5-2. Steps to take in an emergency
The following procedures may be used to start the engine in the event the
vehicle’s battery is discharged.
You can call your Lexus dealer, Roadside Assistance or Lexus Customer Ser-
vice Assistance.
If you have a set of jumper (or booster) cables and a second vehicle with a
12-volt battery, you can jump start your Lexus following the steps below.
Connecting the jumper cables.
If required, remove all vent plugs
from the booster battery. Lay a
cloth over the open vents on the
booster battery. (This helps reduce
the explosion hazard, personal
injuries and burns.)
Positive (+) battery terminal on
your vehicle.
Positive (+) battery terminal on
the second vehicle.
Negative (-) battery terminal on
the second vehicle.
Connect the jumper cables to
ground on your vehicle as shown
in the illustration.
Start the engine of the second vehicle.
Increase the engine speed slightly and maintain at that level for
approximately five minutes.
