Economical driving
Drive economically and environmentally con- scious by thinking ahead, avoiding rapid startsand stops and adapting driving style and speedto the current traffic conditions.
Driving economically conserves natural resources
Observe the following rules:
• Do not warm up the engine by idling. It is better to begin driving normally immediately after starting the engine. A cold engine uses more fuel than a warm engine and is subject to increased wear.
• Whenever possible, avoid using the vehicle todrive short distances. The engine does nothave time to reach a normal operating tem-perature and this leads to increased fuelconsumption.
• Maintain a steady speed and a generous fol-lowing distance to traffic ahead to minimizebraking.
• For lower fuel consumption, activate Ecodrive mode.
• Use the Eco Coast function in drive mode Eco - engine braking is deactivated, allowing the vehicle's kinetic energy to be used to rollgreater distances.
• Use gear
D as often as possible and avoid
using the kick-down function. •
Fuel consumption is increased at highspeeds - air resistance increases with speed.
• Remove unnecessary items from the vehicle- the heavier the load, the higher the fuelconsumption.
• Maintain the correct pressure in the tires andcheck pressure regularly.
• The type of tires used could affect fuel con-sumption - consult a retailer for advice onsuitable tires.
• Do not use winter tires after the winter sea-son has ended.
• Roof loads increase air resistance andincrease fuel consumption. Remove roofboxes, ski racks, etc. that are not in use.
• Avoid driving with the windows open.
• Using the trip computer's fuel consumptionindicators can help you learn how to drivemore economically.
Other factors that decrease fuel
consumption
• Dirty air cleaner.
• Dirty engine oil and clogged oil filter.
• Incorrect front-end alignment.
• Incorrect wheel alignment.
Some of the above items and others are checked as part of Volvo's standard maintenance sched-ule.

Emission controls
Three-way catalytic converter
•Keep your engine properly tuned. Certain engine malfunctions, particularly involving theelectrical, fuel or distributor ignition systems,may cause unusually high three-way catalyticconverter temperatures. Do not continue tooperate your vehicle if you detect enginemisfire, noticeable loss of power or otherunusual operating conditions, such as engineoverheating or backfiring. A properly tunedengine will help avoid malfunctions thatcould damage the three-way catalytic con-verter.
• Do not park your vehicle over combustiblematerials, such as grass or leaves, which cancome into contact with the hot exhaust sys-tem and cause such materials to ignite undercertain wind and weather conditions.
• Excessive starter cranking (in excess of oneminute), or an intermittently firing or floodedengine can cause three-way catalytic con-verter or exhaust system overheating.
• Remember that tampering or unauthorizedmodifications to the engine, the Engine Con-trol Module, or the vehicle may be illegal andcan cause three-way catalytic converter orexhaust system overheating. This includes:altering fuel injection settings or compo-nents, altering emission system components or location or removing components, and/orrepeated use of leaded fuel.NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxygen content of the exhaust gases. Readings are fedinto a control module that continuously monitorsengine functions and controls fuel injection. Theratio of fuel to air into the engine is continuouslyadjusted for efficient combustion to help reduceharmful emissions.

Battery drain The electrical functions in the vehicle drain the battery to varying degrees. Avoid using ignitionmode II when the engine is switched off. Use
ignition mode I instead, as this uses less electri-
cal current.
Note that certain accessories may also drain power from the electrical system. Do not usefunctions that use a lot of electrical current whenthe engine is turned off. Examples of such func-tions are:
• blower
• headlights
• windshield wipers
• audio system (especially at high volume).
If the starter battery voltage is low, a message isshown in the driver display. The vehicle's energy-saving function will then turn off or reduce certainfunctions, such as the blower and/or the audio system.
–Charge the battery by starting the engine and let it run for at least 15 minutes (drivingcharges the battery faster than letting theengine idle).

Trailer Stability Assist *
Trailer Stability Assist (TSA 10
) is a function
designed to help stabilize a vehicle that is tow- ing a trailer when the vehicle and trailer havebegun to sway. The function is part of the Elec- tronic Stability Control system ESC 11
.
Reasons for swayingA vehicle towing a trailer may begin to sway for various reasons. Normally this only occurs at highspeeds. However, if the trailer is overloaded orunevenly distributed, e.g. too far back, there is arisk 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 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 vehicle andtrailer difficult to control and there is a risk ofswerving into oncoming traffic or driving off theroad.
Trailer Stability Assist functionTrailer Stability Assist continuously monitors thevehicle's movements, particularly lateral move- ments. If swaying is detected, the brakes areapplied individually on the front wheels, which hasa stabilizing effect on the vehicle and trailer. Thisis often enough to enable the driver to regaincontrol 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 wheels andengine power is temporarily reduced. As theswaying motion begins to decrease and the vehi-cle and trailer have once again become stable,TSA stops regulating the brakes/engine powerand the driver regains control of the vehicle.
NOTE
Trailer Stability Assist is deactivated if the driver selects the sport mode by deactivating
ESC in the center display's menu system.
Trailer Stability Assist may not intervene if the driver tries to compensate for the swaying motionby moving the steering wheel rapidly, becausethe system will then not be able to determine if itis the trailer or the driver causing the swaying.
When Trailer Stability Assist is activated, the
ESC symbol is
displayed in the instrument panel.

stop. Fasten the eyelet securing by, for exam- ple, inserting a lug wrench * through it and
using this as a lever.
CAUTION
It is important that the towing eye is screwed in securely as far as possible.
Removing the towing eyelet:
–After use, unscrew the towing eyelet and return it to its storage location. Replace the cover on the bumper.
In certain conditions, the towing eyelet may be used to pull the vehicle onto a flatbed tow truck.The vehicle's position and ground clearancedetermines if this is possible. If the incline of the tow truck is too steep or if the ground clearance under the vehicle is insufficient, attempting to pull it up using the towing eyeletmay result in damage. If necessary, lift the vehicle using the tow truck's lifting device instead of using the towing eyelet.
WARNING
No person or object should be behind the tow truck when the vehicle is lifted onto the bedof the truck.
CAUTION
The towing eyelet is only intended for towing on roads, and must
not be used to pull vehi-
cles from ditches or any similar purpose involving severe strain. Call a tow truck forprofessional assistance.
