When driving on wet or slushy roads, 
reduce road speed. If you do not, a wedge 

of water can form between tires and road sur-
face. This phenomenon is referred to as hydro-
planing, and 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.

<

The risk of hydroplaning increases as the tread 
depth of the tires decreases, refer also to Mini-
mum tread depth on page

.

Do not drive through water on the road if it 
is deeper than 20 in/50 cm, and then only 

at walking speed at the most. Otherwise, the 
vehicle's engine, the electrical systems and the 
transmission may be damaged.

<

The starting assistant enables you to start off 
conveniently on slopes. The parking brake is 
not required for this purpose.

1.

Hold the vehicle with the footbrake.

2.

Release the footbrake and immediately 
drive off quickly.

The starting assistant holds the vehicle 
for approx. 2 seconds after releasing the 

footbrake. Depending on the load, the vehicle 
may also roll back slightly during this time. 
After releasing the footbrake, immediately start 
quickly, otherwise the starting assistant no 
longer holds the vehicle after approx. 2 seconds 
and it begins to roll back.

<

Your BMW is equipped with ABS as a standard 
feature. In situations that require it, it is best to 
brake with full force. Since the vehicle maintains 
steering responsiveness, you can still avoid 
possible obstacles with a minimum of steering 
effort.
Pulsation of the brake pedal, combined with 
sounds from the hydraulic circuits, indicate that 
ABS is in its active mode.

Do not drive with your foot resting on the 
brake pedal. Even light but consistent 

pedal pressure can lead to high temperatures, 
brake wear and possibly even brake failure.

<

When roads are wet or there is heavy rain, 
briefly exert gentle pressure on the brake pedal 
every few miles. Monitor traffic conditions to 
ensure that this maneuver does not endanger 
other road users. The heat generated in this 
process helps dry the pads and rotors to ensure 
that full braking efficiency will then be available 
when you need it.

To prevent overheating and the resulting 
reduced efficiency of the brake system, 

drive long or steep downhill gradients in the 
gear in which the least braking is required. Even 
light but consistent pressure on the brake pedal 
can lead to high temperatures, brake wear and 
possibly even brake failure.

<

The braking effect of the engine can be further 
increased by downshifting in the manual mode 
of the automatic transmission, if necessary into 
first gear, refer to page

. This prevents an 

excessive strain on the brakes.

Do not drive in idle or with the engine 
stopped, otherwise there will be no 

engine braking action or support of the braking 
force and steering.
Never allow floor mats, carpets or any other 
objects to protrude into the area of movement 
of the pedals and impair their operation.

<

When the vehicle is driven only occasionally, 
during extended periods when the vehicle is not 
used at all, and in operating conditions where 
brake applications are less frequent, there is an 
increased tendency for corrosion to form on 
rotors, while contaminants accumulate on the 
brake pads. This occurs because the minimum 
pressure which must be exerted by the pads 
during brake applications to clean the rotors is 
not reached.
