Driving lane assistance provides vibrations in the steer- ing wheel7
.
Depending on the settings used, Lane Keeping Aid functions in different ways:
• Assistance type
Assist8
is activated: when
the vehicle approaches a traffic lane marker line, LKA will provide active steering assis-tance to help steer it back into the lane.
• Assistance type
Warning8
is activated: if the
vehicle is moving out of its traffic lane, an audible signal and/or vibrations in the steer-ing wheel will be provided.
NOTE
If the turn signal is used, Lane Keeping Aid will not provide an alert or steering assis-
tance.
WARNING
Lane Keeping Aid is only intended to assist the driver and does not function in all driving,weather, traffic or road conditions. As the driver, you have full responsibility for operating the vehicle in a safe manner.
Steering assistanceIn order for LKA's steering assistance to function, the driver's hands must be on the steering wheel,which the system monitors continuously.
If the driver's hands are not onthe steering wheel, this symbolwill illuminate in the instrumentpanel and the following mes-sage will be displayed:
•Lane Keeping Aid – Apply steering
If the driver does not begin to steer the vehicle, the symbol will illuminate again, an audible signal will sound and the following message will be dis-played:
•
Lane Keeping Aid – Standby until
steering applied
If the driver still does not begin to steer the vehi- cle, LKA will go into standby mode. The functionwill not become available again until the driveractively steers the vehicle
Traffic lane assistance does not react
The traffic lane assistance system does not intervene in sharp curves
In certain cases, such as during active driving or if the turn signal is used, the traffic lane system will not react if the vehicle crosses a lane marker
line.
7 The level of vibrations varies; the farther the vehicle is over a lane marker line, the greater the number of vibrations:

Backing up
Location of the rear Park Assist Camera (generic illus- tration)
The rear camera shows a wide area behind the vehicle and on certain models, part of the bumperand the trailer hitch (if installed) will be visible. Some objects on the screen may appear to “lean” slightly, which is normal.
WARNING
People/objects/obstructions displayed on the center console screen may be closer to thevehicle than they appear.
Front camera
Location of the front Park Assist Camera (generic illus- tration)
The front camera is located behind the grill and can be useful when driving off in areas with lim-ited visibility (hedges, bushes, etc). It is active atspeeds up to approx. 16 mph (25 km/h) and isautomatically turned off when the vehicleexceeds this speed. However, if the vehicle's speed does not exceed 30 mph (50 km/h) and its speed goes under14 mph (22 km/h) within 60 seconds after thecamera has been switched off, the front camerawill reactivate.

Driving on wet or salted roadsProlonged driving on wet or salted roads can affect brake function and increase stopping dis-tance. Be sure to keep a safe distance to thevehicle ahead when driving under these condi-tions.
Brake pad inspection
On vehicles equipped with a jack *, the condition
of the brake pads can be checked by raising thevehicle and performing a visual inspection of thebrake pads.
WARNING
• If the vehicle has been driven immediately prior to a brake pad inspection, the wheelhub, brake components, etc., will be veryhot. Allow time for these components tocool before carrying out the inspection.
• Apply the parking brake and put the gear selector in the Park (
P) position.
• Block the wheels standing on the ground, use rigid wooden blocks or large stones.
WARNING
•
Use the jack intended for the vehicle when changing a tire. For any other job,use stands to support the vehicle.
• The jack should be kept well-greased andclean, and should not be damaged.
• Be sure the jack is on a firm, level, non-slippery surface.
• No objects should be placed between thebase of jack and the ground, or betweenthe jack and the attachment bar on thevehicle.
• The jack must correctly engage the jackattachment.
• Never allow any part of your body to beextended under a vehicle supported by ajack.

Brake assist system The Brake Assist System (BAS) increases brak- ing force, thereby helping reduce braking dis-tance.
The system monitors the driver's braking habits and increases braking force when necessary.Brake force can be increased up to the point atwhich the ABS system is activated. The functionis deactivated when pressure on the brake pedaldecreases.

Braking effect after a collision
In certain types of collisions, the vehicle's brakes are applied to help prevent or mitigate a secon-dary collision.
Maintaining control of the vehicle after a collision may be difficult. To help avoid or mitigate theeffect of a secondary collision, the brakes areapplied automatically to help bring the vehicle toa stop. The brake lights and hazard warning flashers will be activated and the flashers will remain on afterthe vehicle has come to a standstill. The parkingbrake will then be applied automatically. In a situation where stopping the vehicle may not be desirable, the driver can override this systemby pressing the accelerator pedal. This feature can only function if the brake system is intact after the collision.

Hill Start Assist
Hill Start Assist (HSA) helps prevent the vehicle from rolling backwards when starting up a hill. Ifyou are backing up a hill, HSA helps prevent thevehicle from rolling forward.
HSA makes it easier to start or back up on a hill by retaining pressure on the brake pedal for sev-eral seconds after the pedal has been released inorder to keep the vehicle at a standstill. The brakes will be released after several seconds or when the driver presses the accelerator pedal. HSA is available even if the Auto-hold braking function is turned off.

• Consider your destination. If you will be driv-ing through an area where snow or ice arelikely to occur, consider using snow tires.
Driving economically
Better driving economy can 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 Eco function can helpimprove fuel economy.
• Do not exceed posted speed limits.
• Avoid carrying unnecessary items (extra load)in the vehicle.
• Maintain correct tire pressure. Check tirepressure regularly (when the tires are cold). •
Use tires recommended by Volvo for yourvehicle.
• 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.
Handling and roadholding
• 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 that

capacity weight or maximum permissible axle loads are not exceeded.
• At the specified curb weight your vehicle hasa tendency to understeer, which means thatthe steering wheel has to be turned morethan might seem appropriate for the curva-ture of a bend. This ensures good stabilityand reduces the risk of rear wheel skid.Remember that these properties can alterwith the vehicle load. The heavier the load inthe cargo compartment, the less the ten-dency to understeer.

Driving through standing 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 17.7 in. (45 cm) at walk-ing speed. Be particularly careful when drivingthrough flowing water. • Take particular care when driving through flowing water.
• After driving through water, apply the brakesand check that they are functioning correctly.
• 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.
• Avoid driving through salt water if at all pos-sible to help avoid the risk of corrosion.
CAUTION
• Engine damage will occur if water is drawn into the air cleaner.
• 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.
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.

Towing recommendations
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.
Towing your vehicle behind another vehicle
1. After securely attaching the towing line to both vehicles, put the gear selector in posi- tion N and release the parking brake.
2. Put the ignition in mode II by turning the
start knob to START (without depressing
the brake pedal) and hold it in this position
for approx. 4 seconds. Release the knob.
3. Put the gear selector in position N and
release the parking brake.
4. The towing vehicle can now begin driving.
5. 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.
6. Be prepared to apply the brakes to stop the vehicle being towed.
CAUTION
General towing precautions:
• If the vehicle's battery is dead, an auxiliary battery will be necessary to provide cur-rent for releasing the electric parkingbrake and to move the gear selector from the
P position to N. If this is not possible,
use the shiftlock override procedure tomanually release the gear selector from P
and move it 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.
WARNING
• When the vehicle is being towed, the igni- tion should be in mode
II (in mode I, all of
the vehicle's airbags are deactivated).
• The remote key must remain inside the vehicle.
• The power brakes and power steering willnot function when the engine is not run-ning. Approximately 5 times more pres-sure will be required on the brake pedaland the steering wheel will be considera-bly harder to turn.
• The towing eyelets must not be used forpulling the vehicle out of a ditch or forany similar purpose involving severestrain.
