All-wheel drive models
CAUTION
Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), and tread pattern on all four
wheels. Failure to do so may result in a
circumference difference between tires
on the front and rear axles which will
cause excessive tire wear and may dam-
age the transmission, transfer case and
differential gears.
If excessive tire wear is found, it is recommended
that all four tires be replaced with tires of the
same size, brand, construction and tread pat-
tern. The tire pressure and wheel alignment
should also be checked and corrected as nec-
essary. Contact a NISSAN dealer.
Tire chains must be installed only on the
front wheels and not on the rear 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.
TIRE CHAINSUse 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 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 factory
equipped 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
undercarriage. If possible, avoid fully loading
your vehicle when using tire chains. In addition,
drive at a reduced speed. Otherwise, your ve-
hicle may be damaged and/or vehicle handling
and performance may be adversely affected.

Never install tire chains on a TEMPO-
RARY USE ONLY type spare tire.
Do not use the chains on dry roads.
Tire chains must be installed only on the
front wheels and not on the rear 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.

Steps for determining correct load
limit1. Locate the statement “The combined
weight of occupants and cargo should
never exceed XXX kg or XXX lbs” on
your vehicle’s placard.
2. Determine the combined weight of the
driver and passengers that will be
riding in your vehicle.
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.
(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 onthe vehicle. That weight may not safely
exceed the available cargo and lug-
gage 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 reduces
the available 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”
later in this section.
Also check tires for proper inflation pres-
sures. See the Tire and Loading Informa-
tion label.
LOADING TIPSThere 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.

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 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
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 con-
trol and cause personal injury.

Overloading not only can
shorten the life of your vehicle
and the tire, but can also cause
unsafe vehicle handling and
longer braking distances. Thismay cause a premature tire fail-
ure which could result in a seri-
ous accident and personal in-
jury. Failures caused by
overloading are not covered by
the vehicle’s warranty.
PAYLOAD WEIGHT CAPACITYThe payload weight capacity is the maxi-
mum total weight of passengers, optional
equipment (air conditioning, trailer hitch,
etc.) and cargo that your vehicle is de-
signed 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 informa-
tion” earlier in this section for details.
Also check tires for proper inflation pres-
sures. See the tire and loading informa-
tion label affixed to the driver’s door
center pillar.

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 ve-
hicle weight rating (GVWR). These rat-
ings are given on the vehicle certification
label. If weight ratings are exceeded,
move or remove items to bring all weights
below the ratings.

*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 hitchChoose a proper hitch for your vehicle and
trailer. 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.Hitch ballChoose a hitch ball of the proper size and weight
rating for your trailer:

The required hitch ball size is stamped on
most trailer couplers. Most hitch balls also
have the size printed on top of the ball.

Choose the proper class hitch ball based on
the trailer weight.

The diameter of the threaded shank of the
hitch ball must be matched to the ball mount
hole diameter. The hitch ball shank should be
no more than 1/16″smaller than the hole in
the ball mount.

The threaded shank of the hitch ball must be
long enough to be properly secured to the
ball mount. There should be at least 2 threads
showing beyond the lock washer and nut.Technical and consumer information

mount and hitch ball) can be used to tow trailers
of a maximum weight of 3,500 lb(1,510 kg).
CAUTION

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

Do not use axle-mounted hitches.

The hitch should not be attached to
or affect the operation of the impact-
absorbing bumper.

Do not modify the vehicle exhaust
system, brake system, etc. to install atrailer hitch.

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

Regularly check that all trailer 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.
Tire pressures
When towing a trailer, inflate the ve-
hicle tires to the recommended cold
tire pressure indicated on the Tire and
Loading Information label.

Trailer tire condition, size, load rating
and proper inflation pressure should
be in accordance with the trailer and
tire manufacturers’ specifications.
Safety chainAlways use a suitable chains between your
vehicle and the trailer. The 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 chain to permit turning
corners.Trailer lights
CAUTION
When splicing into the vehicle electrical
system, a commercially available
power-type module/converter must be
used to provide power for all trailer
lighting. This unit uses the vehicle bat-
tery as a direct power source for all
trailer lights while using the vehicle tail
light, stoplight and turn signal circuits
as a signal source. The module/
converter must draw no more than 15
milliamps from the stop and tail lamp
circuits. Using a module/converter that
exceeds these power requirements may
damage the vehicle’s electrical system.

the proper equipment and to have it
installed.
Trailer lights should comply with federal and/or
local regulations. For assistance in hooking up
trailer lights, contact a NISSAN dealer or repu-
table trailer dealer.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.Pre-towing tips
Be certain your vehicle maintains a level
position when a loaded and/or unloaded
trailer is hitched. Do not drive the vehicle if it
has an abnormal nose-up or nose-down con-
dition; check for improper tongue load, over-
load, worn suspension or other possible
causes of either condition.
Always secure items in the trailer to prevent
load shifts while driving.

Load the trailer so approximately 60% of the
trailer load is in the front half and 40% is in
the back half.

Check your hitch, trailer tire pressure, vehicle
tire pressure, trailer light operation, and trailer
wheel lug nuts every time you attach a trailer
to the vehicle.

Be certain your rearview mirrors conform to
all federal, state or local regulations. If not,
install any mirrors required for towing before
driving the vehicle.
Trailer towing tipsIn order to gain skill and an understanding of the
vehicle’s behavior, you should practice turning,
stopping and backing up in an area which is free
from traffic. Steering stability, and braking per-
formance 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. Some states or provinces have spe-cific speed limits for vehicles that are towing
trailers. Obey the local speed limits.

When backing up, hold the bottom of the
steering wheel with one hand. Move your
hand in the direction in which you want the
trailer to go. Make small corrections and back
up slowly. If possible, have someone guide
you when you are backing up.

Always block the wheels on both vehicle and
trailer when parking. Parking on a slope is not
recommended; however, if you must do so,
first block the wheels and apply the parking
brake, and then move the selector lever into
the P (Park) position. If you move the selector
lever to the P (Park) 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 going up a long grade, downshift the
transmission to a lower gear and reduce
speed to reduce chances of engine overload-
ing and/or overheating.

If the engine coolant rises to an extremely
high temperature when the air conditioning
system is on, turn off the air conditioner.
Coolant heat can be additionally vented by
opening the windows, switching the fan con-
trol to high and setting the temperature con-
