Jump-Start Procedures - Lexus IS-F 2008 Towing And Road Service Manual

JUMP-STARTING:
The Lexus IS-F has one battery which is located under the hood. It is positioned on the
right (passenger's) side of the engine compartment near the firewall, windshield area.
The following jump-starting procedures should be followed when rendering assistance to
a Lexus IS-F vehicle. Pay special attention to the position of the positive and negative
battery post as they are not well labeled and can be difficult to tell apart in areas of
reduced visibility:
x Never use jump-starting equipment that can exceed normal 12-volt charging
system voltage.
x Ensure that all electrical accessories and the ignition switch are turned OFF
before connecting jumper cables or a jumper box to the discharged vehicle.
Connecting the jumper cables.
1. Remove the engine cover.
This can be somewhat difficult and can result in damage to the engine cover if
the retaining clips for the engine cover are not released properly. The following
diagram shows where the cover clips/bolts are located and how to release them
without damage.
