3-2. Opening, closing and locking the doors and trunk
CAUTION
■Trunk easy closer (vehicles with power trunk opener and closer)
■Power trunk opener and closer (if equipped)
Observe the following precautions when operating the power trunk opener and
closer.
Failure to do so may cause serious injury.
●Check the safety of the surrounding area to make sure there are no obstacles or
anything that could cause any of your belongings to get caught.
●If anyone is in the vicinity, make sure they are safe and let them know that the
trunk is about to open or close.
●If the trunk closer switch is pressed while the trunk lid is opening during automatic
operation, the trunk lid stops opening. Take extra care when on an incline, as the
trunk lid may open or close suddenly.
●On an incline, the trunk lid may fall after it opens automatically. Make sure the
trunk lid is fully open and secure before using the trunk.
●In the following situations, the power trunk opener and closer may detect an
abnormality and automatic operation may be stopped. In this case, the trunk lid
has to be operated manually. Take extra care in this situation, as the stopped trunk
lid may suddenly fall, causing an accident.
• When the trunk lid contacts an obstacle
• When the 12-volt battery voltage suddenly drops, such as when the “START STOP ENGINE” <“POWER”> switch is turned to IGNITION ON
mode or the engine is started during automatic operation
●Do not attach any accessories other than genuine Lexus parts to the trunk lid. The
power trunk opener and closer may not operate, causing itself to malfunction, or
the trunk lid may fall closed again after it is opened.
In the event that the trunk lid is left slightly
open, the trunk easy closer will automatically
close it to the fully closed position. It takes
several seconds before the trunk easy closer
begins to operate. Be careful not to catch fin-
gers or anything else in the trunk lid, as this
may cause bone fractures or other serious
injuries.

4-1. Before driving
■Breaking in your new Lexus
To extend the life of the vehicle, observing the following precautions is recom-
mended:
●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 low gears.
• Do not drive at a constant speed for extended periods.
■Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of brake system
needs bedding-down of the brake shoes periodically or whenever the parking brake
shoes and/or drum are replaced. Have your Lexus dealer perform the bedding
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. 847)
■For efficient use (hybrid vehicles)
●Shift the shift lever to D when driving.
In the N position, the gasoline engine operates but electricity cannot be generated.
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 decelera-
tion will make more effective use of the electric motor (traction motor) without hav-
ing 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.

■Switching to EV drive mode when the gasoline engine is cold
If the hybrid system is started while the gasoline engine is cold, the gasoline engine
will start automatically in order to warm up. In this case, you will become unable to
switch to EV drive mode.
After the hybrid system has started and the “READY” indicator has illuminated,
press the EV drive mode switch before the gasoline engine starts to switch to EV
drive mode.
■Automatic cancelation of EV drive mode
When driving in EV drive mode, the gasoline engine may automatically restart in the
following situations. When EV drive mode is canceled, a buzzer will sound and the
EV indicator will flash 3 times and go off.
●The hybrid battery (traction battery) becomes low.
The remaining battery level indicated in the “Energy Monitor” screen or the multi-
information display is low. ( →P. 112)
●Vehicle speed becomes more than about 25 mph (40 km/h).
●The accelerator pedal is depressed firmly.
When it is possible to inform the driver of automatic cancelation in advance, a prior
notice screen will appear on the multi-information display.
■Possible driving distance when driving in EV drive mode
EV drive mode’s possible driving distance ranges from a few hundred meters to
approximately 1.3 mile (2 km). Driving is possible at speeds of less than approxi-
mately 25 mph (40 km/h). However, depending on vehicle conditions, there are sit-
uations when EV drive mode cannot be used.
(The distance that is possible depends on the hybrid battery [traction battery] level
and driving conditions.)
■Fuel economy
Your Lexus is designed to achieve the best possible fuel economy during normal
driving (using the gasoline engine and electric motor [traction motor]). Driving in EV
drive mode more than necessary may lower fuel economy.
