WARNING- Driving under
the influence of alcohol or
drugs
Drinking and driving is dangerous.
Drunk driving is the number one
contributor to the highway death
toll each year. Even a small amount
of alcohol will affect your reflexes,
perceptions and judgment. Driving
while under the influence of drugs
is as dangerous or more dangerous
than driving drunk.
You are much more likely to have a
serious accident if you drink or
take drugs and drive.
If you are drinking or taking drugs,
don’t drive. Do not ride with a driv-
er who has been drinking or taking
drugs. Choose a designated driver
or call a cab.
WARNING
All passengers must be properly
belted whenever the vehicle is mov-
ing. Refer to “Seat belts” in section
3 for more information on their
proper use.
WARNING
Always check the surrounding
areas near your vehicle for people,
especially children, before putting a
car into D (Drive) or R (Reverse).
WARNING
When you intend to park or stop
the vehicle with the engine on, be
careful not to depress the accel-
erator pedal for a long period of
time. It may overheat the engine
or exhaust system and cause fire.
When you make a sudden stop or turn the steering wheel rapidly,
loose objects may drop on the
floor and it could interfere with
the operation of the foot pedals,
possibly causing an accident.
Keep all things in the vehicle
safely stored.
If you do not focus on driving, it may cause an accident. Be care-
ful when operating what may dis-
turb driving such as audio or
heater. It is the responsibility of
the driver to always drive safely.
