¶¶ NOTE: The temperature must be
stabilized bef ore doing this
procedure.
To adjust the outside temperature
indicator, make sure the outside
temperature indicator is shown in
thedisplay,thenpressandholdthe
TRIP button f or 10 seconds (the
TRIP A or B is also reset). The
f ollowing sequence will appear f or 1
secondeach:0,1,2,3,4,5, 5, 4,
3, 2, 1, 0 (U.S.) or 0, 1, 2, 3,
3, 2, 1, 0 (Canada).
When it reaches the desired value,
release the TRIP button. You should
see the new outside temperature
displayed.
In certain weather conditions,
temperature readings near f reezing
(32°F, 0°C) could mean that ice is
f orming on the road surf ace.
This indicator displays the outside
temperature in Fahrenheit (U.S.
models) or Centigrade (Canadian
models).
The temperature sensor is in the
f ront bumper. Theref ore, the
temperature reading can be af f ected
by heat ref lection f rom the road
surf ace, engine heat, and the
exhaust f rom surrounding traf f ic.
This can cause an incorrect
temperature reading when your
speed is under 19 mph (30 km/h).
The sensor delays the indicator
update until it reaches the correct
outside temperature. This may take
several minutes.
If the outside temperature is
incorrectly displayed, you can adjust
it up to 5°F in U.S. models ( 3°C
in Canadian models) warmer or
cooler.
This shows the temperature of the
engine’s coolant. During normal
operation, the reading should be in
the middle of the gauge. In severe
driving conditions, such as very hot
weather or a long period of uphill
driving, the reading may reach near
the red mark. If it reaches the red
(Hot) mark, pull saf ely to the side of
the road. See page f or
instructions and precautions on
checking the engine’s cooling
system.

Look f or any obvious coolant leaks,
such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you f ind a leak, it
must be repaired bef ore you
continue driving (seeon page ).
If the temperature gauge stays at
the red mark, turn of f the engine.
If you do not see steam or spray,
leave the engine running and
watch the temperature gauge. If
the high heat is due to overloading,
the engine should start to cool
down almost immediately. If it
does, wait until the temperature
gauge comes down to the midpoint,
then continue driving.
If you see steam and/or spray
coming f rom under the hood, turn
of f the engine. Wait until you see
no more signs of steam or spray,
then open the hood.
Saf ely pull to the side of the road.
Put the transmission in neutral,
and set the parking brake. Turn
of f the all accessories, and turn on
the hazard warning indicators. If you don’t f ind an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark
(see on
page ).

If there was no coolant in the
reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the reading
reaches the middle of the
temperature gauge or lower
bef ore checking the radiator.Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the f irst stop. Af ter the
pressure releases, push down on
the cap, and turn it until it comes
off.Put the radiator cap back on
tightly. Run the engine, and check
the temperature gauge. If it goes
back to the red mark, the engine
needs repair (see
on page ).
If the temperature stays normal,
check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the
MAX mark. Put the cap back on
tightly.
Start the engine, and set the
temperature control dial to
maximum heat. Add coolant to the
radiator up to the base of the f iller
neck. If you do not have the
proper coolant mixture available,
you can add plain water.
Remember to have the cooling
system drained and ref illed with
the proper mixture as soon as you
can.
