▼Shift-up/Shift-down Request Display (Manual Transaxle)
The shift-up or shift-down reque
st display in the active driving display may be indicated
while the MRCC is operating. Whe n this occurs, shift gears because the gear position is not
appropriate.
Request Display
Shift up
Shift down
NOTE
If the gears are not shifted up even though the shift-up request indication is displayed, load
will be applied to the engine and the MRCC system may be automatically canceled or
engine damage could occur.
▼ Cruise Control Function
While this function is operating, the
headway control operation is canceled and
only the cruise control function operates.
The vehicle speed can be set more than
about 25 km/h (16 mph).
Use the cruise c
ontrol function on
expressways and other highways which do
not require a lot of repeated acceleration
and deceleration.
WA R N I N G
Do not use the cruise control function in
the following locations:
Otherwise, it could lead to an accident.
 Roads with sharp curves and where
vehicle
traffic is heavy and there is
insufficient space between vehicles.
(Driving under these conditions using the
cruise control function is not possible)
 Steep down slopes (Set speed may be
exceeded because
sufficient engine
braking cannot be applied)
 Slippery roads such as ice or snow-bound
roads ( Tires could spin causing you to
lose vehicle control)
Always drive carefully:
The warnings and brake control will not
operate after the headway control function
is canceled and the system is switched to
only the cruise control function. Depress
the brake pedal to decelerate according to
the surrounding conditions while keeping a
safer distance from the vehicle ahead and
always driving carefully.

system becomes operational when all of the following conditions are met.
The engine is running.
The vehicle speed is about 60 km/h (37 mph) or faster.
The system detects white (yellow) lane lines.
(If the system only detects a wh ite (yellow) line on either the left or right the system only
operates for a departure in the direction being detected.)
The driving lane is neither narrow nor wide.

The LAS&LDWS goes on stand-by status in the following cases:
The system cannot detect white (yellow) lane lines.
The vehicle speed is less than about 60 km/h (37 mph).
The ABS/TCS/DSC is operating.
The DSC is turned off.
(If the DSC is turned off while the system is operational, a warning beep is heard and the
system goes on standby.)
The vehicle is making a sharp curve.
The steering wheel is operated abruptly.
The brake pedal is depressed.

system becomes operational when a ll of the following conditions are met.
The system detects white (yellow) lane lines on both the right and left sides, or on either
side.
The vehicle speed is about 60 km/h (37 mph) or faster.
The vehicle is driven on a straig ht road or road with gentle curves.
The engine is running.
The LAS&LDWS goes on stand-by status in the following cases:
The system cannot detect white (yellow) lane lines.
The vehicle speed is less than about 60 km/h (37 mph).
The vehicle is making a sharp curve.
The vehicle is making a curve at an inappropriate speed.
NOTE
The LAS&LDWS remains on stand-by until it de tects white (yellow) lines on both the left
and right sides, or on either side.
When the system detects a white (yellow) lane line on one side only, the system will not
activate warnings for the lane line on the side that is not being detected.
The distance and warning sensitivity (likelihood of a warning) which the system uses to
determine the possibility of a lane departure can be changed.
