Volvo Structural Parts Statement
Volvo is one of the leading companies for carsafety.
Volvo engineers and manufactures vehiclesdesigned to help protect vehicle occupants in theevent of a collision.
Volvos are designed to absorb the impact of acollision. This energy absorption system including,but not limited to, structural components such asbumper reinforcement bars, bumper energyabsorbers, frames, rails, fender aprons, A-pillars,B-pillars and body panels must work together tomaintain cabin integrity and protect the vehicleoccupants.
The supplemental restraint system including butnot limited to air bags, side curtain air bags, anddeployment sensors work together with theabove components to provide proper timing forair bag deployment.
Due to the above, Volvo Car USA does not sup-port the use of aftermarket, alternative or any-thing other than original Volvo parts for collisionrepair.
Volvo Car USA also recommends using Volvo-approved replacement glass. The use of after-market glass, particularly a windshield, can havean adverse effect on collision avoidance andadvanced lighting systems.
In addition Volvo does not support the use or re-use of structural components from an existing
vehicle that has been previously damaged.Although these parts may appear equivalent, it isdifficult to tell if the parts have been previouslyreplaced with non-OE parts or if the part hasbeen damaged as a result of a prior collision. Thequality of these used parts may also have beenaffected due to environmental exposure.

Driver distraction
A driver has a responsibility to do everythingpossible to ensure his or her own safety and thesafety of passengers in the vehicle and otherssharing the roadway. Part of this responsibility isavoiding distractions, including performing activi-ties that are not directly related to controlling thevehicle in the driving environment.
Your new Volvo is, or can be, equipped with fea-ture-rich entertainment and communication sys-tems. These include hands-free cellular tele-phones, navigation systems, and multipurposeaudio systems. You may also own other portableelectronic devices for your own convenience.When used properly and safely, they enrich thedriving experience. Improperly used, any of thesecould cause a distraction.
For all of these systems, we want to provide thefollowing warning that reflects the strong Volvoconcern for your safety. Never use these devicesor any feature of your vehicle in a way that dis-tracts you from the task of driving safely. Distrac-tion can lead to a serious accident. In addition tothis general warning, we offer the following guid-ance regarding specific new features that may befound in your vehicle:

ECO Climate
In Pure mode, ECO climate is automatically acti-vated in the passenger compartment to helpreduce energy consumption.

NOTE
When the Pure drive mode is activated, set-tings for certain climate system and electricityconsuming functions are reduced. Some ofthese settings can be reset manually, but fullfunctionality will only be restored by leavingPure mode or adapting the Individual drivemode to full climate system functionality.
If condensation forms on the windows, tap themax defroster button, which will function normally.

AWD
Improves the vehicle's traction and handlingby increasing all-wheel drive.
This drive mode locks the vehicle in all-wheeldrive. An optimal distribution between front andrear axle torque helps provide the best possiblecontrol, stability and traction, e.g. on slipperyroads or when towing a heavy trailer or anothervehicle. The AWD drive mode is always availableregardless of the hybrid battery's charge status.
Both the combustion engine and the electricmotor are engaged to enable all-wheel drive,which results in higher fuel consumption.
In the other drive modes, the vehicle automati-cally adapts the need for all-wheel drive accord-ing to the road surface, and can activate the elec-tric motor or start the combustion engine as nee-ded.
POWER
Power mode is designed to provide sportierdriving characteristics and a faster accelera-tion response.
This drive mode maximizes the combined powerfrom the combustion engine and the electricmotor by providing power to both the front andrear wheels. Gear shifting will be faster and moredistinct and the transmission will prioritize gearswith a higher traction force. Steering response isfaster and suspension is stiffer.
Both the combustion engine and the electricmotor are engaged to enable all-wheel drive,which results in higher fuel consumption.
This drive mode is optimized for maximum per-formance and throttle response. It changes thethrottle response, gear shifting program andturbo boost system. Chassis settings and steer-ing and brake response are also optimized. ThePower drive mode is always available regardlessof the hybrid battery's charge status.

INDIVIDUAL
Customizes drive mode to personal preferen-ces.
Select one of the drive modes as a basis andadjust the settings to achieve your preferred driv-ing characteristics. These settings will be storedin your driver profile.
