Crash mode – general information
After a collision, the functionality of some of the vehicle's systems may be reduced as asafety precaution.
Warning symbol: analog instrument panel
Warning symbol: digital instrument panel* If the vehicle has been involved in a collision, the text
Safety mode See manual may
appear in the information display.
NOTE
This text can only be shown if the display is undamaged and the vehicle's electricalsystem is intact.
Crash mode is a feature that is triggered if one or more of the safety systems (e.g.front (p. 32) or side airbags (p. 39), an inflat-able curtain (p. 41), or one or more of the seatbelt pretensioners) has deployed. The colli-sion may have damaged an important func-tion in the vehicle, such as the fuel lines, sen-sors for one of the safety systems, the brakesystem, etc.
WARNING
• Never attempt to repair the vehicle yourself or to reset the electrical sys-tem after the vehicle has displayed
Safety mode See manual. This could
result in injury or improper system function.
• Restoring the vehicle to normal operat-ing status should only be done by atrained and qualified Volvo servicetechnician.
• After
Safety mode See manual has
been displayed, if you detect the odor of fuel vapor, or see any signs of fuelleakage, do not attempt to start thevehicle. Leave the vehicle immediately.

Malfunction Indicator LightAs you drive, a computer called On-Board Diagnostics II (OBDII) monitors your vehicle'sengine, transmission, electrical and emissionsystems. The malfunction indicator light will illuminate if the computer senses a condition that poten-tially may need correcting. When this hap-pens, please have your vehicle checked by atrained and qualified Volvo service technicianas soon as possible. A malfunction indicator light may have many causes. Sometimes, you may not notice achange in your car's behavior. Even so, anuncorrected condition could hurt fuel econ-omy, emission controls, and drivability.Extended driving without correcting the causecould even damage other components inyour vehicle. This light may illuminate if the fuel filler cap is not closed tightly or if the engine was runningwhile the vehicle was refueled.
Anti-lock Brake System (ABS)If the warning light comes on, there may be a malfunction in the ABS system (the standardbraking system will still function). Check thesystem by:
1. Stopping in a safe place and switching off
the ignition.
2. Restart the engine. 3. If the warning light goes off, no further
action is required.
If the indicator light remains on, the vehicle should be driven to a trained and qualifiedVolvo service technician for inspection, seeBrakes – general (p. 250) for additional infor-mation.
Rear fog lightsThis symbol indicates that the rear fog lights are on.
Stability systemThis indicator symbol flashes when the stabil- ity system is actively working to stabilize thevehicle, see Stability system – introduction(p. 162) for more detailed information.
Stability system - Sport modeThis symbol illuminates to indicate that the stability system's Sport mode has been acti-
vated to help provide maximum tractive force,for example when driving with snow chains,or driving in deep snow or loose sand.
Low fuel levelWhen this light comes on, the vehicle should be refueled as soon as possible. See Refuel-ing – fuel requirements (p. 261) for informa-tion about fuel and refueling.
Information symbolThe information symbol lights up and a text message is displayed to provide the driverwith necessary information about one of thevehicle's systems. The message can beerased and the symbol can be turned off by pressing the
OK button (see Information dis-
play – menu controls (p. 106) for information)or this will take place automatically after ashort time (the length of time varies, depend-ing on the function affected). The information symbol may also illuminate together with other symbols.
High beam indicatorThis symbol illuminates when the high beam headlights are on, or if the high beam flashfunction is used.
Left turn signal indicator
Right turn signal indicator
NOTE
• Both turn signal indicators will flash when the hazard warning flashers areused.
• If either of these indicators flash fasterthan normal, the direction indicatorsare not functioning properly.
Tire pressure monitoring system (TPMS)*
This symbol illuminates to indicate that tire pressure in one or more tires is low, see TirePressure Monitoring System (TPMS) – generalinformation (p. 291) for detailed information.
Eco* function onThe symbol will illuminate when the Eco func- tion is activated.

Generator not chargingThis symbol comes on during driving if a fault has occurred in the electrical system. Contactan authorized Volvo workshop.
Engine temperatureEngine overheating can result from low oil or coolant levels, towing or hard driving at highheat and altitude, or mechanical malfunction.Engine overheating will be signaled with textand a red warning triangle in the middle of theinstrument display. The exact text will dependon the degree of overheating. It may range from
High engine temp Reduce speed toHigh engine temp Stop engine. If appropri-
ate, other messages, such as Coolant level
low, Stop safely will also be displayed. If
your engine does overheat so that you must stop the engine, always allow the engine tocool before attempting to check oil and cool-ant levels. See Engine compartment – coolant (p. 316) for more information.
Fault in brake systemIf this symbol lights, the brake fluid level may be too low. Stop the vehicle in a safe placeand check the level in the brake fluid reser-voir, see Engine compartment – brake fluid(p. 317). If the level in the reservoir is belowMIN , the vehicle should be transported to an
authorized Volvo workshop to have the brakesystem checked. If the
and symbols come on
at the same time, there may be a fault in the brake force distribution system.
1. Stop the vehicle in a safe place and turn off the engine.
2. Restart the engine.
• If both symbols extinguish, continue driv- ing.
• If the symbols remain on, check the levelin the brake fluid reservoir, see Enginecompartment – brake fluid (p. 317). If thebrake fluid level is normal but the sym-bols are still lit, the vehicle can be driven,with great care, to an authorized Volvoworkshop to have the brake systemchecked.
• If the level in the reservoir is below
MIN,
the vehicle should be transported to anauthorized Volvo workshop to have thebrake system checked.WARNING
• If the fluid level is below the
MIN mark
in the reservoir or if a warning mes- sage is displayed in the text window:DO NOT DRIVE . Have the vehicle
towed to a trained and qualified Volvoservice technician and have the brakesystem inspected.
• If the
and symbols
are on at the same time, there is a risk of reduced vehicle stability.
Warning symbolThe red warning symbol lights up to indicate a problem related to safety and/or drivability.A message will also appear in the instrumentpanel. The symbol remains visible until thefault has been rectified but the text messagecan be cleared with the OK button, see Infor-
mation display – menu controls (p. 106). Thewarning symbol can also come on in conjunc-tion with other symbols. Action:
1. Stop in a safe place. Do not drive the vehicle further.
2. Read the information on the display. Implement the action in accordance with the message in the display. Clear themessage using OK.

Toggling between ACC and CC (standard Cruise Control)
Adaptive Cruise Control (ACC) helps the driver maintain a safe distance/time interval tothe vehicle ahead.
Switching from ACC to CCThis may be useful if, for example, the radarsensor is obstructed in some way. SeeAdaptive Cruise Control – limitations (p. 180)for additional information.
• Press and hold the
button; the symbol
in the instrument panel will switch from
to .
> This activates the standard cruise control function (see Cruise control (CC) – intro- duction (p. 168)).
WARNING
Switching from ACC to CC means that:
• Your vehicle will
no longer automati-
cally maintain a set distance to a vehi- cle ahead.
• Only the set speed will be maintainedand the driver will have to apply thebrakes when needed.
Switching from CC to ACC
Switch off cruise control by pressing once
or twice as needed according to the instruc- tions in the previous section "Turning ACC off completely." The next time the system isswitched on, ACC will be reactivated.

Cruise control (CC) – deactivating
Cruise control is designed to assist the driver by maintaining a set speed. It is primarilyintended for use on long straight roads insteady traffic, such as on highways and othermain roads.
Automatic deactivationThe cruise control is automatically deacti-vated
temporarily if one of the following
occurs: • If the speed drops below approximately 20 mph (30 km/h).
• When the brake pedal is depressed.
• If the gear selector is moved to positionN
.
• During wheel spin or wheel lock-up.
• If the vehicle's speed is increased byusing the accelerator pedal for more than1 minute.
• Engine speed (rpm) is too high or too low.
The currently set speed will be saved in the system's memory.
Temporary deactivationThe driver can temporarily deactivate thecruise control by pressing 0. The saved
speed is shown in brackets in the informationdisplay.

WARNING
• Adaptive Cruise Control is not a colli- sion avoidance system. The driver isalways responsible for applying thebrakes if the system does not detectanother vehicle.
• Adaptive Cruise Control does not reactto people or animals, or small vehiclessuch as bicycles and motorcycles. Italso does not react to slow moving,parked or approaching vehicles, orstationary objects.
• Do not use Adaptive Cruise Control indemanding driving conditions such ascity driving or other heavy traffic situa-tions, in slippery conditions, whenthere is a great deal of water or slushon the road, during heavy rain orsnow, in poor visibility, on windingroads or on highway on- or off-ramps.
The distance to the vehicle ahead (in the same lane) is monitored by a radar sensor.Your vehicle's speed is regulated by acceler-ating and braking. The brakes may emit asound when they are being modulated by theadaptive cruise control system. This is nor-mal.
WARNING
The brake pedal moves when the adaptive cruise control system modulates thebrakes. Do not rest your foot under thebrake pedal.
The ACC system is designed to smoothly regulate speed. However, the driver mustapply the brakes in situations that requireimmediate braking. This applies when thereare great differences in speed between vehi-cles, or if the vehicle ahead brakes suddenly.
WARNING
Due to limitations in the radar sensor, braking may occur unexpectedly or not atall, see Adaptive Cruise Control – limita-tions (p. 180).
Adaptive Cruise Control can be put in active mode at any permitted speed. However, if thevehicle's speed falls below 18 mph (30 km/h)or if engine speed (rpm) becomes too low,ACC disengages (goes into standby mode)and will no longer modulate the brakes. Thedriver will then have to maintain a safe dis-tance to the vehicle ahead.
WARNING
When Adaptive Cruise Control is in standby mode or is switched off com-pletely, the brakes will not be modulatedautomatically. The driver must assume fullcontrol over the vehicle.
Warning light—driver braking requiredAdaptive Cruise Control can exert brake force that is equivalent to approximately 40% ofthe vehicle's total braking capacity. In situa-tions requiring more brake force than ACCcan provide and if the driver does not applythe brakes, an audible signal from the Colli-sion Warning system will sound and warninglight will illuminate (see Collision warning* –function (p. 198)) in the windshield to alertthe driver to react.
NOTE
Strong sunlight, reflections, extreme light contrasts, the use of sunglasses, or if thedriver is not looking straight ahead maymake the visual warning signal in the wind-shield difficult to see.

WARNING
Adaptive Cruise Control only warns of vehicles detected by the radar sensor, seeAdaptive Cruise Control – limitations(p. 180). In some cases there may be nowarning or the warning may be delayed.The driver should always apply the brakeswhen necessary.
Steep inclines and/or heavy loadsACC is primarily intended for use on fairly level roads. The system may have difficultymaintaining the correct distance to a vehicleahead on steep inclines, if the vehicle is car-rying a heavy load or is towing a trailer. Inthese situations, the driver should always beprepared to apply the brakes if necessary.

WARNING
The vehicle may accelerate quickly after
has been pressed if its current speed is
considerably lower than the set speed.
Standby mode due to action by the driver
ACC is temporarily deactivated and put in standby mode:
• if the brakes are applied
• if the gear selector is moved to
N
• if the driver drives faster than the set speed for more than
1 minute.
In this happens, the driver will have to regu- late the vehicle's speed.
NOTE
If the accelerator pedal is only depressed for a short time, such as when passinganother vehicle, ACC is deactivated tem-porarily and is reactivated when the pedalis released.
Automatic standby modeACC is linked to other systems such as the stability system. If this system is not function-ing properly, ACC will switch off automati-cally. In the event of automatic deactivation, an audible signal will sound and the message
Cruise control Cancelled is shown in the
instrument panel. The driver must then inter- vene and adapt the vehicle's speed to thesurrounding traffic and regulate the distanceto the vehicle ahead. An automatic switch to standby mode may be caused if:
• engine speed (rpm) is too high/low
• The driver's door is opened
• The driver unbuckles his/her seat belt
• the vehicle's speed goes below 18 mph (30 km/h)
• the wheels lose traction
• brake temperature is high
• the radar sensor is obstructed by, forexample, wet snow or rain.
Resuming the set speedIf ACC is in standby mode, it can be reactiva- ted by pressing the
button on the steering
wheel keypad. The vehicle will return to the most recently set speed.
WARNING
The vehicle may accelerate quickly after
has been pressed if its current speed is
considerably lower than the set speed.
Turning ACC off completely
Controls and display
Resume previous settings.
Off/On/Standby mode
• From standby mode, press (2)
once.
• From active mode, press (2)
twice.
The set speed and time interval are then cleared from the system's memory and can- not be resumed by pressing (1)
.

The driver will then have to reactivate ACC in one of the following ways:
• By pressing
•By accelerating up to at least 3 mph (4 km/h). ACC will then resume followingthe vehicle ahead.
Your vehicle will then resume following the vehicle ahead at the set time interval.
NOTE
ACC can remain active and keep your vehicle at a standstill for up to 4 minutes.After 4 minutes have elapsed, the parkingbrake will be engaged and ACC will go intostandby mode. To reactivate ACC, the driver must release the parking brake (see Parking brake –general information (p. 254)).
Automatic standby mode when ACC changes target vehicles
If the vehicle ahead turns suddenly, there may be a stationary vehicle ahead The following only applies at speeds below approximately 18 mph (30 km/h)
:
If ACC changes target vehicles (the vehicle that the radar sensor has detected) from amoving vehicle to a stationary one, the sys-tem will apply the brakes in your vehicle.
WARNING
At speeds above 18 mph (30 km/h), ACC
will not react to a stationary vehicle and apply the brakes but will instead acceler-ate to the previously set speed. The drivermust actively apply the brakes to stop thevehicle.
ACC disengages and goes into standby mode if:
• Your vehicle's speed goes below 10 mph (15 km/h) and ACC cannot determine ifthe target object is a stationary vehicle orsome other type of object such as e.g., aspeed bump.
• Your vehicle's speed goes below 10 mph(15 km/h) and the vehicle ahead turns sothat ACC no longer has a target vehicle tofollow.
No automatic braking when at a standstill
In certain situations, ACC will no longer apply the brakes and go into standby mode whilethe vehicle is not moving. This means that thedriver will have to apply the brakes. This happens if:
• The driver presses the brake pedal
• The parking brake is activated
• The gear selected is moved to
P, N or R
• The driver presses the
button to put
ACC in standby mode
The parking brake is applied automatically
In certain situations, ACC will apply the park- ing brake in order to continue keeping thevehicle at a standstill. This happens if:
• The driver opens the door or takes off his/her seat belt
• The stability system is put in Sport mode(see Stability system – operation (p. 163))
• ACC has kept the vehicle at a standstillfor more than 2 minutes
• The engine has been switched off
• The brakes have overheated
