Using the windshield and headlight washers The windshield and headlight washers are designed to clean the windshield and head-lights. Use the right-side steering wheel leverto start the windshield and headlight wash-ers.
Starting the windshield and headlight washers
Washing function, right-hand steering wheel lever.
–Move the right-hand steering wheel lever toward the steering wheel to start thewindshield and headlight washers.
> After the lever is released, the wipers
make several extra sweeps.
CAUTION
Avoid activating the washer system when it is frozen or the fluid reservoir is empty.Otherwise, there is a risk of damaging thepump.
Headlight washer *To save washer fluid, the headlights are washed automatically according to a definedinterval when the headlights are on.
Reduced washingWhen there is about 1 liter (1 qt) of washer fluid left in the reservoir and the Washer fluid
Level low, refill message is displayed in the
instrument panel together with the
sym-
bol, the washer fluid supply to the headlights is cut off. This is to prioritize windshield clean-ing and visibility through it. The headlights areonly washed if high or low beam is on.

CauseAction
Water or snow is spraying/swirling up and blocking the radar signals or the camera's range of visibility. No action. Very wet or snow-covered roads may sometimes prevent the cam-era/radar sensor from functioning.
There is dirt between the inside of the windshield and the cam-era/radar sensor. Consult a workshop to have the area of the windshield on the inside of the cam-era's casing cleaned. An authorized Volvo workshop is recommended.
Bright sunlight. No action. The camera/radar sensor will reset automatically when lighting con-ditions improve.
High temperatures
If the temperature in the passenger compart- ment is very high, the camera/radar sensorwill switch off temporarily forapprox. 15 minutes after the engine is startedto protect its electronic components. Whenthe temperature has cooled sufficiently, thecamera/radar sensor will automatically restart.
Damaged windshield
NOTE
Failure to take action could result in reduced performance for the driver supportsystems that use the camera and radarunit. It could cause functions to bereduced, deactivated completely or to pro-duce an incorrect function response.
To avoid the risk of malfunction of the driver support systems that use the radar sensor, thefollowing also apply:
If there are cracks, scratches or stonechips on the windshield in front of any ofthe camera and radar sensor "windows"and this covers an area ofabout 0.5 × 3.0 mm (0.02 × 0.12 in.) ormore, contact a workshop to have the windshield replaced 54
.
Volvo advises
against repairing cracks,
scratches or stone chips in the area in front of the camera and radar sensor – theentire windshield should instead bereplaced.
Before replacing the windshield, contact a workshop 54
to verify that the right wind-
shield has been ordered and installed.
The same type of windshield wipers or wipers approved by Volvo should be usedfor replacement.
If the windshield is replaced, the cameraand radar sensor must be recalibrated by a workshop 54
to help ensure proper func-
tioning of all of the vehicle's camera and radar-based systems.
Radar
Vehicle speed
The radar sensor's ability to detect a vehicle ahead is significantly reduced if the speed ofthe vehicle ahead differs greatly from yourvehicle's speed.
54 An authorized Volvo workshop is recommended.

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.

Driving through standing water
It may be necessary to drive the vehicle through standing water, e.g. deep puddles orflooding on the road. This must be done withgreat caution.
To help prevent damage to the vehicle when driving through water:
Do not drive in water higher than the floorof the vehicle. If possible, check the depthof the water at its deepest point beforedriving through it. Be particularly carefulwhen driving through flowing water.
Always select the
Off Road drive mode
before driving in water to ensure the gaso- line engine is running.
Do not drive faster than walking speed.
Do not stop the vehicle in the water. Drivecarefully forward or back the vehicle out ofthe water.
Remember that waves created by passingvehicles could cause the water level to riseabove the vehicle's floor level.
Avoid driving through salt water to helpavoid the risk of corrosion.
CAUTION
Parts of the vehicle (e.g. engine, transmis- sion, driveline, electrical components, etc.)can be damaged if the vehicle is driventhrough water higher than its floor level.Damage to any components caused byflooding, vapor lock or insufficient oil is notcovered under warranty. If the engine stalls while the vehicle is in water, do not attempt to restart it. Havethe vehicle towed on the bed of a towtruck to a workshop - an authorized Volvoworkshop is recommended.
CAUTION
Because it can be difficult to determine the water depth, Volvo recommends not driv-ing through standing or running water. Thedriver is always responsible for operatingthe vehicle in a safe manner and adheringto all applicable laws and regulations.
When you have passed the water, press lightly on the brake pedal and check that the brakesare functioning properly. Water, mud, slush,etc. can make the brake linings slippery,resulting in delayed braking effect. If the vehicle is equipped with a trailer cou- pling contact, clean the contact after driving inwater or mud.

Battery drain
The electrical functions in the vehicle drain the battery to varying degrees. Avoid usingignition mode II when the engine is switched
off. Use ignition mode I instead, as this uses
less electrical current.
Note that certain accessories may also drain power from the electrical system. Do not usefunctions that use a lot of electrical currentwhen the engine is turned off. Examples ofsuch functions are: blower
headlights
windshield wipers
audio system (especially at high volume).
If the starter battery voltage is low, a message is shown in the driver display. The vehicle'senergy-saving function will then turn off orreduce certain functions, such as the blowerand/or the audio system.
–Charge the battery by starting the engine and let it run for at least 15 minutes (driv-ing charges the battery faster than lettingthe engine idle).

CAUTION
The charging point of the vehicle is only intended for jump starting the vehicle inquestion. The charging point is notintended for jump-starting another vehicle.Using the charging point to start anothervehicle could cause a fuse to blow, whichwould cause the charging point to stopworking.
If a fuse has blown, 12 V Battery Fuse failure
Service required will be displayed in the instrument panel. Volvo recommends contact- ing an authorized Volvo workshop. To avoid short circuits or other damage, the following steps are recommended when jumpstarting the battery:

Calibrating the compass *
The globe is divided into 15 magnetic zones. The compass 27
should be calibrated if the
vehicle is driven from one zone to another.
1. Stop the vehicle in a large, open area away from steel constructions and high-voltage power lines.
2. Start the engine and switch off all electri- cal equipment (climate system, wipers,etc.) and make sure all doors are closed.
NOTE
Calibration may fail or not even be initiated if electrical equipment is not turned off.
3. Hold the button on the bottom of the rear-view mirror pressed for about 3 seconds (using e.g. a paper clip). The number of thecurrent magnetic zone is shown.

press and hold the button on the under- side of the rearview mirror for approx.
6 seconds until
C is displayed.
6. Drive slowly in a circle at a speed of no more than 10 km/h (6 mph) until a com- pass direction is shown in the display. Thisindicates that calibration is complete.Drive in a circle two more times to fine-tune the calibration. 7.
Vehicles with heated windshields *: If
Cis shown in the display when the wind- shield heating function is activated, per-form step 6 above with the heating func-tion on.
8. Repeat the above procedure as needed.
