engine overheat INFINITI QX60 2017 User Guide

The engine cooling system is filled at the factory
with a pre-diluted mixture of 50% Genuine
NISSAN Long Life Antifreeze/Coolant (blue) and
50% water to provide year-round antifreeze and
coolant protection. The antifreeze solution con-
tains rust and corrosion inhibitors. Additional en-
gine cooling system additives are not necessary.
WARNING
●Never remove the radiator or coolant
reservoir cap when the engine is hot.
Wait until the engine and radiator cool
down. Serious burns could be caused
by high pressure fluid escaping from
the radiator. For additional information
on precautions, refer to “If your vehicle
overheats” found in the “In case of
emergency” section of this manual.
● The radiator is equipped with a pres-
sure type radiator cap. To prevent en-
gine damage, use only a Genuine
NISSAN radiator cap.
CAUTION
●Never use any cooling system additives
such as radiator sealer. Additives may
clog the cooling system and cause dam-
age to the engine, transmission and/or
cooling system.
● When adding or replacing coolant, be
sure to use only Genuine NISSAN Long
Life Antifreeze/Coolant (blue) or
equivalent. Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is pre-diluted
to provide antifreeze protection to
-34° F (-37° C) . If additional freeze pro-
tection is needed due to weather where
you operate your vehicle, add Genuine
NISSAN Long Life Antifreeze/Coolant
(blue) concentrate following the direc-
tions on the container. If an equivalent
coolant other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue) is
used, follow the coolant manufacturer’s
instructions to maintain minimum anti-
freeze protection to -34° F (-37° C) . The
use of other types of coolant solutions
other than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent
may damage the engine cooling
system. ●
The life expectancy of the factory-fill
coolant is 105,000 miles (168,000 km) or
7 years. Mixing any other type of cool-
ant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue) , includ-
ing Genuine NISSAN Long Life
Antifreeze/Coolant (green) , or the use
of non-distilled water will reduce the
life expectancy of the factory-fill cool-
ant. For additional information, refer to
the Maintenance and schedules section
of this manual.

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 reservoir up to the MAX level
A.
This vehicle contains Genuine NISSAN Long Life
Antifreeze/Coolant (blue) . The life expectancy 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 re-
duce the life expectancy of the factory-fill coolant.
For additional information, refer to the
Mainte-
nance and schedules section of this manual.
If the cooling system frequently requires
coolant, have it checked. It is recom-
mended that you visit an INFINITI retailer
for this service.
For additional information on the location of the
engine coolant reservoir, refer to “Engine com-
partment check locations” in this section.
CHANGING ENGINE COOLANT
An INFINITI retailer can change the engine cool-
ant. The service procedure can be found in the
INFINITI Service Manual.
Improper servicing can result in reduced
heater performance and engine overheat-
ing.
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
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.

Incorrect ignition timing may result in spark
knock, after-run and/or overheating, which may
cause excessive fuel consumption or engine
damage. If any of the above symptoms are en-
countered, have your vehicle checked. It is rec-
ommended that you visit an INFINITI retailer.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is not a
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.
ENGINE OIL AND OIL FILTER
RECOMMENDATIONS
Selecting the correct oil
It is essential to choose the correct grade, quality
and viscosity engine oil to ensure satisfactory
engine life and performance. For additional infor-
mation, refer toRecommended fluids/lubricants
and capacities in this section. INFINITI recom-
mends the use of an energy conserving oil in
order to improve fuel economy.
Select only engine oils that meet the American
Petroleum Institute (API) certification or Interna-
tional Lubricant Standardization and Approval Committee (ILSAC) certification and SAE vis-
cosity standard. These oils have the API certifica-
tion mark on the front of the container. Oils which
do not have the specified quality label should not
be used as they could cause engine damage.Oil additives
INFINITI does not recommend the use of oil ad-
ditives. The use of an oil additive is not necessary
when the proper oil type is used and maintenance
intervals are followed.
Oil which may contain foreign matter or has been
previously used should not be used.

MAXIMUM LOAD LIMITS
Maximum trailer loads
Never allow the total trailer load to exceed the
value specified in the following Towing
Load/Specification Chart found in this section.
The total trailer load equals trailer weight plus its
cargo weight.● When towing a trailer load of 3,500 lbs.
(1,587 kg) or more, trailers with a brake
system MUST be used.
The maximum Gross Combined Weight Rating
(GCWR) should not exceed the value specified
in the following Towing Load/Specification Chart.
The GCWR equals the combined weight of the
towing vehicle (including passengers and cargo)
plus the total trailer load. Towing loads greater
than these or using improper towing equipment
could adversely affect vehicle handling, braking
and performance.
The ability of your vehicle to tow a trailer is not
only related to the maximum trailer loads, but also
the places you plan to tow. Tow weights appro-
priate for level highway driving may have to be
reduced for low traction situations (for example,
on slippery boat ramps) .
Temperature conditions can also affect towing.
For example, towing a heavy trailer in high outsidetemperatures on graded roads can affect engine
performance and cause overheating. The engine
protection mode, which helps reduce the chance
of engine damage, could activate and automati-
cally decrease engine power. Vehicle speed may
decrease under high load. Plan your trip carefully
to account for trailer and vehicle load, weather
and road conditions.
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 col-
lision. Be especially careful when driving.
If the vehicle cannot maintain a safe driv-
ing speed, pull to the side of the road in a
safe area. Allow the engine to cool and
return to normal operation. For additional
information, refer to “If your vehicle over-
heats” in the “In case of emergency” sec-
tion of this manual.
CAUTION
Vehicle damage resulting from improper
towing procedures is not covered by
INFINITI warranties.

10-18Technical and consumer information

●While going downhill, the weight of the
trailer pushing on the tow vehicle may de-
crease overall stability. Therefore, to main-
tain adequate control, reduce your speed
and shift to a lower gear. Avoid long or
repeated use of the brakes when descend-
ing a hill, as this reduces their effectiveness
and could cause overheating. Shifting to a
lower gear instead provides “engine brak-
ing” and reduces the need to brake as fre-
quently.
● If the engine coolant temperature rises to a
high temperature, refer to “If your vehicle
overheats” in the “In case of emergency”
section of this manual.
● Trailer towing requires more fuel than normal
circumstances.
● Avoid towing a trailer for your vehicle’s first
500 miles (805 km) .
● For the first 500 miles (805 km) that you do
tow, do not drive over 50 mph (80 km/h).
● Have your vehicle serviced more often than
at intervals specified in the recommended
Maintenance Schedule in the “Maintenance
and schedules” section of this manual. ●
When making a turn, your trailer wheels will
be closer to the inside of the turn than your
vehicle wheels. To compensate for this,
make a larger than normal turning radius
during the turn.
● Crosswinds and rough roads will adversely
affect vehicle/trailer handling, possibly caus-
ing vehicle sway. When being passed by
larger vehicles, be prepared for possible
changes in crosswinds that could affect ve-
hicle handling.
Do the following if the trailer begins to sway: 1. Take your foot off the accelerator pedal to allow the vehicle to coast and steer as
straight ahead as the road conditions allow.
This combination will help stabilize the ve-
hicle
– Do not correct trailer sway by steering or applying the brakes.
2. When the trailer sway stops, gently apply the brakes and pull to the side of the road in a
safe area.
3. Try to rearrange the trailer load so it is bal- anced as described in this section. ●
Be careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal pass-
ing. Remember, the length of the trailer must
also pass the other vehicle before you can
safely change lanes.
● Downshift the transmission to a lower gear
for engine braking when driving down steep
or long hills. This will help slow the vehicle
without applying the brakes.
● Avoid holding the brake pedal down too long
or too frequently. This could cause the
brakes to overheat, resulting in reduced
braking efficiency.
● Increase your following distance to allow for
greater stopping distances while towing a
trailer. Anticipate stops and brake gradually.
● INFINITI recommends that the cruise control
not be used while towing a trailer.
● Some states or provinces have specific
regulations and speed limits for vehicles that
are towing trailers. Obey the local speed
limits.
● Check your hitch, trailer wiring harness con-
nections, and trailer wheel lug nuts after
50 miles (80 km) of travel and at every break.
