For Safe Driving
The following pages explain your vehicle’s safety features and how to use them 
properly. The safety precauti ons below are ones that we consider to be among the 
most important.
Important Safety Precautions ■ Always wear your seat belt
A seat belt is your best protection in all types of collisions. Airbags are designed to  
supplement seat belts, not replace them. So  even though your vehicle is equipped 
with airbags, make sure you and your pass enger always wear your seat belts, and 
wear them properly. ■ Your vehicle is not recommended for child passengers
The National Highway Traffic Safety Ad ministration and Transport Canada 
recommend that all children  ages 12 and under be properly restrained in a back 
seat. Since this vehi cle does not have a back seat, we strongly recommend that you 
do not carry any child who is not large enough and mature enough to ride in front. ■ Be aware of airbag hazards
While airbags can save lives, they can cause serious or fatal injuries to occupants  
who sit too close to them, or are not prop erly restrained. Infants, young children, 
and short adults are at the greatest risk.  Be sure to follow all instructions and 
warnings in this manual.

Safe Driving
■Pay appropriate attention to the task of driving safely
Engaging in cell phone conversation or other activities that keep you from paying  
close attention to the road, other vehicles, and pedestrians could lead to a crash.  
Remember, situations can change quickly, and only you can decide when it is safe to 
divert some attention away from driving. ■ Control your speed
Excessive speed is a major factor in crash  injuries and deaths. Generally, the higher 
the speed, the greater the risk, but serious  injuries can also occur at lower speeds. 
Never drive faster than is safe for current conditions, regardless of the maximum  speed posted. ■ Keep your vehicle  in safe condition
Having a tire blowout or a mechanical failure can be extremely hazardous. 
To reduce the possibility of such problems, check your tire pressures and condition  
frequently, and perform all regul arly scheduled maintenance.
■ Do not leave children  unattended in the vehicle
Children, pets and people needing assistan ce left unattended in the vehicle may be 
injured if they activate one or more of the vehicle controls. They  may also cause the 
vehicle to move, resulting in a crash in wh ich they and/or another person(s) can be 
injured or killed. Also, depending on the am bient temperature, the temperature of 
the interior may reach extreme levels,  which can result in harm or death.
Even if the climate control system is on,  never leave them in the vehicle unattended 
as the climate control system can shut off at any time.

Safety Checklist 
For the safety of you and your passenger, make a habit of checking these items each 
time before you drive. • After everyone has entered the vehicle, be  sure both doors are closed and locked. 
Locking the doors helps prevent an occupant from being ejected and an outsider  
from unexpectedly opening a door. 2 Locking/Unlocking the Doors from the Inside  P. 115
• Adjust your seat to a position suitable fo r driving. Be sure the seats are adjusted 
as far to the rear as possible while allo wing the driver to control the vehicle. 
Sitting too close to a front airbag can resu lt in serious or fatal injury in a crash.
2 Adjusting the Seats  P. 144
• Always wear your seat belt, and make sure  you wear it properly. Confirm that any 
passenger is properly belted as well. 2 Fastening a Seat Belt  P. 39
• If you choose to ignore our warnings and carry a child in this vehicle, make every  
effort to protect them by properly using a se at belt or a child seat according to the 
child’s age, height, and weight. 2 Child Safety  P. 58
1Safety Checklist 
If the Door Open  or Door And Trunk Open  
message appears on the driver information interface,  a door and/or the trunk (h atch) is not completely 
closed. Close both doors and  the trunk (hatch) tightly 
until the message disappears.

Seat Belts
About Your Seat Belts 
Seat belts are the single most effective safety device because they keep you 
connected to the vehicle so  that you can take advantage of many built-in safety 
features. They also help keep you from be ing thrown against the inside of the 
vehicle, against any passenger, or out of th e vehicle. When worn properly, seat belts 
also keep your body properly positioned in a crash so that you can take full  
advantage of the additional protec tion provided by the airbags.
In addition, seat belts help protect you in almost every type of crash, including:- frontal impacts
- side impacts
- rear impacts
- rollovers
■ Lap/shoulder seat belts
Both seating positions are equipped with  lap/shoulder seat belts with emergency 
locking retractors. In normal driving the re tractor lets you move freely while keeping 
some tension on the belt. During a collision or sudden stop the retractor locks to 
restrain your body. The passenger’s seat be lt has a lockable retractor that must be 
properly activated when using a forward-facing child seat, should you choose to  
disregard our recommendations and install one. 2 Installing a Child Seat  P. 63
1About Your Seat Belts 
Seat belts cannot complete ly protect you in every 
crash. But in most cases,  seat belts can reduce your 
risk of serious injury. 
Most states and all Canadian provinces and territories  
require you to w ear seat belts.
If you extend the seat belt t oo quickly, it will lock in 
place. If this happens, sli ghtly retract the seat belt, 
then extend it slowly.
3WARNING
Not wearing a seat belt  properly increases 
the chance of serious  injury or death in a 
crash, even though your vehicle has  
airbags. 
Be sure you and your passenger always  
wear seat belts and wear them properly.

■Proper use of seat belts
Follow these guidelines for proper use: • All occupants should sit upright, well back  in the seat, and remain in that position 
for the duration of the trip. Slouching an d leaning reduce the effectiveness of the 
belt and can increase the chance of serious injury in a crash.
• Never place the shoulder part of a lap/shoulder seat belt under your arm or  
behind your back. This could cause very serious injuries in a crash.
• Two people should never use the same seat  belt. If they do, they could be very 
seriously injured in a crash.
• Do not put any accessories on the seat be lts. Devices intended to improve comfort 
or reposition the shoulder part of a seat  belt can reduce the protective capability 
and increase the chance of  serious injury in a crash.
The seat belt system includes an indicator on 
the instrument panel to remind the driver or a  
passenger or both to fasten their seat belts. 
If you set the power mode to ON and a seat 
belt is not fastened, a beeper will sound and  
the indicator will blink. After a few seconds,  
the beeper will stop and the indicator will 
come on and remain illuminated until the seat  belt is fastened. 
The beeper will periodically sound and the  
indicator will blink while the vehicle is moving  
until the seat belt is fastened.
■Seat Belt Reminder
1About Your Seat Belts 
If your passenger moves  around and extends the seat 
belt, the lockable retractor may activate. If this  
happens, release the retractor by unfastening the 
seat belt and allow the belt to retract completely.  
Then refasten the belt.
1Seat Belt Reminder 
The indicator will also co me on if a passenger does 
not fasten their seat belt  within six seconds after the 
power mode is set to ON. 
When no one is sitting in th e passenger’s seat, or a 
child is riding there, the  indicator will not come on 
and the beeper will not sound.

Safe DrivingThe driver’s and passenger’s seats are  
equipped with automatic seat belt tensioners 
to enhance safety. 
The tensioners automatically tighten the seat  
belts during a moderate-to-severe frontal  
collision, sometimes even if the collision is not  
severe enough to inflate the front airbags or 
the driver’s knee airbag.
■Automatic Seat Belt Tensioners1Automatic Seat Belt Tensioners 
The seat belt  tensioners can  only operate once.
If a tensioner is activated, the SRS indicator will come  on. Have an authorized Ac ura NSX dealer replace the 
tensioner and thoroughly insp ect the seat belt system 
as it may not offer protecti on in a subsequent crash.
During a moderate-to-sev ere side impact, the 
tensioner on that side of  the vehicle also activates.
