the pedals or seat operation.
Keep the glove box closed while
driving. If it is open, a passenger
could injure their knees during a
crash or sudden stop.Distribute cargo evenly on the
f loor of the cargo area, placing the
heaviest items on the bottom and
as f ar f orward as possible. Tie
down items that could be thrown

Your vehicle has higher ground
clearance that allows you to travel
over bumps, obstacles, and rough
terrain. It also provides good
visibility so you can anticipate
problems earlier.
Because your vehicle rides higher
of f the ground, it has a high center
of gravity that can cause it to roll
over if you make abrupt turns. Utility
vehicles have a signif icantly higher
roll over rate than other types of
vehicles.
To prevent rollovers or loss of
control:Take corners at slower speeds
than you would with a passenger
vehicle.
Avoid sharp turns and abrupt
maneuvers whenever possible. Do not modif y your vehicle in any
way that would raise the center of
gravity.
Do not carry heavy cargo on the
roof .
Youshoulddothefollowingchecks
and adjustments bef ore you drive
your vehicle. Make sure all windows, mirrors,
and outside lights are clean and
unobstructed. Remove f rost, snow,
or ice. Make sure the doors and tailgate
are securely closed and locked. Check the steering wheel
adjustment (see page ). Check the adjustment of the
inside and outside mirrors (see
page ). Check the seat adjustment (see
page ). Check that any items you may be
carrying are stored properly or
f astened down securely.
When you start the engine, check
the gauges and indicators in the
instrument panel (see page ).
Visually check the tires. If a tire
looks low, use a gauge to check its
pressure. Fasten your seat belt. Check that
your passengers have f astened
their seat belts (see page ).

Towing generally requires a variety
of supplemental equipment. To
ensure the best quality, we
recommend that you purchase Acura
equipment whenever possible.
Discuss any additional needs with
your trailer sales or rental agency,
and make sure all equipment is
properly installed, maintained, and
also meets state regulations.
A weight distributing hitch is not
recommended f or use with your
MDX.Always use saf ety chains when you
tow a trailer. Make sure the chains
are secured to the trailer and hitch,
and that they cross under the tongue
and can catch the trailer if it
becomes unhitched. Leave enough
slack to allow the trailer to turn
corners easily, but do not let the
chains drag on the ground.
This device is recommended if your
trailer tends to sway. Your trailer
maker can tell you what kind of sway
control you need and how to install it.
To help prevent overheating, a
heavy-duty transmission f luid cooler
and a heavy-duty power steering
f luid cooler are required f or trailer
towing. These coolers are available
only f rom your Acura dealer.
Acura requires that any trailer with a
total trailer weight of 1,000 lbs (455
kg) or more have its own brakes.
There are two common types of
trailer brakes: surge and electric.
Surge brakes are common f or boat
trailers, since the brakes will get wet.
Electric brakes must be
electronically actuated. Do not
attempt to tap into your vehicle’s
hydraulic system. See your brake
manuf acturer f or more inf ormation
on installing electric brakes.
Many states and provinces require
special exterior mirrors when towing
a trailer. Even if they don’t, you
should install special mirrors if you
cannot clearly see behind you, or if
the trailer creates a blind spot.
We strongly recommend that you
have your Acura dealer install an
Acura hitch and use the required
f luid coolers. Using non-Acura
equipment may result in serious
damage to your vehicle. T owing Equipment and

Oil is a major contributor to your
engine’s perf ormance and longevity.
Always use a premium-grade 5W-20
detergent oil displaying the API
Certif ication Seal. This seal indicates
the oil is energy conserving, and that
it meets the American Petroleum
Institute’s latest requirements.Honda Motor Oil is the pref erred
5W-20 lubricant f or your vehicle. It is
highly recommended that you use
Honda Motor Oil in your vehicle f or
optimum engine protection. Make
sure the API Certif ication Seal says
‘‘For Gasoline Engines’’.
The oil viscosity or weight is
provided on the container’s label.
5W-20 oil is f ormulated f or year-
round protection of your Acura to
improve cold weather starting and
f uel economy.
Unscrew and remove the engine oil
fill cap on top of the valve cover.
Pour in the oil slowly and caref ully so
you do not spill. Clean up any spills
immediately. Spilled oil could
damage components in the engine
compartment. Install the engine oil
f ill cap and tighten it securely. Wait a
f ew minutes and recheck the oil level
(see page ). Do not f ill above the
upper mark on the dipstick; you
could damage the engine. 161 Recommended Engine Oil
