Function and use
Start/Stop symbol in the instrument panel
Start/Stop button on the center console
Start/Stop is activated automatically each time the engine is started 9
. The symbol in the instru-
ment panel will be displayed for several seconds when the engine starts and the indicator light inthe On/Off button will remain illuminated whilethe function is activated. All of the vehicle's systems will function while the engine is auto-stopped, although the function ofcertain systems may reduced at this time. Forexample, blower speed and high infotainmentsystem volume may be reduced to help conservethe battery's capacity.
Auto-stopping the engine
Normally, when Start/Stop is activated and the brakes are applied until the vehicle comes to a standstill, the engine will auto-stop automatically if the driver keeps the brake pedal depressed
.
To remind the driver that the enginehas been auto-stopped, the Start/Stopsymbol will illuminate in the instrumentpanel and remain on until the engine
restarts.
Auto-starting the engine
The engine restarts as soon as the driver relea- ses the brake pedal.
Deactivating Start/Stop
In certain situations (e.g., driv- ing in heavy, stop-and-go traf-fic), it may be preferable todeactivate Start/Stop. This is done by pressing the button in the center console.
The indicator light in the button will go out. Start/Stop will remain deactivated until the but- ton is pressed again or until the engine isswitched off and restarted by the driver.

All Wheel Drive (AWD)Your Volvo can be equipped with permanent All Wheel Drive, which means that power is distrib-uted automatically between the front and rearwheels.
Under normal driving conditions, most of the engine's power is directed to the front wheels.However, if there is any tendency for the frontwheels to spin, an electronically controlled cou-pling distributes power to the wheels that havethe best traction.
NOTE
The message AWD disabled Service
required will be appear in the information
display if an electrical fault should occur in the AWD system. A warning light will also illu-minate in the instrument panel. If this occurs,have the system checked by a trained andqualified Volvo service technician.

Hill Descent Control (HDC) – introduction
HDC is a type of automatic engine brake and makes it possible to increase or decrease thevehicle's speed on downhill gradients using onlythe accelerator pedal, without applying thebrakes. The brake system functions automaticallyto maintain a low and steady speed.
IntroductionNormally, when the accelerator pedal is released while driving down hills, the vehicle's speed slowsas the engine runs at lower rpm (the normalengine braking effect). However, if the downhillgradient becomes steeper and if the vehicle iscarrying a load, speed increases despite theengine braking effect. In this situation, the brakesmust be applied to reduce the vehicle's speed. HDC is particularly useful when driving down steep hills with rough surfaces, and where theroad may have slippery patches.
WARNING
HDC does not function in all situations, and is a supplementary braking aid. The driver hasfull responsibility for driving in a safe manner.

Hill Descent Control (HDC) – operation
Function
•HDC can be switched on and off with the button in the center console. An indicatorlight in the button illuminates when HDC isactivated.
• The indicator light
in the instrument
panel illuminates and a message is displayed when the system is controlling the vehicle'sspeed.
• HDC only functions when
first or reverse
gears are selected (
1 will be shown in the
instrument panel display when first gear is selected).
NOTE
HDC cannot be activated if the gear selector is the D position.
Using HDCHDC allows the car to roll forward at a maximum speed of 6 mph (10 km/h), and 4 mph (7 km/h)in reverse. However, the accelerator pedal can beused to select any speed that is possible in firstor reverse gears. When the accelerator pedal isreleased, speed is quickly reduced again to6 mph (10 km/h) or 4 mph (7 km/h), dependingon the gear selected, regardless of the hill's gra-dient. It is not necessary to apply the brakes.
• The brake lights illuminate automaticallywhen HDC is controlling the vehicle's speed.
• The driver can slow or stop the vehicle at anytime by applying the brakes.
HDC is deactivated when:
• The button on the center console is pressed
• A gear higher than first gear is selected
• D
is selected on vehicles with an automatic
transmission
HDC can be deactivated at any time. If this isdone while driving down a steep hill, the system'sbraking effect will decrease gradually.
NOTE
Engine response to pressure on the accelera- tor pedal may be slightly slower than normalwhen HDC is activated.

Driving through water
The vehicle should be driven with extreme cau- tion if it is necessary to drive through standingwater.
The vehicle can be driven through water up to a depth of approximately 13 in. (35 cm) at walkingspeed to help prevent water from entering thedifferential and the transmission. Water reducesthe oil's lubricating capacity and may shorten theservice life of these components.
• Take particular care when driving throughflowing water.
• Clean the electrical connections for trailerwiring after driving in mud or water.
• When driving through water, maintain lowspeed and do not stop in the water.
WARNING
•Avoid driving through standing or rushing water. Doing so can be dangerous and itmay also be difficult to determine theactual depth of the water.
• If water cannot be avoided, after drivingthrough the water, press lightly on thebrake pedal to ensure that the brakes arefunctioning normally. Water or mud canmake the brake linings slippery, resultingin delayed braking effect.
CAUTION
•Engine damage will occur if water is drawn into the air cleaner.
• If the vehicle is driven through waterdeeper than approximately 13 in.(35 cm), water may enter the differentialand the transmission. This reduces theoil's lubricating capacity and may shortenthe service life of these components.
• Damage to any components, the engine,transmission, turbo-charger, differential orits internal components caused by flood-ing, vapor lock or insufficient oil is notcovered under warranty.
• Do not allow the vehicle to stand in waterup to the door sills longer than absolutelynecessary. This could result in electricalmalfunctions.
• If the engine has been stopped while thevehicle is in water, do not attempt torestart it. Have the vehicle towed out ofthe water.

Engine and cooling system
Under special conditions, for example when driv- ing in hilly terrain, extreme heat or with heavyloads, there is a risk that the engine and coolingsystem will overheat.
Proceed as follows to avoid overheating the engine.
• Maintain a low speed when driving with atrailer up long, steep hills. For information,see Towing a trailer (p. 279)
• Do not turn the engine off immediately whenstopping after a hard drive.
WARNING
The cooling fan may start or continue to oper- ate (for up to 6 minutes) after the engine hasbeen switched off.
• Remove any auxiliary lights from in front of the grille when driving in hot weather condi-tions.
• Do not exceed engine speeds of 4500 rpm ifdriving with a trailer in hilly terrain. The oiltemperature could become too high.

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. 290). Check tire pressure (p. 297).
• 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. 303).

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 transmission's Sport mode mayincrease fuel consumption somewhat. Use the transmission's Drive (
D) position as often
as possible. For additional information about Sport mode, see Transmission – Geartronic(p. 254).
• 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.

WARNING
Driving with the tailgate open: Driving with
the tailgate open could lead to poisonous exhaust gases entering the passenger com-partment. If the tailgate must be kept open forany reason, proceed as follows:
• Close the windows
• Set the ventilation system control to airflow to floor, windshield and side windowsand the blower control to its highest set-ting.
Handling and roadholdingAt the specified curb weight your vehicle has a tendency to understeer, which means that thesteering wheel has to be turned more than mightseem appropriate for the curvature of a bend.This ensures good stability and reduces the riskof rear wheel skid. Remember that these proper-ties can alter with the vehicle load. The heavierthe load in the cargo area, the less the tendencyto understeer.
• Vehicle load, tire design and inflation pres-sure all affect vehicle handling. Therefore,check that the tires are inflated to the rec-ommended pressure according to the vehicleload. Loads should be distributed so thatcapacity weight or maximum permissible axleloads are not exceeded.

Towing a trailer When towing a trailer, always observe the legal requirements of the state/province.
NOTE
For the maximum trailer and tongue weights recommended by Volvo, see Weights (p. 372)
• All Volvo models are equipped with energy- absorbing shock-mounted bumpers. Trailerhitch installation should not interfere with theproper operation of this bumper system.
Trailer towing does not normally present any par-ticular problems, but take into consideration:
• Increase tire pressure to recommended fullpressure, see the tire inflation decal on thedriver's door opening.
• When your vehicle is new, avoid towing heavytrailers during the first 620 miles (1,000 km).
• Maximum speed when towing a trailer:50 mph (80 km/h).
• Engine and transmission are subject toincreased loads. Therefore, engine coolanttemperature should be closely watched whendriving in hot climates or hilly terrain. Use alower gear and turn off the air conditioner ifthe temperature gauge needle enters the redrange.
