INFINITI Q70 HYBRID 2015 Dismantling Guide

3-4.3 Water Submersion
DANGER
Damage level of submerged vehicle may not be apparent. Handling a submerged
vehicle without appropriate Personal Protective Equipment (PPE) will result in serious
injury or death from electrical shock.
•The ignition switch of the submerged vehicle must be turned OFF first, if possible.
Then the vehicle must be completely out of the water and drained to avoid electrical shock.
•
Always wear appropriate Personal Protective Equipment (PPE) and remove/drain
water before removing the service plug when working on a vehicle after a fire or
submersion to avoid electrical shock.
•
If the vehicle is in the water, to avoid electrical shock NEVER touch the high voltage
components, harnesses or service plug. PPE must always be worn when touching or
working on high voltage components.
3-4.4 Vehicle Fire
• Always utilize full Personal Protective Equipment (PPE) and self-contained breathing apparatus during fire fighting operations. Smoke from a Q70 HYBRID vehicle fire is
similar to smoke from a conventional vehicle fire.
• In the case of extinguishing a fire with water, large amounts of water from a fire hydrant (if possible) must be used. DO NOT extinguish fire with a small amount of water.
In the event of a small fire, a Type ABC fire extinguisher may be used for an electrical fire
caused by wiring harnesses, electrical components, etc. or oil fire.
In case of vehicle fire, contact fire department immediately and extinguish the fire if possible. If you must
walk away from the vehicle, notify an appropriate responder or a rescue person of the fact that the vehicle is
a hybrid vehicle that contains a high voltage system and warn all others.

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. Jump Starting
To start the hybrid system with a booster battery, the instructions and precautions below must be followed.
If done incorrectly, jump starting can lead to a 12-volt battery explosion, resulting in severe
personal injury or death. It could also damage your vehicle.
Jump starting provides power to the 12-volt system to allow the electrical systems to operate. The electrical
systems must be operating to allow the high voltage battery to be charged. Jump starting does not charge
the high voltage battery.
Discharged 12-volt battery may cause the following issues: • The instrument cluster cannot be displayed while the ignition switch is turned ON. (The hybridsystem cannot start.)
• Headlamps, horn, etc. are weak.
•To avoid electrical shock, the high voltage battery CANNOT be jump started.
• Explosive hydrogen gas is always present in the vicinity of the 12-volt battery. Keep all sparks and flames away from the 12-volt battery. Make sure the vent tube is mounted.
• Do not allow battery fluid to come into contact with eyes, skin, clothing or painted surfaces. Battery fluid is a corrosive sulfuric acid solution that can cause severe burns.
If the fluid comes into contact with anything, immediately flush the contacted area
with water.
• The booster battery must be rated at 12 volts. Use of an improperly rated battery can damage the vehicle.
• Whenever working on or near a 12-volt 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 12-volt battery when jump starting.
• Do not attempt to jump start a frozen battery. It could explode and cause serious injury.
• Q70 HYBRID is equipped with an automatic cooling fan. It could come on at any time. Keep hands and other objects away from it.
• Always follow the jump starting instructions below. Failure to do so could result in damage to the charging system and cause personal injury.

4-1 Jump Starting ProceduresJumper 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 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. 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, contact
an INFINITI retailer immediately.
8. Put the fuse cover and the engine compartment cover back to the original location.
