Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carry-
ing capacity as originally equipped. (See
“Specifications”(P.9-8) for recommended
types and sizes of tires and wheels.)
WARNING
. The use of tires other than those
recommended 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, speed-
ometer calibration, headlight aim and
bumper height. Some of these effects
may lead to accidents and could result in
serious personal injury.
. If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimension.
Wheels of a different off-set could cause
premature tire wear, degrade vehicle
handling characteristics and/or interfer-
ence with the brake discs/drums. Such
interference can lead to decreased brak- ing efficiency and/or early brake pad/
shoe wear. See
“Wheels and tires” (P.9-
9) of this manual for wheel off-set
dimensions.
. When a spare tire is mounted or a wheel
is replaced, 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 retailer 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 repaired.
Such wheels or tires could have struc-
tural damage and could fail without
warning.
. The use of retread tire is not recom-
mended.
. For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or“Tire Safety Infor-
mation” (Canada) in the Warranty Infor-
mation Booklet.
All-Wheel Drive (AWD) 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
damage the transmission, transfer case
and differential gears.
. ONLY use spare tires specified for the
AWD model.
If excessive tire wear is found, it is
recommended that all four tires be re-
placed with tires of the same size, brand,
construction and tread pattern. The tire
pressure and wheel alignment should also
be checked and corrected as necessary.
Contact an INFINITI retailer.
Wheel balance
Unbalanced wheels may affect vehicle
handling and tire life. Even with regular
use, wheels can get out of balance. There-
fore, they should be balanced as required.

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 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.
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
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 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
clearance is known.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.
. Always secure items in the trailer to
prevent load shift while driving.
. Lock the trailer hitch coupler with a pin
or lock to prevent the coupler from
