fuel additives (i.e.: fuel injector cleaner, octane
booster, intake valve deposit removers, etc.)
which are sold commercially. Many of these
additives intended for gum, varnish or deposit
removal may contain active solvents or similar
ingredients that can be harmful to the fuel
system and engine.Octane rating tipsIn most parts of North America, you should use
unleaded gasoline with an octane rating of at
least 91 AKI (Anti-Knock Index) number
(VQ35DE engine) or 87 AKI (Anti-knock Index)
number (VG33E engine). However, you may
use unleaded gasoline with an octane rating
as low as 85 AKI (Anti-Knock Index) number in
these high altitude areas [over 4,000 ft (1,219
m)] such as: Colorado, Montana, New Mexico,
Utah, Wyoming, northeastern Nevada, south-
ern Idaho, western South Dakota, western
Nebraska, and that part of Texas which is
directly south of New Mexico.
Using unleaded gasoline with an octane
rating lower than stated above can cause
persistent, heavy spark knock. (Spark
knock is a metallic rapping noise.) If se-
vere, this can lead to engine damage. If you
detect a persistent heavy spark knock even
when using gasoline of the stated octane
rating, or if you hear steady spark knockwhile holding a steady speed on level
roads, have your dealer correct the condi-
tion. Failure to correct the condition is
misuse of the vehicle, for which NISSAN is
not responsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may
cause excessive fuel consumption or damage
to the engine. If any of the above symptoms
are encountered, have your vehicle checked at
a NISSAN dealer or other competent service
facility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is no
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time.

This could result in loss of control
and cause personal injury.
PAYLOAD WEIGHT CAPACITYThe payload weight capacity is the maximum
total weight of passengers, optional equipment
(air conditioning, trailer hitch, etc.) and cargo
that your vehicle is designed 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 ªVehicle
loading informationº earlier in this section for
details.
Also check tires for proper inflation pressures.
See the tire placard affixed to the glove box lid.

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 weight 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
vehicle weight rating (GVWR). These ratings
are given on the vehicle certification label that
is located on the driver's door lock pillar. If
weight ratings are exceeded, move or remove
items to bring all weights below the ratings.
CAUTION
Overloading can shorten the life of your
vehicle. Failures caused by overloading
are not covered by your warranty.Your new vehicle was designed to be used
primarily to carry passengers and cargo. Re-
member that towing a trailer will place addi-
tional loads on your vehicle's engine, drive
train, steering, braking and other systems.
ANissan Trailer Towing Guide (US only)is
available from an authorized NISSAN dealer.
This guide includes information on trailer tow-
ing ability and the special equipment required
for proper towing.

IAfter the hitch is removed, seal the
bolt holes to prevent exhaust fumes,
water or dust from entering the pas-
senger compartment.
IRegularly check all hitch mounting
bolts are securely mounted.
ITo reduce the possibility of additional
damage if your vehicle is struck from
the rear, where practical, remove the
hitch and/or receiver when not in use.
INever connect a trailer brake system
directly to the vehicle brake system.Tire pressuresIWhen towing a trailer, inflate the vehicle
tires to the recommended cold tire pressure
indicated on the tire placard (affixed to the
glove box lid).
ITrailer tire condition, size, load rating and
proper inflation pressure should be in ac-
cordance with the trailer and tire manufac-
turers' specifications.Safety chainsAlways use a suitable chain between yourvehicle and the trailer. The 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 lightsTrailer lights should comply with Federal
and/or local regulations.
When wiring vehicle for towing connection,
connect stop and tail light pickup into the
vehicle electrical circuit at point between
the sensor and stop light switch or light
switch.Trailer brakesIf your trailer is equipped with a braking sys-
tem, make sure it conforms to Federal and/or
local regulations and that it is properly in-
stalled.
WARNING
Never connect a trailer brake system
directly to the vehicle brake system.Trailer towing tipsIn order to gain skill and an understanding ofthe vehicle's behavior, you should practice
turning, stopping and backing up in an area
which is free from traffic. Steering stability and
braking performance will be somewhat differ-
ent than under normal driving conditions.
IAlways secure items in the trailer to prevent
load shift while driving.
IAvoid abrupt starts, acceleration or stops.
IAvoid sharp turns or lane changes.
IAlways drive your vehicle at a moderate
speed.
IAlways 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 your vehicle is equipped
with automatic transmission, first block the
wheels and apply the parking brake, and
then move the transmission selector lever
into the P position. If you move the selector
lever to the P position before blocking the
wheels and applying the parking brake,
transmission damage could occur.
IWhen going down a hill, shift into a lower
gear 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 engine over-
loading and/or overheating.
