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.

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.
