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 76
) 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.

Other limitations
WARNING
•Warnings and brake interventions can be triggered late or not at all if the traffic sit-uation or external influences prevent thecamera and radar unit from properlydetecting pedestrians, cyclists, large ani-mals or vehicles ahead of the vehicle.
• To be able to detect vehicles at night, itsfront and rear lights must work and illumi-nate clearly.
• The camera and radar unit have a limitedrange for pedestrians and cyclists – thesystem can provide effective warningsand brake interventions if the relativespeed is lower than 50 km/h (30 mph).For stationary or slow-moving vehicles,warnings and brake interventions areeffective at vehicle speeds of up to70 km/h (43 mph). Speed reduction forlarge animals is less than 15 km/h(9 mph) and can be achieved at vehiclespeeds over 70 km/h (43 mph). At lowerspeeds, the warning and brake interven-tion for large animals is less effective.
• Warnings for stationary or slow-movingvehicles and large animals can be disen-gaged due to darkness or poor visibility.
• Warnings and brake interventions for pedestrians and cyclists are disengagedat vehicle speeds over 80 km/h(50 mph).
• Do not place, affix or mount anything onthe inside or outside of the windshield, orin front of or around the camera andradar unit – this could disrupt camera-based functions.
• Objects, snow, ice or dirt in the area ofthe camera sensor can reduce the func-tion, disengage it completely or give animproper function response.
NOTE
The function uses the vehicle's camera unit, which has some general limitations – see thesection "Camera unit limitations".
NOTE
The function uses the vehicle's radar unit, which has some general limitations – see thesection "Radar unit limitations".

Brake Assist System
The brake enhancing system, Brake Assist
System (BAS), helps increase braking force andthereby reduce braking distance.
The system monitors the driver's braking habits and increases braking force when necessary.Braking force can be increased up to the point atwhich the ABS intervenes. The function is deacti-vated when pressure on the brake pedal isdecreased.
NOTE
When BAS is activated, the brake pedal will go down slightly more than usual. Press(hold) down the brake pedal as long as nec-essary. When the brake pedal is released, all braking ceases.

• Brakes (p. 405)
Braking on wet roads
Prolonged driving in heavy rain without braking may cause braking effect to be slightly delayedthe first time the brakes are applied.
This may also occur after washing the vehicle. It will then be necessary to apply greater pressureto the brake pedal. You should therefore maintaina greater distance to the vehicle ahead. Firmly apply the brakes after washing the vehicle or driving on wet roads. This helps warm up thebrake discs, enabling them to dry more quicklyand protecting them against corrosion. Considerthe current traffic situation when braking.

Braking assist after a collision In a collision in which the activation level is reached for the pyrotechnic seat belt tensionersor airbags, or if a collision with a large animal isdetected, the vehicle's brakes will be automati-cally activated. This function is intended to helpprevent or reduce the effects of any subsequentcollision.
After a serious collision, it may no longer be pos- sible to control and steer the vehicle. In order toavoid or mitigate a possible further collision witha vehicle or an object in the vehicle's path, thebrake assist system is activated automatically tohelp stop the vehicle safely. The brake lights and hazard warning flashers are activated during braking. When the vehicle has stopped, the hazard warning flashers will con-tinue to flash and the parking brake will beapplied. If braking is not appropriate, e.g. if there is a risk of being hit by passing traffic, the driver can over-ride the system by depressing the acceleratorpedal. This function assumes that the brake system is intact after a collision. Brake assist is part of the Rear Collision Warning and Blind Spot Information safety systems.

Transmission The transmission is part of the vehicle's driveline (power transmission) between the engine andthe drive wheels. The function of the transmis-sion is to change gears depending on speedand power needs.
The vehicle has an 8-speed automatic transmis- sion. The number of gears allows the engine'storque and power band to be effectively utilized.Two of the gears are overdrive gears that savefuel when driving at a constant engine speed.Manual shifting is also possible. The instrumentpanel shows the gear currently in use.
CAUTION
Check the operating temperature of the transmission to help avoid damage to any ofthe drive system components. If there is a riskof overheating, a warning symbol will appearin the instrument panel and a text messagewill be displayed. Follow the recommenda-tions given.
Symbols in the instrument panelIf a problem should occur with the transmission, a symbol and a message will appear in the instru-ment panel.

All Wheel Drive (AWD)
*
All-wheel drive, All Wheel Drive (AWD), also called four-wheel drive, means that power is dis-tributed to all four wheels, which improves trac-tion.
To achieve the best traction, power is automati- cally directed to the wheels that have the bestgrip. The system continuously calculates theneed for torque to the rear wheels, and canimmediately redistribute up to half of the engine'storque to the rear wheels. All-wheel drive also has a stabilizing effect at higher speeds. In normal driving conditions, mostof the engine's power is directed to the frontwheels. When the vehicle is stationary, all-wheeldrive is always activated in preparation for maxi-mum traction during acceleration. All-wheel drive reacts differently depending on which drive mode * is selected.

Emission controls
Three-way catalytic converter
•Keep your engine properly tuned. Certain engine malfunctions, particularly involving theelectrical, fuel or distributor ignition systems,may cause unusually high three-way catalyticconverter temperatures. Do not continue tooperate your vehicle if you detect enginemisfire, noticeable loss of power or otherunusual operating conditions, such as engineoverheating or backfiring. A properly tunedengine will help avoid malfunctions thatcould damage the three-way catalytic con-verter.
• Do not park your vehicle over combustiblematerials, such as grass or leaves, which cancome into contact with the hot exhaust sys-tem and cause such materials to ignite undercertain wind and weather conditions.
• Excessive starter cranking (in excess of oneminute), or an intermittently firing or floodedengine can cause three-way catalytic con-verter or exhaust system overheating.
• Remember that tampering or unauthorizedmodifications to the engine, the Engine Con-trol Module, or the vehicle may be illegal andcan cause three-way catalytic converter orexhaust system overheating. This includes:altering fuel injection settings or compo-nents, altering emission system components or location or removing components, and/orrepeated use of leaded fuel.NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxygen content of the exhaust gases. Readings are fedinto a control module that continuously monitorsengine functions and controls fuel injection. Theratio of fuel to air into the engine is continuouslyadjusted for efficient combustion to help reduceharmful emissions.
