2014 INFINITI Q50 warning light

maged from wind pressure.If the brakes do not operate properly, have
the brakes checked by an INFINITI retailer.
SELF-ADJUSTING BRAKES
Your vehicle is equipped with self-adjust-
ing brakes.
The disc-type brakes self-adjust every time
the brake pedal is applied.
WARNING
See an INFINITI retailer for a brake system
check if the brake pedal height does not
return to normal.
BRAKE PAD WEAR WARNING
The disc brake pads have audible wear
warnings. When a brake pad requires
replacement, it will make a high pitched
scraping sound when the vehicle is in
motion. This scraping sound will first occur
only when the brake pedal is depressed.
After more wear of the brake pad, the
sound will always be heard even if the
brake pedal is not depressed. Have the
brakes checked as soon as possible if the
wear warning sound is heard.
Under some driving or climate conditions,occasional brake squeak, squeal or other
noise may be heard. Occasional brake
noise during light to moderate stops is
normal and does not affect the function or
performance of the brake system.
Proper brake inspection intervals should
be followed.
For additional information,
see the maintenance log section of your
“INFINITI Service and Maintenance Guide”
for maintenance intervals.

CAUTION
Never use a fuse of a higher or lower
amperage rating than that specified on the
fuse box cover. This could damage the
electrical system or cause a fire.
If any electrical equipment does not
operate, check for an open fuse.
1. Be sure the ignition switch is pushed tothe OFF or LOCK position and the
headlight switch is turned to OFF. 2. Open the fuse box lid.
3. Remove the fuse with the fuse puller
*A.
4. If the fuse is open, replace it with a new fuse.
5. If a new fuse also opens, have the electrical system checked and repaired
by an INFINITI retailer. Spare fuses are
stored in the fuse box.

Extended storage fuse switch (if so
equipped)
To reduce battery drain, the extended
storage fuse switch comes from the factory
switched off. Prior to delivery of your
vehicle, the switch is pushed in (switched
on) and should always remain on.
If the extended storage fuse switch is not
pushed in (switched on), the “Shipping
Mode On, Push Storage Fuse” warning may
appear in the vehicle information display.

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.2-14),“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

Run-flat tires
Your vehicle is equipped with run-flat tires.
You can continue driving to a safe location
even if they are punctured. Always use run-
flat tires of the specified size on all four
wheels. Mixing tire sizes or construction
may reduce vehicle handling stability. If
necessary, contact an INFINITI retailer for
assistance.
Frequently check the tire pressure and
adjust pressure of each tire properly. The
tire pressure can be also checked in the
vehicle information display.
It can be difficult to tell if a run-flat tire is
under-inflated or flat. Check the tire
pressures as described earlier in this
section. If the tire becomes under-inflated
while driving, the low tire pressure warning
light will illuminate. If the tire becomes flat
while driving, the low tire pressure warning
light and the“Flat Tire - Visit dealer”
warning will appear.
Low tire pressure:
If the vehicle is being driven with low tire
pressure, the low tire pressure warning
light will illuminate. Flat tire:
If the vehicle is being driven with one or
more flat tires, the low tire pressure
warning light will illuminate continuously
and a chime will sound for 10 seconds. A
“ Flat Tire - Visit dealer” warning also
appears in the vehicle information display.
The chime will only sound at the first
indication of a flat tire and the warning
light will illuminate continuously. When the
flat tire warning is activated, have the
system reset and the tire checked and
replaced if necessary by an INFINITI retai-
ler. Even if the tire is inflated to the
specified COLD tire pressure, the warning
light will continue to illuminate until the
system is reset by an INFINITI retailer.
If the low tire pressure warning light
illuminates continuously and the “Flat Tire
- Visit dealer” warning appears in the
vehicle information display:
. Do not exceed 50 MPH (80 km/h).
. Increase your following distance to
allow for increased stopping distances.
. Avoid sudden maneuvers, hard corner-
ing and hard braking.WARNING
. Although you can continue driving with a
punctured run-flat tire, remember that
vehicle handling stability is reduced,
which could lead to an accident and
personal injury. Also, driving a long
distance at high speeds may damage
the tire.
. Do not drive at speeds above 50 MPH
(80 km/h) and do not drive more than
approximately 93 miles (150 km) with a
punctured run-flat tire. The actual dis-
tance the vehicle can be driven on a flat
tire depends on outside temperature,
vehicle load, road conditions and other
factors.
. Drive safely at reduced speeds. Avoid
hard cornering or braking, which may
cause you to lose control of the vehicle.
. If you detect any unusual sounds or
vibrations while driving with a punctured
run-flat tire, pull off the road to a safe
location and stop the vehicle as soon as
possible. The tire may be seriously
damaged and need to 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.
. 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 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-
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

361-4792.WARNING
A vehicle equipped with Intelligent All-
Wheel Drive (AWD) should never be tested
using a two wheel dynamometer (such as
the dynamometers used by some states for
emissions testing), or similar equipment.
Make sure you inform test facility personnel
that your vehicle is equipped with AWD
before it is placed on a dynamometer. Using
the wrong test equipment may result in
transmission damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury.
Due to legal requirements in some states/
areas, your vehicle may be required to be
in what is called the“ready condition”for
an Inspection/Maintenance (I/M) test of
the emission control system.
The vehicle is set to the “ready condition”
when it is driven through certain driving
patterns. Usually, the “ready condition”
can be obtained by ordinary usage of the
vehicle.
If a powertrain system component is
repaired or the battery is disconnected,
the vehicle may be reset to a “not readycondition”
. Before taking the I/M test,
check the vehicle’ s inspection/mainte-
nance test readiness condition. Place the
ignition switch in the ON position without
starting the engine. If the Malfunction
Indicator Light (MIL) comes on steady for
20 seconds and then blinks for 10
seconds, the I/M test condition is “not
ready”. If the MIL does not blink after 20
seconds, the I/M test condition is “ready”.
Contact an INFINITI retailer to set the
“ready condition” or to prepare the vehicle
for testing.
