When driving
NOTICE
nIf you hear a squealing or scraping noise (brake pad wear limit indicators)
Have your Lexus dealer check and replace the brake pads as soon as possible.
The rotor damage can result if the pads are not replaced when needed.
Front brake only: Moderate levels of the brake pad and disc wear allow enhanced
front braking power. As a result, the discs may wear more quickly than conventional
brake discs. Therefore, when replacing the brake pads, Lexus recommends that you
also have the thickness of the discs measured.
It is dangerous to drive the vehicle when the wear limits of the brake pads and/or
that of the brake discs are exceeded.
nIf you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering wheel
firmly and gradually press the brake pedal to slow down the vehicle.
lIt may be difficult to control your vehicle.
lThe vehicle will make abnormal sounds.
lThe vehicle will behave abnormally.
Replace a flat tire with a new one. (→P. 4 0 6 )
nWhen 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.
lEngine stalling
lShort in electrical components
lEngine 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.
lBrake function
lChanges in quantity and quality of oil and fluid used for the engine, transmission,
transfer (AWD vehicles), differential, etc.
lLubricant condition for the propeller shaft (AWD vehicles), bearings and suspen-
sion joints (where possible) and the function of all joints, bearings, etc.

2-1. Driving procedures
CAUTION
nWhen starting the engine
Always start the engine while sitting in the driver’s seat. Do not press the accelera-
tor while starting the engine under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
nStopping the engine in an emergency
If you want to stop the engine in an emergency while driving the vehicle, push and
hold the “ENGINE START STOP” switch for more than 3 seconds.
However, do not touch the “ENGINE START STOP” switch while driving except in
an emergency. If the engine stops while the vehicle is being driven, this could lead to
an unexpected accident.
NOTICE
nTo prevent battery discharge
Do not leave the “ENGINE START STOP” switch in ACCESSORY or IGNITION
ON mode for long periods without the engine running.

2-1. Driving procedures
Selecting shift ranges in the D position
To drive using temporary shift range selection, operate the “-” shift paddle
switch. The shift range can then be selected by operating the “-” and “+”
shift paddle switches. Changing the shift range allows restriction of the
upper limit of the gears to be used, preventing unnecessary upshifting
and enabling the level of engine braking force to be selected.
Higher shift range
Lower shift range
The selected shift range, from 1 to
6, will be displayed in the meter
cluster.
To return to normal D position
driving, the “+” shift paddle switch
must be held down for a period of
time.
nSelecting a driving mode
The following patterns can be selected to suit current driving and
operating conditions.
Power mode
For powerful acceleration
and driving in mountainous
regions.
Normal mode
Snow mode
For accelerating and driving
on slippery road surfaces,
such as on snow.
Press “SNOW” to return to nor-
mal mode.

When driving
nShift ranges and their functions
A lower shift range will provide greater engine braking forces than a higher shift
range.
Shift rangeFunction
6Automatically selecting gears between 1 and 6
according to vehicle speed and driving conditions.
5Automatically selecting gears between 1 and 5
according to vehicle speed and driving conditions.
4Automatically selecting gears between 1 and 4
according to vehicle speed and driving conditions.
3Automatically selecting gears between 1 and 3
according to vehicle speed and driving conditions.

2-1. Driving procedures
Changing shift ranges in S mode
To enter S mode, shift the shift lever to the S position. The shift range can
then be selected by operating the “-” and “+” shift paddle switches or the
shift lever. Changing the shift range allows restriction of the upper limit of
the gears to be used, preventing unnecessary upshifting and enabling the
level of engine braking force to be selected.
Higher shift range
Lower shift range
The selected shift range, from 1 to
6, will be displayed in the meter
cluster.
The initial shift range in S mode is automatically set to 5 or 4 according to
vehicle speed. However, the initial shift range may be set to 3 or 2 if the
AI-SHIFT has operated while the shift lever was in the D position.
