engine NISSAN LEAF 2017 1.G Dismantling Guide

1. About The Nissan LEAF®
This
vehicle uses two types of batteries. One is a 12-volt battery that is the same as the battery in vehicles
powered by internal combustion engines, and the other is the high-voltage battery for the traction motor
which propels the vehicle. The high-voltage battery is encased in steel and mounted underneath the vehicle.
The vehicle must be plugged-in in order for the high-voltage battery to be recharged. Additionally, the
vehicle system can recharge the high-voltage battery by converting driving force into electricity while the
vehicle is decelerating or being driven downhill. This is called regenerative charging. This vehicle is
considered to be an environmentally friendly vehicle because it does not emit exhaust gases.

4-1 Jump Starting Procedures
1. If the booster battery is in another vehicle (B) , position the two vehicles (A and B) to bring their
12-volt batteries into close proximity to each other.
DO NOT allow the two vehicles to touch.
2. Apply the parking brake.
3. Push the P (Park) position switch to place the vehicle in the P (Park) position.
4. Switch off all unnecessary electrical systems (headlights, heater, air conditioner, etc.) .
5. Place the power switch in the OFF position (if possible) .
If the 12-volt battery is discharged, the power switch cannot be moved from the
OFF position. Connect the jumper cables to the booster vehicle (B) before pushing
the power switch.
6. Ensure vent caps are level and tight.
7. Connect jumper cables in the sequence as illustrated () . • 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 motor compartment and that the cable clamps do not contact any other metal.
8. Start the engine of the booster vehicle (B) .
9. While the booster vehicle (B) engine is running, turn the power switch ON while pressing the brake pedal in order to place the LEAF in READY mode.
If the system does not start right away, push the power switch to the OFF position and wait
at
