When driving in hilly terrain and hot
climates
Under certain circumstances, there may be a
risk of overheating when towing a trailer. If the
engine and drive system overheats, a warning
symbol comes on in the driver display and a
message is displayed.
The automatic gearbox adapts the gears
depending on load and engine speed.
Steep inclines
Do not lock the automatic gearbox in a higher
gear than the engine "can cope with" - it is not
always a good idea to drive at a high gear with
low engine speed.
Parking on a hill

The function of trailer stability assist (TSA

),
which is included in the stability system
ESC

, is to stabilise cars towing trailers in
situations where they begin snaking. The
function is available with towbar installation,
contact a Volvo dealer for more information.
Reasons for snaking
The snaking phenomenon can occur with any
car/trailer combination. Snaking normally
occurs at high speeds. However, there is a risk
of it occurring at lower speeds if the trailer is
overloaded or the load is improperly distrib-
uted, e.g. too far back.
In order for snaking to occur, there must be a
triggering factor, e.g.:
•
Car with trailer subjected to a sudden and
powerful side wind.
•
Car with trailer drives on an uneven road
surface or in a pothole.
•
Sweeping steering wheel movements.
If snaking has started, it could be difficult or
even impossible to suppress. This makes the
car/trailer combination difficult to control and
there is a risk that you could, for example, end
up in the wrong lane or leave the carriageway.
