2020 INFINITI QX80 Owner's Manual

COLD pressure:
After the vehicle has been parked for
three hours or more or driven less
than 1 mile (1.6 km).
COLD tire pressures are shown on
the Tire and Loading Information
label affixed to the driver side center
pillar.
After adjusting tire pressure to the COLD
tire pressure, the display of the tire pressure
information may show higher pressure than
the COLD tire pressure after the vehicle has
been driven more than 1 mile (1.6 km). This is
because the tire pressurizes as the tire
temperature rises. This does not indicate a
system malfunction.
Stowing the damaged tire and tools
1. Securely store the damaged tire, jack and tools in the storage area.
2. Close the cargo floor cover.
3. Replace the cargo floor board.
4. Close the liftgate.
WARNING
. Always make sure that the spare tire
and jacking equipment are properly
secured after use. Such items can
become dangerous projectiles in an accident or sudden stop.
. The full-size temporary use only
spare tire (if so equipped) is designed
for emergency use. (See specific in-
structions under the heading “Wheels
and tires” (P.8-27).) To start your engine with a booster battery,
the instructions and precautions below must
be followed.
WARNING
.
If done incorrectly, jump starting can
lead to a battery explosion, resulting
in severe injury or death. It could also
damage your vehicle.
. Explosive hydrogen gas is always
present in the vicinity of the battery.
Keep all sparks and flames away from
the battery.
. Do not allow battery fluid to come
into contact with eyes, skin, clothing
or painted surfaces. Battery fluid is a
corrosive sulphuric acid solution
which can cause severe burns. If the
fluid should come into contact with
anything, immediately flush the con-
tacted area with water.
. Keep the battery out of the reach of
children.
. The booster battery must be rated at
12 volts. Use of an improperly rated
battery can damage your vehicle.
. Whenever working on or near a
battery, always wear suitable eye
protectors (for example, goggles or

WARNING
Always follow the instructions below.
Failure to do so could result in damage to
the charging system and cause personal
injury.
1. Remove the engine compartment cover, if necessary. See “Engine compartment
check locations” (P.8-3).
2. If the booster battery is in another vehicle
, position the two vehicles (and) to bring their batteries into close
proximity to each other. Do not allow the two vehicles to touch.
3. Apply parking brake. Move the shift lever to the P (Park) position. Switch off all
unnecessary electrical systems (light,
heater, air conditioner, etc.).
4. Remove vent caps on the battery (if so equipped). Cover the battery with a
firmly wrung out moist cloth
to reduce
explosion hazard.
5. Connect jumper cables in the sequence as illustrated (
???).

CAUTION
.Always connect positive (+) to posi-
tive (+) and negative (−) to body
ground (as illustrated) — not to the
battery.
. Make sure the jumper cables do not
touch moving parts in the engine
compartment and that clamps do
not contact any other metal.
6. Start the engine of the booster vehicle
and let it run for a few minutes.
7. Keep the engine speed of the booster vehicle
at about 2,000 rpm, and start
the engine of the vehicle being jump
started
.
CAUTION
Do not keep the starter motor engaged
for more than 10 seconds. If the engine
does not start right away, push the
ignition switch to the OFF position and
wait 10 seconds before trying again.
8. After starting your engine, carefully disconnect the negative cable and then
the positive cable (

Be sure to dispose of the cloth used to
cover the vent holes as it may be
contaminated with corrosive acid.
10. Put the battery cover on. Do not attempt to start the engine by
pushing.
CAUTION
.
Automatic transmission models can-
not 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 or
coolant reservoir cap while the en-
gine is still hot. When the radiator
cap or coolant reservoir cap is re-
moved, 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
at a fast idle (approximately 1,500 rpm)
until the temperature gauge indication
returns to normal.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from the
radiator 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.
5. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. 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
leaking 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.
7. After the engine cools down, check the coolant level in the reservoir tank with
the engine running. Add coolant to the
reservoir tank if necessary. Have your
vehicle repaired. It is recommended you
visit an INFINITI retailer for this service.
IF YOUR VEHICLE OVERHEATS

When towing your vehicle, all State (Pro-
vincial in Canada) and local regulations for
towing must be followed. Incorrect towing
equipment could damage your vehicle. Tow-
ing instructions are available from an
INFINITI retailer. Local service operators
are familiar with the applicable laws and
procedures for towing. To assure proper
towing and to prevent accidental damage to
your vehicle, INFINITI recommends that you
have a service operator tow your vehicle. It is
advisable to have the service operator care-
fully read the following precautions.
WARNING
.Never ride in a vehicle that is being
towed.
. Never get under your vehicle after it
has been lifted by a tow truck.
CAUTION
.When towing, make sure that the
transmission, axles, steering system
and powertrain are in working con-
dition. If any of these conditions
apply, dollies or a flatbed tow truck
must be used. .
Always attach safety chains before
towing.
