BMW X1 Owner's Handbook Manual page 185

On the vehicle, the tyre inflation pressure, see
page 200, for higher loads applies.
For the trailer, the regulations of the manufac‐
turer apply.
Runflat indicator
Reinitialise the runflat indicator after a trailer
has been attached or detached or the inflation
pressure has been corrected.
Tyre Pressure Monitor
Reinitialise the Tyre Pressure Monitor after a
trailer has been attached or detached or the in‐
flation pressure has been corrected.
Exterior mirrors
Two exterior mirrors which bring both rear cor‐
ners of the trailer into your field of view are re‐
quired by law. Such mirrors are available as
special equipment at a Service Partner or a
qualified specialist workshop.
Power consumption
Before beginning your journey, check the func‐
tion of the rear lights of the trailer or rear lug‐
gage rack.
Power of trailer rear lights or rear luggage rack
lights must not exceed following values:
▷ Turn indicators: 42 Watts per side.
▷ Tail lights: 50 Watts per side.
▷ Brake lights: 84 Watts total.
▷ Rear fog lights: 42 Watts total.
▷ Reversing lights: 42 Watts total.
Keep the switch-on times of the current con‐
sumer units in the caravan mode short in order
not to place an excessive load on the vehicle
battery.

Towing a trailer
Information
WARNING
Speeds in excess of approximately
80 km/h, approximately 50 mph can be enough
to produce a swaying or fishtailing motion, de‐
pending on the design of trailers and the loads
they are carrying. Danger of accident or dam‐
age to property.
Keep to an appropriate speed when towing a
trailer. In case of swaying or fishtailing motions,
brake immediately and make the necessary
steering corrections as carefully as possible.◀
WARNING
The tyre inflation pressure must be adap‐
ted because of the increased axle load when
towing a trailer. Driving with an inadequate tyre
inflation pressure can damage the tyres. Dan‐
ger of accident or damage to property. Do not
exceed a speed of 100 km/h/60 mph. Increase
the tyre inflation pressure of the towing vehicle
by 0.2 bar. Note the maximum possible tyre in‐
flation pressure stated on the tyre.◀
Uphill gradients
In the interest of safety and to avoid holding up
other traffic, do not attempt to climb gradients
steeper than 12 % when towing a trailer.
If higher trailer loads are permitted later, the
limit is 8 %.
Driving off on upward inclines
With Steptronic transmission: The parking
brake is automatically released when the ac‐
celerator pedal is pressed.
To prevent the vehicle from rolling back when
driving off, use the parking brake.
1. Shortly before driving off, pull and
hold the switch.
