Refueling dangers
Automotive fuels are flammable
materials. When refueling, please
note the following guidelines
carefully. Failure to follow these
guidelines may result in severe
personal injury, severe burns or
death by fire or explosion.
Read and follow all warning
posted at the gas station facil-
ity.
Before touching the fuel noz-
zle, you should eliminate
potentially dangerous static
electricity discharge by touch-
ing another metal part of the
vehicle, a safe distance away
from the fuel filler neck, noz-
zle, or other gas source.
Do not get back into a vehicle
once you have begun refueling
since you can generate static
electricity by touching, rubbing
or sliding against any item or
fabric (polyester, satin, nylon,
etc.) capable of producing stat-
ic electricity. Static electricity
discharge can ignite fuel
vapors resulting in rapid burn-
ing. If you must reenter the
vehicle, you should once again
eliminate potentially danger-
ous static electricity discharge
by touching a metal part of the
vehicle, away from the fuel filler
neck, nozzle or other gasoline
source.
Do not use cellular phones
while refueling. Electric current
and/or electronic interference
from cellular phones can
potentially ignite fuel vapors
causing a fire.
When refueling, always shut
the power off. Once refueling
is complete, check to make
sure the filler cap and filler
door are securely closed,
before starting the vehicle.
DO NOT use matches or a
lighter and DO NOT SMOKE or
leave a lit cigarette in your
vehicle while at a gas station
especially during refueling.
Automotive fuel is highly
flammable and can, when
ignited, result in fire.
If a fire breaks out during refu-
eling, leave the vicinity of the
vehicle, and immediately con-
tact the manager of the gas
station and then contact the
local fire department. Follow
any safety instructions they
provide.

Instrument Cluster Control
Adjusting instrument cluster
illumination
When the vehicle's position lights or
headlights are on, press the illumina-
tion control button to adjust the

speed of the vehicle and is calibrated
in miles per hour (MPH) and/or kilo-
meters per hour (km/h). Never adjust the instrument
cluster while driving. Doing so
could lead to driver distraction
which may cause an accident
and lead to vehicle damage,
serious injury, or death.
