Jump Starting
The 12 Volt auxiliary battery may be jump started if the vehicle does not start
and the instrument cluster gauges are dim or off after depressing the brake
pedal and pushing the power button.
The 12 Volt auxiliary battery is located in the trunk. If the 12 Volt auxiliary
battery is discharged, instead of using the metal cut key to open the trunk and
access the auxiliary battery, it is easier to jump start the vehicle by accessing
the remote positive 12 Volt auxiliary battery terminal in the engine
compartment fuse box.
•
Remove the fuse box cover, and open the positive terminal cover.
•
Connect the positive jumper cable to the positive terminal.
•
Connect the negative jumper cable to a solid ground.
•
Place the smart key in proximity to the interior of the vehicle, depress the
brake pedal, and push the power button.
NOTE:
If the vehicle does not recognize the smart key after connecting the
booster battery to the vehicle, open and close the driver door when the
vehicle is shut off.
If the smart key internal battery is dead, touch the Lexus emblem side of
the smart key to the power button during the start sequence. See the
instructions and illustrations on page 8 for more details.
•
The high voltage HV battery pack cannot be jump started.
Immobilizer & Anti-Theft Alarm
The HS250h is equipped with a standard immobilizer system and an anti-theft
alarm.
•
The vehicle can be started only with a registered smart key.
•
To disarm the anti-theft alarm, unlock the door by using the smart key
button, hidden metal cut key, or door handle touch sensor. Turning the
ignition-on or starting the vehicle will also disarm the anti-theft alarm.
