check engine INFINITI QX60 2018 Workshop Manual

WARNING
∙ If the engine is not running or is turned offwhile 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. It is recommended that you visit
an INFINITI retailer for this service.
The power steering system is designed to
provide power assist while driving to operate
the steering wheel with light force.
When the steering wheel is operated repeat-
edly or continuously while parking or driving
at a very low speed, the power assist for the
steering wheel will be reduced. This is to pre-
vent overheating of the power steering sys-
tem and protect it from getting damaged.
While the power assist is reduced, steering
wheel operation will become heavy. When
the temperature of the power steering sys-
tem goes down, the power assist level will
return to normal. Avoid repeating such steer-
ing wheel operations that could cause the
power steering system to overheat. You may hear a sound when the steering
wheel is operated quickly. However, this is
not a malfunction.
If the power steering warning light illumi-
nates while the engine is running, it may indi-
cate the power steering system is not func-
tioning properly and may need servicing.
Have the power steering system checked. It is
recommended that you visit an INFINITI re-
tailer for this service.
When the power steering warning light illu-
minates 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, refer to “Power
steering warning light” in the “Instruments
and controls” section of this manual.
The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will
still have braking at two wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using en-
gine vacuum. If the engine stops, you can
stop the vehicle by depressing the brake
pedal. However, greater foot pressure on the
brake pedal will be required to stop the ve-
hicle 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.
POWER STEERING
BRAKE SYSTEM
5-134Starting and driving

WARNING
Do not pump the brake pedal. Doing so may
result in increased stopping distances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer.
The computer has a built-in diagnostic fea-
ture that tests the system each time you start
the engine and move the vehicle at a low
speed in forward or reverse. When the self-
test occurs, you may hear a “clunk” noise
and/or feel a pulsation in the brake pedal.
This is normal and does not indicate a mal-
function. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates
the ABS warning light on the instrument
panel. The brake system then operates nor-
mally but without anti-lock assistance.
If the ABS warning light illuminates during
the self-test or while driving, have the vehicle
checked. It is recommended that you visit an
INFINITI retailer for this service.
Normal operation
The Anti-lock Braking System (ABS) operates
at speeds above3-6mph(5-10km/h). The
speed varies according to road conditions. When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsation
in the brake pedal and hear a noise from
under the hood or feel a vibration from the
actuator when it is operating. This is normal
and indicates that the ABS is operating prop-
erly. However, the pulsation may indicate
that road conditions are hazardous and extra
care is required while driving.
BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the brake assist is
activated generating greater braking force
than a conventional brake booster even with
light pedal force.
WARNING
The brake assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the driv-
er’s responsibility to stay alert, drive safely
and be in control of the vehicle at all times.
The VDC system uses various sensors to
monitor driver inputs and vehicle motion. Un-
der certain driving conditions, the VDC sys-
tem helps to perform the following functions:
∙ Controls brake pressure to reduce wheel slip on one slipping drive wheel so power
is transferred to a non-slipping drive
wheel on the same axle.
∙ Controls brake pressure and engine out- put to reduce drive wheel slip based on
vehicle speed (traction control function).
∙ Controls brake pressure at individual wheels and engine output to help the
driver maintain control of the vehicle in
the following conditions:
– Understeer (vehicle tends to not fol- low the steered path despite in-
creased steering input)
– Oversteer (vehicle tends to spin due to certain road or driving conditions)
The VDC system can help the driver to main-
tain control of the vehicle, but it cannot pre-
vent loss of vehicle control in all driving situ-
ations.
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
5-136Starting and driving

Do not attach stickers (including transparent
material), install accessories or apply addi-
tional paint near the sonar sensors.
Do not strike or damage the area around the
sonar sensors. It is recommended that you
visit an INFINITI retailer if the area around
the sonar sensors is damaged due to a colli-
sion.FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
de-icer through the key hole. If the lock be-
comes frozen, heat the key before inserting it
into the key hole, or use the INFINITI Intelli-
gent Key.
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper winter
protection. For additional information, refer
to “Engine cooling system” in the “Do-it-
yourself” section of this manual.
BATTERY
If the battery is not fully charged during ex-
tremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery
should be checked regularly. For additional
information, refer to “Battery” in the “Do-it-
yourself” section of this manual.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
anti-freeze, drain the cooling system, includ-
ing the engine block. Refill before operating
the vehicle. For additional information, refer
to “Changing engine coolant” in the “Do-it-
yourself” section of this manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced
in snowy and icy conditions. If you oper-
ate your vehicle on snowy or icy roads,
INFINITI recommends the use of MUD &
SNOW or ALL SEASON TIRES on all
four wheels. It is recommended that you
visit an INFINITI retailer for the tire type,
size, speed rating and availability infor-
mation.
2. For additional traction on icy roads, studded tires may be used. However,
some U.S. states and Canadian prov-
inces prohibit their use. Check local,
state and provincial laws before install-
ing studded tires.
COLD WEATHER DRIVING
5-144Starting and driving

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 TPMS. It moni-
tors tire pressure of all tires except the spare.
When the low tire pressure warning light is lit,
and the “Tire Pressure Low - Add Air” warn-
ing appears in the vehicle information display,
one or more of your tires is significantly
under-inflated. If equipped, the system also
displays pressure of all tires (except the spare
tire) on the display screen by sending a signal
from a sensor that is installed in each wheel. If
the vehicle is being driven with low tire pres-
sure, 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 additional information, refer to “Warning
lights, indicator lights and audible reminders”
in the “Instruments and controls” section and
the “Tire Pressure Monitoring System
(TPMS)” in the “Starting and driving” sections
of this manual.
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 you have a flat tire, replace it with
a spare tire as soon as possible.

CAUTION
∙ CVT models cannot be push-started ortow-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 vehicleoverheats. Doing so could cause engine
damage or a vehicle fire.
∙
To avoid the danger of being scalded,
never remove the radiator or coolant res-
ervoir cap while the engine is still hot.
When the radiator or coolant reservoir 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 P (Park).
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 ra-
diator 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 engine,
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 leak-
ing, 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.
6. After the engine cools down, check the coolant 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.

CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir when
the engine is cold. If the coolant level is below
the MIN level
B, add coolant to the MAX
level
A. If the reservoir is empty, check the
coolant level in the radiator when the engine
is cold. If there is insufficient coolant in the
radiator, fill the radiator with coolant up to
the filler opening and also add it to the reser-
voir up to the MAX level
A. This vehicle contains Genuine NISSAN Long
Life Antifreeze/Coolant (blue). The life ex-
pectancy of the factory-fill coolant is
105,000 miles (168,000 km) or 7 years.
Mixing any other type of coolant or the use of
non-distilled water will reduce the life expec-
tancy of the factory-fill coolant. For addi-
tional information, refer to the "Maintenance
and schedules" section of this manual.
If the cooling system frequently requires
coolant, have it checked. It is recommended
that you visit an INFINITI retailer for this
service.
For additional information on the location of
the engine coolant reservoir, refer to “Engine
compartment check locations” in this section.
CHANGING ENGINE COOLANT
An INFINITI retailer can change the engine
coolant. The service procedure can be found
in the INFINITI Service Manual.
Improper servicing can result in reduced
heater performance and engine overheating.
WARNING
∙ To avoid the danger of being scalded,
never change the coolant when the en-
gine is hot.
∙ Never remove the radiator or engine coolant reservoir cap when the engine is
hot. Serious burns could be caused by
high pressure fluid escaping from the
radiator.
∙ Avoid direct skin contact with used cool- ant. If skin contact is made, wash thor-
oughly with soap or hand cleaner as soon
as possible.
∙ Keep coolant out of the reach of children 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 andapply 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. Reinsert it all the way. 5. Remove the dipstick again and check the
oil level. It should be between the H
(High) and L (Low) marksB. This is the
normal operating oil level range. If the oil
level is below the L (Low) mark
A, re-
move the oil filler cap and pour recom-
mended oil through the opening. Do not
fill oil level above H (High) mark
C.
6. Recheck the oil level with the dipstick.
It is normal to add some oil between oil main-
tenance intervals or during the break-in pe-
riod, depending on the severity of operating
conditions.
CAUTION
Oil level should be checked regularly. Oper-
ating the engine with an insufficient
amount of oil can damage the engine, and
such damage is not covered by warranty.
