil
(Refer to “Recommended Lubricants
and Capacities” in chapter 8).
Checking the engine oil and
filter
We recommend that the engine oil
and filter be changed by a HYUNDAI
authorised repairer according to the
Maintenance Schedule.

Maintenance
If the level is low, add the specified
brake fluid to the MAX level. The level
will fall with accumulated mileage.
This is a normal condition associated
with the wear of the brake linings. If
the fluid level is excessively low, we
recommend that the brake system
be checked by a HYUNDAI autho-
rised repairer. Do not allow brake fluid to con-
tact 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 dis-
posed of properly.
Do not use the wrong kind of brake fluid. A few drops of miner-
al based oil, such as engine oil, in
your brake system can damage
brake system parts.
Information
Use only the specified brake fluid
Refer to “Recommended Lubricants
and Capacities” in chapter 8.
Checking the washer fluid
level
Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary. Plain water may be used if
washer fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold cli-
mates to prevent freezing.

If the brake system requires fre-
quent additions of fluid this
could indicate a leak in the
brake system. We recommend
that the vehicle be inspected by
a HYUNDAI authorised repairer.
WARNING
Do not allow brake fluid to come
in contact with your eyes. If
brake fluid comes in contact
with your eyes, flush your eyes
with clean water for at least 15
minutes and get immediate
medical attention.

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 dis-
colouration. If they do contact the
interior parts, wipe them off immedi-
ately. 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
colour of the leather may fade or
the surface may get stripped off.
Cleaning the upholstery andinterior trim
Vinyl (if equipped)
Remove dust and loose dirt from
vinyl with a whisk broom or vacuum
cleaner. Clean vinyl surfaces with a
vinyl cleaner.
Fabric (if equipped)
Remove dust and loose dirt from fab-
ric with a whisk broom or vacuum
cleaner. Clean with a mild soap solu-
tion recommended for upholstery or
carpets. Remove fresh spots imme-
diately with a fabric spot cleaner. If
fresh spots do not receive immediate
attention, the fabric can be stained
and its colour can be affected. Also,
its fire-resistant properties can be
reduced if the material is not proper-
ly maintained.
Using anything but recommended
cleaners and procedures may
affect the fabric’s appearance and
fire-resistant properties.
Leather (if equipped)
Features of seat leather
- Leather is made from the outerskin of an animal, which goes
through a special process to be
available for us. Since it is a natu-
ral product, each part differs in
thickness or density. Wrinkles
may appear as a natural result of
stretching and shrinking depend-
ing on the temperature and
humidity.
- The seat is made of stretchable fabric to improve comfort.
- The parts contacting the body are curved and the side supporting
area is high which provides driv-
ing comfort and stability.
- Wrinkles may appear naturally from usage. It is not a fault of the
product.

*1: Refer to the recommended SAE viscosity numbers on the next page.
*2: Engine oils labelled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel eco n-
omy by reducing the amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure
in everyday driving, but in a year’s time, they can offer significant cost and energy savings.
