Hyundai Palisade: Air Bag - Advanced Supplemental Restraint
System / How Does the Air Bag System
Operate?
The SRS consists of the following
components:
1. Driver's front air bag module
2. Passenger's front air bag module
3. Side air bag modules
4. Curtain air bag modules
5. Retractor pre-tensioner
6. Air bag warning light
7. SRS control module (SRSCM)/
Rollover sensor
8. Front impact sensors
9. Side impact sensors
10.Side pressure sensors
11. Occupant classification system
12. Driver’s knee airbag module
The SRSCM (Supplemental Restraint
System Control Module) continually
monitors all SRS components while
the ignition switch is in the ON position
to determine if a crash impact is
severe enough to require air bag
deployment or pre-tensioner seat belt
deployment.
SRS warning light
The SRS (Supplement Restraint
System) air bag warning light on the
instrument panel displays the air bag
symbol depicted in the illustration.
The system checks the air bag electrical
system for malfunctions. The
light indicates that there is a potential
malfunction with your air bag system,
which could include your side and
curtain air bags used for rollover protection.
WARNING
If your SRS malfunctions, the air
bag may not inflate properly during
an accident increasing the
risk of serious injury or death.
If any of the following conditions
occur, your SRS is malfunctioning:
- The light does not turn on for
approximately six seconds
when the Engine Start/Stop
button is in the ON position.
- The light stays on after illuminating
for approximately six
seconds.
- The light comes on while the
vehicle is in motion.
- The light blinks when the
engine is running.
Have an authorized HYUNDAI
dealer inspect the SRS as soon
as possible if any of these conditions
occur.
During a frontal collision, sensors will
detect the vehicle's deceleration. If
the rate of deceleration is high
enough, the control unit will inflate
the front air bags.
The front air bags help protect the
driver and front passenger by
responding to frontal impacts in
which seat belts alone cannot provide
adequate restraint. When needed,
the side air bags help provide
protection in the event of a side
impact or rollover.
- Air bags are activated (able to
inflate if necessary) only when the
ignition switch is in the ON position.
- Air bags inflate in the event of certain
frontal or side collisions to
help protect the occupants from
serious physical injury.
- Generally, air bags are designed
to inflate based upon the severity
of a collision, its direction, etc.
These two factors determine
whether the sensors produce an
electronic deployment/inflation
signal.
- The front air bags will completely
inflate and deflate in an instant. It is
virtually impossible for you to see
the air bags inflate during an accident.
It is much more likely that you
will simply see the deflated air
bags hanging out of their storage
compartments after the collision.
- 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.
■ Driver's front air bag (1)
When the SRSCM detects a sufficiently
severe impact to the front of
the vehicle, it will automatically
deploy the front air bags.
■ Driver's front air bag (2)
Upon deployment, tear seams molded
directly into the pad covers will
separate under pressure from the
expansion of the air bags. Further
opening of the covers allows full
inflation of the air bags.
A fully inflated air bag, in combination
with a properly worn seat belt,
slows the driver or the front passenger
forward motion, reducing the risk
of head and chest injury.
■ Driver's front air bag (3)
■ Passenger's front air bag
After complete inflation, the air bag
immediately starts deflating, enabling
the driver to maintain forward visibility
and the ability to steer or operate
other controls.
WARNING
To prevent objects from becoming
dangerous projectiles when
the passenger's air bag inflates:
- Do not install or place any
objects (drink holder, CD
holder, stickers, etc.) on the
front passenger's panel above
the glove box where the passenger's
air bag is located.
- Do not install a container of
liquid air freshener near the
instrument cluster or on the
instrument panel surface.
Curtain air bags are located along
both sides of the roof rails above the
front and rear doors.
They are designed to help protect the
heads of the front seat occupants
and the rear outboard seat occupants
in certain side impact collisions...
After a frontal or side air bag inflates,
it will deflate very quickly. Air bag
inflation will not prevent the driver
from seeing out of the windshield or
being able to steer...

Description and operation
Description
The auto defogging sensor is installed on the front window glass. The sensor
judges and sends signal if moisture occurs to blow out wind for defogging. The
air conditioner control module receives signal from the sensor and restrains
moisture and eliminate defog by controlling the intake actuator, A/C, auto defogging
actuator, blower motor rpm, and mode actuator...
The Electronic Stability Control
(ESC) system helps to stabilize the
vehicle during cornering maneuvers.
ESC checks where you are steering
and where the vehicle is actually
going. ESC applies braking pressure
to any one of the vehicle's brakes
and intervenes in the engine management
system to assist the driver
with keeping the vehicle on the
intended path...
