FIRE AND EXPLOSION
WARNING
Gasoline is highly flammable and gasoline
vapor is explosive. Never smoke while
working on vehicle. Keep all open flames
away from gasoline tank and lines. Wipe up
any spilled gasoline immediately.
Be careful when using gasoline. Do not use gasoline
to clean parts. Store only in approved containers away
from sources of heat or flame.
CELL PHONES
A driver's first responsibility is the safe operation of
the vehicle. The most important thing you can do
to prevent a crash is to avoid distractions and pay
attention to the road. Wait until it is safe to operate
Mobile Communication Equipment such as cell
phones, text messaging devices, pagers or two-way
radios.
VENTILATION
WARNING
Vehicle exhaust contains lethal fumes.
Breathing these fumes, even in low
concentrations, can cause death. Never
operate a vehicle in an enclosed area without
venting exhaust to the outside.
BATTERY SAFETY
CAUTION
Batteries normally produce explosive gases,
which can cause personal injury. Therefore,
do not allow flames, sparks or lit tobacco
to come near the battery. When charging or
working near a battery, always cover your
face and protect your eyes, and also provide
ventilation.
• Batteries contain sulfuric acid, which burns
skin, eyes and clothing.
• Disconnect the battery before removing or
replacing any electrical components.
