Buick 2010 Lucerne Automobile User Manual


 
Clear ice and snow from the wiper blades before using
them. If frozen to the windshield, carefully loosen or
thaw them. Damaged blades should be replaced.
Heavy snow or ice can overload the wiper motor. A
circuit breaker will stop the motor until it cools.
The vehicle has wiper-activated headlamps. After the
windshield wipers have completed eight wipe cycles
within four minutes, the headlamps automatically
turn on. See Wiper Activated Headlamps on page 4-12
for more information.
Rainsense
II Wipers
If the vehicle has this feature, the moisture sensor is
mounted on the interior of the windshield beside
the rearview mirror and is used to automatically operate
the wipers. This system operates by monitoring the
amount of moisture build-up on the windshield. Wipes
occur as needed to clear the windshield depending
on the driving conditions and the sensitivity setting. In
light rain or snow, fewer wipes will occur. In heavy
rain or snow, wipes will occur more frequently.
The system operates in the delay mode. If the system is
left on for long periods of time, occasional wipes may
occur without any moisture on the windshield. This
is normal and indicates that the Rainsense
system
is active.
The Rainsense
system is activated by turning the
wiper control band to one of the five sensitivity levels
within the delay area. The position closest to off is
the lowest sensitivity setting, level one. This allows more
rain or snow to collect on the windshield between
wipes. Turning the wiper band away from you to higher
sensitivity levels increases the sensitivity of the
system and frequency of wipes. The highest sensitivity
setting, level five is closest to low. A single wipe will
occur each time you turn the wiper stalk to a higher
sensitivity level to indicate that the sensitivity level has
been increased.
Notice: Going through an automatic car wash with
the wipers on can damage them. Turn the wipers
off when going through an automatic car wash.
The MIST and wash cycle operates as normal and are
not affected by the Rainsense
function. The system
can be overridden at any time by manually changing the
wiper control to low or high speed.
Notice: Do not place stickers or other items on the
exterior glass surface directly in front of the rain
sensor.
