2009 Acura TSX Temperature sensor

This shows the outside Fahrenheit
temperature in U.S. models, and
Centigrade temperature in Canadian
models.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.
You can adjust the outside
temperature display (see page ).
The temperature sensor is in the
f ront bumper. The temperature
reading can be affected 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 vehicle speed is under
19 mph (30 km/h). When you start
your trip, the sensor is not f ully
acclimatized, theref ore it may take
several minutes until the proper
temperature is displayed.
This shows your current f uel
mileage.
When you turn of f the engine, INST.
MPG or INST. L/100 km is also
reset.

In the HI setting, the heater turns off
when the seat gets warm, and turns
back on after the seat’s temperature
drops.
In the LO setting, the heater runs
continuously. It does not cycle with
temperature changes.
Follow these precautions whenever
you use the seat heaters:If the engine is lef t idling f or an
extended period, do not use the
seat heaters even on the LO
setting. It can weaken the battery,
causing hard starting.
Use the HI setting only to heat the
seats quickly, because it draws
large amounts of current f rom the
battery.
Both f ront seats are equipped with
seat heaters. Because of the sensors
f or the side airbag cutof f system,
there is no heater in the passenger’s
seat-back. The ignition switch must
be in the ON (II) position to use the
heaters. Push the front of the switch, HI, to
rapidly heat up the seat. Af ter the
seat reaches a comfortable
temperature, select LO by pushing
the back of the switch. This will keep
the seat warm.

When the indicator in the dual
button is on, the driver’s side and
passenger’s side temperature can be
controlled independently (see page).
When you set the temperature to its
lower limit ( ) or its upper limit
( ), the system runs at f ull
cooling or heating only. It does not
regulate the interior temperature.
When you adjust a f an control, the
f an is taken out of AUTO mode.
In AUTO mode, the vehicle’s interior
temperature is independently
regulated f or the driver and f ront
passenger according to each
adjusted temperature. The system
also regulates each temperature
basedontheinformationof thesun
light sensor and the sun position
which is updated automatically by
the navigation’s global positioning system (GPS). For example, if the
driver’s side of the vehicle is getting
too much sun, the system will adjust
to a lower temperature.
You can set the temperatures for the
driver’s side and the passenger’s side
separately when this button is
pressed (indicator is on). When the
indicator in the DUAL button is of f ,
the temperatures for both sides are
synchronized to the driver’s side set
temperature. When def rost mode is
selected, dual mode operation is
canceled.
If you press the OFF button, the
climate control system shuts of f
completely.
Keep the system completely of f
f or short periods only.
To keep stale air and mustiness
f rom collecting, you should have
the f an running at all times.

Your vehicle is equipped with a tire
pressure monitoring system (TPMS)
that turns on every time you start the
engine and monitors the pressure in
your tires while driving.If you think you can saf ely drive a
short distance to a service station,
proceed slowly to the station, then
inflate the tire to the recommended
pressure.
Driving on a signif icantly under-
inf lated tire causes the tire to
overheat and can lead to tire failure.
Under-inf lation also reduces f uel
efficiency and tire tread life, and may
af f ect the vehicle’s handling and
stopping ability.
Becausetirepressurevariesby
temperature and other conditions,
the low tire pressure/TPMS
indicator may come on unexpectedly.
If the tire is flat, or if the tire
pressure is too low to continue
driving, replace the tire with the
compact spare tire (see page ).
Each tire has its own pressure
sensor. If the air pressure of a tire
becomes signif icantly low, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure/TPMS indicator in the
instrument panel to come on. If this
happens, you will see which tire is
losing pressure on the multi-
inf ormation display along with a
‘‘CHECK TIRE PRESSURE’’
message. It is possible that the pressures
shown on the multi-inf ormation
display and the pressures you
manually measure are slightly
dif f erent.
If the dif f erence is signif icant or you
cannot make the low tire pressure/
TPMS indicator and message on the
multi-inf ormation display go out af ter
inf lating the tires to the specif ied
values, have your dealer check the
system as soon as possible.
When the low tire pressure/TPMS
indicator is on, one or more of your
tires is signif icantly underinf lated.
Youshouldstopandcheckyourtires
as soon as possible, and inflate them
to the proper pressure as indicated
on the vehicle’s tire inf ormation
placard.458Low Tire Pressure/
