3. PRECAUTIONS
The warning lamp flashes and warning beep sounds when the ESP is operating
When the ESP operates during vehicle movement, the ESP warning lamp on the instrument panel
flashes and beep comes on every 0.1 second. The ESP system is only a supplementary device for
comfortable driving. When the vehicle exceeds its physical limits, it cannot be controlled.
Do not rely on the system. Keep on the safe driving.
Feeling when ESP is working
When the ESP system activates, the feeling can be different depending on vehicle driving conditions.
For example, you will feel differently when the ESP system is activated during the ABS is operating
with the brakes applied and when the brakes are not applied on a curve.
If the ESP system operates when the brake is applied, the brake pressure will be increased on the
corresponding wheel which already has braking pressure for the ESP controls.
ARP Operation
During the ARP operation, vehicle safety (rollover prevention) takes the first priority and thus,
stronger engine control is in effect. Consequently, the vehicle speed decreases rapidly, so the driver
must take caution for the vehicle may drift away from the lane.
Noise and vibration that driver feels when ESP system is operating
The ESP system may transfer noise and vibration to the driver due to the pressure changes caused
by the motor and valve operations in a very short period of time. And, keep in mind that the output
and vehicle speed could be decreased without rpm increase due to the ASR function that controls
the engine power.

Circuit description
When compared to the vehicle equipped with ABS/EBD only, the internal hydraulic circuit has a
normally-open separation valve and a shuttle valve in primary circuit and in secondary circuit.
When the vehicle brakes are not applied during engine running or when applying the non-ABS operating
brakes, the normally-open separation valve and the inlet valve are open, whereas the normally-closed
shuttle valve and the outlet valve are closed.
When the ESP system is operating, the normally-open separation valve will be closed by the solenoid
valve operation and the hydraulic circuit will be established by the shuttle valve. Then, the inlet and outlet
valves will be closed or open depending on the braking pressure RISE, HOLD or DUMP conditions.
Flashing warning lamp and warning sound during ESP operation
When the ESP operates while the vehicle is moving, the ESP warning lamp on the instrument panel
flickers and the buzzer sounds at every 0.1 second. The ESP lamp operation is to inform a driver that the
vehicle is extremely unstable.
The ESP system is just a supplementary system for the vehicle and it cannot control the vehicle over the
physical limit. Do not solely rely on the system but be advised to drive the vehicle safely.
Drive feeling during ESP operation
When the ESP system activates, the driving feeling can be different depending on vehicle driving
conditions. For example, it will feel different when the ESP system is activated while the ABS is operated
by depressing the brake pedal and when the ESP system is in control without the brake pedal
depressed on the same curve.
If the ESP system operates with the brake applied, the brake pressure will be increased on the
corresponding wheel which already has braking pressure for the ESP controls. In other words, the ESP
system would make the driver feel more abruptly braked compared to the situation that the braking
pressure is applied to wheel which had no braking force.
Noise and vibration that driver senses during ESP operation
The ESP system may transfer noise and vibration to a driver due to the pressure changes caused by the
motor and valve operations in a very short period of time.
Extreme cornering will trigger the ESP operation and this will make the driver sense noise and vibration
due to sudden brake application.
Also, the ESP system controls the engine power. Therefore, the driver may notice the engine power
decreases even when the accelerator pedal is depressed.

1. OVERVIEW
A radial tire uses a cord angle of 90 degrees. That is, the cord material runs in a radial or direct line from
one bead to the other across the tread. In addition, a radial tire has a belt overwrap under the tread
surface to provide greater structural stability. The belt overwrap of a radial tire distortion while the radial
structure enables high speed driving.
Tire supports the weight of the vehicle, reduces the impact from the road and at the same time,
transmits the power to propel, brake and steer on the road. It also functions to maintain a
vessel of air.
There is wear limit mark on the tire, which protrudes as a strip shape located approximately 1.6 mm from
mark on the shoulder to let the driver find the wear mark easily. To measure the tire groove depth,
measure at any point other than the point which has a wear limit mark.
The tire is worn unevenly according to the driver's driving habit, improper servicing, low tire inflation
pressure, changed tire location, etc.
1) Structure of Tire
Tread
This thick layer of rubber provides the interface
between the tire and the road. Wear-resistant
rubber is used to protect the carcass and belt
against fractures and impacts and to deliver a
long driving life.
Shoulder
Located between the tread and sidewall, the
shoulder rubber is the thickest so that the design
must allow for the easy diffusion of heat
generated within the tire while driving.
Sidewall
The part between the shoulder and bead, the
flexible sidewall protects the carcass and
structure, pattern, manufacturing company,
product name and various characters are
indicated here. Bead
The bead attaches the tire to the rim and wraps
the end of the cord fabric. Comprised of the bead
wire, core, flipper and other parts, the bead is
generally designed to be slightly tight around the
rim so that in the case of a sudden drop in inflation
pressure, the tire will not fall off the rim.
Carcass
As the most important framework of a tire, the
entire inner layer of cord fabric is called the
carcass. The carcass acts to support air pressure,
vertical load and absorb shocks.

5. LOW TIRE PRESSURE WARNING
If the tire pressure is less than 13% of the proper value calculated by the TPMS ECU depending on the
ambient temperature for more than 8 minutes, the 1st low tire pressure warning is given. And, if the tire
pressure is less than 20% for more than 4 minutes, the 2nd warning is given. At this time, the "Check
tire" message is displayed on the DOT LCD display and the global warning lamp comes on.
ECU receives the ambient temperature signal from the instrument cluster through CAN
communication and calculates the proper tire pressure to correct it since the tire pressure changes
depending on the ambient temperature.

7. TIRE INFLATION PROCEDURE FOR VEHICLE WITH TPMS
1) Overview
For the vehicle with TPMS, the tire should be inflated in a method different from the conventional method
since the tire pressure values displayed on the tire pressure gauge and instrument cluster are different
after inflation.
The tire pressure displayed on the instrument cluster should be checked after a certain time delay
(wireless transmission time for wheel module).
The displayed value can be changed after driving even if it was set to the specified value.
2) Tire Inflation Procedure
Park the vehicle on a flat ground and let everyone get off the vehicle. A.
This symptom is occurred as the inflation pressure displayed on the instrument cluster becomes
different by tires as different load is applied to each tire due to driving condition, number of
occupants, irregular temperature change in tire and load condition.
If there is another vehicle equipped with the TPMS, keep the distance from this vehicle for at
least 5 mm to prevent interference of wheel module transmission.
Unload cargoes if they are usually not loaded during driving.
The instrument cluster does not display every pressure change while the air is injected or
discharged to/from the tire. This is because the wheel module sends the pressure value to the
TPMS ECU every minute.
In addition, if there are other vehicles with the TPMS nearby, it might take several minutes to
display the pressure values due to radio jamming and weather condition. -
