TOWING SAFETY
Trailer hitch
Check the towing capacity of your bumper hitch
or receiver-type frame mounted hitch. Choose a
proper hitch for your vehicle and trailer. A genuine
Nissan trailer hitch is available from your NISSAN
dealer. Make sure the trailer hitch is securely
attached to the vehicle to help avoid personal
injury or property damage due to sway caused by
crosswinds, rough road surfaces or passing
trucks.
CAUTION
cSpecial hitches which include frame re-
inforcements are required for towing
above 2,000 lb (907 kg) . Suitable genu-
ine NISSAN hitches for pickup trucks
and sport utility vehicles are available
at a NISSAN dealer.
cThe hitch should not be attached to or
affect the operation of the impact-
absorbing bumper.
cDo not use axle-mounted hitches.
cDo not modify the vehicle exhaust sys-
tem, brake system, etc. to install a
trailer hitch.cTo 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.
cAfter the hitch is removed, seal the bolt
holes to prevent exhaust fumes, water
or dust from entering the passenger
compartment.
cRegularly check that all trailer hitch
mounting bolts are securely mounted.
Tire pressures
cWhen towing a trailer, inflate the vehicle tires
to the recommended cold tire pressure indi-
cated on the tire placard.
cTrailer tire condition, size, load rating and
proper inflation pressure should be in accor-
dance with the trailer and tire manufacturer’s
specifications.
Safety chains
Always use suitable safety chains between your
vehicle and the trailer. Safety chains 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 chains to permit turning
corners.
Trailer lights
Trailer lights should comply with federal and/or
local regulations. For assistance in hooking up
trailer lights, contact a NISSAN dealer.
Trailer brakes
If 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 di-
rectly to the vehicle brake system.
Pre-towing tips
cBe certain your vehicle maintains a level posi-
tion 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.
cAlways secure items in the trailer to prevent
load shift while driving.
cBe certain your rear view mirrors conform to all
federal, state or local regulations. If not, install
any mirrors required for towing before driving
the vehicle.

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.
