NOTE
If the turn signal is used, neither of the driving lane assistance systems (LDW or LKA) willprovide an alert or steering assistance.
WARNING
This feature is only intended to assist the driver and does not function in all driving,weather, traffic or road conditions. As the driver, you have full responsibility for operating the vehicle in a safe manner.
Steering assistance (LKA only)In order for LKA's steering assistance to function, the driver's hands must be on the steering wheel,which the system monitors continuously.
If this is not the case, this sym-bol will illuminate in the instru- ment panel and
Lane Keeping
Aid Apply steering will appear
to alert the driver to actively steer the vehicle.
If the driver does not take action, an audible sig- nal will sound and LKA will go into standby mode.The function will not become available again untilthe driver actively steers the vehicle.
Dynamic cornering
The traffic lane assistance systems do not intervene in sharp curves
In certain cases, such as during active driving or if the turn signal is used, neither of the traffic lanesystems will react if the vehicle crosses a lanemarker line.
LimitationsIn certain demanding driving situations, the driv-ing lane assistance functions may not be able toassist the driver. In these situations, it may beadvisable to turn the function off. Examples of these situations: • road construction
• poor road surfaces
• edges or lines other than the lane's marker lines
• a very active driving style •
winter driving conditions
• bad weather with reduced visibility
The driving lane assistance function use the vehi- cle's camera, which has general limitations. Seethe article "Camera limitations."

Driving lane assistance symbols and messages
A number of symbols and messages relating to Lane Keeping Aid (LKA) and Lane DepartureWarning (LDW) may appear in the instrumentpanel.
Symbols in the instrument panelThe driving lane assistance systems use a symbol in theinstrument panel in differentsituations.
Several examples of the symbol's appearance will be given here:
Available
When the driving lane assistance systems are available,
the marker lines in the symbol will be white
LDW/LKA are monitoring the driving lane's marker line(s).
Not available
When the driving lane assistance systems are not avail-
able, the marker lines in the symbol will be gray
This is because LDW/LKA cannot monitor (detect) the driving lane's marker line(s) or thevehicle's speed is too low or the road is too nar-row.
Steering/warning indicator
Steering/warning: the side marker lines in the symbol will be colored
LDW/LKA alerts the driver that the vehicle is leaving its lane. LKA attempts to steer the vehicleback into the lane. LKA also indicates if the sys-tem is attempting to steer the vehicle back intoits lane.

STARTING AND DRIVING

Starting and driving
The vehicle is equipped with an automatic trans- mission that also makes it possible to shift gearsmanually. Certain functions can also be used when the engine is not running, depending on the ignitionmode being used.
Related information
• Starting the engine (p. 372)
• Ignition modes (p. 370)
• Automatic transmission (p. 395)
• Opening/closing the fuel filler door (p. 363)
• Parking brake (p. 352)
Brakes The brake system is a hydraulic system consist- ing of two separate brake circuits. If a problemshould occur in one of these circuits, it is stillpossible to stop the vehicle with the other brakecircuit.
Brake systemIf one of the brake circuits is not functioning, more pressure will be needed on the brake pedal(and the pedal will go down farther) for normalbraking effect. If the brake pedal must be depressed farther than normal and requires greater foot pressure,the stopping distance will be longer. Pressure on the brake pedal is enhanced by the power braking function.
WARNING
If vehicle does not have electrical current and both the electric motor and gasoline engineare switched off, the brakes cannot be usedto stop the vehicle.
When the Hill Start Assist function is being used, it will take slightly longer for the brake pedal toreturn to its normal position if the vehicle isparked on an incline or uneven surface. When driving in very hilly areas or if the vehicle is carrying a heavy load, using brake mode B to augment the brakes or the
Off Road* drive mode can also be used to increase the engine braking effect at low speeds.
Anti-lock Braking System
ABS
The ABS system helps to improve vehicle control (stopping and steering) during severe brakingconditions by limiting brake lockup. When ABS is operating, there may be some vibration in the brake pedal, which is normal. 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.
Function check when the engine is
started
A Plug-in Hybrid is equipped with a "brake bywire" brake system. A function check is per-formed each time the engine is started and thedriver depresses the brake pedal to move the gear selector from P.
In certain cases, a message may appear in the instrument panel saying that pressure on thebrake pedal is too low. Press harder on the pedal.
Light braking charges the hybrid batteryWhen the brakes are applied lightly, the electricmotor's braking function is used, which converts

kinetic energy into electricity that is used to charge the hybrid battery. This is indicated in theinstrument panel, see also the article "Generalinformation about the XC90 T8 Twin EnginePlug-in Hybrid".
Battery charging gauge in the instrument panel
This function is active at speeds from approx. 90 mph (150 km/h) down to 3 mph (5 km/h).When braking at speeds outside of this range orduring harder braking, the hydraulic brake systemis used.
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 thevehicle has been washed. Do this by braking gen-tly for a short period while the vehicle is moving.
Driving on wet or salted roadsProlonged driving on wet or salted roads canaffect brake function and increase stopping dis-tance. Be sure to keep a safe distance to thevehicle ahead when driving under these condi-tions.
Brake pad inspection
On vehicles equipped with a jack
*, the condition
of the brake pads can be checked by raising thevehicle and performing a visual inspection of thebrake 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.

WARNING
If both symbols illuminate at the same time and the brake level is below the MIN mark in
the reservoir or if a brake system-related mes-sage is shown in the instrument panel: DO
NOT DRIVE . Have the vehicle towed to a
trained and qualified Volvo service technician and have the brake system inspected. If both symbols illuminate at the same time and the brake level is normal (not below the
MIN mark in the reservoir) or if a brake sys-
tem-related message is shown in the instru- ment panel: drive the vehicle carefully to anauthorized Volvo workshop and have thebrake system inspected by a trained andqualified Volvo service technician.

Brake functions
The vehicle's standard braking features are aug- mented by a number of auxiliary help functions.
In addition to the wheel brakes and the parking brake, the vehicle is equipped with several auto-matic brake assist functions. These systems helpthe driver by e.g., keeping the vehicle stationarywhen the brake pedal is not depressed (at a traf-fic light or intersection), when starting up a hill orwhen driving down a hill. These systems include: • Auto-hold brakes
• Hill Start Assist
• Braking assist after a collision
• Hill Descent Control
