∙ Pre-mix washer fluid concentrateswith water to the manufacturer’s rec-
ommended levels before pouring the
fluid into the windshield-washer fluid
reservoir. Do not use the windshield-
washer fluid reservoir to mix the
washer fluid concentrate and water. ∙ Keep the battery surface clean and dry.
Clean the battery with a solution of bak-
ing soda and water.
∙ Make certain the terminal connections are clean and securely tightened.
∙ If the vehicle is not to be used for 30 days or longer, disconnect the nega-
tive (-) battery terminal cable to prevent
discharge.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as: 1. Installation or extended use of elec-
tronic accessories that consume bat-
tery power when the engine is not
running (Phone chargers, GPS, DVD
players, etc).
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health.WARNING
∙ Do not expose the battery to flames, an electrical spark or a cigarette. Hy-
drogen gas generated by the battery
is explosive. Explosive gases can
cause blindness or injury. Do not allow
battery fluid to contact your skin,
eyes, fabrics or painted surfaces. Sul-
furic acid can cause blindness or in-
jury. Af ter touching a battery or bat-
tery cap, do not touch or rub your
eyes. Thoroughly wash your hands. If
the acid contacts your eyes, skin or
clothing, immediately flush with wa-
ter for at least 15 minutes and seek
medical attention.
∙ Do not operate the vehicle if the fluid in the battery is low. Low battery fluid
can cause a higher load on the battery
which can generate heat, reduce bat-
tery life, and in some cases lead to an
explosion.
∙ When working on or near a battery, always wear suitable eye protection
and remove all jewelry.

Steps for determining correct
load limit
1. Locate the statement “The com-bined weight of occupants and
cargo should never exceed XXX
lbs. or XXX kg” on your vehicle’s
Tire and Loading Information la-
bel.
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 lbs. or XXX kg.
4. The resulting figure equals the available amount of cargo and
luggage load capacity. For ex-
ample, if the XXX amount equals
1,400 lbs. and there will be five
150 lbs. passengers in your ve-
hicle, the amount of available
cargo and luggage load capac-
ity is 650 lbs. (1,400-750 (5 X 150) =
650 lbs.) or (640-340 (5 X 70) =
300 kg.) 5. Determine the combined weight
of luggage and cargo being
loaded on the vehicle. That
weight may not safely exceed
the available cargo and luggage
load capacity calculated in
step 4.
Before driving a loaded vehicle, con-
firm that you do not exceed the
Gross Vehicle Weight Rating (GVWR)
or the Gross Axle Weight Rating
(GAWR) for your vehicle. For addi-
tional information, refer to “Measure-
ment of weights” in this section.
Also check tires for proper inflation
pressures. For additional informa-
tion, refer to “Tire and Loading Infor-
mation label” in this section.
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 shif ting. 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 control
and cause personal injury.
Technical and consumer information10-15

∙ Overloading not only canshorten the life of your vehicle
and the tire, but can also cause
unsafe vehicle handling and
longer braking distances. This
may 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.
MEASUREMENT OF WEIGHTS
Secure loose items to prevent
weight shif ts that could affect the
balance of your vehicle. When the ve-
hicle 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
Ratings (GAWR). The total of the axle
loads should not exceed the Gross
Vehicle Weight Rating (GVWR). These
ratings are given on the vehicle cer-
tification label. If weight ratings are
exceeded, move or remove items to
bring all weights below the ratings.
Do not tow a trailer with your vehicle.
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 ve-
hicle, 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.
∙ Never tow your front wheel drive ve- hicle with the front tires on the
ground. Doing so may cause serious
and expensive damage to the
powertrain.
∙ DO NOT tow any continuously variable transmission vehicle with all four
wheels on the ground (flat towing).
Doing so WILL DAMAGE internal trans-
mission parts due to lack of transmis-
sion lubrication. ∙ For emergency towing procedures re-
fer 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 continu-
ously variable transmission, an appropriate
vehicle dolly MUSTbe placed under the
towed vehicle’s drive wheels. Alwaysfollow
the dolly manufacturer’s recommenda-
tions when using their product.
