2019 INFINITI Q50 engine

To shut off the engine in an emergency
situation while driving, perform the follow-
ing procedure:
.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. If you have a flat tire, follow the instructions
in this section.
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 informa-
tion 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 “Warning lights, in-
dicator lights and audible reminders” (P.2-
10) and “Tire Pressure Monitoring System
(TPMS)” (P.5-5).
WARNING
.
Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment man-
ufacturer for the possible influences
before use. .
If the low tire pressure warning light
illuminates while driving, avoid sud-
den 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. If you have a flat tire,
replace it with a spare tire (if so
equipped).
. Since the spare tire is not equipped
with the TPMS, 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. Have
your tires replaced and/or TPMS
system reset as soon as possible. It

is recommended you visit an INFINITI
retailer for these services.
. Replacing tires with those not origin-
ally specified by INFINITI could affect
the proper operation of the TPMS.
. Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pres-
sure sensors.
RUN-FLAT TIRES (if so equipped)
Run-flat tires are those tires that can be
used temporarily if they are punctured. See
“Run-flat tires” (P.8-40).
Also, refer to “Important Tire Safety Infor-
mation” (US) or “Tire Safety Information”
(Canada) in the INFINITI Warranty Informa-
tion Booklet.
WARNING
.Although you can continue driving
with a punctured run-flat tire, re-
member that vehicle handling stabi-
lity is reduced, which could lead to an
accident and personal injury. Also,
driving a long distance at high speeds
may damage the tires. .
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 distance 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 punc-
tured 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.
CAUTION
.Never install tire chains on a punctu-
red run-flat tire, as this could damage
your vehicle.
. Avoid driving over any projection or
pothole, as the clearance between
the vehicle and the ground is smaller
than normal. .
Do not enter an automated car wash
with a punctured run-flat tire.
. It is recommended you have the
punctured tire inspected by an
INFINITI retailer or other authorized
repair shop. Replace the tire as soon
as possible if the tire is seriously
damaged.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions
in this section to replace the tire with a spare
tire (if so equipped). For the vehicles with
run-flat tires, you can continue driving to a
safe location even if they are punctured. (See
“Run-flat tires” (P.6-4) and “Run-flat tires”
(P.8-40).)
This section also contains the information
about the vehicle jack-up procedures.
Stopping the vehicle
1. Safely move the vehicle off the road and
away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Move the shift lever to the
P (Park) position.
4. Turn off the engine.

Jacking up the vehicle and removing
the damaged tire
WARNING
. Never get under the vehicle while it is
supported only by the jack. If it is
necessary to work under the vehicle,
support it with safety stands.
. Use only the jack provided with your
vehicle to lift the vehicle. Do not use
the jack provided with your vehicle on
other vehicles. The jack is designed
for lifting only your vehicle during a
tire change.
. Use the correct jack-up points. Never
use any other part of the vehicle for
jack support.
. Never jack up the vehicle more than
necessary.
. Never use blocks on or under the jack.
. Do not start or run the engine while
vehicle is on the jack, as it may cause
the vehicle to move. This is especially
true for vehicles with limited slip
differentials.
. Do not allow passengers to stay in
the vehicle while it is on the jack. Carefully read the caution label attached to
the jack body and the following instruc-
tions.

5. Securely store the flat tire and jackingequipment in the vehicle.
6. Place the spare tire cover (if so equipped) and the trunk floor carpeting over the
damaged tire.
7. Close the trunk.
WARNING
. Always make sure that the spare tire
(if so equipped) and jacking equip-
ment are properly secured after use.
Such items can become dangerous
projectiles in an accident or sudden
stop. .
The T-type spare tire and small size
spare tire (if so equipped) are de-
signed for emergency use. See spe-
cific instructions under the heading
“Wheels and tires” (P.8-33). To start your engine with a booster battery,
the instructions and precautions below must
be followed.
WARNING
.
If done incorrectly, jump starting can
lead to a battery explosion, resulting
in severe injury or death. It could also
damage your vehicle.
. Explosive hydrogen gas is always
present in the vicinity of the battery.
Keep all sparks and flames away from
the battery.
. Do not allow battery fluid to come
into contact with eyes, skin, clothing
or painted surfaces. Battery fluid is a
corrosive sulphuric acid solution
which can cause severe burns. If the
fluid should come into contact with
anything, immediately flush the con-
tacted area with water.
. Keep the battery out of the reach of
children.
. The booster battery must be rated at
12 volts. Use of an improperly rated
battery can damage your vehicle.
. Whenever working on or near a
battery, always wear suitable eye
protectors (for example, goggles or

industrial safety spectacles) and re-
move rings, metal bands, or any other
jewelry. Do not lean over the battery
when jump starting.
. Do not attempt to jump start a
frozen battery. It could explode and
cause serious injury.
. Your vehicle has an automatic engine
cooling fan. It could come on at any
time. Keep hands and other objects
away from it.
For 2.0L turbo gasoline engine models:
The vehicle has 2 batteries, a main
battery and an auxiliary battery. The
engine cannot be started if either bat-
tery is discharged. First, apply the
following procedure to the main battery
to jump-start the engine.
If the engine does not start, apply the
procedure to the auxiliary battery. For
the position of the batteries, see “Engine
compartment check locations” (P.8-4)
or “Battery” (P.8-16).
. Use the special battery that is dedi-
cated for the Idling Stop System,
with enhanced charge-discharge ca-
pacity and life performance. Using
the non-special battery could cause
early deterioration of the battery
and/or malfunction of the Idling Stop System. For the special battery, it is
recommended to use Genuine
NISSAN parts. For more information,
it is recommended you contact an
INFINITI retailer.
. It may take some time until the Idling
Stop System activates when the
battery is replaced or the battery
terminal is disconnected for extended
periods and then reconnected.
