CAUTION

■

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, resulting 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 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

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 transmission

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.

●

With automatic transmission vehicles, in order to prevent accidents due to the

vehicle rolling away, always keep depressing the brake pedal while the engine is

running, and apply the parking brake as necessary.
