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.

Intelligent All-Wheel Drive (AWD)
models
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.
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
caution. Accelerate and slow down
with care. If accelerating or down-
shifting 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 pave-
ment.
. 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 steer-
ing 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 in
cold temperature starting.
The engine block heater should be used
when the outside temperature is 20°F
(−7°C) or lower.
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.
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.

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

1. Clean any mud or dirt from the surfacebetween the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight.
Models equipped with different sized
tires in the front and rear:
When replacing a front tire, make sure
that the hole in the spare tire wheel is
aligned with the pin on the brake rotor. 3. With the wheel nut wrench, tighten
wheel nuts alternately and evenly in the
sequence illustrated (
,,,,) until
they are tight.
4. Lower the vehicle slowly until the tire touches the ground. Then, with the
wheel nut wrench, tighten the wheel
nuts securely in the sequence as illu-
strated. Lower the vehicle completely.
WARNING
.Incorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.
. Do not use oil or grease on the wheel
studs or nuts. This could cause the
nuts to become loose.
. Retighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
.As soon as possible, tighten the wheel
nuts to the specified torque with a
torque wrench.
Wheel nut tightening torque: 80 ft-lb (108 N·m) The wheel nuts must be kept tigh-
tened to specification at all times. It
is recommended that wheel nuts be
tightened to specifications at each
lubrication interval.
.Adjust tire pressure to the COLD
pressure.
COLD pressure:
After the vehicle has been parked for
three hours or more or driven less
than 1 mile (1.6 km).

WARNING
. Always make sure that the spare tire
(if so equipped) and jacking equip-
ment are properly secured after use.
Such items can become dangerous
projectiles in an accident or sudden
stop. .
The T-type spare tire and small size
spare tire (if so equipped) are de-
signed for emergency use. See spe-
cific instructions under the heading
“Wheels and tires” (P.8-32). To start your engine with a booster battery,
the instructions and precautions below must
be followed.
WARNING
.
