Before attempting to jump start the vehi-
cle, make sure the fuel tank is not empty
and the correct starting procedure is
followed. See“Starting the INFINITI Direct
Response Hybrid
®System” (P.5-14). Do
not drive the vehicle on battery power only
if the fuel tank is empty. The Lithium ion
(Li-ion) battery will become discharged and
the INFINITI Direct Response Hybrid
®Sys-
tem will turn off.
CONFIRM BATTERY IS DISCHARGED
If any of the following conditions occurs,
the 12-volt battery might discharged:
. The instrument cluster and/or head-
lights are not normal brightness.
. Audio accessories cannot be turned on.
. The hybrid system does not become
READY to drive mode.
. The ignition switch cannot be placed in
the ON position.
Check the following if you notice above
conditions.
1. Check that the 12-volt battery terminals are tight and clean. See “12-volt
battery” (P.8-17). The 12-volt battery
is located on the left hand side of the
trunk behind an access panel. If the 12-
volt battery terminals are loose, contact your INFINITI retailer.
2. If the 12-volt battery terminals are tight and clean, try to jump start the vehicle.
See “Jump starting” (P.6-5).
If the hybrid system still does not start,
contact an INFINITI retailer. To start your INFINITI Direct Response
Hybrid
®System with a booster battery,
the instructions and precautions below
must be followed.
Jump starting provides power to the 12 volt
system to allow the electrical systems to
operate. The electrical systems must be
operating to allow the Lithium ion (Li-ion)
battery to be charged. Jump starting does
not charge the Li-ion battery.
WARNING
. If done incorrectly, jump starting can
lead to a 12-volt battery explosion,
resulting in severe injury or death. It
could also damage your vehicle.
. Explosive hydrogen gas is always pre-
sent in the vicinity of the 12-volt battery.
Make sure that the vent tube is
mounted.
. Do not allow battery fluid to come into
contact with eyes, skin, clothing or
painted surfaces. Battery fluid is a
corrosive sulfuric acid solution which
can cause severe burns. If the fluid
should come into contact with anything,
immediately flush the contacted area
with water.

IF THE VEHICLE DOES NOT START JUMP STARTING
8-18Maintenance and do-it-yourself
for at least 15 minutes and seek medical
attention.
. The hybrid vehicle uses a special bat-
tery. If the 12-volt battery needs to be
replaced, use a 12-volt battery of the
same design. Using the wrong battery
can cause hydrogen gas to build up in
the vehicle, which could lead to an
explosion and personal injury.
. When working on or near a 12-volt
battery, always wear suitable eye pro-
tection and remove all jewelry.
. Battery posts, terminals and related
accessories contain lead and lead com-
pounds. Wash hands after handling.
. Keep the 12-volt battery out of the reach
of children.
