2003 Acura MDX Owner's Manua

µµAlways drive
slower than you would in dry
weather. It takes your vehicle longer
to react, even in conditions that may
seem just barely damp. Apply
smooth, even pressure to all the
controls. Abrupt steering wheel
movements or sudden, hard appli-
cation of the brakes can cause loss of
control in wet weather. Be extra
cautious f or the f irst f ew miles
(kilometers) of driving while you
adjust to the change in driving
conditions. This is especially true in
snow. A person can f orget some
snow-driving techniques during the
summer months. Practice is needed
to relearn those skills.
Exercise extra caution when driving
in rain af ter a long dry spell. Af ter
months of dry weather, the f irst
rains bring oil to the surf ace of the
roadway, making it slippery.
Rain, f og, and snow conditions re-
quire a dif f erent driving technique
because of reduced traction and
visibility. Keep your vehicle well-
maintained and exercise greater
caution when you need to drive in
bad weather. The cruise control
should not be used in these condi-
tions. Being able to see
clearly in all directions and being
visible to other drivers are important
in all weather conditions. This is
more dif f icult in bad weather. To be
seen more clearly during daylight
hours, turn on your headlights.
Inspect your windshield wipers and
washers f requently. Keep the wind-
shield washer reservoir f ull of the
proper f luid. Have the windshield
wiper blades replaced if they start to
streak the windshield or leave parts
unwiped. Use the def rosters and air
conditioning to keep the windows
f rom f ogging up on the inside (see
page ). 140

µCheck your tires
f requently f or wear and proper
pressure. Both are important in
preventing ‘‘hydroplaning’’ (loss of
traction on a wet surface). In the
winter, mount snow tires on all f our
wheels f or the best handling.
Watch road conditions caref ully,
they can change f rom moment to
moment. Wet leaves can be as slip-
pery as ice. ‘‘Clear’’ roads can have
patches of ice. Driving conditions
can be very hazardous when the
outside temperature is near f reezing.
The road surf ace can become
covered with areas of water puddles
mixed with areas of ice, so your
traction can change without warning.
Be caref ul when downshif ting. If
traction is low, you can lock up the
drive wheels f or a moment and cause
askid. Be very cautious when passing, or
beingpassedbyothervehicles.The
spray f rom large vehicles reduces
your visibility, and the wind buf f eting
can cause you to lose control.

Your MDX has been designed to tow
a trailer, as well as f or carrying
passengers and their cargo.
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 thesectiononpage if you
plan to tow off paved surfaces.
The
maximum weight you can tow
depends on several f actors. See
page f or limits f or your towing
situation. Towing a load that is too
heavy can seriously af f ect your
vehicle’s handling and
perf ormance. The weight that
the tongue of a f ully loaded trailer
puts on the hitch should be 5 to 10
percent of total trailer weight f or
boat trailers, and 8 to 15 percent of
total trailer weight for all other
trailers. See page f or limits f or
your towing situation.

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.

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.The GCWR must be reduced 2
percent f or every 1,000 f eet (305
meters) of elevation. The maximum allowable weight of
the f ully loaded vehicle and trailer is
9700 lbs (4410 kg) with the proper
hitch and f luid coolers (See pagef or inf ormation about f luid
coolers.)
The maximum allowable weight of
the vehicle, all occupants, all cargo
and the tongue load is 5730 lbs (2600
kg).
The maximum allowable weights on
the vehicle axles are 2890 lbs (1310
kg) on the f ront axle, and 2945 lbs
(1335 kg) on the rear axle. 277

Thebestwaytoconfirmthatall
loads are within limits is to check
them at a public scale.
To help ensure a saf e drive to a scale,
or if you cannot get to a public scale
to check the weights of your rig, we
recommended that you estimate
your total trailer weight and tongue
load as described below.
To estimate your total trailer weight,
add the weight of the trailer (as
quoted by the trailer manuf acturer)
together with everything in or on the
trailer. Then ref er to the tables on
page to conf irm that you do not
exceed the limit f or your conditions.To estimate tongue load:
Park the vehicle on level ground.
Measure f rom the ground to the
bottom of the trailer hitch. Write
this number down.
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 result f rom Step 4
f rom the result in Step 2 and ref er
to the chart (Fig. 1). If thedifferenceis:
1½ = 150 lbs (68 kg)
2¼ = 250 lbs (114 kg)3 = 350 lbs (159 kg)
3¾ = 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 total trailer weight
and tongue load do not exceed the
limits f or your towing situation (see
page ), caref ully drive your
trailer to a public scale. Be sure your
vehicle and trailer are f ully loaded,
with all occupants and cargo you
plan to take on the road.
