FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
de-icer through the key hole. If the lock be-
comes frozen, heat the key before inserting it
into the key hole, or use the INFINITI Intelli-
gent Key.
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper winter
protection. For additional information, see
“Engine cooling system” (P. 8-4).
BATTERY
If the battery is not fully charged during ex-
tremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery
should be checked regularly. For additional
information, see “Battery” (P. 8-13).
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For additional information, see
“Changing engine coolant” (P. 8-5).

COLD WEATHER DRIVING
5-184Starting and driving

To shut off the engine in an emergency situ-
ation while driving, perform the following
procedure:
– Rapidly push the push-button ignitionswitch three consecutive times in less than
1.5 seconds, or
– Push and hold the push-button ignition switch for more than 2 seconds.TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with 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 information display,
one or more of your tires is significantly
under-inflated. If equipped, the system also
displays pressure of all tires (except the spare
tire) on the display screen by sending a signal
from a sensor that is installed in each wheel. If
the vehicle is being driven with low tire pres-
sure, 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 additional information, see “Warning
lights, indicator lights and audible reminders”
(P. 2-12) and “Tire Pressure Monitoring Sys-
tem (TPMS)” (P. 5-5).
WARNING
• Radio waves could adversely affect elec-
tric medical equipment. Those who use a
pacemaker should contact the electric
medical equipment manufacturer for the
possible influences before use. •
If the low tire pressure warning light illu-
minates while driving, avoid sudden
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 recom-
mended 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 or the TPMS may be
malfunctioning. If you have a flat tire,
replace it with a spare tire as soon as
possible, If no tire is flat and all tires are
properly inflated, have the vehicle
checked. It is recommended that you
visit an INFINITI retailer for this service.

3. Turn off the air conditioner. Open all thewindows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from the radia-
tor before opening the hood. If steam or
coolant is escaping, turn off the engine.
Do not open the hood further until no
steam or coolant can be seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine, stand clear to prevent getting
burned.
6. Visually check drive belts for damage or looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leaking,
the water pump belt is missing or loose, or
the cooling fan does not run, stop the
engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling fan
can start at any time.
7. After the engine cools down, check the coolant level in the engine coolant reser-
voir tank with the engine running. Add
coolant to the engine coolant reservoir
tank if necessary. Have your vehicle re-
paired. It is recommended that you visit an
INFINITI retailer for this service. When towing your vehicle, all jurisdictional
and local regulations for towing must be fol-
lowed. Incorrect towing equipment could
damage your vehicle. Towing instructions are
available from an INFINITI retailer. Local ser-
vice operators are generally familiar with the
applicable laws and procedures for towing.
To assure proper towing and to prevent ac-
cidental damage to your vehicle, INFINITI
recommends having a service operator tow
your vehicle. It is advisable to have the service
operator carefully read the following
precautions:
WARNING
• Never ride in a vehicle that is being
towed.
• Never get under your vehicle after it has
been lifted by a tow truck.
CAUTION
• When towing, make sure that the trans-
mission, axles, steering system and pow-
ertrain are in working condition. Use dol-
lies or flatbed if any of the listed systems
are not working.
• Always attach safety chains before
towing.

CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir when
the engine is cold. If the coolant level is below
the MIN level
OB, add coolant to the MAX
level
OA. If the reservoir is empty, check the
coolant level in the radiator when the engine
is cold. If there is insufficient coolant in the
radiator, fill the radiator with coolant up to
the filler opening and also add it to the reser-
voir up to the MAX level
OA. This vehicle contains Genuine NISSAN Long
Life Antifreeze/Coolant (blue). The life ex-
pectancy of the factory-fill coolant is
105,000 miles (168,000 km) or 7 years.
Mixing any other type of coolant that is not
equivalent to Genuine NISSAN Long Life
Antifreeze/Coolant (blue), or the use of non-
distilled water will reduce the life expectancy
of the factory-fill coolant. For additional in-
formation, see the "Maintenance and sched-
ules" section of this manual.
If the cooling system frequently requires
coolant, have it checked. It is recommended
that you visit an INFINITI retailer for this
service.
For additional information on the location of
the engine coolant reservoir, see “Engine
compartment check locations” (P. 8-3).
CHANGING ENGINE COOLANT
An INFINITI retailer can change the engine
coolant. The service procedure can be found
in the INFINITI Service Manual.
Improper servicing can result in reduced
heater performance and engine overheating.
WARNING
• To avoid the danger of being scalded,
never change the coolant when the en-
gine is hot.
• Never remove the radiator or engine
coolant reservoir cap when the engine is
hot. Serious burns could be caused by
high pressure fluid escaping from the
radiator.
• Avoid direct skin contact with used cool-
ant. If skin contact is made, wash thor-
oughly with soap or hand cleaner as soon
as possible.
• Keep coolant out of the reach of children
and pets.
Engine coolant must be disposed of properly.
Check your local regulations.
