●Do not modify the vehicle’s suspension. If
suspension parts such as shock absorbers,
struts, springs, stabilizer bars, bushings
and wheels are not INFINITI recommended
for your vehicle or are extremely deterio-
rated, the VDC system may not operate prop-
erly. This could adversely affect vehicle han-
dling performance, and the VDC warning
light
may illuminate.
● If brake related parts such as brake pads,
rotors and calipers are not INFINITI recom-
mended or are extremely deteriorated, the
VDC system may not operate properly and
the VDC warning light
may illuminate.
● If engine control related parts are not
INFINITI recommended or are extremely de-
teriorated, the VDC warning light
may
illuminate.
● When driving on extremely inclined surfaces
such as higher banked corners, the VDC sys-
tem may not operate properly and the VDC
warning light
may illuminate. Do not
drive on these types of roads.
● When driving on an unstable surface such as
a turntable, ferry, elevator or ramp, the VDC
warning light
may illuminate. This is
not a malfunction. Restart the engine after
driving onto a stable surface. ●
If wheels or tires other than the INFINITI rec-
ommended ones are used, the VDC system
may not operate properly and the VDC warn-
ing light
may illuminate.
● The VDC system is not a substitute for winter
tires or tire chains on a snow covered road.
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 32°F (0°C),
check antifreeze to assure proper winter protec-
tion. For additional information, see “ENGINE
COOLING SYSTEM” in the “8. Maintenance and
do-it-yourself” 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 “BATTERY” in the “8. Mainte-
nance and do-it-yourself” section.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For details, see “ENGINE COOLING SYS-
TEM” in the “8. Maintenance and do-it-yourself”
section.

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 gen-
eral precautions which should be closely ob-
served.
WARNING
●Park the vehicle on a level surface, apply the
parking brake securely and block the wheels
to prevent the vehicle from moving. Move
the selector lever to P (Park).
● Be sure the ignition switch is in the OFF or
LOCK position when performing any parts
replacement or repairs.
● Never connect or disconnect the battery or
any transistorized component while the ig-
nition switch is in the ON position.
● Never leave the engine or automatic trans-
mission related component harnesses dis-
connected while the ignition switch is in the
ON position.
● 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. ●
It is advisable to secure or remove any loose
clothing and remove any jewelry, such as
rings, watches, etc. before working on your
vehicle.
● Always wear eye protection whenever you
work on your vehicle.
● 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.
● Never get under the vehicle while it is sup-
ported only by a jack. If it is necessary to
work under the vehicle, support it with
safety stands.
● Keep smoking materials, flame and sparks
away from fuel tank and the battery.
● Your vehicle is equipped with an automatic
engine cooling fan. It may come on at any
time without warning, even if the ignition
key is in the OFF position and the engine is
not running. To avoid injury, always discon-
nect the negative battery cable before work-
ing near the fan.
● On gasoline engine models, the fuel filter or
fuel lines should be serviced by an INFINITI
retailer because the fuel lines are under high
pressure even when the engine is off.
CAUTION
● Do not work under the hood while the engine
is hot. Turn the engine off and wait until it
cools down.
● Avoid direct contact with used engine oil and
coolant. Improperly disposed engine oil,
coolant, and/or other vehicle fluids can dam-
age the environment. Always conform to lo-
cal regulations for disposal of vehicle fluid.
This “8. Maintenance and do-it-yourself” sec-
tion gives instructions regarding only those
items which are relatively easy for an owner to
perform.
A genuine INFINITI Service Manual is also avail-
able. (See “OWNER’S MANUAL/SERVICE
MANUAL ORDER INFORMATION” in the “9. Tech-
nical and consumer information” section.)
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could affect
your warranty coverage. If in doubt about any
servicing, we recommend that it be done by an
INFINITI retailer.
