Generally, snow tires 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 operate your vehicle in snowy or icy
conditions, NISSAN recommends the use of
snow or all season tires 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 accord-
ing 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 sug-
gestions.Use only SAE Class ``S'' chains.
Other types may damage your vehicle. Use
chain tensioners when recommended by
the tire chain manufacturer to ensure a tightfit. Loose end links of the tire chain must be
secured or removed to prevent the possibil-
ity 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. Do not
exceed maximum speed suggested by the
chain manufacturer. Otherwise, your ve-
hicle may be damaged and/or vehicle han-
dling and performance 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
front wheels and not on the rear wheels.
CHANGING TIRES AND WHEELS
Tire rotation
Tires should be rotated every 7,500 miles
(12,000 km).
Tighten wheel nuts to 80 ft-lb (108 Nzm).

WARNING
cIt is extremely dangerous to ride in a
cargo area inside the vehicle. In a
collision, people riding in these ar-
eas are more likely to be seriously
injured or killed.
cDo not allow people to ride in any
area of your vehicle that is not
equipped with seats and seat belts.
c
Be sure everyone in the vehicle is in a
seat with their seat belt properly fas-
tened.
TERMS
It is important to familiarize yourself with the
following terms before loading your vehicle:
c
Curb Weight (actual weight of your ve-
hicle) - vehicle weight including: standard
and optional equipment, fluids, emergency
tools, and spare tire assembly. This weight
does notinclude passengers and cargo.
cGVW (Gross Vehicle Weight) - curb
weight plus the combined weight of pas-
sengers and cargo.
cGVWR (Gross Vehicle Weight Rating) -maximum total weight (load) limit speci-
fied for the vehicle.
cGAWR (Gross Axle Weight Rating) -
maximum weight (load) limit specified for
the front or rear axle.
cGross combined weight - GVW plus the
total weight of the trailer and all its cargo.
DETERMINING VEHICLE LOAD
CAPACITY
The load capacity of this vehicle is deter-
mined by weight, not by available cargo
space. For example, a luggage rack, bike
carrier, cartop carrier or similar equipment
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 de-
termine how much more weight your
vehicle can carry.3) After loading (cargo & passengers), re-
weigh your vehicle to determine if either
GVWR or GAWR for your vehicle is
exceeded. If GVWR is exceeded, re-
move cargo as necessary. If either the
front or rear GAWR is exceeded, shift
the load or remove cargo as necessary.
LOADING TIPS
cThe GVW must not exceed GVWR or
GAWR 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.
WARNING
c
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.

be properly distributed. For more informa-
tion regarding vehicle and trailer loading,
refer to The NISSAN Towing Guide, avail-
able from an authorized NISSAN dealer.
The ability of your vehicle to tow a trailer is
not only related to the maximum trailer
loads, but also the places you plan to tow.
Tow weights appropriate for level highway
driving may have to be reduced on very
steep grades or in low traction situations (for
example, on slippery boat ramps).
WARNING
Vehicle damage and/or personal injury
resulting from improper towing proce-
dures are not covered by NISSAN war-
ranties. A NISSAN Trailer Towing Guide
(U.S. only) containing information on
trailer towing ability and the special
equipment may be obtained from an
authorized NISSAN dealer.
Tongue load:
Keep the tongue load between 9 and 11%
of the total trailer load. If the tongue load
becomes excessive, rearrange cargo to al-
low for proper tongue load.
Maximum gross vehicle weight/
maximum gross axle weight
The gross vehicle weight of the towing
vehicle must not exceed the gross vehicle
weight rating (GVWR) shown on the
F.M.V.S.S. certification label. The gross ve-
hicle weight equals the combined weight of
the unloaded vehicle, passengers, luggage,
hitch, trailer tongue load and any other
optional equipment. In addition, front or rear
gross axle weight must not exceed the
gross axle weight rating (GAWR) shown on
the F.M.V.S.S. certification label.

TOWING SAFETY
Trailer hitch
Choose a proper hitch for your vehicle and
trailer. A genuine NISSAN trailer hitch is
available from your NISSAN dealer (USA
only). Make sure the trailer hitch is securely
attached to the vehicle to help avoid per-
sonal injury or property damage due to
sway caused by crosswinds, rough road
surfaces or passing trucks.
CAUTION
cDo not use axle-mounted hitches.
cThe hitch should not be attached to
or affect the operation of the impact-
absorbing bumper.
TI1012M
Technical and consumer information9-15
ZX

cDo not modify the vehicle exhaust
system, brake system, etc. to install
a trailer hitch.
cTo 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.
cAfter the hitch is removed, seal the
bolt holes to prevent exhaust fumes,
water or dust from entering the pas-
senger compartment.
cRegularly check that all hitch mount-
ing bolts are securely mounted.
Tire pressures
cWhen towing a trailer, inflate the vehicle
tires to the recommended cold tire pres-
sure indicated on the tire placard (located
on the inside of the glove box lid).
cTrailer tire condition, size, load rating and
proper inflation pressure should be in
accordance 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. When wiring the
vehicle for towing, connect the stop and tail
light pickup into the vehicle electrical circuit.
Class I Trailer Tow electrical wiring provides
two circuits (right and left hand) to operate
trailer stop/turn tail lamps. Each individual
stop/turn circuit will operate only one com-
bination stop/turn light bulb (#1157, 3157,
2357, or 3357) on the trailer. Never add
more than one trailer light bulb to one
circuit.

Trailer brakes
If your trailer is equipped with a braking
system, make sure it conforms to Federal
and/or local regulations and it is properly
installed.
WARNING
Never connect a trailer brake system
directly to the vehicle brake system.
Pre-towing tips
cBe 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 condition; check for improper
tongue load, overload, worn suspension
or other possible causes of either condi-
tion.
cAlways secure items in the trailer to
prevent load shift while driving.
cBe certain your rear view mirrors conform
to all federal, state or local regulations. If
not, install any mirrors required for towing
before driving the vehicle.
Trailer towing tips
In order to gain skill and an understanding
of the vehicle's behavior, you should prac-
tice turning, stopping and backing up in an
area which is free from traffic. Steering,
stability, and braking performance are
somewhat different than under normal driv-
ing conditions.
cAlways secure items in the trailer to
prevent load shift while driving.
c
Avoid abrupt starts, acceleration or stops.
cAvoid sharp turns or lane changes.
cAlways drive your vehicle at a moderate
speed.
cAlways 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 transmission shift selector le-
ver into the P (Park) position. If you move
the shift selector lever to the P (Park)
position before blocking the wheels and
applying the parking brake, transmission
damage could occur.
cWhen going down a hill, shift into a lowergear 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 en-
gine overloading and/or overheating.
cIf the engine coolant rises to an ex-
tremely high temperature when the air
conditioning system is on, turn the air
conditioner off. Coolant heat can be ad-
ditionally vented by opening the win-
dows, switching the fan control dial to
high and setting the temperature control
dial to the WARM position.
cTrailer towing requires more fuel than
normal circumstances.
cAvoid towing a trailer for the first 500
miles (800 km) of the vehicle's life.
cHave your vehicle serviced more often
than at intervals specified in the recom-
mended Maintenance Schedule in the
``NISSAN Service and Maintenance
Guide''.
cWhen making a turn, your trailer wheels
will be closer to the inside of the turn than
your vehicle wheels. To compensate for
this, make a larger than normal turning
radius during the turn.
