gency conditions. All turn signal lights flash.
WARNING
• If stopping for an emergency, be sure to
move the vehicle well off the road.
• Do not use the hazard warning flashers
while moving on the highway unless un-
usual circumstances force you to drive so
slowly that your vehicle might become a
hazard to other traffic.
• Turn signals do not work when the haz-
ard warning flasher lights are on. The flashers will operate with the ignition
switch placed in any position.
Some jurisdictions may prohibit the use of
the hazard warning flasher switch while
driving.
In the event of a roadside emergency, road-
side assistance service is available to you.

HAZARD WARNING FLASHER
SWITCH
ROADSIDE ASSISTANCE PROGRAM
6-2In case of emergency

To shut off the engine in an emergency situ-
ation while driving, perform the following
procedure:
– Rapidly push the push-button ignitionswitch three consecutive times in less than
1.5 seconds, or
– Push and hold the push-button ignition switch for more than 2 seconds.TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with Tire Pressure
Monitoring System (TPMS). It monitors tire
pressure of all tires. When the low tire pres-
sure warning light is lit, and the “Tire Pressure
Low - Add Air” or “Flat Tire-Visit dealer” (if so
equipped) warning appears in the vehicle in-
formation display, one or more of your tires is
significantly under-inflated. The system also
displays pressure of all tires (except the spare
tire) on the vehicle information display screen
by sending a signal from a sensor that is
installed in each wheel. 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 acti-
vate only when the vehicle is driven at speeds
above 16 mph (25 km/h). For additional in-
formation, see “Warning lights, indicator
lights and audible reminders” (P. 2-9) and
“Tire Pressure Monitoring System (TPMS)”
(P. 8-27).
WARNING
• Radio waves could adversely affect elec-
tric 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 illu-
minates 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 recom-
mended 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 or the TPMS may be
malfunctioning. If you have a flat tire,
replace it with a replacement tire as soon
as possible. If no tires are flat and all tires
are properly inflated, have the vehicle
checked. It is recommended that you
visit an INFINITI retailer for this service.
EMERGENCY ENGINE SHUT OFF FLAT TIRE
In case of emergency6-3

•When using a wheel without TPMS such
as the spare tire, the TPMS will not func-
tion and the low tire pressure warning
light will flash for approximately 1 min-
ute. The light will remain on after 1 min-
ute. Have your tires replaced and/or
TPMS system reset as soon as possible.
It is recommended that you visit an
INFINITI retailer for these services.
• 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
This vehicle is equipped with run-flat tires.
Run-flat tires can be used temporarily if they
are punctured. When the “Flat Tire — Visit
dealer” warning appears in the vehicle infor-
mation display, one or more of your tires is
punctured. For additional information, see
“Run-flat tires” (P. 8-36).
For additional information, refer to the tire
safety information in the Warranty Informa-
tion 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 per-
sonal 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 ap-
proximately 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, ve-
hicle 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 vi-
brations 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 dam-
aged and need to be replaced.CAUTION
• Never install tire chains on a punctured
run-flat tire, as this could damage your
vehicle.
• Avoid diving over any projection or pot-
hole, as the clearance between the ve-
hicle 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 re-
pair shop. Replace the tire as soon as
possible if the tire is seriously damaged.
6-4In case of emergency

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 dam-
age your vehicle.
• Explosive hydrogen gas is always pres-
ent 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 corro-
sive sulfuric acid solution which can
cause severe burns. If the fluid should
come into contact with anything, imme-
diately flush the contacted area with
water.
• Keep 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 remove 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 seri-
ous injury.
• Your vehicle has an automatic engine
cooling fan. It could come on at any time.
Keep hands and other objects away from
it.
JUMP STARTING
In case of emergency6-5

WARNING
Always follow the instructions below. Fail-
ure 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 to bring their
batteries near each other.
Do not allow the two vehicles to touch.
2. Apply the parking brake. Engage the P (Park) position. Switch off all unnecessary
electrical systems (lights, heater, air con-
ditioner, etc.). 3. Place the ignition switch to the LOCK or
OFF position.
4. Connect the jumper cables in the se- quence illustrated (
OA,OB,OC,OD).
CAUTION
• Always connect positive (+) to positive
(+) and negative (−) to body ground (for
example, strut mounting bolt, engine lift
bracket, etc.) — not to the battery.
• Make sure the jumper cables do not
touch moving parts in the engine com-
partment and that the cable clamps do
not contact any other metal. 5. Start the engine of the booster vehicle and
let it run for a few minutes.
6. Keep the engine speed of the booster ve- hicle at about 2,000 rpm and start the
engine of the vehicle being jump started.
CAUTION
Do not keep the starter motor engaged for
more than 10 seconds. If the engine does
not start right away, place the ignition
switch in the OFF position and wait 3 to 4
seconds before trying again.
7. After starting the engine, carefully discon- nect the negative cable and then the posi-
tive cable.

CAUTION
• Continuously Variable Transmission
(CVT) models cannot be push-started or
tow-started. Attempting to do so may
cause transmission damage.
• Do not push start this vehicle. The three-
way catalyst may be damaged.WARNING
• 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 coolant reservoir cap
while the engine is still hot. When the
coolant reservoir cap is removed, pres-
surized 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 engage the P (Park)
position.
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed. 3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radia-
tor before opening the hood. (If steam or
coolant is escaping, turn off the engine.)
Do not open the hood further until no
steam or coolant can be seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine, stand clear to prevent getting
burned.
5. Visually check drive belts for damage or looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leaking,
the water pump belt is missing or loose, or
the cooling fan does not run, stop the
engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling fan
can start at any time.
PUSH STARTING IF YOUR VEHICLE OVERHEATS
In case of emergency6-7

6. After the engine cools down, check thecoolant level in the engine coolant reser-
voir tank with the engine running. Add
coolant to the engine coolant reservoir
tank if necessary. Have your vehicle re-
paired. It is recommended that you visit an
INFINITI retailer for this service. When towing your vehicle, all jurisdictions
and local regulations for towing must be fol-
lowed. Incorrect towing equipment could
damage your vehicle. Towing instructions are
available from an INFINITI retailer. Local ser-
vice operators are generally familiar with the
applicable laws and procedures for towing.
To assure proper towing and to prevent ac-
cidental damage to your vehicle, INFINITI
recommends having a service operator tow
your vehicle. It is advisable to have the service
operator carefully read the following
precautions:
WARNING
• Never ride in a vehicle that is being
towed.
• Never get under your vehicle after it has
been lifted by a tow truck.
CAUTION
• When towing, make sure that the trans-
mission, axles, steering system and pow-
ertrain are in working condition. Use dol-
lies or flatbed if any of the listed systems
are not working.
• Always attach safety chains before
towing. For additional information about towing your
vehicle behind a Recreational Vehicle (RV),
see “Flat towing for all wheel drive vehicle”
