Towing

If the vehicle needs to be towed, call a professional tow-

ing service. Never tow the vehicle behind another vehi-

cle with just a rope or chain. It is very dangerous.

There are three widely used methods of towing a vehicle.

Flat-bed Equipment — The operator loads the vehicle on

the back of a truck. This is the only recommended way

of towing the NSX & NSX-T.

Wheel Lift Equipment — The tow truck driver uses two

pivoting arms which go under the tires (front or rear)

and lift them off the ground. The other two wheels

remain on the ground. This towing method is not rec-

ommended. Because of the NSX & NSX-T's low ground

clearance, the body can be damaged going over large

bumps or up inclines.

Sling-type Equipment — The tow truck uses metal

chains with hooks on the ends. These hooks go around

parts of the frame or suspension and the cables lift that

end of the vehicle off the ground. Damage to the vehi-

cle's suspension and body is almost certain if this

method of towing is attempted.

If the NSX & NSX-T cannot be towed by flat-bed, it

should be towed with the rear wheels off the ground. If,

due to damage, the vehicle must be towed with the rear

wheels on the ground, do the following:

Manual Transmission

• Release the parking brake

• Shift the transmission to Neutral

Automatic Transmission

• Release the parking brake

• Start the engine

• Shift to position, then to position

• Turn off the engine

NOTICE:

• Improper towing preparation will damage the trans-

mission. Follow the above procedure exactly. The car

must be towed on a flat bed if the engine will not

start or the transmission will not shift.

• It is best to tow the vehicle no farther than 50 miles

(80 km), and keep the speed below 35 mph (55 km/h).

• Trying to lift or tow the vehicle by the bumpers will

cause serious damage. The bumpers are not

designed to support the vehicle's weight.ProCarManuals.com

Service Precautions

Handling of Special Nuts and Bolts

Handling of Tires

• The tires on NSX & NSX-T should not be rotated. The

front wheels are 16" in, diameter and the rear wheels

are 17" in, so they cannot be rotated front-to-rear.

The original-equipment tires on NSX & NSX-T have a

unidirectional tread pattern, so they cannot be rotat-

ed side-to-side.

• The folding spare tire cannot be repaired or removed

from the rim.

Engine Steam-cleaning

(NSX-T only)

When steam-cleaning the engine compartment, keep the

roof holder switch dry. If the roof holder switch gets wet

accidentally, dry it thoroughly with compressed air.
Because many sections on this vehicle are constructed

with aluminum alloys, use only the special "Dacro" type

nuts and bolts recommended by Acura.

NOTE:

• Dacro finish can be identified by gray plating.

• Some Dacro finish bolts have a green coating on the

thread section of the bolt for easier application. This

type of bolt is called a "Torquer" bolt.

• Use of other types of nuts and bolts may cause elec-

trolysis and corrosion, which in turn could cause the

bolt to loosen.

Gray plating: "Dacro" type

Gray plating + Green coating on the threads:

"Torquer" type

1. When replacing nuts and bolts, use only the same

type.

2. Tighten the nuts and bolts with a torque wrench to

the specifications provided in this manual.

3. Clean all thread ridges with a non-wire-type bristle

brush. Foreign matter in the threads may cause the

bolt to loosen.

4. Sections on this vehicle requiring the use of Dacro nuts

and bolts will be indicated by a in this manual.ProCarManuals.com
