BMW X3 Owners Manual: Diesel particulate filter

The diesel particulate filter collects soot particles and burns them periodically at high temperatures.

During several minutes of cleaning the following may occur:

• Temporarily, the engine may run less smoothly.
• Noises and a slight amount of smoke coming from the exhaust until shortly after the engine is shut down.
• A somewhat higher engine speed is necessary to reach usual performance.

Mobile communication devices in the vehicle

Mobile communication devices in the vehicle

It is not recommended to use mobile phones, such as mobile phones, in the vehicle interior without a direct connection to an external aerial.

Otherwise, the vehicle's electronics and mobile communication devices can interfere with each other. In addition, there is no assurance that the radiation generated during transmission will be conducted away from the vehicle interior.

Hydroplaning

Hydroplaning

When driving on wet or slushy roads, reduce your speed to prevent hydroplaning.

On wet or slushy roads, a wedge of water can form between the tires and road surface.

This phenomenon is referred to as hydroplaning.

It is characterized by a partial or complete loss of contact between the tires and the road surface, ultimately undermining your ability to steer and brake the vehicle.

Driving through water

Observe water level and speed

Do not exceed the maximum water level and maximum speed; otherwise, the vehicle's engine, the electrical systems and the transmission may be damaged.

Drive though calm water only and only if it is not deeper than 19.6 inches/50 cm and at this height, no faster than walking speed, up to 3 mph/5 km/h.
