To reset the hour: Push the “H” button.
To reset the minutes: Push the “M” button.
Vehicles with cruise information only—
For quicker adjustment of the clock, hold
down “M” or “H” button continuously. This
allows faster advancement of the minutes
and hours while setting.
The engine switch must be in the “ACC”
or “ON” position.
If the electrical power source has been
disconnected from the clock, the time dis-
play will automatically be set to 1:00 (one
o’clock).
When the instrument panel lights are
turned on, the brightness of the time indi-
cation will be reduced.
Intuitive parking assist
XS10061a
1: Rear sensors
2: Rear corner sensors
3: Front corner sensors
The intuitive parking assist is designed
to inform you of the approximate dis-
tance between your vehicle and an ob-
struction by indicator and buzzer when
parking the vehicle. This system uses
sensors to detect obstructions.
This system works when the engine
switch is in the “ON” position and the
transmission is not in the “P” position.
Rear and rear corner sensors work only
when the transmission is in the “R” posi-
tion.
Front corner sensors works when:
Transmission is in the “R” position.
Transmission is not in the “P” or “R”
position and vehicle speed is approxi-
mate 10 km/h (6 mph) or less.

Perceptible area
A: Approximately 1800 mm (70.9 in.)
B: Approximately 850 mm (33.5 in.)
C: Approximately 600 mm (23.6 in.)
Perceptible area is limited as shown in
the previous illustration. Check the area
around the vehicle before driving and start
driving slowly.
The maximum detection distance of the
sensor varies depending on the size of
the obstacle, the sensor can detect a
large obstacle such as a wall, up to 1800
mm (70.9 in.) away. However, the detec-
tion distance of a thin obstacle such as a
pole is less than 1800 mm (70.9 in.).CAUTION
The intuitive parking assist is in-
tended as an aid to assist you to
park and is not a substitute for
your personal judgment. Make your
driving decisions based on your ob-
servations.
Do not attach accessories or other
objects to the vehicle within the
sensor perceptible area. Doing so
may cause the system to malfunc-
tion, which might result in an acci-
dent.
In certain situations, the system
will not function properly and when
the vehicle approaches certain ob-
jects, the system will not detect
those objects. Therefore, always ob-
serve the area around the vehicle
and do not rely solely on the sys-
tem.

Long reach
type
Your engine is fitted with long reach
iridiumtipped spark plugs.
NOTICE
Use only iridiumtipped spark plugs.
Do not adjust gaps for engine perfor-
mance smooth driveability.
For details about the spark plug type, see
“Service specifications” on page 589 in
Section 8. The tandem master cylinder brake system
is a hydraulic system with two separate
sub
−systems. If either sub −system s hould
fail, the other will still work. However, the
pedal will be harder to press, and your
stopping distance will increase. Also, the
brake system warning light may come on.
CAUTION
Do not drive your vehicle with only 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 reserved
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 reserved vacu-
um.
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hard, much harder than nor-
mal. And your braking distance will
increase.

If either of the following conditions oc-
curs, this indicates a malfunction some-
where in the components monitored by
the warning light system. Contact your
Toyota dealer as soon as possible to
service the vehicle.
The light does not come on when the
engine switch is turned to the “ON”
position, or remains on.
The light comes on while you are dri-
ving.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the “ABS” warning light remains on
together with the brake system warn-
ing light, immediately stop your ve-
hicle at a safe place and contact your
Toyota dealer.
In this case, not only the antilock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
DRUMINDISC TYPE PARKING BRAKE
SYSTEM
Your vehicle has a drum −in −disc type
parking brake system. This type of brake
system n eeds burnishing of the brake
shoes periodically or whenever the parking
brake shoes and/or drums are replaced.
Have your Toyota dealer perform the bur-
nishing. BRAKE ASSIST SYSTEM
When you slam the brakes on, the
brake assist system judges as an emer-
gency stop and provides more powerful
braking for a driver who cannot hold
down the brake pedal firmly.
When you slam the brakes on, more pow-
erful braking will be applied. At this time,
you may hear a sound in the engine
compartment and feel the vibrations of the
brake pedal. This does not indicate a mal-
function.
The brake assist system becomes opera-
tive after the vehicle has accelerated to
a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph).
For an explanation of this system’s warn-
ing light, see “Service reminder indicators
and warning buzzers” on page 197 in Sec-
tion 1
−6.

Washing your vehicle or driving through
deep water may get the brakes wet. To
see whether they are wet, check that
there is no traffic near you, and then
press the pedal lightly. If you do not
feel a normal braking force, the brakes
are probably wet. To dry them, drive
the vehicle cautiously while lightly
pressing the brake pedal with the park-
ing brake applied. If they still do not
work safely, pull to the side of the road
and call a Toyota dealer for assistance.
Four−wheel drive models—Toyota rec-
ommends not using four −wheel drive on
dry hard− surfaced roads, because four −
wheel driving will cause unnecessary
noise and wear, and poor fuel econo-
my.
Four −wheel drive models—In cold tem-
peratures, noise may occur when driv-
ing in two −wheel drive before the trans-
fer is warmed up. Therefore, first drive
in four −wheel drive until the transfer is
warmed up.
CAUTION
Before driving off, make sure that
the parking brake is fully released
and the brake system warning light
(parking brake reminder light) is
off.
Do not leave your vehicle unat-
tended while the engine is running.
Do not rest your foot on the brake
pedal while driving. It can cause
dangerous overheating, needless
wear, and poor fuel economy.
To drive down a long or steep hill,
reduce your speed and downshift.
Remember, if you ride the brakes
excessively, they may overheat and
not work properly.
Be careful when accelerating, up-
shifting, downshifting or braking on
a slippery surface. Sudden accelera-
tion or engine braking, could cause
the vehicle to skid or spin.
Do not drive in excess of the speed
limit. Even if the legal speed limit
permits it, do not drive over 140
km/h (85 mph) unless your vehicle
has highspeed capability tires.
Driving over 140 km/h (85 mph) may
result in tire failure, loss of control
and possible injury. Be sure to con-
sult a tire dealer to determine
whether the tires on your vehicle
are highspeed capability tires or
not before driving at such speeds.
Do not continue normal driving
when the brakes are wet. If they are
wet, your vehicle will require a
longer stopping distance, and it
may pull to one side when the
brakes are applied. Also, the park-
ing brake will not hold the vehicle
securely.

If your engine stalls while driving...
1. Reduce your speed gradually, keeping a straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3. Turn the engine switch to the “ACC” or “LOCK” position, and try starting the
engine again.
If the engine will not start, see “If your
vehicle will not start” on page 498 in this
Section.
CAUTION
If the engine is not running, the pow-
er assist for the brakes and steering
will not work so steering and braking
will be much harder than usual.
If engine speed does not increase when
the accelerator pedal is depressed, there
may be a problem somewhere in the elec-
tronic throttle control system.
At this time, vibration may occur. Howev-
er, if you depress the accelerator pedal
more firmly and slowly, you can drive your
vehicle at low speeds. Have your vehicle
checked by your Toyota dealer as soon as
possible.
Even if the abnormality of the electronic
throttle control system is corrected during
low speed driving, the system may not be
recovered until the engine is stopped and
the engine switch is turned to the “ACC”
or “LOCK” position.
CAUTION
Be especially careful to prevent erro-
neous pedal operation.
If your engine coolant temperature
gauge indicates overheating, if you ex-
perience a loss of power, or if you hear
a loud knocking or pinging noise, the
engine has probably overheated. You
should follow this procedure... 1. Pull safely off the road, stop the ve- hicle and turn on your emergency
flashers. Put the transmission in “P”
and apply the parking brake. Turn off
the air conditioning if it is being used.
2. If coolant or steam is boiling out of the radiator or reservoir, stop the engine.
Wait until the steam subsides before
opening the hood. If there is no coolant
boiling over or steam, leave the engine
running.
CAUTION
To help avoid personal injury, keep
the hood closed until there is no
steam. Escaping steam or coolant is
a sign of very high pressure.

driving If you cannot incr
ease engine

If towing is necessary, we recommend
you to have it done by your Toyota
dealer or a commercial tow truck ser-
vice.
If towing service is not available in an
emergency, your vehicle may be tempo-
rarily towed by a cable or chain se-
cured to one of the emergency towing
eyelet under the front of the vehicle.
Use extreme caution when towing the
vehicle.
NOTICE
Only use specified towing eyelet;
otherwise your vehicle may be dam-
aged.
A driver must be in the vehicle to steer
it and operate the brakes.
Towing in this manner may be done only
on hard−surfaced roads for a short dis-
tance and at low speeds. Also, the
wheels, axles, drive train, steering and
brakes must all be in good condition.
CAUTION
Use extreme caution when towing the
vehicle. Avoid sudden starts or errat-
ic driving maneuvers which would
place excessive stress on the emer-
gency towing eyelet and towing cable
or chain. The eyelet and towing cable
or chain may break and cause serious
injury or damage.
NOTICE
Use only a cable or chain specifically
intended for use in towing vehicles.
Securely fasten the cable or chain to
the towing eyelet provided.
Before towing, release the parking brake
and put the transmission in “N”. The
engine switch must be in the “ACC”
(engine off) or “ON” (engine running)
position.
Four −wheel drive models—Put the front
drive control switch knob in “2WD”.
CAUTION
If the engine is not running, the pow-
er assist for the brakes and steering
will not work so steering and braking
will be much harder than usual.
