STARTING AND DRIVING

(e) Good driving practice

If the transmission repeatedly upshifts and downshifts
between the third and overdrive gears when climbing a
gentle slope, shift the selector lever to the “3” position. Be
sure to shift the selector lever to the “D” position after
climbing the slope.

When towing a trailer, in order to maintain efficient engine
braking and electrical charging performance, do not use
overdrive. The selector lever must be in the “3” position.
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.
(f) If you cannot shift the selector lever
If you cannot shift the selector ever 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 175.
(g) If the “ECT PWR” indicator light flashes
If the “ECI PWR” 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 great
speed change will occur so it is better to drive without the cruise
control.
When the cruse control is on, the driving pattern of the
automatic transmission is fixed in the normal position,
regardless of the position of the selector switch.

STARTING AND DRIVING

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. If the vehicle speed is too fast in relation to
the cruise control set speed, cancel the cruise
control then downshift the transmission to use
engine braking to slow down.
Turning on the system
CRUISE
To operate the cruise control, push the main switch. This turns
the system on. The indicator light in the instrument cluster
shows that you can now set your desired cruising speed.
Another push on the switch will turn the system completely off.
When the ignition key is turned off, the main switch is also
automatically turned off. To use the cruise control again, push
the main switch again to turn it on.
CAUTION
To avoid accidental cruise control engagement, keep
the main switch off when not using the cruise control.

STARTING AND DRIVING
139 When the difference between the actual vehicle speed and the
set speed is less than 5 km / h (3 mph), the set speed can be
lowered 1.6 km / h (1 mph) each time by pressing the control
lever downward in the “SET / COAST” direction quickly within
0.6 seconds.
However, a quicker way to reset is to depress the brake pedal
and then press the control lever downward in the
“SET / COAST” direction.
Resuming the preset speed
Press the control lever upward in the “RES / ACC” direction.
The vehicle will resume the speed set prior to cancellation
unless the vehicle speed is less than 40 km / h (25 mph) or is
16 km / h (10 mph) below the preset speed.
Cruise control failure warning
If the “CRUISE” indicator light in the instrument cluster flashes
when using the cruise control, push the main switch to turn the
system off and then push it again to turn it on.
If any of the following conditions then occurs, there is some
trouble in the cruise control system.

The indicator light does not come on.

The indicator light flashes again.

The indicator light goes out after it comes on.
If this is the case, contact your Lexus dealer and have your
Lexus inspected.
ELECTRONICALLY MODULATED
AIR SUSPENSION
(U.S.A. ONLY)
This electronically modulated air suspension adjusts the
damping effect on the shock absorbers and the vehicle
height. This adjustment is automatically made in
response to the driving conditions to provide good riding
comfort and stability in all driving conditions.
(a) Vehicle height adjustment
This system maintains a stable vehicle height, regardless
of occupants and luggage weight. You can select one of
the following modes using a selector switch.
