NOTE: *The volume or interval of beep sound can be changed.
Ask your Lexus dealer for details.
31L0031
”LOCK” Engine is off and the steering wheel is locked. The
ignition key can be removed only at this position.
To turn the key from ”ACC” to the ”LOCK” position, you must put
the transmission selector lever in the ”P” position.
Once you remove the key, the engine immobiliser system is
automatically set. See ”Engine immobiliser system” on page 10.
When starting the engine, the key may seem stuck at the ”LOCK”
position. To free it, first be sure the key is pushed all the way in, and
then rock the steering wheel slightly while turning the key gently.
If, in an emergency, you must turn the engine off while the vehicle
is moving, turn the key only to ”ACC”.
PARKING BRAKE
31L005

To set: Fully depress the parking brake pedal.
2
To release: Pull the parking brake release lever.
Before leaving your vehicle, firmly apply the parking brake.
CAUTION
Before driving, make sure the parking brake is fully released
and that the parking brake reminder light is off.

STARTING AND DRIVING

AUTOMATIC TRANSMISSION
Your automatic transmission has a shift lock system to minimize
the possibility of incorrect operation. This means you can only
shift out of ”P” position when the brake pedal is depressed with
the ignition switch in ”ON” position. ( )
31L078
The shift position is displayed on the instrument cluster.P:Parking, engine starting and key removal position
R:Reverse position
N:Neutral position
D:Normal driving position (Shifting into overdrive possible)
4:Position for engine braking (Shifting into overdrive not
possible)
When the cruise control is being used, even if you downshift
from ”D” to ”4”, engine braking will not be applied because
the cruise control is not cancelled. For the operation to
decrease the vehicle speed, see page 170.

L:Position for maximum engine braking

STARTING AND DRIVING
161 Correct use of the automatic transmission is explained in the
following parts.
(a) Normal driving
(b) Using engine braking
(c) Using the ”3”, ”2” and ”L” positions
(d) Backing up
(e) Parking
(f) Good driving practice
(g) Rocking your vehicle if stuck
(h) If you cannot shift the selector lever
(i) If the ”ECT PWR” indicator light flashes
(a) Normal driving

”P” (Park) position 2
”N” (Neutral) position
1. Start the engine as instructed in ”How to start the engine” on
page 159.
The transmission must be in ”P” or ”N”. The engine will not start
in any drive position even if the ignition key is turned to ”START”.

Power mode 2
Normal mode 3
Snow mode
2. Set the driving pattern selector switch to the ”Normal”
position.
Your transmission has a driving pattern selector switch which allows
you to select ”Power”, ”Normal” or ”Snow” mode to suit your
driving condition. For ordinary driving, Lexus recommends that
you use the ”Normal” position to improve fuel economy.
3. For more powerful acceleration and sporty driving, use the
”Power” position.
In the POWER position, the ”ECT PWR” light in the instrument
cluster is on and the transmission is shifted up at higher vehicle
speeds and shifted down more responsively than in the NORMAL
position.
For ”Snow” mode, see ”Electronic Throttle Control System” on
page 167.

”D” (Drive) position 2
Brake pedal
4. With your foot holding down the brake pedal, shift the
selector lever to ”D”.
Always use the ”D” position to improve fuel economy and quiet
driving. Only in this position, shifting into the overdrive gear is
possible. However, while the engine coolant temperature is low, the
transmission will not shift into the overdrive gear even in the ”D”
position. (See ”(b) Using engine braking” and ”(f) Good driving
practice” for exceptions.)
CAUTION
Never put your foot on the accelerator pedal while shifting.
