Tyre Pressures; Downhill Gradients; Outside Mirrors; Climatic Comfort - BMW M5 Owner's Handbook Manual

Tyre pressures

Check the car's and the trailer's tyre pressures
most carefully. For the car, the inflation pres-
sures for heavy loads apply, see page 164. After
each correction of the tyre pressures, reinitial-
ise the Run Flat Indicator, see page 71.
Comply with the manufacturer's specifications
for the trailer.
Run Flat Indicator
Reinitialise the Run Flat Indicator after a trailer
has been attached or detached, see page 71.

Outside mirrors

Two outside mirrors which bring both rear cor-
ners of the trailer into your field of view are
required by law. Mirrors of this kind can be
obtained from BMW Service.
Electrical consumers
When towing a caravan, try to avoid operating
electrical equipment for too long at a time, in
order to limit the drain on the car's battery.
Before starting a journey, check that the
trailer's rear lights are operating correctly.
It is an offence to drive without functioning rear
lights, which would moreover put other road
users at risk.<
Towing a trailer
Observe the speed limit in the country in
which you are driving, but do not exceed
80 km/h (50 mph) when towing a trailer, other-
wise the outfit may become
Counteracting snaking
If the trailer nevertheless begins to snake, the
outfit can only be stabilised by braking hard
immediately. Only attempt to steer out of the
situation if this is absolutely essential, and make
any steering movements as cautiously as pos-
sible and without endangering other road users.

Gradients
In the interests of safety and to avoid holding up
other traffic, do not attempt to climb gradients
steeper than 12Ξ. If a supplementary permit
for heavier towing loads has been obtained, the
limit is 8 Ξ, see page 192.

Downhill gradients

Special care must be taken when descending
gradients, where a trailer is more susceptible to
snaking.
Before starting to descend, always change
down to the next lower gear, if necessary as far
as first gear, and drive down the hill slowly.
