2011 Hyundai Sonata weight

Introduction4
1"E85" fuel is an alternative fuel com-
prised of 85 percent ethanol and 15 per-
cent gasoline, and is manufactured
exclusively for use in Flexible Fuel
Vehicles. “E85” is not compatible with
your vehicle. Use of “E85” may result in
poor engine performance and damage to
your vehicle's engine and fuel system.
HYUNDAI recommends that customers
do not use fuel with an ethanol content
exceeding 10 percent.
Use of MTBEHYUNDAI recommends avoiding fuels
containing MTBE (Methyl Tertiary Butyl
Ether) over 15.0% vol. (Oxygen Content
2.7% weight) in your vehicle.
Fuel containing MTBE over 15.0% vol.
(Oxygen Content 2.7% weight) may
reduce vehicle performance and produce
vapor lock or hard starting.
Do not use methanolFuels containing methanol (wood alco-
hol) should not be used in your vehicle.
This type of fuel can reduce vehicle per-
formance and damage components of
the fuel system.Gasolines for cleaner airTo help contribute to cleaner air,
HYUNDAI recommends that you use
gasolines treated with detergent addi-
tives, which help prevent deposit forma-
tion in the engine. These gasolines will
help the engine run cleaner and enhance
performance of the Emission Control
System.Operation in foreign countriesIf you are going to drive your vehicle in
another country, be sure to:
• Observe all regulations regarding reg-
istration and insurance.
• Determine that acceptable fuel is avail- able.
CAUTION
Your New Vehicle Limited Warrantymay not cover damage to the fuel system and any performance prob-lems that are caused by the use of fuels containing methanol or fuelscontaining MTBE (Methyl TertiaryButyl Ether) over 15.0% vol.(Oxygen Content 2.7% weight.)
CAUTION
Never use gasohol which containsmethanol. Discontinue use of any gasohol product which impairs dri-vability.
CAUTION
Your New Vehicle Limited Warrantydoes not cover damage to the fuelsystem or any performance prob- lems caused by the use of “E85” fuel.

3Infant or small childAll 50 states have child restraint laws. You
should be aware of the specific require-
ments in your state. Child and/or infant
seats must be properly placed and
installed in the rear seat. For more infor-
mation about the use of these restraints,
refer to “Child restraint system” in this
section.
✽
NOTICESmall children are best protected from
injury in an accident when properly
restrained in the rear seat by a child
restraint system that meets the require-
ments of the Federal Motor Vehicle
Safety Standards. Before buying any
child restraint system, make sure that it
has a label certifying that it meets
Federal Motor Vehicle Safety Standard
213. The restraint must be appropriate
for your child's height and weight.
Check the label on the child restraint for
this information. Refer to “Child
restraint system” in this section.
Larger childrenChildren who are too large for child
restraint systems should always occupy
the rear seat and use the available
lap/shoulder belts. The lap portion should
be fastened snug on the hips and as low
as possible. Check belt fit periodically. A
child's squirming could put the belt out of
position. Children are afforded the most
safety in the event of an accident when
they are restrained by a proper restraint
system in the rear seat. If a larger child
(over age 12) must be seated in the front
seat, the child should be securely
restrained by the available lap/shoulder
belt and the seat should be placed in the
rearmost position. Children age 12 and
under should be restrained securely in
the rear seat. NEVER place a child age
12 and under in the front seat. NEVER
place a rear facing child seat in the front
seat of a vehicle.
WARNING
Every person in your vehicle needs
to be properly restrained at all
times, including infants and chil-
dren. Never hold a child in your
arms or lap when riding in a vehi-
cle. The violent forces created dur-
ing a crash will tear the child from
your arms and throw the child
against the interior. Always use a
child restraint appropriate for your
child's height and weight.

Safety features of your vehicle
Always be sure that you and all vehicle
occupants are seated and restrained
properly (sitting upright with the seat in
an upright position, centered on the seat
cushion, with the person's legs comfort-
ably extended, feet on the floor, and
wearing the safety belt properly) for the
most effective protection by the air bag
and the safety belt.
• The OCS may not function properly ifthe passenger takes actions which can
affect the classification system. These
include:
(1) Failing to sit in an upright position.
(2) Leaning against the door or center console.
(3) Sitting towards the sides or the front of the seat.
(4) Putting legs on the dashboard or resting them on other locations
which reduce the passenger weight
on the front seat.
(5) Improperly wearing the safety belt.
(6) Reclining the seat back.
C040301ABHCondition and operation in the front passenger occupant classification system*1) The system judges a person of adult size as an adult. When a smaller adult
sits in the front passenger seat, the
system may recognize him/her as a
child depending on his/her physique
and posture.
*2) Do not allow children to ride in the front passenger seat. When a larger
child who has outgrown a child
restraint system sits in the front pas-
senger seat, the system may recog-
nize him/her as an adult depending
upon his/jer physique or sitting posi-
tion. *3) Never install a child restraint system
on the front passenger seat.
WARNING
Riding in an improper position or
placing weight on the front passen-
ger's seat when it is unoccupied by
a passenger adversely affects the
occupant classification system
(OCS).

• Do not place an electronic device
such as a laptop computer on the
front passenger seat. Its elec-
tronic field may cause the OCS to
switch to the "on" condition and
thus allow the passenger air bag
to deploy needlessly in a colli-
sion, increasing your repair
costs.
• A smaller-stature adult in the front passenger’ seat who is not
seated correctly (for example:
seat excessively reclined, leaning
on the door or center console, or
hips shifted forward in the seat)
can cause a condition where the
occupant classification system
senses less weight than if the
occupant were seated properly
(sitting upright with the seatback
in an upright position, centered
on the seat cushion with their
seat belt on, legs comfortably
extended and their feet on the
floor).
This condition can result in an
adult potentially being misclassi-
fied as a child and illumination of
the PASS AIR BAG "OFF" indica-
tor.
(Continued)
• Accident statistics show thatchildren are safer if they are
restrained in the rear, as opposed
to the front seat. It is recom-
mended that child restraints be
secured in a rear seat, including
an infant riding in a rear-facing
infant seat, a child riding in a for-
ward-facing child seat and an
older child riding in a booster
seat.
• Air bags can only be used once – have an authorized HYUNDAI
dealer replace the air bag imme-
diately after deployment.
• The occupant classification sys- tem may not work properly if
water, coffee or any other liquid
including rain gets on the seat.
Keep the front seat dry at all
times.
(Continued)
• If the PASS AIR BAG "OFF" indi-cator is illuminated when the
front passenger's seat is occu-
pied by an adult and he/she sits
properly (sitting upright with the
seatback in an upright position,
centered on the seat cushion
with their seat belt on, legs com-
fortably extended and their feet
on the floor), have that person sit
in the rear seat.
• Do not modify or replace the front passenger seat. Don't place any-
thing on or attach anything such
as a blanket or seat heater to the
front passenger seat. This can
adversely affect the occupant
classification system.
• Do not sit on sharp objects such as tools when occupying the
front passenger seat. This can
adversely affect the occupant
classification system.
• Do not use accessory seat cov- ers on the front seats.

Driving your vehicle
Your vehicle's fuel economy depends
mainly on your style of driving, where you
drive and when you drive.
Each of these factors affects how many
miles (kilometers) you can get from a gal-
lon (liter) of fuel. To operate your vehicle
as economically as possible, use the fol-
lowing driving suggestions to help save
money in both fuel and repairs:
• Drive smoothly. Accelerate at a moder-ate 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
possible. Always maintain a safe dis-
tance from other vehicles so you can
avoid unnecessary braking. This also
reduces brake wear.
• Drive at a moderate speed. The faster you drive, the more fuel your car uses.
Driving at a moderate speed, especial-
ly on the highway, is one of the most
effective ways to reduce fuel consump-
tion. • Don't "ride" the brake pedal. This can
increase fuel consumption and also
increase wear on these components.
In addition, driving with your foot rest-
ing on the brake pedal may cause the
brakes to overheat, which reduces
their effectiveness and may lead to
more serious consequences.
• 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.
• Be sure that the wheels are aligned correctly. Improper alignment can
result from hitting curbs or driving too
fast over irregular surfaces. Poor align-
ment causes faster tire wear and may
also result in other problems as well as
greater fuel consumption. • 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 7. If you drive your
car in severe conditions, more frequent
maintenance is required (see section 7
for details).
• Keep your car clean. For maximum service, your vehicle 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 con-
sumption and also contribute to corro-
sion.
• Travel lightly. Don't carry unnecessary weight in your car. Weight reduces fuel
economy.
• 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.ECONOMICAL OPERATION

Driving your vehicle
Use high quality ethylene glycol
coolantYour vehicle is delivered with high quality
ethylene glycol coolant in the cooling
system. It is the only type of coolant that
should be used because it helps prevent
corrosion in the cooling system, lubri-
cates the water pump and prevents
freezing. Be sure to replace or replenish
your coolant in accordance with the
maintenance schedule in section 7.
Before winter, have your coolant tested to
assure that its freezing point is sufficient
for the temperatures anticipated during
the winter.Check battery and cablesWinter puts additional burdens on the
battery system. Visually inspect the bat-
tery and cables as described in section
7. The level of charge in your battery can
be checked by an authorized HYUNDAI
dealer or a service station.
Change to "winter weight" oil if
necessaryIn 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 HYUNDAI dealer.Check spark plugs and ignition
systemInspect your spark plugs as described in
section 7 and replace them if necessary.
Also check all ignition wiring and compo-
nents to be sure they are not cracked,
worn or damaged in any way.
WARNING
- Tire chains
• The use of chains may adverselyaffect vehicle handling.
• Do not exceed 20 mph (30 km/h) or the chain manufacturer’s rec-
ommended speed limit, whichev-
er is lower.
• Drive carefully and avoid bumps, holes, sharp turns, and other
road hazards, which may cause
the vehicle to bounce.
• Avoid sharp turns or locked- wheel braking.
CAUTION
• Chains that are the wrong size or improperly installed can damageyour vehicle's brake lines, sus-pension, body and wheels.
• Stop driving and retighten the chains any time you hear themhitting the vehicle.
