FREEING A FROZEN DOOR LOCK To prevent a door lock from freezing, apply
de-icer or glycerin to it through the key hole. If
the lock becomes frozen, heat the key before
inserting it into the key hole.
ANTI-FREEZE In the winter when it is anticipated that the
temperature will drop below 32ÉF (0ÉC), check
anti-freeze to assure proper winter protection.
For additional information, see ªEngine Cool-
ing Systemº in the ª8. Do-it-yourselfº section.
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 ªBatteryº in the ª8. Do-it-
yourselfº section.
DRAINING OF COOLANT WATER If the vehicle is to be left outside without
anti-freeze, drain the cooling system by open-
ing the drain plug located under the radiator.
Refill before operating the vehicle. See ªEn-
gine cooling systemº in the ª8. Do-it-yourselfº
section for changing engine coolant. TIRE EQUIPMENT 1. SUMMER tires are of a tread design 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.
Please consult your INFINITI retailer for the
tire type, size, speed rating and availability
information.
2. For additional traction on icy roads, studded
tires may be used. However, some prov-
inces and states prohibit their use. Check
local, state and provincial laws before in-
stalling 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.
3. Tire chains may be used if desired. Make
sure they are of proper size for the tires on
your vehicle and are installed according to
the chain manufacturer's suggestions. Use
of tire chains may be prohibited according
to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are of proper size
for the tires on your vehicle and are in- stalled according to the chain manufactur-
er's suggestions. Use only SAE Class S
chains. Class ªSº chains are used on ve-
hicles with restricted tire to vehicle clear-
ance. Vehicles that can use Class ªSº
chains are designed to meet the SAE stan-
dard minimum clearances between the tire
and the closest vehicle suspension or body
component required to accommodate the
use of a winter traction device (tire chains
or cables). The minimum clearances are
determined using the factory equipped tire
size. Other types may damage your ve-
hicle. Use chain tensioners when recom-
mended by the tire chain manufacturer to
ensure a tight fit. Loose end links of the tire
chain must be secured or removed to pre-
vent the possibility of whipping action dam-
age to the fenders or underbody. If pos-
sible, avoid fully loading your vehicle when
using tire chains. In addition, drive at a
reduced speed. Otherwise, your vehicle
may be damaged and/or vehicle handling
and performance may be adversely af-
fected.
Never install tire chains on a T-type spare
tire. Do not use tire chains on dry roads.

When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to yourself
or damage to the vehicle. The following are
general precautions which should be closely
observed.
WARNINGO Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For a manual
transmission, move the shift lever to
N (Neutral) position. For an automatic
transmission, move the selector lever
to P (Park) position.
O Be sure the ignition key is OFF or
LOCK when performing any parts re-
placement or repairs.
O If you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving
fans, belts and any other moving
parts.
O It is advised to secure or remove any loose clothing and any jewelry, such
as rings, watches, etc. before work-
ing on your vehicle.
O Always wear eye protection when-
ever you work on your vehicle.
O If you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
O Never get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.
O Keep smoking materials, flame and
sparks away from fuel and the bat-
tery.
O On gasoline engine models with the
Multiport Fuel Injection (MFI) System,
the fuel filter or fuel lines should be
serviced by an INFINITI retailer be-
cause the fuel lines are under high
pressure even when the engine is off. CAUTION O Do not work under the hood while the
engine is hot. Turn off the engine and
wait until it cools down.
O Never connect or disconnect either
the battery or any transistorized com-
ponent connector while the ignition
key is on.
O Never leave any engine or automatic
transmission related component har-
ness connector disconnected while
the ignition key is on.
O Avoid direct contact with used engine
oil and coolant. Improperly disposed
engine oil, engine coolant and/or
other vehicle fluids can hurt the envi-
ronment. Always conform to local
regulations for disposal of vehicle
fluid.
This ª8. Do-it-yourselfº section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
