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.
cAlways secure items in the trailer to prevent
load shift while driving.
cAvoid 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,
and if your vehicle is equipped with an auto-
matic transmission, first block the wheels and
apply the parking brake, and then move the
transmission shift selector lever 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 lower gear
and use the engine braking effect. When go-
ing up a long grade, downshift the transmis-
sion to a lower gear and reduce speed toreduce chances of engine overloading and/or
overheating. However, for long steep grades,
do not stay in 1st or 2nd gear when driving
above 35 MPH (56 km/h) .
cIf the engine coolant rises to an extremely high
temperature when the air conditioner system
is on, turn off the air conditioner. Coolant heat
can be additionally vented by opening the win-
dows, switching the fan control to high and
setting the temperature control to the HOT
position.
cTrailer towing requires more fuel than normal
circumstances.
cAvoid towing a trailer for your vehicle’s first
500 miles (805 km) .
cHave your vehicle serviced more often than at
intervals specified in the recommended Main-
tenance 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.
cCrosswinds 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. If swaying does occur, firmly
grip the steering wheel, steer straight ahead,
and immediately (but gradually) reduce vehicle
speed. This combination will help stabilize the
vehicle. Never increase speed.
cBe careful when passing other vehicles. Pass-
ing while towing a trailer requires considerably
more distance than normal passing. Remem-
ber, the length of the trailer must also pass the
other vehicle before you can safely change
lanes.
cTo maintain engine braking efficiency and
electrical charging performance, do not use
5th gear (manual transmission) or overdrive
(automatic transmission) .
cAvoid holding the brake pedal down too long
or too frequently. This could cause the brakes
to overheat, resulting in reduced braking effi-
ciency.
When towing a trailer, transmission
oil/fluid should be changed more fre-
quently. For additional information, see the
“Maintenance and do-it-yourself” section
earlier in this manual.

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
Treadwear grade is a comparative rating based
on tire wear rate when tested under controlled
conditions on specified government test courses.
For example, a tire graded 150 would wear one
and a half (1-1/2) times as well on the govern-
ment course as a tire graded 100. However,
relative tire performance depends on actual driv-
ing conditions, and may vary significantly 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 your ve-
hicle tires is based on straight-ahead
braking traction tests and does not in-
clude acceleration, cornering, hydroplan-
ing or peak traction characteristics.
Temperature A, B and C
Temperature grades are A (the highest) , B, and
C. They represent a tire’s resistance to heat
build-up, and its ability to dissipate heat when
tested under controlled conditions on a specified
indoor laboratory test wheel. Sustained high tem-
perature can cause tire material to degenerate,
reducing tire life. Excessive temperatures can
lead to sudden tire failure. Grade C corresponds
to a performance level which all passenger car
tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades A and B rep-
resent higher levels of performance on laboratory
test wheels than the minimum required by law.
WARNING
The temperature grade for this tire is es-
tablished for a tire that is properly inflated
and not overloaded. Excessive speed,
under-inflation, or excessive loading, ei-
ther separately or in combination, can
cause heat build-up and possible tire
failure.

IN THE EVENT OF A COLLISION
Unfortunately, accidents do occur. In this unlikely
event, there is some important information you
should know.
Many insurance companies routinely authorize
the use of non-genuine collision parts in order to
cut costs, among other reasons.
Insist on the use of genuine NISSAN
collision parts!
If you want your vehicle to be restored using parts
made to NISSAN’s original exacting specifica-
tions – if you want to help it to last and hold its
resale value, the solution is simple.Tell your
insurance agent and your repair shop to
only use Genuine NISSAN Collision Parts.
NISSAN does not warrant non-NISSAN parts,
nor does NISSAN’s warranty apply to damage
caused by a non-genuine part.
Using Genuine NISSAN Parts can help protect
your personal safety, preserve your warranty pro-
tection and maintain the resale value of your
vehicle. And if your vehicle was leased, using
Genuine NISSAN Parts may prevent or limit un-
necessary excess wear and tear expenses at the
end of your lease.
NISSAN designs its hoods with crumple zones to
minimize the risk that the hood will penetrate the
windshield of your vehicle in an accident. Non-
genuine (imitation) parts may not provide such
built in safeguards. Also, non-genuine parts often
show premature wear, rust and corrosion.
Why should you take a chance?
In over 40 states, the law says you must be
advised if non-genuine parts are used to repair
your vehicle. And some states have enacted lawsthat restrict insurance companies from authoriz-
ing the use of non-genuine collision parts during
the new vehicle warranty. These laws help pro-
tect you, so you can take action to protect your-
self.
It’s your right!
