YOUR VOLVO
* Option/accessory.
28 goal. In addition to continuous environmental refinement of conventional gasoline-poweredinternal combustion engines, Volvo is activelylooking at advanced technology alternative-fuelvehicles. When you drive a Volvo, you become our partner in the work to lessen the vehicle's impact on theenvironment. To reduce your vehicle's environ-mental impact, you can:
• Maintain proper air pressure in your tires.Tests have shown decreased fuel economywith improperly inflated tires.
• Follow the recommended maintenanceschedule in your Warranty and ServiceRecords Information booklet.
• Drive at a constant speed whenever possible.
• See a trained and qualified Volvo servicetechnician as soon as possible for inspectionif the check engine (malfunction indicator)light illuminates, or stays on after the vehiclehas started.
• Properly dispose of any vehicle-related wastesuch as used motor oil, used batteries, brakepads, etc.
• When cleaning your vehicle, please use gen-uine Volvo car care products. All Volvo carcare products are formulated to be environ-mentally friendly.

IntelliSafe - driver support
IntelliSafe is Volvo Cars' philosophy regarding vehicle safety. IntelliSafe consists of a number ofsystems, both standard and optional, that aredesigned to help make driving safer, preventaccidents and protect passengers and otherroad users.
SupportIntelliSafe includes driver support functions such as Adaptive cruise control * which helps the driver
to maintain an even speed combined with a pre- selected time interval to the vehicle ahead. Pilot Assist 4
helps the driver keep the vehicle in
the current traffic lane by providing steering assistance and maintaining an even speed and aset time interval to the vehicle ahead. Park Assist Pilot * helps the driver pull into and
out of parking spaces. Other examples of systems that can help the driver are the Active main beam, Cross Traffic Alert (CTA) * and Blind Spot Information (BLIS) *
systems.
PreventionCity Safety is a function intended to help prevent accidents. The function can help prevent or miti-gate a collision with pedestrians, cyclists, largeanimals or other vehicles. Light, sound and pulsa-tions in the brake pedal are provided to alert of a
4 Depending on market, this function can be either standard or optional.

SAFETY

Starting and moving the vehiclewhen it is in safety mode If safety mode has been set, it may be possible to reset the system in order to start and movethe vehicle a short distance, for example, if it isblocking traffic.
Starting the vehicle when it is in safety mode
1. Check the vehicle for damage, particularly forfuel leakage. Make sure you do not detect any gasoline fumes. If the damage to the vehicle is minor and there is no fuel leakage/fumes, you mayattempt to start the engine.
WARNING
Never attempt to restart the vehicle if you smell fuel fumes when the message Safety
mode See Owner's manual is displayed in
the instrument panel. Leave the vehicle imme- diately.
2. Switch off the ignition. 3. Then try to start the vehicle.
> The vehicle's electrical system will per-form a system check and then attempt to reset to normal operating mode.
CAUTION
If the message Safety mode See Owner's
manual is still displayed, the vehicle should
not be driven or towed behind another vehi- cle. If the vehicle needs to be moved, it mustbe towed on a tow truck. Even if no damageis apparent, there may be hidden damage thatcould make the vehicle impossible to control.
Moving the vehicle when it is in safety mode
1. If the message Normal mode The vehicle
is now in normal mode is displayed after
attempting to start the engine, the vehicle may be moved carefully from its presentposition if, for example, it is blocking traffic.
2. Do not move the vehicle farther than abso- lutely necessary.
WARNING
When the vehicle is in safety mode, it should not be towed behind another vehicle. It shouldbe towed from the site on a tow truck. Volvorecommends towing the vehicle directly to anauthorized Volvo workshop.

Some examples of symbols and messages are shown in the table below.
SymbolMessageMeaning
Steady glow for approx. 2 seconds. System check when the engine is started.
Flashing light. The ESC is actively operating.
Steady glow. Sport mode is activated.
Note: The ESC system is not deactivated in this mode, but has partially reduced functionality.
ESC Temporarily offThe ESC system's functionality has been temporarily reduced due to high brake system temperatures. The function will be automatically reactivated when the brakes have cooled. See the message in the instrument panel.
ESC Service requiredThe ESC system is not functioning properly.
• Stop the vehicle in a safe place, turn off the engine and then restart it.
• Consult a workshop if the message persists
‒ an authorized Volvo workshop is recommended.

Brakes The brake pedal is used to apply the vehicle's regular brakes, which are part of the brake sys-tem.
The vehicle is equipped with two brake circuits. If one brake circuit is damaged, the brake pedal willgo down further when depressed. More pressurewill then be required from the driver for normalbraking effect. The driver's pressure on the brake pedal is enhanced by a power braking function.
WARNING
Power braking only functions if the engine is running.
If the brake pedal is used when the engine is turned off, the pedal will feel stiffer than usualand greater pressure must be applied to brakethe vehicle. In very hilly areas or when driving with a heavy load, manual gear shifting can be used to aug-ment the brakes with engine braking. Enginebraking is most effective if the same gear is usedboth uphill and downhill.
Anti-lock brakesThe vehicle is equipped with an Anti-lock BrakingSystem (ABS), which can help prevent thewheels from locking and help maintain steeringcontrol when braking. Vibrations may be felt from the brake pedal when ABS is operating, which isnormal. After the vehicle is started, a brief test of the ABS system is automatically performed when thedriver releases the brake pedal. An additionalautomatic test of the system may be performedwhen the vehicle is traveling at a low speed. Dur-ing the test, the brake pedal may feel as though itis pulsating.

Braking assist after a collision In a collision in which the activation level is reached for the pyrotechnic seat belt tensionersor airbags, or if a collision with a large animal isdetected, the vehicle's brakes will be automati-cally activated. This function is intended to helpprevent or reduce the effects of any subsequentcollision.
After a serious collision, it may no longer be pos- sible to control and steer the vehicle. In order toavoid or mitigate a possible further collision witha vehicle or an object in the vehicle's path, thebrake assist system is activated automatically tohelp stop the vehicle safely. The brake lights and hazard warning flashers are activated during braking. When the vehicle has stopped, the hazard warning flashers will con-tinue to flash and the parking brake will beapplied. If braking is not appropriate, e.g. if there is a risk of being hit by passing traffic, the driver can over-ride the system by depressing the acceleratorpedal. This function assumes that the brake system is intact after a collision. Brake assist is part of the Rear Collision Warning and Blind Spot Information safety systems.

Transmission The transmission is part of the vehicle's driveline (power transmission) between the engine andthe drive wheels. The function of the transmis-sion is to change gears depending on speedand power needs.
The vehicle has an 8-speed automatic transmis- sion. The number of gears allows the engine'storque and power band to be effectively utilized.Two of the gears are overdrive gears that savefuel when driving at a constant engine speed.Manual shifting is also possible. The instrumentpanel shows the gear currently in use.
CAUTION
Check the operating temperature of the transmission to help avoid damage to any ofthe drive system components. If there is a riskof overheating, a warning symbol will appearin the instrument panel and a text messagewill be displayed. Follow the recommenda-tions given.
Symbols in the instrument panelIf a problem should occur with the transmission, a symbol and a message will appear in the instru-ment panel.
