2014 INFINITI QX60 HYBRID overheating

WARNING
Your brake system may not be working
properly if the hydraulic brake warning
light and the electronically controlled
brake system warning light is on. Driving
could be dangerous. If you judge it to be
safe, drive carefully to the nearest service
station for repairs. Otherwise, have your
vehicle towed because driving it could be
dangerous.
BRAKE PRECAUTIONS
Vacuum-assisted brakes
The brake booster aids braking by using engine
vacuum. If the hybrid system is turned off, you can
stop the vehicle by depressing the brake pedal.
However, greater foot pressure on the brake
pedal will be required to stop the vehicle and
stopping distance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out the
brake pads faster, and reduce gas mileage.To help reduce brake wear 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.
When applying the brakes, you may hear a sound
coming from the braking system. This is normal.
WARNING
While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or acceler-
ating could cause the wheels to skid and
result in an accident.

CAUTION
If the green READY light does not come
on, press the START button to turn the
hybrid system OFF. Carefully disconnect
the negative cable then the positive cable.
Have vehicle taken to dealership for
repair.9. After the green READY light in the meter display comes ON, carefully disconnect the
negative cable and then the positive cable.
10. Replace the vent caps (if so equipped) . Be sure to dispose of the cloth used to cover
the vent holes as it may be contaminated
with corrosive acid.
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 radiator or coolant
reservoir cap while the engine is still
hot. When the radiator or coolant reser-
voir cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
● Do not open the hood if steam is com-
ing out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading and
the illumination of the engine oil pressure/engine
coolant temperature high indicator light) , 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
P (Park) .
Do not turn the INFINITI Direct Re-
sponse Hybrid® System off. 2. Turn off the air conditioner. Open all the
windows, move the heater or air conditioner
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 radiator
before opening the hood. (If steam or cool-
ant 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. Also check if the cooling fan is running. The radiator hoses and radiator should not leak
water. If the coolant is leaking or the cooling
fan does not run, stop the hybrid system.
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 coolant is leaking,
the water pump belt is missing or loose, or
the cooling fan does not run, stop the en-
gine.

CHECKING INVERTER COOLANT
LEVEL
Check the coolant levelin the reservoir when
the engine and inverter are cold. The coolant
level should be between the MIN level
B, add
coolant to the MAX level
A.
If the inverter cooling system frequently
requires coolant, have it checked by a
INFINITI retailer.
CHANGING INVERTER COOLANT
Major cooling system repairs should be done by a
INFINITI retailer. The service procedure can be
found in the INFINITI Service Manual.
Improper servicing can result in inverter
overheating.
WARNING
● To avoid the danger of being scalded,
never change the coolant when the in-
verter is hot.
● Never remove the cap when the inverter
is hot. Serious burns could be caused by
high pressure fluid escaping from the
inverter coolant reservoir.
● Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner as
soon as possible.
● Keep coolant out of the reach of chil-
dren and pets.
Engine coolant must be disposed of properly.
Check your local regulations.
CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and apply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature.
3. Turn off the engine. Wait more than
10 minutes for the oil to drain back into
the oil pan.
4. Remove the dipstick and wipe it clean. Re- insert it all the way.

– On roads where the traffic is heavy or
there are sharp curves
– On slippery road surfaces such as on
ice or snow, etc.
– During bad weather (rain, fog, snow,
etc.)
– When rain, snow or dirt adhere to the
bumper around the distance sensor
– On steep downhill roads (the vehicle
may go beyond the set vehicle speed
and frequent braking may result in
overheating the brakes)
– On repeated uphill and downhill
roads
– When traffic conditions make it diffi-
cult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration
●Do not use the Intelligent Cruise Con-
trol system if you are towing a trailer.
The system may not detect a vehicle
ahead.●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. Al-
ways 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 ve-
hicle and be ready to manually control the proper
following distance. The vehicle-to-vehicle dis-
tance control mode of the Intelligent Cruise Con-
trol (ICC) system may not be able to maintain the
selected distance between vehicles (following
distance) or selected vehicle speed under some
circumstances.
The vehicle-to-vehicle distance control mode
uses a sensor
Alocated behind the front bum-
per of the vehicle to detect vehicles traveling
ahead. The sensor generally detects the signals
LSD2098
5-56Starting and driving

The detection range of the sensor is approxi-
mately 490 ft (150 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 re-
sponsibility to stay alert, drive safely
and be in control of the vehicle at all
times.
●This system will not adapt automatically
to road conditions.
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. Deceler-
ate 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 detect the vehicle
in front of you in certain road or weather
conditions. To avoid accidents, never
use the Distance Control Assist system
under the following conditions:
– On roads with sharp curves
– On slippery road surfaces such as on
ice or snow, etc.
– During bad weather (rain, fog, snow,
etc.)
– When rain, snow or dirt adhere to the
sensor area of the front bumper– On steep downhill roads (frequent
braking may result in overheating the
brakes)
– On repeated uphill and downhill
roads
●Do not use the Distance Control Assist
system if you are towing a trailer. The
system may not detect a vehicle ahead.
●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. Al-
ways stay alert and avoid using the DCA
system when it is not recommended in
this section.

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.
●When the power steering warning light
illuminates with the engine running,
there will be no power assist for the
steering. You will still have control of
the vehicle but the steering will be
harder to operate. Have the power
steering system checked by an INFINITI
retailer.
The power steering system is designed to pro-
vide power assist while driving to operate the
steering wheel with light force.
When the steering wheel is operated repeatedly
or continuously while parking or driving at a very
low speed, the power assist for the steering
wheel will be reduced. This is to prevent over-
heating of the power steering system and protect
it from getting damaged. While the power assist
is reduced, steering wheel operation will become
heavy. If the steering wheel operation is still per-
formed, the power steering may stop and the
power steering warning light will illuminate. In a
safe location, stop the engine and push the igni-
tion switch to the OFF position. The temperatureof the power steering system will go down after a
period of time and the power assist level will
return to normal after starting the engine. The
power steering warning light will go off. Avoid
repeating such steering wheel operations that
could cause the power steering system to over-
heat.
You may hear a sound from the front of the vehicle
when the steering wheel is operated quickly. This
is a normal operational noise and is not a mal-
function.
If the electric power steering warning lightPS
illuminates while the engine is running, it may
indicate the power steering system is not func-
tioning properly and may need servicing. Have
the power steering system checked by an
INFINITI retailer.
When the electric power steering warning light
illuminates with the engine running, there will be
no power assist for the steering but you will still
have control of the vehicle. At this time, greater
steering effort is required to operate the steering
wheel, especially in sharp turns and at low
speeds.
For additional information see “Power steering
warning light” in the “Instruments and controls”
section.The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at 2 wheels.
