2) Operation of ESP System
The ESP (Electronic Stability Program) has been developed to help a driver avoid danger of losing
control of the vehicle stability due to understeer or oversteer during cornering. The yaw rate sensor,
lateral sensor and longitudinal sensor in the sensor cluster and the steering wheel angle sensor under
the steering column detect the vehicle conditions when the inner or outer wheels are spinning during
oversteer, understeer or cornering. The ESP ECU controls against oversteer or understeer during
cornering by controlling the vehicle stability using input values from these sensors and applying the
braking force to the corresponding wheels independently. The system also controls the engine power
right before the wheel spin synchronized with the ASR function to decelerate the vehicle automatically in
order to maintain the vehicle stable during cornering.
(1) Under steering
What is understeering? ▶
Understeer is a term for a condition in which the steering wheel is steered to a certain angle during driving
and the front tires slip toward the reverse direction of the desired direction. Generally, vehicles are
designed to have understeer. It is because that the vehicle can return back to inside of cornering line
when the steering wheel is steered toward the inside even when the front wheels are slipped outward.
As the centrifugal force increases, the tires can easily lose the traction and the vehicle tends to slip
outward when the curve angle gets bigger and the speed increases.

ESP controls during understeer ▶
The ESP system recognizes the directional angle with the steering wheel angle sensor and senses the
slipping route that occurs reversely against the vehicle cornering direction during understeer with the ya
w
rate sensor and lateral sensor. Then, the ESP system applies the braking force to the rear inner wheel to
compensate the yaw moment value. In this way, the vehicle does not lose its driving direction and the
driver can steer the vehicle as intended.
(2) Over steering
What is oversteering? ▶
Oversteer is a term of a condition in which the steering wheel is steered to a certain angle during driving
and the rear tires slip outward losing traction.
Compared to understeering vehicles, it is hard to control the vehicle during cornering and the vehicle can
spin due to rear wheel moment when the rear tires lose traction and the vehicle speed increases.
ESP controls during oversteer ▶
The ESP system recognizes the directional angle with the steering wheel angle sensor and senses the
slipping route that occurs towards the vehicle cornering direction during oversteer with the yaw rate
sensor and lateral sensor. Then the ESP system applies the braking force to the front outer wheel to
compensate the yaw moment value. In this way, the vehicle does not lose its driving direction and the
driver can steer the vehicle as intended.

As the air bag system is very hot after being deployed, allow at least 30 minutes for the system to cool
down sufficiently before touching it. It can cause serious burns.
When an occupant fastens the seat belt in an unstable or inclined posture, the air bag system cannot
protect the occupant properly. Moreover, the occupant can be injured by the air bag.
Children and infants should ride in a rear seat. Seating in the passenger's seat with carrying a child or
infant is strictly prohibited. An infant or a child could be severely injured by air bag deployed.
A child restraint system must be placed in a rear seat.
A child restraint system must not be placed in the passenger's seat. An infant or a child could be
severely injured by the air bag deployment.
Do not cover, place any object or affix any stickers on the air bag inflation location.
Do not cover the front seat. The side air bag will not work properly.
Never put your arms around the front seat from behind, lean on the front seatback, or put your arms
out of the window. You can severely injured when the side air bag deploys.
Never lean on the door since it becomes very dangerous when the side air bag deploys.
Do not put any object such as an umbrella or bags between the door and side air bag mounting.
The side air bag deploys when there is a severe side collision.
Do not put any object such as an umbrella or bags between the door and side air bag mounting.
Do not slam the front door to close it. The side air bag may deploy unexpectedly.
Do not move your seat too close to the steering wheel or dashboard. Being too close to the steering
wheel or instrument panel during the air bag deployment could cause serious injury, including death
Move back as far as practical to allow the air bag room to inflate when driving.
Do not incline toward the steering wheel or hold the steering wheel with your hands crossed. Never
allow the front passenger to put hands or feet on the dash board. It can cause severe injures when
the air bag inflates.
Never put your feet on the dash board. You can severely injured when the air bag inflates.
It is normal that a loud noise, dust and smoke occur when the air bag and seat belt pretensioner
operate.
A large quantity of non-toxic gas is generated when the air bag or seat belt pretensioner deploys. If
these airborne particles irritate your skin, eyes, nose, or throat, rinse the area with cool water. If the
irritation continues, see your doctor.
The windshield glass may be broken when the passenger air bag deploys.
The air bag is a unit to save an occupant's life from sudden accident and it inflates at a very fast speed
by gas with high temperature, which might cause injury, such as an abrasion, bruise and burn
depending on the accident conditions.
A loud noise and non-toxic smoke-like particles are generated when air bags deploy. -
