. Periodically check spare tire inflation
pressure. Always keep the spare tire
inflated to the pressure specification
shown on the Tire and Loading Informa-
tion label. For Tire and Loading Informa-
tion label location, see “Tire and Loading
Information label” in the index of this
manual.
. With the spare tire installed do not drive
your vehicle at speeds faster than 50
MPH (80 km/h).
. When driving on roads covered with
snow or ice, the spare tire should be
used on the front wheels and original
tire used on the rear wheels (drive
wheels). Use tire chains only on the
two rear original tires.
. Do not use the spare tire on other
vehicles.
. Do not use more than one spare tire at
the same time.
CAUTION
Do not use tire chains on the spare tire. Tire
chains will not fit properly and may cause
damage to the vehicle.

3.Subtract the combined weight of
the driver and passengers from
XXX kg or XXX lbs.
4.The resulting figure equals the
available amount of cargo and
luggage load capacity. For exam-
ple, if the XXX amount equals
1400 lbs. and there will be five
150 lb. passengers in your vehi-
cle, the amount of available cargo
and luggage load capacity is 650
lbs. (1400−750 (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.
6.If your vehicle will be towing a
trailer, load from your trailer will
be transferred to your vehicle.
Consult this manual to determine
how this reduces the available cargo and luggage load capacity
of your vehicle.
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 “Mea-
surement of weights” later in this
section.)
Also check tires for proper inflation
pressures. See the Tire and Loading
Information label.

SECURING THE LOAD
There are tie down hooks located in the
cargo area as shown. The tie down hooks
can be used to secure cargo with ropes or
other types of straps.
Do not apply a total load of more than 22
lb (10 kg) to a single hook
*Aor 7 lb (3 kg)
to a single hook
*Bwhen securing cargo.
WARNING
. Properly secure all cargo with ropes or
straps to help prevent it from sliding or
shifting. Do not place cargo higher than

10,000 lb (4,545 kg). A weight distributing
hitch should be used to tow trailers that
weigh over 5,000 lb (2,267 kg).
Your vehicle may be equipped with Class IV
trailer hitch equipment that has a 10,000
lb (4,545 kg) maximum weight rating, but
your vehicle is only capable of towing the
maximum trailer weights shown in the
“Towing Load/Specification”chart earlier
in this section.
CAUTION
. Do not use axle-mounted hitches.
. Do not modify the vehicle exhaust
system, brake system, etc.
. Do not attach any additional hitches to
your vehicle because a hitch is already
mounted to your vehicle frame.
Tire pressures
.When towing a trailer, inflate the
vehicle tires to the recommended
cold tire pressure indicated on the
Tire and Loading Information la-
bel.
.Trailer tire condition, size, loadrating and proper inflation pres-
sure should be in accordance with
the trailer and tire manufacturers’
specifications.
Safety chains
Always use a suitable chain between your
vehicle and the trailer. The 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
Your vehicle is equipped with a towing
package, which also includes the 7-pin
trailer harness connector located under the
trailer hitch cover on the rear bumper.
CAUTION
. When splicing into the vehicle electrical
system, a commercially available power-
type module/converter must be used to
provide power for all trailer lighting. This
unit uses the vehicle battery as a direct
power source for all trailer lights while
Technical and consumer information9-25

9-26Technical and consumer information
using the vehicle tail light, stoplight and
turn signal circuits as a signal source.
The module/converter must draw no
more than 15 milliamps from the stop
and tail lamp circuits. Using a module/
converter that exceeds these power
requirements may damage the vehicle’s
electrical system. See a reputable trailer
retailer to obtain the proper equipment
and to have it installed.
. Do not connect electrical devices that
draw more than 40 amps to the vehicle.
The fusible link may melt.
Trailer lights should comply with federal
and/or local regulations. For assistance in
hooking up trailer lights, contact an
INFINITI retailer or reputable trailer retailer.
Trailer brakes
When towing a trailer load of 3,500 lbs.
(1,587 kg) or more, trailers with a brake
system MUST be used. However, most
states require a separate braking system
on trailers with a loaded weight above a
specific amount. Make sure the trailer
meets the local regulations and the regula-
tions where you plan to tow.
Several types of braking systems are available.
Surge Brakes -
The surge brake actuator is
mounted on the trailer tongue with a
hydraulic line running to each trailer
wheel. Surge brakes are activated by the
trailer pushing against the hitch ball when
the tow vehicle is braking. Hydraulic surge
brakes are common on rental trailers and
some boat trailers. In this type of system,
there is no hydraulic or electric connection
for brake operation between the tow
vehicle and the trailer.
Electric Trailer Brakes - Electric braking
systems are activated by an electronic
signal sent from a trailer brake controller
(special brake sensing module).
Have a professional supplier of towing
equipment make sure the trailer brakes are
properly installed and demonstrate proper
brake function testing.
WARNING
Never connect a trailer brake system directly
to the vehicle brake system.
Pre-towing tips
. Be certain your vehicle maintains a level
position when a loaded 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.
. Always secure items in the trailer to
prevent load shift while driving.
. Keep the cargo load as low as possible
in the trailer to keep the trailer center of
gravity low.
. Load the trailer so approximately 60%
of the trailer load is in the front half and
40% is in the back half. Also make sure
the load is balanced side to side.
. Check your hitch, trailer tire pressure,
vehicle tire pressure, trailer light opera-
tion, and trailer wheel lug nuts every
time you attach a trailer to the vehicle.
. Be certain your rearview mirrors con-
form to all federal, state or local
regulations. If not, install any mirrors
required for towing before driving the
vehicle.
. Determine the overall height of the
vehicle and trailer so the required
