2014 INFINITI Q50 HYBRID Owner's Manual

6-4In case of emergency
.Replacing tires with those not originally
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 pressure
sensors.
RUN-FLAT TIRES
Run-flat tires are those tires that can be
used temporarily if they are punctured. See
“Run-flat tires” (P.8-36).
Also, refer to “Important Tire Safety In-
formation” (US) or“Tire Safety Informa-
tion” (Canada) in the INFINITI Warranty
Information Booklet.
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 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 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.CAUTION
.Never install tire chains on a punctured
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.
. 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 assis-
tance personnel that you need assis-
tance.
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
“Jacking up the vehicle and replacing tires”
(P.8-40).

Before attempting to jump start the vehi-
cle, 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
®Sys-
tem will turn off.
CONFIRM BATTERY IS DISCHARGED
If any of the following conditions occurs,
the 12-volt battery might discharged:
. The instrument cluster and/or head-
lights 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.8-17). 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, contact your 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,
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 pre-
sent 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 anything,
immediately flush the contacted area
with water.

6-6In case of emergency
.Keep the 12-volt 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 12-volt
battery, always wear suitable eye pro-
tectors (for example, goggles or indus-
trial 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.

NOTE:
If it is not possible to turn the hybrid
system ON by following this procedure,
contact an INFINITI retailer immediately. Do not attempt to start the engine by
pushing.
CAUTION
.
Automatic Transmission (AT) models
cannot be push-started or tow-started.
Attempting to do so may cause trans-
mission damage.
. Three-way catalyst equipped models
should not be started by pushing since
the three-way catalyst may be damaged.
. Never try to start the vehicle by towing
it; when the engine starts, the forward
surge could cause the vehicle to collide
with the tow vehicle.
. Hybrid models cannot be push-started or
tow-started. Attempting to do so may
cause electrical or transmission damage.
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

maximum hot and fan control to high
speed.
3. If engine overheating is caused by climbing 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 thecoolant level in the reservoir tank with
the engine running. Add coolant to the
reservoir tank if necessary. Have your
vehicle repaired at the nearest INFINITI
retailer. When towing your vehicle, all State (Pro-
vincial in Canada) and local regulations for
towing must be followed. Incorrect towing
equipment could damage your vehicle.
Towing instructions are available from an
INFINITI retailer. Local service operators are
familiar with the applicable laws and
procedures for towing. To assure proper
towing and to prevent accidental damage
to your vehicle, INFINITI recommends that
you have a service operator tow your
vehicle. It is advisable to have the service
operator carefully read the following pre-
cautions.
