WARNING
Be sure the engine and the ignition switch are
off and that the parking brake is engaged
securely.
CAUTION
Be sure to use the correct socket to remove the
spark plugs. An incorrect socket can damage
the spark plugs.
REPLACING SPARK PLUGS
If replacement is required, see an INFINITI re-
tailer for servicing.
Iridium-tipped spark plugs
It is not necessary to replace the iridium-tipped
spark plugs as frequently as the conventional
type spark plugs since they will last much
longer. Follow the maintenance schedule in
“INFINITI Service and Maintenance Guide”, but
do not reuse them by cleaning or regapping.
Always replace spark plugs with recommended
or equivalent ones.Remove the retainers
1as illustrated and pull
out the filter element
2.
The filter element should not be cleaned and
reused. Replace it according to the mainte-
nance intervals. See “INFINITI Service and Main-
tenance Guide” for maintenance intervals.

NOTE:
If the extended storage switch malfunctions, or
if the fuse is open, it is not necessary to replace
the switch. In this case, remove the extended
storage switch and replace it with a new fuse of
the same rating.
How to remove the extended storage switch:
1. To remove the extended storage switch,be sure the ignition switch is in the OFF or
LOCK position.
2. Be sure the headlight switch is in the OFF position.
3. Remove the fuse box cover.
4. Pinch the locking tabs
1found on each
side of the storage switch.
5. Pull the storage switch straight out from the fuse box
2.
Replace the battery as follows:1. Release the lock knob at the back of theIntelligent Key and remove the mechanical
key.
2. Insert a flat-blade screwdriver
A
wrapped with a cloth into the slitBof
the corner and twist it to separate the
upper part from the lower part. 3. Replace the battery with a new one.
Recommended battery: CR2032 or equivalent.
●
Do not touch the internal circuit and
electric terminals as it could cause a
malfunction.
● Hold the battery by the edges. Holding
the battery across the contact points will
seriously deplete the storage capacity.

Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rating to
the original equipment tires. If you do not, it can
adversely affect the safety and handling of your
vehicle.
Generally, snow tires will have lower speed
ratings than factory equipped tires and may not
match the potential maximum vehicle speed.
Never exceed the maximum speed rating of the
tire.
If you install snow tires, they must be the same
size, brand, construction and tread pattern on
all four wheels.
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 capa-
bilities of studded snow tires, on wet or dry
surfaces, may be poorer than that of non-
studded snow tires.
TIRE CHAINS
Use of tire chains may be prohibited according
to location. Check the local laws before install-
ing tire chains. When installing tire chains,
make sure they are the proper size for the tires
on your vehicle and are installed according to
the chain manufacturer’s suggestions.Use only
SAE Class S chains. Class “S” chains are used
on vehicles with restricted tire to vehicle clear-
ance. Vehicles that can use Class “S” chains are
designed to meet the SAE standard minimum
clearances between the tire and the closest
vehicle suspension or body component re-
quired to accommodate the use of a winter
traction device (tire chains or cables). The mini-
mum clearances are determined using the fac-
tory equipped tire size. Other types may dam-
age your vehicle. Use chain tensioners when
recommended by the tire chain manufacturer to
ensure a tight fit. Loose end links of the tire
chain must be secured or removed to prevent
the possibility of whipping action damage to
the fenders or underbody. If possible, 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 affected. Tire chains must be installed only on the rear
wheels and not on the front wheels.
Never install tire chains on a TEMPORARY USE
ONLY spare tire.
Do not use tire chains on dry roads. Driving with
tire chains in such conditions can cause dam-
age to the various mechanisms of the vehicle
due to some overstress.

3.Subtract the combined weight of the
driver and passengers from XXX kg or
XXX lbs.
4.The resulting figure equals the avail-
able amount of cargo and luggage
load capacity. For example, if the XXX
amount equals 1400 lbs. and there
will be five 150 lb. passengers in your
vehicle, the amount of available
cargo and luggage load capacity is
650 lbs. (1400750 (5 x 150) = 650
lbs or 640 340 (5 x 70) = 300 kg.)
5.Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo and
luggage load capacity calculated in
Step 4.
6.If your vehicle will be towing a trailer,
load from your trailer will be trans-
ferred to your vehicle. Consult this
manual to determine how this re-
duces the available cargo and lug-
gage load capacity of your vehicle. Before driving a loaded vehicle, confirm
that you do not exceed the Gross Vehicle
Weight Rating (GVWR) or the Gross Axle
Weight Rating (GAWR) for your vehicle.
(See “MEASUREMENT OF WEIGHTS” later
in this section.)
Also check tires for proper inflation pres-
sures. See the Tire and Loading Informa-
tion label.
LOADING TIPS
●The GVW must not exceed GVWR or
GAWR as specified on the
F.M.V.S.S./C.M.V.S.S. certification la-
bel.
●Do not load the front and rear axle to
the GAWR. Doing so will exceed the
GVWR.
WARNING
●Properly secure all cargo to help pre-
vent it from sliding or shifting. Do not
place cargo higher than the seatbacks.
In a sudden stop or collision, unsecured
cargo could cause personal injury.
●Do not load your vehicle any heavier
than the GVWR or the maximum front
and rear GAWRs. If you do, parts of your
vehicle can break, tire damage could oc-
cur, or it can change the way your ve-
hicle handles. This could result in loss
of control and cause personal injury.
●Overloading could not only shorten the
life of your vehicle and the tires, but
also could lead to hazardous vehicle
handling and long braking distance.
This may cause a premature tire mal-
function, which could result in a serious
accident and personal injury. Failures
caused by overloading are not covered
by the vehicle’s warranty.

MEASUREMENT OF WEIGHTS
Secure loose items to prevent weight
shifts that could affect the balance of
your vehicle. When the vehicle is loaded,
drive to a scale and weigh the front and
the rear wheels separately to determine
axle loads. Individual axle loads should
not exceed either of the gross axle
weight ratings (GAWR). The total of the
axle loads should not exceed the gross
vehicle weight rating (GVWR). These rat-
ings are given on the vehicle certifica-
tion label. If weight ratings are ex-
ceeded, move or remove items to bring
all weights below the ratings.
Your vehicle was designed to be used to carry
passengers and cargo. INFINITI does not recom-
mend trailer towing, because it places addi-
tional loads on your vehicle’s engine, drivetrain,
steering, braking, and other systems.
An INFINITI Towing Guide (U.S. only) is available
on the website at
www.InfinitiUSA.com. This guide includes infor-
mation on trailer towing capability and the
special equipment required for proper towing.
CAUTION
Vehicle damage resulting from towing a trailer
is not covered by INFINITI warranties.
FLAT TOWING
Towing your vehicle with all four wheels on the
ground is sometimes called flat towing. This
method is sometimes used when towing a
vehicle behind a recreational vehicle, such as a
motor home.
CAUTION
●Failure to follow these guidelines can result
in severe transmission damage.
● Whenever flat towing your vehicle, always
tow forward, never backward. ●
DO NOT tow any automatic transmission ve-
hicle with all four wheels on the ground (flat
towing). Doing so WILL DAMAGE internal
transmission parts due to lack of transmis-
sion lubrication.
● For emergency towing procedures refer to
“TOWING RECOMMENDED BY INFINITI” in the
“6. In case of emergency” section of this
manual.
Automatic transmission
To tow a vehicle equipped with an automatic
transmission, an appropriate vehicle dolly
MUST be placed under the towed vehicle’s drive
wheels. Alwaysfollow the dolly manufacturer’s
recommendations when using their product.
Manual transmission
● Always tow with the manual transmission in
Neutral.
● Your vehicle speed should never exceed 70
MPH (112 km/h) when flat towing your ve-
hicle.
● After towing 500 miles, start and idle the
engine with the transmission in Neutral for
two minutes. Failure to idle the engine after
every 500 miles of towing may cause dam-
age to the transmission’s internal parts.

Additional information concerning mo-
tor vehicle safety may be obtained from
Transport Canada’s Road Safety Infor-
mation Centre at 1-800-333-0371 or on-
line at www.tc.gc.ca/roadsafety
(English speakers) or
www.tc.gc.ca/securiteroutiere
(French speakers).
To notify INFINITI of any safety concerns
please contact our Consumer Informa-
tion Centre toll free at 1-800-361-4792.A vehicle equipped with All-Wheel Drive (AWD)
should never be tested using a two wheel
dynamometer (such as the dynamometers used
by some states for emissions testing), or similar
equipment. Make sure you inform test facility
personnel that your vehicle is equipped with
AWD before it is placed on a dynamometer.
Using the wrong test equipment may result in
transmission damage or unexpected vehicle
movement which could result in serious vehicle
damage or personal injury.
Due to legal requirements in some states/
areas, your vehicle may be required to be in
what is called the “ready condition” for an
Inspection/Maintenance (I/M) test of the emis-
sion control system.
The vehicle is set to the “ready condition” when
it is driven through certain driving patterns.
Usually, the “ready condition” can be obtained
by ordinary usage of the vehicle.
If a powertrain system component is repaired or
the battery is disconnected, the vehicle may be
reset to a “not ready condition”. Before taking
the I/M test, check the vehicle’s inspection/
maintenance test readiness condition. Place the
ignition switch in the ON position without start-
ing the engine. If the Malfunction Indicator Light
(MIL) comes on steady for 20 seconds and then
blinks for 10 seconds, the I/M test condition is“not ready”. If the MIL does not blink after 20
seconds, the I/M test condition is “ready”.
Contact a INFINITI retailer to set the “ready
condition” or to prepare the vehicle for testing.
