When the “-” shift paddle switch is operated in the D position
When the “-” shift paddle switch is operated in the D position, a shift range
will be automatically selected. The highest gear of the first shift range will
be one gear lower than the gear in use during normal D position driving.
Automatic deactivation of shift range selection in the D position
Shift range selection in the D position will be deactivated in the following
situations:
When the vehicle comes to a stop
When range 6 is selected and the accelerator pedal is depressed
If the accelerator pedal is depressed for more than a certain period of
time
To protect automatic transmission
A function is adopted that automatically selects a higher shift range when
the fluid temperature is high.
Gear range display when driving
The current gear is displayed on the multi-information display. (P. 184)
Downshifting restrictions warning buzzer
To help ensure safety and driving performance, downshifting operation may
sometimes be restricted. In some circumstances, downshifting may not be
possible even when the shift lever or shift paddle switch is operated. (The
warning buzzer will sound twice.)
When driving with the cruise control system or dynamic radar cruise control
system
Engine braking will not occur during shift range selection in the D position
or S mode, even when downshifting to range 5 or 4. (P. 198, 202)
Snow mode automatic deactivation
Snow mode is automatically deactivated if the “ENGINE START STOP”
switch is turned off after driving in snow mode.
If the shift lever cannot be shifted from P

If does not come on even after shifting the shift lever to S
This may indicate a malfunction in the automatic transmission system. Have
the vehicle inspected by any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional, immediately.
(In this situation, the vehicle will operate as if the shift lever is in D.)
AI-SHIFT
The AI-SHIFT automatically shifts the gear to the suitable position accord-
ing to the driver performance and driving conditions.
The AI-SHIFT automatically operates when the shift lever is in the D posi-
tion. However, operating the “-” paddle shift switch will restrict the func-
tion’s operation. (Shifting the shift lever to the S position cancels the
function.)
CAUTION
When driving on slippery road surfaces
Be careful of downshifting and sudden acceleration, as this could result in
the vehicle skidding to the side or spinning.

2-2. Instrument cluster
IS250/220d/200d_EEGear position display
(vehicles with an automatic transmission only)
Indicates the current gear, and the range of gears
that is available when the shift lever is in the D
or S position. The gear range is shown by the
number of dots () and the current gear is shown
as a number. The transmission automatically
selects the gears within the driver selected gear
range.
In the illustration to the left, a range of 6 available
gears (1 through 6) has been selected by the driver.
(The shift lever is in the D or S position with 6
ranges enabled.) It is possible for the transmission
to automatically select between all 6 of the gears.
In this case, the transmission has selected third
gear.
System check display
After switching the “ENGINE START STOP” switch to IGNITION ON
mode, “CHECK” is displayed while system operation is checked. When the
system check is complete, “COMPLETED” is displayed before returning to
the normal screen.
Outside temperature display
In the following situations, the correct outside temperature may not be dis-
played, or the display may take longer than normal to change.
When stopped, or driving at low speeds (less than 20 km/h [12 mph])
When the outside temperature has changed suddenly (at the entrance/exit
of a garage, tunnel, etc.)

IS250/220d/200d_EE
CAUTION
The ABS does not operate effectively when
The limits of tire gripping performance have been exceeded.
The vehicle hydroplanes while driving at high speed on the wet or slick
road.
Stopping distance when the ABS is operating may exceed that of normal
conditions
The ABS is not designed to shorten the vehicle's stopping distance. Always
maintain a safe distance from the vehicle in front of you in the following sit-
uations.
When driving on dirt, gravel or snow-covered roads
When driving with tire chains
When driving over bumps in the road
When driving over roads with potholes or roads with uneven surfaces
TRC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC system is operating.
Do not drive the vehicle in conditions where stability and power may be
lost.
Hill- start assist control does not operate effectively when (vehicles with an
automatic transmission)
Do not overly rely on the hill-start assist control. The hill start assist control
may not operate effectively on steep inclines and roads covered with ice.
When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving
may cause an accident, resulting in death or serious injury. Exercise particu-
lar care when the indicator light flashes.
When TRC and VSC are off
Be especially careful and drive at a speed appropriate to the road conditions.
As these are systems to help enhance vehicle stability and driving force, do
not turn off TRC and VSC unless necessary.

Selecting tire chains
Tire chains can be mounted on 16- and 17-inch tires. They cannot
be mounted on 18-inch tires. Use the correct tire chain size when
mounting the tire chains.
Chain size is regulated for each tire size.
Side chain
(3 mm [0.12 in.] in diameter)
Cross chain
(4 mm [0.16 in.] in diameter)
Regulations on the use of tire chains
Regulations regarding the use of tire chains vary according to
location and type of road. Always check local regulations before
installing chains.
Install the chains on the rear tires.
When driving the vehicle
Accelerate the vehicle slowly and drive at a reduced speed
suitable to road conditions.
When parking the vehicle
Park the vehicle and move the shift lever to P (automatic
transmission) or 1 or R (manual transmission) without setting
the parking brake. The parking brake may freeze up, prevent-
ing it from being released. If necessary, block the wheels to
prevent inadvertent sliding or creeping.
