jump cable INFINITI QX50 2021 Owner's Manual

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 2 vehicles to bring their bat-
teries 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 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.

JUMP STARTING
If jump starting is necessary, see “Jump start-
ing” (P. 6-5). If the engine does not start by
jump starting, the battery may have to be
replaced. It is recommended that you visit an
INFINITI retailer for this service.
CAUTION
• Do not ground accessories directly to the
battery terminal. Doing so will bypass
the variable voltage control system and
the vehicle battery may not charge
completely.
• Use electrical accessories with the en-
gine running to avoid discharging the ve-
hicle battery.
NOTE:
If the battery is completely drained the
transmission will not manually shift to other
positions.
Your vehicle is equipped with a variable volt-
age control system. This system measures
the amount of electrical discharge from the
battery and controls voltage generated by
the generator.
The current sensor
OAis located near the
battery along the negative battery cable. If
you add electrical accessories to your vehicle,
be sure to ground them to a suitable body
ground such as the frame or engine block
area.
