CAUTION
nSRS airbag precautions
Observe the following precautions regarding the airbags.
Failure to do so may cause death or serious injury.
lThe driver and all passengers in the vehicle must wear their seat belts properly.
The SRS airbags are supplemental devices to be used with the seat belts.
lThe SRS driver airbag deploys with considerable force, and can cause death or
serious injury especially if the driver is very close to the airbag. The National
Highway Traffic Safety Administration (“NHTSA”) advises:
Since the risk zone for driver airbag is the first 2 - 3 in. (50 - 75 mm) of inflation,
placing yourself 10 in. (250 mm) from your driver airbag provides you with a
clear margin of safety. This distance is measured from the center of the steering
wheel to your breastbone. If you sit less than 10 in. (250 mm) away now, you can
change your driving position in several ways:

Before driving
CAUTION
nSRS airbag precautions
lIf the vinyl cover is put on the area where the SRS knee airbag will deploys, be
sure to remove it.
lDo not use seat accessories which cover the parts where the SRS side airbags
inflate as they may interfere with inflation of the airbags.
lDo not strike or apply significant levels of force to the area of the SRS airbag
components shown on P. 85.
Doing so can cause the SRS airbags to malfunction.
lDo not touch any of the component parts immediately after the SRS airbags have
deployed (inflated) as they may be hot.
lIf breathing becomes difficult after the SRS airbag has deployed, open a door or
window to allow fresh air in, or leave the vehicle if it is safe to do so. Wash off any
residue as soon as possible to prevent skin irritation.
lIf the areas where the SRS airbags are stored, such as the steering wheel pad and
front pillar garnish, are damaged or cracked, have them replaced by your Lexus
dealer.
lDo not attach anything to or lean anything
against areas such as the dashboard, steer-
ing wheel pad and lower portion of the
instrument panel.
These items can become projectiles when
SRS driver, front passenger and knee air-
bags deploy.
lDo not attach anything to areas such as the
door, windshield glass, side door glass,
front and rear pillars, roof side rail or assist
grip.
lDo not hang coat hangers or other hard
objects on the coat hooks. All of these
items could become projectiles and seri-
ously injure or kill you, should the SRS cur-
tain shield airbag deploy.

out consulting your Lexus dealer.
The SRS airbag may malfunction or deploy (inflate) accidentally, causing death or
serious injury.
lInstallation, removal, disassembly and repair of the SRS airbags
lRepairs, modifications, removal or replacement of the steering wheel, instrument
panel, dashboard, seats or seat upholstery, front, side and rear pillars or roof side
rails
lRepairs or modifications of the front fender, front bumper, or side of the occupant
compartment
lInstallation of snow plows, winches, etc. to the front grille (bull bars, kangaroo bar

2-1. Driving procedures
nStarting off on a hill (vehicles with an automatic transmission)
Hill-start assist control will operate. (→P. 1 8 6 )
nDriving in the rain
lDrive carefully when it is raining, because visibility will be reduced, the windows
may become fogged-up, and the road will be slippery.
lDrive carefully when it starts to rain, because the road surface will be especially
slippery.
lRefrain from high speeds when driving on an expressway in the rain, because
there may be a layer of water between the tires and the road surface, preventing
the steering and brakes from operating properly.
nBreaking in your new Lexus
To extend the life of the vehicle, the following precautions are recommended to
observe:
lFor the first 186 miles (300 km):
Avoid sudden stops.
lFor the first 621 miles (1000 km):

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.

When driving
CAUTION
nWhen driving on slippery road surfaces
lSudden braking, acceleration and steering may cause tire slippage and reduce
your ability to control the vehicle, resulting in an accident.
lSudden changes in engine speed, such as engine braking caused by up-shifting
or down-shifting, may cause the vehicle to skid, resulting in an accident.
lAfter driving through a puddle, 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 only one side are wet and not functioning
properly, steering control may be affected, resulting in an accident.
nWhen shifting the shift lever
With automatic transmission vehicles, be careful not to shift the shift lever with the
accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may cause an
accident and result in death or serious injury.
nWhen the vehicle is stopped
lDo not race the engine.
If the vehicle is in any gear other than P (vehicles with an automatic transmission
only) or N the vehicle may accelerate suddenly and unexpectedly, and may cause
an accident.
lDo 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 not enter the vehicle interior.
lWith automatic transmission vehicles, always keep a foot on the brake pedal
while the engine is running to prevent an accident caused by the vehicle moving.

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.
