2007 HONDA RIDGELINE coolant temperature

¶¶µµ
µµµ
µµµ
This
indicator displays the outside
temperature in Fah renheit (U.S.
models) or Cen tigrade (Canadian
models).
The temperature sensor is in the
front bumper. Therefore, the
temperature reading can be affected
by heat reflection from the road
surface, engine heat, and the
exhaust from surrounding traffic.
This can cause an incorrect
te mperature 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
inco rrectly displayed, you can adjust
it up 5°F in U.S. models ( 3°C in
Canadian models) warmer or cooler. NOTE:
The temperature must be
stabilized before doing this
procedure.
To adjust the outside temperature
indicator, make sure the outside
temperature indicator is shown in
thedisplay,thenpressandholdthe
RESET button for 10 seconds (the
TRIP A or B is also reset). The
following sequence will appear for 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 RESET button. You
should see the new outside
te mperature displayed.
In certain weather conditions,
temperature readings near freezing
(32°F, 0°C) could mean that ice is
forming on the road surface.
This
shows the temperature of the
engine’s coolant. During normal
operation, the pointer should rise to
about the middle of the gauge. In
severe driving conditions, the pointer
may rise to the upper zone. If it
reaches the red (hot) mark, pull
safely to the side of the road. For
instructions and precautions on
checking the engine’s cooling
system, see page . 286

The heater uses engine coolant to
warm the air. If the engine is cold, it
will be several minutes before you
feel warm air coming from the
system. Air
conditioning places an extra load
on the engine. Watch the engine
coolant temperature gauge (see page ). If it moves near the red zone,
turn of f the A/C until the gauge
reading returns to normal.
Turn on the A/C by pressing the
button. The display shows A/C
ON on when a f an speed is
selected.
Make sure the temperature is set
to maximum cool.
Select .
If the outside air is humid, select
recirculation mode. If the outside
air is dry, select f resh air mode.
Set the f an to the desired speed. you can
cool it down more rapidly by partially
opening the windows, turning on the
A/C, and setting the fan to
maximum speed in f resh air mode.
To cool the interior with MAX A/C:
Select .
When you select , the system
automatically switches to the fresh
air mode.
Set the f an to the desired speed.
Adjust the warmth of the air with
the temperature control dial. Set the f an to the desired speed.
Select MAX A/C mode.
The system automatically turns on
the A/C, selects , and
switches to recirculation mode.
Make sure the temperature is set
to maximum cool.

If you drive primarily in urban areas that have high
concentrations of soot in the air from industry and from diesel-
powered vehicles, replace every 15,000 miles (24,000 km).
Driving in mountainous areas at very low vehicle speeds or
trailer towing results in higher transmission and transfer
temperatures or frequently fully loaded. This requires
transmission and transfer fluid changes more frequently
than recommended by the Maintenance Minder.
If you regulary drive your vehicle under these conditions, have
the transmission and transfer fluid changed every 30,000 miles
(48,000 km).
If you drive regularly in very high tempera tures (over 110°F,
43°C), in very low temperatures (under-20°F, -29°C), or towing a
trailer, replace every 60,000 mile (U.S.)/100,000 km (Canada)
Driving in mountainous areas at very low vehicle speeds or
trailer towing results in higher level of me chanical (shear) stress
to fluid or frequently fully loaded. This requires differential fluid
changes more frequently than recommended by the
Maintenance Minder. If you regularly drive your vehicle under
these conditions, have the differential fluid changed at
7,500 miles (12,000 km), then every 15,000 miles (24,000 km).

If the message ‘‚SERVICE DUE NOW ’’ does not appear more than 12 months
after the display is reset, change the engine oil every year.
See information on maintenance and emissions warranty on page .
Independent of the maintenance messages in the information display,
replace the brake fluid every 3 years.
Inspect idle speed every 160,000 miles (256,000 km).
Adjust the valves during services A, B, 1, 2, or 3 only if they are noisy.

If the temperatu re gauge stays at
the red mark, turn off the engine.
Look for any obvious coolant leaks,
such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you find a leak, it
must be repaired before you
continue driving (see
on page ).
Put the radiator cap back on
tightl y. Run the engine, and watch
the temperatu re 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.
If you do not f ind an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark.
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 pointer
reaches the middle of the tempera-
ture gauge, or lower, bef ore check-
ing 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.Start the engine, and set the
temperature to maximum heat
(climate control to AUTO at
‘‘ ’’). 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.

Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and
radiator cool down before
removing the radiator cap.
