2018 INFINITI Q60 engine overheat

5-132Starting and driving
a straight road for a period of time.
.After the engine is started, the steering
wheel may move if the steering wheel
was turned to the fully locked position
while the ignition switch was in the OFF
position.
.After the vehicle is tested on the 4-wheel
dynamometer, the steering wheel may
turn slightly even when driving on a
straight road. To return the steering
wheel to the normal position, drive the
vehicle on a straight road for a period of
time.
You may hear a noise under the following
conditions. However, this is not a malfunc-
tion.
.When the engine is started or stopped.
.When the steering wheel is turned in the
full lock position.BRAKING PRECAUTIONS
The brake system has two separate hydrau-
lic circuits. If one circuit malfunctions, you
will still have braking at two wheels.
Vacuum assisted brakes
The brake booster aids braking by using
engine 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
vehicle and the stopping distance will be
longer.
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.
WARNING
.While driving on a slippery surface,
be careful when braking, acceleratingor downshifting. Abrupt braking or
accelerating could cause the wheels
to skid and result in an accident.
.If the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.
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 pedal
to 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 perfor-
mance.
This procedure is described in the vehicle
service manual. It is recommended you visit

pushing.
CAUTION
.Automatic Transmission (AT) models
cannot be push-started or tow-
started. Attempting to do so may
cause transmission damage.
.Three-way catalyst equipped models
should not be started by pushing
since the three-way catalyst may be
damaged.
.Never try to start the vehicle by
towing it; when the engine starts,
the forward surge could cause the
vehicle to collide with the tow vehi-
cle.
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 while
the engine is still hot. When the
radiator 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 the P (Park) position.
Do not stop the engine.
2. Turn off the climate control. Open all the
windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed.
3. If engine overheating is caused by climb-
ing a long hill on a hot day, run the engine

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 anti-freeze and coolant protec-
tion. The anti-freeze solution contains rust
and corrosion inhibitors. Additional engine
cooling system additives are not necessary.
WARNING
.Never remove the radiator cap when
the engine is hot. Wait until the
engine and radiator cool down. Ser-
ious burns could be caused by high
pressure fluid escaping from the
radiator. See precautions in “If your
vehicle overheats” (P.6-21) of this
manual.
.The radiator is equipped with a
pressure type radiator cap. To pre-
vent engine damage, use only a
genuine NISSAN radiator cap.
CAUTION
.Never use any cooling system addi-
tives such as radiator sealer. Addi-
tives may clog the cooling system and
cause damage to the engine, trans-mission 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 protec-
tion to −34°F (−37°C). If additional
freeze protection is needed due to
weather where you operate your
vehicle, add Genuine NISSAN Long
Life Antifreeze/Coolant (blue) con-
centrate following the directions on
the container. If an equivalent cool-
ant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue) is
used, follow the coolant manufac-
ture’s instructions to maintain mini-
mum antifreeze protection to −34°F
(−37°C). The use of other types of
coolant solutions other than Genuine
NISSAN Long Life Antifreeze/Cool-
ant (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 coolant other than Genuine
NISSAN Long Life Antifreeze/Cool-
ant (blue), including Genuine NISSAN
Long Life Antifreeze/ Coolant
(green), or the use of non-distilledwater will reduce the life expectancy
of the factory-fill coolant. Refer to
the “9. Maintenance and schedules”
section of this manual for more de-
tails.

CHECKING ENGINE COOLANT
LEVEL
Check the coolant level in the reservoir tank
when the engine is running and after it
reaches normal operating temperature. If
the coolant level is below MIN level
, add
coolant up to the MAX level. If the
reservoir tank is empty, check the coolant
level in the radiatorwhen the engine is cold.
If there is insufficient coolant in the radiator,
fill the radiator with coolant up to the filler
cap above the radiator upper hose opening
and also add it to the reservoir tank up to the
MAX level
. Put on the filler cap above the
radiator upper hose and with the reservoir
cap open, start the engine. Run the engineuntil it reaches normal operating tempera-
ture. Add coolant up to the MAX level
.
Tighten the cap securely after adding engine
coolant.
If the cooling system requires coolant fre-
quently, have it checked. It is recommended
you visit an INFINITI retailer for this
service.
CHANGING ENGINE COOLANT
It is recommended that major cooling system
repairs be performed by an INFINITI retailer.
The service procedures can be found in the
appropriate 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
engine is hot.
.Never remove the radiator 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 cleaneras soon as possible.
.Keep coolant out of reach of children
and pets.
Engine coolant must be disposed of prop-
erly. Check your local regulations.

the directions on the container. If an
equivalent coolant other than BASF
Glysantin
®G48®is used, follow the
coolant manufacture’s instructions to
maintain minimum antifreeze protec-
tion to −34°F (−37°C). The use of
other types of coolant solutions
other than BASF Glysantin
®G48®
or equivalent may damage the engine
cooling system.
.The life expectancy of the factory-fill
coolant is 120,000 miles (192,000

distilled water will reduce the life
expectancy of the factory-fill cool-
ant. Refer to the “9. Maintenance
