When driving
■Breaking in your new Lexus
To extend the life of the vehicle, the following precautions are recommended to
obser
ve:
●For the first 186 miles (300 km): 
Avoid sudden stops.
●For the first 621 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in the low gears.
• Do not drive at a constant speed for extended periods.
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the
co
rrect fuel. ( P. 4 8 2 )
■For efficient use
●Put the shift lever into “D” when driving 
In the “N” position, the gasoline engine operates but electricity cannot be gen -
erated. The hybrid ba tter
y (traction battery) will be discharged requiring unnec-
essary engine power to recharge.
●Drive your vehicle smoothly 
Avoid abrupt acceleration and deceleration. Gradual acceleration and decel -
eration will make more effective use of the traction motor without having to use
g
asoline engine power.
●Avoid repeated acceleration 
Repeated acceleration consumes hybrid battery (traction battery) power,
r
esulting in poor acceleration. Battery power can be restored by driving with
the accelerator pedal slightly released.
●Put the shift lever into “P” when parking 
In the “N” position, the hybrid battery (traction battery) does not recharge. 
Leaving the shift lever in the “N” position for an extended period of the time may
di
scharge the hybrid battery. The vehicle cannot run if the hybrid battery is dis-
charged.
■When starting on an incline
The hill-start assist control may operate. ( P. 1 6 2 )

deal

er immediately.

If the “READY” light does not come on when you press the power switch with the
shi
ft lever in “P” and the brake pedal pressed, contact your Lexus dealer immedi -
ately.
■Auto power OFF function
The power switch will automatically turn OFF when lef
t in “ACC” mode for 1 hour or
more.
