LOW VOLTAGE
This message displays when the electrical system
is charging less than 10 volts or if the battery
has been drained. If this message displays
immediately after starting, it is possible that the
generator can still recharge the battery. The
battery should recharge while driving, but may
take a few hours to do so. Consider using
an auxiliary charger to boost the battery after
returning home or to a final destination. Make sure
you follow the manufacturer's instructions. If this
message displays while driving or after starting
your vehicle and stays on, have it checked
immediately by your dealer to determine the cause
of this problem. To help the generator recharge
the battery quickly, you can reduce the load on the
electrical system by turning off the accessories.
You can monitor battery voltage on the DIC
by pressing the INFO button. The normal range is
11.5 to 15.5 volts.
LOW WASHER FLUID
This message displays when the windshield
washer fluid is low. Fill the windshield washer fluid
reservoir as soon as possible. See Engine
Compartment Overview on page 374 for the
location of the windshield washer fluid reservoir.
Also, see Windshield Washer Fluid on page 397
for more information.
MAX (Maximum) SPEED XX MPH
(XX KM/H)
This message displays when a failure in the
magnetic ride control system has occurred. The
Powertrain Control Module (PCM) determines
the speed to which your vehicle is limited. Have
your vehicle serviced by your dealer if this
message appears.
