SRS airbag precautions ●
If breathing becomes difficult after the SRS airbags have deployed, open a door or
window to allow fresh air in, or leave the vehicl e if it is safe to do so. Wash off any resi-
due as soon as possible to prevent skin irritation. ●
If the areas where the SRS airbags are stored, such as the steering wheel pad and
front and rear pillar garnishes, are damaged or cracked, have them replaced by your
Lexus dealer. ●
Do not place anything, such as a cushion, on the front passenger’s seat. Doing so will
disperse the passenger’s weight, which prevents the sensor from detecting the pas-
senger’s weight properly. As a result, th e SRS front airbags for the front passenger
may not deploy in the event of a collision. ■
Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications without
consulting your Lexus dealer. The SRS airb ags may malfunction or deploy (inflate)
accidentally, causing de ath or serious injury.●
Installation, removal, disassembl y and repair of the SRS airbags●
Repairs, modifications, removal or replac ement of the steering wheel, instrument
panel, dashboard, seats or seat upholstery, fr ont, side and rear pillars or roof side rails●
Repairs or modifications of the front fend er, front bumper, or side of the occupant
compartment ●
Installation of a grille guar d (bull bars, kangaroo bar, etc.), snow plows, winches or
roof luggage carrier ●
Modifications to the vehicle’s suspension system ●
Installation of electronic devices such as mobile two-way radios and CD players●
Modifications to your vehicle for a person with a physical disability

If the SRS airbags deploy (inflate) ●
Bruising and slight abrasions may result fr om contact with a deploying (inflating) SRS
airbag. ●
A loud noise and white powder will be emitted. ●
Parts of the airbag module (steering wheel hub, airbag cover and inflator) as well as the
front seats, parts of th e front and rear pillars, and roof side rails, may be hot for several
minutes. The airbag itself may also be hot. ●
The windshield may crack. ●
For Safety Connect subscribers, if the SRS airbags deploy or in the event of a severe
rear-end collision, the system is designed to send an emergency call to the response
center, notifying them of the vehicle’s location (without needing to push the “SOS” but-
ton) and an agent will attempt to speak wi th the occupants to ascertain the level of
emergency and assistance required. If the oc cupants are unable to communicate, the
agent automatically treats the call as an em ergency and helps to dispatch the necessary
emergency services. (  P. 477)■
SRS airbag deployment conditions (SRS front airbags) ●
The SRS front airbags will deploy in the event of an impact that exceeds the set threshold
level (the level of force corresponding to an approximately 12-18 mph [20-30 km/h]
frontal collision with a fixed wall that does not move or deform).
However, this threshold velocity will be considerably higher in the following situations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole, which can move
or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in which the
front of the vehicle “underrides”, or goes under, the bed of a truck●
Depending on the type of collision, it is possib le that only the seat belt pretensioners will
activate. ●
The SRS front airbags for the front passenger will not activate if there is no passenger
sitting in the front passenger seat. However, the SRS front airbags for the front passen-
ger may deploy if luggage is put in the seat, even if the se at is unoccupied. (  P. 5 3 )●
The SRS seat cushion airbag on the front passenger seat will not operate if the occu-
pant is not wearing a seat belt. ■
SRS airbag deployment conditions (S RS side and curtain shield airbags)●
The SRS side and curtain shie ld airbags will deploy in th e event of an impact that
exceeds the set threshol d level (the level of force corresponding to the impact force
produced by an approximately 3300 lb. [1 500 kg] vehicle colliding with the vehicle
cabin from a direction perpendicular to the vehicle orientation at an approximate
speed of 12 -18 mph [20 -30 km/h]). ●
The SRS curtain shield airbags will deploy in the event of vehicle rollover. ●
The SRS side and curtain shield airbags may al so deploy in the event of a severe frontal
collision.

The portion of the front pillars, rear pillars or
roof side rail garnishes (padding) containing
the curtain shield airbag s inside is scratched,
cracked, or otherwise damaged.

Driving
NX300h_U_OM78007U ◆ Delays
Repeated acceleration and deceleration, as well as long waits at traffic lights,
will lead to bad fuel economy. Check traffic reports before leaving and avoid
delays as much as possible. When drivin g in a traffic jam, gently release the
brake pedal to allow the vehicle to move forward slightly while avoiding over-
use of the accelerator pedal. Doing so can help control excessive gasoline
consumption.
◆ Highway driving
Control and maintain the vehicle at a co nstant speed. Before stopping at a toll
booth or similar, allow plenty of time to release the accelerator and gently
apply the brakes. A greater amount of electrical energy can be regenerated
when slowing down.
◆ Air conditioning
Use the air conditioning only when necessary. Doing so can help reduce
excessive gasoline consumption.
In summer: When the ambient temperature is high, use the recirculated air
mode. Doing so will help to reduce th e burden on the air conditioning system
and reduce fuel consumption as well.
In winter: Because the gasoline engine will not automatically cut out until it
and the interior of the vehicle are warm, it will consume fuel. Also, fuel con-
sumption can be improved by avoiding overuse of the heater.
◆ Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. Improper tire infla-
tion pressure can cause poor fuel economy.
Also, as snow tires can cause large amou nts of friction, their use on dry roads
can lead to poor fuel economy. Use ti res that are appropriate for the season.
◆ Luggage
Carrying heavy luggage will lead to poor fuel economy. Avoid carrying
unnecessary luggage. Installing a large roof rack will also cause poor fuel
economy.
◆ Warming up before driving
Since the gasoline engine starts up and cuts out automatically when cold,
warming up the engine is unnecessary. Moreover, frequently driving short dis-
tances will cause the engine to repeated ly warm up, which can lead to excess
fuel consumption.

When searching for a track ●
A USB memory or iPod must be connected to enable track searching and playback.
(  P. 3 4 5 ) ●
When a USB memory or iPod is connected, recognition data is created so tracks can
be searched using voice commands. ●
Recognition data is updated un der the following conditions:
• When the USB memory or iPod data has changed.
• When the voice recognition language is changed. (  P. 3 4 8 )●
While the recognition data is being created or being updated, a track search cannot be
performed using a voice command. ■

Due to natural language speech recognitio n technology, this system enables rec-
ognition of a command when spoken naturally. However, the system cannot rec-
ognize every variation of each command.
In some situations, it is possible to omit the command for the procedure and
directly state the desired operation.
