Introduction
Start/Stop is a function that is available with certain engines/transmissions. It temporarilyswitches off the engine when the vehicle isnot moving, for instance in heavy traffic or ata traffic light to help reduce fuel consumption.
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 1
. The symbol in the
instrument panel will be displayed for several seconds when the engine starts and the indi-cator light in the On/Off button will remainilluminated while the function is activated. All of the vehicle's systems will function while the engine is auto-stopped, although the function of certain systems may reduced atthis time. For example, blower speed andhigh infotainment system volume may bereduced to help conserve the battery'scapacity.
Auto-stopping the engineNormally, when Start/Stop is activated andthe brakes are applied until the vehicle comesto a standstill, the engine will auto-stop auto-matically
if the driver keeps the brake pedal
depressed .
To remind the driver that the enginehas been auto-stopped, theStart/Stop symbol will illuminate inthe instrument panel and remain on
until the engine restarts.
If the ECO function* (see page 134) is activated, theengine may auto-stop beforethe vehicle comes to a com-plete standstill.
Auto-starting the engineThe engine restarts as soon as the driver releases the brake pedal.
Deactivating Start/StopIn certain situations (e.g.,driving in heavy, stop-and-gotraffic), it may be preferableto deactivate 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 button is pressed again or until the engine isswitched off and restarted by the driver.
Hill Start Assist (HSA)When starting on steep hills, HSA (see page 127) retains pressure on the brake pedalfor several seconds after the pedal has beenreleased in order to keep the vehicle at astandstill. The brakes will be released afterseveral seconds or when the driver pressesthe accelerator pedal.
1 Not when the engine is started using the optional Engine Remote Start feature, see page 124

Hill Descent Control (HDC)*

* Option/accessory, for more information, see Introduction.147
Introduction
Normally, when the accelerator pedal is released while driving down hills, the vehicle'sspeed slows as the engine runs at lower rpm(the normal engine braking effect). However, ifthe downhill gradient becomes steeper and ifthe vehicle is carrying a load, speed increasesdespite the engine braking effect. In this sit-uation, the brakes must be applied to reducethe vehicle's speed. HDC is a type of automatic engine brake and makes it possible to increase or decrease thevehicle's speed on downhill gradients usingonly the accelerator pedal, without applyingthe brakes. The brake system functions auto-matically to maintain a low and steady 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. Thedriver has full responsibility for driving in asafe manner.
Function
• HDC can be switched on and off with the button in the center console. An indicatorlight in the button illuminates when HDCis activated.
• The indicator light
in the instru-
ment panel illuminates and a message is displayed when the system is controllingthe vehicle's speed.
• 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 selec- tor is the D position.
Using HDC
HDC allows the car to roll forward at a maxi- mum speed of 6 mph (10 km/h), and 4 mph(7 km/h) in reverse. However, the acceleratorpedal can be used to select any speed that ispossible in first or reverse gears. When theaccelerator pedal is released, speed isquickly reduced again to 6 mph (10 km/h) or4 mph (7 km/h), depending on the gearselected, regardless of the hill's gradient. It isnot necessary to apply the brakes.
• The brake lights illuminate automatically when HDC is controlling the vehicle'sspeed.
• The driver can slow or stop the vehicle atany time by applying the brakes.
HDC is deactivated when:
• The button on the center console ispressed
• A gear higher than first gear is selected
• D
is selected on vehicles with an auto-
matic transmission
HDC can be deactivated at any time. If this is done while driving down a steep hill, the sys-tem's braking effect will decrease gradually.

Introduction
Volvo recommends the use of Volvo trailer hitches that are specially designed for thevehicle.
NOTE
See page 385 for the maximum trailer and tongue weights recommended by Volvo.
•Observe the legal requirements of the state/province in which the vehicles are
• All Volvo models are equipped withenergy-absorbing shock-mounted bump-ers. Trailer hitch installation should notinterfere with the proper operation of thisbumper system.
Trailer towing does not normally present any particular problems, but take into considera-tion: • Increase tire pressure to recommended full pressure. See the tire inflation tableon page 316.
• When your vehicle is new, avoid towingheavy trailers 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 cool-ant temperature should be closely watched when driving in hot climates orhilly terrain. Use a lower gear and turn offthe air conditioner if the temperaturegauge needle enters the red range.
• If the automatic transmission begins tooverheat, a message will be displayed inthe text window.
• Avoid overload and other abusive opera-tion.
• Hauling a trailer affects handling, durabil-ity, and economy.
• It is necessary to balance trailer brakeswith the towing vehicle brakes to providea safe stop (check and observe state/local regulations).
• 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 isnot being used.
WARNING
• Bumper-attached trailer hitches must not be used on Volvos, nor shouldsafety chains be attached to thebumper.
• Trailer hitches attaching to the vehiclerear axle must not be used.
• Never connect a trailer's hydraulicbrake system directly to the vehiclebrake system, nor a trailer's lightingsystem directly to the vehicle lightingsystem. Consult your nearest author-ized Volvo retailer for correct installa-tion.
• When towing a trailer, the trailer'ssafety wire must be correctly fastenedto the hole or hook provided in thetrailer hitch on the vehicle. The safetywire should never be fastened to orwound around the drawbar ball.
