• When the 12-volt battery voltage suddenly drops, such as when the
“POWER” switch is turned to ON mode or the hybrid system is started dur-
ing automatic operation●
If a bicycle carrier or similar heavy object is attached to the back door, the power
back door may not operate, causing itself to malfunction, or the back door may
suddenly shut again after being opened, causing someone’s hands, head or neck

Install the 12-volt battery cover using the clips. (  P. 6 6 7 )
Using the lever to open the fuel filler door may not allow for an adequate reduction
in fuel tank pressure before refueling. To prevent fuel from spilling out, turn the cap
slowly when removing it.
During refueling, fuel may spill out from the filler opening due to air being dis-
charged from inside the fuel tank. Therefore, fill the fuel tank carefully and slowly.■
Fuel types
Unleaded gasoline (Octane rating 91 [R esearch Octane Number 96] or higher)STEP 1

(Stopping the alarm deactivates the alarm system.)
■
Alarm-operated door lock ●
When the alarm is operating, the door s are locked automatically to prevent
intruders.●

1682-1. Driving procedures
■
Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of brake sys-
tem needs bedding-down of the brake shoe s periodically or whenever the parking
brake shoes and/or drum are replaced. Have your Lexus dealer perform the bed-
ding down operation.■
Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the
correct fuel. (  P. 800)■
For efficient use ●
Shift the shift lever to D when driving.
In the N position, the gasoline engine op erates but electricity cannot be gener-
ated. The hybrid battery (traction battery) will discharge, requiring unnecessary
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 electric motor (t raction motor) with-
out having to use gasoline engine power.●
Avoid repeated acceleration.
Repeated acceleration consumes hybrid battery (traction battery) power,
resulting in poor acceleration. Battery power can be restored by driving with
the accelerator pedal slightly released.●
Shift the shift lever to 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 time may dis-
charge the hybrid battery. The vehicle cannot run if the hybrid battery is dis-
charged.■
Eco-friendly driving
 P. 1 9 9
CAUTION
■
When starting the vehicle
Always keep your foot on the brake pe dal while stopped with the hybrid system
operating. This prevents the vehicle from creeping.

Auto power off function
When the shift lever is in P, if the vehicle is left in ACCESSORY or ON mode with
the hybrid system not operating for more than 20 minutes (ACCESSORY mode)
or one hour (ON mode), the “POWER” switch will automatically turn off. However,
this function cannot entirely prevent 12-v olt battery discharge. Do not leave the
vehicle with the “POWER” switch in ACCESSORY or ON mode for long periods
of time when the hybrid system is not operating.■
Operation of the “POWER” switch
When operating the “POWER” switch, one short, firm press is enough. If the switch
is pressed improperly, the hybrid system may not start or the “POWER” switch
mode may not change. It is not necessary to press and hold the switch.■
