This symbol also comes on when the mechanical parking brake is only slightly applied.
Airbags - SRS
If this light comes on while the vehicle is being driven, or remains on for longer than approximately 10 seconds after
the vehicle has been started, the SRS system's diagnostic functions have detected a fault in a seat belt lock or
pretensioner, a front airbag, side impact airbag, and/or an inflatable curtain. Have the system(s) inspected by a trained
and qualified Volvo service technician as soon as possible.
Seat belt reminder
This symbol comes on for approximately 6 seconds if the driver has not fastened his or her seat belt.
Generator not charging
This symbol comes on during driving if a fault has occurred in the electrical system. Contact an authorized Volvo
workshop.
Engine temperature
Engine overheating can result from low oil or coolant levels, towing or hard driving at high heat and altitude, or
mechanical malfunction. Engine overheating will be signaled with text and a red warning triangle in the middle of the
instrument display. The exact text will depend on the degree of overheating. It may range from " HIGH ENGINE
TEMP - SLOW DOWN " to "HIGH ENGINE TEMP - STOP ENGINE ." If appropriate, other messages, such as
" COOLANT LEVEL LOW " will also be displayed. If your engine does overheat so that you must stop the engine,
always allow the engine to cool before attempting to check oil and coolant levels.
Fault in brake system
If this symbol lights, the brake fluid level may be too low. Stop the vehicle in a safe place and check the level in the
brake fluid reservoir, see page 211
. If the level in the reservoir is below MIN , the vehicle should be transported to an
authorized Volvo workshop to have the brake system checked.
If the brake and ABS 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 driving.
If the symbols remain on, check the level in the brake fluid reservoir. See page 211. If the brake fluid level is
normal but the symbols are still lit, the vehicle can be driven, with great care, to an authorized Volvo workshop to
have the brake system checked.
If the level in the reservoir is below MIN , the vehicle should be transported to an authorized Volvo workshop to
have the brake system checked.
WARNING
If the fluid level is below the MIN mark in the reservoir or if a warning message is displayed in the text window:
DO NOT DRIVE. Have the vehicle towed to a trained and qualified Volvo service technician and have the brake
system inspected.
If the ABS and Brake system lights are on at the same time, there is a risk of reduced vehicle stability.

Instruments and controls

NOTE
Press the brake pedal hard and maintain pressure on the pedal - do not pump the brakes.
WARNING
If the fluid level is below the MIN mark in the reservoir or if a brake system message is shown in the information
display: DO NOT DRIVE. Have the vehicle towed to a trained and qualified Volvo service technician and have the
brake system inspected.
Power brakes function only when the engine is running
The power brakes utilize vacuum pressure which is only created when the engine is running. Never let the vehicle roll
to a stop with the engine switched off.
If the power brakes are not working, the brake pedal must be pressed approximately five times harder than usual to
make up for the lack of power assistance. This can happen for example when towing your vehicle or if the engine is
switched off when the vehicle is rolling. The brake pedal feels harder than usual.
Water on brake discs and brake pads affects braking
Driving in rain and slush or passing through an automatic car wash can cause water to collect on the brake discs and
pads. This will cause a delay in braking effect when the pedal is depressed. To avoid such a delay when the brakes are
needed, depress the pedal occasionally when driving through rain, slush, etc. This will remove the water from the
brakes. Check that brake application feels normal. This should also be done after washing or starting in very damp or
cold weather.
Severe strain on the brake system
The brakes will be subject to severe strain when driving in mountains or hilly areas, or when towing a trailer. Vehicle
speed is usually slower, which means that the cooling of the brakes is less efficient than when driving on level roads.
To reduce the strain on the brakes, shift into a lower gear and let the engine help with the braking. Do not forget that if
you are towing a trailer, the brakes will be subjected to a greater than normal load.
Anti-lock braking system
The Anti-lock Braking System (ABS) helps to improve vehicle control (stopping and steering) during severe braking
conditions by limiting brake lockup. When the system "senses" impending lockup, braking pressure is automatically
modulated in order to help prevent lockup that could lead to a skid.
The system performs a self -diagnostic test when the engine is started and when the vehicle first reaches a speed of
approximately 12 mph (20 km/h). The brake pedal will pulsate several times and a sound may be audible from the
ABS control module. This is normal.
114 03 Your driving environment
Brakes
Cleaning the brake discs
Coatings of dirt and water on the brake discs may result in delayed brake function. This delay is minimized by
cleaning the brake linings.
Cleaning the brake pads is advisable in wet weather, prior to long-term parking, and after the vehicle has been washed.
Do this by braking gently for a short period while the vehicle is moving.
Emergency Brake Assistance

EBA is designed to provide full brake effect immediately in the event of sudden, hard braking. The system is activated
by the speed with which the brake pedal is depressed.
When the EBA system is activated, the brake pedal will go down and pressure in the brake system immediately
increases to the maximum level. Maintain full pressure on the brake pedal in order to utilize the system completely.
EBA is automatically deactivated when the brake pedal is released.
NOTE
When the EBA system is activated, the brake pedal will go down and pressure in the brake system immediately
increases to the maximum level. You must maintain full pressure on the brake pedal in order to utilize the system
completely. There will be no braking effect if the pedal is released. EBA is automatically deactivated when the brake
pedal is released.
When the vehicle has been parked for some time, the brake pedal may sink more than usual when the engine is
started. This is normal and the pedal will return to its usual position when it is released.

Park assist (option)
Front park assist
The distance monitored in front of the vehicle is approximately 2.5 ft (0.8 m). The audible signal comes from the audio
system's front speakers.
It may not be possible to combine auxiliary headlights and front park assist since these lights could trigger the system's
sensors.
Faults in the system
If the information symbol illuminates and Park Assist syst Service required is shown on the information display, this
indicates that the system is not functioning properly and has been disengaged. Consult a trained and qualified Volvo
service technician.
CAUTION
In certain circumstances, the park assist system may give unexpected warning signals that can be caused by external
sound sources that use the same ultrasound frequencies as the system. This may include such things as the horns of
other vehicles, wet tires on asphalt, pneumatic brakes, motorcycle exhaust pipes, etc. This does not indicate a fault in
the system.
Cleaning the sensors
The sensors must be cleaned regularly to ensure that they work properly. Clean them with water and a suitable car
washing detergent.
Ice and snow covering the sensors may cause incorrect warning signals.

NOTE
If the sensors are obstructed by e.g., dirt, snow, or ice, this could result in false warning signals from the park assist
system.

Blind Spot Information System (option)
Introduction
BLIS camera
Indicator light
BLIS symbol
The Blind Spot Information System (BLIS) is an information system that indicates the presence of another vehicle
moving in the same direction as your vehicle in the sideview mirror's "blind area."
CAUTION
The BLIS system should only be repaired by a trained and qualified Volvo service technician.
WARNING
BLIS is an information system, NOT a warning or safety system.
BLIS does not eliminate the need for you to visually confirm the conditions around you, and the need for you to
turn your head and shoulders to make sure that you can safely change lanes.
As the driver, you have full responsibility for changing lanes in a safe manner.
The system is based on digital camera technology. The cameras are located beneath the side-view mirrors.
When one (or both) of the cameras have detected a vehicle in the blind area (up to approximately 10 ft. (3 meters)
from the side of your vehicle, and up to approximately 31 ft. (9.5 meters) behind the side-view mirror), see the
illustration, the indicator light in the door panel illuminates. The light will glow continuously to alert the driver of the
vehicle in the blind area.
NOTE

being towed behind a car or truck.
WARNING
BLIS does not react to cyclists or mopeds.
BLIS does not react to vehicles that are standing still.
The function of the BLIS cameras may be affected by intense light, or when driving at night in areas where there
are no external sources of light (e.g., street lights, other vehicles, etc.). In such cases, the system may react as if the
cameras were obscured.
In both of the above mentioned conditions, a message will appear in the information display.
When driving in such conditions, the system's function will be limited or it may be temporarily switched off. See
page 182
for instructions.
When the message is no longer displayed, BLIS will return to normal function.
The BLIS cameras have the same limitation as the human eye. In other words, their "vision is impaired" by
adverse weather conditions such as heavy snowfall, dense fog, etc.
181 04 Comfort and driving pleasure
Blind Spot Information System (option)
Limitations
In certain situations, the BLIS indicator light(s) may illuminate even when there are no other vehicles in the area
monitored by the system.
NOTE
If the BLIS indicator lights illuminate occasionally even when there are no other vehicles in the blind area, this does
not indicate a fault in the system. In the event of a fault, Blind spot syst. service required will be displayed.
The following are several examples of situations in which the BLIS indicator light(s) may illuminate even when there
are no other vehicles in the area monitored by the system.
Cleaning the BLIS camera lenses
In order to function optimally, the BLIS camera lenses must be kept clean. They can be wiped clean with a soft cloth
or wet sponge.
CAUTION
Clean the lenses carefully to avoid scratching.
The lenses are electrically heated to help melt ice or snow. If necessary, gently brush away snow from the lenses.

CAUTION
Engine damage will occur if water is drawn into the air cleaner.
If the vehicle is driven through water deeper than 9 in (25 cm), water may enter the differential and the
transmission. This reduces the oil's lubricating capacity and may shorten the service life of these components.
Do not allow the vehicle to stand in water up to the door sills longer than absolutely necessary. This could result
in electrical malfunctions.
If the engine has been stopped while the vehicle is in water, do not attempt to restart it. Have the vehicle towed
out of the water.
Engine and cooling system
Under special conditions, for example when driving in hilly terrain, extreme heat or with heavy loads, there is a risk
that the engine and cooling system will overheat. Proceed as follows to avoid overheating the engine.
Maintain a low speed when driving with a trailer up long, steep hills.
Do not turn the engine off immediately when stopping after a hard drive.
WARNING
The cooling fan may start or continue to operate (for up to 6 minutes) after the engine has been switched off.
Remove any auxiliary lights from in front of the grille when driving in hot weather conditions.
Do not exceed engine speeds of 4500 rpm if driving with a trailer in hilly terrain. The oil temperature could become
too high.
Conserving electrical current
Keep the following in mind to help minimize battery drain:
When the engine is not running, avoid using ignition mode II . Many electrical systems (the audio system, the
optional navigation system, power windows, etc) will function in ignition modes 0 and I . These modes reduce drain on
the battery.
Please keep in mind that using systems, accessories, etc., that consume a great deal of current when the engine is not
running could result in the battery being completely drained.
The optional 12 volt socket in the trunk provides electrical current even with the ignition switched off, which drains
the battery.
190 05 During your trip
Driving recommendations
Before a long distance trip
It is always worthwhile to have your vehicle checked by a trained and qualified Volvo service technician before
driving long distances. Your retailer will also be able to supply you with bulbs, fuses, spark plugs and wiper blades for
your use in the event that problems occur.
As a minimum, the following items should be checked before any long trip:
Check that engine runs smoothly and that fuel consumption is normal.
Check for fuel, oil, and fluid leakage
Have the transmission oil level checked.
Check condition of drive belts.
Check state of the battery's charge.
