Trailer Stability Assist
*
Trailer Stability Assist (TSA 11
) 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 12
.
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.

WHEELS AND TIRES
538
WARNING
The vehicle must never be driven with more than one "Temporary Spare" tiremounted.
Driving with a spare wheel may alterthe driving characteristics of the vehi-cle. Replace the spare wheel with anormal wheel as soon as possible.
The spare wheel is smaller than thenormal wheel, which affects the vehi-cle's ground clearance. Watch for highcurbs and do not wash the vehicle inan automatic car wash when a sparewheel is mounted.
Follow the manufacturer's recom-mended tire inflation pressure for thespare wheel.
On all-wheel drive vehicles, the driveon the rear axle can be disconnected.
If the spare wheel is mounted on thefront axle, snow chains must not beused.
The spare wheel must not be repaired.
CAUTION
The vehicle must not be driven with wheels of different dimensions or with a spare tireother than the one that came with the vehi-cle. The use of different size wheels canseriously damage your vehicle's transmis-sion.

When changing wheels (p. 532)
Recommended tire pressure (p. 527)
Handling spare tires Follow these instructions regarding handling the spare wheel.
This illustration is generic and appearance may vary.
The spare wheel is stored in a bag and should be secured with two straps onto the floor ofthe trunk/cargo compartment when the vehi-cle is being driven. The straps should be strap-ped down crosswise over the wheel, attachedto the load anchoring eyelets and pulled taut. Wheel changing tools are located under the cargo compartment floor.
Polestar EngineeredIf your vehicle is Polestar Engineered,Temporary Spare tires will not fit on the frontwheel axle due to the larger brakes. Tires should only be moved between the front and back, never from right to left or vice versa.

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 7.5x18ET 45 235/45. Volvo does not recommenduse of snow chains on for Polestar Engi-neered, but AutoSock can be used as a sup-plement to winter tires for the wheel dimen-sion 8x19 ET 42 235/40.
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 withoutsnow as this wears out both the snowchains and the tires.
The handling of the vehicle can be adversely 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

Automatic car washes
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.
Washing your vehicle in an automatic car wash is a fast and easy way to keep your vehi-cle clean, but it does not reach all areas of thevehicle. Volvo recommends washing yourvehicle by hand or supplementing automaticcar washes with a hand wash.
NOTE
Volvo recommends not washing the vehi- cle in an automatic car wash during thefirst few months; the paintwork on newvehicles takes some time to fully harden.
CAUTION
Before driving the vehicle into a car wash, deactivate the Automatic Braking whenStationary and Automatic Parking BrakeApplication functions. If the functions arenot deactivated, the brake system willseize when the vehicle is stationary and thevehicle will not be able to roll.
CAUTION
For automatic car washes in which the vehicle is pulled forward on rolling wheels:
1. Before washing the vehicle, make sure that the automatic rain sensor is deac- tivated. If it is not deactivated andinadvertently starts, the wiper armscould be damaged.
2. To help prevent damage from the auto- matic car wash machinery, make surethat the door mirrors are folded in,antennas retracted or removed, andany auxiliary lights secured.
3. Drive into the automatic car wash.
4. Turn off the "Automatic Braking when Stationary" function using the
but-
ton in the tunnel console.
5. Turn off the "Automatic Parking Brake Application" function in the center dis- play's Top view.
6. Turn off the engine by turning the start knob in the tunnel console clockwise.Hold the knob in position for at least2 seconds.
The vehicle is now ready for the automaticcar wash.
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.

The maximum trailer weights listed are only applicable for altitudes up to3280 ft (1,000 m) above sea level.With increasing altitude the enginepower and therefore the car's climbingability are impaired because of thereduced air density, so the maximumtrailer weight has to be reducedaccordingly. The weight of the car andtrailer must be reduced by 10% forevery further 3280 ft (1,000 m) (orpart thereof).
