Auxiliary battery (VAN/Truck)
The auxiliary battery is located in
engine room. (if equipped)
Keep the battery securely mount-ed.
Keep the battery top clean and dry.
Keep the terminals and connec- tions clean, tight, and coated with
petroleum jelly or terminal grease.
Rinse any spilled electrolyte from the battery immediately with a
solution of water and baking soda. Basically equipped battery is
maintenance free type. If your
vehicle is equipped with the bat-
tery marked with LOWER and
UPPER on the side, you can check
the electrolyte level. The elec-
trolyte level should be between
LOWER and UPPER. If the elec-
trolyte level is low, it needs to add
distilled (demineralized) water
(Never add sulfuric acid or other
electrolyte). When refill, be careful
not to splash the battery and adja-
cent components. And do not
overfill the battery cells. It can
cause corrosion on other parts.After then ensure that tighten the
cell caps. We recommend that you

on the case may cause battery
acid to leak, resulting in per-
sonal injury. Lift with a battery
carrier or with your hands on
opposite corners.
Never attempt to recharge the
battery when the battery
cables are connected.
The electrical ignition system
works with high voltage.
Never touch these compo-nents with the engine running
or the ignition switched on.
Failure to follow the abovewarnings can result in serious
bodily injury or death.
If you connect unauthorized
electronic devices to the bat-
tery, the battery may be dis-

4. Tire ply composition andmaterial
The number of layers or plies of rub-
ber-coated fabric are 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.
A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 3 fuse panels, one
located in the driver’s side panel bol-
ster, the other in the engine compart-
ment near the battery.
If any of your vehicle’s lights, acces-
sories, or controls do not work, check
the appropriate circuit fuse. If a fuse
has blown, the element inside thefuse will be melted.
