HYUNDAI SONATA 2021 Owners Manual

Emergency Situations
7-6
If your temperature gauge indicates
overheating, you experience a loss of
power, or hear loud pinging or knocking,
the engine may be overheating. If this
happens, you should:
1.
Pull o
ff the road and stop as soon as it
is safe to do so.
2.

Place the shift butt
on in P (Park)
and set the parking brake. If the air
conditioning is ON, turn it OFF.
3.

If engine coolan
t is running out under
the vehicle or steam is coming out
from the hood, stop the engine. Do
not open the hood until the coolant
has stopped running or the steaming
has stopped. If there is no visible
loss of engine coolant and no steam,
leave the engine running and check
to be sure the engine cooling fan is
operating. If the fan is not running,
turn the engine off.
WARNING
While the engine is running,
keep hands, clothing and tools
away from the moving parts
such as the cooling fan and
drive belt to prevent serious
injury.
4.
Check f

or coolant leaking from the
radiator, hoses or under the vehicle. (If
the air conditioning had been in use, it
is normal for cold water to be draining
from it when you stop.)
5.

If engine coolan
t is leaking out, stop
the engine immediately and call the
nearest authorized HYUNDAI dealer
for assistance.
WARNING
Your vehicle is equipped
with a pressurized coolant
reserve tank. NEVER remove
the engine coolant reservoir
tank/radiator cap or the drain
plug while the engine and
radiator are HOT. Hot coolant
and steam may blow out under
pressure, causing serious
injury.
Turn the engine off and wait until the
engine cools down. Use extreme care
when removing the engine coolant
reservoir tank/radiator cap. Wrap
a towel or thick rag around it, and
turn it counterclockwise slowly to
release some of the pressure from the
system. Step back while the pressure is
released.
When you are sure all the pressure has
been released, continue turning the cap
counterclockwise to remove it.
6.

If y

ou cannot find the cause of the
overheating, wait until the engine
temperature has returned to normal.
Then, if coolant has been lost,
carefully add coolant to the reservoir
to bring the fluid level in the reservoir
up to the halfway mark.
7.
Pr

oceed with caution, keeping alert
for further signs of overheating. If
overheating happens again, call
an authorized HYUNDAI dealer for
assistance.
CAUTION
Serious loss of coolant indicates a
leak in the cooling system and should
be checked as soon as possible by an
authorized HYUNDAI dealer.

Emergency Situations
7-8
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 under-inflated 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.
NOTICE
If any of the below happens, have
the system checked by an authorized
HYUNDAI dealer.
1.
The L
ow Tire Pressure TPMS
Malfunction Indicator does not
illuminate for 3 seconds when the
ignition switch is placed to the ON
position or engine is running.

Low Tire Pressure Telltale
Low Tire Pressure LCD Display
with Position Indicator
ODN8049019L
When the tire pressure monitoring
system warning indicators are
illuminated and the warning message
is displayed on the cluster LCD
display, one or more of your tires is
significantly under-inflated. The LCD
position indicator will indicate which
tire is significantly under-inflated by
illuminating the corresponding position
light.
If any of your tire pressures are indicated
as being low, 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. (if equipped)
The Low Tire Pressure LCD position
indicator will remain on and the TPMS
Malfunction Indicator may blink for one
minute and then remain illuminated until
you have the low pressure tire repaired
and replaced on the vehicle.
NOTICE
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 Situations
7-10
TPMS 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.
Have the system checked by an
authorized HYUNDAI dealer as soon as
possible.
NOTICE
If there is a malfunction with the
TPMS, the individual tire pressures
in the cluster LCD display will not be
available. Have the system checked by
an authorized HYUNDAI dealer as soon
as possible.
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 LCD position indicator will
come on. Have the flat tire repaired by an
authorized HYUNDAI dealer as soon as
possible or replace the flat tire with the
spare tire. (if equipped)
CAUTION
It is recommended that you do not use a
puncture-repairing agent not approved
by HYUNDAI dealer to repair and/or
inflate a low pressure tire. Tire sealant
not approved by HYUNDAI dealer may
damage the tire pressure sensor.
The spare tire 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 LCD position indicator 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 (25 km/h) for
approximately 20 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 LCD position indicator and
TPMS Malfunction Indicator will go off
within a few minutes of driving.
If the indicators do not disappear after a
few minutes, please visit an authorized
HYUNDAI dealer.

07
7-11
Each wheel is equipped with a tire
pressure sensor mounted inside the tire
behind the valve stem (except for the
spare tire). You must use TPMS specific
wheels. It is recommended that you
always have your tires serviced by an
authorized HYUNDAI dealer.
You may not be able to identify a tire
with low pressure by simply looking at it.
Always use a good quality tire pressure
gauge to measure the tire’s inflation
pressure. Please note that a tire that is
hot (from being driven) will have a higher
pressure measurement than a tire that is
cold.
A cold tire means the vehicle has been
sitting for 3 hours and driven for less
than 1 mile (1.6 km) in that 3 hour period.
Allow the tire to cool before measuring
the inflation pressure. Always be sure
the tire is cold before inflating to the
recommended pressure.
WARNING
• The TPMS cannot alert you to severe
and sudden tire damage caused by
external factors such as nails or road
debris.
• If you feel any vehicle instability,
immediately take your foot off
the accelerator, apply the brakes
gradually with light force, and slowly
move to a safe position off the road.
WARNING
Tampering with, modifying, or disabling
the Tire Pressure Monitoring System
(TPMS) components may interfere
with the system’s ability to warn the
driver of low tire pressure conditions
and/or TPMS malfunctions. Tampering
with, modifying, or disabling the Tire
Pressure Monitoring System (TPMS)
components may void the warranty for
that portion of the vehicle.

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.
