belt height, and ou
tside rear view mirrors are adjus ted to memorized

trol or the smart access system, if equipped.
The tilt and telescopic steering column position is ad justed to the memo-
rized position when you push the ignitio n switch, or inser
t the key into the

■To change the memorized position
Adjust the desired positions of the driver ’
s seat, tilt and telescopic steering
column and outside mirrors.
Push the “SET” button and the “1”, “2” or “3” button at the same time until
you hear a beep.

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.

on slippery road surfaces.
■ BA (Brake Assist)

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)

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.
