■When starting off on an uphill
The hill-start assist control will activate. (→P. 2 8 5 )
■Driving in the rain
●Drive carefully when it is raining, becaus e visibility will be reduced, the windows may
become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, beca use the road surface will be especially slip-
pery.
●Refrain from high speeds when driving on an expressway in the rain, because there may
be a layer of water between the tires and the road surface, preventing the steering and
brakes from operating properly.
■Engine speed while driving
In the following conditions, the engine speed may become high while driving. This is due
to automatic up-shifting control or down-shi fting implementation to meet driving condi-
tions. It does not indicate sudden acceleration.
●The vehicle is judged to be driving uphill or downhill
●When the accelerator pedal is released
●When the brake pedal is depressed while sport mode is selected
■Restraining the engine output (Brake Override System)
●When the accelerator and brake pedals are depressed at the same time, the engine
output may be restrained.
●A warning message is displayed on the mult i-information display while the system is
operating. If a warning message is shown on the multi-information display, read the
message and follow the instructions.

■Downshifting restriction warning buzzer
To help ensure safety and driving performance, downshifting operation may sometimes
be restricted. In some circumstances, downsh ifting may not be possible even when the
shift lever or paddle shift switch is operated. (A buzzer will sound twice.)
■Snow mode automatic deactivation
Snow mode is automatically deactivated if the engine switch is turned off after driving in
snow mode.
■Gear position display on the multi-information display
When Gear positions is selected for a Drive Information screen on the multi-information
display and the shift lever is in the D or M position, the currently selected gear position
will be displayed on the multi-information di splay. (The display changes according to the
shift lever position and driving conditions.)
■When driving with cruise control or dynamic radar cruise control activated
Even when performing the following actions with the intent of enabling engine braking,
engine braking will not activate because cruise control or dynamic radar cruise control
will not be canceled.
●While driving in the D position, downshifting to 7, 6, 5 or 4. ( →P. 24 0, 244)
●When switching th e driving mode to sport mode while driving in D position. ( →P. 2 8 3 )
■If the shift lever cannot be shifted from P
→P. 5 4 9
■AI-SHIFT
●The AI-SHIFT automatically selects the suitable gear according to driver performance
and driving conditions.
The AI-SHIFT automatically operates when the sh ift lever is in D. (Shifting the shift lever
to the M position cancels the function.)
●The G AI-SHIFT is automatically changed to a suitable gear step while running in sport
mode according to the driving operations and running conditions.
The G AI-SHIFT automatically operates when the drive mode select switch is set to
sport mode with the shift lever in the D posi tion. (The function will be canceled, if the
drive mode is select switch is set to normal mode or shift lever is put in the M position.)
CAUTION
■When driving on slippery road surfaces
Be careful of downshifting and sudden acceler ation, as this could result in the vehicle
skidding to the side or spinning.
■Gear Shift Indicator display (if equipped)
For safety, the driver should not look only at the display. Refer to the display when it is
safe to do so while considering actual traffic and road conditions.
Failure to do so may lead to an accident.

This mode employs a radar sensor to detect the presence of vehicles up to
approximately 120 m (400 ft.) ahead, determines the current vehicle-to-vehicle
following distance, and operates to maintain a suitable following distance from
the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when traveling on long downhill
slopes.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-vehicle dis-
tance can also be set by operating the vehicle-to-vehicle distance control.
Example of deceleration cruising
When the vehicle ahead is driving slower than the set speed
When a vehicle is detected running ahead of you, the system automatically deceler-
ates your vehicle. When a greater reduction in vehicle speed is necessary, the system
applies the brakes. A warning tone warns you when the system cannot decelerate suf-
ficiently to prevent your vehicle from closing in on the vehicle ahead.
Example of follow-up cruising
When following a vehicle driving slower than the set speed
The system continues follow-up cruising wh ile adjusting for changes in the speed of
the vehicle ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Example of acceleration
When there are no longer any vehicles ahead driving slower than the set
speed
The system accelerates until the set speed is reached. The system then returns to con-
stant speed cruising.
