When trouble arises
GS F
Connect a positive jumper cable clamp to the positive (+) battery terminal
on your vehicle
Connect the clamp on the other end of the positive cable to the positive (+)
battery terminal on the second vehicle
Connect a negative cable clamp to the negative (-) battery terminal on the
second vehicle
Connect the clamp at the other end of the negative cable to a solid, station-
ary, unpainted metallic point away from the battery and any moving parts,
as shown in the illustration.
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 the engine has started, remove the jumper cables in the exact reverse
order from which they were connected.
Once the engine starts, have the vehicle inspected at your Lexus dealer as soon
as possible.
