Volvo and the environment
Volvo is committed to the well-being of its cus-tomers. As a natural part of this commitment, wecare about the environment in which we all live.Concern for the environment means an everydayinvolvement in reducing our environmentalimpact.
Volvo's environmental activities are based on aholistic view, which means we consider the over-all environmental impact of a product throughoutits complete life cycle. In this context, design, pro-duction, product use, and recycling are all impor-tant considerations. In production, Volvo haspartly or completely phased out several chemicalsincluding CFCs, lead chromates, asbestos, andcadmium; and reduced the number of chemicalsused in our plants 50% since 1991.
Volvo was the first in the world to introduce intoproduction a three-way catalytic converter with aLambda sond, now called the heated oxygen sen-sor, in 1976. The current version of this highlyefficient system reduces emissions of harmfulsubstances (CO, HC, NOx) from the exhaust pipeby approximately 95 – 99% and the search toeliminate the remaining emissions continues.Volvo is the only automobile manufacturer tooffer CFC-free retrofit kits for the air conditioningsystem of all models as far back as the 1975model 240. Advanced electronic engine controlsand cleaner fuels are bringing us closer to ourgoal. 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 partnerin the work to lessen the car'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.

•If preconditioning is not possible in coldweather, use the seat and steering wheelheating primarily. Avoid heating the entirepassenger compartment, which reduces thehybrid battery's charge level.
•Choose the Pure drive mode to help mini-mize electric power consumption.
•In hilly terrain, put the gear selector in modeB to utilize the electric motor's braking func-tion when the accelerator pedal is released.This helps charge the hybrid battery.

This function is active at speeds from approx.90 mph (150 km/h) down to 3 mph (5 km/h).When braking at speeds outside of this range orduring harder braking, the hydraulic brake systemis used.

Cleaning the brake discs
Coatings of dirt and water on the brake discsmay result in delayed brake function. This delay isminimized by cleaning the brake linings.
Cleaning the brake pads is advisable in wetweather, prior to long-term parking, and after thevehicle has been washed. Do this by braking gen-tly for a short period while the vehicle is moving.
Driving on wet or salted roads
Prolonged driving on wet or salted roads canaffect brake function and increase stopping dis-tance. Be sure to keep a safe distance to thevehicle ahead when driving under these condi-tions.

Brake pad inspection
On vehicles equipped with a jack*, the conditionof the brake pads can be checked by raising thevehicle and performing a visual inspection of thebrake pads.

WARNING
•If the vehicle has been driven immediatelyprior to a brake pad inspection, the wheelhub, brake components, etc., will be veryhot. Allow time for these components tocool before carrying out the inspection.
•Apply the parking brake and put the gearselector in the Park (P) position.
•Block the wheels standing on the ground,use rigid wooden blocks or large stones.
WARNING
•Use the jack intended for the vehiclewhen changing a tire. For any other job,use stands to support the vehicle.
•The jack should be kept well-greased andclean, and should not be damaged.
•Be sure the jack is on a firm, level, non-slippery surface.
•No objects should be placed between thebase of jack and the ground, or betweenthe jack and the attachment bar on thevehicle.
•The jack must correctly engage the jackattachment.
•Never allow any part of your body to beextended under a vehicle supported by ajack.
