WARNING!
Leaving the Speed Control ON when not in use is
dangerous. You could accidentally set the system or
cause it to go faster than you want. You could lose
control and have an accident. Always leave the
system OFF when you aren’t using it.
Driving Up or Down Hills
When going up or down hills, it is possible for your
vehicle to lose or gain speed, even though the Speed
Control is engaged. The automatic transmission may also
downshift to a lower gear, to maintain speed going up or
down hills. If going down a hill steep enough to cause the
vehicle to gain speed, press the brake pedal, which will
disengage the Speed Control and help slow your vehicle.
WARNING!
To help keep your vehicle under control, do not use
Speed Control under these conditions:
• When it is not possible to keep your vehicle at a set
speed.
• On slippery roads, such as on snow or ice.
• In heavy or varying traffic volume, in traffic that varies
in speed, or on winding roads.
• Be sure to turn the Speed Control switch to the OFF
position when not in use to avoid accidental engage-
ment.
