2011 Hyundai Sonata Hybrid brake light

What to do in an emergency
12 6
You may not be able 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 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 measur-
ing the inflation pressure. Always be
sure the tire is cold before inflating to
the recommended pressure.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 inter-
ference that may cause undesired
operation.
CAUTION
Do not use any tire sealant
except the Tire Mobility Kit
approved by HYUNDAI if your
vehicle is equipped with a Tire
Pressure Monitoring System.
The liquid sealant can damage
the tire pressure sensors.
WARNING - Protecting
TPMS
Tampering with, modifying, or
disabling the Tire Pressure
Monitoring System (TPMS) com-
ponents may interfere with the
system's ability to warn the driv-
er of low tire pressure condi-
tions and/or TPMS malfunctions.
Tampering with, modifying, or
disabling the Tire Pressure
Monitoring System (TPMS) com-
ponents may void the warranty
for that portion of the vehicle.
WARNING- TPMS
The TPMS cannot alert you to
severe and sudden tire dam-
age caused by external fac-
tors such as nails or road
debris.
If you feel any vehicle instabil-
ity, immediately take your foot
off the accelerator, apply the
brakes gradually and with
light force, and slowly move to
a safe position off the road.
WARNING
Changes or modifications not
expressly approved by the party
responsible for compliance
could void the user’s authority
to operate the equipment.

OWNER MAINTENANCE
The following lists are vehicle checks and
inspections that should be performed by
the owner or an authorized HYUNDAI
dealer at the frequencies indicated to
help ensure safe, dependable operation
of your vehicle.
Any adverse conditions should be
brought to the attention of your dealer as
soon as possible.
These Owner Maintenance Checks are
generally not covered by warranties and
you may be charged for labor, parts and
lubricants used.Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check coolant level in coolant reser-
voirs (engine and inverter).
Check the windshield washer fluid
level.
Look for low or under-inflated tires.
While operating your vehicle:
Note any changes in the sound of the
exhaust or any smell of exhaust fumes
in the vehicle.
Check for vibrations in the steering
wheel. Notice any increased steering
effort or looseness in the steering
wheel, or change in its straight-ahead
position.
Notice if your vehicle constantly turns
slightly or “pulls” to one side when trav-
eling on smooth, level road.
When stopping, listen and check for
unusual sounds, pulling to one side,
increased brake pedal travel or “hard-
to-push” brake pedal.
If any slipping or changes in the oper-
ation of your transaxle occurs, check
the transaxle fluid level.
Check automatic transaxle P (Park)
function.
Check parking brake.
Check for fluid leaks under your vehicle
(water dripping from the air condition-
ing system during or after use is nor-
mal).
Check inverter coolant.
WARNING
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot coolant
and steam may blow out under
pressure. This could cause burns
or other serious injury.

Maintenance
6 7
At least monthly:
Check coolant level in the engine
coolant reservoir and inverter coolant.
Check the operation of all exterior
lights, including the stoplights, turn sig-
nals and hazard warning flashers.
Check the inflation pressures of all
tires including the spare.
At least twice a year
(i.e., every Spring and Fall):
Check radiator, heater and air condi-
tioning hoses for leaks or damage.
Check windshield washer spray and
wiper operation. Clean wiper blades
with clean cloth dampened with wash-
er fluid.
Check headlight alignment.
Check muffler, exhaust pipes, shields
and clamps.
Check the lap/shoulder belts for wear
and function.
Check for worn tires and loose wheel
lug nuts.
At least once a year:
Clean body and door drain holes.
Lubricate door hinges and checks, and
hood hinges.
Lubricate door and hood locks and
latches.
Lubricate door rubber weatherstrips.
Check the air conditioning system.
Inspect and lubricate automatic
transaxle linkage and controls.
Clean battery and terminals.
Check the brake fluid level.
Check the drive belt.

LIGHT BULBS
Use only bulbs of the specified wattage.
✽
✽
NOTICE
After heavy, driving rain or washing,
headlight and taillight lenses could
appear frosty. This condition is caused by
the temperature difference between the
lamp inside and outside. This is similar
to the condensation on your windows
inside your vehicle during the rain and
doesn’t indicate a problem with your
vehicle. If the water leaks into the lamp
bulb circuitry, have the vehicle checked
by an authorized HYUNDAI dealer.WARNING - Working on
the lights
Prior to working on the light, firmly
apply the parking brake, ensure
that the engine start/stop button is
turned to the LOCK position and
turn off the lights to avoid sudden
movement of the vehicle and burn-
ing your fingers or receiving an
electric shock.
CAUTION
Be sure to replace the burned-out
bulb with one of the same wattage
rating. Otherwise, it may cause
damage to the fuse or electric
wiring system.
CAUTION
If you don’t have necessary tools,
the correct bulbs and the expertise,
consult an authorized HYUNDAI
dealer. In many cases, it is difficult
to replace vehicle light bulbs
because other parts of the vehicle
must be removed before you can
get to the bulb. This is especially
true if you have to remove the head-
light assembly to
get to the bulb(s).
Removing/installingthe headlight
assembly can result in damage to
the vehicle.
WARNING
When you replace the bulb of front-
light, be careful the HPCU system,
high voltage cable (orange color)
and high voltage components for
hybrid.
It is very dangerous because the
HPCU has the high voltage. Always
pay strongly attention to your
hands. If not, it may result in the
electric shock or burns.

Maintenance
Aluminum wheel maintenance
The aluminum wheels are coated with a
clear protective finish.
Do not use any abrasive cleaner, pol-
ishing compound, solvent, or wire
brushes on aluminum wheels. They
may scratch or damage the finish.
Use only a mild soap or neutral deter-
gent, and rinse thoroughly with water.
Also, be sure to clean the wheels after
driving on salted roads. This helps pre-
vent corrosion.
Avoid washing the wheels with high-
speed car wash brushes.
Do not use any cleaners containing
acid or acid detergents. It may damage
and corrode the aluminum wheels
coated with a clear protective finish.
Corrosion protection
Protecting your vehicle from corrosion
By using the most advanced design and
construction practices to combat corro-
sion, we produce cars of the highest
quality. However, this is only part of the
job. To achieve the long-term corrosion
resistance your vehicle can deliver, the
owner's cooperation and assistance is
also required.
Common causes of corrosion
The most common causes of corrosion
on your car are:

allowed to accumulate underneath the
car.
Removal of paint or protective coatings
by stones, gravel, abrasion or minor
scrapes and dents which leave unpro-
tected metal exposed to corrosion.WARNING
After washing the vehicle, test the
brakes while driving slowly to see if
they have been affected by water. If
braking performance is impaired,
dry the brakes by applying them
lightly while maintaining a slow for-
ward speed.
CAUTION
If the under cover is opened while
driving, water or materials rusting
the engine room may enter the
engine room. It may result in the
damage of Hybrid system.
