When driving
CAUTION
■When driving the vehicle
●Do not drive if you are unfaniliar with the location of the brake and accelerator
pedals to avoid depressing the wrong pedal. 
Accidentally depressing the accelerator pedal instead of the brake pedal will
r
esult in sudden acceleration that may lead to an accident that could result in
death or serious injury.
●Do not drive the vehicle over or stop the vehicle near flammable materials.
●Do not let the vehicle roll backwards while the selector lever is in a driving posi -
tion, or roll forward while the selector lever is in R. 
Doing so may cause the engine to stall or lea
d to poor brake and steering perfor-
mance, resulting in an accident or damage to the vehicle.
●If you smell exhaust fumes in the vehicle, open the windows and close the trunk lid
to ensure plenty of fresh air enters the vehicle.
If you can smell exhaust fumes even through there are no other vehicle in sur -
rounding area, have your vehicle checke d b
y you Lexus dealer. Continued inhala-
tion of exhaust fumes can lead to death by gas poisoning.
●Do not shift the selector lever to P, R or N while the vehicle is moving under any
circumstances. 
Doing so can cause significant damage to the tr
ansmission system and may result
in a loss of vehicle control.
●Do not turn the engine off while driving. 
The power steering and brake booster systems will not operate properly if the
eng
ine is not running.
●Use the 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. ( P.98 )
●Do not shift the selector lever to N. 
Doing so may cause the engine brake to not operate properly and lead to an
acc
ident.
●When stopped on an inclined surface, use the brake pedal and parking brake to
prevent the vehicle from rolling backward or forward and causing an accident.

2-1. Driving procedures
CAUTION
■While driving the vehicle
●Be careful when driving on slippery surfaces, as the vehicle may skid or spin when
downshifting, rapidly accelerating, braking or turning.
●Do not adjust the position of the steering wheel, seat, or mirror while driving.
Doing so may result in losing control of th
e vehicle and cause an accident, which
may cause death or serious injury.
●Always check that passengers’ arms, heads or other parts of their bodies are not
outside the vehicle, as this may result in death or serious injury.
■When shifting the selector lever
Use caution if accelerating while shifting. 
This may lead to unexpected rapid acceleration of the vehicle that may cause an
ac
cident.
■When the vehicle is stopped
●Do not race the engine. 
If the vehicle is in any gear other than P or N the
vehicle may accelerate suddenly
and unexpectedly, and may cause an accident.
●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
che
ck that exhaust fumes do no t enter the vehicle interior.
●Always keep a foot on the brake pedal while the engine is running to prevent an
accident caused by the vehicle moving.

2-4. Using other driving systems
Driver assist systems
When VSC or TRAC is operating
If the vehicle is in danger of slip-
ping or the rear wheels spin, the
slip indicator ligh t flash to indicate
that the s

ystems have been
engaged.
A buzzer (intermittent) sounds
when VSC is operating.
To help enhance improve vehicle safety, the following systems operate auto-
matically in certain driving conditions.
■ ABS (Anti-lock Braking System)
Help ensure steering performance in th e event of sudden braking or driving
on slippery road surfaces.
■ BA (Brake Assist)
Generates an increased level of braking force after the brake pedal is
pushed, when the system detects a panic stop situation.
■VSC (Vehicle Stability Control)
Helps the driver to control skidding wh en swerving suddenly or turning on
slippery road surfaces.
■ TRAC (Traction Control)
Helps maintain drive power and prevents spinning the rear wheels when
starting the vehicle or accelerating on slippery roads.
■Pre-collision system (if equipped)
( P. 1 4 3 )

■Operating sounds and vibrations caus ed by the ABS, VSC & TRAC systems
●A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indicate that
a malfunction has occurred in any of these systems.
●Any of the following conditions may occur when the ABS, VSC and TRAC sys -
tems are operating. None of these indicates that a malfunction has occurred.
• A sound may be heard.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly while the ABS is activated.
• The brake pedal may move forward slightly after the ABS is activated.

When driving
As shown in the above example, if the number of occupants increases,
the cargo and luggage load equaling the combined weight of the occu-
pants who got on later, by an amount. In other w
ords, if an increase in the
number of occupants causes an excess of the total load capacity (com -
bined weight of occupants plus car go and luggage load), y
ou must
reduce the cargo and luggage on your vehicle. ( P.148 )
CAUTION
■Storage precautions
●Do not place anything on the packag e tray behind the rear seatback. 
Such items may be thrown about and possib ly injur
e people in the vehicle during
sudden braking or in an accident.
●Do not drive with objects on top of the instrument panel. 
They may interfere with the driver’s field of view or move during sharp accelera -
tion or turning, thus impairing the driver ’
s control of the vehicle. In an accident
they may injure the vehicle occupants.
●Secure all items in the occupant compartment, as they may shift and injure some -
one during an accident or sudden braking.
■Weight of the load
●Improper loading may cause deterioratio n of steering or braking control result-
ing in an accident which may cause death or serious injury.
●Do not exceed the maximum axle weight ra ting or the total vehicle weight rating.
●Even if the total load of occupant's weight and the cargo load is less than the total
load capacity, do not apply the load unevenly.
