may be a layer of wa ter between the tires
and the road surface, preventing the
steering and brakes from operating prop-
erly.
■Engine speed while driving
In the following conditions, the engine
speed may become high while driving. This
is due to automatic up-shifting control or
down-shifting implementation to meet driv-
ing conditions. It does not indicate sudden

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.
■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 emer gency, resulting in
an accident.

WARNING
●Do not leave cigarette lighters in the
vehicle. If a cigarette lighter is in a
place such as the glove box or on the
floor, it may be lit accidentally when
luggage is loaded or the seat is
adjusted, causing a fire.
●Do not attach adhesive discs to the
windshield or windows. Do not place
containers such as air fresheners on
the instrument panel or dashboard.
Adhesive discs or containers may act
as lenses, causing a fire in the vehicle.
●Do not leave a door or window open if
the curved glass is coated with a met-
allized film such as a silver-colored
one. Reflected sunlight may cause the
glass to act as a lens, causing a fire.
●Always apply the parking brake, shift
the shift position to P, stop the engine
and lock the vehicle.
Do not leave the vehicle unattended
while the engine is running.
If the vehicle is parked with the shift
position in P but the parking brake is
not set, the vehicle may start to move,
possibly leading to an accident.
●Do not touch the exhaust pipes while
the engine is running or immediately
after turning the engine off.
Doing so may cause burns.
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, if
you accidentally move the shift lever or
depress the accelerator pedal, this could
cause an accident or fire due to engine
overheating. Additionally, if the vehicle is
parked in a poorly ventilated area,
exhaust gases may collect and enter the
vehicle, leading to death or a serious
health hazard.
■When braking
●When the brakes are wet, drive more
cautiously.
Braking distance increases when the
brakes are wet, and this may cause one
side of the vehicle to brake differently
than the other side. Also, the parking
brake may not securely hold the vehi-
cle.
●Vehicles without Lexus Safety System
+ A: If the brake booster device does
not operate, do not follow other vehi-
cles closely and avoid hills or sharp
turns that require braking.
In this case, braking is still possible, but
the brake pedal should be depressed
more firmly than usual. Also, the brak-
ing distance will in crease. Have your
brakes fixed immediately.
●Vehicles with Lexus Safety System + A:
If the electronically controlled brake
system does not operate, do not follow
other vehicles closely and avoid hills or
sharp turns that require braking.
In this case, braking is still possible, but
the brake pedal should be depressed
more firmly than usual. Also, the brak-
ing distance will in crease. Have your
brakes fixed immediately.
●Vehicles without Lexus Safety System
+ A: Do not pump the brake pedal if
the engine stalls.
Each push on the brake pedal uses up
the reserve for the power-assisted
brakes.
●Vehicles without Lexus Safety System
+ A: The brake system consists of 2
individual hydraulic systems; if one of
the systems fails, the other will still
operate. In this case, the brake pedal
should be depressed more firmly than
usual and the braking distance will
increase. Have your brakes fixed
immediately.
