■Luggage compartment (120 V AC)
The power outlet can be used for 120 V AC accessories that run on less than
100 W.
■The power outlet can be used when
12 V DC: The engine switch is in
ACCESSORY or IGNITION ON mode.
120 V AC: The engine switch is in IGNITION ON mode.
■The protection circuit may be activated to cut the power supply if any of the following
conditions apply (120 V AC):
●Use of electrical appliances exceeding 100 W is attempted.
A sound may be heard when the protection circuit is activated. This is normal and does
not indicate a malfunction.
●The total power usage by all electrical features (headlights, air conditioning, etc.) has
exceeded the total vehicle maximum for an extended period of time.
■If the protection circuit is activated and th e power supply is cut, conduct the following
procedure (120 V AC):
Park the vehicle in a safe place, and then securely apply the parking brake.
Make sure that the power consumption of th e electric appliance is within the maxi-
mum capacity of the power outlet and the appliance is not broken.
Turn the engine switch to IGNITION ON mode again.
When the cabin temperature is high, open the windows to cool the temperature down.
Once it reaches the normal temperature, turn the engine switch to IGNITION ON

■Languages
The Safety Connect resp
onse center will offer support in multiple languages. The Safety
Connect system will offer voice prompts in English and Spanish. Please indicate your lan-
guage of choice when enrolling.
■When contacting the response center
You may be unable to contact the resp onse center if the network is busy.
When the engine switch is turned to IGNITION ON mode, the red indicator
light comes on for 2 seconds then turns off. Afterward, the green indicator light
comes on, indicating that the service is active.
The following indicator light patterns indicate specific system usage conditions:
●Green indicator light on = Active service
●Green indicator light flashing = Safety Connect call in process
●Red indicator light (except at vehicle start-up) = System malfunction (contact
your Lexus dealer)
●No indicator light (off) = Safety Connect service not active
■Automatic Collis ion Notification
In case of either airbag deployment or severe rear-end collision, the system is
designed to automatically call the response center. The responding agent
receives the vehicle’s location and attempts to speak with the vehicle occu-
pants to assess the level of emergency. If the occupants are unable to commu-
nicate, the agent automatically treats the call as an emergency, contacts the
nearest emergency services provider to describe the situation, and requests
that assistance be se nt to the location.

vice information. They are well informed about the operation of all systems on your
vehicle.
●Keep a copy of the repair order. It proves that the maintenance that has been per-
formed is under warranty coverage. If any problem should arise while your vehicle is
under warranty, your Lexus dealer will promptly take care of it.

When trouble arises
Start the engine of the second vehicle. Increase the engine speed slightly and
maintain at that level for approximately 5 minutes to recharge the battery of
your vehicle.
Open and close any of the doors of your vehicle with the engine switch off.
Maintain the engine speed of the second vehicle and start the engine of your
vehicle by turning the engine switch to IGNITION ON mode.
Once your vehicle’s engine has started, remove the jumper cables in the exact
reverse order in which they were connected.
Once the engine starts, have the vehicle checked at your Lexus dealer as soon
as possible.
■Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
■To prevent battery discharge
●Turn off the headlights and the audio system while the engine is off.
●Turn off any unnecessary electrical components when the vehicle is running at a low
speed for an extended period, such as in heavy traffic.
■Charging the battery
The electricity stored in the battery will discharge gradually even when the vehicle is not
in use, due to natural discharg e and the draining effects of certain electrical appliances. If
the vehicle is left for a long time, the battery may discharge, and the engine may be
unable to start. (The battery recharges automatically during driving.)
■When recharging or replacing the battery
●Make sure that the key is not inside the vehicle when recharging or replacing the bat-
tery. The key may be locked in the vehicle if the alarm is activated. ( P. 7 1 )
●In some cases, it may not be possible to unlock the doors using the smart access system
with push-button start when the battery is discharged. Use the wireless remote control
or the mechanical key to lock or unlock the doors.
●The engine may not start on the first attempt after the battery has recharged but will
start normally after the second attempt. This is not a malfunction.
●The engine switch mode is memorized by the vehicle. When the battery is recon-
nected, the system will return to the mode it was in before the battery was discharged.
Before disconnecting the battery, turn the engine switch off. If you are unsure what
mode the engine switch was in before the battery discharged, be especially careful
when reconnecting the battery.
