Touching the door lock sensor while wearing gloves may delay or prevent
lock operation. Remove the gloves and touch the lock sensor again.
If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. In that case, follow the
following correction procedures to wash the vehicle:
• Place the electronic key in a location 2 m (6 ft.) or more away from the
vehicle. (Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the smart entry
& start system. (P. 149)
If the electronic key is inside the vehicle and a door handle becomes wet
during a car wash, a message may be shown on the multi-information dis-
play and a buzzer will sound outside the vehicle. To turn off the alarm, lock
all the doors.
The lock sensor may not work properly if it comes into contact with ice,
snow, mud, etc. Clean the lock sensor and attempt to operate it again, or use
the lock sensor on the lower part of the door handle.
Fingernails may scrape against the door during operation of the door han-
dle. Be careful not to injure fingernails or damage the surface of the door.
Note for the unlocking function (vehicles with entry function)
A sudden approach to the effective range or door handle may prevent the
doors from being unlocked. In this case, return the door handle to the origi-
nal position and check that the doors unlock before pulling the door handle
again.
Gripping the door handle when wearing a glove may not unlock the door.
If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. In that case, follow the
following correction procedures to wash the vehicle:
• Place the electronic key in a location 2 m (6 ft.) or more away from the
vehicle. (Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the smart entry
& start system. (P. 149)
If there is another electronic key in the detection area, it may take slightly
longer to unlock the doors after the door handle is gripped.
Fingernails may scrape against the door during operation of the door han-
dle. Be careful not to injure fingernails or damage the surface of the door.

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. (P. 867)
As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms
indicate that the electronic key battery may be depleted. Replace the battery
when necessary. (P. 777)

CAUTION
Trunk easy closer (vehicles with power trunk lid)
Power trunk lid (if equipped)
Observe the following precautions when operating the power trunk lid.
Failure to do so may cause serious injury.
Check the safety of the surrounding area to make sure there are no obsta-
cles 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 suddenly shut 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 lid 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 shut, causing an accident.
• When the trunk lid contacts an obstacle
• When the 12-volt battery voltage suddenly drops, such as when the

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 when-
ever the parking brake shoes and/or drum are replaced. Have any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional
perform the bedding down operation.
Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availabil-
ity of the correct fuel. (P. 929)
For efficient use
Shift the shift lever to D when driving.
In the N position, the gasoline engine operates but electricity cannot be gen-
erated. The hybrid battery (traction battery) will discharge, 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 electric motor (traction motor)
without 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
discharge the hybrid battery (traction battery). The vehicle cannot run if the
hybrid battery (traction battery) is discharged.
