STARTING AND DRIVING
107 For the best compromise between fuel economy and vehicle
performance, you should upshift or downshift at the following
speeds:
gear km/h (mph)
1 to 2 or 2 to 1 24 (15)
2 to 3 or 3 to 2 40 (25)
3 to 4 or 4 to 3 65 (40)
4 to 5 or 5 to 4 72 (45)
Downshift to the appropriate gear if acceleration is needed
when you are cruising below the above downshifting speeds.
Upshifting too soon or downshifting too late will cause lugging
and, possibly, pinging. Regularly revving the engine to
maximum speed in each gear will cause excessive engine
wear and high fuel consumption.
Maximum allowable speeds
To get on a highway or to pass slower traffic, maximum
acceleration may be necessary. Make sure you observe the
following maximum allowable speeds in each gear:
gear km/h (mph)
1 52 (32)
2 83 (52)
3 127 (79)
NOTICE:
Do not downshift if you are going faster than the
maximum allowable speed for the next lower gear.Good driving practice

If it is difficult to shift into reverse, put the transmission in
neutral, release the clutch pedal momentarily, and then try
again.

When towing a trailer, in order to maintain efficient engine
braking and electrical charging performance, do not use the
fifth gear.
CAUTION:
Be careful when downshifting on a slippery surface. The
abrupt change in engine speed could cause the vehicle to
spin or skid.
NOTICE:
Make sure the vehicle is completely stopped before
shifting into reverse.
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.

STARTING AND DRIVING
108CAUTION:

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.
Turning on the system
Control lever
Main switch
On
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.
Setting at a desired speed
Control lever
Main switch
Bring the vehicle to the desired speed, press the control lever
downward in the “SET/COAST” direction and release it. This
sets the vehicle at that speed. Now you may take your foot off
the accelerator pedal. If you need acceleration − for example,
when passing − depress the accelerator pedal enough for the
vehicle to exceed the set speed. When you release the
accelerator, the vehicle will return to the speed set prior to the
acceleration.

STARTING AND DRIVING
109 CAUTION (for manual transmission):
While driving with the cruise control on, do not shift to
neutral without depressing the clutch pedal, as this may
cause engine racing or overrevving. If this happens,
depress the clutch pedal or turn the main switch off
immediately.
Cancelling the preset speed
You can cancel the preset speed by:
a. Pulling the control lever in the “CANCEL” direction.
b. Depressing the brake pedal.
c. Depressing the clutch pedal (manual transmission)
If the vehicle speed falls below 40 km/h (25 mph), the preset
speed will automatically be cancelled.
If the vehicle speed drops 16 km/h (10 mph) below the preset
speed, the preset speed will also automatically be cancelled.
If the preset speed automatically cancels out for other than
these reasons, have your vehicle checked by your Lexus
dealer at the earliest opportunity.
Resetting to a faster speed
Press the control lever upward in the “RES/ACC” direction and
hold it. Release the lever when the desired speed is attained.
While the lever is held upward, the vehicle will gradually gain
speed.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
increased 1.6 km/h (1 mph) each time by pressing the control
lever upward in the “RES/ACC” direction quickly.
However, a quicker way to reset is to accelerate the vehicle
and then press the control lever downward in the “SET/
COAST” direction.
Resetting to a slower speed
Press the control lever downward in the “SET/COAST”
direction and hold it. Release the lever when the desired speed
is attained. While the lever is held downward, the vehicle
speed will gradually decrease.
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.
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
five times and then goes out when using the cruise control, it
means that there is trouble in the cruise control system.
Contact your Lexus dealer.
BRAKE SYSTEM
The tandem master cylinder brake system is a hydraulic
system with two separate sub-systems. If either sub-system
should fail, the other will still work. However, the pedal will be
harder to press, and your stopping distance will be longer.
Also, the brake system warning light may come on.
CAUTION:
Do not rely on a single brake system. Have your brakes
fixed immediately.
Brake booster
The brake booster uses engine vacuum to power-assist the
brakes. If the engine should quit while you are driving, you can
bring the vehicle to a stop with normal pedal pressure. There
is enough reserve vacuum for one or two stops but no more!
CAUTION:
Do not pump the brake pedal if the engine stalls. Each
push on the pedal uses up your vacuum reserve.
Even if the power assist is completely lost, the brakes
will still work. But you will have to push the pedal
hard−much harder than normal. And your braking
distance will be longer.
Anti-lock brake system
The anti-lock brake system is designed to prevent lock-up
of the wheels during sudden braking or braking on
slippery surfaces. This helps the vehicle remain steerable
and stable under these circumstances.
The system functions with normal pedal operation. When the
anti-lock function is in action, a pulsation of the brake pedal
may result, together with a characteristic noise. This indicates
that the system is functioning properly.
When driving with the anti-lock brake system, keep the
following in mind and adjust your driving according to the road
and traffic conditions

Even with the anti lock brake system, your vehicle still
requires a sufficient stopping distance. Always maintain a
safe distance from the vehicle in front of you.

Always slow down when cornering. The anti-lock brake
system cannot prevent accidents resulting from excessive
speeds.

On rough, gravel or snow-covered roads, etc., operation of
the anti-lock brake system may result in a longer stopping
distance than for vehicles not fitted with an anti-lock brake
system. Take this into account and reduce your speed.
