Trailer Stability Assist *
Trailer Stability Assist (TSA 18
) is part of the
ESC 19
stability system and 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 addedwhen installing a towbar. Contact a Volvoretailer for more information.
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 lateralmovements. 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 activates ESC Sport Mode in the
center display's menu system.
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.
NOTE
A vehicle software update is required when a towbar is retrofitted. Contact a Volvoretailer.

Towing using a towline
This section refers to one vehicle being towed behind another using a towline.
Before towing another vehicle, check applica- ble speed limit regulations.
Preparations and towing
CAUTION
For some transmission variants, it is not possible to shift from P position if theengine is switched off. Contact an author-ized Volvo workshop for assistance towingor call a professional towing service.
CAUTION
Note that the vehicle must always be towed with the wheels rolling forward.
Do not tow a vehicle with automatictransmission at a speed greater than80 km/h (50 mph) or for a distancegreater than 80 km (50 miles).
WARNING
Ignition mode
II must be active – all
airbags are deactivated in ignition mode I.
Always have the remote key in thevehicle when it is towed.
WARNING
The brake and steering servos do not work when the engine is off – it takesabout 5 times more pressure on the brakepedal and steering requires much moreeffort than normal.
1. Turn on the hazard warning flashers.
2. Attach the towline to the towing eyelet.
3. Put the vehicle in ignition mode II – with-
out pressing the brake pedal, turn the start knob clockwise and hold it there for about4 seconds. Release the knob, which willautomatically return to its original position.
4. Move the gear selector to neutral (N) and release the parking brake. If the battery charge level is too low, it may not be possible to release the parkingbrake. Connect an auxiliary battery to thevehicle if the battery is discharged.
> The towing vehicle can now start driv-ing. 5. Keep the towline taut when the towing
vehicle slows down by applying light pres- sure to the brake pedal. This will helpavoid jarring movements.
6. Be prepared to apply the brakes to stop the vehicle.
Jump startingDo not tow the vehicle to start the engine. Usean auxiliary battery if the start battery's chargelevel is so low that the engine cannot bestarted.
CAUTION
Attempting to tow with the engine running could result in damage to the three-waycatalytic converter.

WHEELS AND TIRES
541
Snow chainsUsing snow chains and/or snow tires can help improve traction in winter driving condi-tions.
Volvo does not recommend use of snow chains on wheel dimensions other than these 16
:
7x16 ET 37 215/60
7x17 ET 40.5 225/50
8x18 ET 42 235/45
WARNING
Use Volvo genuine snow chains or equiva- lent snow chains that are suitable for thevehicle model and the tire and wheel sizes.Only
one-sided snow chains are permit-
ted. If uncertain about snow chains, Volvo rec- ommends contacting an authorized Volvoworkshop. Use of the wrong snow chainscould cause serious damage to the vehicleand result in an accident.
CAUTION
Snow chains can be used on the vehicle, with the following restrictions:
Always follow the manufacturer'sinstallation instructions carefully. Installchains as tightly as possible andretighten periodically.
Only put snow chains on the frontwheels (also applies to all-wheel drivevehicles).
If accessory, aftermarket or "custom"tires and wheels with different dimen-sions than the original tires and wheelsare used, snow chains in some casesmay NOT be used. Sufficient distancebetween the chains and brakes, sus-pension and body components mustbe maintained.
Check local regulations regarding theuse of snow chains before installing.
Never exceed the snow chain manu-facturer's specified maximum speedlimit. Under no circumstances shouldyou exceed 50 km/h (30 mph).
Avoid bumps, holes or sharp turnswhen driving with snow chains.
Avoid driving on surfaces without snow as this wears out both the snowchains and the tires.
The handling of the vehicle can beadversely affected when driving withchains. Avoid fast or sharp turns aswell as locked wheel braking.
Some types of strap-on chains affectbrake components and therefore mustNOT be used.
Consult a Volvo retailer for more information about snow chains.

MAINTENANCE AND SERVICE
* Option/accessory.617
CAUTION
The system will automatically change to P
mode if the above steps are not followed. In P mode, the wheels are locked, which
they should not be when the vehicle isbeing washed in a car wash.
NOTE
Keep in mind that if the vehicle is equipped with the keyless locking and unlocking function *, the doors and tailgate/trunk lid
may open when washing the vehicle if the remote key is within range.
Testing the brakes
WARNING
Always test the brakes after washing the vehicle, including the parking brake, toensure moisture and corrosion do notattach the brake pads and impair brakefunctionality.
Lightly depress the brake pedal from time to time when driving long distances in rain orslush. The heat from the friction will helpwarm up and dry the brake pads. Do the sameafter starting the vehicle in very damp or coldweather.

High-pressure washing The vehicle should be washed as soon as it becomes dirty. The longer the dirt remains,the more difficult it will be to keep the vehicleclean. It could also lead to paint damage.Wash the vehicle in a car wash or garagewith an oil separator. Use a car washingdetergent recommended by Volvo.
If washing the vehicle with a high-pressure wash, use sweeping movements and keep thenozzle at least 30 cm (13 in.) from the vehicle.Do not spray directly onto locks.
