2001 TOYOTA COROLLA engine overheat

The gauge indicates the engine coolant
temperature when the ignition switch is
on. The engine operating temperature
will vary with changes in weather 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
conditioning 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 to con-
trol the flow of coolant to keep the
temperature of the engine within
the specified operating range.
Do not continue driving with an
overheated engine. See ªIf your ve-
hicle overheatsº in Section 4.
Tachometer
The tachometer indicates engine speed
in thousands of rpm (revolutions per
minute). Use it while driving to select
correct shift points and to prevent en-
gine lugging and over±revving.
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.

(b) Normal driving
1. Start the engine as instructed in ªHow
to start the engineº in Section 3. The
transmission must be in ªPº or ªNº.
2. With your foot holding down the brake
pedal, shift the selector lever to ªDº.
When the lever is in the ªDº position, the
automatic transmission system will select
the most suitable gear for running condi-
tions such as normal cruising, hill climb-
ing, hard towing, etc.
CAUTION
Never put your foot on the accelera-
tor pedal while shifting.
3. Release the parking brake and brake
pedal. Depress the accelerator pedal
slowly for smooth starting
(c) Using engine braking
To use engine braking, you can downshift
the transmission as follows:
Shift into the ª2º position when the
vehicle speed is lower than 103 km/h
(64 mph). The transmission will down-
shift to second gear and stronger en-
gine braking will be enabled.
Shift into the ªLº position when the
vehicle speed is lower than 49 km/h
(30 mph). The transmission will down-
shift to first gear and maximum engine
braking will be enabled.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin or
skid.
(d) Using ª2º and ªLº position
The ª2º and ªLº positions are used for
strong engine braking as described pre-
viously.
With the selector lever in ª2º or ªLº, you
can start the vehicle in motion as with the
lever in ªDº.
With the selector lever in ª2º, the vehicle
will start in first gear and automatically
shift to second gear.
With the selector lever in ªLº, the trans-
mission is engaged in first gear.
NOTICE
Be careful not to over±rev the en-
gine. Watch the tachometer to keep
engine rpm from going into the red
zone. The approximate maximum al-
lowable speed for each position is
given below for your reference:
ª2º 131 km/h (81 mph). . . . . . . . . . .
ªLº 72 km/h (44 mph). . . . . . . . . . .
Do not continue hill climbing or
hard towing for a long time in the
ª2º or ªLº position. This may cause
severe automatic transmission dam-
age from overheating. To prevent
such damage, ªDº position should
be used in hill climbing or hard
towing.
(e) Backing up
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with
your foot, shift the selector lever to the
ªRº position.
NOTICE
Never shift into reverse while the ve-
hicle is moving.

For ways to decrease the vehicle speed,
see ªCruise controlº in this section.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin or
skid.
(e) Using ª2º and ªLº positions
The ª2º and ªLº positions are used for
strong engine braking as described pre-
viously.
With the selector lever in ª2º or ªLº, you
can start the vehicle in motion as with the
lever in ªDº.
With the selector lever in ª2º, the vehicle
will start in first gear and automatically
shift to second gear.
With the selector lever in ªLº, the trans-
mission is engaged in first gear.
NOTICE
Be careful not to over±rev the en-
gine. Watch the tachometer to keep
engine rpm from going into the red
zone. The approximate maximum al-
lowable speed for each position is
given below for your reference:
ª2º 123 km/h (76 mph). . . . . . . . . . . .
ªLº 67 km/h (42 mph). . . . . . . . . . . .
Do not continue hill climbing or
hard towing for a long time in the
ª2º or ªLº position. This may cause
severe automatic transmission dam-
age from overheating. To prevent
such damage, ªDº position should
be used in hill climbing or hard
towing.
(f) Backing up
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with
your foot, shift the selector lever to the
ªRº position.
NOTICE
Never shift into reverse while the ve-
hicle is moving.
(g) Parking
1. Bring the vehicle to a complete stop.
2. Pull the parking brake lever up fully to
securely apply the parking brake.
3. With the brake pedal pressed down,
shift the selector lever to the ªPº posi-
tion.
CAUTION
Never attempt to move the selector
lever into ªPº position under any cir-
cumstances while the vehicle is mov-
ing. Serious mechanical damage and
loss of vehicle control may result.
(h) Good driving practice
If the transmission repeatedly shifts up
and down between third gear and over-
drive when climbing a gentle slope, the
overdrive should be turned off. Be sure
to turn the switch on immediately after-
ward.
When towing a trailer, in order to main-
tain engine braking efficiency, do not
use overdrive.
