Lamp Name Icon Description
READY Indicator (Green)
This lamp is on when the high voltage system is powered
up and the vehicle is ready to drive.
Master Warning Lamp
(Orange or Red)
This lamp is on when another warning lamp or message is
displayed in the instrument cluster.
Hybrid System Warning Lamp(Orange)
This lamp is on or blinking when:
• Malfunction has occurred in the hybrid control system and/or
• High voltage leak to vehicle chassis and/or
• Emergency shut-off system has been activated. The shut-off system activates in the following conditions:
– Front and side collisions in which the air bags are deployed.
– Certain rear collisions.
– Certain high voltage system malfunctions.

2. Basic High Voltage Information
2-1 Battery Information
The Q70 HYBRID utilizes two batteries in order to supply both high and low voltage.
2-1.1 12-volt Battery• The Q70 HYBRID contains a conventional lead-acid12-volt battery.
• The 12-volt battery is located in the trunk, left of high voltage battery, concealed by trim cover.
• The 12-volt battery is charged by the high voltage battery through the DC/DC converter.
2-1.2 High Voltage Battery • The Q70 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 approximately 346 volts DC (400V max.) .
• A vent hose is provided to exhaust gasses outside the vehicle if necessary.
• An air vent is located on the rear parcel shelf 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

voltage between each of the high voltage com-ponents.
Electric Air Condi-
tioner Compressor Engine compart-
ment (front driverside) Air conditioner compressor
Traction MotorInverter Engine compart-
ment (right rearside) Converts the DC power stored in the high volt-
age battery to three-phase AC power and con-
trols motor torque (revolution) by regulating the
motor current. The inverter has a built in high
voltage capacitor.
Traction Motor Built-into the trans-
mission Converts three-phase alternating current (AC)
power to drive power (torque) which propels
the vehicle.

4-1.1 Jump Starting Procedures
NOTE:Jumper cable connections under the hood of the Q70 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 thebattery of booster vehicle (A) and the fuse box of jumped vehicle (B) into close proximity to eachother.
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. Place the ignition switch in the “OFF” position.
• 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.
4. Connect the jumper cables in the sequence as illustrated [(1) , (2) , (3) , (4)].
5. Start the engine of the booster vehicle (A) and let it run for a few minutes.
6. Start the hybrid system of the jumped vehicle (B) in the normal manner.
7. After the hybrid system is started, carefully disconnect the jumper cables in the opposite sequence from that illustrated [(4) , (3) , (2) , (1)].
NOTE:
If it is not possible to turn the hybrid system ON by following this procedure, it is
recommended you contact an INFINITI retailer immediately.
8. Put the fuse cover and the engine compartment cover back to the original location.
