2023 INFINITI QX55 battery

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 dam-
age your vehicle.
• Explosive hydrogen gas is always pres-
ent 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 corro-
sive sulfuric acid solution which can
cause severe burns. If the fluid should
come into contact with anything, imme-
diately flush the contacted area with
water.
• Keep 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 industrial safety
spectacles) and remove rings, metal
bands, or any other jewelry. Do not lean
over the battery when jump starting.
• Do not attempt to jump start a frozen
battery. It could explode and cause seri-
ous injury.
• Your vehicle has an automatic engine
cooling fan. It could come on at any time.
Keep hands and other objects away from
it.
JUMP STARTING
In case of emergency6-5

WARNING
Always follow the instructions below. Fail-
ure to do so could result in damage to the
charging system and cause personal injury.
1. If the booster battery is in another vehicle, position the two vehicles to bring their
batteries near each other.
Do not allow the two vehicles to touch.
2. Apply the parking brake. Engage the P (Park) position. Switch off all unnecessary
electrical systems (lights, heater, air con-
ditioner, etc.). 3. Place the ignition switch to the LOCK or
OFF position.
4. Connect the jumper cables in the se- quence illustrated (
OA,OB,OC,OD).
CAUTION
• Always connect positive (+) to positive
(+) and negative (−) to body ground (for
example, strut mounting bolt, engine lift
bracket, etc.) — not to the battery.
• Make sure the jumper cables do not
touch moving parts in the engine com-
partment and that the cable clamps do
not contact any other metal. 5. Start the engine of the booster vehicle and
let it run for a few minutes.
6. Keep the engine speed of the booster ve- hicle 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, place the ignition
switch in the OFF position and wait 3 to 4
seconds before trying again.
7. After starting the engine, carefully discon- nect the negative cable and then the posi-
tive cable.

6. After the engine cools down, check thecoolant level in the engine coolant reser-
voir tank with the engine running. Add
coolant to the engine coolant reservoir
tank if necessary. Have your vehicle re-
paired. It is recommended that you visit an
INFINITI retailer for this service. When towing your vehicle, all jurisdictions
and local regulations for towing must be fol-
lowed. Incorrect towing equipment could
damage your vehicle. Towing instructions are
available from an INFINITI retailer. Local ser-
vice operators are generally familiar with the
applicable laws and procedures for towing.
To assure proper towing and to prevent ac-
cidental damage to your vehicle, INFINITI
recommends having a service operator tow
your vehicle. It is advisable to have the service
operator carefully 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 trans-
mission, axles, steering system and pow-
ertrain are in working condition. Use dol-
lies or flatbed if any of the listed systems
are not working.
• Always attach safety chains before
towing. For additional information about towing your
vehicle behind a Recreational Vehicle (RV),
see “Flat towing for all wheel drive vehicle”
(P. 10-20).
NOTE:
If the battery is completely drained, the
transmission will not manually shift to other
positions. For shifting to other positions,
charge the battery or supply power follow-
ing the jump starting procedure. Push the
park button to shift to the P (Park) position
before shifting to other positions.
TOWING RECOMMENDED BY
INFINITI
INFINITI recommends towing your vehicle
based upon the type of drivetrain. For addi-
tional information, refer to the diagrams in
this section to ensure that your vehicle is
properly towed.
TOWING YOUR VEHICLE

All-Wheel Drive (AWD) models with
Continuously Variable Transmission
(CVT)
INFINITI recommends that towing dollies be
used when towing your vehicle or place the
vehicle on a flatbed truck as illustrated.
CAUTION
Never tow AWD models equipped with a
Continuously Variable Transmission (CVT)
with any of the wheels on the ground as
this may cause serious and expensive dam-
age to the transfer case and transmission.
NOTE:
If the battery is completely drained the
transmission will not manually shift to other
positions.
VEHICLE RECOVERY (freeing a
stuck vehicle)
WARNING
To avoid vehicle damage, serious personal
injury or death when recovering a stuck
vehicle: •
Contact a professional towing service to
recover the vehicle if you have any ques-
tions regarding the recovery procedure.
• Tow chains or cables must be attached
only to main structural members of the
vehicle.
• Do not use the vehicle tie-downs to tow
or free a stuck vehicle.
• Only use devices specifically designed for
vehicle recovery and follow the manu-
facturer's instructions.
• Always pull the recovery device straight
out from the front of the vehicle. Never
pull at an angle.
• Route recovery devices so they do not
touch any part of the vehicle except the
attachment point.
If your vehicle is stuck in sand, snow, mud,
etc., use a tow strap or other device designed
specifically for vehicle recovery. Always fol-
low the manufacturer's instructions for the
recovery device.

When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to your-
self or damage to the vehicle. The following
are general precautions which should be
closely observed.
WARNING
• Park the vehicle on a level surface, apply
the parking brake securely and block the
wheels to prevent the vehicle from mov-
ing. Push the park button to engage the
P (Park) position.
• Be sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.
• If you must work with the engine run-
ning, keep your hands, clothing, hair and
tools away from moving fans, belts and
any other moving parts.
• It is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before work-
ing on your vehicle.
• Always wear eye protection whenever
you work on your vehicle.
• Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the ignition switch is in the OFF position and
the engine is not running. To avoid injury,
always disconnect the negative battery
cable before working near the fan.
• If you must run the engine in an enclosed
space such as a garage, be sure there is
proper ventilation for exhaust gases to
escape.
• Never get under the vehicle while it is
supported only by a jack. If it is necessary
to work under the vehicle, support it
with safety stands.
•
Keep smoking materials, flame and sparks
away from the fuel tank and battery.
• Because the fuel lines on gasoline engine
models are under high pressure even
when the engine is off, it is recommended
that you visit an INFINITI retailer for ser-
vice of the fuel filter or fuel lines.
CAUTION
• Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
•
Avoid contact with used engine oil and
coolant. Improperly disposed engine oil,
engine coolant and/or other vehicle fluids
can damage the environment. Always con-
form to local regulations for disposal of
vehicle fluid.
• Never leave the engine or Continuously
Variable Transmission (CVT) related
component harnesses disconnected
while the ignition switch is in the ON
position.
• Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
NOTE:
If the battery is completely drained the
transmission will not manually shift to other
positions.
This “Do-it-yourself” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine INFINITI service manual is also
available. For additional information, see
“Owner’s Manual/Service Manual order in-
formation” (P. 10-26).
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could af-
fect warranty coverage. If in doubt about any
servicing, it is recommended that you have it
done by an INFINITI retailer.
