Economical driving
Better driving economy may be obtained by thinking ahead, avoiding rapid starts and stopsand adjusting the speed of your vehicle to imme-diate traffic conditions.
Economical driving conserves natural
resources
Observe the following rules: • Bring the engine to normal operating tem- perature as soon as possible by driving witha light foot on the accelerator pedal for thefirst few minutes of operation. A cold engineuses more fuel and is subject to increasedwear.
• Whenever possible, avoid using the vehiclefor driving short distances. This does notallow the engine to reach normal operatingtemperature.
• Drive carefully and avoid rapid accelerationand hard braking.
• Use the transmission's Drive (
D) position as
often as possible and avoid using kick-down.
• Using the engine's optional Eco function canhelp improve fuel economy. For additional information, see ECO
* (p. 273).
• Using the transmission's Sport mode may increase fuel consumption somewhat. Use the transmission's Drive (
D) position as often
as possible. For additional information about Sport mode, see Transmission – Geartronic (p. 264).
• Do not exceed posted speed limits.
• Avoid carrying unnecessary items (extra load)in the vehicle.
• Maintain correct tire pressure. Check tirepressure regularly (when tires are cold).
• Remove snow tires when threat of snow orice has ended.
• Note that roof racks, ski racks, etc, increaseair resistance and also fuel consumption.
• At highway driving speeds, fuel consumptionwill be lower with the air conditioning on andthe windows closed than with the air condi-tioning off and the windows open.
• Using the onboard trip computer's fuel con-sumption modes can help you learn how todrive more economically.
Other factors that decrease gas mileage are:
• Dirty air cleaner
• Dirty engine oil and clogged oil filter
• Dragging brakes
• Incorrect front end alignment
Some of the above mentioned items and othersare checked at the standard maintenance inter-vals.

If the automatic transmission begins to over- heat, a message will be displayed in the textwindow.
• Avoid overload and other abusive operation.
• Hauling a trailer affects handling, durability,and economy.
• It is necessary to balance trailer brakes withthe towing vehicle brakes to provide a safestop (check and observe state/local regula-tions).
• Do not connect the trailer's brake systemdirectly to the vehicle's brake system.
• More frequent vehicle maintenance isrequired.
• Remove the ball holder when the hitch is notbeing used.
NOTE
•When parking the vehicle with a trailer on a hill, apply the parking brake before put- ting the gear selector in
P. Always follow
the trailer manufacturer's recommenda- tions for wheel chocking.
• When starting on a hill, put the gear selector in
D before releasing the parking
brake.
• If you use the manual (Geartronic) shift positions while towing a trailer, make surethe gear you select does not put toomuch strain on the engine (using toohigh a gear).
• The drawbar assembly/trailer hitch maybe rated for trailers heavier than the vehi-cle is designed to tow. Please adhere toVolvo's recommended trailer weights.
• Avoid driving with a trailer on inclines ofmore than 15%.
CAUTION
The maximum trailer weights listed are only applicable for altitudes up to 3,280 ft(1000 m) above sea level. With increasingaltitude the engine power and therefore thecar's climbing ability are impaired because ofthe reduced air density, so the maximumtrailer weight has to be reduced accordingly.The weight of the vehicle and trailer must bereduced by 10% for every further 3,280 ft(1,000 m) (or part thereof). When towing5,000 lbs (2,250 kg) hill inclination is restric-ted to 14%.

Trailer Stability Assist (TSA)
Trailer Stability Assist is a system designed to help stabilize a vehicle that is towing a trailerwhen the vehicle and trailer have begun to swayand is part of the stability system. For informationon the stability system, see Stability system –introduction (p. 172)
FunctionA vehicle towing a trailer may begin to sway for various reasons. Normally this only occurs at highspeeds but, for example, if the trailer is overloa-ded or if the load is unevenly distributed in thetrailer, there is risk of swaying at speeds betweenapproximately 45-55 mph (70-90 km/h). 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 surface or drive over a bump
• Sudden movements of the steering wheel
Facts about TSA
• TSA intervenes at speeds above approxi-mately 40 mph (60 km/h)
• The stability system symbol in the instrumentpanel will flash when TSA is working
• If the driver switches off the stability system'sSpin Control function, TSA will also beswitched off (but will be on again the nexttime the engine is started) •
TSA may not intervene when the vehicle andtrailer begin to sway if the driver tries to com-pensate for the swaying motion by movingthe steering wheel rapidly
How TSA worksOnce swaying has begun, it can be very difficultto stop, which makes it difficult to control thevehicle and trailer. The TSA system continuously monitors the vehi- cle's movements, particularly lateral movement. Ifthe system detects a tendency to sway, thebrakes are applied individually on the frontwheels, which has a stabilizing effect on the vehi-cle and trailer. This is often enough to enable thedriver to regain control of the vehicle. If this is not adequate to stop the swaying motion, the brakes are applied to all of the wheels on thevehicle and on the trailer if it is equipped withbrakes, and engine power is temporarily reduced.As the swaying motion begins to decrease andthe vehicle-trailer have once again become sta-ble, TSA will now stop regulating the brakes/engine power and the driver regains control ofthe vehicle.

Towing the vehicle Always check with state and local authorities before attempting to tow another vehiclebecause this type of towing is subject to regula-tions regarding maximum towing speed, lengthand type of towing device, lighting, etc.
1. With the remote key fully pressed into theignition slot 17
, press START/STOP ENGINE
for approximately 2 seconds to activate igni- tion mode II.
2. The remote key must remain in the ignition slot18
for the entire time that the vehicle is
being towed.
3. Keep the tow rope taut when the towing vehicle slows down by applying light pressure on the brake pedal. This will help prevent jar-ring movements of the vehicle being towed.
4. Be prepared to apply the brakes to stop the vehicle being towed.
CAUTION
General towing precautions:
• Please check with state and local author- ities before attempting this type of tow-ing, as vehicles being towed are subjectto regulations regarding maximum towingspeed, length and type of towing device,lighting, etc.
• If the vehicle's battery is dead, see Jumpstarting (p. 261) to provide current forreleasing the electric parking brake and to move the gear selector from the
P
position to N. If this is not possible, see
Transmission – shiftlock override (p. 267) for information about manually overridingthe shiftlock system to move the gear selector from P to N.
• Maximum speed: 50 mph (80 km/h). Do not exceed the maximum allowable tow-ing speed.
• Maximum distance with front wheels onground: 50 miles (80 km).
• The vehicle should only be towed in theforward direction.

system that illuminates a low tire pressure telltale (
) when one or more of your tires is signifi-
cantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stopand check your tires as soon as possible, andinflate them to the proper pressure. Driving on a significantly under-inflated tire cau- ses the tire to overheat and can lead to tire fail-ure. Under-inflation also reduces fuel efficiencyand tire tread life, and may affect the vehicle'shandling and stopping ability. Please note that atire pressure monitoring system is not a substi-tute for proper tire maintenance, and it is the driv-er's responsibility to maintain correct tire pres-sure, even if under-inflation has not reached thelevel to trigger illumination of the system's lowtire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when thesystem is not operating properly. The monitoringsystem's malfunction indicator is combined withthe low tire pressure telltale. When the system detects a malfunction, the tell- tale will flash for approximately one minute andthen remain continuously illuminated. Thissequence will continue upon subsequent vehiclestart-ups as long as the malfunction exists. Whenthe malfunction indicator is illuminated, the sys-tem may not be able to detect or signal low tirepressure as intended. System malfunctions may occur for a variety ofreasons, including the installation of replacementor alternate tires or wheels on the vehicle thatprevent the tire pressure monitoring system fromfunctioning properly. Always check the system's malfunction telltale after replacing one or more tires or wheels onyour vehicle to ensure that the replacement oralternate tires and wheels allow the system tocontinue to function properly.
NOTE
The system indicates low tire pressure but does not replace normal tire maintenance. Forinformation on correct tire pressure, pleaserefer to the tire inflation decal on the driver'sdoor opening or consult your Volvo retailer.
WARNING
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control of thevehicle.

Tire Monitor - introduction (p. 317)
• Tire Pressure Monitoring System (TPMS) – general information (p. 320)
Tire Monitor - introduction Tire Monitor uses the rotational speed of the tires in combination with signal analysis of theABS sensor signals to determine if they areproperly inflated.
When a tire is under-inflated, its diameter (and consequently also its rotational speed) changes.By comparing the individual tires with each otherit is possible to determine if one or more tires areunder inflated. When low inflation pressure is detected or if the system is not functioning properly, Tire Monitorwill light up the tire pressure warning light (
) (also referred to as a telltale) in the
instrument panel and will display one of several messages in the text window, for example:

Fuses – introduction
The fuses help protect the vehicle's electrical components from overloading.
There are relay/fuseboxes located in the engine compartment, the passenger compartment andthe cargo area. If an electrical component fails to function, this may be due to a blown fuse. The easiest way tosee if a fuse is blown is to remove it. To do so:
1. Pull the fuse straight out. If a fuse is difficult to remove, a special fuse removal tool is
located on the inside of the engine com- partment fusebox cover .
2. From the side, examine the curved metal wire in the fuse to see if it is intact.
If the wire is broken, insert a new fuse of thesame color and amperage (written on the fuse). If fuses burn out repeatedly, have the electrical system inspected by a trained and qualified Volvoservice technician.
WARNING
Never use metal objects or fuses with higher amperage than those stated on the followingpages. Doing so could seriously damage oroverload the vehicle's electrical system.
