One of the following may be the cause of the problem:
●The electronic key may not be functioning properly. ( P. 514)
● There may not be sufficient fuel in the vehicle’s tank.
Refuel the vehicle.
● There may be a malfunction in the immobilizer system. (P. 9 1 )
● There may be a malfunction in the steering lock system.
● The hybrid system may be malfunctioning due to an electrical prob-
lem such as electronic key battery depletion or a blown fuse. How-
ever, depending on the type of malfunction, an interim measure is
available to start the hybrid system. ( P. 511)
One of the following may be the cause of the problem:
● The 12-volt battery may be discharged. ( P. 516)
● The 12-volt battery terminal conn ections may be loose or corroded.
If the hybrid system will not star t
Reasons for the hybrid system not starting vary depending on
the situation. Check the follo wing and perform the appropriate
procedure:
The hybrid system will not start even though the correct starting
procedure is being followed. ( P. 229)
The interior lights and headlights are dim, or the horn does not
sound or sounds at a low volume.

When trouble arises
HIGHLANDER_HV_U (OM48D74U)
One of the following may be the cause of the problem:
●One or both of the 12-volt batter y terminals may be disconnected.
● The 12-volt battery may be discharged. ( P. 516)
Contact your Toyota dealer if the problem cannot be repaired, or if repair
procedures are unknown.
When the hybrid system does not start, the following steps can be
used as an interim measure to st art the hybrid system if the power
switch is functioning normally:
Set the parking brake.
Shift the shift lever to P.
Turn the power switch to ACCESSORY mode.
Press and hold the power switch for about 15 seconds while
depressing the brake pedal firmly.
Even if the hybrid system can be started using the above steps, the
system may be malfunctioning. Have the vehicle inspected by your
Toyota dealer.
The interior lights and headlight s do not turn on, or the horn
does not sound.

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.
When installing, first hook the fuse box cover onto the two rear tabs.
Once the hybrid system starts, have the vehicle inspected at your
Toyota dealer as soon as possible.
■ Starting the hybrid system when th e 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.
■ When recharging or repl acing the 12-volt battery
● In some cases, it may not be possible to unlock the doors using the smart
key system 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 bat-
tery 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 bat-
tery discharged, be especially careful when reconnecting the 12-volt battery.
● The power back door must be initialized. ( P. 567)
■ 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 appliances. 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.)
