Before driving
CAUTION
■If the seat belt guide is disengaged
●Make sure that the seat belt guide is securely fixed before driving.
●After using the seatback fold and return switch, make sure that the seat belt
passes through the seat belt guide.
■Avoiding burns when using the seat heaters
●Use caution when seating the following pers ons in a seat with the seat heater on
to avoid the possibility of burns:
• Babies, small children, the elderly, the sick and the physically challenged
• Persons with sensitive skin
• Persons who are fatigued
• Persons who have taken alcohol or drugs that induce sleep (sleeping drugs,
cold remedies, etc.)
●Do not cover the seat with anything when using the seat heater.
Using the seat heater with a blanket or cushion increases the temperature of the
seat and may lead to overheating.
●Do not use the seat heater more than necessary. Doing so may cause minor
burns or overheating.
NOTICE
■To prevent seat heater damage
Do not put heavy objects that have an unev en surface on the seat and do not stick
sharp objects (needles, nail s, etc.) into the seat.
■To prevent battery discharge
Turn the seat heaters off when the engine is not running.

When driving
■When parking the vehicle
P. 1 1 0
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the
correct fuel. ( P. 3 6 0 )
CAUTION
■When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accelerator
pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerato r pedal instead of the brake pedal will
result in sudden acceleration that may le ad to an accident that could result in
death or serious injury.
• When backing up, you may twist your bo dy 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.
●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 flammable material nearby.
●If the smell of exhaust is noticed inside the vehicle, open the windows and check
that the rear hatch 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 your Lexus dealer immediately.
●Do not select Neutral while the vehicle is moving.
Doing so may cause insufficient engine braking, resulting in an accident.
●Do not turn the engine off while driving.
The power steering system will not operate properly if the engine is not running.
●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 effec-
tiveness.

2-1. Driving procedures

When driving
CAUTION
■When the vehicle is stopped
●Do not race the engine.
• If the vehicle is in any gear other than Neutral the vehicle may accelerate sud-denly and unexpectedly, causing an accident.
• Running the engine at high speed while the vehicle is stopped may cause the exhaust system to overheat, which could result in a fire if flammable material is
nearby.
• Racing the engine may emit loud noise, and possibly cause a nuisance, espe- cially after just starting the engine. This is because the structure of the exhaust
pipes cause the sound emitted from the exhaust to be louder than usual for
approximately 1 minute after the engine is started.
●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.
●If the vehicle is stopped on an incline, in order to prevent accidents caused by the
vehicle rolling forward or backward, always depress the brake pedal and securely
apply the parking brake as needed.
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in the vehi-
cle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and plastic material of glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the interior of
the vehicle, and may also cause a short circuit in the vehicle's electrical com-
ponents.
●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 wind shield or windows. Do not place contain-
ers such as air fresheners on the instru ment panel or dashboard. Adhesive discs
or containers may act as lenses, causing a fire in the vehicle.

2-1. Driving procedures
■Starting off control
The ASG does not have the creep function of a conventional automatic transmis-
sion. The vehicle can be driven by selecting 1st gear or Reverse and depressing the
accelerator pedal.
■Maximum speed for each gear
To avoid over-revving the engine, do not exceed the maximum speed for each gear
as shown below.
mph (km/h)
*: Always observe the legal speed limit when driving on public roads.
■Gear shift control
To ensure safety and driving performance, the following restrictions exist:
●Gear shifting with the paddle shift swit ches may not be possible under certain
driving conditions.
●Even while driving with a gear manually selected in SPORT, NORMAL, or
WET driving mode, the gears may change automatically under certain driving
conditions.
●If the paddle shift switches are operated repeatedly in a short space of time, a
temporary restriction of gear shifting may be activated. In this case, “Transmis-
sion pump overheat Shift rejected” will be displayed on the meter. ( P. 3 2 7 )
●Gear shifting with the paddle shift swit ches may not be possible when the trans-
mission fluid temperature is low. In this case, “Transmission temp low Shift
restricted” will be disp layed on the meter. (P. 3 2 7 )

■Outside temperature display
●The temperature display shows temperatures within the range of -40F (-40C)
and 122 F (50C).
●In the following situations, the correct outside temperature may not be dis-
played, or the display may take longer than normal to change:
• When the vehicle is stopped, or moving at low speeds (less than 15 mph [25
km/h])
• When the outside temperature has chan ged suddenly (at the entrance/exit of
a garage, tunnel, etc.)
●When “--” or “E” is displayed, the system may be malfunctioning. Take your vehi-
cle to your Lexus dealer.
NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone.
●The following may indicate that the engine is overheating. Immediately stop the
vehicle in a safe place.
• The display on the engine coolant temperature gauge flashes. (
P. 3 5 1 )
• The display on the engine oil temperature gauge flashes. (
P. 313)
●In the following situations, the engine may be malfunctioning. Immediately stop
the vehicle in a safe place and contact your Lexus dealer.
• The oil pressure gauge display does not show an increase even if the acceler-
ator pedal is depressed.
• The “Engine oil pressure low” warning message is displayed.
