turn the
Oband up for more
frequent wipes or down for less
frequent wipes. If Rainsense is
enabled, see “Rainsense”later in this
section.
If the windshield wipers are in use
while driving, the exterior lamps come
on automatically if the exterior lamp
control is in AUTO. The transition
time for the lamps coming on varies
based on wiper speed. See “Lights On

Fuel Gauge
Base Level
Uplevel
When the ignition is on, the fuel
gauge indicates about how much fuel
is left in the tank. There is an arrow near the fuel gauge
pointing to the side of the vehicle the
fuel door is on.
When the indicator nears empty, the
low fuel light comes on. There still is
a little fuel left, but the vehicle should
be refueled soon.
Here are three things that some
owners ask about. None of these show
a problem with the fuel gauge:
.It takes a little more, or less fuel to
fill up than the gauge indicated. For
example, the gauge may have
indicated the tank was half full, but
it actually took a little more, or less
than half the tank's capacity to fill
the tank.
.The gauge moves a little while
turning a corner, speeding up or
braking.
.The gauge takes a few seconds to
stabilize after the ignition is turned
on and goes back to empty when
the ignition is turned off.
