Detecting sensor
The rear radars are the sensors
inside the rear bumper for detecting
the side and rear areas. Always keep
the rear bumper clean for proper
operation of the system.
The driver should always use
extreme caution while operat-
ing the vehicle, whether or notthe warning light on the out-
side rearview mirror illumi-nates or there is a warningalarm.
Playing the vehicle audio sys-
tem at high volume may offsetthe Blind-Spot Collision
Warning system warningsounds.
If any other warning sound
such as seat belt warning
chime is already generated,the Blind-Spot Collision
Warning (BCW) system warn-
ing may not sound.
CAUTION
OAD058031N
The system may not work
properly when the bumper
has been damaged, or if the
rear bumper has beenreplaced or repaired.
The sensing range differs
somewhat according to the
width of the road. When the
road is narrow, the system
may detect other vehicles in
the next lane.
The system may turn off due
to strong electromagnetic
waves.
Always keep the sensors
clean.
NEVER arbitrarily disassem-
ble the sensor component nor
apply any impact on the sen-sor component.

Compact spare tire replacement
A compact spare tire has a shorter
tread life than a regular size tire.
Replace it when you can see the
tread wear indicator bars on the tire.The replacement compact spare tire
should be the same size and design
tire as the one provided with your
new vehicle and should be mountedon the same compact spare tire
wheel. The compact spare tire is notdesigned to be mounted on a regular
size wheel, and the compact spare
tire wheel is not designed for mount-
ing a regular size tire.
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 widthand offset.
Tire Traction
Tire traction can be reduced if you
drive on worn tires, tires that are
improperly inflated or on slippery
road surfaces. Tires should bereplaced when the tread depth is at
least 1.6 mm (2/32 inch). To reduce
the possibility of losing control, slow
down whenever there is rain, snow orice on the road.
When replacing tires (or
wheels), it is recommended to
replace the two front or two
rear tires (or wheels) as a pair.Replacing just one tire can
seriously affect your vehicle'shandling.
Heat caused by hot climates or frequent high loading con-ditions can accelerate the
aging process. Failure to fol-
low this warning may cause
sudden tire failure, which
could lead to a loss of vehicle
control resulting in an acci-dent.
The original tire should be repaired or replaced as soon as
possible to avoid failure of the
spare and loss of vehicle con-
trol resulting in an accident. The
compact spare tire is for emer-
gency use only. Do not operate
your vehicle over 80 km/h (50mph) when using the compact
spare tire.

Tire Maintenance
In addition to proper inflation, correct wheel alignment helps to decrease
tire wear. If you find a tire is worn
unevenly, have your dealer check thewheel alignment.
When you have new tires installed,
make sure they are balanced. This
will increase vehicle ride comfort and
tire life. Additionally, a tire should
always be rebalanced if it is removedfrom the wheel.
Tire Sidewall Labeling
This information identifies and
describes the fundamental charac-
teristics of the tire and also provides
the tire identification number (TIN)
for safety standard certification. TheTIN can be used to identify the tire incase of a recall.
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 designationmean.Example tire size designation:
(These numbers are provided as an
example only; your tire size designa-
tor could vary depending on your
vehicle.) 205/55R16 91H
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.
91 - 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:6.5J X 16
6.5 - 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 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.
3. Checking tire life (TIN : TireIdentification Number)
Any tires that are over six years old,
based on the manufacturing date,(including the spare tire) should be
replaced by new ones. You can find
the manufacturing date on the tire
sidewall (possibly on the inside of the
wheel), displaying the DOT Code.
The DOT Code is a series of num-
bers on a tire consisting of numbers
and English letters. The manufactur-
ing date is designated by the last four
digits (characters) of the DOT code.
DOT : XXXX XXXX OOOO
The front part of the DOT means a
plant code number, tire size and
tread pattern and the last four num-
bers indicate week and year manu-
factured.
For example:
DOT XXXX XXXX 1418 represents
that the tire was produced in the 14th
week of 2018.

4. Tire ply composition andmaterial
The number of layers or plies of rub-
ber-coated fabric in the tire. Tire
manufacturers also must indicate the
materials in the tire, which include
steel, nylon, polyester, and others.
The letter "R" means radial ply con-
struction; the letter "D" means diago-
nal or bias ply construction; and theletter "B" means belted-bias ply con-
struction.
5. Maximum permissible infla-tion pressure
This number is the greatest amountof air pressure that should be put in
the tire. Do not exceed the maximum
permissible inflation pressure. Refer
to the Tire and Loading Information
label for recommended inflation
pressure.
6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that
can be carried by the tire. When
replacing the tires on the vehicle,
always use a tire that has the same
load rating as the factory installed
tire.
7. Uniform tire quality grading
Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and maxi-
mum section width.
For example:
TREAD WEAR 200
TRACTION AA
TEMPERATURE A
Tread wear
The tread wear grade is a compara-
tive rating based on the wear rate ofthe tire when tested under controlled
conditions on a specified govern-
ment test course. For example, a tire
graded 150 would wear one-and-a-
half times (1½) as well on the gov-
ernment course as a tire graded 100.
The relative performance of tires depends upon the actual conditions
of their use, however, and may
depart significantly from the norm
due to variations in driving habits,
service practices and differences in
road characteristics and climate.
These grades are molded on the
sidewalls of passenger vehicle tires.
The tires available as standard or
optional equipment on your vehicle
may vary with respect to grade.

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 accessories. Some exam-
ples of optional accessories are
automatic transmission, power
seats, and air conditioning.
Aspect Ratio
The relationship of a tire's height toits 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 thetread.
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 TireIdentification Number (TIN), an
alphanumeric designator which can
also identify the tire manufacturer,
production plant, brand and date ofproduction.
