2021 INFINITI Q60 COUPE change time

4. Drive at economical speeds and dis-
tances.
.Observing the speed limit and not
exceeding 60 MPH (97 km/h) (where
legally allowed) can improve fuel
efficiency due to reduced aerody-
namic drag.
.Maintaining a safe following distance
behind other vehicles reduces unne-
cessary braking.
.Safely monitoring traffic to anticipate
changes in speed permits reduced
braking and smooth acceleration
changes.
.Select a gear range suitable to road
conditions.
5. Use cruise control.
.Using cruise control during highway
driving helps maintain a steady speed.
.Cruise control is particularly effective
in providing fuel savings when driving
on flat terrains.
6. Plan for the shortest route.
.Utilize a map or navigation system to
determine the best route to save time.
7. Avoid idling.
.Shutting off your engine when safe
for stops exceeding 30-60 seconds
saves fuel and reduces emissions.8. Buy an automated pass for toll roads.
.Automated passes permit drivers to
use special lanes to maintain cruising
speed through the toll and avoid
stopping and starting.
9. Winter warm up.
.Limit idling time to minimize impact to
fuel economy.
.Vehicles typically need no more than
30 seconds of idling at start-up to
effectively circulate the engine oil
before driving.
.Your vehicle will reach its ideal oper-
ating temperature more quickly while
driving versus idling.
10. Keeping your vehicle cool.
.Park your vehicle in a covered parking
area or in the shade whenever possi-
ble.
.When entering a hot vehicle, opening
the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C system..Keep your engine tuned up.
.Follow the recommended scheduled
maintenance.
.Keep the tires inflated to the correct
pressure. Low tire pressure increases tire
wear and lowers fuel economy.
.Keep the wheels in correct alignment.
Improper alignment increases tire wear
and lowers fuel economy.
.Use the recommended viscosity engine
oil. (See “Engine oil and oil filter recom-
mendation” (P.10-6).)

8-8Do-it-yourself
Engine oil and filter
1. Place a large drain pan under the drain
plug.
2. Remove the oil filler cap.
3. Remove the drain plug
with a wrench
and completely drain the oil.
CAUTION
Be careful not to burn yourself, as the
engine oil is hot.
.Waste oil must be disposed of prop-
erly.
.Check your local regulations.
4. (Perform steps 4 to 7 only when the
engine oil filter change is needed.)
Loosen the oil filter
with an oil filter
wrench. Remove the oil filter by turning it
by hand.
5. Wipe the engine oil filter mounting sur-
face with a clean rag.
CAUTION
Be sure to remove any old rubber gasket
remaining on the mounting surface of
the engine. Failure to do so could lead toengine damage.
6. Coat the gasket on the new filter with
clean engine oil.
7. Screw in the oil filter clockwise until a
slight resistance is felt, then tighten
additionally more than 2/3 turn.
Oil filter tightening torque:
11 to 15 ft-lb
(14.7 to 20.6 N·m)
8. Clean and re-install the drain plug with a
new washer. Securely tighten the drain
plug with a wrench.
Drain plug tightening torque:
22 to 29 ft-lb
(29.4 to 39.2 N·m)
Do not use excessive force.
9. Refill engine with recommended oil and
install the oil filler cap securely.
See “Capacities and recommended
fluids/lubricants” (P.10-2) for drain and
refill capacity. The drain and refill capa-
city depends on the oil temperature and
drain time. Use these specifications for
reference only. Always use the dipstick
to determine the proper amount of oil in
the engine.10. Start the engine and check for leakage
around the drain plug and the oil filter.
Correct as required.
11. Turn the engine off and wait more than
15 minutes. Check the oil level with the
dipstick. Add engine oil if necessary.
After the operation
1. Install the engine undercover into posi-
tion as the following steps.
a. Pull the center of the small plastic clip
out.
b. Hold the engine undercover into posi-
tion.
c. Insert the clip through the undercover
into the hole in the frame, then push
the center of the clip in to lock the clip
in place.
d. Install the other bolts that hold the
undercover in place. Be careful not to
strip the bolts or over-tighten them.
2. Lower the vehicle carefully to the
ground.
3. Dispose of waste oil and filter properly.
WARNING
.Prolonged and repeated contact with
used engine oil may cause skin cancer.

9-4Maintenance and schedules
and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying,
wear or damage.
Steering wheel:Check for changes in the
steering conditions, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes:Make sure that
all warning lights and chimes are operating
properly.
Windshield defroster:Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*:Check that
the wipers and washer operate properly and
that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time
you check the engine oil or refuel).
Battery*:Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Vehicles operated in high temperatures or
under severe condition require frequent
checks of the battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:1.Installation or extended use of electro-
nic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.)
2.Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
Brake fluid level*:Make sure that the brake
fluid level is between the MAX and MIN lines
on the reservoir.
Engine coolant level*:Check the coolant
level when the engine is cold.
Intercooler coolant level*:Check the coolant
level when the engine is cold.
Engine drive belts*:Make sure that no belt is
frayed, worn, cracked or oily.
Engine oil level*:Check the level after
parking the vehicle on a level spot and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the oil
pan.
Exhaust system:Make sure there are no
loose supports, cracks or holes. If the sound
of the exhaust seems unusual or there is a
smell of exhaust fumes, immediately have
the exhaust system inspected. It is recom-
mended you visit an INFINITI retailer for this
service. (See “Precautions when starting anddriving” (P.5-4).)
Fluid leaks:Check under the vehicle for fuel,
oil, water or other fluid leaks after the
vehicle has been parked for a while. Water
dripping from the air conditioner after use is
normal. If you should notice any leaks or if
gasoline fumes are evident, check for the
cause and have it corrected immediately.
Radiator and hoses:Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, defor-
mation, rot or loose connections.
Underbody:The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances, otherwise rust will form on the
floor pan, frame, fuel lines and around the
exhaust system. At the end of winter, the
underbody should be thoroughly flushed
with plain water, being careful to clean
those areas where mud and dirt may accu-
mulate. For additional information, see
“Cleaning exterior” (P.7-2).
Windshield washer fluid*:Check that there
is adequate fluid in the reservoir.

STANDARD MAINTENANCE

your service station manager.
If you use oxygenate-blend gasoline, please
take the following precautions as the usage
of such fuels may cause vehicle performance
problems and/or fuel system damage.
.The fuel should be unleaded and have an
octane rating no lower than that re-
commended for unleaded gasoline.
.If an oxygenate-blend, excepting a
methanol blend, is used, it should con-
tain no more than 15% oxygenate.
.If a methanol blend is used, it should
contain no more than 5% methanol
(methyl alcohol, wood alcohol). It should
also contain a suitable amount of ap-
propriate cosolvents and corrosion in-
hibitors. If not properly formulated with
appropriate cosolvents and corrosion
inhibitors, such methanol blends may
cause fuel system damage and/or vehi-
cle performance problems. At this time,
sufficient data is not available to ensure
that all methanol blends are suitable for
use in INFINITI vehicles.
If any undesirable driveability problems such
as engine stalling or hard hot starting are
experienced after using oxygenate-blend
fuels, immediately change to a non-oxyge-
nate fuel or a fuel with a low blend of MTBE.
Take care not to spill gasoline during
refueling. Gasoline containing oxygenatescan cause paint damage.
E-15 fuel
E-15 fuel is a mixture of approximately 15%
fuel ethanol and 85% unleaded gasoline. E-
15 can only be used in vehicles designed to
run on E-15 fuel. U.S. government regula-
tions require fuel ethanol dispensing pumps
to be identified with small, square, orange
and black label with the common abbrevia-
tion or the appropriate percentage for that
region.
E-85 fuel
E-85 fuel is a mixture of approximately 85%
fuel ethanol and 15% unleaded gasoline. E-
85 can only be used in a Flexible Fuel Vehicle
(FFV). Do not use E-85 fuel in your vehicle.
U.S. government regulations require fuel
ethanol dispensing pumps to be identified
by a small, square, orange and black label
with the common abbreviation or the appro-
priate percentage for that region.
Fuel containing MMT
MMT, or methylcyclopentadienyl manga-
nese tricarbonyl, is an octane boosting
additive. INFINITI does not recommend the
use of fuel containing MMT. Such fuel may
adversely affect vehicle performance, in-
cluding the emissions control system. Note
that while some fuel pumps label MMTcontent, not all do, so you may have to
consult your gasoline retailer for more de-
tails.
Aftermarket fuel additives
INFINITI does not recommend the use of any
aftermarket fuel additives (Example: fuel
injector cleaner, octane booster, intake valve
deposit removers, etc.) which are sold com-
mercially. Many of these additives intended
for gum, varnish or deposit removal may
contain active solvent or similar ingredients
that can be harmful to the fuel system and
engine.
Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended above can
cause persistent, heavy spark knock. (Spark
knock is a metallic rapping noise.) If severe,
this can lead to engine damage. If you
detect a persistent heavy spark knock even
when using gasoline of the stated octane
rating, or if you hear steady spark knock
while holding a steady speed on level roads,
it is recommended you have an INFINITI
retailer correct the condition. Failure to
correct the condition is misuse of the
vehicle, for which INFINITI is not respon-
sible.
Incorrect ignition timing will result in knock-
ing, after-run or overheating. This in turn
