conditioning on in stop−and−go traffic.
Towing a trailer.
NOTICE

Do not remove the thermostat in
the engine cooling system as this
may cause the engine to overheat.
The thermostat is designed to con-
trol the flow of coolant to keep the
temperature of the engine within
the specified operating range.
 Do not continue driving with an
overheated engine. See If your
vehicle overheats" on page 394 in
Section 4.CY15003
The tachometer indicates engine speed
in thousands of rpm (revolutions per
minute). Use it while driving to select
correct shift points and to prevent en-
gine lugging and over−revving.
Driving with the engine running too fast
causes excessive engine wear and poor
fuel economy. Remember, in most cases
the slower the engine speed, the greater
the fuel economy.
NOTICE
Do not let the indicator needle get
into the red zone. This may cause
severe engine damage.

NOTICE
This equipment has been tested and
found to comply with the limits for a
class B digital device, pursuant to
Part 15 of the FCC Rules. These lim-
its are designed to provide reasonable
protection against harmful interfer-
ence in a residential installation. This
equipment generates, uses and can
radiate radio frequency energy and, if
not installed and used in accordance
with the instructions, may cause
harmful interference to radio commu-
nications. However, there is no guar-
antee that interference will not occur
in a particular installation.
If this equipment does cause harmful
interference to radio or television re-
ception, which can be determined by
turning the equipment off and on, the
user is encouraged to try to correct
the interference by one or more of
the following measures:
Reorient or relocate the receiving
antenna.
Increase the separation between the
equipment and receiver.
Connect the equipment into an out-
let on a circuit different from that to
which the receiver is connected.
Consult the dealer or an experi-
enced radio/TV technician for help.CARING FOR YOUR COMPACT DISC
PLAYER, DVD PLAYER AND DISCS
Extremely high temperatures can keep
your compact disc player and DVD
player from working. On hot days, use
the air conditioning to cool the vehicle
interior before you use the players.
Bumpy roads or other vibrations may
make your compact disc player and
DVD player skip.
If moisture gets into your compact disc
player and DVD player, the players
may not play even though they appear
to be working. Remove the disc from
the player and wait until it dries.
CAUTION
Compact disc players and DVD play-
ers use an invisible laser beam which
could cause hazardous radiation ex-
posure if directed outside the unit. Be
sure to operate the players correctly.
