Other Tire-related Terminology
In addition to the many terms that are
defined throughout this section, Intended
Outboard Sidewall is (1) the sidewall that
contains a whitewall, bears white lettering
or bears manufacturer, brand, and/or
model name molding that is higher or
deeper than the same molding on the
other sidewall of the tire, or (2) the out-
ward facing sidewall of an asymmetrical
tire that has a particular side that must
always face outward when mounted on a
vehicle.
TYPES OF TIRES
WARNING
● When changing or replacing tires, be
sure all four tires are of the same type
(i.e., Summer, All Season or Snow) and
construction. An INFINITI dealer may be
able to help you with information about
tire type, size, speed rating and
availability.
● Replacement tires may have a lower
speed rating than the factory equipped
tires, and may not match the potential
maximum vehicle speed. Never exceed
the maximum speed rating of the tire.
● Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the low tire pres-
sure warning system.
● For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Informa-
tion” (Canada) in the Warranty Informa-
tion Booklet.
All season tires
INFINITI specifies All Season tires on some mod-
els to provide good performance all year, includ- ing snowy and icy road conditions. All Season
tires are identified by ALL SEASON and/or M&S
on the tire sidewall. Snow tires have better snow
traction than All Season tires and may be more
appropriate in some areas.
Summer tires
INFINITI specifies summer tires on some models
to provide superior performance on dry roads.
Summer tire performance is substantially re-
duced in snow and ice. Summer tires do not have
the tire traction rating “M&S” on the tire sidewall.
If you plan to operate your vehicle in snowy or icy
conditions, INFINITI recommends the use of
SNOW tires or ALL SEASON tires on all four
wheels.
Snow tires
If snow tires are needed, it is necessary to select
tires equivalent in size and load rating to the
original equipment tires. If you do not, it can
adversely affect the safety and handling of your
vehicle.
Generally, snow tires have lower speed ratings
than factory equipped tires and may not match
the potential maximum vehicle speed. Never ex-
ceed the maximum speed rating of the tire.

If you install snow tires, they must be the same
size, brand, construction and tread pattern on all
four wheels.
For additional traction on icy roads, studded tires
may be used. However, some U.S. states and
Canadian provinces prohibit their use. Check
local, state and provincial laws before installing
studded tires. Skid and traction capabilities of
studded snow tires on wet or dry surfaces may be
poorer than that of non-studded snow tires.
TIRE CHAINS
CAUTION
Tire chains/cables should not be installed
on P275/60R20 size tires. Installation of
the tire chains/cables on P275/60R20 size
tires will cause damage to the vehicle. If
you plan to use tire chains/cables, you
should install P265/70R18 size tires on
your vehicle.
Use of tire chains may be prohibited according to
location. Check the local laws before installing
tire chains. When installing tire chains, make sure
they are the proper size for the tires on your
vehicle and are installed according to the chain
manufacturer’s suggestions. Use only SAE
class “S” chains. Class “S” chains are used on
vehicles with restricted tire to vehicle clearance.
Vehicles that can use Class “S” chains are de- signed to meet the minimum clearances between
the tire and the closest vehicle suspension or
body component required to accommodate the
use of a winter traction device (tire chains or
cables) . The minimum clearances are determined
using the factory equipped tire size. Other types
may damage your vehicle. Use chain tensioners
when recommended by the tire chain manufac-
turer to ensure a tight fit. Loose end links of the
tire chain must be secured or removed to prevent
the possibility of whipping action damage to the
fenders or underbody. If possible, avoid fully load-
ing your vehicle when using tire chains. In addi-
tion, drive at a reduced speed. Otherwise, your
vehicle may be damaged and/or vehicle handling
and performance may be adversely affected.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Do not use tire chains on dry roads. Driving with
chains in such conditions can cause damage to
the various mechanisms of the vehicle due to
some overstress.
Use only the 2WD range when driving on clear
paved roads.CHANGING WHEELS AND TIRES
Tire rotation
INFINITI recommends rotating the tires
every 7,500 miles (12,000 km) .
See “Flat tire” in the “In case of emer-
gency” section in this manual for tire re-
placing procedures.
As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.

Replacing wheels and tires
When replacing a tire, use the same size, tread
design, speed rating and load carrying capacity
as originally equipped. Recommended types and
sizes are shown in “Wheels and tires” in the
“Technical and consumer information” section of
this manual.
WARNING
●The use of tires other than those recom-
mended or the mixed use of tires of
different brands, construction (bias,
bias-belted or radial) , or tread patterns
can adversely affect the ride, braking,
handling, ground clearance, body-to-
tire clearance, tire chain clearance,
speedometer calibration, headlight aim
and bumper height. Some of these ef-
fects may lead to accidents and could
result in serious personal injury.
● If your vehicle was originally equipped
with 4 tires that were the same size and
you are only replacing 2 of the 4 tires,
install the new tires on the rear axle.
Placing new tires on the front axle may
cause loss of vehicle control in some
driving conditions and cause an acci-
dent and personal injury. ●
If the wheels are changed for any rea-
son, always replace with wheels which
have the same off-set dimension.
Wheels of a different off-set could
cause premature tire wear, degrade ve-
hicle handling characteristics and/or
interference with the brake
discs/drums. Such interference can
lead to decreased braking efficiency
and/or early brake pad/shoe wear. Re-
fer to “Wheels and tires” in the “Techni-
cal and consumer information” section
of this manual for wheel off-set
dimensions.
● When a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your INFINITI dealer as soon as
possible for tire replacement and/or
system resetting.
● Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS. ●
Do not install a damaged or deformed
wheel or tire even if it has been re-
paired. Such wheels or tires could have
structural damage and could fail with-
out warning.
● The use of retread tires is not
recommended.
● For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Informa-
tion” (Canada) in the Warranty Informa-
tion Booklet.
Four-wheel drive models
CAUTION
Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial) , and tread pattern on all four
wheels. Failure to do so may result in a
circumference difference between tires
on the front and rear axles which will
cause excessive tire wear and may dam-
age the transmission, transfer case and
differential gears.

5. Determine the combined weight ofluggage 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 trans-
ferred to your vehicle. Consult this
manual to determine how this re-
duces the available cargo and lug-
gage 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 “Measurement of Weights” later in
this section.
Also check tires for proper inflation pres-
sures. See the Tire and Loading Informa-
tion 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 55
lbs. (245 N) to a single
Aplastic hook or 44
lbs. (196 N) to a single
Bplastic hook
when securing cargo.
Do not apply a total load of more than 110
lbs. (490 N) to a single metal floor tie-down
hook when 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
the seatbacks. In a sudden stop or col-
lision, unsecured cargo could cause
personal injury.
● The child restraint top tether strap may
be damaged by contact with items in
the cargo area. Secure any items in the
cargo area. Your child could be seri-
ously injured or killed in a collision if
the top tether strap is damaged.

CAUTION
●Special hitches which include frame re-
inforcements are required for towing
above 2,000 lb (907 kg) . Suitable genu-
ine INFINITI hitches, ball mounts and
hitch balls for pickup trucks and sport
utility vehicles are available at an
INFINITI dealer.
● The hitch should not be attached to or
affect the operation of the impact-
absorbing bumper.
● Do not use axle-mounted hitches.
● Do not modify the vehicle exhaust sys-
tem, brake system, etc. to install a
trailer hitch.
● To reduce the possibility of additional
damage if your vehicle is struck from
the rear, where practical, remove the
receiver when not in use.
● Regularly check that all trailer hitch
mounting bolts are securely mounted.
● When towing with the hitch ball
mounted to the rear bumper, do not
make sharp turns. The trailer may con-
tact the bumper and cause damage to
the bumper or trailer.
Tire pressures
● When towing a trailer, inflate the ve-
hicle tires to the recommended cold
tire pressure indicated on the tire
placard.
● Trailer tire condition, size, load rating
and proper inflation pressure should
be in accordance with the trailer and
tire manufacturer’s specifications.
Safety chains
Always use suitable safety chains 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. The safety
chains can be attached to the bumper if the hitch
ball is mounted to the bumper. Be sure to leave
enough slack in the chains to permit turning
corners.
Trailer lights
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
using the vehicle tail light, stoplight and
turn signal circuits as a signal source. The
module/converter must draw no more
that 15 milliamps from the stop and tail
lamp circuits. Using a module/converter
that exceeds these power requirements
may damage the vehicle’s electrical sys-
tem. See a reputable trailer dealer to ob-
tain the proper equipment and to have it
installed.
Trailer lights should comply with federal and/or
local regulations. For assistance in hooking up
trailer lights, contact an INFINITI dealer or repu-
table trailer dealer. Vehicles equipped with the
optional trailer tow package are equipped with a
7-pin trailer harness connector. If your trailer is
equipped with a flat 4-pin connector, an adapter
will be needed to connect the trailer lights to the
vehicle. Adapters are available at auto parts
stores and hitch retailers.
