●Make sure the parking area is clear of ob-
stacles and there is enough clearance over
the retractable hard top (for example, in a
garage or a covered area). More than ap-
proximately 6.6 ft (2 m) from the ground and
more than approximately 3.3 ft (1 m) from the
rear is required to open or close the retract-
able hard top safely. Otherwise, the top may
damage any objects above it while moving.
The retractable hard top operating system
could also be damaged.
● Do not operate the retractable hard top in a
strong wind. It could be blown by the wind,
striking someone or damaging the retract-
able hard top.
● When the retractable hard top is retracted,
do not allow anyone to stand up or extend
any portion of their body out of the opening
while the vehicle is in motion or while the
retractable hard top is being operated.
● In an accident you could be thrown from the
vehicle with an open retractable hard top if
you do not use seat belts. Always use seat
belts and proper child restraints. ●
Do not place any objects on or near the re-
tractable hard top operating switch. Unin-
tentional operation of the retractable hard
top may cause injuries or an accident if the
objects press the switch.
● Do not put your fingers or hands in the gap
between the rear seats and the rear parcel
shelf or the side flaps. Doing so may cause
injury if the retractable hard top is operated.
CAUTION
● Do not operate the retractable hard top when
the temperature is below 32°F (0°C). This
may result in damage to the retractable hard
top material or operating system.
● Remove water drops, snow, ice or sand from
the retractable hard top, and dry the surface
of the retractable hard top completely before
opening it.
● Do not open the retractable hard top when it
is wet or damp. If the retractable hardtop and
rear window are wet, water might get inside
of the vehicle. To avoid this, wipe off any
water drops before opening the retractable
hard top. ●
Do not place any objects between the hard
rail and the structure. Doing so could inter-
fere with retractable hard top operation and
cause damage to the retractable hard top
operating system or the objects.
● Do not place any objects on the upper area of
the windshield glass or the hard rail when
the retractable hard top is fully opened. Do-
ing so could interfere with retractable hard
top operation and cause damage.
● Do not place any object between the retract-
able hard top when the retractable hard top
is stored in the storage space. Doing so may
interfere with retractable hard top operation
and cause damage.
● Do not place anything on the retractable
hard top, rear parcel shelf, side flaps and
trunk lid. Even small items may interfere
with the retractable hard top operation and
could cause damage to the retractable hard
top or the vehicle body.
● Do not place anything in the retractable hard
top storage area. The retractable hard top
will not fit there properly, and this could
damage the retractable hard top and/or the
vehicle body.

Tire wear and damage
WARNING
●Tires should be periodically in-
spected for wear, cracking, bulging or
objects caught in the tread. If exces-
sive wear, cracks, bulging or deep
cuts are found, the tire(s) should be
replaced.
●The original tires have built-in tread
wear indicators. When wear indica-
tors are visible, the tire(s) should be
replaced.
●Tires degrade with age and use. Have
tires, including the spare, over 6
years old checked by a qualified tech-
nician, because some tire damage
may not be obvious. Replace the tires
as necessary to prevent tire failure
and possible personal injury.
●Improper service of the spare tire may
result in serious personal injury. If it
is necessary to repair the spare tire,
contact an INFINITI retailer.
●For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
Replacing wheels and tires
When replacing a tire, use the same size, tread
design, speed rating and load carrying capacity
as originally equipped. (See “SPECIFICATIONS”
in the “9. Technical and consumer information”
section for recommended types and sizes of
tires and wheels.)
WARNING
● The use of tires other than those recom-
mended or the mixed use of tires of different
brands, construction (bias, bias-belted or ra-
dial), or tread patterns can adversely affect
the ride, braking, handling, ground clear-
ance, body-to-tire clearance, tire chain
clearance, speedometer calibration, head-
light aim and bumper height. Some of these
effects may lead to accidents and could re-
sult in serious personal injury.

Spare tire (TEMPORARY USE ONLY
(T-type) spare tire) (if so equipped)
Observe the following precautions if the T-type
spare tire must be used, otherwise your vehicle
could be damaged or involved in an accident.
WARNING
●The T-type spare tire should be used for
emergency use. It should be replaced with
the standard tire at the first opportunity to
avoid possible tire or differential damage.
● Drive carefully while the TEMPORARY USE
ONLY spare tire is installed. Avoid sharp
turns and abrupt braking while driving.
● Periodically check spare tire inflation pres-
sure. Always keep the pressure of the TEM-
PORARY USE ONLY spare tire at 60 psi (420
kPa, 4.2 bar). Always keep the pressure of
the full size spare tire (if so equipped) at the
recommended pressure for standard tires,
as indicated on the Tire and Loading Infor-
mation label. For Tire and Loading Informa-
tion label location, see “Tire and Loading
Information label” in the index of this
manual.
● With the TEMPORARY USE ONLY 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 TEMPORARY USE ONLY spare tire
should be used on the front wheels and origi-
nal tire used on the rear wheels (drive
wheels). Use tire chains only on the two rear
original tires.
● Tire tread of the TEMPORARY USE ONLY
spare tire will wear at a faster rate than the
standard tire. Replace the spare tire as soon
as the tread wear indicators appear.
● 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 a TEMPORARY USE
ONLY spare tire. Tire chains will not fit prop-
erly and may cause damage to the vehicle.
● Because the TEMPORARY USE ONLY spare
tire is smaller than the original tire, ground
clearance is reduced. To avoid damage to the
vehicle, do not drive over obstacles. Also do
not drive the vehicle through an automatic
car wash since it may get caught.
