2014 INFINITI Q50-HYBRID spare wheel

To shut off the INFINITI Direct Response
Hybrid®System in an emergency situation
while driving, perform the following proce-
dure:
. Rapidly push the push-button ignition
switch 3 consecutive times in less than
1.5 seconds, or
. Push and hold the push-button ignition
switch for more than 2 seconds. Your vehicle is equipped with run-flat tires
and you can continue driving to a safe
location even if they are punctured. (See
“Run-flat tires”
(P.8-36).)
TIRE PRESSURE MONITORING SYS-
TEM (TPMS)
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires except
the spare. When the low tire pressure
warning light is lit and the “Tire Pressure
Low - Add Air” warning appears in the
vehicle information display, one or more of
your tires is significantly under-inflated. If
the vehicle is being driven with low tire
pressure, the TPMS will activate and warn
you of it by the low tire pressure warning
light. This system will activate only when
the vehicle is driven at speeds above 16
MPH (25 km/h). For more details, see “Low
tire pressure warning light” (P.2-15) and
“Tire Pressure Monitoring System (TPMS)”
(P.5-4).
WARNING
. Radio waves could adversely affect
electric medical equipment. Those who
use a pacemaker should contact the electric medical equipment manufacturer
for the possible influences before use.
. If the low tire pressure warning light
illuminates while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road to
a safe location and stop the vehicle as
soon as possible. Driving with under-
inflated tires may permanently damage
the tires and increase the likelihood of
tire failure. Serious vehicle damage
could occur and may lead to an accident
and could result in serious personal
injury. Check the tire pressure for all
four tires. Adjust the tire pressure to the
recommended COLD tire pressure shown
on the Tire and Loading Information
label to turn the low tire pressure
warning light OFF. If the light still
illuminates while driving after adjusting
the tire pressure, a tire may be flat.
. When a wheel is replaced, the TPMS will
not function and the low tire pressure
warning light will flash for approxi-
mately 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.

transmitter components: Replace the TPMS
transmitter grommet seal, valve core and
cap when the tires are replaced due to
wear or age.
Tire, wheel alignment and balance: If thevehicle should pull to either side while
driving on a straight and level road, or if
you detect uneven or abnormal tire wear,
there may be a need for wheel alignment.
If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing
may be needed.
For additional information regarding tires,
refer to
“Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada)
in the INFINITI Warranty Information Book-
let.
Windshield: Clean the windshield on a
regular basis. Check the windshield at
least every six months for cracks or other
damage. Have a damaged windshield
repaired by a qualified repair facility.
Windshield wiper blades*: Check for
cracks or wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should
be checked on a regular basis, such as
when performing periodic maintenance,
cleaning the vehicle, etc.
Accelerator pedal: Check the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort. Keep the floor mat away from the pedal.
Automatic transmission P (Park) mechan-
ism:
On a fairly steep hill, check that your
vehicle is held securely with the shift lever
in the P (Park) position without applying
any brakes.
Brake pedal: Check the pedal for smooth
operation. If the brake pedal suddenly
goes down further than normal, the pedal
feels spongy or the vehicle seems to take
longer to stop, see an INFINITI retailer
immediately. Keep the floor mat away from
the pedal.
Brakes: Check that the brakes do not pull
the vehicle to one side when applied.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only
the parking brake applied. If the parking
brake needs adjusted, see an INFINITI
retailer.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, an-
chors, adjuster and retractors) operate
properly and smoothly, and are installed
securely. Check the belt webbing for cuts,
fraying, wear or damage.
Seats: Check seat position controls such as

TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires except
the spare. When the low tire pressure
warning light is lit and the “Tire Pressure
Low - Add Air” warning appears in the
vehicle information display, one or more of
your tires is significantly under-inflated.
The TPMS will activate only when the
vehicle is driven at speeds above 16 MPH
(25 km/h). Also, this system may not
detect a sudden drop in tire pressure (for
example a flat tire while driving).
For more details, see “Low tire pressure
warning light” (P.2-15),“Tire Pressure Mon-
itoring System (TPMS)” (P.5-4) and“Tire
Pressure Monitoring System (TPMS)” (P.6-
3).
Tire inflation pressure
Check the pressure of the tires
(including the spare) often and al- ways prior to long distance trips. The
recommended tire pressure specifi-
cations are shown on the Tire and
Loading Information label under the
“Cold Tire Pressure”
heading. The
Tire and Loading Information label is
affixed to the driver side center pillar.
Tire pressures should be checked
regularly because:
.Most tires naturally lose air over time.
.Tires can lose air suddenly whendriven over potholes or other
objects or if the vehicle strikes a
curb while parking.
The tire pressures should be checked
when the tires are cold. The tires are
considered COLD after the vehicle
has been parked for 3 or more hours,
or driven less than 1 mile (1.6 km) at
moderate speeds.
TPMS with Tire Inflation Indicator
provides visual and audible signals
outside the vehicle for inflating the
tires to the recommended COLD tire pressure. (See
“TPMS with Tire Infla-
tion Indicator” (P.5-7) about the
TPMS with Tire Inflation Indicator.)
Incorrect tire pressure, including
under inflation, may adversely affect
tire life and vehicle handling.
WARNING
. Improperly inflated tires can fail
suddenly and cause an accident.
. The Gross Vehicle Weight rating
(GVWR) is located on the F.M.V.S.
S./C.M.V.S.S. label. The vehicle
weight capacity is indicated on
the Tire and Loading Information
label. Do not load your vehicle
beyond this capacity. Overloading
your vehicle may result in reduced
tire life, unsafe operating condi-
tions due to premature tire failure,
or unfavorable handling character-
istics and could also lead to a
serious accident. Loading beyond
the specified capacity may also

Tire wear and damage
WARNING
.Tires should be periodically in-
spected for wear, cracking, bul-
ging or objects caught in the
tread. If excessive 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
indicators 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 technician, because
some tire damage may not be
obvious. Replace the tires as
necessary to prevent tire failure
and possible personal injury.
. For additional information regard-
ing tires, refer to “Important Tire
Safety Information ”(US) or “Tire
Safety Information ”(Canada) in
the Warranty Information Booklet.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, radial or run-flat), or tread
patterns can adversely affect the ride,
braking, handling, ground clearance,
body-to-tire clearance, tire chain clear-
ance, speedometer calibration, head-
light aim and bumper height. Some of
these effects may lead to accidents and
could result in serious personal injury.
. For Two-Wheel Drive (2WD) models, 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
accident and 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-
