To operate the system properly
Make sure to carry the electronic key wh en operating the system. Do not get the
electronic key too close to the vehicle wh en operating the system from the outside

If the smart access system with push-button start does not operate properly ●
Locking and unlocking the doors: Use the mechanical key. ( P. 7 9 3 )●

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 engine
stops. ( P. 766)●
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 nec-
essary. ( P. 7 0 1 )
• The smart access system with push-but ton start or the wireless remote con-
trol 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

Before driving CAUTION●
In the following situations, the power b ack door may detect an abnormality and
automatic operation may be stopped. In this case, the back door has to be oper-
ated manually. Take extra care when on an incline, as the back door may open or
close abruptly.
• When the back door contacts an obstacle
• When the battery voltage suddenly drops, such as when the “ENGINE
START STOP” switch is turned to IGNITION ON mode or the engine is
started during 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
to be caught and injured. When installing an accessory part to the back door,
using a genuine Lexus part is recommended.■
Jam protection function
Observe the following precautions.
Failure to do so may cause death or serious injury. ●
Be careful while the jam protection function is operating. Being hit by the back
door may result in an injury.●
Although the back door stops closing wh en the jam protection function detects
an object, take extra care as you may still be injured if part of your body is already
caught.●
If anything obstructs the power back door while it is closing, the jam protection
function will cause the back door to automatically operate in the opposite direc-
tion. However, be careful not to jam body parts in the doorframe, as an injury may
result.●
Never use any part of your body to intent ionally activate the jam protection func-
tion.
●
The jam protection function may not work if something gets caught just before
the back door fully closes. Be careful not to catch fingers or anything else.
