position
5. With your foot holding down the brake pedal, shift the
selector lever to “D”.
CAUTION:
Never put your foot on the accelerator pedal while
shifting.
6. Release the parking brake and brake pedal. Depress the
accelerator pedal slowly for smooth starting.
The vehicle will start in the first gear and automatically shift to
the most suitable gear for the running conditions, such as the
vehicle speed, hill climbing, hard towing, etc. However, while
the engine coolant temperature is low and the vehicle is
traveling at low speed, the transmission will not shift into the
overdrive gear even with the overdrive switch on.
In “D” position, the automatic transmission system will select
the most suitable gear for the running conditions such as hill
climbing, hard towing, etc.

STARTING AND DRIVING

NOTICE:

Be careful not to overrev the engine. Watch the
tachometer to keep engine rpm from going into the
red zone. The approximate maximum allowable
speed for each position is given below for your
reference:
“2” ... 121 km / h (75 mph)
“L” ... 67 km / h (42 mph)

Do not continue hill climbing or hard towing for a long
time in the “2” or “L” position. This may cause severe
automatic transmission damage from overheating. To
prevent such damage, “D” position should be used in
hill climbing or hard towing.

CAUTION:
While the vehicle is in motion, never attempt to move the
selector lever into “P” under any circumstances. Serious
mechanical damage and loss of vehicle control may
result.

(f) Good driving practice

If the transmission repeatedly upshifts and downshifts
between the third and overdrive gears when climbing a
gentle slope, it is suggested that the overdrive switch be
turned off. Be sure to turn the switch on immediately
afterward.

When towing a trailer, in order to maintain efficient engine
braking and electrical charging performance, do not use
overdrive.
CAUTION:
Always keep your foot on the brake pedal while stopped
with the engine running. This prevents the vehicle from
creeping.
NOTICE:
Do not hold the vehicle on an upgrade with the
accelerator pedal. This can cause the transmission to
overheat. Always use the brake pedal or parking brake.
(g) If you cannot shift the selector lever out
of “P” position
If you cannot shift the selector lever from “P” position even
though the brake pedal is depressed, use the shift lock
override button. For instructions, see “If you cannot shift
automatic transmission selector lever” on page 163.
(h) If the “O / D OFF” indicator light flashes
If the “O / D OFF” indicator light flashes, contact your Lexus
dealer as soon as possible. There may be trouble in the
transmission system.
CRUISE CONTROL
The cruise control allows you to cruise the vehicle at a
desired speed over 40 km / h (25 mph) with your foot off the
accelerator pedal.
Your cruising speed can be maintained although a slight speed
change may occur when driving up or down a gradient, within
the limits of engine performance. On steeper hills, a greater
speed change will occur so it is better to drive without the cruise
control.
When the cruise control is on, the driving pattern of the
automatic transmission is fixed in the normal position,
regardless of the position of the selector switch.
CAUTION:

To help maintain maximum control of your vehicle, do
not use the cruise control when driving in heavy or
varying traffic, or on slippery (rainy, icy or
snow-covered) or winding roads.

Avoid vehicle speed increases when driving downhill.
Use engine braking by downshifting the transmission.

STARTING AND DRIVING
133 “HIGH” mode
The vehicle height switches between the following two vehicle
heights according to the driving conditions:
Vehicle height
Driving condition
NormalHigh-speed driving
HighLow and medium speed driving
The indicator light shows the vehicle height is high.
When you turn the ignition key to the “ON” position, the
indicator light will come on for 2 seconds.
(b) Height control ON / OFF switch
OnOff
This switch is located inside the tool storage section on the left
side of the trunk compartment. Sliding the switch to the OFF
position will turn off the height control system. When the switch
is turned off, the “HI” display plinks.
NOTICE:
Before jacking up, towing or hoisting the vehicle, always
turn the height control ON / OFF switch to OFF. If this is
not done, the vehicle height automatic adjustment
function will operate, causing imbalance of the vehicle
and contact of the bumper, etc. with the road surface.
(c) Malfunction warning
If the “HI” display blinks when the height control ON / OFF
switch is turned on, there is a malfunction in the Lexus ride
control system or height control system.
