The
gauge
indicates
the
engine
coolant
temperature
when
the
engine
switch
is
on.
The
engine
operating
temperature
will
vary
with
changes
in
weather
and
engine
load.
If
the
needle points to
the
red zone or
higher, stop your vehicle and
allow
the
engine to cool.
Your vehicle may overheat during
severe
operating conditions, such as:
• Driving up a long hill on a
hot
day.
• Reducing speed or stopping after high
speed driving.
• Idling
for
a long period with
the
air
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
ve-
hicle
overheats"
on

Tachometer
(on
some
models)
16H008
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.
