2015 LEXUS NX300h charging

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.

Electronic key battery depletion ●
The standard battery life is 1 to 2 years. (The card key battery life is about a year and a
half.) ●
If the battery becomes low, an alarm will sound in the cabin when the hybrid system
stops. ●
As the electronic key always receives ra dio waves, the battery will become depleted
even if the electronic key is not used. The following symptoms indicate that the elec-
tronic key battery may be depleted. Re place the battery when necessary. (  P. 5 3 2 )
• The smart access system with push-button start or the wireless remote control does
not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on. ●
To avoid serious deterioration, do not leave the electronic key within 3 ft. (1 m) of the
following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Induction cookers
• Table lamps ■

Confirmation of the registered key number
The number of keys already registered to the vehicle can be confirmed. Ask your Lexus
dealer for details. ■
If a wrong key is used
The key cylinder rotates freely to isolate inside mechanism.

Driving
NX300h_U_OM78007U ●
Reversing with a trailer attached is di fficult and requires practice. Grip the
bottom of the steering wheel and move your hand to the left to move the
trailer to the left. Move your hand to the right to move the trailer to right. (This
is generally opposite to reversing without a trailer attached.) Avoid sharp or
prolonged turning. Have someone guid e you when reversing to reduce the
risk of an accident. ●
As stopping distance is increased when towing a trailer, vehicle-to vehicle dis-
tance should be increased. For each 10 mph (16 km/h) of speed, allow at least
one vehicle and trailer length. ●
Avoid sudden braking as you may skid, re sulting in the traile r jackknifing and a
loss of vehicle control. This is especially true on wet or slippery surfaces. ●
Avoid jerky starts or sudden acceleration. ●
Avoid jerky steering and sharp turns, and slow down before making turn. ●
Note that when making a turn, the traile r wheels will be closer than the vehicle
wheels to the inside of the turn. Comp ensate by making a wider than normal
turning radius. ●
Slow down before making a turn, in cross winds, on wet or slippery surfaces,
etc.
Increasing vehicle speed can destabilize the trailer. ●
Take care when passing other vehicles. Passing requires considerable dis-
tance. After passing a vehicle, do not forget the length of your trailer, and be
sure you have plenty of room before changing lanes. ●
To maintain engine braking efficiency and charging system performance
when using engine braking, do no t put the transmission in D. (  P. 2 0 8 )●
Instability happens more frequently when descending steep or long downhill
grades. Before descending, slow down and downshift. Do not make sudden
downshifts while descending steep or long downhill grades. ●
Avoid holding the brake pedal down too long or applying the brakes too fre-
quently. This could cause the brakes to overheat and result in reduced braking
efficiency. ●
Due to the added load of the trailer, yo ur vehicle’s engine may overheat on hot
days (at temperatures over 85  F [30  C]) when driving up a long or steep
grade. If the engine coolant temperat ure gauge indicates overheating, imme-
diately turn off the air cond itioning (if in use), pull your vehicle off the road and
stop in a safe spot. (  P. 600)

When driving on slippery road surfaces
Be careful of downshifting and sudden accele ration, as this could result in the vehicle
skidding to the side or spinning.
NOTICE ■
Hybrid battery (traction battery) charge
If the shift lever is in N, the hybrid battery (traction battery) w ill not be charging, even
when the engine is running. Therefore, if the ve hicle is left with the shift lever in N for a
long period of time, the hybrid battery (tr action battery) will discharge, and this may
result in the vehicle not being able to start.
