If the belt is in poor condition or loose, have
it replaced or adjusted by a NISSAN dealer.
2. Have the belts checked regularly for condi-
tion.
REPLACING SPARK PLUGSIf replacement is required, see a NISSAN dealer
for servicing.
WARNING
Be sure the engine and ignition switch
are off and that the parking brake is
engaged securely.
CAUTION
Be sure to use the correct socket to
remove the spark plugs. An incorrect
socket can damage the spark plugs.
Iridium-tipped spark plugsIt is not necessary to replace the iridium-tipped
spark plugs as frequently as the conventional
type spark plugs since they will last much longer.
Follow the maintenance log shown in the
“NISSAN Service and Maintenance Guide”, but
do not service iridium-tipped spark plugs by
cleaning or regapping.
Always replace spark plugs with recom-
mended or equivalent ones.

TIRE CHAINS
CAUTION
Tire chains/cables should not be in-
stalled on 265/35R19 size tires. Installa-
tion of the tire chains/cables on
265/35R19 size tires will cause damage
to the vehicle. If you plan to use tire
chains/cables, you should install
245/45R18 size tires on your vehicle.
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 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 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 the tire chains on a T-type
spare tire.

Do not use the tire chains on dry roads.

Tire chains must be installed only on the
rear wheels and not on the front wheels.
CHANGING WHEELS AND TIRES
Tire rotationTires cannot be rotated in this vehicle, as
front tires are different size from rear tires
and the direction of wheel rotation is fixed
in each tire.
A pin is on the front brake rotor to prevent
the rear wheels from being installed in
place of the front wheels. The spare tire
can be installed in place of the front and
rear wheels. When installing the spare
tire in the front wheel, the hole in the
spare tire wheel must be aligned with the
pin on the brake rotor.

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 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 with
ropes or straps to help prevent
it from sliding or shifting. Donot 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 could
shorten the life of your vehicle
and the tire, but can also cause
unsafe vehicle handling and
long braking distances. This
may cause a premature tire fail-
ure, which could result in a se-
rious accident and personal in-
jury. Failures caused by over
loading are not covered by thevehicle’s warranty.
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 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.

Tongue loadKeep the tongue load between 9 and 11% of the
total trailer load within the maximum tongue load
limits shown in the following Towing
Load/Specification chart. If the tongue load be-
comes excessive, rearrange cargo to allow for
proper tongue load.
Maximum gross vehicle weight/
maximum gross axle weightThe gross vehicle weight of the towing vehicle
must not exceed. GVWR shown on the
F.M.V.S.S./C.M.V.S.S. certification label. The
gross vehicle 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 GAWR
shown on the F.M.V.S.S./C.M.V.S.S. certifica-
tion label.

TOWING SAFETY
Trailer hitchChoose a proper hitch for a 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 cross-
winds, 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
TI1011M
TI1012M
9-18
Technical and consumer information


07.2.9/Z33-D/V5.0


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.
Class I hitchClass I trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow trailers
of a maximum weight of 2,000 lb(909 kg).
You may add Class I trailer hitch equipment to
the vehicle that has a 2,000 lb(909 kg) maxi-
mum weight rating, but your vehicle is only
capable of towing the maximum trailer weights
shown in the Towing Load/Specification Chart
earlier in this section.
CAUTION

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.

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

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.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 chainsAlways use a suitable chain between a vehicle
and the trailer. The safety 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 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. When wiring the vehicle for
towing, connect the stop and tail light pickup
into the vehicle electrical circuit at a point be-
tween the sensor and stop light 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.Pre-towing tips
Be certain a vehicle maintains a level position
when a loaded and/or unloaded trailer is
hitched. Do not drive the vehicle if it has an
unusual nose-up or nose-down condition;
check for improper tongue load, overload,
worn suspension or other possible causes of
these conditions.
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 rear view mirrors conform to
all federal, state and/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 a vehicle at a moderate speed.
Some states or provinces have specificspeed 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,
and if a vehicle is equipped with automatic
transmission, first apply the parking brake
and block the wheels, and then move the
transmission 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, the transmis-
sion may get damaged.

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
