Driving hints
▷ Drive through water at no faster than
5 km/h, approximately 3 mph.
Safety note
NOTE
Driving through excessively deep water
too fast can result in water entering the engine
compartment, electrical system or transmis‐
sion. There is a danger of damage to property.
When driving through water, do not exceed the
maximum specified water depth and maximum
fording speed.◀
Safe braking
The vehicle is equipped with ABS as standard.
Perform full braking in situations that require it.
The vehicle can be steered. Any obstacles can
be avoided by performing steering movements
as smoothly as possible.
A pulsing of the brake pedal shows that ABS is
regulating.
In certain braking situations, the perforated
brake discs can cause functional noise. Func‐
tional noises have no effect on the efficiency
and operational safety of the brakes.
Objects in the range of movement of
the pedals and in the footwell
WARNING
Objects in the driver's footwell can re‐
strict the pedal travel, or block a pedal that has
been pressed. There is a danger of accidents.
Stow items in the vehicle so that they are se‐
cure and cannot get into the driver's footwell.
Only use floor mats that are appropriate for the
vehicle and can be securely fastened to the
floor. Do not use any loose floor mats, and do
not place several floor mats on top of one an‐
other. Make sure that there is sufficient space
for the pedals. Ensure that the floor mats are
securely reattached after having been re‐
moved, for example for cleaning.◀

Wet roads
In damp weather, if road grit has been spread
or there is heavy rain, apply the brakes lightly
every few kilometres/miles.
In doing so, do not obstruct other road users.
The heat generated by braking dries the brake
discs and brake pads, and protects them
against corrosion.
This way, brake power is available immedi‐
ately, whenever it is needed.
Downhill gradients
General
When driving on long or steep downhill
stretches, use the gear in which the least brak‐
ing is required. Otherwise the brake system
can overheat and braking effect is reduced.
Manual gearbox:
The braking effect can be additionally in‐
creased by shifting down, even into first gear, if
applicable.
M double clutch transmission:
The braking action of the engine can be boos‐
ted further by shifting down in Sequential
mode, see page 97.
Safety notes
WARNING
Even slight, continuous pressure on the
brake pedal can cause overheating, brake pad
wear or even brake system failure. There is a
danger of accidents. Avoid excessive loads on
the brake.◀
WARNING
When idling or with the engine switched
off, safety-relevant functions are restricted or
no longer available, for example the braking ef‐
fect of the engine or power assistance for the
braking force and steering. There is a danger
of accidents. Do not drive at idle speed or with
the engine switched off.◀
