• TSA may not intervene when the vehicleand trailer begin to sway if the driver triesto compensate for the swaying motion bymoving the steering wheel rapidly
How TSA worksOnce swaying has begun, it can be very diffi- cult to stop, which makes it difficult to controlthe vehicle and trailer. The TSA system continuously monitors the vehicle's movements, particularly lateralmovement. If the system detects a tendencyto sway, the brakes are applied individuallyon the front wheels, which has a stabilizingeffect on the vehicle and trailer. This is oftenenough to enable the driver to regain controlof the vehicle. If this is not adequate to stop the swaying motion, the brakes are applied to all of thewheels on the vehicle and on the trailer if it isequipped with brakes, and engine power istemporarily reduced. As the swaying motionbegins to decrease and the vehicle-trailerhave once again become stable, TSA will nowstop regulating the brakes/engine power andthe driver regains control of the vehicle.

Towing the vehicle
Always check with state and local authorities before attempting to tow another vehiclebecause this type of towing is subject to reg-ulations regarding maximum towing speed,length and type of towing device, lighting, etc.
1. With the remote key fully pressed into the
ignition slot 15
, press START/STOP
ENGINE for approximately 2 seconds to
activate ignition mode II. 2. The remote key must remain in the igni-
tion slot 16
for the entire time that the vehi-
cle is being towed.
3. Keep the tow rope taut when the towing vehicle slows down by applying light pressure on the brake pedal. This willhelp prevent jarring movements of thevehicle being towed.
4. Be prepared to apply the brakes to stop the vehicle being towed.
15Not necessary in vehicles with the optional keyless drive.

WARNING
• When the vehicle is being towed, the ignition should be in mode
II (in mode
I , all of the vehicle's airbags are deac-
tivated). For more information, seeIgnition modes (p. 73)
• Never remove the remote key from theignition slot when the vehicle is beingtowed. For vehicles with keyless drive,the remote key must remain inside thevehicle.
• The power brakes and power steeringwill not function when the engine is notrunning. Approximately 5 times morepressure will be required on the brakepedal and the steering wheel will beconsiderably harder to turn.
• The towing eyelets must not be usedfor pulling the vehicle out of a ditch orfor any similar purpose involvingsevere strain.

• Towing by tow truck (p. 271)
Towing by tow truck
When necessary, call for professional help from an authorized towing company. Volvorecommends the use of flat bed equipment.
CAUTION
In certain conditions, the towing eyelet may be used to pull the vehicle onto aflatbed tow truck.
• The vehicle's position and ground clearance determine if it can be pulledup onto a flatbed tow truck using thetowing eyelet.
• If the angle of the tow truck’s ramp istoo steep or the ground clearanceunder the vehicle is insufficient, dam-age could occur by attempting to pullthe vehicle using the towing eyelet.
• If necessary, lift the vehicle using thetow truck’s lifting device.
WARNING
No person or object should be behind the tow truck while the vehicle is being pulledup onto the flatbed.
CAUTION
• The vehicle should always be towed in the forward direction.
• Vehicles with All Wheel Drive (AWD)*that are being towed with the frontwheels off the ground should not betowed at a speed above approx.45 mph (70 km/h) and should not betowed farther than 30 miles (50 km).

Maintenance – owner maintenance
Periodic maintenance requirements and inter- vals are described in your vehicle's Warrantyand Service Records Information booklet. The following points can be carried out between the normally scheduled maintenanceservices.
Owner maintenance
Each time the car is refueled:
•Check the engine oil level.
• Clean the windshield, windshield wipers, headlights, and taillights.
Monthly:
• Check cold tire pressure in all tires. Inspect the tires for wear.
• Check that engine coolant and other fluidlevels are between the indicated "min"and "max" markings.
• Clean interior glass surfaces with a glasscleaner and soft paper towels.
• Wipe driver information displays with asoft cloth.
• Visually inspect battery terminals for cor-rosion. Corrosion may indicate a looseterminal connector, or a battery near theend of its useful service life. Consult yourVolvo retailer for additional information.
As needed:Wash the car, including the undercarriage, to reduce wear that can be caused by a buildup of dirt, and corrosion that can be caused bysalt residues. Clean leaves and twigs from air intake vents at the base of the windshield, and from otherplaces where they may collect.

The appearance of the engine compartment may vary depending on engine model.
WARNING
The cooling fan (located at the front of the engine compartment, behind the radiator)may start or continue to operate (for up to6 minutes) after the engine has beenswitched off.
WARNING
Before performing any operations in the engine compartment, the ignition shouldalways be completely switched off (inmode 0, see Ignition modes (p. 73)) and
there should be no remote keys in the pas-senger compartment. The gear selectorshould be in the P (park) position. If the
engine has been running, wait until it hascooled before touching any components inthe engine compartment. The distributor ignition system operates at very high voltages. Special safety precau-tions must be followed to prevent injury.Always turn the ignition off when:
• Replacing distributor ignition compo- nents e.g. plugs, coil, etc.
• Do not touch any part of the distributorignition system while the engine is run-ning. This may result in unintendedmovements and body injury.

Checking the levelThe fluid reservoir is concealed under the round cover at the rear of the engine com-partment. The round cover must be removedfirst before the reservoir cap can beaccessed. Check, without removing the cap, that there is sufficient fluid in the reservoir. Fluid type: DOT 4 boiling point >536 °F
(>280 °C).Replace : The fluid should be replaced
according to the intervals specified in the Warranty and Service Records Informationbooklet. When driving under extremely hard condi- tions (mountain driving, etc), it may be neces-sary to replace the fluid more often. Consult atrained and qualified Volvo service technician. Always entrust brake fluid changing to a trained and qualified Volvo service technician.
WARNING
• If the fluid level is below the
MIN mark
in the reservoir or if a brake-related message is shown in the informationdisplay: DO NOT DRIVE . Have the car
towed to a trained and qualified Volvoservice technician and have the brakesystem inspected.
• Dot 4 should never be mixed with anyother type of brake fluid.
Filling1. Turn and open the cover.
2. Unscrew the reservoir cap and fill the
fluid. The level must be between the MIN
and MAX marks.
Engine compartment – power steering fluid
The fluid level must be between the MIN and
MAX marks. For capacities and recom-
mended fluid grade, see Fuel tank volume – specification and volume (p. 362).
Check the level frequently. It does not nor- mally require changing.
WARNING
If a problem should occur in the power steering system or if the vehicle has noelectrical current and must be towed, it isstill possible to steer the vehicle. However,keep in mind that greater effort will berequired to turn the steering wheel.
