Use this position f or
your normal driving. The transmis-
sion automatically selects a suitable
gear f or your speed and acceleration.
You may notice the transmission
shif ting up at higher speeds when
the engine is cold. This helps the
engine warm up f aster.
This position is similar
to D , except only the first three
gears are selected. Use D when
towing a trailer in hilly terrain, or to
provide engine braking when going
down a steep hill. D can also keep
the transmission f rom cycling
between third and f ourth gears in
stop-and-go driving.
ForfasteraccelerationwheninD or
D , you can get the transmission to
automatically downshif t by pushing
the accelerator pedal to the floor.
The transmission will shif t down one
or two gears, depending on your
speed. This position locks
thetransmissioninsecondgear.It
does not downshif t to f irst gear
when you come to a stop. Second
gives you more power when climbing,
and increased engine braking when
going down steep hills. Use second
gear when starting out on a slippery
surf ace or in deep snow. It will help
reduce wheelspin.
To shif t f rom Second to
First, push down on the shif t lever.
With the lever in this position, the
transmission locks in First gear. By
upshif ting and downshif ting through
1, 2, D and D , you can operate this
transmission much like a manual
transmission without a clutch pedal. If you exceed the maximum speed
f or the gear you are in, the engine
speed will enter into the tachometer’s
red zone. If this occurs, you may f eel
the engine cut in and out. This is
caused by a limiter in the engine’s
computer controls. The engine will
run normally when you reduce the
RPM below the red zone.

µMake sure the moonroof and the
windows are closed.
Place any packages, valuables, etc.,
in the trunk or take them with you. Turn of f the lights.
Lockthedoorswiththekeyorthe
remote transmitter. Check the
indicator on the driver’s door to
verify that the security system is
set.
Never park over dry leaves, tall
grass, or other f lammable
materials. The three way catalytic
converter gets very hot, and could
cause these materials to catch on
fire.
Always use the parking brake when
you park your car. The indicator on
the instrument panel shows that the
parking brake is not f ully released; it
does not indicate that the parking
brakeisfirmlyset.Makesurethe
parking brake is set f irmly or your
car may roll if it is parked on an
incline.
Make sure the parking brake is f ully
released bef ore driving away.
Driving with the parking brake
partially set can overheat or damage
the rear brakes.
Set the parking brake bef ore you put
the transmission in Park. This keeps
the vehicle from moving and putting
pressure on the parking mechanism
in the transmission making it
easier to move the shif t lever out of
Park when you want to drive away. If the vehicle is f acing downhill, turn
the f ront wheels toward the curb. If the vehicle is f acing uphill, turn
the f ront wheels away f rom the curb.

Your Acura has been designed
primarily to carry passengers and
their cargo. You can use it to tow a
trailer if you caref ully observe the
load limits, use the proper equipment,
and f ollow the guidelines in this
section.The weight that
the tongue of a f ully-loaded trailer
puts on the hitch should be
approximately 10 percent of the
trailer weight. Too little tongue
load can make the trailer unstable
and cause it to sway. Too much
tongue load reduces f ront-tire
traction and steering control.
The total
weight of the trailer and
everything loaded in it must not
exceed 2,000 lbs (900 kg). Towing
a load that is too heavy can
seriously af f ect your car’s
handling and perf ormance. It can
also damage the engine and
drivetrain.

To achieve a proper tongue load,
start by loading 60 percent of the
load toward the front of the trailer
and 40 percent toward the rear, then
re-adjust the load as needed.The total weight of the vehicle, all
occupants, all cargo, and the
tongue load must not exceed:
The total weight of the vehicle, all
occupants, all cargo, and the
tongue load must not exceed: The best way to conf irm that vehicle
and trailer weights are within limits
is to have them checked at a public
scale.
Using a suitable scale or a special
tongue load gauge, check the tongue
load the f irst time you set up a
towing combination (a f ully-loaded
vehicle and trailer), then recheck the
tongue load whenever the conditions
change.

improperly loading your car and
trailer can cause a crash in
which you can be seriously
injured or killed.
Check the loading of your car
and trailer carefully before
starting to drive.

Towing can require a variety of
equipment, depending on the size of
your trailer, how it will be used, and
how much load you are towing.
Discuss your needs with your trailer
sales or rental agency, and f ollow the
guidelines in the rest of this section.
Also make sure that all equipment is
properly installed and that it meets
f ederal, state, province, and local
regulations.Acura recommends that any trailer
having a total weight of 1,000 lbs
(450 kg) or more be equipped with
its own electric or surge-type brakes.
Always use saf ety chains. Make sure
they are secured to both the trailer
and hitch, and that they cross under
the tongue so they 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. Any hitch used on your car must be
properly bolted to the underbody.
If you choose electric brakes, be
sure they are electronically actuated.
Do not attempt to tap into your car’s
hydraulic system. No matter how
successf ul it may seem, any attempt
to attach trailer brakes to your car’s
hydraulic system will lower braking
ef f ectiveness and create a potential
hazard.

Your car has a trailer lighting
connector located in the trunk by the
lef t taillight. To use the connector,
undo the f astener on the lef t side of
the trunk lining. Ref er to the
drawing in this page f or the wiring
color code and purpose of each pin.
If you use a converter, you can get
the connector and pins that mate
with the connector in your car f rom
your Acura dealer.
Since lighting and wiring vary in
trailer type and brand, you should
also have a qualif ied mechanic install
a suitable connector between the
vehicleandthetrailer.

When driving down hills, reduce
your speed and shif t down to 2nd
gear. Do not ‘‘ride’’ the brakes, and
remember it will take longer to slow
downandstopwhentowingatrailer.
When climbing hills, closely watch
your temperature gauge. If it nears
the red (Hot) mark, turn the air
conditioning of f , reduce speed and, if
necessary, pull to the side of the
road to let the engine cool.
If the automatic transmission shif ts
f requently between 3rd and 4th
gears while going up a hill, shif t to
D.
The added weight, length, and
height of a trailer will af f ect your car’s
handling and perf ormance, so
driving with a trailer requires some
special driving skills and techniques.

discussed below.
Drive slower than normal in all
driving situations, and obey posted
speed limits f or vehicles with trailers.
Use the D position when towing a
trailer on level roads. D is the
proper shif t lever position to use
when towing a trailer in hilly terrain.
(See ‘‘
’’ in the next
column f or additional gear
inf ormation.) Make turns more slowly and wider
than normal. The trailer tracks a
smaller arc than your car, and it can
hit or run over something the vehicle
misses. Allow more time and
distance f or braking. Do not brake or
turn suddenly as this could cause the
trailer to jackknif e or turn over.

use the f oot brake or parking brake.
Do not try to hold the vehicle in

Follow all normal precautions when
parking, including putting the
transmission in Park and f irmly
setting the parking brake. Also, place
wheel chocks at each of the trailer’s
tires.
Always drive slowly and have
someone guide you when backing up.
Grip the of the steering
wheel; then turn the wheel to the lef t

trailer to the right. Crosswinds and air turbulence
caused by passing trucks can disrupt
your steering and cause trailer
swaying. When being passed by a
large vehicle, keep a constant speed
and steer straight ahead. Do not try
to make quick steering or braking
corrections.
