will be slippery.
●Drive carefully when it starts to rain,
because the road surface will be espe-
cially slippery.
●Refrain from high speeds when driving on
an expressway in the rain, because there
may be a layer of wa ter between the tires
and the road surface, preventing the
steering and brakes from operating
properly.

is due to automatic up-shifting control or
down-shifting implementation to meet driv-
ing conditions. It does not indicate sudden
acceleration.
●The vehicle is judged to be driving uphill
or downhill
●When the accelerator pedal is released
●When the brake pedal is firmly or quickly
depressed
■Restraining the engine output (Brake
Override System)
●When the accelerator and brake pedals
are depressed at the same time, the
engine output may be restrained.
●A warning message is displayed on the

tem is operating. If a warning message is
shown on the multi-information display,
read the message and follow the instruc-
tions.
■Restraining sudden start (Drive-Start

●For the first 621 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low gears.
• Do not drive at a constant speed for extended periods.
■Drum-in-disc type parking brake sys-
tem
Your vehicle has a drum-in-disc type park-
ing brake system. This type of brake system
needs bedding-down of the brake shoes
periodically or whenever the parking brake
shoes and/or drum are replaced. Have
your Lexus dealer perform the bedding
down operation.
■Operating your vehicle in a foreign
country
Comply with the relevant vehicle registra-
tion laws and confirm the availability of the
correct fuel. ( P.351)
WARNING
Observe the following precautions.
Failure to do so may result in death or
serious injury.
■When starting the vehicle
Always keep your foot on the brake
pedal while stopped with the engine run-
ning. This prevents the vehicle from
creeping.

1384-1. Before driving
WARNING
■When driving the vehicle
●Do not drive if you are unfamiliar with
the location of the brake and accelera-
tor pedals to avoid depressing the
wrong pedal.
• Accidentally depressing the accelera- tor pedal instead of the brake pedal
will result in sudden acceleration that
may lead to an accident.
• When backing up, you may twist your body around, leading to a difficulty 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. This allows 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, resulting in
an accident.
●Do not drive the vehicle over or stop
the vehicle near flammable materials.
The exhaust system and exhaust gases
can be extremely hot. These hot parts
may cause a fire if there is any flamma-
ble material nearby.
●During normal driving, do not turn off
the engine. Turning the engine off
while driving will not cause loss of
steering or braking control, however,
power assist to the steering will be lost.
This will make it more difficult to steer
smoothly, so you should pull over and
stop the vehicle as soon as it is safe to
do so.
In the event of an emergency, such as
if it becomes impo ssible to stop the
vehicle in the normal way: P.306
●Use engine braking (downshift) to
maintain a safe speed when driving
down a steep hill.
Using the brakes continuously may
cause the brakes to overheat and lose
effectiveness. ( P.150)
●Do not adjust the positions of the
steering wheel, the seat, or the inside
or outside rear view mirrors while driv-
ing.
Doing so may result in a loss of vehicle
control.
●Always check that all passengers’
arms, heads or other parts of their
body are not outside the vehicle.
●Do not drive in excess of the speed
limit. Even if the legal speed limit per-
mits it, do not drive over 85 mph (140
km/h) unless your vehicle has high-
speed capability tires. Driving over 85
mph (140 km/h) may result in tire fail-
ure, loss of control and possible injury.
Be sure to consult a tire dealer to
determine whether the tires on your
vehicle are high-speed capability tires
or not before driving at such speeds.
■When driving on slippery road sur-
faces
●Sudden braking, acceleration and
steering may cause tire slippage and
reduce your ability to control the vehi-
cle.
●Sudden acceleration, engine braking
due to shifting, or changes in engine
speed could cause the vehicle to skid,
resulting in an accident.
●After driving through a puddle, lightly
depress the brake pedal to make sure
that the brakes are functioning prop-
erly. Wet brake pads may prevent the
brakes from functioning properly. If
the brakes on only one side are wet
and not functioning properly, steering
control may be affected.
■When shifting the shift position
●Do not let the vehicle roll backward
while a forward driving position is
selected, or roll forw ard while the shift
position 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.
