2019 HYUNDAI SONATA HYBRID air condition

Maintenance
Because the sidewall of a low
aspect ratio tire is shorter than
a standard tire, the rim of thewheel and the tire itself is more
easily susceptible to damage.Use caution when driving and
follow the guidelines below to
help minimize damage to thewheel and tire:
- When driving on a rough roador off road, drive cautiously
because tires and wheels may
be damaged. And after driving,inspect tires and wheels.
- When passing over a pothole, speed bump, manhole, or curb
stone, drive slowly so that thetires and wheels are not dam-
aged.
- If the tire is subjected to a severe impact, have the tire
and wheel inspected by an
authorized HYUNDAI dealer.
- Inspect the tire condition and pressure every 3,000km (1,800miles).
CAUTION
It is not easy to recognize tire
damage with your own eyes.But if there is the slightest
hint of tire damage, have the
tire checked or replaced
because the tire damage may
cause air leakage from the
tire.
If the tire is damaged by driv-
ing on a rough road, off road,
pothole, manhole, or curb
stone, it will not be covered by
the warranty.

Corrosion protection
Protecting your vehicle from corro-
sion
By using the most advanced design
and construction practices to combat
corrosion, HYUNDAI produces 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 alsorequired.
Common causes of corrosion
The most common causes of corro-
sion on your vehicle are:
Road salt, dirt and moisture that isallowed to accumulate underneath
the vehicle.
coatings by stones, gravel, abra-
sion or minor scrapes and dents
which leave unprotected metal
exposed to corrosion.
High-corrosion areas
If you live in an area where your vehi-
cle is regularly exposed to corrosive
materials, corrosion protection is
particularly important. Some of the
common causes of accelerated cor-
rosion are road salts, dust control
chemicals, ocean air and industrialpollution.
Moisture breeds corrosion
Moisture creates the conditions in
which corrosion is most likely to
occur. For example, corrosion is
accelerated by high humidity, partic-
ularly when temperatures are just
above freezing. In such conditions,
the corrosive material is kept in con-
tact with the car surfaces by moisture
that is slow to evaporate.
Mud is particularly corrosive
because it is slow to dry and holds
moisture in contact with the vehicle.
Although the mud appears to be dry,it can still retain the moisture andpromote corrosion.
High temperatures can also acceler-
ate corrosion of parts that are not
properly ventilated so the moisture
can be dispersed. For all these rea-
sons, it is particularly important to
keep your vehicle clean and free of
mud or accumulations of other mate-
rials. This applies not only to the vis-
ible surfaces but particularly to the
underside of the vehicle.

Maintenance
Do not operate the engine in con-fined or closed areas (such as
garages) any more than what is
necessary to move the vehicle in orout of the area.
When the vehicle is stopped in an open area for more than a short
time with the engine running,
adjust the ventilation system (as
needed) to draw outside air into the
vehicle.
Never sit in a parked or stopped vehicle for any extended time with
the engine running.
When the engine stalls or fails to start, excessive attempts to restart
the engine may cause damage tothe emission control system.Operating precautions for cat-
alytic converters (if equipped)Your vehicle is equipped with a cat-
alytic converter emission control
device.
To prevent damage to the catalytic
converter and to your vehicle, take
the following precautions:
The exhaust system and cat-
alytic converter are very hot
during and immediately after
the engine has been running. To
avoid SERIOUS INJURY or
DEATH:
Do not park, idle, or drive the
vehicle over or near flamma-
ble objects, such as grass,
vegetation, paper, leaves, etc.
A hot exhaust system can
ignite flammable items under
your vehicle.
Keep away from the exhaust
system and catalytic convert-
er or you may get burned.
Also, Do not remove the heat
sink around the exhaust sys-
tem, do not seal the bottom of
the vehicle, and do not coat
the vehicle for corrosion con-
trol. It may present a fire risk
under certain conditions.
