SEDAN AND COUPE
WARNING
. Do not expose the battery to flames or
electrical sparks. Hydrogen gas gener-
ated by the battery is explosive. Do not
allow battery fluid to contact your skin,
eyes, fabrics, or painted surfaces. After
touching a battery or battery cap, do not
touch or rub your eyes. Thoroughly wash your hands. If the acid contacts your
eyes, skin or clothing, immediately flush
with water for at least 15 minutes and
seek medical attention.
. Do not operate the vehicle if the fluid in
the battery is low. Low battery fluid can
cause a higher load on the battery which
can generate heat, reduce battery life,
and in some cases lead to an explosion.
. When working on or near a battery,
always wear suitable eye protection and
remove all jewelry.
. Battery posts, terminals and related
accessories contain lead and lead com-
pounds. Wash hands after handling.
. Keep the battery out of the reach of
children.

Vehicles operated in high temperatures or
under severe conditions require frequent
checks of the battery fluid level.
JUMP STARTING
If jump starting is necessary, see “Jump
starting” (P.6-8). If the engine does not
start by jump starting, the battery may
have to be replaced. Contact an INFINITI
retailer.

CAUTION
.Do not ground accessories directly to the
battery terminal. Doing so will bypass
the variable voltage control system and
the vehicle battery may not charge
completely.
. Use electrical accessories with the en-
gine running to avoid discharging the
vehicle battery.
The variable voltage control system mea-
sures the amount of electrical discharge
from the battery and controls voltage
generated by the generator.SDI2117

INTELLIGENT KEY BATTERY REPLACEMENT

A vehicle equipped with All-Wheel Drive
(AWD) should never be tested using a two
wheel dynamometer (such as the dynam-
ometers used by some states for emissions
testing), or similar equipment. Make sure
you inform test facility personnel that your
vehicle is equipped with AWD before it is
placed on a dynamometer. Using the
wrong test equipment may result in trans-
mission damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury.
Due to legal requirements in some states/
areas, your vehicle may be required to be
in what is called the“ready condition”for
an Inspection/Maintenance (I/M) test of
the emission control system.
The vehicle is set to the “ready condition”
when it is driven through certain driving
patterns. Usually, the “ready condition”
can be obtained by ordinary usage of the
vehicle.
If a powertrain system component is
repaired or the battery is disconnected,
the vehicle may be reset to a “not ready
condition” . Before taking the I/M test,
check the vehicle’ s inspection/mainte-
nance test readiness condition. Place the
ignition switch in the ON position without starting the engine. If the Malfunction
Indicator Light (MIL) comes on steady for
20 seconds and then blinks for 10
seconds, the I/M test condition is
“not
ready”. If the MIL does not blink after 20
seconds, the I/M test condition is “ready”.
Contact an INFINITI retailer to set the
“ready condition” or to prepare the vehicle
for testing. This vehicle is equipped with an Event
Data Recorder (EDR). The main purpose of
an EDR is to record, in certain crash or
near crash-like situations, such as an air
bag deployment or hitting a road obstacle,
data that will assist in understanding how
a vehicle’s systems performed. The EDR is
designed to record data related to vehicle
dynamics and safety systems for a short
period of time, typically 30 seconds or
less. The EDR in this vehicle is designed to
record such data as:
.
How various systems in your vehicle
were operating;
. Whether or not the driver and passen-
ger safety belts were buckled/fas-
tened;
. How far (if at all) the driver was
depressing the accelerator and/or
brake pedal; and,
. How fast the vehicle was traveling.
. Sounds are not recorded.
These data can help provide a better
understanding of the circumstances in
which crashes and injuries occur. NOTE:
EDR data are recorded by your vehicle only
if a nontrivial crash situation occurs; no
data are recorded by the EDR under normal
driving conditions and no personal data
