Better Understanding Your Remote • More About Tires – Rolling Resistance Coefficient (RRC)
 Using your remote keyless entry system transmitter to lock and unlock the doors of your Subaru vehicle enhances convenience. However, just as interference can prevent the signal from your TV/cable remote control from reaching the TV/cable box, interference can block signals from your keyless transmitter to your vehicle.  When
unlocking the doors, please note: It is possible to press the unlock button too
quickly or not quickly enough. If the interval between the first and second press
of the unlock button (for unlocking all passenger doors and rear gate) is extremely
short, the system may not respond. All doors but the driver’s door will remain
locked. Although the second button press should be within five seconds of the first,
wait until the vehicle’s lights have flashed twice before pressing the button
again.Please refer to your owner’s manual for more information. BACK TO TOP  In addition to the tire ratings discussed in the fall 2004 issue of Drive, a rating typically not listed on the tire sidewall is the Rolling Resistance Coefficient (RRC). Factors influencing RRC are tire construction techniques and tread compounds. When comparing RRC values, a lower RRC indicates less resistance to movement. Rolling resistance is one of four factors that counter movement of a vehicle. The other three are overcoming inertia, driveline friction and aerodynamic drag. The effects of rolling resistance, particularly at highway speeds, is measurable in terms of reduced fuel economy. Thanks to Robert Shafer of Los Alamos, New Mexico, for referring us to this tire rating, which is likely to become increasingly important in the future.
