differential Acura MDX 2009 Owner's Manual

Message Indicator
This indicator comes on when there
is a system message on the multi-
information display. Press the INFO
button on the steering wheel (see
page73)to see the message (see
page81).
Most of the time, this indicator
comes on along with other indicators
in the instrument panel such as the
seat belt reminder indicator, SRS
indicator, VSA system indicator, etc.
Super Handling-All
Wheel Drive (SH-AWD)
Indicator
This indicator normally comes on for
a few seconds when you turn the
ignition switch to the ON (II)
position. If this indicator comes on at
any other time, there is a problem in
the SH-AWD system. You will also
see a ‘‘CHECK SH-AWD SYSTEM ’’
message on the multi-information
display (see page82).Take your
vehicle to a dealer to have it checked.
For more information, see page348. If the indicator blinks while driving,
it indicates the differential
temperature is too high.
You will also see a
‘‘SH-AWD DIFF
TEMP. HIGH ’’message on the multi-
information display (see page82).
Pull to the side of the road when it is
safe, shift to Park, and let the engine
idle until the indicator goes out.
Continuing to drive with the SH-AWD
indicator blinking may cause serious
damage to the system.

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.

Maintenance Sub Items
1
●Rotate tires
2●Replace air cleaner element
If you dirve in dusty conditions, replace every 15,000
miles (24,000 km).●Replace dust and pollen filterIf you dirve 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).●Inspect drive belt
3●Replace transmission and transfer fluid
4●Replace spark plugs●Replace timing belt and inspect water pump If you drive regularly in very high temperatures (over
110°F, 43°C), in very low temperatures (under －20°F, －
29°C), or towing a trailer, replace every 60,000 miles (U.
S.)/100,000 km (Canada).●Inspect valve clearance
5●Replace engine coolant
6●Replace rear differential fluid Driving in mountainous areas at very low vehicle
speeds or trailer towing results in higher level of
mechanical (shear) stress to fluid. 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).
