Driving your vehicle
Limitations of the System
The driver must be cautious in the
below situations because the system
may not detect other vehicles or
objects in certain circumstances:
When a trailer or carrier isinstalled.
The vehicle drives in inclement weather such as heavy rain or snow.
The sensor is polluted with rain, snow, mud, etc.
The rear bumper where the sensor is located is covered with a foreign
object such as a bumper sticker, a
bumper guard, a bike rack, etc.
The rear bumper is damaged, or the sensor is out of the original
default position.
The vehicle height gets lower or higher due to heavy loading in a
trunk, abnormal tire pressure, etc.
When the temperature of the rear bumper is high.
When the sensors are blocked by other vehicles, walls or parking-lot
pillars.
The vehicle drives on a curved road.
The road pavement (or the periph- eral ground) abnormally contains
metallic components (i.e. possibly
due to subway construction).
There is a fixed object near the vehicle, such as a guardrail.
While going down or up a steep road where the height of the lane is
different.
Driving on a narrow road where trees or grass or overgrown.
Driving in rural areas where the sensor does not detect another
vehicle for an extended period of
time. Driving on a wet road.
Driving on a road where the guardrail
or wall is in double structure.
A big vehicle is near such as a bus or truck.
When the other vehicle approach- es very close.
When the other vehicle passes at a very fast speed.
While changing lanes.
If the vehicle has started at the same time as the vehicle next to
you and has accelerated.
When the vehicle in the next lane moves two lanes away from you OR
when the vehicle two lanes away
moves to the next lane from you.
A motorcycle or bicycle is near.
A flat trailer is near.
If there are small objects in the detecting area such as a shopping
cart or a baby stroller.
If there is a low height vehicle such as a sports car.
The brake pedal is depressed.
ESC (Electronic Stability Control) is activated.
ESC (Electronic Stability Control) malfunctions.
The tire pressure is low or a tire is damaged.
The brake is reworked.
The vehicle sharply stops.
Temperature is extremely low around the vehicle.
The vehicle severely vibrates while driving over an uneven/bumpy road,
or concrete patch.
The vehicle drives on a slippery surface due to snow, water puddle,
or ice.

Driving your vehicle
Your vehicle may accelerate when a vehicle ahead of you disappears.
When you are warned that the vehicle ahead of you is not detect-
ed, drive with caution.
When driving in stop-and-go traffic, and a vehicle in front of you
merges out of the lane, the system
may not immediately detect the
new vehicle that is now in front of
you. In this case, you must main-
tain a safe braking distance, and if
necessary, depress the brake
pedal to reduce your driving speed
in order to maintain a safe dis-
tance. Always look out for pedestrians
when your vehicle is maintaining a
distance with the vehicle ahead.
Always be cautious for vehicles with higher height or vehicles car-
rying loads that sticks out from the
back of the vehicle.

1. Manufacturer or brand name
Manufacturer or brand name is
shown.
2. Tire size designation
A tire’s sidewall is marked with a tire
size designation. You will need this
information when selecting replace-
ment tires for your car. The following
explains what the letters and num-
bers in the tire size designation
mean.
Example tire size designation:
(These numbers are provided as an
example only; your tire size designa-
tor could vary depending on your
vehicle.)
245/45 R19 98W
245 - Tire width in millimeters.
45 - Aspect ratio. The tire’s section
height as a percentage of its
width.
R - Tire construction code (Radial).
19 - Rim diameter in inches.
98 - Load Index, a numerical code associated with the maximum
load the tire can carry.
W - Speed Rating Symbol. See the speed rating chart in this section
for additional information.
Wheel size designation
Wheels are also marked with impor-
tant information that you need if you
ever have to replace one. The follow-
ing explains what the letters and
numbers in the wheel size designa-
tion mean.
Example wheel size designation:
8.5J X 19
8.5 - Rim width in inches.
J - Rim contour designation.
19 - Rim diameter in inches.
Tire speed ratings
The chart below lists many of the dif-
ferent speed ratings currently being
used for passenger car tires. The
speed rating is part of the tire size
designation on the sidewall of the
tire. This symbol corresponds to that
tire’s designed maximum safe oper-
ating speed.

W 168 mph (270 km/h)
Y186 mph (300 km/h)

Maintenance
Temperature - A, B & C
The temperature grades are A (the
highest), B and C representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. Grade C
responds to a level of performance
which all passenger car tires must
meet under the Federal Motor
Vehicle Safety Standard No. 109.
Grades B and A represent higher
levels of performance on the labora-
tory test wheel than the minimum
required by law.
Tire Terminology and
Definitions
Air Pressure
The amount of air inside the tire
pressing outward on the tire. Air
pressure is expressed in pounds per
square inch (psi) or kilopascal (kPa).
Accessory Weight
This means the combined weight of
optional accessories. Some exam-
ples of optional accessories are
automatic transmission, power
seats, and air conditioning.
Aspect Ratio
The relationship of a tire's height to
its width.
Belt
A rubber coated layer of cords that is
located between the plies and the
tread. Cords may be made from steel
or other reinforcing materials.
Bead
The tire bead contains steel wires
wrapped by steel cords that hold the
tire onto the rim.
Bias Ply Tire
A pneumatic tire in which the plies
are laid at alternate angles less than
90 degrees to the centerline of the
tread.
The temperature grade for this
tire is established for a tire that
is properly inflated and not
overloaded. Excessive speed,
under-inflation, over-inflation,
or excessive loading, either
separately or in combination,
can cause heat build-up and
possible sudden tire failure.
This may cause loss of vehicle
control resulting in an accident.
