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.

WARNINGO Do not continue to drive if your ve-
hicle overheats. Doing so could
cause a vehicle fire.
O To avoid the danger of being scalded,
never remove the radiator cap while
the engine is still hot. When the radia-
tor cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
O 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 N (Neutral) position (automatic trans-
mission to the P (Park) position).
Do not stop the engine.
2. Turn off the air conditioner switch. Open all
the windows, move the heater or air condi- tioner 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. Wait until no
steam or coolant can be seen before pro-
ceeding.
5. Open the engine hood.
WARNING If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. Visually check if the cooling fan is running.
The radiator hoses and radiator should not
leak water.
If coolant is leaking or the cooling fan does
not run, stop the engine. WARNING O Be careful not to allow your hands,
hair, jewelry or clothing to come into
contact with, or to get caught in the
cooling fan, or drive belt.
O The engine cooling fan can start at
any time when the coolant tempera-
ture is high.
7. After the engine cools down, check the
coolant level in the reservoir tank with the
engine running. Add coolant to the reservoir
tank if necessary. Have your vehicle re-
paired at the nearest INFINITI retailer.
If needed, Roadside Assistance is available.

or Roadside Assistance I.D. Card for the toll-
free number to call (U.S.) or Warranty & Road-
side assistance information booklet (Canada).IF YOUR VEHICLE OVERHEATS

The engine cooling system is filled at the
factory with a high-quality, year-round, anti-
freeze coolant solution. The anti-freeze solu-
tion contains rust and corrosion inhibitors,
therefore additional cooling system additives
are not necessary.
CAUTIONWhen adding or replacing coolant, be
sure to use only a genuine NISSAN anti-
freeze coolant or equivalent with the
proper mixture ratio of 50% anti-freeze
and 50% demineralized water/distilled
water. The use of other types of coolant
solutions may damage your engine
cooling system. Outside temperature

CHECKING ENGINE COOLANT
LEVEL Check the coolant level in the reservoir tank
when the engine is cold. If the coolant level is
below MIN, add coolant up to the MAX level. If
the reservoir tank is empty, check the coolant
level in the radiator when the engine is cold.
If there is insufficient coolant in the radiator, fill
the radiator with coolant up to the filler opening
and also add it to the reservoir tank up to the
MAX level.
If the engine cooling system frequently
requires coolant, have it checked by your
INFINITI retailer. SDI1385

CHANGING ENGINE COOLANT O Major cooling system repairs should be
performed by your INFINITI retailer. The
service procedures can be found in the
appropriate INFINITI Service Manual. O Improper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING O To avoid being scalded, never change
the coolant when the engine is hot.
O Never remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator.
O Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
O Keep coolant out of reach of children
and pets.
1. Open radiator drain plug at the bottom of
radiator, and remove radiator filler cap.
O Be careful not to allow coolant to con-
tact drive belts.
O Waste coolant must be disposed of
properly. Check your local regulations.
2. Close the radiator drain plug securely after
the coolant is drained. 3. Fill the radiator slowly with the proper mix-
ture of anti-freeze solution and demineral-
ized water/distilled water. Fill the reservoir
tank up to the MAX level. Then install the
radiator filler cap.
4. Start the engine and warm it up until it
reaches normal operating temperature.
Then race the engine 2 or 3 times under no
load. Watch the engine coolant tempera-
ture gauge for signs of overheating.
5. Stop the engine. After it completely cools
down, refill the radiator up to the filler
opening. Fill the reservoir tank up to the
MAX level. Check the drain plug for any
sign of leakage.
6. Recheck the coolant level after the vehicle
has been driven for a day.SDI0114

EXPLANATION OF MAINTENANCE
ITEMS Additional information on the following
items with ª*º is found in the ª8. Do-it-
yourselfº section.
Emission control system
maintenance Drive belts*: Check drive belts for wear, fray-
ing or cracking and also for proper tension.
Replace the drive belts if found damaged.
Air cleaner filter: Under normal driving con-
ditions, the air cleaner filter should be replaced
in accordance with the maintenance schedule.
However, driving the vehicle in dusty areas
may cause more rapid clogging of the element.
Consequently, the element may have to be
replaced more frequently.
EVAP vapor lines: Check vapor lines and
connections for failure or looseness. If leaks
are found, replace them.
Fuel lines: Check the fuel hoses, piping and
connections for leaks, looseness or deteriora-
tion. Replace any parts if they are damaged.
Engine coolant*: Drain and flush the cooling
system.
Engine oil & oil filter*: Under normal driving conditions, the engine oil and oil filter should
be replaced in accordance with the mainte-
nance schedule. However, under severe driv-
ing conditions, they may have to be replaced
more frequently.
Spark plugs*: Replace with new plugs having
the correct heat range.
Chassis and body maintenance Brake lines & cables: Check the brake lines
and hoses (including brake booster vacuum
hoses, connections & check valve) and park-
ing brake cables for proper attachment, leaks,
cracks, chafing, abrasion, deterioration, etc.
Brake pads & rotors: Check these and the
other neighboring brake components for wear,
deterioration and leaks. Under severe driving
conditions, they may have to be inspected
more frequently.
Automatic transmission fluid*: Using auto-
matic transmission fluid other than Genuine
Nissan ATF Matic Fluid J will cause deteriora-
tion in driveability and automatic transmission
durability, and may damage the automatic
transmission, which is not covered by the
INFINITI new vehicle limited warranty. If
checking or replacement is required, we rec-
ommend your INFINITI retailer for servicing.
Under severe driving conditions, the fluid should be replaced at the specified interval.
Manual transmission oil & differential gear
oil*: Check the oil level and visually inspect for
signs of leakage.
Under severe driving conditions, the oil should
be replaced at the specified interval.
Steering gear & linkage, axle & suspension
parts: Check for damage, looseness and leak-
age of oil or grease. Under severe driving
conditions, more frequent inspection should be
performed.
Exhaust system: Visually check the exhaust
pipes, muffler, and hangers for proper attach-
ment, leaks, cracks, chafing, abrasion, dete-
rioration, etc. Under severe driving conditions,
inspection should be performed more fre-
quently.
In-cabin microfilter: Under normal condi-
tions, this microfilter should be replaced in
accordance with the maintenance schedule.
However, in some situations, the microfilter
may clog more rapidly (depending on the air
conditioner's working environment). If this hap-
pens, the air flow may decrease, or the win-
dows may fog up easily when the air condi-
tioner is in use, the microfilter should be
replaced immediately at your INFINITI retailer.
