Large animals
Optimal examples of what City Safety would interpret asa large animal: stationary or moving slowly and with clearbody contours.
For optimal performance, the system's functionfor detecting large animals (e.g. moose, horses,etc.) needs the clearest possible informationabout body contours. This entails being able todetect the animal straight from the side in combi-nation with normal movements for that animal.
If parts of the animal's body are not visible to thefunction's camera, the system will not be able todetect the animal.
City Safety can detect large animals even in darkconditions if they are illuminated by the vehicle'sheadlights.

WARNING
City Safety is supplementary driver support,but it cannot detect all large animals in all sit-uations and, for example, cannot see:
partially obscured larger animals.
larger animals seen from the front or frombehind.
running or fast moving larger animals.
larger animals if the contrast of the ani-mal's background is poor - warning andbrake interventions may then occur lateor not at all.
smaller animals such as cats and dogs.
The driver is always responsible for ensuringthat the vehicle is driven correctly and with asafety distance suitable for the speed.

Limitations of City Safety incrossing traffic
In certain situations, it may be difficult for CitySafety to help the driver avoid a collision withcrossing traffic.
For example:
on slippery roads when Electronic StabilityControl (ESC) is actively operating
if an approaching vehicle is detected at a latestage
if the oncoming vehicle is partially obstructedby another vehicle or object
if the oncoming vehicle's headlights are off
if the oncoming vehicle is moving erraticallyand e.g. suddenly changes lanes at a latestage.
NOTE
The function uses the vehicle's combinedcamera and radar unit, which has certain gen-eral limitations; see sections "Camera limita-tions" and "Radar sensor limitations".

Ignition modes
The vehicle's ignition can be put in variousmodes (levels) to make different functions availa-ble.
To enable the use of a limited number of func-tions when the engine is not running, the ignitioncan be put in one of three different levels: 0, Iand II. These levels are referred to as "ignitionmodes" in the Owner's Manual.
The following table shows which functions areavailable in each ignition mode:
Mode Functions
0The odometer, clock and tem-
perature gauge are illuminatedA.
The power* seats can beadjusted.
The power windows can be used.
The center display is activated
and can be usedA.
The infotainment system can be
usedA.
In this mode, the functions are availa-ble for a limited time and then switchoff automatically.
IThe panoramic roof, power win-dows, 12-volt electrical socket inthe passenger compartment,Bluetooth, navigation, phone,blower and windshield wipers canbe used.
The power seats can be adjusted.
The 12-volt electrical socket* inthe trunk can be used.
Electrical current will be takenfrom the battery in this ignitionmode.
Mode Functions
IIThe headlights illuminate.
Warning/indicator lights illumi-nate for 5 seconds.
A number of other systems areactivated. However, seat and rearwindow heating can only be acti-vated when the engine is running.
This ignition mode uses a lot ofcurrent from the battery andshould be avoided whenever pos-sible!

Battery drain
The electrical functions in the vehicle drain thebattery to varying degrees. Avoid using ignitionmode II when the engine is switched off. Useignition mode I instead, as this uses less electri-cal current.
Note that certain accessories may also drainpower 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 audiosystem.
–Charge the battery by starting the engineand let it run for at least 15 minutes (drivingcharges the battery faster than letting theengine idle).

Periodic maintenance helps minimize
emissions
NOTE
Refer to your Service and Warranty Book-let for a comprehensive service and main-tenance schedule up to 240,000 km(150,000 miles). This program containsinspections and services necessary forthe proper function of your vehicle andincludes components that affect vehicleemissions.
The Warranty and Service Records Infor-mation booklet also contains detailedinformation concerning the warrantiesthat apply to your vehicle.

On-board Diagnostic System
OBD II is part of your vehicle's computerizedengine management system. It stores diagnosticinformation about your vehicle's emission con-trols. It can light the Check Engine light (MIL) if itdetects an emission control "fault." A "fault" is acomponent or system that is not performingwithin an expected range. A fault may be perma-nent or temporary. OBD II will store a messageabout any fault.
Emission inspection readiness
How do states use OBD II for emission
inspections?
Many states connect a computer directly to avehicle's OBD II system. The inspector can thenread "faults." In some states, this type of inspec-tion has replaced the tailpipe emission test.

How can my vehicle fail OBD II emission
inspection?
Your vehicle can fail OBD II emission inspectionfor any of the following reasons:
If your Check Engine (MIL) light is lit, yourvehicle may fail inspection.
If your vehicle's Check Engine light was lit,but went out without any action on your part,OBD II will still have a recorded fault. Yourvehicle may pass or fail, depending on theinspection practices in your area.
If you had recent service that required dis-connecting the battery, OBD II diagnosticinformation may be incomplete and "notready" for inspection. A vehicle that is notready may fail inspection.

How can I prepare for my next OBD II
emission inspection?
If your Check Engine (MIL) light is lit or waslit but went out without service, have your
vehicle diagnosed and, if necessary, servicedby a qualified Volvo technician.
If you recently had service for a lit CheckEngine light, or if you had service thatrequired disconnecting the battery, a periodof driving is necessary to bring the OBD IIsystem to "ready" for inspection. Two half-hour trips of mixed stop-and-go/highwaydriving are typically needed to allow OBD II toreach readiness. Your Volvo retailer can pro-vide you with more information on planning atrip.
Maintain your vehicle in accordance with yourvehicle's maintenance schedule.
Owner maintenance
Periodic maintenance requirements and intervalsare described in your vehicle's Warranty andService Records Information booklet.
The following points can be carried out betweenthe normally scheduled maintenance services.

Each time the car is refueled:
Check the engine oil level.
Clean the windshield, windshield wipers,headlights, and taillights.

MAINTENANCE AND SERVICE
* Option/accessory.600
Unscrew the cover in the plastic covering.
Unscrew the expansion tank cap and fillcoolant as needed. The level should notexceed the yellow MAX mark inside theexpansion tank.
Put the components back in place in the reverseorder.

CAUTION
Do not ingest the contents. May causedamage to organs (kidneys).
Use premixed coolant according to Vol-vo's recommendations. If concentratedcoolant is used, make sure that the cool-ant mixture is 50% coolant and 50%water of acceptable quality.
Do not mix different types of coolant.
To help ensure sufficient corrosion pro-tection in the system, only use new cool-ant when replacing larger components inthe cooling system.
Never run the engine unless the coolingsystem is properly filled. An improperlyfilled cooling system could lead to hightemperatures and cracks in the cylinderheads.
High levels of chlorine, chlorides andother salts may cause corrosion in thecooling system.
