2018 INFINITI Q50 HYBRID warning

6-4In case of emergency
.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
Run-flat tires are those tires that can be
used temporarily if they are punctured. See
“Run-flat tires” (P.8-34).
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.
If you have a flat tire and have to stop the
vehicle, follow the instructions below.
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 hybrid system.
5. Raise the hood to warn other traffic, and to signal professional road assistance
personnel that you need assistance.
6. Have all passengers get out of the vehicle and stand in a safe place, away
from traffic and clear of the vehicle.
For the tire removing procedure, see “Jack-
ing up the vehicle and replacing tires” (P.8-
39).

Before attempting to jump start the vehicle,
make sure the fuel tank is not empty and the
correct starting procedure is followed. See
“Starting the INFINITI Direct Response
Hybrid
®System” (P.5-14). Do not drive the
vehicle on battery power only if the fuel tank
is empty. The Lithium ion (Li-ion) battery will
become discharged and the INFINITI Direct
Response Hybrid
®System will turn off.
CONFIRM BATTERY IS DIS-
CHARGED
If any of the following conditions occurs, the
12-volt battery might discharged:
. The instrument cluster and/or headlights
are not normal brightness.
. Audio accessories cannot be turned on.
. The hybrid system does not become
READY to drive mode.
. The ignition switch cannot be placed in
the ON position.
Check the following if you notice above
conditions.
1. Check that the 12-volt battery terminals are tight and clean. See “12-volt battery”
(P.8-14). The 12-volt battery is located
on the left hand side of the trunk behind
an access panel. If the 12-volt battery
terminals are loose, it is recommended
you contact an INFINITI retailer. 2. If the 12-volt battery terminals are tight
and clean, try to jump start the vehicle.
See “Jump starting” (P.6-5).
If the hybrid system still does not start, it is
recommended that you contact an INFINITI
retailer. To start your INFINITI Direct Response
Hybrid
®System with a booster battery, the
instructions and precautions below must be
followed.
Jump starting provides power to the 12 volt
system to allow the electrical systems to
operate. The electrical systems must be
operating to allow the Lithium ion (Li-ion)
battery to be charged. Jump starting does
not charge the Li-ion battery.
WARNING
. If done incorrectly, jump starting can
lead to a 12-volt 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 12-volt
battery. Make sure that the vent
tube is mounted.
. Do not allow battery fluid to come
into contact with eyes, skin, clothing
or painted surfaces. Battery fluid is a
corrosive sulfuric acid solution which
can cause severe burns. If the fluid
should come into contact with any-
thing, immediately flush the con-
tacted area with water.
. Keep the 12-volt battery out of the
reach of children.

IF THE VEHICLE DOES NOT STARTJUMP STARTING

6-6In case of emergency
.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 12-
volt battery, always wear suitable
eye protectors (for example, goggles
or industrial safety spectacles) and
remove rings, metal bands, or any
other jewelry. Do not lean over the
12-volt 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.
CAUTION
Do not attempt to jump start a hybrid
vehicle as a booster vehicle.JVE0174X
WARNING
Always follow the instructions below.
Failure to do so could result in damage to
the charging system and cause personal
injury. 1. If the booster battery is in another
vehicle
, position the two vehicles (and) to bring the battery and the fuse
box into close proximity to each other.
Do not allow the two vehicles to touch.
2. Apply parking brake. Move the shift lever to the P (Park) position. Switch off all

CAUTION
.Do not continue to drive if your
vehicle overheats. Doing so could
cause engine damage or a vehicle fire.
. To avoid the danger of being scalded,
never remove the radiator cap while
the engine is still hot. When the
radiator cap is removed, pressurized
hot water will spurt out, possibly
causing serious injury.
. Do not open the hood if steam is
coming out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading),
or if you feel a lack of engine power, detect
abnormal noise, etc., take the following
steps:
1. Move the vehicle safely off the road, apply the parking brake and move the
shift lever to the P (Park) position.
Do not turn the INFINITI Direct Re-
sponse Hybrid
®System off.
2. Turn off the climate control. Open all the windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed. 3. If engine overheating is caused by climb-
ing a long hill on a hot day, run the engine
at a fast idle (approximately 1,500 rpm)
until the temperature gauge indication
returns to normal.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from the
radiator before opening the hood. (If
steam or coolant is escaping, turn off the
hybrid system.) Do not open the hood
further until no steam or coolant can be
seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. Also check if the cooling fan is running. The radiator hoses and radiator should
not leak water. If coolant is leaking or the
cooling fan does not run, stop the hybrid
system.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, the engine cooling
fan. The engine cooling fan can start at
any time.
7. After the engine cools down, check the coolant level in the reservoir tank with
the engine running. Add coolant to the
reservoir tank if necessary. Have your
vehicle repaired. It is recommended you
visit an INFINITI retailer for this service.
