2020 HYUNDAI SONATA HYBRID speed sensor

Safety System
3-44
• In addition to inflating in certain side
collisions, vehicles equipped with a
rollover sensor, side and curtain air
bags will inflate if the sensing system
detects a rollover.
When a rollover is detected, side and
curtain air bags will remain inflated
longer to help provide protection
from ejection, especially when used in
conjunction with the seat belts.
• To help provide protection, the air
bags must inflate rapidly. The speed
of air bag inflation is a consequence
of extremely short time in which
to inflate the air bag between the
occupant and the vehicle structures
before the occupant impacts those
structures. This speed of inflation
reduces the risk of serious or life-
threatening injuries and is thus a
necessary part of air bag design.
However, the rapid air bag inflation
can also cause injuries which can
include facial abrasions, bruises and
broken bones because the inflation
speed also causes the air bags to
expand with a great deal of force.
• There are even circumstances under
which contact with the air bag can
cause fatal injuries, especially if the
occupant is positioned excessively
close to the air bag.
You can take steps to help reduce the
risk of being injured by an inflating air
bag. The greatest risk is sitting too close
to the air bag. An air bag needs about 10
inches (25 cm) of space to inflate. NHTSA
recommends that drivers allow at least
10 inches (25 cm) between the center of
the steering wheel and the chest. WARNING
To reduce the risk of serious injury or
death from an inflating air bag, take the
following precautions:
• NEVER place a child restraint in the
front passenger seat.
Always properly restrain children
under age 13 in the rear seats of the
vehicle.
• Adjust the front passenger’s and
driver’s seats as far to the rear as
possible while allowing you to
maintain full control of the vehicle.
• Hold the steering wheel with
hands at the 9 o’clock and 3 o’clock
positions.
• NEVER place anything or anyone
between the air bag and the seat
occupant.
• Do not allow the front passenger
to place their feet or legs on the
dashboard.

Do Not Install a Child Restraint in the Front Passenger’s Seat
OHI039193N
Even though your vehicle is equipped
with the OCS, never install a child
restraint in the front passenger’s seat.
An inflating air bag can forcefully strike a
child or child restraint resulting in serious
or fatal injury.
WARNING
• NEVER place a rear-facing or front-
facing child restraint in the front
passenger’s seat of the vehicle.
• An inflating frontal air bag could
forcefully strike a child resulting in
serious injury or death.
• Always properly restrain children in
an appropriate child restraint in the
rear seat of the vehicle.
Why Didn’t My Air Bag Go Off in
a Collision?
Air bags are not designed to inflate in
every collision. There are certain types
of accidents in which the air bag would
not be expected to provide additional
protection. These include rear impacts,
second or third collisions in multiple
impact accidents, as well as low speed
impacts. Damage to the vehicle indicates
a collision energy absorption, and is not
an indicator of whether or not an air bag
should have inflated.
WARNING
To reduce the risk of an air bag
deploying unexpectedly and causing
serious injury or death:
• Do not hit or allow any objects to
impact the locations where air bags
or sensors are installed.
• Do not perform maintenance on or
around the air bag sensors. If the
location or angle of the sensors is
altered, the air bags may deploy
when they should not or may not
deploy when they should.
• Do not install bumper guards or
replace the bumper with a non-
genuine HYUNDAI parts. This may
adversely affect the collision and air
bag deployment performance.
• Place the ignition switch in the
LOCK/OFF or ACC position when the
vehicle is being towed to prevent
inadvertent air bag deployment.
• Have all air bag repairs conducted by
an authorized HYUNDAI dealer.

Air bag inflation conditions
ODN8039048L
Front air bags
Front air bags are designed to inflate
in a frontal collision depending on the
severity of impact of the front collision.
ODN8H030049N
ODN8039050
Side and curtain air bags
Side and curtain air bags are designed
to inflate when an impact is detected by
side collision sensors depending on the
severity of impact resulting from a side
impact collision.
Although the driver’s and front
passenger’s air bags are designed to
inflate only in frontal collisions, they also
may inflate in other types of collisions
if the front impact sensors detect a
sufficient impact. Side and curtain air
bags are designed to inflate only in side
impact collisions or rollover situations,
but they may inflate in other collisions
if the side impact sensors detect a
sufficient impact.
If the vehicle chassis is impacted by
bumps or objects on unimproved roads,
the air bags may deploy. Drive carefully
on unimproved roads or on surfaces not
designed for vehicle traffic to prevent
unintended air bag deployment.
Air bag non-inflation conditions
ODN8039051L
In certain low-speed collisions the air
bags may not deploy. The air bags are
designed not to deploy in such cases
because they may not provide benefits
beyond the protection of the seat belts.

Windshield Wipers
Operates as follows when the ignition
switch is in the ON position.
MIST: For a single wiping cycle, push
the lever upward and release. The
wipers will operate continuously if
the lever is held in this position.
OFF: Wiper is not in operation.
INT: Wiper operates intermittently at
the same wiping intervals. To vary
the speed setting, move the speed
control lever. The top most setting
will run the wipers most frequently
(for more rain). The bottom setting
will run the wipers the least
frequently (for less rain).
AUTO: The rain sensor located on the
upper end of the windshield glass
senses the amount of rainfall and
controls the wiping cycle for the
proper interval. The more it rains,
the faster the wiper operates.
When the rain stops, the wiper
stops. To vary the speed setting,
turn the speed control knob (B).
LO: The wiper runs at a lower speed.
HI: The wiper runs at a higher speed.
Information
If there is heavy accumulation of snow
or ice on the windshield, defrost the
windshield for about 10 minutes, or until
the snow and/or ice is removed before
using the windshield wipers to ensure
proper operation.
If you do not remove the snow and/or ice
before using the wiper and washer, it may
damage the wiper and washer system.
