year around, including snowy and icy road con-
ditions. 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 tiresNISSAN specifies summer tires on some models
to provide superior performance on dry roads.
Summer tire performance in snow and ice will be
substantially reduced. Summer tires do not have
the tire traction rating M&S on the tire sidewall.
If you operate your vehicle in snowy or icy
conditions, NISSAN recommends the use of
SNOW or ALL SEASON tires on all four wheels.Snow tiresIf 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 on four wheel drivemodels, they must also be the same size, brand,
construction and tread pattern on all four
wheels.
If you operate your vehicle in snowy or icy
conditions, NISSAN recommends the use of
SNOW or ALL SEASON tire on all four wheels.
For additional traction on icy roads, studded tires
may be used. However, some provinces and
states 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 CHAINSUse of tire chains is 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 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 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 component required
to accommodate the use of a winter traction
device (tire chains or cables). The minimum
clearances are determined using the factoryequipped tire size. Other types may damage
your vehicle. 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 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 perfor-
mance may be adversely affected.
Never install tire chains on TEMPORARY USE
ONLY spare tires.
Do not use tire chains on dry roads.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Do not drive with tire chains on paved roads
which are clear of snow. Driving with chains in
such conditions can cause damage to the vari-
ous mechanisms of the vehicle due to some
overstress. When driving on clear paved roads,
be sure to change to 2WD.

SECURING THE LOADThere are tie down hooks located in the cargo
area. 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
lbs. (10 kg) to a single hook when securing
cargo.
LOADING TIPS
The GVW must not exceed GVWR or
GAWR as specified on the FMVSS Certifi-
cation Label located on the driver’s door
center pillar.

Do not load the front and rear axle to the
GAWR. Doing so will exceed the GVWR.

Loads 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 sliding or
shifting.
WARNING

Properly secure all cargo to help pre-
vent it from sliding or shifting. Do not
place cargo higher than the seat-
backs. In a sudden stop or collision,
unsecured cargo could cause per-
sonal injury.

Do not load your vehicle any heavier
than the GVWR or the maximum front
and rear GAWRs. If you do, parts on
your vehicle can break, or it can
change the way your vehicle handles.

This could result in loss of control
and cause personal injury.
PAYLOAD WEIGHT CAPACITYThe payload weight capacity is the maximum
total weight of passengers, 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 affixed to the glove box lid.

MEASUREMENT OF WEIGHTSSecure loose items to prevent weight shifts that
could affect the balance of your vehicle. When
the vehicle is loaded, drive to a scale and weight
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 certification label that is located on the
driver’s door lock pillar. If weight ratings are
exceeded, move or remove items to bring all
weights below the ratings.
CAUTION
Overloading can shorten the life of your
vehicle. Failures caused by overloading
are not covered by your warranty.Your new vehicle was designed to be used
primarily to carry passengers and cargo. Re-
member that towing a trailer will place additional
loads on your vehicle’s engine, drive train, steer-
ing, braking and other systems.
ANissan Trailer Towing Guide (US only)is
available from an authorized NISSAN dealer.
This guide includes information on trailer towing
ability and the special equipment required for
proper towing.

a tandem axle trailer whenever towing above 3,000 lb (1,361 kg).
*2: A sway control device is recommended for all towing above 2,000 lb (907 kg). Sway control devices
are not offered by NISSAN. See a professional trailer/hitch outlet for a properly designed sway control
device for your trailer.
TOWING SAFETY
Trailer hitchCheck the towing capacity of your 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
(US only). 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

Special hitches which include frame
reinforcements are required for tow-
ing above 2,000 lb (907 kg). Suitable
Genuine NISSAN hitches for pickup
truck and sport utility vehicles are
available at an authorized NISSAN
dealer.

Do not use axle-mounted hitches.

Do not modify the vehicle exhaust
system, brake system, etc. to install a
trailer hitch.Technical and consumer information
9-19


03.1.28/R50-D/V5


After the hitch is removed, seal the
bolt holes to prevent exhaust fumes,
water or dust from entering the pas-
senger compartment.

Regularly check all hitch mounting
bolts are securely mounted.

To reduce the possibility of addi-
tional damage if your vehicle is
struck from the rear, where practical,
remove the hitch and/or receiver
when not in use.

Never connect a trailer brake system
directly to the vehicle brake system.Tire pressures
When towing a trailer, inflate the vehicle tires
to the recommended cold tire pressure indi-
cated on the tire placard (affixed to the glove
box lid).

Trailer tire condition, size, load rating and
proper inflation pressure should be in accor-
dance with the trailer and tire manufacturers’
specifications.Safety chains
Always use a suitable chain between your ve-
hicle and the trailer. The chain 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 chain to permit turning
corners.Trailer lightsTrailer lights should comply with Federal and/or
local regulations.
When wiring vehicle for towing connection,
connect stop and tail light pickup into the
vehicle electrical circuit at point between
the sensor and stop light switch or light
switch.Trailer brakesIf your trailer is equipped with a braking system,
make sure it conforms to Federal and/or local
regulations and that it is properly installed.
WARNING
Never connect a trailer brake system
directly to the vehicle brake system.Trailer towing tipsIn order to gain skill and an understanding of thevehicle’s behavior, you should practice turning,
stopping and backing up in an area which is free
from traffic. Steering stability and braking perfor-
mance will be somewhat different than under
normal driving conditions.

Always secure items in the trailer to prevent
load shift while driving.

Avoid abrupt starts, acceleration or stops.

Avoid sharp turns or lane changes.

Always drive your vehicle at a moderate
speed.

Always block the wheels on both vehicle and
trailer when parking. Parking on a slope is not
recommended; however, if you must do so,
and if your vehicle is equipped with automatic
transmission, first block the wheels and apply
the parking brake, and then move the trans-
mission selector lever into the P position. If
you move the selector lever to the P position
before blocking the wheels and applying the
parking brake, transmission damage could
occur.

When going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending a long grade, downshift the
transmission to a lower gear and reduce
speed to reduce chances of engine overload-
ing and/or overheating.
