Extreme weather conditions, towing a trailer, high altitude and lower fuel gradethan recommended are factors that cansignificantly increase the vehicle's fuel con-sumption.
Trailer weights
WARNING
Please adhere to the recommendations provided for trailer weight. If the recom-mendations are not followed, the vehicleand trailer may be difficult to control duringevasive maneuvers and braking.
NOTE
The specified maximum trailer weights are those permitted by Volvo. National vehicleregulations may set additional restrictionson trailer weight and speed. The trailerhitches may be certified for higher towingweights than the vehicle is permitted totow.
Self-leveling suspension *The vehicle's self-leveling system attempts to keep the vehicle at a constant level, regardlessof load (up to the maximum permitted weight).When the vehicle is stationary, the rear end of the vehicle will be slightly lowered, which isnormal.
Driving in hilly terrain or hot weatherIn 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 enginespeed.
Steep inclines
Do not lock the automatic transmission into a higher gear than what the engine can handle
‒
it is not always preferable to drive in highgears at low rpm.

Trailer Stability Assist *
Trailer Stability Assist (TSA 16
) is a function
designed to help stabilize a vehicle that is towing a trailer when the vehicle and trailerhave begun to sway. The function is part of the Electronic Stability Control system ESC 17
.
Reasons for swayingA vehicle towing a trailer may begin to sway for various reasons. Normally this only occursat high speeds. However, if the trailer is over-loaded or unevenly distributed, e.g. too farback, there is a risk of swaying even at lowspeeds. 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 anuneven road or over a bump.
Sudden movements of the steering wheel.
Once swaying has begun, it can be difficult orimpossible to stop it. This makes the vehicleand trailer difficult to control and there is a riskof swerving into oncoming traffic or driving offthe road.
Trailer Stability Assist functionTrailer Stability Assist continuously monitorsthe vehicle's movements, particularly lateral movements. If swaying is detected, the brakesare applied individually on the front wheels,which has a stabilizing effect on the vehicleand trailer. This is often enough to enable thedriver to regain control of the vehicle. If the Trailer Stability Assist function's first attempt is not adequate to stop the swayingmotion, the brakes are applied on all wheelsand engine power is temporarily reduced. Asthe swaying motion begins to decrease andthe vehicle and trailer have once againbecome stable, TSA stops regulating thebrakes/engine power and the driver regainscontrol of the vehicle.
NOTE
Trailer Stability Assist is deactivated if the driver selects the sport mode by deactivat- ing
ESC in the center display's menu sys-
tem.
Trailer Stability Assist may not intervene if the driver tries to compensate for the swayingmotion by moving the steering wheel rapidly,because the system will then not be able todetermine if it is the trailer or the driver caus-ing the swaying. When Trailer Stability Assistis activated, the ESC symbolis displayed in the instrumentpanel.

Towing using a towline
This section refers to one vehicle being towed behind another using a towline.
Never attempt to tow a Twin Engine vehicle behind another vehicle as this could damagethe electric motor. The vehicle must instead belifted onto a tow truck and transported with allfour wheels on the bed or lifting platform ofthe truck (no wheels may touch the road).
Towing another vehicleTowing another vehicle requires a lot of power - use the Constant AWD drive mode. This
helps charge the hybrid battery and improve the vehicle's driving and roadholding characte-ristics. Before towing another vehicle, check applica- ble speed limit regulations.
Jump startingNever attempt to tow the vehicle to start theengine, as this could damage the electricmotor. Use an auxiliary battery if the start bat-tery's charge level is so low that the enginecannot be started.
CAUTION
Attempts to tow-start the vehicle could cause damage to the electrical drive motorand three-way catalytic converter.
