What should I do if my vehicle key battery is dead?

If the LED in the key does not blink when you press a button, the battery is empty and must be replaced. Remove the emergency key, insert it diagonally into the opening on the battery carrier, press it in the arrow direction to release the internal latch, remove the battery cover, insert the new battery with the "+" sign facing up, and close the battery compartment. The replacement battery must match the original specification.

How do I unlock my vehicle if I'm inside and accidentally press the lock button on the key?

If you are inside the vehicle, do not lock or unlock using the key buttons as you could trigger the theft alarm. Instead, press the unlock button on the door panel to disarm the alarm.

What are the safety warnings for the tailgate?

You must ensure no one is in the tailgate's functional area, especially near hinges, upper and lower edges, and surrounding edges to avoid crush injuries. Always verify the tailgate locks fully after closing to prevent it from opening during driving. Never drive with the tailgate ajar or open as exhaust fumes could enter the cabin, causing poisoning. If a roof rack is mounted, the tailgate may not fully open or may drop due to extra weight—support it or remove the cargo. With Safelock engaged, doors and windows cannot be opened from inside, creating a life-threatening situation if anyone is locked inside.

What is the Audi connect key and how do I use it?

The Audi connect key allows you to unlock, lock, and start your vehicle using a compatible mobile device with Android operating system running the myAudi App. To use it, you must register at my.audi.com, have the myAudi App installed, and have the service activated in the MMI. A main user must be designated. You can grant the key to other users by providing a 6-digit security code obtained from the vehicle's MMI. Hold the mobile device mid-height at the driver door handle to unlock or lock the vehicle. The key can be de-activated at any time through the MMI or myAudi App.

How do I open the tailgate with a foot gesture?

For vehicles with sensor-controlled tailgate, carry your comfort key and ensure the ignition is off. Stand centered behind the tailgate and move your foot in one smooth motion under the rear bumper forward and back without touching it, maintaining a safe stance. If the system recognizes the motion, the tailgate will open. The automatic operation stops if you repeat the gesture or if an obstacle blocks it. This function may be limited or unavailable if you stand too close or too far from the bumper, the tailgate was just opened/closed, or if radio signals are disrupted by other transmitters.

What should I know about the emergency key inside my vehicle key?

Your vehicle key contains an integrated emergency key. To remove it, press the release button and pull the key out. The emergency key allows you to: switch the front passenger airbag on/off (page 91), lock/unlock the glove compartment, perform emergency door lock/unlock (page 47), lock/unlock the rear seat backrest if equipped with fold-down seats (page 102), and perform emergency tailgate unlock (page 58).

What is the maximum power consumption allowed for devices connected to the 12-volt sockets?

The total power consumption at the 12-volt sockets must not exceed 120 watts. Multiple devices should not be connected simultaneously to the vehicle's sockets. The 12-volt sockets are located in the front center console, rear, and side trim in the cargo area.

What safety precautions must I follow when using the cigarette lighter?

The cigarette lighter only functions when the ignition is switched on. Improper use can cause serious injuries or fire. Children must never be left unattended in the vehicle with the key, as there is a risk of injury.

Can I place hot drinks in the cup holders while driving?

No. The manual states: Do not place hot drinks in the cup holders while the vehicle is in motion, as hot drinks could spill and cause injury. Additionally, do not use hard drinking containers such as glass or porcelain, as you could be injured in an accident.

What weight limit applies to objects placed on the rear seat shelf area?

No heavy or hard objects should be placed on the shelf area behind the rear headrests, and no animals should be transported there. Objects in this location pose an injury hazard during sudden driving maneuvers, braking, or accidents.

How should I properly load the cargo area for optimal vehicle handling?

Distribute the load evenly in the cargo area and stow heavy luggage as far forward as possible in the cargo area. Secure luggage pieces with non-elastic tie straps at the tie-down anchors. Never exceed the permissible axle loads and total vehicle weight. Heavy cargo shifts the center of gravity and affects handling, so adjust driving style and speed accordingly.

What is the maximum weight for objects stored under the double load floor?

Objects stored under the double load floor must not exceed 7.5 kg maximum, and must not occupy more than two-thirds of the height of the raised load floor. Objects must be secured appropriately.

Frequently asked questions(12)

What should I do if my vehicle key battery is dead?: If the LED in the key does not blink when you press a button, the battery is empty and must be replaced. Remove the emergency key, insert it diagonally into the opening on the battery carrier, press it in the arrow direction to release the internal latch, remove the battery cover, insert the new battery with the "+" sign facing up, and close the battery compartment. The replacement battery must match the original specification.
How do I unlock my vehicle if I'm inside and accidentally press the lock button on the key?: If you are inside the vehicle, do not lock or unlock using the key buttons as you could trigger the theft alarm. Instead, press the unlock button on the door panel to disarm the alarm.
What are the safety warnings for the tailgate?: You must ensure no one is in the tailgate's functional area, especially near hinges, upper and lower edges, and surrounding edges to avoid crush injuries. Always verify the tailgate locks fully after closing to prevent it from opening during driving. Never drive with the tailgate ajar or open as exhaust fumes could enter the cabin, causing poisoning. If a roof rack is mounted, the tailgate may not fully open or may drop due to extra weight—support it or remove the cargo. With Safelock engaged, doors and windows cannot be opened from inside, creating a life-threatening situation if anyone is locked inside.
What is the Audi connect key and how do I use it?: The Audi connect key allows you to unlock, lock, and start your vehicle using a compatible mobile device with Android operating system running the myAudi App. To use it, you must register at my.audi.com, have the myAudi App installed, and have the service activated in the MMI. A main user must be designated. You can grant the key to other users by providing a 6-digit security code obtained from the vehicle's MMI. Hold the mobile device mid-height at the driver door handle to unlock or lock the vehicle. The key can be de-activated at any time through the MMI or myAudi App.
How do I open the tailgate with a foot gesture?: For vehicles with sensor-controlled tailgate, carry your comfort key and ensure the ignition is off. Stand centered behind the tailgate and move your foot in one smooth motion under the rear bumper forward and back without touching it, maintaining a safe stance. If the system recognizes the motion, the tailgate will open. The automatic operation stops if you repeat the gesture or if an obstacle blocks it. This function may be limited or unavailable if you stand too close or too far from the bumper, the tailgate was just opened/closed, or if radio signals are disrupted by other transmitters.
What should I know about the emergency key inside my vehicle key?: Your vehicle key contains an integrated emergency key. To remove it, press the release button and pull the key out. The emergency key allows you to: switch the front passenger airbag on/off (page 91), lock/unlock the glove compartment, perform emergency door lock/unlock (page 47), lock/unlock the rear seat backrest if equipped with fold-down seats (page 102), and perform emergency tailgate unlock (page 58).
What is the maximum power consumption allowed for devices connected to the 12-volt sockets?: The total power consumption at the 12-volt sockets must not exceed 120 watts. Multiple devices should not be connected simultaneously to the vehicle's sockets. The 12-volt sockets are located in the front center console, rear, and side trim in the cargo area.
What safety precautions must I follow when using the cigarette lighter?: The cigarette lighter only functions when the ignition is switched on. Improper use can cause serious injuries or fire. Children must never be left unattended in the vehicle with the key, as there is a risk of injury.
Can I place hot drinks in the cup holders while driving?: No. The manual states: Do not place hot drinks in the cup holders while the vehicle is in motion, as hot drinks could spill and cause injury. Additionally, do not use hard drinking containers such as glass or porcelain, as you could be injured in an accident.
What weight limit applies to objects placed on the rear seat shelf area?: No heavy or hard objects should be placed on the shelf area behind the rear headrests, and no animals should be transported there. Objects in this location pose an injury hazard during sudden driving maneuvers, braking, or accidents.
How should I properly load the cargo area for optimal vehicle handling?: Distribute the load evenly in the cargo area and stow heavy luggage as far forward as possible in the cargo area. Secure luggage pieces with non-elastic tie straps at the tie-down anchors. Never exceed the permissible axle loads and total vehicle weight. Heavy cargo shifts the center of gravity and affects handling, so adjust driving style and speed accordingly.
What is the maximum weight for objects stored under the double load floor?: Objects stored under the double load floor must not exceed 7.5 kg maximum, and must not occupy more than two-thirds of the height of the raised load floor. Objects must be secured appropriately.
