Check surroundings for safety.
If a bright light (for example, sunlight reflected off the vehicle
body) is picked up by the camera, the smear effect* peculiar to
the camera may occur.
*: Smear effect — A phenomenon that occurs when a bright
light (for example, sunlight reflected off the vehicle body) is
picked up by the camera; when transmitted by the camera, the
light source appears to have a vertical streak above and below
it.
CRUISE CONTROL
The cruise control is designed to maintain a set cruising
speed without requiring the driver to operate the
accelerator. Cruising speed can be set to any speed above
40 km/h (25 mph).
Within the limits of the engine’s capabilities, cruising speed can
be maintained up or down grades. However, changes in
vehicle speed may occur on steeper grades.
CAUTION
 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
snowcovered) or winding roads.
 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.

STARTING AND DRIVING
436To turn the system off, push the “ON
−OFF” button. Make sure
the “CRUISE” indicator light is off.
If the conventional cruise control mode automatically cancels
out other than for the above cases, have your vehicle checked
by your Lexus dealer at the earliest opportunity.
(d) Resuming the conventional cruise control mode
If the conventional cruise control mode is temporarily
cancelled, the cruising speed can be resumed by pushing the
lever up in the “+ RES” direction.
Vehicle speed must be above 40 km/h (25 mph).
(e) Resetting to a faster speed
Push the lever up in the “+ RES” direction and hold it. Release
the lever when the desired speed is attained. While the lever
is held up, the vehicle will gradually gain speed.
When the difference between the actual vehicle speed and the
set speed is less than 5 km/h (3 mph), the set speed can be
increased 1.6 km/h (1 mph) each time by pushing the lever up
in the “+ RES” direction quickly within 0.6 seconds.
However, a faster way to reset is to accelerate the vehicle and
then push the lever down in the “ − SET” direction. (f) Resetting to a slower speed
Push the lever down in the “
− SET” direction and hold it.
Release the lever when the desired speed is attained. While
the lever is held down, the vehicle speed will gradually
decrease.
When the difference between the actual vehicle speed and the
set speed is less than 5 km/h (3 mph), the set speed can be
lowered 1.6 km/h (1 mph) each time by pushing the lever down
in the “− SET” direction quickly within 0.6 seconds.
However, a faster way to reset is to accelerate the vehicle and
then push the lever down in the “ − SET” direction.
With automatic transmission (standard type) —
Even if you downshift from “D” to “4” in the conventional cruise
control mode, engine braking will not be enabled because this
mode is not cancelled. To decrease the vehicle’s speed, reset
to a slower speed with the cruise control lever or depress the
brake pedal. If you use the brake pedal, cruise control is
cancelled.
With automatic transmission (multi −mode type) —
Even if you downshift from “D” or “5” (fifth range) to “4” (fourth
range) in the conventional cruise control mode, engine braking
will not be enabled because this mode is not cancelled. To
decrease the vehicle’s speed, reset to a slower speed with the
cruise control lever or depress the brake pedal. If you use the
brake pedal, cruise control is cancelled.

CAUTION
Under certain slippery road conditions, full traction of
the vehicle and power against 4 wheels cannot be
maintained, even though the traction control system is
in operation. Do not drive the vehicle under any speed
or maneuvering conditions which may cause the
vehicle to lose traction control. In situations where the
road surface is covered with ice or snow, your vehicle
should be fitted with snow tires or tire chains. Always
drive at an appropriate and cautious speed for the
present road conditions.
