the front windshield washer. If the uid level is low in the
washer bottle, you may not be able to wash your rear
window. If you can wash your windshield, but not
your rear window, check the uid level.Cruise Control
Your vehicle may have this feature. With cruise control,
you can maintain a speed of about 25 mph (40 km/h)
or more without keeping your foot on the accelerator.
This can really help on long trips. Cruise control
does not work at speeds below about 25 mph (40 km/h).
When you apply your brakes, the cruise control shuts off.
{CAUTION:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do
not use your cruise control on winding roads
or in heavy traffic.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire
traction can cause needless wheel spinning,
and you could lose control. Do not use cruise
control on slippery roads.

weather or a tunnel. This is normal.
There is a delay in the transition between the daytime

Lamps (DRL) and the automatic headlamp systems so
that driving under bridges or bright overhead street
lights does not affect the system. The DRL and
automatic headlamp system will only be affected when
the light sensor sees a change in lighting lasting
longer than the delay.
To idle your vehicle with the automatic headlamp
system off, set the parking brake while the ignition is
off. Then start your vehicle. The automatic headlamp
system will stay off until you release the parking brake.You may be able to turn off your automatic headlamp
