Driving
When driving at about 25 mph (40 km/h) or above: Take your foot off the
pedal and press down the RES/+/SET/– switch when you re ach the desired speed.
The moment you release the switch, the set speed is fixed, and ACC with Low Speed
Follow begins.
When you use ACC with Low Speed Follow, Stra ight Driving Assist (a feature of the
Electric Power Steering system) is activated.
By enabling the steering system to automa tically compensate for natural steering
pull, Straight Driving Assist makes it easier for you to keep your vehicle in a straight
line.
When driving slower than about 25 mph (40 km/h): If the vehicle is moving
and the brake pedal is not depressed, pres sing the switch fixes the set speed to
about 25 mph (40 km/h) regardless of current vehicle speed. If the vehicle is
stationary, you can set the vehicle speed even with the brake pedal depressed.
■To Set the Vehicle Speed1 Adaptive Cruise Control (ACC) with Low Speed Follow
Do not use ACC with Low Speed Follow under the
following conditions:
•On roads with frequent la ne-change or continuous
stop and go traffic, ACC with Low Speed Follow
cannot keep an appropriate distance between your
vehicle and the vehicle ahead of you.
•On roads with sharp turns.•On roads with steep downhill sections, as the set
vehicle speed can be exceeded by coasting. In such
cases, ACC with Low Speed Follow will not apply
the brakes to maintain the set speed.
•On roads with toll collection facilities or other
objects between lanes of traffic, or in parking
areas, or faci lities with driv e through access.

■There is no vehicle ahead
Your vehicle maintains the set speed without
having to keep your foot on the brake or

the set speed, ACC with Low Speed Follow
accelerates your vehicle to the set speed, and
then maintains it.

You can temporarily increase the vehicle speed . In this case, there is no audible or
visual alert even if a vehicle is in the ACC with Low Speed Follow range.
ACC with Low Speed Follow stays on unle ss you cancel it. Once you release the
accelerator pedal, the system resume s an appropriate speed for keeping the
following interval while a vehicle ahead is within the ACC with Low Speed Follow
range.

•A vehicle that cuts in front of you is going faster
than your vehicle, gradua lly increasing the interval
between the vehicles.
