NX300h_U_OM78007UExhaust gas precautions Harmful substance to the human body are contained in exhaust gases if
inhaled. WA R N I N G
Exhaust gases contain harmful carbon monoxi de (CO), which is colorless and odorless.
Observe the following precautions.
Failure to do so may cause exhaust gases enter the vehicle and may lead to an accident
caused by light-headedness, or may lead to death or a serious health hazard. ■
Important points while driving ●
Keep the back door closed. ●
If you smell exhaust gases in the vehicle even when the back door is closed, open the
windows and have the vehicle inspected at your Lexus dealer as soon as possible. ■
When parking ●
If the vehicle is in a poorly ventilated area or a closed area, such as a garage, stop the
hybrid system. ●
Do not leave the vehicle with the hybrid system on for a long time.
If such a situation cannot be avoided, park the vehicle in an open space and ensure
that exhaust fumes do not enter the vehicle interior. ●
Do not leave the hybrid system operating in an area with snow build-up, or where it is
snowing. If snowbanks build up around the vehicle while the hybrid system is operat-
ing, exhaust gases may collect and enter the vehicle. ■
Exhaust pipe
The exhaust system needs to be checked periodically. If there is a hole or crack caused
by corrosion, damage to a joint or abnormal exhaust noise, be sure to have the vehicle
inspected and repaired by your Lexus dealer.

* : AWD models onlyYour vehicle is a hybrid vehicle. It ha s characteristics different from conven-
tional vehicles. Be sure you are closely familiar with the characteristics of your
vehicle, and operate it with care.
The hybrid system combines the use of a gasoline engine and an electric
motor (traction motor) according to dr iving conditions, improving fuel effi-
ciency and reducing exhaust emissions.

78 1-2. Hybrid system
NX300h_U_OM78007U ◆ When stopped/during start off
The gasoline engine stops* when the vehi cle is stopped. During start off, the
electric motor (traction mo tor) drives the vehicle. At slow speeds or when
traveling down a gentle slope, the engi ne is stopped* and the electric motor
(traction motor) is used.
When the shift lever is in N, the hybrid battery (traction battery) is not being
charged. When the vehicle is stopped, always put the shift lever to P.
Also, even in heavy traffic conditions, drive the vehicle in D or S.
* : When the hybrid battery (traction battery) requires charging or the engine is warm-
ing up, etc., the gasoline engine will not automatically stop. (  P. 7 9 )
◆ During normal driving
The gasoline engine is predominantly used. The electric motor (traction
motor) charges the hybrid battery (traction battery) as necessary.
◆ When accelerating sharply
When the accelerator pedal is depressed heavily, the power of the hybrid bat-
tery (traction battery) is added to that of the gasoline engine via the electric
motor (traction motor).
◆ When braking (regenerative braking)
The wheels operate the electric motor (traction motor) as a power generator,
and the hybrid battery (tr action battery) is charged.
When driving with the gasoline engine stopped, a sound, which changes in
accordance with the driving speed, will be played in order to warn people
nearby of the vehicle’s approach. The sound will stop when the vehicle speed
exceeds approximately 15 mph (25 km/h).Vehicle proximity notification system

Regenerative braking
In the following situations, kinetic energy is converted to electric energy and decelera-
tion force can be obtained in conjunction with the recharging of the hybrid battery (trac-
tion battery). ●
The accelerator pedal is released while driving with the shift lever in D or S.●
The brake pedal is depressed while driv ing with the shift lever in D or S.■

Conditions in which the ga soline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop automati-
cally in the following conditions: ●
During gasoline engine warm-up ●
During hybrid battery (t raction battery) charging●
When the temperature of the hybrid battery (traction battery) is high or low ●
When the heater is switched on ■
Charging the hybrid battery (traction battery)
As the gasoline engine charges the hybrid battery (traction battery), the battery does not
need to be charged from an outside source. However, if the vehicle is left parked for a
long time the hybrid battery (traction battery) will slowly discharge. For this reason, be
sure to drive the vehicle at least once ever y few months for at least 30 minutes or 10
miles (16 km). If the hybrid battery (tractio n battery) becomes fully discharged and you
are unable to start the hybrid system, contact your Lexus dealer. ■
Charging the 12-volt battery
 P. 5 9 7 ■
After the 12-volt battery has discharged or when the terminal has been removed and
installed during exchange, etc.
The gasoline engine may not stop even if the ve hicle is being driven by the hybrid battery
(traction battery). If this continues for a few days, contact your Lexus dealer.The EV indicator comes on when the vehicle is
driven using only the electric motor (traction
motor) or the gasoline engine is stopped.

tery (traction battery), behind the rear seats, when the hybrid system is started or
stopped. ●
Sounds from the hybrid system may be heard when the back door is open. ●
Sounds may be heard from the transmission wh en the gasoline engine starts or stops,
when driving at low speeds, or during idling. ●
Engine sounds may be heard when accelerating sharply. ●
Sounds may be heard due to regenerative braking when the brake pedal is depressed
or as the accelerator pedal is released. ●
Vibration may be felt when the gasoline engine starts or stops.●
Cooling fan sounds may be heard from the air intake vents under the rear seats. ■
