WARNING
. The air conditioner cooling function
operates only when the engine is run-
ning.
. Do not leave children or adults who
would normally require the support of
others alone in your vehicle. Pets should
not be left alone either. On hot, sunny
days, temperatures in a closed vehicle
could quickly become high enough to
cause severe or possibly fatal injuries to
people or animals.
. Do not use the recirculation mode for
long periods as it may cause the interior
air to become stale and the windows to
fog up.
Start the engine and operate the automatic
climate control system.
When the “STATUS”button is pushed, the
automatic climate control status screen
will appear. (See “How to use STATUS
button” earlier in this section.)

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
inserting 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 328F
(08C), check antifreeze to assure proper
winter protection. For additional informa-
tion, see“Engine cooling system” in the
“8. Maintenance and do-it-yourself” sec-
tion.
BATTERY
If 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”in
the “8. Maintenance and do-it-yourself”
section .
DRAINING OF COOLANT WATER
If 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” in the“8. Main-
tenance and do-it-yourself” section.
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.
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”
in the“8. Maintenance and
do-it-yourself” section of this manual.
For all-wheel drive
If you install snow tires, they must also be
the same size, brand, construction and
tread pattern on all four wheels.
SPECIAL WINTER EQUIPMENT
It 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.
COLD WEATHER DRIVING

6-8In case of emergency
.The T-type spare tire and small size
spare tire are designed for emergency
use. See specific instructions under the
heading “Wheels and tires” in the“8.
Maintenance and do-it-yourself” section.To start your engine with a booster battery,
the instructions and precautions below
must be followed.
WARNING
.If done incorrectly, jump starting can
lead to a battery explosion, resulting in
severe injury or death. It could also
damage your vehicle.
. Explosive hydrogen gas is always pre-
sent in the vicinity of the battery. Keep
all sparks and flames away from the
battery.
. Do not allow battery fluid to come into
contact with eyes, skin, clothing or
painted surfaces. Battery fluid is a
corrosive sulphuric acid solution which
can cause severe burns. If the fluid
should come into contact with anything,
immediately flush the contacted area
with water.
. Keep the battery out of the reach of
children.
. The booster battery must be rated at 12
volts. Use of an improperly rated battery
can damage your vehicle. .
Whenever working on or near a battery,
always wear suitable eye protectors (for
example, goggles or industrial safety
spectacles) and remove rings, metal
bands, or any other jewelry. Do not lean
over the battery when jump starting.
. Do not attempt to jump start a frozen
battery. It could explode and cause
serious injury.
. Your vehicle has an automatic engine
cooling fan. It could come on at any time.
Keep hands and other objects away from
it.
JUMP STARTING

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. When towing your vehicle, all State (Pro-
vincial in Canada) and local regulations for
towing must be followed. Incorrect towing
equipment could damage your vehicle.
Towing instructions are available from an
INFINITI retailer. Local service operators are
familiar with the applicable laws and
procedures for towing. To assure proper
towing and to prevent accidental damage
to your vehicle, INFINITI recommends that
you have a service operator tow your
vehicle. It is advisable to have the service
operator carefully read the following pre-
cautions.
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
powertrain are in working condition. If
any unit is damaged, dollies must be

VEHICLE RECOVERY (freeing a stuck
vehicle)
WARNING
.Stand clear of a stuck vehicle.
. Do not spin your tires at high speed. This
could cause them to explode and result
in serious injury. Parts of your vehicle
could also overheat and be damaged.
Pulling a stuck vehicle
If your vehicle is stuck in sand, snow, mud,
etc., use a tow strap or other device
designed specifically for vehicle recovery.
Always follow the manufacturer’s instruc-
tions for the recovery device.
Remove the recovery hook cover from the
front bumper using a suitable tool.
Securely install the vehicle recovery hook
*1stored with jacking tools as illustrated.
Attach the tow strap to the recovery hook.
Make sure that the hook is properly
secured in the original place after use.
Do not use the tie down hook
*2for
towing or vehicle recovery.
CAUTION
. Tow chains or cables must be attached
only to the vehicle recovery hooks or
main structural members of the vehicle.
Otherwise, the vehicle body will be
damaged.
. Do not use the vehicle tie downs to free
a vehicle stuck in sand, snow, mud, etc.
. Never tow a vehicle using the vehicle tie
downs or recovery hooks.
. Always pull the cable straight out from
the front of the vehicle. Never pull on the
vehicle at an angle.
. Pulling devices should be routed so they
do not touch any part of the suspension,
steering, brake or cooling systems.
. Pulling devices such as ropes or canvas
straps are not recommended for use in
vehicle towing or recovery.
Rocking a stuck vehicle
If your vehicle is stuck in sand, snow, mud,
etc., use the following procedure:
1. Turn off the Vehicle Dynamic Control
(VDC) system. 2. Make sure the area in front and behind
the vehicle is clear of obstructions.
3. Turn the steering wheel right and left to clear an area around the front tires.
4. Slowly rock the vehicle forward and backward.
.Shift back and forth between R
(reverse) and D (drive).
.Apply the accelerator as little aspossible to maintain the rocking
motion.
.Release the accelerator pedal beforeshifting between R and D.
.Do not spin the tires above 35 MPH(55 km/h).
5. If the vehicle cannot be freed after a few tries, contact a professional towing
service to remove the vehicle.
