the vehicle will be slightly lowered, which is
normal.
Driving in hilly terrain or hot weather
In certain conditions, there is a risk of over-
heating when driving with a trailer. If overheat-
ing of the engine and drive system is detected,
a warning symbol will illuminate in the instru-
ment panel and a message will appear.
The automatic transmission selects the opti-
mal gear for the current load and engine
speed.

Do not lock the automatic transmission into a
higher gear than what the engine can handle ‒
it is not always preferable to drive in high
gears at low rpm.

Trailer Stability Assist*
Trailer Stability Assist (TSA 18 ) is a function
designed to help stabilize a vehicle that is
towing a trailer when the vehicle and trailer
have begun to sway. The function is part of
the Electronic Stability Control system ESC
Reasons for swaying
A vehicle towing a trailer may begin to sway
for various reasons. Normally this only occurs
at high speeds. However, if the trailer is over-
loaded or unevenly distributed, e.g. too far
back, there is a risk of swaying even at low
speeds.
Swaying may be caused by factors such as:
The vehicle and trailer are hit by a sudden,
•
strong crosswind.
The vehicle and trailer are traveling on an
•
uneven road or over a bump.
Sudden movements of the steering wheel.
•
Once swaying has begun, it can be difficult or
impossible to stop it. This makes the vehicle
and trailer difficult to control and there is a risk
of swerving into oncoming traffic or driving off
the road.
Trailer Stability Assist function
Trailer Stability Assist continuously monitors
the vehicle's movements, particularly lateral
movements. If swaying is detected, the brakes
are applied individually on the front wheels,
