2010 Hyundai Sonata inflation pressure

1FEATURES OF YOUR HYUNDAI40

Upon deployment, tear seams molded
directly into the pad covers will separate
under pressure from the expansion of the
airbags. Further opening of the covers
then allows full inflation of the airbags.A fully inflated airbag, in combination with
a properly worn seat belt, slows the driver's
forward motion, reducing the risk of head
and chest injury.
After complete inflation, the airbag
immediately starts deflating, enabling the
driver to maintain forward visibility and the
ability to steer or operate other controls.
B240B03L
The airbag modules are located both in the
center of the steering wheel and in the front
passenger's panel above the glove box.
When the SRSCM detects a sufficiently
severe impact to the front of the vehicle, it
will automatically deploy the front airbags.
CAUTION:
o Do not install or place any accesso-
ries (drink holder, cassette holder,
sticker, etc.) on the front passenger's
panel above the glove box in a vehicle
with a passenger's airbag. Such ob-
jects may become dangerous pro-
jectiles and cause injury if the
passenger's airbag inflates.
o When installing a container of liquid
air freshener inside the vehicle, do
not place it near the instrument cluster
nor on the instrument panel surface.
If there is any leakage from the air
freshener onto these areas
(instrument cluster, instrument panel
or air ventilator), it may damage these

o Travel lightly. Don't carry unnecessary
weight in your car. Weight reduces fuel
economy.
o Don't let the engine idle longer than
necessary. If you are waiting (and not in
traffic), turn off your engine and restart
only when you're ready to go.
o Remember, your Hyundai does not re-
quire extended warm-up. After the en-
gine has started, allow the engine to run
for 10 to 20 seconds prior to placing the
vehicle in gear. In very cold weather,
however, give your engine a slightly
longer warm-up period.
o Don't "lug" or "over-rev" the engine.
Lugging is driving too slowly in too high
a gear resulting in the engine bucking.
If this happens, shift to a lower gear.
Over-revving is racing the engine
beyond its safe limit. This can be avoided
by shifting at the recommended speeds.
o Use your air conditioning sparingly. The
air conditioning system is operated by
engine power so your fuel economy is
reduced when you use it. o Take care of your tires. Keep them
inflated to the recommended pressure.
Incorrect inflation, either too much or
too little, results in unnecessary tire
wear. Check the tire pressures at least
once a month.
o Be sure that the wheels are aligned
correctly. Improper alignment can result
from hitting curbs or driving too fast over
irregular surfaces. Poor alignment
causes faster tire wear and may also
result in other problems as well as
greater fuel consumption.
o Keep your car in good condition. For
better fuel economy and reduced
maintenance costs, maintain your car
in accordance with the maintenance
schedule in Section 5. If you drive your
car in severe conditions, more frequent
maintenance is required (see Section 5
for details).
o Keep your car clean. For maximum
service, your Hyundai should be kept
clean and free of corrosive materials. It
is especially important that mud, dirt,
ice, etc. not be allowed to accumulate
on the underside of the car. This extra
weight can result in increased fuel
consumption and also contribute to cor-
rosion.
DRIVING FOR ECONOMYC140A02A-AATYou can save fuel and get more miles from
your car if you follow these suggestions:
o Drive smoothly. Accelerate at a
moderate rate. Don't make "jack-rabbit"
starts or full-throttle shifts and maintain
a steady cruising speed. Don't race
between stoplights. Try to adjust your
speed to that of the other traffic so you
don't have to change speeds unneces-
sarily. Avoid heavy traffic whenever pos-
sible. Always maintain a safe distance
from other vehicles so you can avoid
unnecessary braking. This also reduces
brake wear.
o Drive at a moderate speed. The faster
you drive, the more fuel your car uses.
Driving at a moderate speed, especially
on the highway, is one of the most
effective ways to reduce fuel
consumption.
o Don't "ride" the brake or clutch pedal.
This can increase fuel consumption and
also increase wear on these
components. In addition, driving with
your foot resting on the brake pedal may
cause the brakes to overheat, which
reduces their effectiveness and may
lead to more serious consequences.

C160K01A-AATCarry Emergency EquipmentDepending on the severity of the weather
where you drive your car, you should carry
appropriate emergency equipment. Some
of the items you may want to carry include
tire chains, tow straps or chains, flashlight,
emergency flares, sand, a shovel, jumper
cables, a window scraper, gloves, ground
cloth, coveralls, a blanket, etc.
HIGHER SPEED MOTORINGC170A02A-AATPre-Trip Inspections1. Tires:
Adjust the tire inflation pressures to speci-
fication. Low tire inflation pressures will
result in overheating and possible failure
of the tires.
Avoid using worn or damaged tires which
may result in reduced traction or tire failure.NOTE:Never exceed the maximum tire inflation
pressure shown on the tires.2. Fuel, engine coolant and engine oil:
High speed travel consumes more fuel
than urban motoring. Do not forget to check
both engine coolant and engine oil.
3. Drive belt:
A loose or damaged drive belt may result
in overheating of the engine.
WARNING:
o Underinflated or overinflated tires
can cause poor handling, loss of
vehicle control, and sudden tire failure
leading to accidents, injuries, and
even death. Always check tires are
properly inflated before driving. Refer
to pages 2-23 and 8-3 for proper tire
pressures and further information.
o Driving on tires with no or insufficient
tread is dangerous. Worn-out tires
can result in loss of vehicle control,
collisions, injury, and even death.
Worn-out tires should be replaced as
soon as possible and should never be
used for driving. Always check tire
tread before driving your car. Refer
to 8-10 for further information and
tread limits.

TIRE PRESSURE MONITORING SYSTEM (TPMS)
ONF048131 C320A01JM-AAT
➀ TPMS Malfunction Indicator
➁ Low Tire Pressure Telltale
Each tire, including the spare (if pro-
vided), should be checked monthly when
cold and inflated to the inflation pres-
sure recommended by the vehicle manu-
facturer 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 de-
termine the proper tire inflation pres-
sure for those tires.)As an added safety feature, your ve-
hicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure tell-
tale when one or more of your tires is
significantly under-inflated. Accord-
ingly, 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 han-
dling 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 operat-
ing properly. The TPMS malfunction
indicator is provided by a separate tell-
tale, which displays the symbol "TPMS"
when illuminated. When the malfunc-
tion indicator is illuminated, the system
may not be able to detect or signal low
tire pressure as intended. TPMS mal-
functions 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.

36WHAT TO DO IN AN EMERGENCY
!
Low tire pressure telltale
When the tire pressure monitoring sys-
tem warning telltale is illuminated, one
or more of your tires is significantly
under-inflated.
Immediately reduce your speed, avoid
hard cornering and anticipate increased
stopping distances. You should stop
and check your tires as soon as pos-
sible. 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 ser-
vice station or if the tire cannot hold the
newly added air, replace the low pres-
sure tire with the temporary spare tire.
Then the TPMS malfunction indicator
or the Low Tire Pressure telltale may
turn on after restarting and about 20
minutes of continuous driving before
you have the low-pressure tire repaired
and reinstalled on the vehicle. 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 pres-
sure 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.
Always check your tire inflation pres-
sures when the tires are cold, before
you have driven on them.WARNING - Low pressure
Significantly low tire pressure makes
the vehicle unstable and can contrib-
ute to loss of vehicle control and
increased braking distances. Contin-
ued driving on low pressure tires will
cause the tires to overheat and fail.
TPMS (Tire pressure moni-
toring system) malfunction
indicator
The TPMS malfunction indicator turns
on and stays on when there is a problem
with the Tire Pressure Monitoring Sys-
tem. If the system is able to correctly
detect an under-inflation warning at the
same time as system failure then it will
illuminate both the TPMS malfunction
and the low tire pressure telltale, e.g. if
the Front Left sensor fails, the TPMS
malfunction indicator turns on, but if the
Front Right, Rear Left, or Rear Right tire
is under-inflated, the low tire pressure
telltale may turn on at the same time as
the TPMS malfunction indicator.

Have the system checked by an autho-
rized Hyundai dealer as soon as pos-
sible to determine the cause of the
problem.
NOTE:
o The TPMS malfunction indicator
may be illuminated if the vehicle
is operated in areas close to elec-
tric power supply cables or radio
transmitters such as near police
stations, government and public
offices, broadcasting stations,
military installations, airports, or
transmitting towers, etc. which can
interfere with normal operation of
the Tire Pressure Monitoring Sys-
tem (TPMS).
o The TPMS malfunction indicator
may be illuminated if snow chains
or some electronic devices, such
as notebook computers, are used
in the vehicle. This can interfere
with normal operation of the Tire
Pressure Monitoring System
(TPMS).o If there is a failed tire sensor, it is
possible for the TPMS to tempo-
rarily learn a replacement sensor
if closely driven to another vehicle
that is also equipped with TPMS.
In rare cases, this may tempo-
rarily delay the TPMS malfunction
indicator from turning on.
Changing a tire with TPMS
If you have a flat tire, the Low Tire
Pressure telltale will turn on. Have the
flat tire repaired by an authorized Hyundai
dealer as soon as possible or replace
the flat tire with the temporary spare
tire. NEVER use a puncture-repairing
agent to repair and/or inflate a low
pressure tire. If used, you will have to
replace the tire pressure sensor.
Each wheel is equipped with a tire
pressure sensor mounted inside the tire
behind the valve stem. You must use
TPMS specific wheels. It is recom-
mended that you always have your tires
serviced by an authorized Hyundai
dealer.After you replace the low pressure tire
with the spare tire, the TPMS malfunc-
tion indicator or the Low Tire Pressure
telltale may illuminate after restarting
and driving for about 20 minutes.
Once the low pressure tire is re-inflated
to the recommended pressure and in-
stalled on the vehicle, the TPMS mal-
function indicator and the low tire pres-
sure telltale will extinguish. If the low
pressure and TPMS malfunction indi-
cators are not extinguished after about
20 minutes of continuous driving, please
visit an authorized Hyundai dealer.
You may not be able to identify a low tire
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 pres-
sure measurement than a tire that is
cold (from sitting stationary for at least
3 hours and driven less than 1 mile
during that 3 hour period). Allow the tire
to cool before measuring the inflation
pressure.

38WHAT TO DO IN AN EMERGENCY
!
!!
Always be sure the tire is cold before
inflating to the recommended pressure.
A cold tire means the vehicle has been
sitting for 3 hours and driven for less
than 1 mile in that 3 hour period.
NOTE:
o Do not use any tire sealant if your
vehicle is equipped with a Tire
Pressure Monitoring System. The
liquid sealant can damage the tire
pressure sensors.
o In order for the system to correctly
monitor tires for under-inflation,
there should be a total of 4 sen-
sors, one fitted to each of the four
wheel positions. There should be
no other sensors in the vehicle
including for the spare tire. This
could cause the system to moni-
tor the wrong sensor. WARNING - TPMS
o The TPMS cannot alert you to se-
vere and sudden tire damage
caused by external factors.
o If you feel any vehicle instability,
take your foot off the accelerator
and slowly move to a safe position
off the road.
WARNING:
Tampering with, modifying, or dis-
abling 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 malfunc-
tions. Tampering with, modifying,
or disabling the Tire Pressure Moni-
toring System (TPMS) components
may void the warranty for that por-
tion of the vehicle.This device complies with Part 15 of
the FCC rules.
Operation is subject to the following two
conditions:
1. This device may not cause harmful
interference, and
2. This device must accept any inter-
ference received, including interfer-
ence that may cause undesired op-
eration.
WARNING:
Changes or modifications not ex-
pressly approved by the party re-
sponsible for compliance could void
the user’s authority to operate the
equipment.
