Drain and refill INFINITI QX50 2020 Owners Manual

DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
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. Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow tires.
3. Tire chains may be used. For additional information, refer to “Tire chains” in the
“Do-it-yourself” section of this manual.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
∙ A scraper and stiff-bristled brush to re- move ice and snow from the windows
and wiper blades.
∙ A sturdy, flat board to be placed under the jack to give it firm support.
∙ A shovel to dig the vehicle out of snow- drifts.
∙ Extra washer fluid to refill the windshield-washer fluid reservoir.
DRIVING ON SNOW OR ICE
WARNING
∙ Wet ice (32°F, 0°C and freezing rain),very cold snow or ice can be slick and very
hard to drive on. The vehicle will have
much less traction or “grip” under these
conditions. Try to avoid driving on wet
ice until the road is salted or sanded.
∙ Whatever the condition, drive with cau- tion. Accelerate and slow down with
care. If accelerating or downshifting too
fast, the drive wheels will lose even more
traction.
∙ Allow more stopping distance under these conditions. Braking should be
started sooner than on dry pavement.
∙ Allow greater following distances on slippery roads.
∙ Watch for slippery spots (glare ice). These may appear on an otherwise clear
road in shaded areas. If a patch of ice is
seen ahead, brake before reaching it. Try
not to brake while on the ice, and avoid
any sudden steering maneuvers.
∙ Do not use the cruise control on slippery roads.
5-192Starting and driving

CAUTION
Be careful not to burn yourself, as the en-
gine oil is hot.
WARNING
∙ Prolonged and repeated contact withused engine oil may cause skin cancer.
∙ Try to avoid direct skin contact with used oil. If skin contact is made, wash thor-
oughly with soap or hand cleaner as soon
as possible.
∙ Keep used engine oil out of reach of children.
4. Loosen the oil filter with an oil filter wrench by turning it counterclockwise.
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 gasket material
remaining on the sealing surface of the en-
gine. Failure to do so could lead to an oil
leak and engine damage.
∙ The dipstick must be inserted in place toprevent oil spillage from the dipstick hole
when filling the engine with oil.
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 ad-
ditionally 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. Do not use excessive
force.
Drain plug tightening torque: 22 to 29 ft-lb (29.4 to 39.2 N·m)
9. Refill the engine with the recommended oil through the oil filler opening, and in-
stall the oil filler cap securely. For additional information about drain and
refill capacity, refer to “Recommended
fluids/lubricants and capacities” in the “Tech-
nical and consumer information” section of
this manual. The drain and refill capacity de-
pends 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. 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. Reinstall engine protectors in reverse or-der of removal.
2. Lower the vehicle carefully to the ground.
3. Reset the oil control system. For addi- tional information, refer to “Vehicle in-
formation display” in the “Instruments
and controls” section of this manual.
∙ Dispose of waste oil and filter properly.
∙ Check your local regulations.
