2. Basic High Voltage Information
2-1 Battery Information
The Q50 HYBRID utilizes two batteries in order to supply both high and low voltage.
2-1.1 12-Volt Battery• The Q50 HYBRID contains a conventional lead-acid12-volt battery.
• The 12-volt battery is located in the trunk, on the left side, concealed by a trim cover (A) .
• The 12-volt battery is charged by the high voltage battery through the DC/DC converter.
2-1.2 High Voltage Battery • The Q50 HYBRID contains a high voltage battery.
• The high voltage battery is mounted in the trunk areabehind the rear seat, enclosed in a metal case and
concealed by trim cover.
• The high voltage battery stores energy at approximately 346 - 400 volts DC.
• A vent hose is provided to exhaust gasses outside the vehicle if necessary.
• An air vent (A) is located on the rear left hand lower C-pillar trim for battery cooling.
The high voltage battery supplies power to the following: • High voltage harnesses
• DC/DC converter
• Traction motor inverter
• Traction motor
• Electric air conditioner compressor

No. Component Location Description High voltage Battery
Trunk area (behind
rear seat back) The high voltage battery stores and outputs
DC power (Maximum voltage 400V) needed to
propel the vehicle.
DC/DCConverter Trunk area (mounted
to top of high voltagebattery) The DC/DC converter reduces the voltage of
the high voltage battery to provide power to
the 12-volt battery in order to operate the
vehicle’s electric components (headlights,
audio system, etc.) .
Service Plug Trunk area (below
parcel shelf; behind
access door in trimpanel) This is used to disable the high voltage system.
12-volt Battery Trunk area (left side
behind trim panel) A lead-acid battery that supplies power to the
low voltage devices.

SRS Air Bag System Components Location
The SRS air bag system must not be cut as there is a risk of short circuit and unintentional deployment of
the SRS However, the vehicle can be cut (except inflators) under the following conditions:• The front, side and curtain air bags have deployed.
• At least three (3) minutes have passed after the 12-volt battery negative (-) cable has beendisconnected and the high voltage system has been shut down.
1. Crash zone sensor (located
underhood near hood latch) 2. Supplemental front air bag
modules (Infiniti Advanced
Air Bags)3. Front seat-mounted side-
impact supplemental air bags
4. Roof-mounted curtain side-
impact supplemental air bags 5. Roof-mounted curtain side-
impact supplemental air baginflators6. C-pillar satellite sensors
(LH shown, RH similar)
7. Seat belt buckle pretensioners 8. Seat belts with pretensioners 9. B-pillar satellite sensors
10. Air bag control unit (ACU) 11. Front door satellite sensors (LH shown, RH similar)

4-1 Jump Starting Procedures
NOTE:Jumper cable connections under the hood of the Q50 HYBRID are not connected directly to
a battery. They are connected to chassis ground and a fuse box terminal. Refer to the
following instructions and the above illustration.
1. If the booster battery is in another vehicle (A) , position the two vehicles (A and B) to bring the12-volt battery and fuse box into close proximity to each other.
DO NOT allow the two vehicles to touch.
2. Apply the parking brake. Move the selector lever the P (Park) position. Switch off all unnecessary electrical systems (headlights, heater, air conditioner, etc.) .
3. Remove fuse box cover on the Q50 HYBRID and connect jumper cables in the sequence as illustrated ( ) .
For models with a steering wheel lock mechanism:
If the 12-volt battery is disconnected or discharged, the steering wheel will lock and cannot be
turned. Supply power using jumper cables before pushing the ignition switch and disengaging
the steering lock.
• Always connect positive (+) to positive (+) and negative (-) to body ground (for example, as illustrated) , not to the 12-volt battery.
• Make sure the jumper cables do not touch moving parts in the engine compartment and that the cable clamps do not contact any other metal.
• If the hybrid system does not start right away, push the ignition switch to the OFF position and wait ten (10) seconds before trying again.
