Key LOCK warning
The information is displayed and a buzzer
sounded to remind the driver to place the
ignition switch in the OFF position to avoid a
discharged battery.
The message can be cleared by placing the
ignition switch in the OFF position (or
restarting the engine) or pushing the
orswitch on the steering wheel.

System fault
This message is displayed when the Idling
Stop System is malfunctioning.
It is recommended you have the system
checked by an INFINITI retailer.

IDLING STOP OFF SWITCH
The system can be temporarily deactivated
by pushing the Idling Stop OFF switch.
Pushing the switch again or restarting the
engine by using the ignition switch will
reactivate the Idling Stop System.
.When the Idling Stop System is deacti-
vated while the engine is running, the
engine is prevented from automatically
stopping.
. When the Idling Stop System is deacti-
vated after the engine has been auto-
matically stopped by the Idling Stop
System, the engine will immediately
restart if suitable conditions are present.
The engine will then be prevented from

automatically stopping during the same
journey.
. Whenever the Idling Stop System is
deactivated the indicator light
on the
Idling Stop OFF switch illuminates. In
this condition the Idling Stop System
cannot prevent unnecessary fuel con-
sumption, exhaust emissions, or noise
during your journey.
. If the Idling Stop System is malfunction-
ing, the indicator light
on the Idling
Stop OFF switch illuminates.
NOTE:
The Idling Stop System ON or OFF message
is displayed for a few seconds in the vehicle
information display when the Idling Stop
OFF switch is pushed. See “Idling Stop
System ON or OFF” (P.5-139).
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock
becomes frozen, heat the key before insert-
ing it into the key hole or use the Intelligent
Key system.
ANTIFREEZE
In the winter when it is anticipated that the
outside temperature will drop below 32°F
(0°C), check antifreeze to assure proper
winter protection. For additional informa-
tion, see “Engine cooling system (for
VR30DDTT engine models)” (P.8-6), “En-
gine cooling system (for 2.0L turbo gasoline
engine models)” (P.8-8) or “Intercooler cool-
ing system (for VR30DDTT engine models)”
(P.8-9).
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the bat-
tery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly. For
additional information, see “Battery” (P.8-
16).
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, includ-
ing the engine block. Refill before operating
the vehicle. For details, see “Engine cooling
system (for VR30DDTT engine models)”
(P.8-6) or “Engine cooling system (for 2.0L
turbo gasoline engine models)” (P.8-8).
TIRE EQUIPMENT
SUMMER tires have a tread designed to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your
vehicle on snowy or icy roads, INFINITI
recommends the use of MUD & SNOW or
ALL SEASON tires on all four wheels. It is
recommended you consult an INFINITI re-
tailer for the tire type, size, speed rating and
availability information.
For additional traction on icy roads, studded
tires may be used. However, some U.S.
states and Canadian provinces prohibit their
use. Check local, state and provincial laws
before installing studded tires.
Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may be
poorer than that of non-studded snow tires.
Tire chains may be used. For details, see
“Tire chains” (P.8-40) of this manual.

6-2In case of emergency
SIC2574
Push the switch on to warn other drivers
when you must stop or park under emer-
gency conditions. All turn signal lights will
flash.
WARNING
.If stopping for an emergency, be sure
to move the vehicle well off the road.
. Do not use the hazard warning
flashers while moving on the highway
unless unusual circumstances force
you to drive so slowly that your
vehicle might become a hazard to
other traffic. .
Turn signals do not work when the
hazard warning flasher lights are on.
The flasher can be actuated with the ignition
switch in any position.
When an impact that could activate the
supplemental air bags is detected, the
hazard warning flasher lights blink automa-
tically. If the hazard warning flasher switch is
pushed, the hazard warning flashers will turn
off.
WARNING
Do not turn the hazard warning flasher
switch to off until you can make sure
that it is safe to do so. Also, the hazard
flasher warning may not blink automa-
tically depending on the force of impact.
Some state laws may prohibit the use of the
hazard warning flasher switch while driving. In the event of a roadside emergency,
Roadside Assistance Service is available to
you. Please refer to your Warranty Informa-
tion Booklet (U.S.) or Warranty & Roadside
Assistance Information Booklet (Canada) for
details.
HAZARD WARNING FLASHER SWITCHROADSIDE ASSISTANCE PROGRAM

To shut off the engine in an emergency
situation while driving, perform the follow-
ing procedure:
.Rapidly push the push-button ignition
switch 3 consecutive times in less than
1.5 seconds, or
. Push and hold the push-button ignition
switch for more than 2 seconds. If you have a flat tire, follow the instructions
in this section.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires except the
spare. When the low tire pressure warning
light is lit and the “Tire Pressure Low - Add
Air” warning appears in the vehicle informa-
tion display, one or more of your tires is
significantly under-inflated. If the vehicle is
being driven with low tire pressure, the
TPMS will activate and warn you of it by
the low tire pressure warning light. This
system will activate only when the vehicle is
driven at speeds above 16 MPH (25 km/h).
For more details, see “Warning lights, in-
dicator lights and audible reminders” (P.2-
10) and “Tire Pressure Monitoring System
(TPMS)” (P.5-5).
WARNING
.
Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment man-
ufacturer for the possible influences
before use. .
If the low tire pressure warning light
illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull
off the road to a safe location and
stop the vehicle as soon as possible.
Driving with under-inflated tires may
permanently damage the tires and
increase the likelihood of tire failure.
Serious vehicle damage could occur
and may lead to an accident and
could result in serious personal injury.
Check the tire pressure for all four
tires. Adjust the tire pressure to the
recommended COLD tire pressure
shown on the Tire and Loading
Information label to turn the low tire
pressure warning light OFF. If the
light still illuminates while driving
after adjusting the tire pressure, a
tire may be flat. If you have a flat tire,
replace it with a spare tire (if so
equipped).
. Since the spare tire is not equipped
with the TPMS, when a spare tire is
mounted or a wheel is replaced, the
TPMS will not function and the low
tire pressure warning light will flash
for approximately 1 minute. The light
will remain on after 1 minute. Have
your tires replaced and/or TPMS
system reset as soon as possible. It

cover the vent holes as it may be
contaminated with corrosive acid.
10. Put the battery cover and the engine cover back to the original location.
NOTE:
For 2.0L turbo gasoline engine models, if
the engine cannot be started after the
procedure above, the auxiliary battery
may be discharged. Connect the jumper cables to the auxiliary battery and apply
the procedure shown in “Auxiliary battery
(for 2.0L turbo gasoline engine models)”
(P.6-14).
