2014 INFINITI QX80 heating

WARNING
.The air conditioner cooling function
operates only when the engine is run-
ning.
. Do not leave children or adults who
would normally require the support of
others alone in your vehicle. Pets should
not be left alone either. On hot, sunny
days, temperatures in a closed vehicle
could quickly become high enough to
cause severe or possibly fatal injuries to
people or animals.
. Do not use the recirculation mode for
long periods as it may cause the interior
air to become stale and the windows to
fog up.
. Do not adjust the heating and air
conditioning controls while driving so
that full attention may be given to
vehicle operation.
Start the engine and operate the automatic
climate control system.

ENGINE PROTECTION MODE
The engine has an engine protection mode
to reduce the chance of damage if the
coolant temperature becomes too high (for
example, when climbing steep grades in
high temperature with heavy loads, such
as when towing a trailer).
When the engine temperature reaches a
certain level:
.The engine coolant temperature gauge
will move toward the H position.
. Engine power may be reduced.
. The air conditioning cooling function
may be automatically turned OFF for a
short time (the blower will continue to
operate).
Engine power and, under some conditions,
vehicle speed will decrease. Vehicle speed
can be controlled with the accelerator
pedal, but the vehicle may not accelerate
at the desired speed. The transmission will
downshift or upshift as it reaches pre-
scribed shift points. You can also shift
manually.
As driving conditions change and engine
coolant temperature is reduced, vehicle
speed can be increased using the accel-
erator pedal, and air conditioning cooling function will automatically be turned back
ON.
If:
1. The engine coolant temperature is not
reduced.
2. The air conditioning cooling function does not turn back ON.
3. The engine oil pressure warning light
illuminates or engine coolant
temperature gauge does not return to
the normal range from the H position,
this may indicate a malfunction. Move
the vehicle off the road to a safe area
and allow the engine to cool. If after
checking the oil and coolant, the
remains on or engine coolant tempera-
ture does not return to the normal
range, do not continue to drive and
contact an INFINITI retailer.
The Malfunction Indicator Light (MIL)
may also come ON. You do not need to
have your vehicle towed, unless it remains
on, but have it inspected soon by an
INFINITI retailer. See “Warning/indicator
lights and audible reminders” in the“2.
Instruments and controls” section.
WARNING
Overheating can result in reduced engine
power and vehicle speed. The reduced speed
may be lower than other traffic, which could
increase the chance of a collision. Be
especially careful when driving. If the
vehicle cannot maintain a safe driving
speed, pull to the side of the road in a safe
area. Allow the engine to cool and return to
normal operation. See“If your vehicle over-
heats” in the“6. In case of emergency”
section.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Such damage is not covered
by warranty. Turn off the engine as soon as
it is safe to do so.
DRIVING THE VEHICLE

under the following conditions. To avoid
accidents, never use the ICC system
under the following conditions:
—On roads where the traffic is heavyor there are sharp curves
—On slippery road surfaces such as
on ice or snow, etc.
—On off-road surfaces such as onsand or rock, etc.
—During bad weather (rain, fog, snow,
etc.)
—When the windshield wipers areoperating at high speed. The system
may cancel when the wipers are set
to the AUTO position.
—When strong light (for example, at sunrise or sunset) is directly shining
on the front of the vehicle
—When rain, snow or dirt adhere tothe system sensor
—On steep downhill roads (the vehi-cle may go beyond the set vehicle
speed and frequent braking may
result in overheating the brakes)
—On repeated uphill and downhillroads
—When traffic conditions make itdifficult to keep a proper distance
between vehicles because of fre-
quent acceleration or deceleration
—When towing a trailer or othervehicle
. In some road or traffic conditions, a
vehicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. You may need to
control the distance from other vehicles
using the accelerator pedal. Always stay
alert and avoid using the ICC system
when it is not recommended in this
section.

VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE OPERATION
Always pay attention to the operation of
the vehicle and be ready to manually
control the proper following distance. The
vehicle-to-vehicle distance control mode of
the Intelligent Cruise Control (ICC) system
may not be able to maintain the selected
distance between vehicles (following dis-
tance) or selected vehicle speed under
some circumstances.
The vehicle-to-vehicle distance control
mode uses a sensor
*Alocated on the
front of the vehicle to detect vehicles
Starting and driving5-59

The detection range of the sensor is
approximately 390 ft (120 m) ahead.
WARNING
.This system is only an aid to assist the
driver and is not a collision warning or
avoidance device. It is the driver’ s
responsibility to stay alert, drive safely
and be in control of the vehicle at all
times.
. This system will not adapt automatically
to road conditions. Do not use the
system on roads with sharp curves, or
on icy roads, in heavy rain or in fog.
The distance sensor will not detect the
following objects:
.Stationary and slow moving vehicles
. Pedestrians or objects in the roadway
. Oncoming vehicles in the same lane
. Motorcycles traveling offset in the travel
lane
WARNING
. As there is a performance limit to the
distance control function, never rely
solely on the Distance Control Assist
system. This system does not correct
careless, inattentive or absent-minded
driving, or overcome poor visibility in
rain, fog, or other bad weather. Decele-
rate the vehicle speed by depressing the
brake pedal, depending on the distance
to the vehicle ahead and the surround-
ing circumstances in order to maintain a
safe distance between vehicles.
. The system may not function properly
under the following conditions. To avoid
accidents, never use the Distance Con-
trol Assist system under the following
conditions:
—On roads with sharp curves
—On slippery road surfaces such as
on ice or snow, etc.
—On off-road surfaces such as onsand or rock, etc.
—During bad weather (rain, fog, snow,etc.)
—When strong light (for example, atsunrise or sunset) is directly shining
on the front of the vehicle
—When rain, snow or dirt adhere tothe system sensor
—On steep downhill roads (frequent
braking may result in overheating
the brakes)
—On repeated uphill and downhillroads
—When towing a trailer or othervehicle
. In some road or traffic conditions, a
vehicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. You may need to
control the distance from other vehicles
using the accelerator pedal. Always stay
alert and avoid using the DCA system
when it is not recommended in this
section.
Starting and driving5-79

5-110Starting and driving
WARNING
If the engine is not running or is turned off
while driving, the power assist for the
steering will not work. Steering will be
harder to operate.
The power assisted steering uses a hy-
draulic pump, driven by the engine, to
assist steering.
If the engine stops or the drive belt breaks,
you will still have control of the vehicle.
However, much greater steering effort is
needed, especially in sharp turns and at
low speeds.
BRAKING PRECAUTIONS
The brake system has two separate hy-
draulic circuits. If one circuit malfunctions,
you will still have braking ability at two
wheels.
You may feel a small click and hear a sound
when the brake pedal is fully depressed
slowly. This is not a malfunction and
indicates that the brake assist mechanism
is operating properly.
Hydraulically-assisted brakes
The hydraulically-assisted brake system is
designed to use a hydraulic pump driven
electrically, to assist braking. If the engine
stops, you can stop the vehicle by depres-
sing the foot brake pedal. However, greater
foot pressure on the foot brake pedal will
be required to stop the vehicle. The
stopping distance will be longer.
Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet.
As a result, your braking distance will be
longer and the vehicle may pull to one side
during braking.
To dry brakes, drive the vehicle at a safe
speed while lightly tapping the brake pedalto heat-up the brakes. Do this until the
brakes return to normal. Avoid driving the
vehicle at high speeds until the brakes
function correctly.
PARKING BRAKE BREAK-IN
Break in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or drums/rotors are replaced,
in order to assure the best braking
performance.
This procedure is described in the vehicle
service manual and can be performed by
an INFINITI retailer.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will cause overheating
of the brakes, wearing out the brake and
pads faster and reduce gas mileage.
To help save the brakes and to prevent the
brakes from overheating, reduce speed
and downshift to a lower gear before going
down a slope or long grade. Overheated
brakes may reduce braking performance
and could result in loss of vehicle control.

6-14In case of emergency
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 or coolant
reservoir cap while the engine is still
hot. When the radiator cap or coolant
reservoir cap is removed, pressurized
hot water will spurt out, possibly caus-
ing 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 stop the engine.
2. Turn off the climate control. Open all the windows, move the heater or air
conditioner temperature control to 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 engine.) 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. 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 cool-
ant is leaking 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.
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.
