Trailer Towing - BMW X7 Owner's Manual

Trailer towing

Vehicle features and
options
This chapter describes all standard, country-spe‐
cific and optional features offered with the series.
It also describes features and functions that are
not necessarily available in your vehicle, e.g., due
to the selected options or country versions. This
also applies to safety-related functions and sys‐
tems. When using these functions and systems,
the applicable laws and regulations must be ob‐
served.
General information
The permissible trailer loads, axle weights, draw‐
bar node weights, and the permissible gross ve‐
hicle weight are specified in the technical data.
The vehicle is equipped with an enhanced sus‐
pension system on the rear axle and, depending
on the vehicle type, with a more powerful cooling
system.
When the trailer power socket is in use, the vehi‐
cle will be raised or lowered to the normal level
automatically. The adjustment to the normal level
can occur when the trailer power socket is plug‐
ged in or when driving off.
Before driving
Drawbar nose weight
The maximum load of the towing vehicle is low‐
ered by the weight of the trailer hitch and the
drawbar nose weight. The drawbar nose weight
increases the vehicle weight. Do not exceed the
approved gross vehicle weight of the towing ve‐
hicle.

Trailer towing
Loading
Distribute cargo as evenly as possible on the
cargo area.
Stow the load as low and close to the trailer axle
as possible. A low center of gravity in the trailer
increases the driving safety of the entire vehicle-
trailer combination.
Do not exceed the approved gross vehicle
weight of the trailer and the permissible trailer
load of the vehicle. The smaller value applies in
each case.
Tire pressure
Note the tire inflation pressure of the vehicle and
trailer.
For the vehicle, the tire inflation pressure for
higher loads applies.
For the trailer, the specifications of the manufac‐
turer apply.

After correcting the tire inflation pressure or
hitching/unhitching a trailer, initialize the Flat Tire
