Before driving
CAUTION
nSeat adjustment
lDo 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,
increasing the risk of death or serious injury in the event of an accident.
lManual seat only: After adjusting the seat, make sure that the seat is locked in
position.

Before driving
Steering wheel (power-adjustable type)
Auto tilt away
When the “ENGINE START
STOP” switch is turned OFF, the
steering wheel returns to its
stowed position by moving up and
away to enable easier driver entry
and exit.
Switching to ACCESSORY or
IGNITION ON mode will return
the steering wheel to the original
position.
The steering wheel can be adjusted to a comfortable position.

1-7. Safety information
In certain types of severe frontal or side impacts, the SRS airbag system
triggers the airbag inflators. A chemical reaction in the inflators quickly
fills the airbags with non-toxic gas to help restrain the motion of the occu-
pants.
nSRS warning light
This warning light system monitors the airbag sensor assembly, front airbag sensors,
side and curtain shield airbag sensor assemblies, curtain shield airbag sensor
assemblies, driver's seat position sensor, driver's seat belt buckle switch, seat belt
pretensioner assemblies, inflators, interconnecting wiring and power sources.
(→P. 3 8 4 )
nIf the SRS airbags deploy (inflate)
lBruising and slight abrasions may result from contact with a deploying (inflating)
SRS airbag.
lA loud noise and white powder will be emitted.
lParts of the airbag module (steering wheel, airbag cover and inflator) as well as
the front seats, and parts of the front pillar, rear pillar and roof side rail, may be
hot for several minutes. The airbag itself may also be hot.
lThe windshield may crack.
nOperating conditions (front airbags)
lThe SRS front airbags will deploy if the severity of the frontal impact is above the
designed threshold level, comparable to an approximate 15 mph (25 km/h) col-
lision when the vehicle impacts straight into a fixed barrier that does not move
or deform.
However, this threshold velocity will be considerably higher if the vehicle strikes
an object, such as a parked vehicle or sign pole, which can move or deform on
impact, or if the vehicle is involved in an underride collision (e.g. a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a truck, etc.).
lIt is possible that in some collisions where the forward deceleration of the vehi-
cle is very close to the designed threshold level, the SRS front airbags and the
seat belt pretensioners may not activate together.
lThe SRS front passenger airbag will not activate if there is no passenger sitting
in the front passenger seat. However, the front passenger airbag may deploy if
luggage is put in the seat, or the seat belt is fastened, even if the seat is unoccu-
pied. (→P. 9 5 )

2-1. Driving procedures
CAUTION
lDo not turn the engine off while driving.
The power steering and brake booster system will not operate properly if the
engine is not running.
lUse 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. 1 3 2 )
lWhen 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.
lDo not adjust the position 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 that may
result in death or serious injury.
lAlways check that all passengers' arms, heads or other parts of their bodies are
not outside the vehicle, as this may result in death or serious injury.
lDo not drive the vehicle off-road.
This is not a AWD vehicle designed for real off-road driving. Proceed with all due
caution if it becomes unavoidable to drive off-road.
lDo not drive across river crossings or through other bodies of water.
This may cause electric/electronic components to short circuit, damage the
engine or cause other serious damage to the vehicle.
lDo not drive in excess of the speed limit. Even if the legal speed limit permits it, do
not drive over 85 mph (140 km/h) unless your vehicle has high-speed capability
tires. Driving over 85 mph (140 km/h) may result in tire failure, loss of control and
possible injury. Be sure to consult a tire dealer to determine whether the tires on
your vehicle are high-speed capability tires or not before driving at such speeds.

2-1. Driving procedures
NOTICE
nWhen driving the vehicle
With automatic transmission vehicles
lDo not use the accelerator pedal or depress accelerator and brake pedals
together to hold the vehicle on a hill.
With manual transmission vehicles
lDo not rest your foot on the clutch pedal while driving.
Doing so may cause clutch trouble.
lDo not use any gears other than the first gear when starting off and moving for-
ward.
Doing so may damage the clutch.
lDo not use the clutch to hold the vehicle when stopping on an uphill grade.
nWhen parking the vehicle
With automatic transmission vehicles, always put the shift lever in P. Failure to do so
may cause the vehicle to move or the vehicle may accelerate suddenly if the accel-
erator pedal is accidentally depressed.
nAvoiding damage to vehicle parts
lDo not turn the steering wheel fully in either direction and hold it there for a long
time.
Doing so may damage the power steering motor.
lWhen driving over bumps in the road, drive as slowly as possible to avoid damag-
ing the wheels, underside of the vehicle, etc.

When driving
NOTICE
nIf you hear a squealing or scraping noise (brake pad wear limit indicators)
Have your Lexus dealer check and replace the brake pads as soon as possible.
The rotor damage can result if the pads are not replaced when needed.
Front brake only: Moderate levels of the brake pad and disc wear allow enhanced
front 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 thickness of the discs measured.
It is dangerous to drive the vehicle when the wear limits of the brake pads and/or
that of the brake discs are exceeded.
nIf you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering wheel
firmly and gradually press the brake pedal to slow down the vehicle.
lIt may be difficult to control your vehicle.
lThe vehicle will make abnormal sounds.
lThe vehicle will behave abnormally.
Replace a flat tire with a new one. (→P. 4 0 6 )
nWhen encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may cause the
following serious damage to the vehicle.
lEngine stalling
lShort in electrical components
lEngine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be sure to
have your Lexus dealer check the following.
lBrake function
lChanges in quantity and quality of oil and fluid used for the engine, transmission,
transfer (AWD vehicles), differential, etc.
lLubricant condition for the propeller shaft (AWD vehicles), bearings and suspen-
sion joints (where possible) and the function of all joints, bearings, etc.
