Cruise Control - Lexus RX300 Manual

STARTING AND DRIVING

CRUISE CONTROL

The cruise control allows you to cruise the vehicle at a desired
speed over 40 km/h (25 mph) with your foot off the accelerator
pedal.
Your cruising speed can be maintained although a slight speed
change may occur when driving up or down a gradient, within the
limits of engine performance. On steeper hills, a great speed change
will occur so it is better to drive without the cruise control.
When the cruise control is on, the driving pattern of the automatic
transmission is fixed in the normal position, regardless of the
position of the selector switch.
CAUTION
D To help maintain maximum control of your vehicle, do not
use the cruise control when driving in heavy or varying
traffic, or on slippery (rainy, icy or snow–covered) or
winding roads.
D Avoid vehicle speed increases when driving downhill. If the
vehicle speed is too fast in relation to the cruise control set
speed, cancel the cruise control then downshift the
transmission to use engine braking to slow down.

Turning on the system
31R012a
To operate the cruise control, push the main switch. This turns the
system on. The indicator light in the instrument cluster shows that
you can now set your desired cruising speed. Another push on the
switch will turn the system completely off.
When the ignition key is turned off, the main switch is also
automatically turned off. To use the cruise control again, push the
main switch again to turn it on.
CAUTION
To avoid accidental cruise control engagement, keep the main
switch off when not using the cruise control.
