2014 INFINITI Q50 warning lights

5-86Starting and driving
When a vehicle ahead is detected:
The vehicle ahead detection indicator
comes on.
When the vehicle approaches a vehicle
ahead:
.If the driver’ s foot is not on the
accelerator pedal, the system activates
the brakes to decelerate smoothly as
necessary. If the vehicle ahead comes
to a stop, the vehicle decelerates to a
standstill within the limitations of the
system.
. If the driver’s foot is on the accelerator
pedal, the system moves the accelera-
tor pedal upward to assist the driver to
release the accelerator pedal.
When brake operation by the driver is
required:
The system alerts the driver by a warning
chime and blinking the vehicle ahead
detection indicator. If the driver’s foot is
on the accelerator pedal after the warning,
the system moves the accelerator pedal
upward to assist the driver to switch to the
brake pedal. The stop lights of the vehicle come on
when braking is performed by the DCA
system.
When the brake operates, a noise may be
heard. This is not a malfunction.
WARNING
.
When the vehicle ahead detection in-
dicator is not illuminated, the system
will not control or warn the driver.
. Depending on the position of the accel-
erator pedal, the system may not be able
to assist the driver to release the
accelerator pedal appropriately.
. If the vehicle ahead comes to a stand-
still, the vehicle decelerates to a stand-
still within the limitations of the system.
The system will release brake control
with a warning chime once it judges the
vehicle is at a standstill. To prevent the
vehicle from moving, the driver must
depress the brake pedal. (The system
will resume control automatically once
the system reaches 3 MPH (5 km/h)).
Overriding the system:
The following driver’s operation overrides
the system operation.
.When the driver depresses the accel-
erator pedal even further while the
system is moving the accelerator pedal
upward, the DCA system control of the
accelerator pedal is canceled.
. When the driver’s foot is on the accel-
erator pedal, the brake control by the
system is not operated.
. When the driver’s foot is on the brake
pedal, neither the brake control nor the
alert by the system operates.
. When the Intelligent Cruise Control (ICC)
system is set, the DCA system will be
cancelled.
Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that
vehicle or if another vehicle cuts in, the
system warns the driver with the chime
and DCA system display. Decelerate by
depressing the brake pedal to maintain a
safe vehicle distance if:
. The chime sounds.
. The vehicle ahead detection indicator
blinks.

1. Driver assist system forward indicator
2. Vehicle ahead detection indicator
SYSTEM OPERATION
The forward emergency braking system will
function when your vehicle is driven at
speeds above approximately 3 MPH (5
km/h).
If a risk of a forward collision is detected,
the forward emergency braking system will
provide the first warning to the driver by
flashing the driver assist system forward
indicator (orange) and the vehicle ahead
detection indicator (orange), and providing
an audible warning. In addition, theforward emergency braking system pushes
the accelerator pedal up. If the driver
releases the accelerator pedal, then the
system applies partial braking.
If the driver applies the brakes quickly and
forcefully after the warning, and the
forward emergency braking system detects
that there is still the possibility of a
forward collision, the system will automa-
tically increase the braking force.
If a forward collision is imminent and the
driver does not take action, the forward
emergency braking system issues the
second visual (red) and audible warning
and automatically applies harder braking.NOTE:
The vehicle’s stop lights come on when
braking is performed by the forward
emergency braking system.
Depending on vehicle speed and distance
to the vehicle ahead, as well as driving and
roadway conditions, the system may help
the driver avoid a forward collision or may
help mitigate the consequences if a colli-
sion should one be unavoidable.
If the driver is handling the steering wheel,
accelerating or braking, the forward emer-
gency braking system will function later or
will not function.
The automatic braking will cease under the
following conditions:
.
When the steering wheel is turned as
far as necessary to avoid a collision.
. When the accelerator pedal is de-
pressed.
. When there is no longer a vehicle
detected ahead.
If the forward emergency braking system
has stopped the vehicle, the vehicle will
remain at a standstill for approximately 2
seconds before the brakes are released.

6-2In case of emergency
SIC2574
Push the switch on to warn other drivers
when you must stop or park under
emergency conditions. All turn signal lights
will 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
unusual circumstances force you to drive
so slowly that your vehicle might be-
come a hazard to other traffic. .
Turn signals do not work when the
hazard warning flasher lights are on.
The flasher can be actuated with the
ignition switch in any position.
Some state laws may prohibit the use of
the hazard warning flasher switch while
driving. In the event of a roadside emergency,
Roadside Assistance Service is available to
you. Please refer to your Warranty Informa-
tion Booklet (U.S.) or Warranty & Roadside
Assistance Information Booklet (Canada)
for details.
HAZARD WARNING FLASHER SWITCH
ROADSIDE ASSISTANCE PROGRAM

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.TIRE PRESSURE MONITORING SYS-
TEM (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. 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/indicator lights and audible re-
minders” (P.2-12) and “Tire Pressure Mon-
itoring System (TPMS)” (P.5-4).
WARNING
.Radio waves could adversely affect
electric 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
illuminates 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
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).
. 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

seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and that all
latches lock securely in every position.
Check that the head restraints move up
and down smoothly and that the locks (if
so equipped) hold securely in all latched
positions.
Steering wheel:Check for changes in the
steering conditions, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure that
all warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check that
the wipers and washer operate properly
and that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (for example, each
time you check the engine oil or refuel).
Battery*: Check the fluid level in each cell.
It should be between the MAX and MIN
lines. Vehicles operated in high tempera- tures or under severe condition require
frequent checks of the battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1.
Installation or extended use of electro-
nic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
Brake fluid level*: Make sure that the
brake fluid level is between the MAX and
MIN lines on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure that no belt
is frayed, worn, cracked or oily.
Engine oil level*: Check the level after
parking the vehicle on a level spot and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the oil pan.
Exhaust system:
Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, im-
mediately have the exhaust system in-
spected by an INFINITI retailer. (See
“Precautions when starting and driving”
(P.5-3).)
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use
is normal. If you should notice any leaks or
if gasoline fumes are evident, check for the
cause and have it corrected immediately.
Power steering fluid level* and lines:
Check the level when the fluid is cold,
with the engine off. Check the lines for
proper attachment, leaks, cracks, etc.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks,
deformation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust.
