Oil CheckWait a few minutes after turning the
engine off before you check the oil.1. Remove the dipstick (orange loop).
2. Wipe off the dipstick with a clean cloth or paper towel.
3. Insert the dipstick all the way back into its hole.
4. Remove the dipstick again, andcheck the level. It should be
between the upper and lower
marks.
If it is near or below the lower mark,
see Adding Engine Oil on page393.Engine Coolant Check
Look at the coolant level in the
radiator reserve tank. Make sure it is
between the MAX and MIN lines. If
it is below the MIN line, see
Adding
Engine Coolant on page396for
information on adding the proper
coolant.
Refer to Owner's Maintenance
Checks on page389for information
about checking other items on your
vehicle.

Fuel Economy Factors
The following factors can lower your
vehicle's fuel economy:●Aggressive driving (hard
acceleration and braking)●Excessive idling, accelerating and
braking in stop-and-go traffic●Cold engine operation (engines
are more efficient when warmed
up)●Driving with a heavy load or the air
conditioner running●Improperly inflated tiresImproving Fuel EconomyVehicle MaintenanceA properly maintained vehicle
maximizes fuel economy. Poor
maintenance can significantly reduce
fuel economy. Always maintain your
vehicle according to the maintenance
messages displayed on the information
display (seeOwner's Maintenance
Checks on page389).For example:
●Use the recommended viscosity
motor oil, displaying the API
Certification Seal (see page393).●Maintain proper tire inflation －
An under-inflated tire increases
‘‘ rolling resistance, ’’which reduces
fuel economy.●Avoid carrying excess weight in
your vehicle －It puts a heavier
load on the engine, increasing fuel
consumption.●Keep your vehicle clean －In
particular, a build-up of snow or mud
on your vehicle's underside adds
weight and rolling resistance.
Frequent cleaning helps your fuel
economy.Drive Efficiently●Drive moderately －Rapid
acceleration, abrupt cornering, and
hard braking increase fuel
consumption.
●Observe the speed limit －
Aerodynamic drag has a big effect
on fuel mileage at speeds above 45
mph (75 km/h). Reduce your
speed and you reduce the drag.
Trailers, car top carriers, roof
racks and bike racks are also big
contributors to increased drag.●Avoid excessive idling －Idling
results in 0 miles per gallon.
Fuel Economy32808/06/06 16:58:07 09 ACURA MDX MMC North America Owner's M 50 31STX620 enu

●Minimize the use of the air
conditioning system－The A/C
puts an extra load on the engine
which makes it use more fuel. Use
the fresh-air ventilation when
possible.●Plan and combine trips －
Combine several short trips into
one. A warmed-up engine is more
fuel efficient than a cold one.
Calculating Fuel EconomyMeasuring TechniquesDirect calculation is the
recommended source of information
about your actual fuel economy.
Using frequency of fill-ups or taking
fuel gauge readings are NOT
accurate measures of fuel economy.
Fuel economy may improve over the
first several thousand miles.
Checking Your Fuel Economy1)Fill the fuel tank until the nozzle automatically clicks off.
2)Reset trip counter to zero.
3)Record the total gallons (liters) needed to refill.
4)Follow one of the simple calculations above.

6. Check the adjustment of the insideand outside mirrors (see page
154).
7. Check the steering wheel adjustment (see page 124).
8. Make sure the doors and tailgate are securely closed and locked.
9. Fasten your seat belt. Check that your passengers have fastened
their seat belts (see page 15).
10. When you start the engine, check the gauges and indicators in the
instrument panel, and the
messages on the multi-information
display (see pages 63,72and 81). Starting the Engine
Your vehicle's starting system has an
auto control mode. When you turn
the ignition switch to the START (III)
position, this feature keeps the
engine's starter motor running until
the engine starts. Follow these
instructions to start the engine:
1. Apply the parking brake.
2. In cold weather, turn off all
electrical accessories to reduce the
drain on the battery.
3. Make sure the shift lever is in Park. Press on the brake pedal.
4. Without touching the accelerator pedal, turn the ignition switch to
the START (III) position, then
release the ignition switch. You do
not need to hold the ignition
switch in the START (III) position
to start the engine. Depending on
the outside temperature, the
starter motor runs for about 6 to 9
seconds until the engine starts. If you hold the ignition switch in
the START (III) position for more
than 7 seconds, the starter motor,
depending on the outside
temperature, runs for about 10 to
25 seconds until the engine starts.
If the engine does not start, wait at
least 10 seconds before trying
again.
The immobilizer system protects your
vehicle from theft. If an improperly-
coded key (or other device) is used, the
engine's fuel system is disabled. For
more information, see page
128.

5. If the engine does not start within15 seconds, or starts but stalls
right away, repeat step 4 with the
accelerator pedal pressed halfway
down. If the engine starts, release
pressure on the accelerator pedal
so the engine does not race.
6. If the engine fails to start, press the accelerator pedal all the way
down, and hold it there while
starting to clear flooding. If the
engine still does not start, return to
step 5.The engine is harder to start in cold
weather. Also, the thinner air found at
altitudes above 8,000 feet (2,400
meters) adds to this problem. Check Starting System Message
If there is a problem with the starting
system, you will see a
‘‘CHECK
STARTING SYSTEM ’’message on
the multi-information display when
the ignition switch is turned to the
ON (II) position. You will also see
this message when the auto control
mode of the starting system has a
problem. If this message is on, the ignition
switch has to be held in the START
(III) position manually until the
engine starts. The ignition switch can
be held in that position up to 15
seconds.
Even though you may be able to start
the engine manually without the auto
control mode of the starting system,
have your dealer inspect your
vehicle.

3. Put a cloth on the edge of the shiftlock release slot cover. Use a small
flat-tipped screwdriver or metal
fingernail file to carefully pry up
the edge of the cover and remove
it from the slot.
4. Insert a key into the shift lockrelease slot.
5. Push down on the key while you press the release button on the
front of the shift lever and move
the shift lever out of Park to
neutral. 6. Remove the key from the shift lock
release slot, then reinstall the
cover. Make sure the notch on the
cover is on the driver's side. Press
the brake pedal, and restart the
engine.
If you need to use the shift lock
release, it means your vehicle is
developing a problem. Have the
vehicle checked by a dealer.

If the SH-AWD indicator blinks while
driving, it indicates the differential
temperature is too high. You will also
see an‘‘SH-AWD DIFF TEMP.
HIGH ’’message on the multi-
information display. If this happens,
pull to the side of the road when it is
safe, shift to Park, and let the engine
idle until the indicator goes out. If
the indicator does not go out, take
your vehicle to a dealer to have it
checked.
If the SH-AWD indicator on the
instrument panel stays on, and the
‘‘ CHECK SH-AWD SYSTEM ’’
message also appears on the multi-
information display, there is problem
with the SH-AWD system. Your vehicle still has normal front-
wheel drive with vehicle stability
assist (VSA), but does not have the
advantages of SH-AWD. Have your
vehicle checked by a dealer as soon
as possible.

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.
Each tire has its own pressure
sensor. If the air pressure of a tire
becomes significantly 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-
information display along with a
‘‘CHECK TIRE PRESSURE ’’
message.
Low Tire Pressure/
TPMS Indicator
When the low tire pressure/TPMS
indicator is on, one or more of your
tires is significantly underinflated.
You should stop and check your tires
as soon as possible, and inflate them
to the proper pressure as indicated
on the vehicle's tire information
placard.
It is possible that the pressures
shown on the multi-information
display and the pressures you
manually measure are slightly
different.
If the difference is significant or you
cannot make the low tire pressure/
TPMS indicator and message on the
multi-information display go out after
inflating the tires to the specified
values, have your dealer check the
system as soon as possible. If you think you can safely drive a
short distance to a service station,
proceed slowly to the station, then
inflate the tire to the recommended
pressure.
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 page425).
Driving on a significantly under-
inflated tire causes the tire to
overheat and can lead to tire failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle's handling and
stopping ability.
Because tire pressure varies by
temperature and other conditions,
the low tire pressure/TPMS
indicator may come on unexpectedly.

Braking System
Your vehicle is equipped with disc
brakes at all four wheels. A power
assist helps reduce the effort needed
on the brake pedal. The emergency
brake assist system increases the
stopping force when you depress the
brake pedal hard in an emergency
situation. The anti-lock brake system
(ABS) helps you retain steering
control when braking very hard.
Resting your foot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their effectiveness
and reduces brake pad life. In
addition, fuel economy can be
reduced. It also keeps your brake
lights on all the time, confusing
drivers behind you. Constant application of the brakes
when going down a long hill builds
up heat and reduces their
effectiveness. Use the engine to
assist the brakes by taking your foot
off the accelerator and downshifting
to a lower gear.
Check the brakes after driving
through deep water. Apply the
brakes moderately to see if they feel
normal. If not, apply them gently and
frequently until they do. Be extra
cautious in your driving.
