Recommended maintenance for theradar sensor
In order for the camera/radar sensor to function properly, the area of the windshield in front of theunit must be kept free of dirt, ice, snow, etc. andshould be washed regularly with water and carwashing detergent.
NOTE
Dirt, ice and snow covering the camera and radar unit reduce their function and can makemeasurement impossible. It could cause functions to be reduced, deac- tivated completely or produce an incorrectfunction response.

City Safety limitations
City Safety functionality may be reduced in cer- tain situations.
Surroundings
Low objects
Hanging objects, such as flags for overhanging loads or accessories such as auxiliary lights orfront protective grids that extend beyond theheight of the hood, may limit City Safety function-ality.
Slippery road conditions
The extended braking distance on slippery roads may reduce City Safety's capacity to help avoid acollision. In these types of situations, the Anti-lock Braking System and Electronic Stability Con- trol (ESC 77
) will help provide optimal braking
power with maintained stability.
Backlighting
The visual warning signal in the windshield may be difficult to detect in bright sunlight, if there arereflections, or if the driver is wearing sunglassesor not looking straight ahead.
Heat
If the temperature in the passenger compartment is high due to e.g. bright sunlight, the visual warn-ing signal in the windshield may be temporarilydisabled.
Camera and radar sensor's field of vision
The camera's field of vision is limited and in cer- tain situations, it may be unable to detect pedes-trians, large animals, cyclists or vehicles, or it maydetect them later than expected. Vehicles that are dirty may be detected later than clean vehicles, and in dark conditions, motorcy-cles may be detected late or not at all. If a text message displayed in the instrument panel indicates that the camera/radar sensor isobstructed, it may be difficult for City Safety todetect pedestrians, large animals, cyclists, vehi-cles or lane markings in front of the vehicle. CitySafety functionality may therefore be reduced. Text messages may not be displayed for all situa- tions in which the windshield sensors areblocked. The driver must therefore always keepthe windshield in front of the camera/radar sen-sor clean.
CAUTION
Maintenance and replacement of City Safety components may only be performed by aworkshop – an authorized Volvo workshop isrecommended.
Driver intervention
Backing up
City Safety is temporarily deactivated when the vehicle is backing up.
Low speed
City Safety is not activated at very low speeds under 4 km/h (3 mph). The system will thereforenot intervene in situations in which your vehicle isapproaching another vehicle very slowly, such aswhen parking.
Active driver
Action by the driver always has priority. City Safety will therefore not react or will react at alater stage with a warning or intervention in situa-tions in which the driver is clearly steering andoperating the accelerator pedal, even if a collisionis unavoidable. An active and aware driving style may therefore delay collision warnings and intervention in order to minimize unnecessary warnings.

Parking on a hill
Always use the parking brake when parking on a hill.
WARNING
Always apply the parking brake when parking on an incline. Selecting a gear or putting the automatic transmission in P may not be suffi-
cient to keep the vehicle stationary in all sit- uations.
If the vehicle is pointing uphill: • Turn the front wheels so they are pointing away from
the curb.
If the vehicle is pointing downhill:
• Turn the front wheels so they are pointingtoward
the curb.
Heavy load uphill
Heavy loads, such as a trailer, could cause the vehicle to roll backward when the parking brakeis released automatically on steep uphill gradi-ents. To help avoid this, pull the control upwardwhile you are driving away. Release the controlwhen the vehicle gains traction.

Parking brake malfunction
If you are unable to deactivate or activate the parking brake after several attempts, contact anauthorized Volvo workshop.
A audible warning signal will sound if the parking brake is applied while the vehicle is being driven. If the vehicle must be parked before the problem is rectified, turn the wheels as when parking on an incline and put the gear selector in P.
Low battery charge levelIf the battery charge level is too low, it will not be possible to apply or release the parking brake.Connect an auxiliary battery to the vehicle if thebattery is discharged.
Replacing brake padsDue to the design of the electric parking brake,the rear brake pads must be replaced by a work-shop. An authorized Volvo workshop is recom-mended.

Battery drain The electrical functions in the vehicle drain the battery to varying degrees. Avoid using ignitionmode II when the engine is switched off. Use
ignition mode I instead, as this uses less electri-
cal current.
Note that certain accessories may also drain power from the electrical system. Do not usefunctions that use a lot of electrical current whenthe engine is turned off. Examples of such func-tions are:
• blower
• headlights
• windshield wipers
• audio system (especially at high volume).
If the starter battery voltage is low, a message isshown in the driver display. The vehicle's energy-saving function will then turn off or reduce certainfunctions, such as the blower and/or the audio system.
–Charge the battery by starting the engine and let it run for at least 15 minutes (drivingcharges the battery faster than letting theengine idle).

Jump starting using another battery
If the start battery is discharged, current from another battery can be used to start the vehicle.
Jumper cable connecting points.
To avoid short circuits or other damage, the fol- lowing steps are recommended when jump star-ting the battery using another battery: 1. Put the ignition in mode 0.
2. Make sure the auxiliary battery (the battery used to jump start the discharged battery) has a voltage of 12 volts.
3. If the auxiliary battery is in another vehicle, turn off that vehicle's engine and make surethat the vehicles are not touching each other. 4. Clamp the red jumper cable onto the auxiliary
battery's positive (+) terminal (1).
CAUTION
Connect the jump cable carefully to prevent short circuits with other components in theengine compartment.
5. Fold back the cover over your vehicle's posi-tive (+) jump start terminal (2).
6. Clamp the other end of the red jumper cable to your vehicle's positive (+) jump start termi- nal (2).
7. Clamp the black jumper cable onto the auxili- ary battery's negative (-) terminal (3).
8. Clamp the other end of the black jumper cable to your vehicle's negative (-) groundpoint (4).
9. Make sure the jumper cables are securely attached to help prevent sparks while jumpstarting.
10. Start the engine of the assisting vehicle and let it run for a few minutes at a higher idlingspeed than normal, about 1500 rpm.

Towing using a towline
This section refers to one vehicle being towed behind another using a towline.
Before towing another vehicle, check applicable speed limit regulations.
Preparations and towing
CAUTION
Note that the vehicle must always be towed with the wheels rolling forward.
• Do not tow a vehicle with automatictransmission at a speed greater than80 km/h (50 mph) or for a distancegreater than 80 km (50 miles).
WARNING
•
Ignition mode
II must be active – all air-
bags are deactivated in ignition mode I.
• Always have the remote key in the vehicle when it is towed.
WARNING
The brake and steering servos do not work when the engine is off – it takesabout 5 times more pressure on the brakepedal and steering requires much more effortthan normal. 1. Turn on the hazard warning flashers.
2. Attach the towline to the towing eyelet.3.
Put the vehicle in ignition mode II – without
pressing the brake pedal, turn the start knob clockwise and hold it there for about4 seconds. Release the knob, which willautomatically return to its original position.
4. Move the gear selector to neutral ( N) and
release the parking brake. If the battery charge level is too low, it may not be possible to release the parking brake.Connect an auxiliary battery to the vehicle ifthe battery is discharged.
> The towing vehicle can now start driving.
5. Keep the towline taut when the towing vehi- cle slows down by applying light pressure to the brake pedal. This will help avoid jarringmovements.
6. Be prepared to apply the brakes to stop the vehicle.
Jump startingDo not tow the vehicle to start the engine. Use anauxiliary battery if the start battery's charge levelis so low that the engine cannot be started.
