Diagnostic Info
When an indicator comes on or a
message is displayed on the Multi-
Information Display (MID),
AcuraLink can provide information
about the cause of the indicator or
message and the recommended
action to address it. This helps you
handle the problem as it occurs,
preventing or limiting costly repairs.
The AcuraLink system cannot
determine some mechanical
problems (such as squeaks or
rattles) that are not triggered by the
diagnostic indicator monitors.
For more information on the
instrument panel indicators, see page
64.
When an indicator comes on or a
message is displayed on the MID,
AcuraLink immediately notifies you
with the message,‘‘An indicator is
on. AcuraLink can help you decide
what to do. ’’If you do not want the
information right away, select the
Check Later option. If you want the
information now, select the Check
Now option. (If the navigation screen
is not active, you must select OK
from the navigation disclaimer
screen before you can check the
information.) Depending on the severity of the
problem, the message will let you
know if you should see your dealer
immediately or if you can wait until a
later date.

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.

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.

Shift Lever Position IndicatorsThese indicators on the instrument
panel show which position the shift
lever is in. In the Sequential
SportShift Mode, the‘‘M’’ indicator
next to the ‘‘D ’’indicator comes on,
and the illuminated number under
the charging system indicator shows
you the gear you have selected. The
‘‘D ’’indicator comes on for a few
seconds when you turn the ignition
switch to the ON (II) position. If it
flashes while driving (in any shift
position), it indicates a possible
problem in the transmission.
If the malfunction indicator lamp
comes on along with the ‘‘D ’’
indicator, there is a problem with the
automatic transmission control
system. Avoid rapid acceleration, and
have the transmission checked by
your dealer as soon as possible.
When the ‘‘D ’’indicator warns of a
possible problem with the
transmission, you will see a ‘‘CHECK
TRANSMISSION ’’message on the
multi-information display (see page
82). Shifting
To shift from Park to any position,
press firmly on the brake pedal, and
press the release button on the front
of the shift lever, then move the
lever. You cannot shift out of Park
when the ignition switch is in the
LOCK (0) or ACCESSORY (I)
position.

slippery surface.
If you start out in second gear, the
transmission will be fixed in that
gear.
The transmission will not
automatically downshift to first gear
even when the vehicle speed is
under 10 mph (16 km/h). You need
to shift down to first gear manually.

To see the inflation pressures of all
four tires, press the SEL/RESET
button. The display changes as
shown above.
Each tire pressure is shown in PSI
(U.S. models) or in kPa (Canadian
models).
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.
U.S. model
Canadian model
This shows that front left tire
is losing pressure.

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.
