2003 Acura MDX engine

This meter shows the number of
miles (U.S.) or kilometers (Canada)
driven since you last reset it.
There are two trip meters: Trip A
and Trip B. Switch between these
displays by pressing the Select
button repeatedly. Each trip meter
works independently, so you can
keep track of two dif f erent distances.
When you turn the ignition switch
ON (II), what you last selected isdisplayed.
To reset a trip meter, display it, and
then press and hold the Reset button
until the number resets to ‘‘0.0’’.
Both trip meters will reset if the
vehicle’s battery goes dead or is
disconnected.
This shows the temperature of the
engine’s coolant. During normal
operation, the pointer should rise
from the bottom blue mark to about
the middle of the gauge. In severe
driving conditions, such as very hot
weather or a long period of uphill
driving, the pointer may rise to the
upper white mark. If it reaches the
red (Hot) mark, pull saf ely to the
side of the road. Turn to page f or
instructions and precautions on
checking the engine’s cooling
system.
This shows how much f uel you have.
It is most accurate when the vehicle
is on level ground. It may show
slightly more or less than the actual
amount when you are driving on
curvy or hilly roads.
The needle returns to the bottom
after you turn off the ignition. The
gauge shows the f uel level reading
immediately af ter you turn the
ignition switch back ON (II).

The Immobilizer System protects
your vehicle f rom thef t. A properly-
coded master or valet key must be
used in the ignition switch f or the
engine to start. If an improperly-
coded key (or other device) is used,
the engine’s f uel system is disabled.
When you turn the ignition switch to
ON (II), the Immobilizer System
indicator should come on f or a f ew
seconds, then go out. If the indicator
starts to blink, it means the system
does not recognize the coding of the
key. Turn the ignition switch to
LOCK (0), remove the key, reinsert
it, and turn the switch to ON (II)
again.The system may not recognize your
key’s coding if another immobilizer
key or other metal object is near the
ignition switch when you insert the
key. To make sure the system
recognizes the key code:
Do not keep other immobilizer
keys on the same key ring.
Use a plastic or leather key f ob,
not metal.
Keep other keys away f rom your
vehicle’s key and the ignition
switch while trying to start the
engine. If the system repeatedly does not
recognize the coding of your key,
contact your Acura dealer.
The Immobilizer System indicator
will also blink several times when
you turn the ignition switch f rom ON
(II) to ACCESSORY (I) or LOCK (0).
Do not attempt to alter this system
or add other devices to it. Electrical
problems could result that may make
your vehicle undriveable.
If you have lost your key and you
cannot start the engine, contact your
Acura dealer.

Both f ront seats are equipped with
seat heaters. The ignition switch
must be ON (II) to use them. Push
the front of the switch, HI, to rapidly
heat up the seat. After the seat
reaches a comf ortable temperature,
select LO by pushing the back of the
switch. This will keep the seat warm.Follow these precautions whenever
you use the seat heaters:
Use the HI setting only to heat the
seats quickly. Select the LO
setting when the seats f eel warm.
The HI setting draws large
amounts of current f rom the
battery.
Do not use the seat heaters, even
on the LO setting, if the engine is
lef t idling f or an extended period.
They can weaken the battery,
causing hard starting.
The HI or LO indicator lights and
remains lit until you turn it of f by
pushing the opposite side of the
switch lightly. The indicator will turn
off.
In HI, the heater turns of f when the
seat gets warm, and turns back on
after the seat’s temperature drops. It
continues to cycle as long as you
leave it set on HI. The HI indicator
remains lit as a reminder that you
have the heater on.
In LO, the heater runs continuously.
It does not cycle with temperature
changes.
Because of the sensors f or the side
airbag system, there is no heater in
the passenger’s seat-back.
