Service Information Summary
A summary of information you need when you pull up to the fuel pump.

This indicator normally comes on f or
a f ew seconds when you turn the
ignition to ON (II).
This indicator normally comes on f or
a f ew seconds when you turn the
ignition to ON (II).
If it comes on while driving, it
indicates that one or more of your
vehicle’s tires are extremely low on
pressure.
If this happens, pull to the side of the
road when it is saf e, check which tire
has lost the pressure on the Tire
Pressure Monitor, and determine the
cause. If it is because of a f lat tire,
replace the flat tire with the compact
spare (see page ), and have the
f lat tire repaired as soon as possible.
If two or more tires are underinf lated,
call a prof essional towing service
(see page ). Ref er to page
f or more inf ormation. The appropriate tire indicator will
come on along with the Low Tire
Pressure Indicator if a tire is
extremely under inf lated or has
suddenly lost pressure. See Low Tire
Pressure Indicator f or what to do if
this indicator comes on.
If this indicator comes on and stays
on at any other time, or it does not
come on when you turn the ignition
switch to ON (II), there is a problem
with the TPMS. With this indicator
on, the low tire pressure indicator
and the tire pressure monitor will not
come on when a tire loses pressure.
Take the vehicle to your dealer to
have the system checked.

The maximum load f or your vehicle
is 1,158 lbs (525 kg). This f igure
includes the total weight of all
occupants, cargo, accessories, and
the tongue weight if you are towing a
trailer.
To determine the correct cargo and
luggage load limit:
Locate the statement, ‘‘the
combined weight of occupants and
cargo should never exceed 1,158
lbs (525 kg)’’ on your vehicle’s
placard (on the driver’s doorjamb).
Determine the combined weight
of the driver and passengers that
will be riding in your vehicle.
(Seven is the seating capacity of
your vehicle.) Subtract the combined weight of
the driver and passengers f rom
1,158 lbs (525 kg).
The resulting f igure equals the
available amount of cargo and
luggage load capacity.
For example, if there will be f ive 150
lbs (70 kg) occupants in your vehicle,
the amount of available cargo and
luggage load capacity is 408 lbs (175
kg).
5 150 lbs (70 kg) = 750 lbs (350
kg)
1,158 lbs (525 kg) 750 lbs (350 kg)
= 408 lbs (175 kg) Determine the combined weight
of accessories, luggage, and cargo
beingloadedinthevehicle.The
weight may not saf ely exceed the
available cargo and luggage load
capacity calculated in step 4 [408
lbs(175kg)inthisexample]. If your vehicle will be towing a
trailer, the load f rom your trailer
will be transf erred to your vehicle.
Consult this manual to determine
how this reduces the available
cargo and luggage load capacity of
your vehicle.

To saf ely tow a trailer, you should
observe the load limits, use the
proper equipment, and f ollow the
guidelines in this section.
Be sure to read the Of f -Highway
Driving Guidelines section on page
if you plan to tow of f paved
surf aces. To help ensure a saf e drive to a scale,
or if you cannot get to a public scale,
we recommend that you estimate
your total trailer weight and tongue
load as described next.
The maximum
allowable weight of the vehicle, all
occupants, all cargo and the tongue
load is 5,787 lbs (2,630 kg).
Thebestwaytoconfirmthatall
loads are within limits is to check
them at a public scale. The GCWR must be reduced 2
percent f or every 1,000 f eet (305
meters) of elevation. See page f or limits f or your
towing situation.
Add the weight of your trailer (as
quoted by the manuf acturer) with
everything in or on the trailer. Check
the tables on page that you do
not exceed the limit f or your
conditions.
The maximum
allowable weight on the vehicle axles
are 2,882 lbs (1,307 kg) on the f ront
axle, and 2,992 lbs (1,360 kg) on the
rear axle.

Exceeding any load limit or
improperly loading your vehicle
and trailer can cause a crash in
which you can be seriously hurt
or killed.
Check the loading of your
vehicle and trailer carefully
beforestartingtodrive.

The weight that the tongue of a f ully
loaded trailer puts on the hitch
shouldbe5to10percentof thetotal
trailer weight f or boat trailers, and 8
to 15 percent of total trailer weight
f or all other trailers. See page f or
limits f or your towing situation.Too much tongue load reduces f ront-
tire traction and steering control.
Too little tongue load can make the
trailer unstable and cause it to sway.
Park the vehicle on level ground.
Measure and record the distance
from the ground to the bottom of
the trailer hitch.
Connect the f ully loaded trailer to
the hitch.
Measure again f rom the ground to
the same spot on the bottom of the
hitch.
Subtract the second measurement
f rom the f irst measurement. Ref er
to Fig. 1. If thedifferenceis:
1 ½’’ = 150 lbs (68 kg)
2 ¼’’ = 250 lbs (114 kg)3’’ = 350 lbs (159 kg)
3 ¾’’ = 450 lbs (204 kg) 4’’ = over 450 lbs (204 kg)
If thedifferenceismorethan4’’
you have too much tongue load
at the rear. Move or remove
cargo f rom the trailer and the
vehicle, and measure again.
If the estimated trailer weight and
tongue load do not exceed the limits,
drive your trailer to a public scale
f ully loaded with all occupants and
cargo you plan to take on the road.

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
