5. Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo and
luggage 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 re-
duces the available cargo and lug-
gage 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 TIPS
●The GVW must not exceed GVWR
or GAWR as specified on the
F.M.V.S.S./C.M.V.S.S. certification
label.
●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 seat-
backs. In a sudden stop or colli-
sion, 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 oc-
cur, or it can change the way your
vehicle handles. This could result
in loss of control and cause per-
sonal injury.●Overloading not only can shorten
the life of your vehicle and the
tire, but can also cause unsafe
vehicle handling and longer brak-
ing distances. This may cause a
premature tire failure which
could result in a serious accident
and personal injury. Failures
caused by overloading are not
covered by the vehicle’s
warranty.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 determine axle
loads. Individual axle loads should not ex-
ceed either of the gross axle weight rat-
ings (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. If
weight ratings are exceeded, move or re-
move items to bring all weights below the
ratings.

WARNING
Never connect a trailer brake system di-
rectly to the vehicle brake system.
When towing a trailer load of 3,500 lbs.
(1587 kg) or more, trailers with a brake
system MUST be used. However, most
states require a separate braking system
on trailers with a loaded weight above a
specific amount. Make sure the trailer
meets the local regulations and the regu-
lations where you plan to tow.
Several types of braking systems are
available.
Surge Brakes - The surge brake actuator
is mounted on the trailer tongue with a
hydraulic line running to each trailer
wheel. Surge brakes are activated by the
trailer pushing against the hitch ball when
the tow vehicle is braking. Hydraulic surge
brakes are common on rental trailers and
some boat trailers. In this type of system,
there is no hydraulic or electric connec-
tion for brake operation between the tow
vehicle and the trailer.Electric Trailer Brakes - Electric braking
systems are activated by an electronic sig-
nal sent from a trailer brake controller
(special brake-sensing module) . If electric
trailer brakes are used, seeElectric trailer
brake controllerin this section.
Have a professional supplier of towing
equipment make sure the trailer brakes
are properly installed and demonstrate
proper brake function testing.
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
condition; check for improper tongue load,
overload, worn suspension or other possible
causes of either condition.
●Always secure items in the trailer to prevent
load shift while driving.
●Keep the cargo load as low as possible in
the trailer to keep the trailer center of gravity
low.
●Load the trailer so approximately 60% of the
trailer load is in the front half and 40% is in
the back half. Also make sure the load is
balanced side to side.●Check your hitch, trailer tire pressure, ve-
hicle 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.
●Determine the overall height of the vehicle
and trailer so the required clearance is
known.Trailer towing tips
In 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 perfor-
mance will be somewhat different than under
normal driving conditions.
●Always secure items in the trailer to prevent
load shift while driving.
●Lock the trailer hitch coupler with a pin or
lock to prevent the coupler from inadvert-
ently becoming unlatched.
●Avoid abrupt starts, acceleration or stops.
●Avoid sharp turns or lane changes.

●Always drive your vehicle at a moderate
speed.
●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:
CAUTION
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.
1. Apply and hold the brake pedal.
2. Have someone place blocks on the downhill
side of the vehicle and trailer wheels.
3. After the wheel blocks are in place, slowly
release the brake pedal until the blocks ab-
sorb the vehicle load.
4. Apply the parking brake.
5. Shift the transmission into P (Park) .
6. Turn off the engine.To drive away:
1. Start the vehicle.
2. Apply and hold the brake pedal.
3. Shift the transmission into gear.
4. Release the parking brake.
5. Drive slowly until the vehicle and trailer are
clear from the blocks.
6. Apply and hold the brake pedal.
7. Have someone retrieve and store the blocks.
●While going downhill, the weight of the
trailer pushing on the tow vehicle may de-
crease overall stability. Therefore, to main-
tain adequate control, reduce your speed
and shift to a lower gear. Avoid long or
repeated use of the brakes when descend-
ing a hill, as this reduces their effectiveness
and could cause overheating. Shifting to a
lower gear instead provides “engine brak-
ing” and reduces the need to brake as fre-
quently.
●If the engine coolant temperature rises to a
high temperature, refer to “If your vehicle
overheats” in the “In case of emergency”
section of this owner’s manual.
●Trailer towing requires more fuel than normal
circumstances.●Avoid towing a trailer for your vehicle’s first
500 miles (805 km) .
●For the first 500 miles (805 km) that you do
tow, do not drive over 50 MPH (80 km/h) .
●Have your vehicle serviced more often than
at intervals specified in the recommended
Maintenance Schedule in the “NISSAN Ser-
vice and Maintenance Guide”.
●When 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.
●Crosswinds and rough roads will adversely
affect vehicle/trailer handling, possibly caus-
ing vehicle sway. When being passed by
larger vehicles, be prepared for possible
changes in crosswinds that could affect ve-
hicle handling.
Do the following if the trailer begins to sway:
1. Take your foot off the accelerator pedal to
allow the vehicle to coast and steer as
straight ahead as the road conditions allow.
This combination will help stabilize the ve-
hicle.
– Do not correct trailer sway by steering or
applying the brakes.

2. When the trailer sway stops, gently apply the
brakes and pull to the side of the road in a
safe area.
3. Try to rearrange the trailer load so it is bal-
anced as described earlier in this section.
●Be careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal pass-
ing. Remember, the length of the trailer must
also pass the other vehicle before you can
safely change lanes.
●Use the Tow Mode or downshift the trans-
mission to a lower gear for engine braking
when driving down steep or long hills. This
will help slow the vehicle without applying
the brakes.
●Avoid holding the brake pedal down too long
or too frequently. This could cause the
brakes to overheat, resulting in reduced
braking efficiency.
●Increase your following distance to allow for
greater stopping distances while towing a
trailer. Anticipate stops and brake gradually.
●NISSAN recommends that the cruise con-
trol not be used while towing a trailer.●Some states or provinces have specific
regulations and speed limits for vehicles that
are towing trailers. Obey the local speed
limits.
●Check your hitch, trailer wiring harness con-
nections, and trailer wheel lug nuts after 50
miles (80 km) of travel and at every break.
●When launching a boat, don’t allow the wa-
ter level to go over the exhaust tail pipe or
rear bumper.
●Make sure you disconnect the trailer lights
before backing the trailer into the water or
the trailer lights may burn out.
When towing a trailer, transmission fluid
should be changed more frequently. For
additional information, see the “Mainte-
nance and do-it-yourself” section earlier in
this manual.
FLAT TOWING
Towing your vehicle with all four wheels on the
ground is sometimes called flat towing. This
method is sometimes used when towing a vehicle
behind a recreational vehicle, such as a motor
home.
CAUTION
●Failure to follow these guidelines can
result in severe transmission damage.
●Whenever flat towing your vehicle, al-
ways tow forward, never backward.
●DO NOT tow any continuously variable
transmission vehicle with all four
wheels on the ground (flat towing) . Do-
ing so WILL DAMAGE internal transmis-
sion parts due to lack of transmission
lubrication.
●For emergency towing procedures refer
to “Towing recommended by NISSAN”
in the “In case of emergency” section of
this manual.
Continuously Variable Transmission
To tow a vehicle equipped with a continuously
variable transmission, an appropriate vehicle dolly
MUST
be placed under the towed vehicle’s drive
wheels.Alwaysfollow the dolly manufacturer’s
recommendations when using their product.

Manual Transmission
●Always tow with the manual transmission in
Neutral.
●After towing 500 miles (805 km) , start and
idle the engine with the transmission in Neu-
tral for two minutes. Failure to idle the engine
after every 500 miles (805 km) of towing
may cause damage to internal transmission
parts.DOT (Department of Transportation) Quality
Grades: All passenger car tires must conform to
federal safety requirements in addition to these
grades.
Quality grades can be found where applicable on
the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA Temperature A
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course. For example, a tire graded
150 would wear one and one-half (1 1/2) times
as well on the government course as a tire graded
100. The relative performance of tires depends
upon the actual conditions of their use, however,
and may depart significantly from the norm due to
variations in driving habits, service practices and
differences in road characteristics and climate.
Traction AA, A, B and C
The traction grades, from highest to lowest, are
AA, A, B, and C. Those grades represent the
tire’s ability to stop on wet pavement as mea-
sured under controlled conditions on specified
government test surfaces of asphalt and con-
crete. A tire marked C may have poor traction
performance.
WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
Temperature A, B and C
The temperature grades are A (the highest) , B,
and C, representing the tire’s resistance to the
generation of heat, and its ability to dissipate heat
when tested under controlled conditions on a
specified indoor laboratory test wheel. Sustained
high temperature can cause the material of the
tire to degenerate and reduce tire life, and exces-
sive temperature can lead to sudden tire failure.
The grade C corresponds to a level of perfor-
mance which all passenger car tires must meet
under the Federal Motor Safety Standard No.
109. Grades B and A represent higher levels of
performance on the laboratory test wheel than
the minimum required by law.
