operate when the driver exits the vehicle.
■Customization
The power easy access system can be activated/deactivated.
(Customizable features P. 383)
CAUTION
■Seat adjustment
Do not recline the seat more than necessary when the vehicle is in motion to reduce
the risk of sliding under the lap belt.
If the seat is too reclined, the lap belt may slide past the hips and apply restraint
forces directly to the abdomen or your neck may contact the shoulder belt, increas-
ing the risk of death or serious in jury in the event of an accident.
■Seatback fold and return switch
Never operate the seat fold switch while the seat is occupied, as the occupant may
become jammed in the seat, resulting in serious injury.

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.

92
2-1. Driving procedures
CAUTION
●Do not adjust the positions of the steering wheel, the seat, or the inside or outside
rear view mirrors while driving.
Doing so may result in a loss of vehicle control that can cause accidents, resulting
in death or serious injury.
●Always check that all occupants’ arms, heads and other body parts are not out-
side the vehicle, as this may result in death or serious injury.
■When driving on slippery road surfaces
●Sudden braking, acceleration and steer ing may cause tire slippage and reduce
your ability to control the vehi cle, resulting in an accident.
●Sudden changes in engine speed, such as engine braking caused by up-shifting
and down-shifting, may cause the vehicle to skid, resulting in an accident.
●After driving through a pudd le, 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 operating the paddle shift switches/reverse selector switch
Do not operate the paddle shift switches or reverse selector switch with the accel-
erator pedal depressed and Neutral selected.
Doing so may lead to unexpected rapid acceleration of the vehicle that may cause
an accident and result in death or serious injury.
■If a brake pad wear warning message is displayed
Have your Lexus dealer check and replac e the brake pads as soon as possible.
The disc damage can result if the pads are not replaced when needed.
Moderate levels of the brake pad and disc wear allow enhanced 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 thick-
ness 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.

2-1. Driving procedures
NOTICE
■When driving the vehicle
●Do not depress the accelerator and brake pedals at the same time during driving.
If the brake pedal is depressed whil e driving with the accelerator pedal
depressed, driving torque may be restrained.
●Do not use the accelerator pedal or depress the accelerator and brake pedals at
the same time to hold the vehicle on a hill. Doing so may damage the clutch.
■When parking the vehicle
●Parking with the rear of the vehicle close to a wall or similar structure may cause
the area around the exhaust pipes to over heat. As this may result in damage to
the rear bumper or other components, be sure to park the vehicle rear end as far
away as possible from walls and other such structures.
●When it rains, do not park on a slope with an angle of 15 degrees or more, as rain-
water may enter the vehicle. If parking at such an angle is unavoidable, use wheel
chocks and place a car cover over the vehicle.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for an
extended period of time.
Doing so may damage the power steering motor.
●When driving over bumps in the road, be careful and drive as slowly as possible
to avoid damaging the wheels, tires, underside of the vehicle, etc.
■If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering wheel
firmly and gradually depress the brak e pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean.

2-4. Using other driving systems
Driving assist systems
To help enhance driving safety and performance, the following systems oper-
ate automatically in response to various driving situations. Be aware, however,
that these systems are supplementary and should not be relied upon too
heavily when operating the vehicle.
■ ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the br akes are applied suddenly, or if the
brakes are applied while driving on a slippery road surface.
■ Brake assist
Generates an increased level of braking force after the brake pedal is
depressed when the system de tects a panic stop situation.
■VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning on
slippery road surfaces.
■ TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spinning
when starting the vehicle or accelerating on slippery roads.
■Hill-start assist control
Helps to reduce the vehicle’s rolling backward distance when starting on an
incline or slippery slope.
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn the
steering wheel.
■VDIM (Vehicle Dynamics Integrated Management)
Provides integrated control of the ABS, brake assist, VSC, TRAC, and hill-
start assist control systems.
Helps to maintain vehicle stability when swerving on slippery road surfaces
by controlling the brakes and engine output.
When switched to SPORT driving mode, the control characteristics of the
VDIM system are altered.
