NOTICE
■Precautions for opening/closing the retractable hardtop
●Before operating the retractable hardtop, make sure that the areas 2.3 ft. (70
cm) above the roof and 1.2 ft. (35 cm) behind the rear bumper is clear of obstruc-
tions.
●Do not put any items or packages on the package tray even if they are extremely
small.
●Do not store luggage on or allow anyone to sit on the retractable hardtop.
●When the outside temperature is -4°F (-20°C) or below or if the side windows
are frozen shut, do not open or close the retractable hardtop.
●Do not open the retractable hardtop if it is wet. Possible interior water damage,
water stains or mildew may result.
●When opening or closing the retractable hardtop, turn the rear window defog-
gers off.
●Do not leave the vehicle for an extended period of time with an open or close
operation incomplete.
●Do not open the trunk lid while the retractable hardtop is operating.
●If the retractable hardtop is operated repeatedly within a short period of time, the
motor protection circuit may activate, caus ing the roof switch to be disabled. In
this case, turn the “ENGINE START STOP” switch to ACCESSORY mode or off
and, after waiting for a while, perform the procedure again.
●Do not place anything on or under the luggage cover.
●The luggage cover should be attached securely. Protruding luggage may inter-
fere with the proper operat ion of the retractable hardtop, causing it to become
damaged.
■To prevent battery discharge
Do not operate the retractable hardtop repeatedly when the engine is off.

When driving
CAUTION
■When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and reduce
your ability to control the vehicle, resulting in an accident.
●Sudden changes in engine speed, such as engine braking caused by up-shifting
or down-shifting, may cause the vehicl e to skid, resulting in an accident.
●After driving through a puddle, lightly depress the brake pedal to make sure that
the brakes are functioning properly. Wet brake pads may prevent the brakes from
functioning properly. If the brakes on on ly one side are wet and not functioning
properly, steering control may be af fected, resulting in an accident.
■When shifting the shift lever
With automatic transmission vehicles, be ca reful not to shift the shift lever with the
accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may cause an
accident and result in death or serious injury.
■If you hear a squealing or scraping no ise (brake pad wear limit indicators)
Have your Lexus dealer check and replac e 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
those of the brake discs are exceeded.
■When the vehicle is stopped
●Do not race the engine.
If the vehicle is in any gear other than P (vehicles with an automatic transmission
only) or N the vehicle may accelerate suddenly and unexpectedly, and may cause
an accident.
●Do not leave the vehicle with the engine running for a long time.
If such a situation cannot be avoided, park the vehicle in an open space and
check that exhaust fumes do no t enter the vehicle interior.
●With automatic transmission vehicles, in order to prevent accidents due to the
vehicle rolling away, always keep depressing the brake pedal while the engine is
running, and apply the parking brake as necessary.

2-1. Driving procedures
CAUTION
■When 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.
■Stopping 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. Turning the engine off while driving will not cause loss of steering or
braking control, but the power assist to thes e systems will be lost. This will make it
more difficult to steer and brake, so you should pull over and stop the vehicle as
soon as it is safe to do so.
NOTICE
■To prevent battery discharge
Do not leave the “ENGINE START STOP” switch in ACCESSORY or IGNITION
ON mode for long periods without the engine running.
■When starting the engine
●Do not race a cold engine.
●If the engine becomes difficult to start or stalls frequently, have the engine
checked immediately.

■Shifting the shift lever
While the “ENGINE START STOP” switch is in IGNITION
ON mode, depress the brake pedal and move the shift lever.
■ Shift position uses
*1: Shifting to the D position allows the sy stem to select a gear suitable for the
driving conditions. Setting the shift le ver to the D position is recommended
for normal driving.
*2: Selecting shift ranges using S mode re stricts the upper limit of the possible
gear ranges, controls engine brakin g forces, and prevents unnecessary
upshifting.
