CAUTION: (if roof maintenance is required)
Be careful not ot bend the edge of the roof opening.
The roof is made of aluminum alloy. Take care not to dent or scratch the roof. If there is a minor dent or scratch on the roof, repair
the roof with putty (refer to the body repair manual).
When replacing the component parts of the roof, place the roof on an appropriate pad to prevent damage.
NOTE:
Have an assistant help remove the roof.
When the roof is stored on the engine cover, lock the roof cover securely.
When installing the roof, secure it by turning both roof side lock handles. Make sure they are locked securely.

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
