The gauge indicates the engine cool-
ant temperature when the ignition
switch is on. The engine operating
temperature will vary with changes inweather and engine load.
If the needle moves into the red zone, your engine is too hot. If your vehicle
overheats, stop your vehicle and allow the
engine to cool.
Your vehicle may overheat during severe operating conditions, such as: Driving up a long hill on a hot day.
Reducing speed or stopping after high
speed driving.
Idling for a long period with the air con-
ditioning on in stop-and-go traffic.
Towing a trailer
NOTICE
Do not remove the thermostat in
the engine cooling system as this
may cause the engine to overheat. The thermostat is designed tocontrol the flow of coolant to keep
the temperature of the engine within the specified operatingrange.
Do not continue driving with an
overheated engine. See If yourvehicle overheatsº in Part 4.The tachometer indicates engine
speed in thousands of rpm (revolu-
tions per minute). Use it while driving
to select correct shift points and to
prevent engine lugging and overrev- ving.
Driving with the engine running too fast
causes excessive engine wear and poor
fuel economy. Remember, in most cases
the slower the engine speed, the greater
the fuel economy.
NOTICE
Do not let the indicator needle get into the red zone. This may cause
severe engine damage.

Your automatic transmission has a shift
lock system to minimize the possibility of
incorrect operation. This means you can
only shift out of Pº position when the brake
pedal is depressed (with the ignition
switch in ONº position and the selector le-ver pulled toward you).
(a) Normal Driving
1. Start the engine as instructed in How
to start the engineº in Part 3. The trans- mission must be in Pº or Nº.
2. With your foot holding down the brake pedal, shift the selector lever to Dº.
In Dº position, the automatic transmis-
sion system will select the most suitable
gear for running conditions such as nor-
mal cruising, hill climbing, hard towing, etc.
Always turn the overdrive switch on for
better fuel economy and quieter driving. If
the engine coolant temperature is low, thetransmission will not shift into overdrive
gear even with the overdrive switch on.
Never put your foot on the accelera-
tor pedal while shifting. CAUTION
! 3. Release the parking brake and brake
pedal. Depress the accelerator pedal
slowly for smooth starting.
(b) Using engine braking
To use engine braking, you can downshift the transmission as follows: Turn off the overdrive switch. The O/D
OFFº indicator light will come on and the transmission will downshift to the
third gear.
Shift into the 2º position). The trans-
mission will downshift to the second
gear when the vehicle speed drops down to or lower than the followingspeed, and more powerful engine
braking will be obtained.
3RZ-FE engine 112 km/h (69 mph) . .
5VZ-FE engine 119 km/h (73 mph) . .
Shift into the Lº position. The trans-
mission will downshift to the first gear.
When the vehicle speed drops down to
or lower than the following speed, and
maximum engine braking will be ap- plied.
3RZ-FE engine 54 km/h (33 mph) . . .
5VZ-FE engine 58 km/h (36 mph) . . . Vehicles with cruise controlÐWhen the
cruise control is being used, even if you
downshift the transmission by turning off
the overdrive switch, engine braking is not
applied because the cruise control is not cancelled.
For ways to decrease the vehicle speed,
see Cruise controlº in this chapter.
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin orskid.
CAUTION

(c) Using the 2º and Lº positions
The 2º and Lº positions are used for
strong engine braking as described pre-
viously. With the selector lever in 2º or Lº, you
can start the vehicle in motion as with the
lever in Dº. With the selector lever in 2º, the vehicle
will start in the first gear and automatically
shift to the second gear.
With the selector lever in Lº, the trans-
mission is engaged in the first gear.
