The First Drive in Your New Tesla

So, owning and driving a Tesla, or any EV is pretty much like driving the gasoline-powered cars you are used to, with a couple of exceptions related to driving and re-fueling (charging), which I will cover here.

Regenerative Braking

One of the defining features of EVs is something called regenerative braking or regen for short. In a typical car, when you take your foot off the gas the car coasts along and slowly loses speed. Most EVs do something a bit different. When you press the accelerator, the battery sends electricity to the motors, which turn the wheels. When you let off the accelerator, the process reverses: the spinning wheels now turn shaft of the motor, turning it into a dynamo, which charges the battery. If you have the energy app up in the instrument clusters in the Model S or Model X, you can see this graphically depicted. The orange arc shows you are drawing power from the battery and the green arc means you are charging the battery. With the Model 3, you see similar behavior with the energy bar that’s below the speedometer on the touchscreen.

Orange = Acceleration (using battery)Green = Regen (charging battery)

This action is called regenerative braking because it causes the car to slow down more quickly–as soon as you take your foot off the accelerator, the car will begin to slow. The behavior can seem strange at first (so now you have been warned) but most divers quickly adapt. To help the transition, the car can get set to “low” regeneration mode via the controls, but my advice to is to leave it on “normal” and adapt to it.

One of the benefits of regeneration is “one-foot driving.” Most drivers get adept at controlling vehicle speed simply by using the accelerator to speed up and using regen to slow down without ever touching the brakes. It’s a simpler way to drive and you will find your brakes lasting a lot longer. I have over 100,000 miles on my Model S and it still has the original brake pads.

There are a couple of caveats to remember with regen:

  • If you have charged your battery to 100%, regen may be temporarily limited because there is no place for the generated electricity to go. The result is the car the car may not slow down as quickly you you might expect. If there is limited regen, a graphic indicator will show up to let you know:
    • Pre-AP Model S: a radial dotted one (like a clock hand) will appear to show the regen limit
    • AP Model S and all Model X: the arc of the energy app will turn from solid to dotted to show the regen limit
    • Model 3: a dashed line will appear on the energy bar
  • On cold mornings, regeneration may also be temporarily limited until the battery pack has had a chance to warm up. The car will indicate limited regen in the same manner as listed above.
  • If you are driving in snowy, slippery road conditions, some owners find temporarily setting regen to low gives them more predictable handling.


Even if you are not usually a lead foot, it is fun to occasionally let the car run free. There are a couple of things to bear in mind:

  • You may not fully appreciate how quickly you can get going and the electric drive lacks the usual cues, so be careful you don’t end up testing the understand of your local police. :). There were a few times early on when I went to blip the accelerator to ease past someone and found myself slingshotting past them instead.
  • Between the jackrabbit acceleration and the regeneration you can actually kinda make your passengers seasick, so practice transitioning smoothly from speeding up to slowing down. Outside of happier passengers, this will help you improve you overall driving efficiency and range. You can use the energy app as a visual reminder of this.


Your Tesla is simple–put it in Drive to go forward, put it in Reverse to go backward and put it into Park to, well, park. The car does not actually have a transmission, all you are really doing is changing the direction the electricity flows through the motor. One thing to be aware of is the car will free roll if you are not pressing on the accelerator. So, if you were to approach a stop light on a slight incline and used regeneration-braking to slow down, at some point the car will start rolling back if you don’t apply the brakes or keep the accelerator slightly depressed. Vehicles with AutoPilot have a “vehicle hold” feature to help with this. When you press and hold the brake, vehicle hold will engage, the car will electrically keep the brakes applied (even if you life your foot of the brake pedal) and a “H” in a circle will light up in the instrument cluster/touchscreen to notify you the feature is engaged. To relate the vehicle hold, tap the accelerator to move or tap the brake to release the brakes (remember, if you are an incline, the car will roll). For pre-AutoPilot cars, you need to manually keep your foot on the brakes or a bit of pressure on the accelerator.


Charging can seem daunting because its new and different and electricity can certainly seem a bit scary. But, as you will see, it will quickly become second nature.

A Quick Word About Safety

An electric car charger is properly termed Electric Vehicle Supply Equipment, or EVSE (you know an engineer had a hand in naming that). The reason for the fancy name is that your charging cable is more than just a big fancy extension cord. The biggest difference is that the exposed end of an extension cord is energized as soon as you plug it in. All EVSEs are designed to not energize the charging handle until it is plugged into the car and the EVSE has determined the connection is working properly.

If you look at the end of the Tesla plug, you will see two big pins, one medium pin and two small pins. When you plug you charger into your car, the car and the charger use these two small pins to communicate with each other using low voltage signals. The two big high voltage pins are only energized once the car and the charger have established a connection, exchanged information about each others capabilities and decided everything is cool. While there are a number of different EV charging standards out there, they all follow a similar approach to electrical safety. As long the charging gear is not physically damaged, it is perfectly safe to charge in the rain, etc. If you do see physical damage to the equipment, cable or handle, if its a built charger, three should be an 800 support number on the charger–call the company and let them know. If the damage is on your charger at home, flip the appropriate breaker off and call the manufacturer and/or whoever installed the gear for you.

How to Charge

Charging is going to seem very similar to pumping gas at a self-serve pump, but it is still covering the steps:

  • Pull up or back up to the charger–your charge port is on the driver’s side in the back. If you are pulling into a Tesla Supercharger location and all the stalls are full, look for other Teslas lined up somewhere or if there if no one else, start you own line. Note that some busy locations will have a valet that will guide you and do traffic management.
  • Pop open the charge port–depending on the vehicle you have this can by done from the main display, by pressing on the charge port door, or double-clicking the “trunk” on the key fob
  • Depending on where you are charging, you might need to swipe a credit card or other membership card to activate the charger–one of the other chapters deals with charging options on while on the road
  • Push the charger handle into the charge port until you hear a click and charge port light turns green. If the light turns yellow or red, you might not have pushed the charging handle in far enough or the charger and the car might have problem communicating. You can try moving to another charger or if there is a support number on the charger, call them–often they can diagnose and fix problems remotely
  • Depending on where you are charging you might also need to use an adapter–see this chapter
  • Watch the electrons flow into your battery. At this point, the charger handle is locked into your car, so you can lock the car and go grab some coffee, etc.

  • Typical charging screens (Details vary based on vehicle, how you have set up your car and what kind of charger you are connected to)
  • When you are ready to leave, stop charging by pressing the stop charging button on the main display or pressing the button/trigger on the charging handle (exact location will vary). You will hear a clunk, which is the car releasing the charger handle.
  • Pull the charging handle out and hang it back up on the charger and put away any adapters you might have used.
  • Close the charger cover if you don’t have an auto-closing cover and get back on the road.

Next I would suggest reading Charging at Home and Charging on the Road to get more detail on the charging options you may encounter. Really, the best thing you can do is go out and drive. Outside of being fun, the more practice you get, the quicker these skills will become second nature.

Sharing the Road

EVs are especially quiet, so be careful around pedestrians and bicyclists as they may not be able to hear you, especially at low speeds in areas such as driveways, residential streets and parking lots. At higher speeds, tire noise, wind noise, etc start to kick in and its less of an issue.
