BMW X3 Owners Manual: Braking safely

Your vehicle is equipped with ABS as a standard feature.

Applying the brakes fully is the most effective way of braking in situations needed.

Steering is still responsive. You can still avoid any obstacles with a minimum of steering effort.

Pulsation of the brake pedal and sounds from the hydraulic circuits indicate that ABS is in its active mode.

In certain braking situations, the perforated brake discs can cause functional problems.

However, this has no effect on the performance and operational reliability of the brake.

Objects within the range of movement of the pedals

No objects in the area around the pedals

Keep floor mats, carpets, and any other objects out of the pedal area; otherwise, the function of the pedals could be impeded while driving and create the risk of an accident.

Do not place additional floor mats over existing mats or other objects.

Only use floor mats that have been approved for the vehicle and can be properly attached to floor.

Ensure that the floor mats are securely fastened again after they were removed for cleaning, e.g.

Driving in wet conditions When roads are wet, salted, or in heavy rain, press brake pedal ever so gently every few miles.

Ensure that this action does not endanger other traffic.

The heat generated in this process helps dry the brake discs and pads.

In this way braking efficiency will be available when you need it.


Avoid stressing the brakes

Avoid placing excessive stress on the brake system. Light but consistent brake pressure can lead to high temperatures, brakes wearing out and possibly even brake failure.

Do not drive in neutral

Do not drive in neutral or with the engine stopped, as doing so disables engine braking.

In addition, steering and brake assist are unavailable with the engine stopped.

Drive long or steep downhill gradients in the gear that requires least braking efforts. Otherwise the brakes may overheat and reduce brake efficiency.

You can increase the engine's braking effect by shifting down, going all the way to first gear, if needed.

Brake disc corrosion Brake disc corrosion and contamination of the brake pads are favored by:

  • Low mileage.
  • Extended periods when the vehicle is not used at all.
  • Infrequent use of the brakes.

Corrosion will built up when the maximum pressure applied to the brake pads during braking is not reached - thus discs don't get cleaned.

Corrosion buildup on the brake discs will cause a pulsating effect on the brakes in their response - generally that cannot be corrected.

Condensation under the parked vehicle

When using the automatic climate control, condensation water develops collecting underneath the vehicle.

These traces of water under the vehicle are normal.
