kPa), turn off the compressor.
1Injecting Sealant and Air
NOTICE
Do not operate the temporary tire repair kit compressor
for more than 15 minutes. The compressor can overheat
and become permanently damagedM
Until the sealant injection is complete, the pressure
shown on the pressure gauge will appear higher than
actual. After the sealant injection is complete the
pressure will drop and then begi n to rise again as the tire
is inflated with air. This is normal. To accurately measure
the air pressure using the gauge, turn the air compressor
off only after the sealan t injection is complete.
If the required air pressure is not reached within 15
minutes, the tire may be too severely damaged for
the kit to provide the necessa ry seal and your vehicle
will need to be towed.
See an authorized Acura NSX dealer for a replacement
sealant bottle and proper disposal of an empty bottle.

Emergency Power System Off
The ENGINE START/STOP button may be used to turn the power system off due to
an emergency situation even while driving. If you must turn the power system off,
do either of the following operations:
• Press and hold the ENGINE START/STOP button for about two seconds.
• Firmly press the ENGINE START/STOP button three times.
The steering wheel will not lock. However, because turning off the engine disables
the power assist the engine provides to the steering and braking systems, it will
require significantly more physical effort an d time to steer and slow the vehicle. Use
both feet on the brake pedal to slow down the vehicle and stop immediately in a
safe place.
The gear position automatically changes to
(P after the vehicle comes to a complete
stop. Then, the power mode changes to VEHICLE OFF.

Turn off the power to electric devices, such as audio and lights. Turn off the power
system, then open the hood.1.Remove the maintenance cover.
2 Checking the 12-Volt Battery P. 421
2.Slide the terminal cover on your vehicle’s
12-volt battery positive + terminal as
shown.
3. Connect the first jump er cable to your
vehicle’s 12-volt battery + terminal.
4. Connect the other end of the first jumper
cable to the booster battery + terminal.
u If you use a booster battery, only use a
12-volt booster battery.
u When using an automotive battery
charger, select a charging voltage lower
than 15-volts. Check the charger manual
for the proper setting.
5. Connect the second jumper cable to the
booster battery - terminal.
■Jump Starting Procedure1If the 12-Volt Battery Is Dead
Securely attach the jumper cable clips so that they do
not come off when the engine vibrates. Also be
careful not to tangle the ju mper cables or allow the
cable ends to touch each other while attaching or
detaching the jumper cables.
12-volt battery performa nce degrades in cold
conditions and may prevent the engine from starting.
3WARNING
A 12-volt battery can explode if you do not
follow the correct procedure, seriously
injuring anyone nearby.
Keep all sparks, open flames, and smoking
materials away from the 12-volt battery.Terminal Cover
