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 chapter 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorized HYUNDAI dealer.
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the
battery and cables as described in
chapter 8. The level of charge in your
battery can be checked by an authorized
HYUNDAI dealer or a service station.
Check spark plugs and ignition
system
Inspect your spark plugs as described in
chapter 8 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.
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 instructions on the
container. Window washer anti-freeze is
available from an authorized HYUNDAI
dealer and most auto parts outlets. Do
not use engine coolant or other types
of antifreeze as these may damage the
paint finish.
Do not 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
the parking brake may freeze, apply
it only temporarily while you put the
gear selector lever in P and block the
rear wheels so the car cannot roll. Then
release the parking brake.
Do not let ice and snow accumulate
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 components is not obstructed.
Don't place foreign objects
or materials in the engine
compartment
Placement of foreign object or materials
which prevent cooling of the engine, in
the engine compartment, may cause a
failure or combustion. The manufacturer
is not responsible for the damage caused
by such placement.
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 heated key with care to avoid injury.

Tire pressure monitoring system
WARNING
Over-inflation or under-inflation can
reduce tire life, adversely affect vehicle
handling, and lead to sudden tire failure
that may cause loss of vehicle control
resulting in an accident.
Each tire, including the spare (if
provided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard
or tire inflation pressure label. (If your
vehicle has tires of a different size than
the size indicated on the vehicle placard
or tire inflation pressure label, you should
determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your tires is
significantly under-inflated. Accordingly,
when the low tire pressure telltale
illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on
a significantly underinflated tire causes
the tire to overheat and can lead to tire
failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle’s handling and
stopping ability.Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating
properly. The TPMS malfunction
indicator is combined with the low
tire pressure telltale. When the system
detects a malfunction, the telltale will
flash for approximately one minute and
then remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be able
to detect or signal low tire pressure as
intended. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that
prevent the TPMS from functioning
properly.
Always check the TPMS malfunction
telltale after replacing one or more tires
or wheels on your vehicle to ensure that
the replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.

08
8-11
If either telltale illuminates, immediately
reduce your speed, avoid hard cornering
and anticipate increased stopping
distances. You should stop and check
your tires as soon as possible. Inflate the
tires to the proper pressure as indicated
on the vehicle’s placard or tire inflation
pressure label located on the driver’s
side center pillar outer panel.
If you cannot reach a service station or
if the tire cannot hold the newly added
air, replace the low pressure tire with the
spare tire.
The Low Tire Pressure Telltale will remain
on and the TPMS Malfunction Indicator
may blink for one minute and then
remain illuminated (when the vehicle
is driven approximately 10 minutes at
speed above 15.5 mph (25km/h)) until
you have the low pressure tire repaired
and replaced on the vehicle.
Information
The spare tire is not equipped with a tire
pressure sensor.
CAUTION
In winter or cold weather, the Low Tire
Pressure Telltale may be illuminated if
the tire pressure was adjusted to the
recommended tire inflation pressure
in warm weather. It does not mean
your TPMS is malfunctioning because
the decreased temperature leads to a
proportional lowering of tire pressure.
When you drive your vehicle from a
warm area to a cold area or from a cold
area to a warm area, or the outside
temperature is greatly higher or lower,
you should check the tire inflation
pressure and adjust the tires to the
recommended tire inflation pressure.
WARNING
Low pressure damage
Significantly low tire pressure makes
the vehicle unstable and can contribute
to loss of vehicle control and increased
braking distances.
Continued driving on low pressure tires
can cause the tires to overheat and fail.

Emergency Situations8-12
TPMS (Tire Pressure
Monitoring System)
malfunction indicator
The TPMS Malfunction Indicator
will illuminate after it blinks for
approximately one minute when there
is a problem with the Tire Pressure
Monitoring System.
We recommend that the system be
checked by an authorized HYUNDAI
dealer.
NOTICE
If there is a malfunction with the TPMS,
the Low Tire Pressure Position Telltale
will not be displayed even though the
vehicle has an under-inflated tire.
NOTICE
The TPMS Malfunction Indicator may
illuminate after blinking for one minute
if the vehicle is near electric power
supply cables or radio transmitters
such as police stations, government
and public offices, broadcasting
stations, military installations, airports,
transmitting towers, etc.
Additionally, the TPMS Malfunction
Indicator may illuminate if snow chains
are used or electronic devices such as
computers, chargers, remote starters,
navigation, etc. This may interfere with
normal operation of the TPMS.
Changing a tire with TPMS
If you have a flat tire, the Low Tire
Pressure and Position telltales will come
on. We recommend that the flat tire be
repaired by an authorized HYUNDAI
dealer as soon as possible or replace the
flat tire with the spare tire.
NOTICE
It is recommended that you do not use a
puncture-repairing agent not approved
by a HYUNDAI dealer to repair and/or
inflate a low pressure tire. Tire sealant
not approved by a HYUNDAI dealer may
damage the tire pressure sensor.
The spare tire (if equipped) does not
come with a tire pressure monitoring
sensor. When the low pressure tire or
the flat tire is replaced with the spare
tire, the Low Tire Pressure Telltale will
remain on. Also, the TPMS Malfunction
Indicator will illuminate after blinking
for one minute if the vehicle is driven
at speed above 15.5 mph (25km/h) for
approximately 10 minutes.
Once the original tire equipped with
a tire pressure monitoring sensor is
reinflated to the recommended pressure
and reinstalled on the vehicle, the
Low Tire Pressure Telltale and TPMS
Malfunction Indicator will go off within a
few minutes of driving.
If the indicators do not extinguish after a
few minutes, please visit an authorized
HYUNDAI dealer.

08
8-17
If you have a tire gauge, check the tire
pressure (see “Tires and Wheels” in
chapter 2 for tire pressure instructions.).
If the pressure is lower or higher than
recommended, drive slowly to the
nearest service station and adjust it to
the recommended pressure. Always
reinstall the valve cap after checking
or adjusting tire pressure. If the cap
is not replaced, air may leak from the
tire. If you lose a valve cap, buy another
and install it as soon as possible. After
changing tires, secure the flat tire and
return the jack and tools to their proper
storage locations. If it is hard to secure
the flat tire, put the flat tire in the
luggage compartment.
NOTICE
• Check the tire pressure as soon
as possible after installing a spare
tire. Adjust it to the recommended
pressure.
• Check and tighten the wheel lug
nuts after driving over 30 miles (50
km), after the spare tire is installed.
Recheck the tire wheel lug nuts after
driving over 620 miles (1,000 km)
after the replaced tire is reinstalled.
CAUTION
Your vehicle has metric threads on the
studs and lug nuts. Make certain during
tire changing that the same nuts that
were removed are reinstalled. If you
have to replace your lug nuts make
sure they have metric threads to avoid
damaging the studs and ensure the
wheel is properly secured to the hub.
Consult an authorized HYUNDAI dealer
for assistance.
If any of the equipment such as the jack,
lug nuts, studs, or other equipment is
damaged or in poor condition, do not
attempt to change the tire and call for
assistance.
Use of compact spare tires (if equipped)
Compact spare tires are designed for
emergency use only. Drive carefully on
the compact spare tire and always follow
the safety precautions.
WARNING
To prevent compact spare tire failure
and loss of control possibly resulting in
an accident:
• Use the compact spare tire only in an
emergency.
• NEVER operate your vehicle over 50
mph (80 km/h).
• Do not exceed the vehicle’s
maximum load rating or the load
carrying capacity shown on the
sidewall of the compact spare tire.
• Do not use the compact spare tire
continuously. Repair or replace the
original tire as soon as possible to
avoid failure of the compact spare
tire.
