2018 INFINITI Q50 HYBRID Roadside Assistance Guide

3-3 Vehicle Immobilization and Stabilization
If
possible, immobilize the vehicle by turning the 12-volt system OFF and stabilize it with a wheel chock(s) .
Stabilize the vehicle with wooden blocks or by removing air from the tires. • To avoid electrical shock, do not put wooden blocks or wheel chock(s) under the
high-voltage
components and harnesses as shown following. AAYIA0185ZZ
RAG–17

3-4 Turning OFF the Ignition Switch
1. Check the READY indicator status. If it is ON, the high-voltage system is active.
2.

Press the ignition switch once to turn OFF the high-
voltage system. Then verify whether the READY indicator is OFF.
3.
If possible, keep the Infiniti Intelligent Key at least
5 meters (16 feet) away from the vehicle to prevent
accidentally turning ON the hybrid system while the
roadside assistance is in progress.
3-5 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.
• 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.
Only first responders wearing appropriate Personal Protective Equipment (PPE) should shut down the
vehicle. After shut down, standard towing/recovery procedures can be used. Refer to 4-3 Towing
(RAG–24) . ACC

3-6 Vehicle Fire
• Always utilize full Personal Protective Equipment (PPE) and self-contained breathing
apparatus during fire fighting operations. Smoke from a Q50 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.
3-7 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 and see 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.

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.
• Q50 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.

4-3.2 Towing Guidelines
Infiniti strongly recommends that Q50 HYBRID be towed with the driving (rear) wheels off the ground or
that a dolly be used as illustrated. • Never tow with the rear wheels on the ground or four (4) wheels on the ground (forward
or
backward) , as this may cause serious and expensive damage to the motor.
• Never tow AWD models with any of the wheels on the ground as this may cause serious and expensive damage to the powertrain.
• Transport the vehicle only after turning the ignition switch OFF.
• Safety chains or cables must be attached only to the main structural members of the vehicle. Otherwise, the vehicle body will be damaged.
• Do not use the vehicle tie down hook to free a vehicle stuck in sand, snow, mud, etc.
• Never tow a vehicle using the vehicle tie down hook.
• Always pull the cable straight out from the front of the vehicle. Never pull on the vehicle at an angle.
• Pulling devices should be routed so they do not touch any part of the suspension, steering, brake, high-voltage or cooling systems.
• Pulling devices such as ropes or canvas straps are not recommended for use in vehicle towing or recovery.
