When planning to drive your NISSAN ve-
hicle in another country,you should first find
out if the fuel available is suitable for your vehi-
cle’s engine.
Using fuel with an octane rating that is too low
may cause engine damage. All gasoline vehicles
must be operated with unleaded gasoline. There-
fore, avoid taking your vehicle to areas where
appropriate fuel is not available.
When transferring the registration of your
vehicle to another country, state, province
or district,it may be necessary to modify the
vehicle to meet local laws and regulations.
The laws and regulations for motor vehicle emis-
sion control and safety standards vary according
to the country, state, province or district; there-
fore, vehicle specifications may differ.
When any vehicle is to be taken into an-
other country, state, province or district
and registered, its modifications, transpor-
tation, and registration are the responsibil-
ity of the user. NISSAN is not responsible
for any inconvenience that may result.

Trailer 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
cDo not use axle-mounted hitches.
cThe hitch should not be attached to or
affect the operation of the impact-
absorbing bumper.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.
