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
