cFor additional information regarding
tires, refer to Important Tire Safety In-
formation (US) or Tire Safety Informa-
tion (Canada) in the Warranty Informa-
tion Booklet.
All season tires
NISSAN specifies All Season tires on some mod-
els to provide good performance all year, includ-
ing snowy and icy road conditions. All Season
tires are identified by ALL SEASON and/or M&S
on the tire sidewall. Snow tires have better snow
traction than All Season tires and may be more
appropriate in some areas.
Summer tires
NISSAN specifies summer tires on some models
to provide superior performance on dry roads.
Summer tire performance is substantially re-
duced in snow and ice. Summer tires do not have
the tire traction rating “M&S” on the tire sidewall.
If you plan to operate your vehicle in snowy or icy
conditions, NISSAN recommends the use of
SNOW tires or ALL SEASON tires on all four
wheels.
Snow tires
If snow tires are needed, it is necessary to select
tires equivalent in size and load rating to theoriginal equipment tires. If you do not, it can
adversely affect the safety and handling of your
vehicle.
Generally, snow tires have lower speed ratings
than factory equipped tires and may not match
the potential maximum vehicle speed. Never ex-
ceed 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 capabilities 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 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.Class9S9chains are used on
vehicles with restricted tire to vehicle clearance.
Vehicles that can use Class “S” chains are de-
signed to meet the minimum clearances betweenthe 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 vehicle. Use chain tensioners
when recommended 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 addi-
tion, 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
chains in such conditions can cause damage to
the various mechanisms of the vehicle due to
some overstress.
Use only the 2WD range when driving on clear
paved roads.

cGAWR (Gross Axle Weight Rating) - maxi-
mum weight (load) limit specified for the
front or rear axle.
DETERMINING VEHICLE LOAD
CAPACITY
The load capacity of this vehicle is determined by
weight, not by available cargo space. For ex-
ample, a roof rack, bike carrier, or similar equip-
ment does not increase load carrying capacity of
your vehicle.
To determine vehicle load capacity:
Vehicle weight can be determined by using a
commercial-grade scale, found at places such as
a truck stop, gravel quarry, grain elevator, or a
scrap metal recycling facility.
1. Determine the curb weight of your vehicle.
2. Compare the curb weight amount to the
GVWR specified for your vehicle to deter-
mine how much more weight your vehicle
can carry.
3. After loading (cargo and passengers) , re-
weigh your vehicle to determine if either
GVWR or GAWR for your vehicle is ex-
ceeded. If GVWR is exceeded, remove
cargo as necessary. If either the front or rear
GAWR is exceeded, shift the load or remove
cargo as necessary.
1. Plastic hook
2. Metal hook
SECURING THE LOAD
There are tie down hooks located in both the
ceiling and floor of 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 33
lbs. (15 kg) to a single plastic ceiling or
metal floor tie-down hook when securing
cargo.Do not apply a total load of more than
110lbs. (50 kg) to a single metal ceiling
tie-down hook when securing cargo.

WARNING
cProperly secure all cargo with ropes or
straps to help prevent it from sliding or
shifting. Do not place cargo higher than
the seatbacks. In a sudden stop or col-
lision, unsecured cargo could cause
personal injury.cDo 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
cThe GVW must not exceed GVWR or
GAWR as specified on the F.M.V.S.S. Cer-
tification Label.
cDo not load the front and rear axle to the
GAWR. Doing so will exceed the GVWR.
cLoads should be spread out, and cargo
should be properly secured. Large or heavy
objects should be placed toward the front of
the cargo area to help prevent shifting.
CAUTION
Overloading can shorten the life of the
vehicle. Failures caused by overloading
are not covered by the vehicle’s warranty.
PAYLOAD WEIGHT CAPACITY
The payload weight capacity shown on following
charts indicate the maximum total weight of pas-
sengers, optional equipment (air conditioning,
trailer hitch, etc) and cargo that your vehicle is
designed to carry.
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 ’’Vehicle Loading
Information’’ earlier in this section for details.
Also check tires for proper inflation pressures.
See the tire placard .

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 deter-
mine 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 rat-
ings.

TOWING SAFETY
Trailer hitch
Check the towing capacity of your bumper hitch
or receiver-type frame mounted hitch. Choose a
proper hitch for your vehicle and trailer. A genuine
Nissan trailer hitch is available from your NISSAN
dealer. Make sure the trailer hitch is securely
attached to the vehicle to help avoid personal
injury or property damage due to sway caused by
crosswinds, rough road surfaces or passing
trucks.
CAUTION
cSpecial hitches which include frame re-
inforcements are required for towing
above 2,000 lb (907 kg) . Suitable genu-
ine NISSAN hitches for pickup trucks
and sport utility vehicles are available
at a NISSAN dealer.
cThe hitch should not be attached to or
affect the operation of the impact-
absorbing bumper.
cDo not use axle-mounted hitches.
cDo not modify the vehicle exhaust sys-
tem, brake system, etc. to install a
trailer hitch.cTo reduce the possibility of additional
damage if your vehicle is struck from
the rear, where practical, remove the
hitch and/or receiver when not in use.
cAfter the hitch is removed, seal the bolt
holes to prevent exhaust fumes, water
or dust from entering the passenger
compartment.
cRegularly check that all trailer hitch
mounting bolts are securely mounted.
Tire pressures
cWhen towing a trailer, inflate the vehicle tires
to the recommended cold tire pressure indi-
cated on the tire placard.
cTrailer tire condition, size, load rating and
proper inflation pressure should be in accor-
dance with the trailer and tire manufacturer’s
specifications.
Safety chains
Always use suitable safety chains between your
vehicle and the trailer. Safety chains should be
crossed and should be attached to the hitch, not
to the vehicle bumper or axle. Be sure to leave
enough slack in the chains to permit turning
corners.
Trailer lights
Trailer lights should comply with federal and/or
local regulations. For assistance in hooking up
trailer lights, contact a NISSAN dealer.
