1997 TOYOTA CAMRY Engine control

77
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 lock re-
lease button depressed).
(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, the
transmission will not shift into overdrive
gear even with the overdrive switch on.
Never put your foot in 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 following
speed, and more powerful engine
braking will be obtained.
5S-FE engine 106 km/h (65 mph). .
1MZ-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.
5S-FE engine 46 km/h (28 mph). . . .
1MZ-FE engine 56 km/h (34 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 or
skid.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.

NOTICE
Be careful not to overrev the en-
gine. 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:
2º 125 km/h (77 mph). . . . . .
Lº 69 km/h (42 mph). . . . .
Do not continue hill climbing or
hard towing for a long time in the
2º or Lº position. This may
cause severe automatic transmis-
sion damage from overheating.
To prevent such damage, Dº
position should be used in hill
climbing or hard towing.
(d) 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
Rº position.
NOTICE
Never shift into reverse while the
vehicle is moving.
(e) 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 Pº posi-
tion.
While the vehicle is moving, never
attempt to move the selector lever
into Pº position under any circum-
stances. Serious mechanical dam-
age and loss of vehicle control may
result.CAUTION
!
(f) Good driving practice

If the transmission is repeatedly up-
shifted and downshifted between third
gear and overdrive when climbing a
gentle slope, the overdrive switch
should be turned off. Be sure to turn
the switch on immediately afterward.

When towing a trailer, in order to main-
tain engine braking efficiency, do not
use overdrive.
Always keep your foot on the brake
pedal while stopped with the engine
running. This prevents the vehicle
from creeping.CAUTION
!
NOTICE
Do not hold the vehicle on an
upgrade with the accelerator pedal.
It can cause the transmission to
overheat. Always use the brake
pedal or parking brake.
(g) Rocking your vehicle if stuck
If you rock your vehicle to make it
out when it becomes stuck in snow,
mud, sand, etc., first check that
there are no physical objects or
people around the vehicle. During
the rocking operation the vehicle
may suddenly move forward or
backward as it becomes unstuck,
causing injury or damage to nearby
people or objects.CAUTION

The cruise control allows you to cruise
the vehicle at a desired speed over 40
km/h (25 mph) even with your foot off
the accelerator pedal.
Your cruising speed can be maintained up
or down grades within the limits of engine
performance, although a slight speed
change may occur when driving up or
down the grades. On steeper hills, a
greater speed change will occur so it is
better to drive without the cruise control.

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

Avoid vehicle speed increases
when driving downhill. If the ve-
hicle speed is too fast in relation to
the cruise control set speed, can-
cel the cruise control then down-
shift the transmission to use en-
gine braking to slow down.CAUTION
!TURNING ON THE SYSTEM
To operate the cruise control, push the
CRUISE ON-OFFº switch. This turns the
system on. The indicator light in the instru-
ment panel shows that you can now set
the vehicle at a desired cruising speed.
Another push will turn the system com-
pletely off.
To avoid accidental cruise control
engagement, keep the CRUISE
ON-OFFº switch off when not using
the cruise control.CAUTION
!
SETTING AT A DESIRED SPEED
On vehicles with automatic transmission,
the transmission must be in Dº before
you set the cruise control speed.
Bring your vehicle to the desired speed,
push the lever down in the SET/COASTº
direction and release it. This sets the ve-
hicle at that speed. If the speed is not sat-
isfactory, tap it down for a slower speed.
Each tap changes the set speed by 1.6
km/h (1.0 mph). You can now take your
foot off the accelerator pedal.

82
If you need acceleration Ð for example,
when passingÐdepress the accelerator
pedal enough for the vehicle to exceed the
set speed. When you release it, the ve-
hicle will return to the speed set prior to the
acceleration.
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 overrev-
ing.CAUTION
!
CANCELLING THE PRESET SPEED
You can cancel the preset speed by:
a. Pulling the lever in the CANCELº di-
rection and releasing it.
b. Depressing the brake pedal.
c. Depressing the clutch pedal (manual
transmission).
If the vehicle speed falls below about 40
km/h (25 mph), the preset speed will auto-
matically cancel out.
If the vehicle speed drops 16 km/h (10
mph) below the preset speed, the preset
speed will also automatically cancel out.If the preset speed automatically cancels
out other than for the above cases have
your vehicle checked by your Toyota deal-
er at the earliest opportunity.
RESETTING AT A FASTER SPEED
Push the lever up in the RES/ACCº direc-
tion and hold it. Release the lever when
the desired speed is attained. While the
lever is held up, the vehicle will gradually
gain speed.
However, a faster way to reset is to accel-
erate the vehicle and then push the lever
down in the SET/COASTº direction.
RESETTING AT A SLOWER SPEED
Push the lever down in the SET/COASTº
direction and hold it. Release the lever
when the desired speed is attained. While
the lever is held down, the vehicle speed
will gradually decrease.
However, a faster way to reset is to de-
press the brake pedal and then push the
lever down in the SET/COASTº direction.
On vehicles with automatic transmission,
even if you turn off the overdrive switch
with the cruise control on, engine braking
will not be applied because the cruise con-
trol is not cancelled. To decrease the ve-
hicle speed, reset to a slower speed withthe cruise control lever or depress the
brake pedal. If you use the brake pedal,
cruise control is cancelled.
RESUMING THE PRESET SPEED
If the preset speed is cancelled by pulling
the control lever or by depressing the
brake pedal or clutch pedal, pushing the
lever up in the RES/ACCº direction will
restore the speed set prior to cancellation.
However, once the vehicle speed falls be-
low about 40 km/h (25 mph), the preset
speed will not be resumed.
CRUISE CONTROL FAILURE WARN-
ING
If the CRUISEº indicator light in the in-
strument cluster flashes when using the
cruise control, press the CRUISE ON-
OFFº button to turn the system off and
then press it again to turn it on.
If any of the following conditions then oc-
curs, there is some trouble in the cruise
control system.

AUTOMATIC TRACTION CONTROL
SYSTEM
The traction control system automati-
cally controls spinning of the front
wheels which may occur when accel-
erating on slippery road surfaces, thus
assisting driver control and driving
power to the front wheels. When you
turn the ignition switch on, the trac-
tion control system always turns on
automatically, and the slip indicator/
warning light will come on. the indica-
tor lights will go off after about 3 sec-
onds.
Leave the system on during ordinary
driving so that it can operate when
needed. When traction control is ap-
plied, the slip indicator light blinks.
You may hear a slight clicking noise in the
engine compartment when the engine is
started. This means that the traction con-
trol system is in the self-check mode.,
and does not indicate malfunction. When
the traction control system is operating,
you may feel vibration of your vehicle,
caused by operation of brakes. This indi-
cates the system is functioning properly.When getting the vehicle out of mud or
new snow, etc. the traction control system
will operate to prevent the wheels from
spinning. Even though the accelerator
pedal is fully depressed, the engine speed
will be restrained to a certain level.
MANUAL OPERATION
You can turn off the traction control
system by pushing the TRAC OFFº
switch. The TRAC OFFº indicator/
warning light will come on. Pushing
the TRAC OFFº switch a second time
turns on the traction control system
and the TRAC OFFº indicator/warn-
ing light will go off.

Your vehicle does not need an elaborate
break-in. But following a few simple tips
for the first 1600 km (1000 miles) can add
to the future economy and long life of your
vehicle:

Do not drive over 88 km/h (55 mph).

Run the engine at moderate speed be-
tween 2000 and 4000 rpm.

Avoid full-throttle starts.

Try to avoid hard stops during the first
300 km (200 miles).

Do not drive slowly with the manual
transmission in a high gear.

Do not drive for a long time at any
single speed, either fast or slow.

Do not tow a trailer during the first 800
km (500 miles)FUEL TYPE
Your new vehicle must use only un-
leaded gasoline.
To help prevent gas station mixups, your
Toyota has a new smaller fuel tank opening.
The special nozzle on pumps with unleaded
fuel will fit it, but the larger standard nozzle
on pumps with leaded gas will not.
Do not use leaded gasoline. Use of
leaded gasoline will cause the
three-way catalytic converter to
lose its effectiveness and the emis-
sion control system to function im-
properly. Also, this can increase
maintenance costs.
NOTICE
OCTANE NUMBER
5S-FE engine: Select Research Octane
Number 91 (Octane Rating 87) or higher.
1MZ-FE engine: Select Research Oc-
tane Number 91 (Octane Rating 87) or
higher. For improved vehicle perfor-
mance, the use of premium unleaded
gasoline with a research Octane Num-
ber of 96 (Octane Rating 91) or higer is
recommended.

If you plan to drive your Toyota in
another country...
First, comply with the vehicle registration
laws.
Second, confirm the availability of the
correct fuel (unleaded and minimum oc-
tane number).
Type A
Type BThe three-way catalytic converter is
an emission control device installed in
the exhaust system.
The purpose is to reduce pollutants in the
exhaust gas.
CAUTION!

Keep people and combustible ma-
terials away from the exhaust pipe
while the engine is running. The ex-
haust gas is very hot.

Do not drive, idle or park your ve-
hicle over anything that might
burn easily such as grass, leaves,
paper or rags.
Three-way catalytic converter Operation in foreign countries
ProCarManuals.com

132
A large amount of unburned gases
flowing into the three-way catalytic
converter may cause it to overheat
and create a fire hazard. To prevent
this and other damage, observe the
following precautions:
Use only unleaded gasoline.
Do not drive with an extremely low
fuel level; running out of fuel
could cause the engine to misfire,
creating an excessive load on the
three-way catalytic converter.
Do not allow the engine to run at
idle speed for more than 20 min-
utes.
Avoid racing the engine.
Do not push-start or pull-start
your vehicle.
Do not turn off the ignition while
the vehicle is moving.
NOTICEKeep your engine in good running
order. Malfunctions in the engine
electrical system, electronic igni-
tion system/distributor ignition
system or fuel systems could
cause an extremely high three-
way catalytic converter tempera-
ture.
If the engine becomes difficult to
start or stalls frequently, take your
vehicle in for a check-up as soon
as possible. Remember, your To-
yota dealer knows your vehicle
and its three-way catalytic con-
verter system best.
To ensure that the three-way cata-
lytic converter and the engine
emission control system operate
properly, your vehicle must re-
ceive the periodic inspections re-
quired by the Toyota Maintenance
Schedule. For scheduled mainte-
nance information, refer to the
separate Owner's Manual Sup-
plement/Maintenance Scheduleº.
CAUTION!

Avoid inhaling the engine ex-
haust. It contains carbon monox-
ide, which is a colorless and odor-
less gas. It can cause uncon-
sciousness or even death.

Make sure the exhaust system
has no holes or loose connec-
tions. The system should be
checked from time to time. If you
hit something, or notice a change
in the sound of the exhaust, have
the system checked immediately.

Do not run the engine in a garage
or enclosed area except for the
time needed to drive the vehicle in
or out. The exhaust gases cannot
escape, making this a paticularly
dangerous situation.

Do not remain for a long time in a
parked vehicle with the engine
running. If it is unavoidable, how-
ever, do so only in an unconfined
area and adjust the heating or
cooling system to force outside
air into the vehicle.
