In addition to continuous environmental refinement of conventional gasoline-powered  internal combustion engines,
Volvo is actively looking at advanced technology  alternative-fuel vehicles.
When you drive a  Volvo, you become our partner in the work to lessen  the vehicle's impact on the environment.
To reduce your vehicle's environmental impact, you can:
 Maintain proper air pressure in your tires. Tests have shown decreased  fuel economy with improperly  inflated tires.
 Follow the recommended maintenance schedule in your Warranty and  Service Records Information booklet.
 Drive at a  constant speed.
 See  an  authorized Volvo retailer as soon as possible for inspection if the check engine (malfunction indicator) lamp
illuminates,  or stays on after the vehicle has started.
 Properly  dispose of any  vehicle-related waste such as used motor oil, used batteries, brake pads, etc.
 When cleaning your vehicle, use Volvo's  own vehicle care products,  all of which  have systematically been adapted
to the environment.

Important warnings
Accessory Installation
 We strongly recommend that Volvo owners install  only genuine, Volvo-approved accessories, and  that accessory
installations be  performed only by the factory-trained technicians at your authorized Volvo retailer.
 Genuine Volvo accessories are tested to ensure compatibility with the performance, safety, and  emission systems in
your vehicle. Additionally, your authorized Volvo retailer knows where  accessories may and  may not be  safely
installed in your Volvo. In all cases, please consult your authorized Volvo retailer before installing any  accessory  in or
on your vehicle.
 Accessories that have not been approved by Volvo may or may not be  specifically tested for compatibility with your
vehicle. Additionally, an  inexperienced installer may not be  familiar with some of your vehicle's systems.
 Any of your vehicle's performance and  safety systems could be  adversely affected if you install  accessories that
Volvo has not tested, or if you allow accessories to be  installed by someone unfamiliar with your vehicle.
 Damage caused by unapproved or improperly  installed accessories may not be  covered by your new vehicle
warranty. See  your Warranty and  Service Records Information booklet for more warranty information. Volvo assumes
no responsibility  for death, injury, or expenses that may result from  the installation  of non-genuine accessories.
Driver Distraction
 Driver distraction results from  driver activities that are not directly related to controlling the vehicle in the driving
environment. Your new Volvo is, or can be,  equipped with many feature-rich entertainment and  communication
systems. These include  hands-free cellular telephones, navigation systems, and  multipurpose audio systems. You may
also own other portable electronic  devices for your own convenience. When used properly and  safely, they enrich the
driving experience. Improperly used, any  of these could cause a  distraction.
 For all of these systems, we want  to provide the following warning that reflects  the strong Volvo concern for your
safety:
 Never  use these devices or any  feature of your vehicle in a  way that distracts you from  the task of driving safely.
Distraction  can lead to a  serious accident.In addition to this  general  warning, we offer  the following guidance
regarding specific newer  features that may be  found in your vehicle:
 Never  use a  hand -held cellular telephone while driving. Some jurisdictions  prohibit cellular telephone use by a
driver while the vehicle is moving.
 If your vehicle is equipped with a  navigation system, set and  make changes to your travel itinerary only with the
vehicle parked.
 Never  program your audio system while the vehicle is moving. Program  radio presets with the vehicle parked, and
ProCarManuals.com 

use your programmed presets to make radio use quicker and  simpler.
 Never  use portable computers or personal digital assistants while the vehicle is moving.
A driver has a  responsibility  to do everything possible to ensure his or her own safety and  the safety of passengers in
the vehicle and  others  sharing  the roadway.  Avoiding distractions is part of that responsibility.

radio in your vehicle is equipped to take advantage of this  system.
