Two methods exist in Nissan and Infinity vehicles. Some models use method 1. In this case, insert the Intelligent Key in the port provided. It will be found to the left of the steering column. It might be horizontal (first image) or vertical (second image).
If an attempt is made to start the vehicle with a discharged Intelligent Key, a guide light will illuminate at the port. Insert the key fob with the buttons up in the horizontal 
port or with the buttons facing the door in the vertical port. Make sure the key ring side is out.
Once the key fob is inserted, the vehicle can be started as normal by pressing the Start / Stop ignition button while depressing the brake. Note that the port does not recharge the fob’s battery.
If a port does not exist, method 2 comes into play. Simply touch the ignition switch with the Intelligent Key (a chime will sound). Push the ignition Start / Stop button while depressing the brake pedal within 10 seconds after the chime sounds to start the engine.
And finally, in the Infiniti QX30, the Start / Stop button appears to ‘float’ above the dashboard. Pull it away exposing the ignition switch. If necessary the tip of the mechanical key can be used as a pry bar.
Please, please, do NOT try this if you do NOT have a tapered key as shown above! Insert the tapered end of the key fob into the switch and turn to start the car old school style.
Note: If you have made an attempt to start the vehicle without success, there may be residual pressure in 
the brake system and a new warning light may appear (left) or text message to Step on the Brake. Press the brake pedal very, very hard when trying to start the vehicle again to be sure that the release switch behind the pedal is engaged. Or wait a few minutes and try again.

the lock knob at the back of the Intelligent Key (remote control or ‘clicker’). Use the mechanical key in the driver’s door key cylinder to unlock the door.
The second key fob is the spitting image of the fob used by the Mercedes-Benz folks for years. A few old Chrysler Corp. (now FCA) vehicles use it too.
As noted, the key hole on nearly all Nissan and Infiniti models is visible at the back of the driver’s door handle, and the mechanical key can be used to unlock it. Two exceptions to this are the Nissan GT-R and the Infiniti QX80. The key hole is a bit hidden, behind the front of the driver’s door handle and a cap that must be removed.
To access the key hole, press the rear end of the driver’s door handle to lift up the front end, just as you would normally to get inside. Note the cap shown in the image (above right, A). While holding the door handle out, use the mechanical key and turn the cap counterclockwise to remove it. Once removed, the key hole is exposed and the mechanical key can at last be used to unlock the driver’s door (above right).
In the 2025, the QX80 offered a new feature — flush door handles that extend when the key fob approaches the vehicle. If the battery in the fob is weak or dead, this will not occur. Getting to the key hole is a process similar to that for the GT-R. Press the front of the door handle inward. This rotates the rear of the handle outward (right, upper). The handle can then be pulled open. Do so as far as it will go exposing the key hole beneath the back of the handle (right, lower). You can now use the mechanical key to unlock the car.
Three Things to Know about Automatic Braking
Automatic Braking
The news in March 2016 is that 20 auto manufacturers and counting have agreed to roll out automatic braking in their cars by the 2022 model year. These are terrific systems and a technology we love and we only argue that there is little reason other than cost to wait a full six years for full roll out.
1) Naming
Pre-collision System, Auto Braking, Automatic Emergency Braking, Autonomous Emergency Braking, Collision Avoidance – these are all names for the same thing and serve only to pump up the egos of manufacturers. There is simply no reason for multiple naming schemes that confuse the average driver who has more than enough to remember about his or her car. Anti-lock brakes has satisfied everyone from the start and never needed embellishment. The trend that somehow allows each manufacturer to give its own moniker to every new safety system is senseless and needs to stop.
Standardize on one name. Period.
2) Presentation
Subaru gets a gold star here. It has been advertising its Eye Sight system for some time, using unmanned cars aimed at static obstacles. By contrast, Nissan and Infiniti have been advertising their systems using drivers in traffic who are simply not paying attention. Hyundai went this route with its Super Bowl ad featuring Ryan Reynolds and Volkswagen has recently got into the distracted driver act. Mercedes has gone both ways, using an obstacle course in one ad and a driver who actually puts a child in the driver’s seat of a fully autonomous vehicle in another. Have the airbags been removed??
We’ve taken Mercedes-Benz and Nissan to task for their advertising in the past. Safety systems are no substitute for paying attention while behind the wheel and certainly not an excuse for essentially teaching drivers that their new car doesn’t need them to pay attention to the road or to the safety of their passengers.
3) Liability
A self driving Google car, with a driver on board but not in control, was recently involved in an accident in California while in testing and Google said a very funny thing. Its car turned into a city bus and the company said “In this case, we clearly bear some responsibility…”. Some responsible? Who else is there to blame?
The industry says that liability issues surrounded autonomous systems have yet to be ironed out. Months ago, Volvo said flatly that it would take responsibility for any accidents that result from a failure of its autonomous features. The roll out of automatic braking is underway and there is no more time to decide. If auto manufacturers are going to install systems that they will claim will stop a vehicle before a collision, then those manufacturers have placed themselves in the path of liability.
This is a collision that cannot be avoided.
