FCC Notice:
For USA:
This device complies with Part 15 of the
FCC Rules. Operation is subject to the
following two conditions: (1) This device
may not cause harmful interference,
and (2) this device must accept any
interference received, including inter-

TIRE CHAINS
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
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 re-
stricted tire to vehicle clearance. 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 com-
ponent 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
vehicle. Use chain tensioners when re-
commended by the tire chain manufac-
turer 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 load-
ing your vehicle when using tire chains. In addition, drive at a reduced speed. Other-
wise, 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.
Do not use tire chains on dry roads.
Driving with tire chains in such conditions
can cause damage to the various me-
chanisms of the vehicle due to some
overstress.

9-2Maintenance and schedules
Some day-to-day and regular mainte-
nance is essential to maintain your vehi-
cle in good mechanical condition, as well
as its emission and engine performance.
It is the owner’s responsibility to make
sure that the scheduled maintenance, as
well as general maintenance, is per-
formed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives
the proper maintenance. You are a vital
link in the maintenance chain.
GENERAL MAINTENANCE
General maintenance includes those
items which should be checked during
normal day-to-day operation. They are
essential for proper vehicle operation. It is
your responsibility to perform these pro-
cedures regularly as prescribed.
Performing general maintenance checks
requires minimal mechanical skill and
only a few general automotive tools.
These checks or inspections can be done
by yourself, a qualified technician or, if you
prefer, a NISSAN dealer.
SCHEDULED MAINTENANCE
The maintenance items listed in this
section are required to be serviced at
regular intervals. However, under severe
driving conditions, additional or more
frequent maintenance will be required.
WHERE TO GO FOR SERVICE
If maintenance service is required or your
vehicle appears to malfunction, have the
systems checked and serviced. It is re-
commended you visit a NISSAN dealer for
this service.
NISSAN technicians are well-trained spe-
cialists and are kept up to date with the
latest service information through tech-
nical bulletins, service tips and training
programs. They are completely qualified
to work on NISSAN vehiclesbeforework
begins.
You can be confident that a NISSAN
dealer’s service department can perform
the service needed to meet the mainte-
nance requirements on your vehicle. During the normal day-to-day operation
of the vehicle, general maintenance
should be performed regularly as pre-
scribed in this section. If you detect any
unusual sounds, vibrations or smells, be
sure to check for the cause and have it
checked promptly. In addition, it is re-
commended you visit a NISSAN dealer if
you think that repairs are required.

from XXX kg or XXX lbs.
4. The resulting figure equals the available amount of cargo and
luggage load capacity. For ex-
ample, if the XXX amount equals
1400 lbs. and there will be five
150 lb. passengers in your vehi-
cle, the amount of available
cargo and luggage load capacity
is 650 lbs. (1400 − 750 (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 transferred to your vehicle.
Consult this manual to deter-
mine how this reduces the avail-
able cargo and luggage 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” (P.10-16).)
Also check tires for proper inflation
pressures. See the Tire and Loading
Information label.
SIC4446
SECURING THE LOAD
There are tie down hooks located in the
cargo area as shown. The tie down hooks
can be used to secure cargo with ropes or
other types of straps.
Do not apply a total load of more than
22 lb (10 kg) to a single hook
or 7 lb (3
kg) to a single hookwhen securing
cargo.
WARNING
. Properly secure all cargo with
ropes or straps to help prevent it
from sliding or shifting. Do not

place cargo higher than the seat-
backs. In a sudden stop or colli-
sion, unsecured cargo could
cause personal injury.
. The child restraint top tether
strap may be damaged by con-
tact with items in the cargo area.
Secure any items in the cargo
area. Your child could be seriously
injured or killed in a collision if the
top tether strap is damaged.
. 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
occur, or it can change the way
your vehicle handles. This could
result in loss of control and cause
personal injury.
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 prevent it from sliding
or shifting. Do not place
cargo higher than the seat-
backs. 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 occur, or it
can change the way your
vehicle handles. This could
result in loss of control and
cause personal injury.
. Overloading not only can
shorten the life of your ve-
hicle and the tire, but can
cause unsafe vehicle hand-
ling and long braking dis-
tance. This may cause a
premature tire failure, which
could result in a serious accident and personal in-
jury. 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 ratings
are given on the vehicle certifica-
tion label. If weight ratings are
exceeded, move or remove items
to bring all weights below the
ratings.
