3-4.5 High Voltage Battery Damage And Fluid Leaks
The high voltage battery contains electrolyte solution. To avoid exposure to electrolyte
solution and serious personal injury, always wear appropriate solvent resistant Personal
Protective Equipment (PPE) and read the following precautions:
• Electrolyte solution is a skin irritant.
• Electrolyte solution is an eye irritant – If contact with eyes, rinse with plenty of water andsee a doctor immediately.
• If electrolyte leak occurs, wear appropriate solvent resistant PPE and use a dry cloth to clean up the spilled electrolyte. Be sure to adequately ventilate the area.
• Electrolyte solution is highly flammable.
• Electrolyte liquid or fumes that have come into contact with water vapors in the air will create an oxidized substance. This substance may irritate skin and eyes. In these cases,
rinse with plenty of water and see a doctor immediately.
• Electrolyte fumes (when inhaled) can cause respiratory irritation and acute intoxication. Move to fresh air and wash mouth with water. See a doctor immediately.
In cases of battery case breach or electrolyte leakage, contact the fire department immediately. If you must
walk away from the vehicle, notify an appropriate responder of the fact that the vehicle is a hybrid vehicle
and contains a high voltage system and warn all others.
High Voltage Battery Electrolyte Solution Characteristics: • Clear in color
• Sweet odor
• Similar viscosity to water
• Since the high voltage battery is made up of many small sealed battery modules, electrolyte solutionleakage should be minimal.
NOTE:
Other fluids in the vehicle (such as engine oil, washer fluid, brake fluid, coolant, etc.) are
the same as those in a conventional vehicle.

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.

4. Start the engine of the booster vehicle (A) and let it run for a few minutes.
5. Start the hybrid system of the vehicle being jump started (B) .
6. After starting the hybrid system, carefully disconnect the negative cable and then the positivecable ( ) .
7. Reinstall the fuse box cover.
NOTE:
If it is not possible to turn the hybrid system ON by following this procedure, contact
an INFINITI retailer immediately.
4-2 Shift Selector Lever Lock Release
If the 12-volt battery is low or discharged, the selector lever cannot be moved from the Park (P) position. If a
booster battery is not available, the selector lever lock can be manually released. To manually release the
selector lever lock, perform the following procedure: 1. Push the ignition switch to the LOCK or OFF position.
2. Apply the parking brake.
3. Remove the shift lock cover (A) using a suitable tool.
4. Push down the shift lock (B) as shown in the illustration.
5. Push the selector lever button (C) and move the selectorlever to the Neutral (N) position (D) while holding down
the shift lock.

35. Follow the procedure below to remove the battery pack from inside the trunk room.a. Attach carabiners (A) of sufficient capacity to hold battery weight, in the positions as shown
in the figure, then connect a belt slinger (B) to it.
DANGER
Touching high voltage components without wearing appropriate Personal Protective
Equipment (PPE) will cause electrocution.
b. Slightly lift battery pack by using an enginecrane (A) .
DANGER

d. Lift up the battery pack and remove it from thetrunk room.
• Be careful that the engine crane does not contactthe trunk lid.
• Apply protection so that no scratches or other damage occurs on the vehicle body or trunk lid.
36. Move battery pack to the workbench and place it with the upper battery cover up.
To avoid battery pack damage, gently lower battery pack when setting it on its side.
6-3 High Voltage Battery Recycling
