When either “L” or “R” of the mirror select switch is selected, the outside rear
view mirrors will automatically angle downwards when the vehicle is reversing in
order to give a better view of the ground. To disable this function, select neither
“L” nor “R”.

■

Adjusting the mirror angle when the vehicle is reversing

With the shift lever in R, adjust the mirror angle at a desired position. The
adjusted angle will be memorized and the mirror will automatically tilt to the
memorized angle whenever the shift lever is shifted to R from next time.

The memorized downward tilt position of the mirror is linked to the normal position

(angle adjusted with the shift lever in other than R). Therefore, if the normal posi-

tion is changed after adjustment, the tilt position will also change.
When the normal position is changed, readjust the angle in reversing.

■

Mirror angle can be adjusted when

The engine switch is in ACCESSORY or IGNITION ON mode.

■

When the mirrors are fogged up

The outside rear view mirrors can be cleared using the mirror defoggers. Turn on the

rear window defogger to turn on the outside rear view mirror defoggers. (

■

Automatic adjustment of the mirror angle

A desired mirror face angle can be entered to memory and recalled automatically by the

driving position memory. (

■

Auto anti-glare function

When the anti-glare inside rear view mirror is set to automatic mode, the outside rear

view mirrors will activate in conjunction with the anti-glare inside rear view mirror to

reduce reflected light. (

■

Using automatic mode in cold weather (if equipped)

When automatic mode is used in cold weather, the door mirror could freeze up and

automatic stowing and return may not be possible. In this event, remove any ice and snow

from the door mirror, then either operate the mirror using manual mode or move the mir-

ror by hand.

■

Driving in the rain

●

Drive carefully when it is raining, because visibility will be reduced, the windows may

become fogged-up, and the road will be slippery.

●

Drive carefully when it starts to rain, because the road surface will be especially slip-

pery.

●

Refrain 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.

■

Engine speed while driving

In the following conditions, the engine speed may become high while driving. This is due

to automatic up-shifting control or down-shifting implementation to meet driving condi-

tions. It does not indicate sudden acceleration.

●

The vehicle is judged to be driving uphill or downhill

●

Restraining engine output (Brake Override System)

●

When the accelerator and brake pedals are depressed at the same time, the engine

output may be restrained.

●

A warning message is displayed on the multi-information display while the system is

operating. (

P. 462)

■

Restraining sudden start (Drive-Start Control)

●

When the following unusual operation is performed, the engine output may be

• When the accelerator pedal is depressed too much while the vehicle is in reverse.

●

While Drive-Start Control is being activated, your vehicle may have trouble escaping

from the mud or fresh snow. In such case, deactivate TRAC (

P. 299) to cancel Drive-

Start Control so that the vehicle may become able to escape from the mud or fresh

snow.

■

Breaking in your new Lexus

To extend the life of the vehicle, observing the following precautions is recommended:

●

For the first 186 miles (300 km):

Avoid sudden stops.

●

For the first 621 miles (1000 km):
• Do not drive at extremely high speeds.

• Avoid sudden acceleration.

• Do not drive continuously in low gears.

• Do not drive at a constant speed for extended periods.

■

Drum-in-disc type parking brake system

Your vehicle has a drum-in-disc type parking brake system. This type of brake system

needs bedding-down of the brake shoes periodically or whenever the parking brake

shoes and/or drum are replaced. Have your Lexus dealer perform the bedding down

operation.

■

Operating your vehicle in a foreign country

Comply with the relevant vehicle registration laws and confirm the availability of the cor-

rect fuel. (



P. 519)

■

Brake pads and discs

●

F SPORT models of GS350, and GS F: The brake pads and discs are designed for use

under high load conditions. Therefore, brake noise may be generated depending on

the vehicle speed, braking force and vehicle environment (temperature, humidity, etc.).

●

GS F: In order to achieve steady braking performance even during high-load sporty

driving, brake pads that include a large amount of iron are used. As a result, rust may

form if the vehicle is parked for a long time with wet brake pads or disc rotors, causing

them to stick. When parts are stuck, abnormal noise or vibration may occur during

driving, so lightly depress the accelerator pedal and drive slowly. (Before parking the

vehicle after it is washed, drive slowly and apply the brakes several times to dry the

parts.)

191

iving

WARNING

Observe the following precautions.

Failure to do so may result in death or serious injury.

■

When starting the vehicle

Always keep your foot on the brake pedal while stopped with the engine running. This

prevents the vehicle from creeping.

■

When driving the vehicle

●

Do not drive if you are unfamiliar with the location of the brake and accelerator ped-

als to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake pedal will

result in sudden acceleration that may lead to an accident.

• When backing up, you may twist your body around, leading to a difficulty in oper-

ating the pedals. Make sure to operate the pedals properly.

• Make sure to keep a correct driving posture even when moving the vehicle only

slightly. This allows you to depress the brake and accelerator pedals properly.

• Depress the brake pedal using your right foot. Depressing the brake pedal using

your left foot may delay response in an emergency, resulting in an accident.

●

Do not drive the vehicle over or stop the vehicle near flammable materials.

The exhaust system and exhaust gases can be extremely hot. These hot parts may

cause a fire if there is any flammable material nearby.

●

During normal driving, do not turn off the engine. Turning the engine off while driving

will not cause loss of steering or braking control, but the power assist to these systems

will be lost. This will make it more difficult to steer and brake, so you should pull over

and stop the vehicle as soon as it is safe to do so.

However, in the event of an emergency, such as if it becomes impossible to stop the

vehicle in the normal way:



P. 425

●

Use 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 effective-

ness. (
