2-1. Driving procedures

When driving on slippery road surfaces

Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle, resulting in an accident.

Sudden 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.

After 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, result-
ing in an accident.

When 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.

If you hear a squealing or scraping noise (brake pad wear indicators)
Have the brake pads checked and replaced by any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional, as soon as
possible.
Rotor damage can result if the pads are not replaced when needed.
Front brake only: Moderate levels of 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 those of the brake discs are exceeded.

When the vehicle is stopped

Do not race the engine.
If the vehicle is in any gear other than P (vehicles with an automatic trans-
mission only) 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 check that exhaust fumes do not enter the vehicle interior.
