{Warning
When the engine coolant is still
hot, do not remove the radiator
cap. Hot vapor will come out and
you may be scalded. Add engine
coolant only when the engine
coolant temperature has dropped.
If this light comes on and stays on
while you are driving, your engine
coolant might have overheated
and your engine may be too hot.
You should pull off the road, stop
your vehicle and take appropriate
actions for engine overheating.

Radio Reception
Usually, a problem with radio
reception does not mean there is a
problem with your radio - it is just the normal result of conditions
outside the vehicle. For example,
nearby buildings and terrain can
interfere with FM reception. Power
lines or telephone wires can
interfere with AM signals.
And of course, radio signals have a
limited range. The farther you are
from a station, the weaker its signal
will be. In addition, reception
conditions change constantly as
your vehicle moves.
Here are some common reception
problems that probably do not
indicate a problem with your radio.
FM Transmissions
Fading and drifting stations -
Generally, the effective range of FM
is about 40 km (25 miles). Once
outside this range, you may notice
fading and drifting, which increase
with the distance from the radio
transmitter. They are often
accompanied by distortion.
Multi-path - FM signals are
reflective, making it possible for two
signals to reach your antenna at the
same time. If this happens, the
signals will cancel each other out,
causing a momentary flutter or loss
of reception.
Static and fluttering - These occur
when signals are blocked by
buildings, trees, or other large
objects. Increasing the bass level
may reduce static and fluttering.
Station swapping - If the FM signal
you are listening to is interrupted or
weakened, and there is another
strong station nearby on the FM
band, your radio may tune in the
second station until the original
signal can be picked up again.
AM Transmissions
Fading - AM broadcasts are
reflected by the upper atmosphere -
especially at night. These reflected
signals can interfere with those
received directly from the radio
station, causing the radio station to
sound alternately strong and weak.
Station interference - When a
reflected signal and a signal
received directly from a radio station
are very nearly the same frequency,
