2-4. Using other driving systems
2

When driving
The system continues follow-up cruising while adjusting for changes in the
speed of the vehicle ahead in order to maintain the vehicle-to-vehicle dis-
tance set by the driver.
Example of acceleration (when there are no longer vehicles driving
slower than the set speed in the lane ahead): When the speed is set to
62 mph (100 km/h) and the vehicle ahead driving at 50 mph (80
km/h) is out of the lane
When the vehicle ahead of you executes a lane change, the system slowly
accelerates until the set vehicle speed is reached. The system then returns to
fixed speed cruising.
nDynamic radar cruise control warning lights, messages and buzzers
Warning lights, messages and buzzers are used to indicate a system malfunction or
to alert you to the need for caution while driving. (→P. 3 9 2 )
nThe dynamic radar cruise can be set when
lThe shift lever is in the D position or S position. However, it cannot be set if any
of the ranges 1 through 3 has been selected.
lVehicle speed is between approximately 30 mph (50 km/h) and 85 mph (135
km/h).
nAccelerating
The vehicle can be accelerated normally.
nAutomatically canceling vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the follow-
ing situations.
lVehicle speed falls below 25 mph (40 km/h)
lVSC is activated
lThe sensor cannot operate correctly because it is covered in some way.
lThe windshield wipers are operating at high speed.
lThe “ECT SNOW” switch is set to snow mode.
If vehicle-to-vehicle distance control driving is automatically canceled for any other
reason, there may be a malfunction in the system. Contact your Lexus dealer.

4-1. Maintenance and care
NOTICE
nTo protect your vehicle’s painted surfaces
Do not use organic cleaners such as benzene or gasoline.
nCleaning the exterior lights
lWash carefully. Do not use organic substances or scrub with a hard brush.
This may damage the surfaces of the lights.
lDo not apply wax on the surfaces of the lights.
Wax may cause damage to the lenses.
nTo prevent damage to the windshield wiper arms
When lifting the wiper arms away from the windshield, pull the driver side wiper
arm upward first, and repeat for the passenger side. When returning the wipers to
their original position, do so from the passenger side first.
nWhen using an automatic car wash (vehicles with the rain-sensing windshield
wipers only)
Set the wiper switch to the off position.
If the wiper switch is in “AUTO”, the wipers
may operate and the wiper blades may be
damaged.
