FREEING A FROZEN DOOR LOCKY51D-V-E01-5EBECC5D-B5CD-4CE7-A4D7-6E52DD8EBEECTo prevent a door lock from freezing, apply
deicer through the key hole. If the lock
becomes frozen, heat the key before
inserting it into the key hole or use the
Intelligent Key system.
ANTIFREEZEY51D-V-E01-7CABC06B-2D45-45D5-A042-B13E6F03CC5EIn the winter when it is anticipated that the
outside temperature will drop below 328F
(08C), check antifreeze to assure proper
winter protection. For additional informa-
tion, see “Engine cooling system” (P.8-12).
BATTERYY51D-V-E01-48005E45-813C-44A5-8D41-9521223F2001If the battery is not fully charged during
extremely 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.8-20).
DRAINING OF COOLANT WATERY51D-V-E01-A0F702CC-5DF7-4D12-BDDC-B53438BDF4C1If the vehicle is to be left outside without
antifreeze, drain the cooling system, in-
cluding the engine block. Refill before
operating the vehicle. For details, see
“Engine cooling system” (P.8-12).
TIRE EQUIPMENTY51D-V-E01-B6FA169D-58DD-435F-9AD5-F0E503886684SUMMER 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.
Consult an INFINITI retailer 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 prohi-
bit 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.8-43).
For all-wheel driveY51D-V-E01-52FA104E-DAD0-44AC-B200-A57E40801427If you install snow tires, they must also be
the same size, brand, construction and
tread pattern on all four wheels.

SPECIAL WINTER EQUIPMENTY51D-V-E01-FD3A51BB-C337-4BB2-A247-49F856B8CB20It is recommended that the following items
be carried in the vehicle during winter:
.A scraper and stiff-bristled brush to
remove 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 window washer fluid to refill the
reservoir tank.
DRIVING ON SNOW OR ICEY51D-V-E01-66431155-62BF-4354-8807-8F4097602234
WARNING
. Wet ice (328F, 08C 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)
Y51D-V-E01-F270A1FF-C9B0-43A5-AB8A-F0C23F1ADF65Engine block heaters are used to assist in
cold temperature starting.
The engine block heater should be used
when the outside temperature is 208F
(−78C) or lower.
To use the engine block heaterY51D-V-E01-79B81556-127B-4048-8AA9-6FD28CD83F1B1. 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.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected,
grounded 110-volt AC (VAC) outlet.
5. The engine block heater must be
plugged in for at least 2 - 4 hours,
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.

Y51D-V-E01-9ECDEC9C-D91E-43BE-8956-65EFDD4A98EF
CAUTION
.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 radiator cap while the
engine is still hot. When the radiator cap
is removed, pressurized 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 move the
shift lever to the P (Park) position.
Do not stop the engine.
2. Turn off the climate control. Open all the windows, move the heater or air
conditioner temperature control to
maximum hot and fan control to high speed.
3. If engine overheating is caused by
climbing a long hill on a hot day, run
the engine at a fast idle (approximately
1,500 rpm) until the temperature gauge
indication returns to normal.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from the
radiator 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 engine,
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 cool-
ant is leaking 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 thecoolant level in the reservoir tank with
the engine running. Add coolant to the
reservoir tank if necessary. Have your
vehicle repaired at the nearest INFINITI
retailer.

8-4Maintenance and do-it-yourself
securely. Check the belt webbing for cuts,
fraying, wear or damage.
Seats:Check seat position controls such as
seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and that all
latches lock securely in every position.
Check that the head restraints move up
and down smoothly and that the locks (if
so equipped) hold securely in all latched
positions.
Steering wheel: Check for changes in the
steering conditions, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure that
all warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check that
the wipers and washer operate properly
and that the wipers do not streak.
Under the hood and vehicleY51D-V-E01-B3361551-A047-4A72-ACCF-65F901F88160The maintenance items listed here should
be checked periodically (for example, each
time you check the engine oil or refuel). Battery*:
Check the fluid level in each cell.
It should be between the MAX and MIN
lines. Vehicles operated in high tempera-
tures or under severe condition require
frequent checks of the battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1. Installation or extended use of electro-
nic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
Brake fluid level*: Make sure that the
brake fluid level is between the MAX and
MIN lines on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure that no belt
is frayed, worn, cracked or oily.
Engine oil level*: Check the level after parking the vehicle on a level spot and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the oil
pan.
Exhaust system:
Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, im-
mediately have the exhaust system in-
spected by an INFINITI retailer. (See
“Precautions when starting and driving”
(P.5-3) for exhaust gas (Carbon monoxide).)
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use
is normal. If you should notice any leaks or
if gasoline fumes are evident, check for the
cause and have it corrected immediately.
Power steering fluid level* and lines:
Check the level when the fluid is cold,
with the engine off. Check the lines for
proper attachment, leaks, cracks, etc.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks,
deformation, rot or loose connections.
Condition:
