■

Driving on a downhill
On declines, there may be case where the vehicle shifts down automatically to obtain

engine braking. As a result of the downshifting, the engine speed may increase.

■

Second start mode automatic deactivation
Second start mode is automatically deactivated if the engine is turned off after driving in

second start mode.

■

S mode
When the shift range is 5 or lower, holding the shift lever toward “+” sets the shift range to

■

AI-SHIFT
AI-SHIFT automatically shifts the gear to the suitable position according to driver perfor-

mance and driving conditions.
AI-SHIFT automatically operates when the shift lever is in the D position. (Shifting the

shift lever to the S position cancels the function.)

■

When driving with the cruise control or dynamic radar cruise control
Engine braking will not occur in S mode, even when downshifting to 5 or 4.

(

P. 229, 232)

■

Shift lock system
The shift lock system is a system to prevent accidental operation of the shift lever in start-

ing.
The shift lever can be shifted from P only when the engine switch is in the IGNITION ON

mode and the brake pedal is being depressed.

202

■

If the shift lever cannot be shifted from P
First, check whether the brake pedal is being depressed.
If the shift lever cannot be shifted with your foot on the brake pedal, there may be a prob-

lem with the shift lock system. Have the vehicle inspected by your Lexus dealer, immedi-

ately.

The following steps may be used as an emergency measure to ensure that the shift lever

can be shifted.
Releasing the shift lock:

Set the parking brake.
Turn the engine switch off.
Depress the brake pedal.

■

If the “S” indicator does not come on even after shifting the shift lever to S
This may indicate a malfunction in the automatic transmission system. Have the vehicle

inspected by your Lexus dealer immediately.

(In this situation, the transmission will operate in the same manner as when the shift lever

is in D.)

■

Downshift restriction warning buzzer (S mode)
To help ensure safety and driving performance, downshifting operation may sometimes

be restricted. In some circumstances, downshifting may not be possible even when the

shift lever is operated. (A buzzer will sound twice.)

Pry the cover up with a flathead screwdriver

or tool.

Press the shift lock override button.
The shift lever can be shifted while the button

is pressed.

CAUTION

■

When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.

Sudden changes in engine braking may cause the vehicle to spin or skid, resulting in an

accident.

■

To prevent an accident when releasing the shift lock
Before pressing the shift lock override button, make sure to set the parking brake and

depress the brake pedal.
If the accelerator pedal is accidentally depressed instead of the brake pedal when the

shift lock override button is pressed and the shift lever is shifted out of P, the vehicle

may suddenly start, possibly leading to an accident resulting in death or serious injury.

Daytime running light system

●

The daytime running lights illuminate using the same lights as the parking lights and illu-

minate brighter than the parking lights.

●

To make your vehicle more visible to other drivers during daytime driving, the daytime

running lights turn on automatically when all of the following conditions are met. (The

daytime running lights are not designed for use at night.)
• The engine is running

• The parking brake is released
• The headlight switch is in the

(type B only),

or “AUTO”* position

: When the surroundings are bright

The daytime running lights remain on after they illuminate even if the parking brake is

set again.

●

For the U.S.A.: Daytime running lights can be turned off by operating the switch.

●

Compared to turning on the headlights, the daytime running light system offers greater

durability and consumes less electricity, so it can help improve fuel economy.

gers and the loading condition of the vehicle to ensure that the headlights do not inter-

fere with other road users.
