Interior features
Use the front passenger footwell hooks
to help support and prevent objects
placed on the floor, such as a grocery
bag, from overturning.
NOTICE
To avoid damaging the power outlet, close the power outlet lid when the power outlet
is not in use.
Foreign objects or liquids that enter the power outlet may cause a short circuit.
To prevent blown fuse, do not use a 120 VAC appliance that requires more than
100 W.
If a 120 VAC appliance that consumes more than 100 W is used, the protection cir-
cuit will cut the power supply.
To prevent battery discharge, do not use the power outlet longer than necessary
when the engine is off.
The following 120 VAC appliances may not operate properly even if their power con-
sumption is under 100W:
Appliances with high initial peak wattage
Measuring devices that process precise data
Other appliances that require an extremely stable power supply
Front passenger footwell hooks
NOTICE
To prevent the hooks from being damaged, do not hang anything from a hook or apply
excessive force to it.

If the replaced fuse blows again, have the vehicle inspected by your Lexus dealer.
If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.
When replacing light bulbs
Lexus recommends that you use genuine Lexus products designed for this vehicle.
Because certain bulbs are connected to circuits designed to prevent overload, nongenu-
ine parts or parts not designed for this vehicle may be unusable.

When trouble arises
One of the following may be the cause of the problem:
The electronic key may not be functioning properly.
(
P. 564)
There may not be sufficient fuel in the vehicle’s tank.
Refuel the vehicle.
There may be a malfunction in the immobilizer system. (
P. 85)
There may be a malfunction in the steering lock system.
The hybrid system may be malfunctioning due to an electrical problem such
as electronic key battery depletion or a blown fuse. However, depending on
the type of malfunction, an interim measure is available to start the hybrid sys-
tem. (
P. 562)
One of the following may be the cause of the problem:
The 12-volt battery may be discharged. (
P. 568)
The 12-volt battery terminal connections may be loose or corroded.
(
P. 483)
If the hybrid system will not start
Reasons for the hybrid system not starting vary depending on the situation.
Check the following and perform the appropriate procedure:
The hybrid system will not start even though the correct starting proce-
dure is being followed. (
P. 232)
The interior lights and headlights are dim, or the horn does not sound or
sounds at a low volume.

7-2. Steps to take in an emergency
If you have a set of jumper (or booster) cables and a second vehicle with a 12-volt
battery, you can jump start your vehicle by following the steps below.
Confirm that the electronic key is
being carried.
When
connecting
the
jumper
(or
booster) cables, depending on the situa-
tion, the alarm may activate and doors
locked. (
P. 88)
Open the hood (
P. 473) and fuse
box cover.
Open the exclusive jump starting
terminal cover.
If the 12-volt battery is discharged
The following procedures may be used to start the hybrid system if the vehi-
cle’s 12-volt battery is discharged.
You can also call your Lexus dealer or a qualified repair shop.

7-2. Steps to take in an emergency
Start the engine of the second vehicle. Increase the engine speed slightly and
maintain at that level for approximately 5 minutes to recharge the 12-volt bat-
tery of your vehicle.
Open and close any of the doors of your vehicle with the power switch off.
Maintain the engine speed of the second vehicle and start the hybrid system
of your vehicle by turning the power switch to ON mode.
Make sure the “READY” indicator comes on. If the indicator light does not
come on, contact your Lexus dealer.
Once the hybrid system has started, remove the jumper cables in the exact
reverse order from which they were connected.
Close the exclusive jump starting terminal cover, and reinstall the fuse box
cover to its original position.
Once the hybrid system starts, have the vehicle inspected at your Lexus dealer
as soon as possible.
Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
To prevent 12-volt battery discharge
Turn off the headlights and the audio system while the hybrid system 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 12-volt battery
The electricity stored in the 12-volt battery will discharge gradually even when the vehicle
is not in use, due to natural discharge and the draining effects of certain electrical appli-
ances. If the vehicle is left for a long time, the 12-volt battery may discharge, and the
hybrid system may be unable to start. (The 12-volt battery recharges automatically while
the hybrid system is operating.)
When the 12-volt battery is removed or discharged
In some cases, it may not be possible to unlock the doors using the smart access system
with push-button start when the 12-volt battery is discharged. Use the wireless remote
control or the mechanical key to lock or unlock the doors.
The hybrid system may not start on the first attempt after the 12-volt battery has
recharged but will start normally after the second attempt. This is not a malfunction.
The power switch mode is memorized by the vehicle. When the 12-volt battery is
reconnected, the system will return to the mode it was in before the 12-volt battery was
discharged. Before disconnecting the 12-volt battery, turn the power switch off.
If you are unsure what mode the power switch was in before the 12-volt battery dis-
charged, be especially careful when reconnecting the 12-volt battery.
The power back door must be initialized. (
