Operation of each component
RC350/RCF_U (OM24636U)
When either “L” or “R” of the mirror select switch is selected, the outside rear
view mirrors will automatically angle downwards when the vehicle is reversing in
order to give a better view of the ground.
To disable this function, select neither “L” nor “R”.
■Adjusting the mirror angle when the vehicle is reversing
With the shift lever in R, adjust the mirror angle at a desired position.
The adjusted angle will be memorized and the mirror will automatically tilt to
the memorized angle whenever the shift lever is shifted to R from next time.
The memorized downward tilt position of the mirror is linked to the normal position
(angle adjusted with the shif t lever in other than R). Therefore, if the normal posi-
tion is changed after adjustment, th e tilt position will also change.
When the normal position is chang ed, readjust the angle in reversing.
■Mirror angle can be adjusted when
The engine switch is in ACCESSORY or IGNITION ON mode.
■When the mirrors are fogged up
The outside rear view mirrors can be cleare d using the mirror defoggers. Turn on the
rear window defogger to turn on the outside rear view mirror defoggers. ( P. 4 2 0 )
■Automatic adjustment of the mirror angle (if equipped)
A desired mirror face angle can be entered to memory and recalled automatically by the
driving position memory. ( P. 1 5 7 )
■Auto anti-glare function (if equipped)
When the anti-glare inside rear view mirror is set to automatic mode, the outside rear
view mirrors will activate in conjunction with the anti-glare inside rear view mirror to
reduce reflected light. ( P. 166)
Linked mirror function when reversing (if equipped)

■Important points while driving
Observe the following precautions while driving.
Failure to do so may result in loss of control of the vehicle and cause an accident, result-
ing in death or serious injury.
●Do not adjust the mirrors while driving.
●Do not drive with the mirrors folded.
●Both the driver and passenger side mirror s must be extended and properly adjusted
before driving.
■When the mirror defoggers are operating
Do not touch the rear view mirror surfaces, as they can become very hot and burn you.

NOTICE
■When driving the vehicle
●Do not depress the accelerator and brake pe dals at the same time while driving, as
this may restrain the engine output.
●Do not use the accelerator pedal or depress the accelerator and brake pedals at the
same time to hold the vehicle on a hill.
■When parking the vehicle
Always shift the shift lever to P. Failure to do so may cause the vehicle to move or the
vehicle may accelerate suddenly if the accelerator pedal is ac cidentally depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for an
extended period of time.
Doing so may damage the power steering motor.
●When driving over bumps in the road, drive as slowly as possible to avoid damaging
the wheels, underside of the vehicle, etc.
■If you get a flat tire while driving
A flat or damaged tire may cause the follo wing situations. Hold the steering wheel
firmly and gradually depress the brak e pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.
Information on what to do in case of a flat tire ( P. 5 6 0 , 5 74 )
■When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may cause the
following serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be sure to have
your Lexus dealer check the following:
●Brake function
●Changes in quantity and quality of oil and fluid used for the engine, transmission,
transfer (AWD models), differential, etc.
●Lubricant condition for the propeller shaft, bearings and suspension joints (where
possible), and the function of all joints, bearings, etc.

1964-2. Driving procedures
RC350/RCF_U (OM24636U)
■Auto power off function
If the vehicle is left in ACCESSORY mode for more than 20 minutes or IGNITION ON
mode (the engine is not running) for more than an hour with the shift lever in P, the engine
switch will automatically turn off. However, this function cannot entirely prevent battery
discharge. Do not leave the vehicle with the engine switch in ACCESSORY or IGNI-
TION ON mode for long periods of ti me when the engine is not running.
■Electronic key battery depletion

■Conditions affe cting operation
 P. 1 4 8
■Notes for the entry function
P. 1 4 9
■If the engine does not start
●Check that the shift lever is securely set in P. The engine may not start if the shift lever is
displaced out of P.
●The engine immobilizer system may not have been deactivated. ( P. 76 )
Contact your Lexus dealer.
■Steering lock
After turning the engine switch off and opening and closing the doors, the steering wheel
will be locked due to the stee ring lock function. Operating the engine switch again auto-
matically cancels the steering lock.
■When the steering lock cannot be released
■Steering lock motor overheating prevention
To prevent the steering lock motor from over heating, operation of the motor may be sus-
pended if the engine is turned on and off repeat edly in a short period of time. In this case,
refrain from operating the engine switch. After about 10 seconds, the steering lock
motor will resume functioning.
■When “Check Access System with Elec. Key” is displayed on the multi-information dis-
play
The system may be malfunctioning. Have the vehicle inspected by your Lexus dealer
immediately.
■If the electronic key battery is depleted
 P. 5 0 7
“Steering Lock active” will be displayed on the
multi-information display.
Check that the shift lever is in P. Press the
engine switch while turning the steering wheel
left and right.

■Conditions under which the vehicle-to-vehic le distance control mode may not func-
tion correctly
Operate the brake pedal (or accelerator pe dal operation depending on the situation)
as necessary in the following conditions as the radar sensor may not be able to cor-
rectly detect vehicles ahead, which may lead to an accident resulting in death or seri-
ous injury.
●When the road curves or when the lanes are
narrow
●When steering wheel operation or your posi-
tion in the lane is unstable
●When the vehicle ahead of you decelerates
suddenly
Accelerate Accelerate Decelerate

2524-5. Using the driving support systems
RC350/RCF_U (OM24636U)
●When sunlight or the headlights of oncoming vehicles are shining directly into the cam-
era lens
●When driving on roads that are branching or merging
●When driving on a road surface that is wet du e to rain, previous rainfall, standing water,
etc.
●When the vehicle experiences strong up-and -down motion such as when driving on an
extremely rough road or on a seam in the pavement
●When headlight brightness at nighttime is reduced due to dirt on the lenses, or when
the headlights are misaligned
●When driving on winding roads or roads that are uneven
●When driving on rough or unpaved roads
■When changing the tires
Depending on the tires used, sufficient performance may not be maintainable.
■Warning messages for the LDA system
Warning messages are used to indicate a syst em malfunction or to inform the driver of
the need for caution while driving. ( P. 545)
WA R N I N G
■Before using the LDA system
Do not rely solely on the LDA system. The LDA system does not drive the vehicle auto-
matically, nor does it reduce the amount of care you need to take. As such, the driver
must always assume full responsibility for understanding his/her surroundings, for
operating the steering wheel to correct the driving line, and for driving safely.
Inappropriate or negligent drivin g could lead to an accident.
■To avoid operating the LDA by mistake
Switch the LDA system off using the LDA switch when not in use.
■Situations unsuitable for LDA system
Do not use the LDA system in any of the following situations.
Otherwise, the system may not function correctly and could result in an accident.
●When driving with tire chains, a spare tire, or similar equipment
●When there are objects or structures along the roadside that might be misinterpreted
as lane markers (such as guardrails, a curb, reflector posts, etc.)
●When driving on snowy roads
●When pavement lane markers are difficult to see due to rain, snow, fog, sand, dirt, etc.
●When there are visible lines on the pavement from road repairs, or if the remains of
old lane markers are still visible on the road
●When driving on a road with lane closures due to maintenance, or when driving in a
temporary lane
