SPORT HYBRID Super Handling All-Wheel-Drive TM

(SPORT HYBRID SH-AWD ®)
The system controls and transfers varying amounts of motor and/or engine torque
to each wheel in accordance with the driving conditions.
SPORT HYBRID SH-AWD ® helps to enhance driving stability, and lets you handle
situations like slippery surf aces better than when drivi ng with standard two wheel
drive. However, the system does not help to enhance braking. Be cautious about the
following:• It is still your responsibility to drive sa fely when you steer, accelerate, and apply
brakes.
• Leave a sufficient margin when braking on slippery surfaces.1SPORT HYBRID Super Handling All-Wheel-Drive TM
(SPORT
HYBRID SH-AWD ®)
Do not drive through deep water.
The SPORT HYBRID SH-AWD ® system may not
function properly if tire type and size are mixed.
Make sure to use the same size and type of tire, and
the air pressures as specified.

uuWhen DrivinguTire Pressure Monitoring System (TPMS)
Driving
Tire Pressure Monitoring System (TPMS)Monitors the tire pressure while you are
driving. If your vehicle’s tire pressure becomes
significantly low, the low tire pressure/TPMS
indicator comes on and a message appears on
the driver information interface.
1Tire Pressure Monitoring System (TPMS)
Conditions such as low ambient temperature and
altitude change directly affect tire pressure and can
trigger the low tire pressure/TPMS indicator to come on. 2 If the Low Tire Pressure/TPMS Indicator
Comes On or Blinks P. 455
Tire pressure checked and inflated in: • Warm weather can beco me under-inflated in
colder weather.
• Cold weather can become over-inflated in warmer
weather.
The low tire pressure/TPMS indicator will not come
on as a result of over inflation.

uuWhen DrivinguTire Pressure Monitoring System (TPMS)
Driving
To select the tire pressure monitor, set the
power mode to ON, and roll the right selector
wheel until you see the tire pressure screen.
The pressure for each tire is displayed in PSI
(U.S.) or kPa (Canada).
Tire Pressures Low is displayed when a tire
has significantly low pressure. The specific tire
is displayed on the screen.
Tire Pressure Too Low For High Speed
Driving is displayed when driving at an
extremely high speed and one or more tires
are underinflated.
uDecelerate and drive your vehicle until
the message disappears.
■Tire Pressure Monitor1Tire Pressure Monitor The pressure displayed on the driver information
interface can be slightly different from the actual
pressure as measured by a gauge. If there is a significant di fference between the two values, or if
the low tire pressure/TPMS indicator and the message
on the driver information in terface do not go off after
you have inflated the tire to the specified pressure,
have the system checked by an authorized Acura NSX
dealer.

driver information interface if there is a problem with
the TPMS. Please have the system checked by an
authorized Acura NSX dealer.

Driving
Tire Pressure Monitoring System (TPMS) - Required
Federal Explanation
Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the vehicle placard
or tire inflation pressure label.
(If your vehicle has tires of a diff erent size than the size indicated
on the vehicle placard or tire infl ation pressure label, you should
determine the proper tire inflat ion pressure for those tires.)
As an added safety feature, your vehicle has been equipped with
a tire pressure monitoring system (TPMS) that illuminates a low
tire pressure telltale
when one or more of your tire s is significantly under-inflated.
Accordingly, when the low tire pr essure telltale illuminates, you
should stop and check your tires as soon as possible, and inflate
them to the proper pressure.
Driving on a significantly under-in flated tire causes the tire to
overheat and can lead to tire fail ure. Under-inflation also reduces
fuel efficiency and tire tread li fe, and may affect the vehicle’s
handling and stopping ability.

uuWhen DrivinguTire Pressure Monitoring System (TPMS) - Required Federal Explanation
Driving
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver ’s responsibility to maintain
correct tire pressure, even if un der-inflation has not reached the
level to trigger illumination of th e TPMS low tire pressure telltale.
Your vehicle has also been equi pped with a TPMS malfunction
indicator to indicate when the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire
pressure telltale. When the syst em detects a malfunction, the
telltale will flash fo r approximately one minute and then remain
continuously illumina ted. This sequence will continue upon
subsequent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may
not be able to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including
the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow the TPMS to
continue to function properly.

uuWhen DrivinguHigh Voltage Battery
Driving
High Voltage Battery
The High Voltage battery gradually discharges when the vehicle is not in use. As a
result, if your vehicle is parked for an ex tended period of time, the battery level may
get low. Keeping the High Vo ltage battery’s charge level low can shorten its life.
To maintain the High Voltage battery, driv e your vehicle for more than 30 minutes
to recharge it at least once every three months. Also, try to park in shaded areas
instead of direct sunlight. 2 Storage P. 428

Brake System
Use the parking brake to keep the vehicl
e stationary when parked. When the
parking brake is applied, you can manu ally or automatically release it.
■ To apply
The electric parking brake can be applied any
time the vehicle has battery, no matter which
power mode the vehicle is in.
Pull the electric parking brake switch up gently
and securely.
uThe parking brake indicator comes on.
■ To release
The power mode must be in the ON position
to release the electric parking brake. 1. Depress the brake pedal.
2. Press the electric parking brake switch.
uThe parking brake indicator goes off.
Manually releasing the parking brake using
the switch helps your vehicle start slowly and
smoothly when facing downhill on steep hills.
■Parking Brake1Brake System
When you depress the brak e pedal, you may hear a
whirring sound from the engine compartment. This is
because the brake system is in operation, and it is
normal.
1Parking Brake
You may hear the electric parking brake system
motor operating from the re ar wheel area when you
apply or release the parking brake.
You cannot apply or release the parking brake if the
12-volt battery goes dead.
2 Jump Starting P. 448
If you pull up and hold the electric parking brake
switch while driving, the brakes on all four
wheels are applied by the electric servo brake
system until the vehicle comes to a stop. The
electric parking brake then applies, and the
switch should be released .
