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 vehicle abruptly changes driv- ing direction. The vehicle makes sharp lane
changes.
The vehicle sharply stops.
Temperature is extremely low around the vehicle.
The vehicle severely vibrates while driving over a an uneven/bumpy
road, or concrete patch.
The vehicle drives on a slippery surface due to snow, water puddle,
or ice.
The vehicle is driven near areas containing metal substances such
as a construction zone, railroad, etc.
When the surrounding vehicle or structure is driving in a wide area
(desert, field, suburb etc.) The BCW indicator on the outer side
view mirror may not illuminate prop-
erly when:
The outside rearview mirror hous-
ing is damaged
The mirror is covered with dirt, snow, or debris.
The window is covered with dirt, snow, or debris.
The window is tinted.

Driving on a slope
The BCW system may not operate
properly when driving on a slope. In
certain instances the system may not
detect the vehicle in the next lane.
Also, in certain instances the system
may wrongly recognize the ground or
structures.
Always pay attention to road and
driving conditions while driving. Driving where the heights of the
lanes are different
The BCW system may not operate
properly when driving where the
heights of the lanes are different.
In certain instances, the system may
not detect the vehicle on a road with
different lane heights (underpass
joining section, grade separated
intersections, etc.).
Always pay attention to road and
driving conditions, while driving.[A] : noise barrier, [B] : guardrail
Driving where there is a structure beside the road
The BCW system may not operate
properly when driving where there is
structure beside the road.
In certain instances, the system may
wrongly recognize the structures
(noise barriers, guardrail, double
guardrail, median strip, bollard,
street light, road sign, tunnel wall,
etc.) beside the road.
Always pay attention to road and
driving conditions, while driving.

Tire replacement
If the tire is worn evenly, a tread wear
Indicator (A) will appear as a solid
band across the tread. This shows
there is less than 1.6 mm (1/16 inch)
of tread left on the tire. Replace the
tire when this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tire.The ABS works by comparing the
speed of the wheels. The tire size
affects wheel speed. When replacing
tires, all 4 tires must use the same
size originally supplied with the vehi-
cle. Using tires of a different size can
cause the ABS (Anti-lock Brake
System) and ESC (Electronic
Stability Control) to work irregularly.
✽ ✽

NOTICE
We recommend that when replacing
tires, use the same which were origi-
nally supplied with the vehicle. If
not, driving performance could be
altered.
Wheel replacement
When replacing the metal wheels for
any reason, make sure the new
wheels are equivalent to the original
factory units in diameter, rim width
and offset.
A wheel that is not the correct size
may adversely affect wheel and
bearing life, braking and stopping
abilities, handling characteristics,
ground clearance, body-to-tire clear-
ance, snow chain clearance,
speedometer and odometer calibra-
tion, headlight aim and bumper
height.

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.)
P205/55R16 89H
P - Applicable vehicle type (tiresmarked with the prefix “P’’ are
intended for use on passenger
vehicles or light trucks; however,
not all tires have this marking).
205 - Tire width in millimeters.
55 - Aspect ratio. The tire’s section height as a percentage of its
width.
R - Tire construction code (Radial).
16 - Rim diameter in inches. 89 - Load Index, a numerical code
associated with the maximum
load the tire can carry.
H - 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:
6.0JX16
6.0 - Rim width in inches.
J - Rim contour designation.
16 - Rim diameter in inches. Tire speed ratings
The chart below lists many of the dif-
ferent speed ratings currently being
used for passenger vehicles. 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.
S 180 km/h (112 mph)
T 190 km/h (118 mph)
H 210 km/h (130 mph) V 240 km/h (149 mph)Z Above 240 km/h (149 mph)

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. Grades B and A
represent higher levels of perform-
ance on the laboratory 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
kilopascal (kPa) or pounds per
square inch (psi).
Accessory Weight: This means the
combined weight of optional acces-
sories. Some examples of optional
accessories are, automatic transmis-
sion, power seats, and air condition-
ing.
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. Cold Tire Pressure:
The amount of
air pressure in a tire, measured in
kilopascals (kPa) or pounds per
square inch (psi) before a tire has
built up heat from driving.
Curb Weight: This means the weight
of a motor vehicle with standard and
optional equipment including the
maximum capacity of fuel, oil and
coolant, but without passengers and
cargo.
DOT Markings: The DOT code
includes the Tire Identification
Number (TIN), an alphanumeric des-
ignator which can also identify the
tire manufacturer, production plant,
brand and date of production.
