Conserving electrical current
Keep the following in mind to help minimize bat- tery drain:
• When the engine is not running, avoid using ignition mode
II. Many electrical systems (the
audio system, the optional navigation system, power windows, etc) will function in ignition modes 0 and I. These modes reduce drain
on the battery.
• Please keep in mind that using systems, accessories, etc., that consume a great dealof current when the engine is not runningcould result in the battery being completelydrained. Driving or having the engine runningfor approximately 15 minutes will help keepthe battery charged.
• The optional 12-volt socket in the cargoarea (p. 143) area provides electrical currenteven with the ignition switched off, whichdrains the battery.
Before a long distance trip
It is always worthwhile to have your vehicle checked by a trained and qualified Volvo servicetechnician before driving long distances. Yourretailer will also be able to supply you with bulbs,fuses, spark plugs and wiper blades for your usein the event that problems occur.
As a minimum, the following items should be checked before any long trip:
• Check that engine runs smoothly and thatfuel consumption is normal.
• Check for fuel, oil, and fluid leakage.
• Have the transmission oil level checked.
• Check condition of drive belts.
• Check state of the battery's charge.
• Examine tires carefully (the spare tire aswell), and replace those that areworn (p. 302). Check tire pressure (p. 309).
• The brakes, front wheel alignment, and steer-ing gear should be checked by a trained andqualified Volvo service technician only.
• Check all lights, including high beams.
• Reflective warning triangles are legallyrequired in some states/provinces.
• Have a word with a trained and qualifiedVolvo service technician if you intend to drivein countries where it may be difficult toobtain the correct fuel. •
Consider your destination. If you will be driv-ing through an area where snow or ice arelikely to occur, consider snow tires (p. 316).

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.

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.

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:
Tire
pressure low Check tires. Adjust the inflation
pressure and recalibrate if necessary.
NOTE
If a malfunction occurs in the system, the tire pressure warning light will flash for approxi-mately 1 minute and then remain illuminated.

NOTE
To help avoid incorrect tire inflation pressure, only inflate the tires when they are cold. Thetires are considered to be cold when theyhave the same temperature as the surround-ing (ambient) air. This temperature is normallyreached after the vehicle has been parked forat least 3 hours. After driving a distance ofapproximately 1 mile (1.6 km), the tires areconsidered to be hot.
CAUTION
•After inflating the tires, always reinstall the valve cap to help avoid damage to thevalve from dirt, gravel, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
WARNING
•
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control ofthe vehicle.
• Tire monitoring systems cannot indicatesudden tire damage caused by externalfactors (e.g., a blowout) in advance.
Related information
•Tire inflation – checking pressure (p. 309)
Tire Pressure Monitoring System (TPMS) – general information TPMS uses sensors mounted in the tire valves to check inflation pressure levels. When thevehicle is moving at a speed of approximately20 mph (30 km/h) or faster, these sensorstransmit inflation pressure data to a receiverlocated in the vehicle.
NOTE
USA – FCC ID: KR5S180052050 This device complies with part 15 of the FCC rules. Operation is subject to the followingconditions: (1) This device may not causeharmful interference, and (2) this device mustaccept any interference received, includinginterference that may cause undesired opera-tion.
When low inflation pressure is detected or if a sensor is not functioning properly, TPMS will light up the tire pressure warning light (
) (also
referred to as a telltale) in the instrument panel and will display one of the following messages:
Tire pressure low, Tire needs air now or Tire

Tire Pressure Monitoring System (TPMS) – messages
Erasing warning messagesWhen a low tire pressure warning message has been displayed and the tire pressure warning light in the instrument panell (
) has come
on:
1. Use a tire pressure gauge to check the infla- tion pressure of all four tires.
2. Re-inflate the tire(s) to the correct pressure (consult the tire pressure decal on the driv- er's door opening).
3. In certain cases, it may be necessary to drive the vehicle for several minutes at a speed of20 mph (30 km/h) or faster. This will erasethe warning text and the telltale will go out.
NOTE
• The tire monitoring systems use a tem- perature compensated pressure value.This pressure value is dependent on tiretemperature and ambient temperature,which can differ from the recommendedcold tire pressure in the tire inflation tableand on the tire pressure placard locatedon the driver's side B-pillar (the structuralmember at the side of the vehicle, at therear of the driver's door opening). Thismeans that it may sometimes be neces-sary to inflate them slightly above therecommended cold pressure value(approx. 3-4 psi or 0.2-0.3 bar) in orderto reset a low tire pressure warning.
• To help avoid incorrect tire inflation pres-sure, if possible only inflate the tireswhen they are cold. The tires are consid-ered to be cold when they have the sametemperature as the surrounding (ambi-ent) air. This temperature is normallyreached after the vehicle has beenparked for at least 3 hours. After driving adistance of approximately 1 mile (1.6 km),the tires are considered to be hot.
CAUTION
•
After inflating the tires, always reinstall the valve cap to help avoid damage to thevalve from dirt, gravel, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
