SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
• A scraper and stiff-bristled brush to re-move ice and snow from the windows and
wiper blades.
• A sturdy, flat board to be placed under the jack to give it firm support.
• A shovel to dig the vehicle out of snowdrifts.
• Extra washer fluid to refill the windshield- washer fluid reservoir.
DRIVING ON SNOW OR ICE
WARNING
• Wet ice (32°F, 0°C and freezing rain),
very cold snow or ice can be slick and very
hard to drive on. The vehicle will have
much less traction or “grip” under these
conditions. Try to avoid driving on wet
ice until the road is salted or sanded.
• Whatever the condition, drive with cau-
tion. Accelerate and slow down with
care. If accelerating or downshifting too
fast, the drive wheels will lose even more
traction. •
Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pavement.
• Allow greater following distances on
slippery roads.
• Watch for slippery spots (glare ice).
These may appear on an otherwise clear
road in shaded areas. If a patch of ice is
seen ahead, brake before reaching it. Try
not to brake while on the ice, and avoid
any sudden steering maneuvers.
• Do not use the cruise control on slippery
roads.
• Snow can trap dangerous exhaust gases
under your vehicle. Keep snow clear of
the exhaust pipe and from around your
vehicle.
ENGINE BLOCK HEATER (if so
equipped)
Engine block heaters are used to assist with
cold temperature starting.
The engine block heater should be used when
the outside temperature is 20°F (-7°C) or
lower.
WARNING
• Do not use your engine block heater with
an ungrounded electrical system or a
2-pronged adapter. You can be seriously
injured by an electrical shock if you use
an ungrounded connection.
• Disconnect and properly store the engine
block heater cord before starting the en-
gine. Damage to the cord could result in
an electrical shock and can cause serious
injury.
• Use a heavy-duty 3-wire, 3-pronged ex-
tension cord rated for at least 10 A. Plug
the extension cord into a Ground Fault
Interrupt (GFI) protected, grounded
110-VAC outlet. Failure to use the
proper extension cord or a grounded
outlet can result in a fire or electrical
shock and cause serious personal injury.
To use the engine block heater:
1. Turn the engine off.
2. Open the hood and unwrap the engine block heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged extension
cord.
5-166Starting and driving

4. Plug the extension cord into a GroundFault Interrupt (GFI) protected, grounded
110-volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least2-4hours, depending on
outside temperatures, to properly warm
the engine coolant. Use an appropriate
timer to turn the engine block heater on.
6. Before starting the engine, unplug and properly store the cord to keep it away
from moving parts.
ACTIVE NOISE CANCELLATIONThis system uses microphonesO1located
inside the vehicle to detect engine booming
noise. The system then automatically gener-
ates a noise canceling sound through the
speakers and woofer (if so equipped) to re-
duce engine booming noise.
NOTE:
To operate the active noise cancellation
system properly:
• Do not cover the speakers or woofer (if so equipped).
• Do not cover the microphones.

WARNING
Always follow the instructions below. Fail-
ure to do so could result in damage to the
charging system and cause personal injury.
1. If the booster battery is in another vehicle, position the 2 vehicles to bring their bat-
teries near each other.
Do not allow the two vehicles to touch.
2. Apply the parking brake. Engage the P (Park) position. Switch off all unnecessary
electrical systems (lights, heater, air con-
ditioner, etc.). 3. Place the ignition switch to the OFF
position.
4. Connect the jumper cables in the se- quence illustrated (
OA,OB,OC,OD).
CAUTION
• Always connect positive (+) to positive
(+) and negative (−) to body ground (for
example, strut mounting bolt, engine lift
bracket, etc.) — not to the battery.
• Make sure the jumper cables do not
touch moving parts in the engine com-
partment and that the cable clamps do
not contact any other metal. 5. Start the engine of the booster vehicle and
let it run for a few minutes.
6. Keep the engine speed of the booster ve- hicle at about 2,000 rpm and start the
engine of the vehicle being jump started.
CAUTION
Do not keep the starter motor engaged for
more than 10 seconds. If the engine does
not start right away, place the ignition
switch in the OFF position and wait 3 to 4
seconds before trying again.
7. After starting the engine, carefully discon- nect the negative cable and then the posi-
tive cable.

CAUTION
• Continuously Variable Transmission
(CVT) models cannot be push-started or
tow-started. Attempting to do so may
cause transmission damage.
• Do not push start this vehicle. The three-
way catalyst may be damaged.WARNING
• Do not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or a vehicle fire.
• To avoid the danger of being scalded,
never remove the coolant reservoir cap
while the engine is still hot. When the
coolant reservoir cap is removed, pres-
surized hot water will spurt out, possibly
causing serious injury.
• Do not open the hood if steam is coming
out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading),
or if you feel a lack of engine power, detect
abnormal noise, etc. take the following steps.
1. Move the vehicle safely off the road, apply the parking brake and engage the P (Park)
position.
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed. 3. 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.
4. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine, stand clear to prevent getting
burned.
5. 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.

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.
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 or the use of
non-distilled water will reduce the life expec-
tancy of the factory-fill coolant. For addi- tional information, see "Maintenance and
schedules" (P. 9-2).
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 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.
