When driving
IS F_EE
Driving in the rain
Drive carefully when it is raining, because visibility will be reduced, the
windows may become fogged-up, and the road will be slippery.
Drive carefully when it starts to rain, because the road surface will be
especially slippery.
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 sur-
face, preventing the steering and brakes from operating properly.
Engine speed while driving
In the following conditions, the engine speed may become high while driv-
ing. This is due to automatic up-shifting control or down-shifting implemen-
tation to meet driving conditions. It does not indicate sudden acceleration.
The vehicle is judged to be driving uphill or downhill
When the accelerator pedal is released
Breaking in your new Lexus
To extend the life of the vehicle, the following precautions are recom-
mended to observe:
For the first 300 km (186 miles):
Avoid sudden stops.
For the first 1000 km (621 miles):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in the low gears.
• Do not drive at a constant speed for extended periods.
Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of
brake system needs bedding-down of the brake shoes periodically or when-
ever the parking brake shoes and/or drum are replaced. Have any authorized
Lexus dealer or repairer, or another duly qualified and equipped profes-
sional, perform the bedding down.
Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the avail-
ability of the correct fuel. (P. 4 7 4 )

2-1. Driving procedures

When starting off
To prevent the vehicle from creeping forward, keep the brake pedal firmly
depressed when shifting the shift lever.
When driving the vehicle
Do not drive if you are unfamiliar with the location of the brake and accel-
erator pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake
pedal will result in sudden acceleration that may lead to an accident
that could result in death or serious injury.
• When backing up, you may twist your body around, leading to a diffi-
culty in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the
vehicle only slightly, allowing you to depress the brake and accelerator
pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake
pedal using your left foot may delay response in an emergency, result-
ing in an accident.
Do not drive the vehicle over or stop the vehicle near flammable materi-
als.
Do not let the vehicle roll backwards while the shift lever is in a driving
position, or roll forward while the shift lever is in R.
Doing so may cause the engine to stall or lead to poor brake and steering
performance, resulting in an accident or damage to the vehicle.
If the smell of exhaust is noticed inside the vehicle, open the windows and
check that the trunk is closed. Large amounts of exhaust in the vehicle can
cause driver drowsiness and an accident, resulting in death or a serious
health hazard. Have the vehicle inspected by any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional, immedi-
ately.
Do not shift the shift lever to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle
control.
Do not shift the shift lever to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
Do not shift the shift lever to D while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle
control.

CAUTION
When starting the engine
Always start the engine while sitting in the driver's seat. Do not press the
accelerator 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 sec-
onds.
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 these 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.

sometimes be restricted. In some circumstances, downshifting may not be
possible even when the shift lever or paddle shift switch is operated. (A
buzzer will sound twice.)
When driving with the cruise control or dynamic radar cruise control
Engine braking will not occur during shift range selection in the D position,
even when downshifting to range 7, 6, 5 or 4. (P. 180, 184)

Automatic gear selection when the vehicle is stopped
When the vehicle comes to a stop, the transmission will automatically
downshift to allow you to start off in 1st gear.
When the vehicle is idling at high rpm in order to warm up, and the vehi-
cle is on a slippery road, the transmission will automatically shift to 2nd
gear for stopping and starting off.
When the shift lever is in D (paddle
shift switches operated) or in M, an
indicator on the tachometer illuminates
in 3 steps in the case of high engine
speeds to encourage the driver to
