Mastering the heat wave with Tesla: You need to know these 11 tricks

A hot summer day in a Tesla can quickly become a challenge – the interior feels like an oven, the air conditioning runs hot, and the battery suffers. However, with targeted vehicle functions and smart tricks, the heat can be effectively tamed.

Heat in the Tesla: Is the glass roof the culprit?

During the summer months, Tesla Model Y, 3 and similar vehicles are particularly affected by the warm temperatures – the reason being the glass roof.

In extreme heat, especially when stationary, the interior heats up extremely – often well over 60 °C – putting a strain not only on the air conditioning but also on the battery.

Continuous operation of the A/C while stationary consumes significant amounts of energy and can noticeably reduce the vehicle's range. . The optional "cabin overheating protection" feature does have a cooling effect, but it consumes a lot of energy.

Cleverly utilize Tesla vehicle features

• Actively pre-cool using climate control from the app

The Tesla app allows you to pre-cool the vehicle before getting in – for up to two hours and up to a charge level of 20%.. The interior and, if applicable, the battery are cooled down in this way, without wasting energy while driving.

• Use the "Auto" mode of the automatic climate control

The "Auto" mode automatically adjusts temperature, air distribution and fan speed – similar to a home thermostat control.. In summer, the fan speed increases as soon as cooling is needed and decreases as soon as the target temperature is reached – perfect for comfort and efficiency.

• Use cabin overheating protection in a targeted manner

This function keeps the temperature below approximately 42°C when stationary in high ambient temperatures. However, it does consume battery power. Tip: Only activate it if you expect to be parked for an extended period and have no access to shade.

• Park in the shade and pre-cool the battery.
  

Park in the shade whenever possible and activate the air conditioning briefly before switching off the engine to pre-cool the battery. This reduces charging losses during the next start and has a positive effect on range and cooling performance.

• Allow the heat pump to operate optimally

Models with heat pump (Model Y, Model 3 from 2021 onwards) cool particularly efficiently – but only if the airflow is not blocked.

Therefore, regularly remove coarse dirt from the air vents under the frunk cover and set the air conditioning to "Auto" instead of manually selecting high fan speeds. This allows the heat pump to operate in its optimal range and save energy.

• Use the "keep temperature" function

If you are only going shopping briefly, activate the "keep temperature" function before getting out of the car.

Your Tesla keeps the air conditioning active, maintaining a pleasantly cool interior. This means you can get into a pre-conditioned vehicle – without the air conditioning having to work against overheated air.

Accessories that really help

1. Roof sun protection: Heat break directly under the glass roof

The huge glass roof is a real eye-catcher in every Tesla – but also a real weak point in summer. Without protection, the interior heats up noticeably despite the tint.Teslabs' perfectly fitting roof sunshade blocks a large portion of the incoming radiation without completely sacrificing the airy look.

The result: noticeably lower temperatures, reduced air conditioning consumption, and greater comfort for all passengers. Thanks to the clip-on mounting system, the sunshade is quick to install and just as easy to remove when needed.

The reflective layer on the top acts like a heat shield directly under the glass roof. The effect is clearly measurable, especially during extended drives in the sun or when parked without shade. For those who drive a lot in the summer, this accessory ensures consistently more comfortable conditions inside the vehicle – without any modifications to the vehicle itself.

2. Windshield sunshade: Effective protection

The windshield is the largest surface through which direct sunlight enters the Tesla – especially when stationary, this quickly leads to a build-up of heat.

Teslabs' windshield sunshade blocks exactly that: With its multi-layered structure, it reflects sunlight and significantly reduces heat buildup in the interior. This not only protects the air conditioning system but also sensitive materials like the dashboard and steering wheel.

The sunshade can be positioned behind the windshield in seconds and fits perfectly thanks to its precise design. A stable yet flexible construction ensures a secure hold – without ripples or sagging. When folded, it fits easily into the trunk or a side pocket.

Ideal for hot days in the parking lot or extended periods of inactivity during summer holidays. Those who take smart precautions will get into a noticeably cooler car.

3. Children's sun protection: Shade where it's most needed.

Especially in the back seat, direct sunlight often hits the youngest children – and this can continue for many kilometers. Teslabs' child sunshades provide a targeted solution.

They cover the rear side windows and offer reliable protection from heat and glare without completely obstructing the view. This ensures continued driving comfort even in intense sunlight – for children and adults alike.

The precisely fitting shades can be mounted without tools using suction cups and stay securely in place. Thanks to the tightly woven fabric, sunlight is filtered and UV radiation is effectively reduced.

4. Cabin filter mesh: Heat protection begins with the airflow

What many people don't know: A clean and protected air intake not only ensures better air quality, but also a more efficient air conditioning system.

The Teslabs cabin filter net protects the air conditioning intake duct from leaves, dirt and insects – thus preventing heat sources or odors from becoming trapped in the system.

This is a real advantage, especially in summer when pollen and dust are in the air. The air conditioner can breathe more freely and operates more quietly and efficiently.

The net is made of a robust, fine-mesh fabric and is permanently attached above the intake duct using a click mechanism. Once installed, it performs its function discreetly but effectively.

It extends the lifespan of cabin air filters and reduces the risk of unpleasant odors. Anyone wanting to do something good for their air conditioning system – especially in summer – will find this accessory to be the right choice.

5. Change the cabin air filter: Fresh air, even in summer heat

Especially in summer, clean air in the vehicle is crucial – because pollen, dust, and exhaust fumes increase significantly in hot weather. Teslabs cabin air filters with activated carbon technology filter these airs. Fine dust, gaseous pollutants such as nitrogen oxides and unpleasant odors.

This protects health and reduces the strain on the air conditioning system through improved airflow. Allergy sufferers in particular benefit noticeably from the high filter performance.

The filters are designed to fit the Tesla Model 3 and Y perfectly and can be replaced in just a few minutes. The activated carbon layer provides extra freshness – especially in hot summer city air. Those who regularly drive in stop-and-go traffic or are sensitive to outside air will find these filters offer a more comfortable and healthier driving experience.
