Audi Q7 (4M) 2016-2022 Owner's Manual: Tires and vehicle load limits

There are limits to the amount of load or weight that any vehicle and any tire can carry. A vehicle that is overloaded will not handle well and is more difficult to stop.

Overloading can not only lead to loss of vehicle control, but can also damage important parts of the vehicle and can lead to sudden tire failure, including a blowout and sudden deflation that can cause the vehicle to crash.

Your safety and that of your passengers also depends on making sure that load limits are not exceeded.

Vehicle load includes everybody and everything in and on the vehicle. These load limits are technically referred to as the vehicle's Gross Vehicle Weight Rating ("GVWR").

The "GVWR" includes the weight of the basic vehicle, all factory installed accessories, a full tank of fuel, oil, coolant and other fluids plus maximum load. The maximum load includes the number of passengers that the vehicle is intended to carry ("seating capacity") with an assumed weight of 150 lbs. (68 kg) for each passenger at a designated seating position and the total weight of any luggage in the vehicle. If you tow a trailer, the weight of the trailer hitch and the tongue weight of the loaded trailer must be included as part of the vehicle load.

The Gross Axle Weight Rating ("GAWR") is the maximum load that can be applied at each of the vehicle's two axles.

The fact that there is an upper limit to your vehicle's Gross Vehicle Weight Rating means that the total weight of whatever is being carried in the vehicle (including the weight of a trailer hitch and the tongue weight of the loaded trailer) is limited. The more passengers in the vehicle or passengers who are heavier than the standard weights assumed mean that less weight can be carried as luggage.

The Gross Vehicle Weight Rating and the Gross Axle Weight Rating are listed on the safety compliance sticker on the driver's side Bpillar respectively on the front end of the driver's door.

WARNING

Overloading a vehicle can cause loss of vehicle control, a crash or other accident, serious personal injury, and even death.

Determining correct load limit

Use the example below to calculate the total weight of the passengers and luggage or other things that you plan to transport so that you can make sure that your vehicle will not be overloaded.

Steps for Determining Correct Load Limit

1. Locate the statement "THE COMBINED WEIGHT OF OCCUPANTS AND CARGO SHOULD NEVER EXCEED XXX KG OR XXX LBS" on your vehicle's placard (tire inflation pressure label) fig. 173.

2. Determine the combined weight of the driver and passengers that will be riding in your vehicle.

3. Subtract the combined weight of the driver and passengers from "XXX" kilograms or "XXX" pounds shown on the sticker fig. 173.

4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the "XXX" amount equals 1400 lbs. and there will be five 150 lbs. passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs.

(1400-750 (5 x 150) = 650 lbs.)

5. Determine the combined weight of luggage and cargo being loaded on the vehicle.

That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4.

6. If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle.

Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle.

Wheel bolts and rims

Wheel bolts

Wheel bolts must be clean and loosen/tighten easily.

Rims

Rims with a bolted rim ring* or with bolted wheel covers* consist of multiple pieces. These components were bolted together using special bolts and a special procedure. You must not repair or disassemble them .

WARNING

Wheel bolts that are tightened or repaired incorrectly can become loose and result in loss of vehicle control, which increases the risk of an accident. For the correct tightening specification.

Loose wheel warning

Applies to: vehicles with loose wheel warning

Within the limits of the system, the loose wheel warning in the instrument cluster warns you if one or more wheels are loose.

Using the ABS sensors, the loose wheel warning system compares the vibration characteristics of the individual tires. If one or more wheels are loose, it will be indicated in the instrument cluster display with the indicator light and a message.

If only one wheel is affected, the location of that wheel will be indicated.

Messages

Wheel bolts loose. Please safely stop the vehicle and check all wheel bolts!

Loose wheel warning for at least one wheel .

Check the wheel bolts on all wheels with the wheel wrench (vehicle tool kit). Have the tightening specification checked as soon as possible with a torque wrench. Drive carefully until then. For the correct tightening specification, see Finishing.

Wheel assessment active. Please continue driving carefully

After this message appears and you have checked the wheel bolts, the assessment phase begins when the vehicle is in motion. This may take several minutes.

Loose wheel warning: malfunction! See owner's manual

There is a system malfunction. Drive immediately to an authorized Audi dealer or authorized Audi Service Facility to have the malfunction repaired.

WARNING

Wheel bolts that are tightened incorrectly can become loose and result in loss of vehicle control, which increases the risk of an accident.
