Toyota Prius Owners Manual
The cruise control allows you to cruisethe vehicle at a desired speed over 40km/h (25 mph) even with your foot offthe accelerator pedal.
Your cruising speed can be maintained upor down grades within the limits of hybridsystem performance, although a slightspeed change may occur when driving upor down the grades. On steeper hills, agreater speed change will occur so it isbetter to drive without the cruise control.
To help maintain maximum controlof your vehicle, do not use thecruise control when driving inheavy or varying traffic, or on slippery(rainy, icy or snow–covered) orwinding roads.
Avoid vehicle speed increases whendriving downhill. If the vehiclespeed is too fast in relation to thecruise control set speed, cancel thecruise control then shift the shiftlever to “B” position to use enginebraking to slow down.
TURNING THE SYSTEM ON
To operate the cruise control, push the“ON·OFF” switch. This turns the systemon. The indicator light in the instrumentpanel shows that you can now set thevehicle at a desired cruising speed. Anotherpush on the switch will turn the systemcompletely off.
To avoid accidental cruise control engagement,keep the “ON·OFF” switchoff when not using the cruise control.
SETTING AT A DESIRED SPEED
The transaxle must be in “D” before youset the cruise control speed.
Bring your vehicle to the desired speed,push the lever down in the “– SET” directionand release it. This sets the vehicleat that speed.
If the speed is not satisfactory, tap thelever up for a faster speed, or tap it downfor a slower speed. Each tap changes theset speed by 1.6 km/h (1.0 mph). You cannow take your foot off the acceleratorpedal.
If you need acceleration—for example,when passing—depress the acceleratorpedal enough for the vehicle to exceedthe set speed. When you release it, thevehicle will return to the speed set priorto the acceleration.
CANCELING THE PRESET SPEED
You can cancel the preset speed by:
a. Pulling the control lever in the“CANCEL” direction and releasing it.
b. Depressing the brake pedal.
If the vehicle speed falls below about 40km/h (25 mph), the preset speed will automaticallycancel out.
If the vehicle speed drops 16 km/h (10mph) below the preset speed, the presetspeed will also automatically cancel out.
If the preset speed automatically cancelsout other than for the above cases, haveyour vehicle checked by your Toyota dealerat the earliest opportunity.
RESETTING TO A FASTER SPEED
Push the lever up in the “+ RES” directionand hold it. Release the lever when thedesired speed is attained. While the leveris held up, the vehicle will gradually gainspeed.
However, a faster way to reset is to acceleratethe vehicle and then push thecontrol lever down in the “– SET” direction.
RESETTING TO A SLOWER SPEED
Push the lever down in the “– SET” directionand hold it. Release the lever whenthe desired speed is attained. While thelever is held down, the vehicle speed willgradually decrease.
However, a faster way to reset is to depressthe brake pedal and then push thecontrol lever down in the “– SET” direction.
RESUMING THE PRESET SPEED
If the preset speed is cancelled by pullingthe control lever or by depressing thebrake pedal, pushing the lever up in the“+ RES” direction will restore the speedset prior to cancellation.
However, once the vehicle speed falls belowabout 40 km/h (25 mph), the presetspeed will not be resumed.
