CLIMATE CONTROL AIR FILTER (IF EQUIPPED)
Filter inspection
The climate control air filter should
be replaced according to the
Maintenance Schedule. If the vehicle
is operated in severely air-polluted
cities or on dusty rough roads for a
long period, it should be inspected
more frequently and replaced earlier.
When you replace the climate control
air filter, replace it performing the fol-
lowing procedure, and be careful to
avoid damaging other components.
1. Open the glove box and remove
the stoppers on both sides.2. With the glove box open, pull the
support strap (1).

3. Remove the climate control air fil-
ter cover while pressing the lock
on both sides of the cover.4. Replace the climate control air fil-
ter.
5. Reassemble in the reverse order
of disassembly.
When replacing the climate control
air filter install it properly. Otherwise,
the system may produce noise and
the effectiveness of the filter may be
reduced.

Maintenance
When recharging the battery,
observe the following precautions:
The battery must be removed from
the vehicle and placed in an area
with good ventilation.
Do not allow cigarettes, sparks, or
flame near the battery.
Watch the battery during charging,
and stop or reduce the charging
rate if the battery cells begin
gassing (boiling) violently or if the
temperature of the electrolyte of
any cell exceeds 49°C (120°F).
Wear eye protection when check-
ing the battery during charging.
Disconnect the battery charger in
the following order.
1. Turn off the battery charger main
switch.
2. Unhook the negative clamp from
the negative battery terminal.
3. Unhook the positive clamp from
the positive battery terminal. Before performing maintenance or
recharging the battery, turn off all
accessories and stop the engine.
The negative battery cable must be
removed first and installed last
when the battery is disconnected.Reset items
The following items should be reset
after the battery has been dis-
charged or the battery has been dis-
connected.

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 per-
missible 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:
Treadwear 200
Traction AA
Temperature A Tread wear
The tread wear grade is a compara-
tive rating based on the wear rate of
the 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.
Tires degrade over time, even when
they are not being used. Regardless
of the remaining tread, we recom-
mend that tires be replaced after
approximately six (6) years of normal
service. Heat caused by hot climates
or frequent high loading conditions
can accelerate the aging process.
These grades are molded on the
side-walls of passenger vehicle tires.
The tires available as standard or
optional equipment on your vehicles
may vary with respect to grade.
