BMW X5: Messages - Tire pressure monitor

Messages: for tires without special approval

General information

A low tire inflation pressure may cause the DSC Dynamic Stability Control to be switched on.

Safety information

Warning

A damaged regular tire with low or missing tire inflation pressure impacts handling, such as steering and braking response. Run-flat tires can maintain limited stability. There is a risk of accident. Do not continue driving if the vehicle is equipped with normal tires. Follow the information on run-flat tires and continued driving with these tires.

If a tire inflation pressure check is required

Message

An icon with a Check Control message appears on the Control Display.

Inflation was not carried out according to specifications, for instance when the tire has not been sufficiently inflated or in the case of a natural steady tire pressure loss.

Measure

Check the tire pressure and correct as needed.

If the tire inflation pressure is too low

Message

A yellow warning light is illuminated in the instrument cluster.

In addition, an icon with a Check Control message appears on the Control Display.

There is a tire pressure loss.

Measure

1. Reduce the vehicle speed. Do not exceed a speed of 80 mph/130 km/h.

2. At the next opportunity, for instance at a filling station, check the tire inflation pressure in all four tires and correct if necessary.

If there is a significant tire pressure loss

Message

A yellow warning light is illuminated in the instrument cluster.

In addition, an icon with the affected tire appears in a Check Control message on the Control Display.

There is a flat tire or a major tire pressure loss.

Measure

1. Reduce your speed and stop cautiously.

Avoid sudden braking and steering maneuvers.

2. Check whether the vehicle is fitted with normal tires or run-flat tires.

Run-flat tires are labeled with a circular icon containing the letters RSC marked on the tire sidewall.

3. Read the description on What to do in case of a flat tire.

If a tire inflation pressure check is required

Message

An icon with a Check Control message appears on the Control Display.

Inflation was not carried out according to specifications, e.g., the tire has not been sufficiently inflated.

The system has detected a wheel change, but no reset was done.

The tire inflation pressure has fallen below the level of the last reset.

No reset was performed for the system.

The system issues a warning based on the tire inflation pressures stored during the last reset.

Measure

1. Check the tire pressure and correct as needed.

2. Perform a system reset.

Run-flat tires.

Actions in the event of a flat tire

Normal tires

1. Identify the damaged tire.

Check the tire pressure in all four tires, for instance using the tire pressure display of a flat tire kit.

For tires with special approval: when the tire pressure in all four tires is correct, the Tire Pressure Monitor may not have been reset. In this case, perform the reset.

If tire damage cannot be found, contact a dealer's service center or another qualified service center or repair shop.

2. Repair the flat tire, e.g., with a flat tire kit or by changing the wheel.

Use of sealing compound, for instance from the flat tire kit, may damage the wheel electronics.

Have the electronics replaced at the next opportunity.

Runflat tires

Safety information

Warning

The vehicle handles differently when a run-flat tire has insufficient or no tire pressure; for instance, reduced lane stability when braking, braking distances are longer and the self-steering properties will change. There is a risk of accident.

Drive moderately and do not exceed a speed of 50 mph/80 km/h.

Warning

Heavy trailers can start swinging when continuing to drive with a flat tire. There may be a risk of accident or risk of damage to property. Do not exceed a speed of 35 mph/60 km/h when driving with a trailer and a flat tire. Immediately brake in the case of swinging. Apply necessary steering corrections as carefully as possible.

Maximum speed

You may continue driving with a damaged tire at speeds up to 50 mph/80 km/h.

Continued driving with a flat tire

Follow the following when continuing to drive with a damaged tire:

1. Avoid sudden braking and steering maneuvers.

2. Do not exceed a speed of 50 mph/80 km/h.

3. Check the tire inflation pressure in all four tires at the next opportunity.

Possible driving distance with a depressurized tire

The distance for which it may be possible to drive safely varies depending on how the vehicle is loaded and used, e.g., speed, road conditions, outside temperature. The driving distance may be less but may also be more if an economical driving style is used.

If the vehicle is loaded with an average weight and used under favorable conditions, the distance for which it may be safe to drive may be up to 50 miles/80 km.

Vehicle handling with damaged tires

Vehicles driven with a damaged tire will handle differently, potentially leading to conditions such as the following:

• Greater likelihood of skidding of the vehicle.
• Longer braking distances.
• Changed self-steering properties.

Modify your driving style. Avoid abrupt steering maneuvers or driving over obstacles, for instance curbs or potholes.

Final tire failure

Vibrations or loud noises while driving can indicate the final failure of a tire.

Reduce speed and stop; otherwise, pieces of the tire could come loose and cause an accident.

Do not continue driving. Contact a dealer's service center or another qualified service center or repair shop.
