Collision warning – troubleshooting
Fault tracing and actionsIf the message Windscreen Sensors blockedis displayed, this means that the camera isobscured and cannot detect pedestrians, cyclists, vehicles or road marker lines in front of the vehi-cle. This, in turn, means that Pedestrian and Cyclist Detection with Full Auto Brake, Driver Alert Con-trol, Lane Departure Warning or Lane KeepingAid will not have full functionality. The table lists possible causes for this message being displayed, and suitable actions.
Cause
Action
The surface of the windshield in front of the camera is dirty or covered with ice or snow. Clean or clear the section of the windshield in front of the camera.
Fog, heavy rain or snow is interfering with the function of the camera. No action possible. Heavy precipitation may affect the function of the cam- era.
The surface of the windshield is clean but the message remains in the display. Wait a short time. It may take several minutes for the camera to register vis- ibility.
The surface between the inside of the windshield and the camera is dirty. Contact an authorized Volvo retailer or service technician to have this sur- face cleaned.

Shiftlock
When P has been selected, the transmission is
mechanically blocked in this position. The brake pedal must be depressed and the ignition must be in at least mode II (see Ignition modes
(p. 74)) before the gear lever can be moved fromthe P position.
WARNING
Always apply the parking brake when the vehicle is parked, particularly when parking on a hill. The transmission's P mode may not be
able to keep the vehicle stationary if it is parked on an incline.
Press the control to apply the parking brake, see Parking brake – general information (p. 271).
CAUTION
The vehicle must be stationary when position P is selected.
Gear indicatorThe gear currently being used is displayed on the right side ofthe instrument panel. The " S" symbol turns orange if
Sport mode is being used.
Reverse: position RThe vehicle must be stationary when position R is
selected.
Neutral: position NNo gear is engaged and the engine can be started with the gear selector in this position.Apply the parking brake if the vehicle is stationary with the gear selector in position N. In order to
move the gear selector from the N position, the
brake pedal must be depressed and the ignitionmust be in at least mode II.
Drive: position DD is the normal driving position. The car automat-
ically shifts between the various forward gears, based on the level of acceleration and speed.The car must be at a standstill when shifting from position R to position D.

Transmission – Geartronic
Geartronic allows you to manually shift among your vehicle's forward gears. The manual posi-tion ( +S–) can be selected at any time.
Geartronic: manual shifting (+S–)To shift gears manually, move the gear selector to the side from D toward
+S– . The +S– symbol in the instrument
panel will change from white to
orange and the number of the gear currently
being used (
1, 2, 3, etc.) will be displayed (see
the following illustration) 5
.
• To return to automatic shifting mode from +S–
, move the gear selector to the side
toward D.

This option indicates when to shift up or down to help conserve fuel. A white arrow will appearabove or below the number of the current gear toprompt the driver to shift up or down.
While driving
•
If you select the manual shifting position while driving, the gear that was being used inthe Drive position will also initially beselected in the manual shifting position.
• Move the gear selector forward (toward
+) to
shift to a higher gear or rearward (toward –)
to shift to a lower gear.
• If you hold the gear selector toward "
–", the
transmission will downshift one gear at atime and will utilize the braking power of the engine. If the current speed is too high forusing a lower gear, the downshift will notoccur until the speed has decreased enoughto allow the lower gear to be used.
• If you slow to a very low speed, the transmis-sion will automatically shift down.
Shiftlock: Neutral (N)
If the gear selector is in the
N position and the
vehicle has been stationary for at least 3 seconds (irrespective of whether the engine is running)then the gear selector is locked. In order to move the gear selector from N to
another gear position, the brake pedal must be depressed and the ignition must be in at least position II, see Ignition modes (p. 74).

If Sport mode is being used, the symbol will change to "S".

Brake pad inspection
On vehicles equipped with a jack *, the condition
of the brake pads can be checked by raising the vehicle (see Changing a wheel – removing wheel(p. 293) for information about using the jack andremoving a wheel) and performing a visualinspection of the brake 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.
Power brakes function only when the engine is running
The power brakes utilize vacuum pressure which is only created when the engine is running. Neverlet the vehicle roll to a stop with the engineswitched off. If the power brakes are not working, considerably higher pressure will be required on the brakepedal to compensate for the lack of power assis-tance. This can happen for example when towingyour vehicle or if the engine is switched off when the vehicle is rolling. The brake pedal feels harderthan usual.
Water on brake discs and brake pads
affects braking
Driving in rain and slush or passing through anautomatic car wash can cause water to collect onthe brake discs and pads. This will cause a delayin braking effect when the pedal is depressed. Toavoid such a delay when the brakes are needed,depress the pedal occasionally when drivingthrough rain, slush, etc. This will remove the waterfrom the brakes. Check that brake applicationfeels normal. This should also be done afterwashing or starting in very damp or cold weather.
Severe strain on the brake systemThe brakes will be subject to severe strain whendriving in mountains or hilly areas, or when towinga trailer. Vehicle speed is usually slower, whichmeans that the cooling of the brakes is less effi-cient than when driving on level roads. To reducethe strain on the brakes, shift into a lower gearand let the engine help with the braking. Do notforget that if you are towing a trailer, the brakeswill be subjected to a greater than normal load.
Cleaning the brake discsCoatings of dirt and water on the brake discsmay result in delayed brake function. This delay isminimized by cleaning the brake linings. Cleaning the brake pads is advisable in wet weather, prior to long-term parking, and after the

Anti-lock braking system (ABS) The ABS system helps to improve vehicle con- trol (stopping and steering) during severe brak-ing conditions by limiting brake lockup.
When the system "senses" impending lockup, braking pressure is automatically modulated inorder to help prevent lockup that could lead to askid. The system performs a brief self-diagnostic test when the engine has been started and driverreleases the brake pedal. Another automatic testmay be performed when the vehicle first reachesa speed of approximately 6 mph (10 km/h). Thebrake pedal will pulsate several times and asound may be audible from the ABS controlmodule, which is normal.
