7 Hidden Car Features You May Not Know You Have

Modern cars are packed with technology, but many drivers use only a fraction of what their vehicle can actually do. Beyond the obvious touchscreen, parking sensors and cruise control, manufacturers often include clever functions that are hidden inside key fobs, menus, mirrors and vehicle settings.

Some are designed for convenience, others for safety — and a few can be particularly useful for drivers in the UAE and GCC.

Here are seven features worth checking on your own car.

1. Open the Windows From Your Key Fob

On some vehicles, holding a particular button or sequence on the remote key can lower the windows before you even enter the car.

This can be especially useful when a vehicle has been parked outside during a hot UAE afternoon, allowing some of the trapped heat to escape before you get inside.

The exact operation varies by manufacturer and model. For example, some vehicles require the unlock button to be pressed and held. Always check your owner’s manual rather than assuming your car supports the function.

Consumer Reports identifies remote window opening as one of the lesser-known functions available on a number of modern key fobs.

2. Remote Cabin Cooling

Connected-car apps and remote-start systems are making it possible to prepare the cabin before entering.

Depending on the vehicle, drivers may be able to remotely start climate control or precondition the cabin from their smartphone.

For UAE motorists, this is far more than a novelty. CarBook recently highlighted remote engine start and climate-control functionality among the connected features available on the 2026 Nissan Pathfinder.

3. Automatic Brake Hold

If your car has an Auto Hold button, it can make traffic significantly more comfortable.

Once activated on compatible vehicles, the system can keep the brakes applied after the vehicle comes to a complete stop, allowing the driver to remove their foot from the brake pedal.

It can be particularly convenient in slow-moving urban traffic and at long traffic lights.

4. A Mirror That Helps Reduce Glare

Many modern vehicles feature an auto-dimming rear-view mirror.

Sensors detect bright light coming from vehicles behind and automatically darken the mirror to reduce glare.

It is easy to overlook because there may be very little driver interaction required, but it can make night driving considerably more comfortable.

5. Hidden Emergency Key Inside the Key Fob

Smart keys have largely eliminated the traditional ignition key — but that doesn’t necessarily mean the physical key has disappeared.

Many key fobs contain a small mechanical emergency key hidden inside the casing.

Depending on the vehicle, it can be used to unlock the driver’s door if the key-fob battery is depleted.

The procedure varies significantly between vehicles, so knowing how your particular system works before the battery dies can save considerable frustration.

6. Adjustable Boot Opening Height

Powered tailgates are convenient, but opening one fully inside a low garage can create an unpleasant surprise.

Some vehicles allow owners to programme the maximum opening height of the powered tailgate.

Set it once and the boot can stop at the preferred position each time it opens.

It is a simple feature, but a very practical one for SUVs frequently parked in underground garages.

7. Your Car May Be Updating While You Sleep

Increasingly, modern connected vehicles support over-the-air (OTA) software updates.

Much like a smartphone, compatible cars can receive software improvements remotely instead of requiring a workshop visit for every update.

Depending on the manufacturer and vehicle architecture, OTA updates can affect areas such as infotainment, navigation, voice assistants, energy management and other software-controlled functions.

CarBook recently explored how over-the-air updates are changing modern car ownership.

Your Owner’s Manual May Hold More Surprises

The increasingly digital nature of modern cars means there may be useful functions owners never discover.

The important point is that features vary by manufacturer, model, market and trim level. A button sequence that works on one car may do absolutely nothing on another.

Spend a few minutes exploring your vehicle settings, manufacturer’s app and owner’s manual. You may discover that the car you’ve been driving every day can do much more than you realised.
