Adjusting set speed for driver support
It is possible to adjust set speeds for the Adaptive Cruise Control * and Pilot Assist *
functions.
: Increases the set speed.
: Reduces the set speed.
Set speed.
–Change a set speed by pressing the
(1) or (2) buttons briefly or by pressing
and holding them:
Brief
press: Each press changes the
speed in +/- 5 km/h (+/- 5 mph) incre- ments.
Press
and hold: Release the button
when the set speed indicator (3) hasmoved to the desired speed.
NOTE
For vehicles without Adaptive Cruise Con- trol *, speed instead increases by +/- 1km/h
(+/- 1 mph) each time the button is pressed.
The most recently set speed will be stored.
If speed is increased by depressing the accel- erator pedal while pressing the
(1) button
on the steering wheel, the vehicle's speed when the button is pressed will be stored as the set speed. Temporarily increasing speed using the accel- erator pedal, e.g. when passing another vehi-cle, will not affect the setting. The vehicle willreturn to the set speed when the acceleratorpedal is released.
Automatic transmission
The driver support functions can follow another vehicle at speeds from a standstill upto 200 km/h (125 mph). Pilot Assist can provide steering assistance from near-stationary speeds up to 140 km/h(87 mph). The lowest speed that can be set is 30 km/h (20 mph). When following another vehicle,ACC can monitor that vehicle's speed andslow your own vehicle down to a standstill,but it is not possible to set speeds lower than30 km/h (20 mph).

Driver Alert Control limitations
Driver Alert Control (DAC) functionality may be reduced in certain situations.
In certain situations, the system may provide a warning even if it has not detected a change indriving behavior, e.g.: in strong crosswinds
on grooved road surfaces.
WARNING
In certain cases, driving behavior might not be affected despite the driver's fatigue – when using the Pilot Assist
* function –
resulting in the driver not getting a warning from DAC. It is therefore very important to always stop and take a break at the slightest signof fatigue, regardless of whether the func-tion has issued a warning or not.
NOTE
The function uses the vehicle's camera and radar sensor, which has certain generallimitations.

Lane Keeping Aid
Lane Keeping Aid (LKA 85
) is designed to
actively steer the vehicle on freeways, high- ways and other major roads to help the driverreduce the risk of the vehicle unintentionallyveering out of the lane.
Lake Keeping Aid steers the vehicle back into the lane and/or alerts the driver using vibra-tions in the steering wheel. Lane Keeping Aid is active at speeds between 65–200 km/h (40–125 mph) on roads withclearly visible traffic lane marker lines. On narrow roads, the function may be unavail- able and go into standby mode. The functionwill become available again when the roadbecomes sufficiently wide.
A camera monitors the road/traffic lane's marker lines.
Lane Keeping Aid steers the vehicle back into its lane.

Braking assist after a collision
In a collision in which the activation level is reached for the pyrotechnic seat belt tension-ers or airbags, or if a collision with a large ani-mal is detected, the vehicle's brakes will beautomatically activated. This function isintended to help prevent or reduce the effectsof any subsequent collision.
After a serious collision, it may no longer be possible to control and steer the vehicle. Inorder to avoid or mitigate a possible furthercollision with a vehicle or an object in the vehi-cle's path, the brake assist system is activatedautomatically to help stop the vehicle safely. If braking is not appropriate, e.g. if there is a risk of being hit by passing traffic, the drivercan override the system by depressing theaccelerator pedal. This function assumes that the brake system is intact after a collision.

Transmission
The transmission is part of the vehicle's drive- line (power transmission) between the engineand the drive wheels. The function of thetransmission is to change gears dependingon speed and power needs.
The vehicle has an 8-speed automatic trans- mission and an electric motor for rear-wheeldrive. The number of gears allows the engine'storque and power band to be effectively uti-lized. Two of the gears are overdrive gears thatsave fuel when driving at a constant enginespeed. Manual shifting is also possible. Theinstrument panel shows the gear currently inuse.

Gear selector positions for automatic transmissions
With an automatic transmission, a suitable gear is selected automatically according tocurrent speed and power requirements.
Selecting gearsThe gear selector is a shift-by-wire selector, where shifting is done electronically instead ofmechanically. This makes shifting easier andthe gear positions more distinct.
Gear selector and gear selector positions overview.
Change gear position by pushing the spring- loaded gear selector forward or rearward, or tothe side for manual shifting.

Preparing for a long trip
It is important to have the vehicle's systems and equipment checked carefully before driv-ing long distances.
Check that
the engine is running properly and that fuel consumption is normal
there are no leaks (fuel, oil or other fluid)
the brake pedal is functioning properly
all lights are working
‒ adjust the head-
light height if the vehicle is carrying aheavy load
tire tread depth and air pressure are atcorrect levels. Change to snow tires whendriving in areas where there is a risk ofsnowy or icy roads
the start battery is sufficiently charged
the wiper blades are in good condition

Winter driving
It is important to check the vehicle before driving in cold/snowy conditions to makesure it can be driven safely.
Before the cold season arrives: Make sure the engine coolant contains 50% antifreeze. This mixture helps pro-tect the engine from frost erosion down toapprox. –35 °C (–31 °F). Do not mix dif-ferent types of antifreeze as this couldpose a health risk.
Keep the fuel tank well filled to preventcondensation from forming.
Check the viscosity of the engine oil. Oilwith low viscosity (thinner oil) improvescold-weather starting and reduces fuelconsumption when driving with a coldengine.
CAUTION
Low-viscosity oil should not be used with hard driving or in hot weather.
Check the condition and charge level of the start battery. Cold weather placesgreater demands on the start battery andreduces its capacity.
Use washer fluid containing antifreeze tohelp prevent ice from forming in thewasher fluid reservoir.
Slippery driving conditionsTo help optimize traction and roadholding,Volvo recommends using snow tires on allwheels whenever there is a risk of snow or iceon the road.
NOTE
Certain countries require use of winter tires by law. Not all countries permit the use ofstudded tires.
Practice driving on slippery surfaces under controlled conditions to learn how the vehiclereacts.

Limitations
Main channel vs. sub-channels (FM only)
: The main channel is the only chan-
nel that can receive in hybrid mode (bothdigital and analog). If a frequency has sub-channels, they are broadcast in digitalmode only. The main FM channel will bedisplayed as, for example, "WRIF-FMHD1". The sub-FM channels will be dis-played as"WRIF-FM HD2", "WRIF-FMHD3", etc.
Reception coverage area
: Due to current
IBOC transmitter power limitations, thereception coverage area in digital mode issomewhat more limited than the station'sanalog coverage area. Be aware that, likeall radio transmission technology, terrain,time of day, vegetation and buildings canhave a positive or negative effect on radioreception.
Analog to digital/digital to analogblending
: Analog to digital blending will
occur as the signal strength reaches a pre-set threshold in the receiver. This will benoticeable in fringe areas (areas with weakreception) and is normal.
NOTE
There may be a noticeable difference in sound quality when a change from ana-logue to digital or digital to analogueoccurs, such as:
Volume increase or decrease
Equalizer settings, i.e., Bass/ Mid-range/Treble cut or boost
Time alignment (Digital program mate-rial in extreme cases can be as muchas 8 seconds behind the analogue).This will noticeable as a "stuttering"effect.
The above items are dependant on thebroadcaster's equipment settings anddo not indicate a fault in the vehicle'sradio receiver or antenna systems .
