Tire Pressure Monitor
Uphill gradients
After correcting the tire inflation pressure and
hitching or unhitching a trailer, reinitialize the
Tire Pressure Monitor, refer to page 92.
In the interest of safety and to avoid hindering
the smooth flow of traffic, the towing of trailers
is permissible on uphill gradients up to 12 %.
If higher trailer loads are approved at a later point
in time, the gradient limit is 8 %.
Exterior mirrors
Legislation requires two exterior mirrors that al‐
low the driver to see both rear corners of the
trailer. These types of mirrors are available as a
special accessory at your service center.
Hills
A car-trailer combination has the tendency to
swing more readily on hills.
Shift back to the next lowest gear before driving
on a hill and drive downhill slowly.
Power consumption
The consumption of the trailer tail lamps must
not exceed the following values:
High loads and external temperatures
▷
▷
▷
▷
▷
Turn signals: 42 watts per side.
Tail lamps: 60 watts per side.
Brake lamps: 84 watts in total.
Rear fog lamps: 42 watts in total.
Backup lamp: 42 watts in total.
Long trips with high loads and high exter‐
nal temperatures
On long trips with heavy trailer loads and high
external temperatures, ensure that the fuel tank
is more than 1/4 full; otherwise, engine perform‐
ance may be reduced or engine damage may
occur.◀
Keep the switch-on times of the electronic sys‐
tems/power consumers short when towing a
camper to save the vehicle battery power.
Trailer stabilization control*
The concept
Function of tail lamps
Before starting to drive, check that the tail
lamps are functioning properly; otherwise, there
is a risk of endangering other road users.◀
This system supports the driver in stopping the
swinging of a trailer.
It detects swinging and automatically brakes the
vehicle quickly to leave the critical speed range
and stabilize the car-trailer combination.
Towing a trailer
Speed with a trailer
If the trailer power socket is in use but a trailer
has not been hitched, the system can become
active in certain driving situations, such as when
using a bicycle rack with lighting.
Do not exceed a speed of 50 mph/80 km/
h; otherwise, depending on its type and weight,
the trailer may begin swinging back and forth.◀
Stopping the swinging of a trailer
Functional requirement
If the trailer begins swinging, the car-trailer com‐
bination can only be stabilized by immediately
applying the brakes hard.
The system is functional at speeds beginning at
approx. 40 mph/65 km/h while a trailer is being
towed and the trailer power socket is in use.
It is important that you make any corrective
steering maneuvers as carefully as possible and
with consideration for other road users.
System limits
▷
The system cannot intervene if the trailer
jackknifes suddenly, e.g., on slippery roads
or loose surfaces.
