Maintenance
Checking the washer fluid level
OBI3090038OBI3090038
Check the fluid level in the washer fluid
reservoir and add fluid if necessary. Plain
water may be used if washer fluid is not
available.
However, use washer solvent with
antifreeze characteristics in cold
climates to prevent freezing.
WARNING
Coolant
• Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
• Radiator coolant can severely
obscure visibility when sprayed on
the windshield and may cause loss
of vehicle control or damage to the
paint and body trim.
• Windshield washer fluid agents
contain some amounts of alcohol
and can be flammable under certain
circumstances. Do not allow sparks
or flame come in contact with the
washer fluid or the washer fluid
reservoir. Damage to the vehicle or
occupants could occur.
• Windshield washer fluid is poisonous
to humans and animals. Do not drink
and avoid coming in contact with
the windshield washer fluid. Serious
injury or death could occur.

Filter inspection
If the vehicle is operated in the severely
air-polluted cities or on dusty rough
roads for a long period, it should be
inspected more frequently and replaced
earlier. When you, the owner, replace
the climate control air filter, replace it
performing the following procedure,
and be careful to avoid damaging other
components.
Replace the filter according to the
maintenance Schedule.

2. Push in both sides of the glove box as
shown. This will ensure that the glove
box stopper pins will get released
from its holding location allowing the
glove box to hang.

NOTICE
Install a new climate control air filter
in the correct direction with the arrow
symbol () facing downwards.
Otherwise, the climate control effects
may decrease, possibly with a noise.

Wheel size designation
Wheels are also marked with important
information that you need if you ever
have to replace one. The following
explains what the letters and numbers in
the wheel size designation mean.
Example wheel size designation:
5.0JX14
5.0 - Rim width in inches.
J - Rim contour designation.
14 - Rim diameter in inches
Tire speed ratings
The chart below lists many of the
different 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 operating speed.
Speed Rating
SymbolMaximum Speed
S180 km/h (112 mph)
T190 km/h (118 mph)
H 210 km/h (130 mph)
V 240 km/h (149 mph)
W 270 km/h (168 mph)
Y 300 km/h (186 mph)

3. Checking tire life (TIN : Tire
Identification Number)
Any tires that are over 6 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 numbers
on a tire consisting of numbers and
English letters. The manufacturing 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 numbers indicate week
and year manufactured.
For example:
DOT XXXX XXXX 2220 represents that
the tire was produced in the 22th week
of 2020.
WARNING
Tire age
Tires degrade over time, even when
they are not being used.
Regardless of the remaining tread, it is
recommended that tires generally be
replaced after six (6) years of normal
service. Heat caused by hot climates
or frequent high loading conditions can
accelerate the aging process. Failure to
follow this warning could cause sudden
tire failure, which could lead to a loss
of control and an accident involving
serious injury or death.

4. Tire ply composition and material
The number of layers or plies of
rubber-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 construction; the
letter “D” means diagonal or bias ply
construction; and the letter “B” means
belted-bias ply construction.
5. Maximum permissible inflation
pressure
This number is the greatest amount
of 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 maximum chapter
width.
For example:
TREAD wear 200
TRACTION AA
TEMPERATURE A
Tread wear
The tread wear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would
wear one-and-a-half times (1½) as well
on the government 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 side-
walls of passenger vehicle tires. The
tires available as standard or optional
equipment on your vehicle may vary
with respect to grade.
