Before starting the engine, be sure to
follow the instructions in “(a) Before
cranking”.
Normal starting procedure
The multiport fuel injection system/sequen-
tial multiport fuel injection system in your
engine automatically controls the proper
air−fuel mixture for starting. You can start
a cold or hot engine as follows:
With your foot off the accelerator pedal,
crank the engine by turning the engine
switch to the “START” position. Release it
when the engine starts.
Engine should be warmed up by driving,
not in idle. For warming up, drive with
smoothly turning engine until engine cool-
ant temperature is within normal range.
If the engine stalls...
Simply restart it, using the correct proce-
dure given in normal starting.
If the engine will not start...
See “If your vehicle will not start” on page
498 in Section 4.NOTICE
 Do not crank for more than 30 se-
conds at a time. This may overheat
the starter and wiring systems.
 Do not race a cold engine.
 If the engine becomes difficult to
start or stalls frequently, have the
engine checked immediately.
Always slow down in gusty crosswinds.
This will allow you much better control.
Drive slowly onto curbs and, if pos-
sible, at a right angle. Avoid driving
onto high, sharp− edged objects and
other road hazards. Failure to do so
can lead to severe tire damage such
as a tire burst.
Drive slowly when passing over bumps
or travelling on a bumpy road. Other-
wise, the impact could cause severe
damage to the tires and/or wheels.
When parking on a hill, turn the front
wheels until they touch the curb so
that the vehicle will not roll. Apply the
parking brake, and place the transmis-
sion in “P”. If necessary, block the
wheels.

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.

Driving in the rain
Driving on a slippery road surface
Drive carefully when it is raining, because
visibility will be reduced, the windows may
become fogged− up, and the road will be
slippery.
Drive carefully when it starts to rain,
because the road surface will be espe-
cially slippery.
Refrain from high speeds when driving
on an expressway in the rain, because
there may be a layer of water between
the tires and the road surface, prevent-
ing the steering and brakes from oper-
ating properly.
CAUTION
Sudden braking, acceleration and
steering when driving on a slippery
road surface may cause tire slip-
page and reduce your ability to
control the vehicle, resulting in an
accident.
Sudden changes in engine speed,
such as sudden engine braking,
may cause the vehicle to skid, re-
sulting in an accident.
After driving through a puddle,
lightly depress the brake pedal to
make sure that the brakes are func-
tioning properly. Wet brake pads
may prevent the brakes from func-
tioning properly. If the brakes on
only one side are wet and not func-
tioning properly, steering control
may be affected, resulting in an ac-
cident.
When encountering flooded roads
Do not drive on a road that has flooded
after heavy rain etc. Doing so may cause
serious damage to the vehicle.
NOTICE
Driving on a flooded road may cause
the engine to stall as well as cause
serious vehicle malfunctions such as
shorts in electrical components and
engine damage from water immersion.
In the event that you drive on a
flooded road and the vehicle is
flooded, be sure to have your Toyota
dealer check brake function, changes
in quantity and quality of oil and fluid
used for the engine, transmission,
transfer (4WD vehicles), differentials,
etc. and lubricant condition for the
propeller shaft, bearings and suspen-
sion joints (where possible) and the
function of all joints and bearings.

SERVICE CONNECTOR FOR TOWING
BRAKE CONTROLLER (with towing
package)
Your vehicle is equipped with a service
connector for the trailer brake controller
as shown.
Access the service connector.
1. Remove the scuff plate.
2. Remove the clip (screw type) and trim board.
Remove the connector cover from the ser-
vice connector before connecting the con-
nector.
Link the connector to the trailer brake
controller via the sub wire harness stored
in the glove box. The detailed explanation
of the sub wire harness circuit is packed
together with the sub wire harness.
Be sure to position the trailer brake con-
troller where it does not prevent the driver
from operating the pedal.
Toyota recommends that the sub wire har-
ness be stored in the glove box when it
is not in use. TIRES
Ensure that your vehicle’s tires are
properly inflated. See page 553 in Sec-
tion 7
−2 and page 594 in Section 8 for
instructions.
The trailer tires should be inflated to
the pressure recommended by the trail-
er manufacturer in respect to the gross
trailer weight.

Improving fuel economy is easy—just take
it easy. It will help make your vehicle last
longer, too. Here are some specific tips
on how to save money on both fuel and
repairs:
Keep your tires inflated at the cor-
rect pressure. Underinflation causes
tire wear and wastes fuel. See page
553 in Section 7 −2 for instructions.
Do not carry unneeded weight in
your vehicle. Excess weight puts a
heavier load on the engine, causing
greater fuel consumption.
Avoid lengthy warmup idling. Once
the engine is running smoothly, begin
driving—but gently. Remember, howev-
er, that on cold winter days this may
take a little longer.
Put the selector lever into the “D”
when engine braking is not required.
Driving with the selector lever in a
position other than “D” will reduce the
fuel economy (For details, see
“Automatic transmission” on page 211
in Section 1− 7.)
Accelerate slowly and smoothly.
Avoid jackrabbit starts. Get into high
gear as quickly as possible.
Avoid long engine idling. If you have
a long wait and you are not in traffic,
it is better to turn off the engine and
start again later.
Avoid engine lugging or overrev-
ving. Use a gear position suitable for
the road on which you are travelling.
Avoid continuous speeding up and
slowing down. Stop−and− go driving
wastes fuel.
Avoid unnecessary stopping and
braking. Maintain a steady pace. Try
to time the traffic signals so you only
need to stop as little as possible or
take advantage of through streets to
avoid traffic lights. Keep a proper dis-
tance from other vehicles to avoid sud-
den braking. This will also reduce wear
on your brakes.
Avoid heavy traffic or traffic jams
whenever possible.
Do not rest your foot on brake ped-
al. This causes premature wear, over-
heating and poor fuel economy.
Maintain a moderate speed on high-
ways. The faster you drive, the greater
the fuel consumption. By reducing your
speed, you will cut down on fuel con-
sumption.
Keep the front wheels in proper
alignment. Avoid hitting the curb and
slow down on rough roads. Improper
alignment not only causes faster tire
wear but also puts an extra load on
the engine, which, in turn, wastes fuel.
Keep the bottom of your vehicle free
from mud, etc. This not only lessens
weight but also helps prevent corrosion
Keep your vehicle tunedup and in
top shape. A dirty air cleaner,
improper valve clearance, dirty plugs,
dirty oil and grease,brakes not
adjusted, etc. all lower engine
performance and contribute to poor fuel
economy. For longer life of all parts
and lower operating costs, keep all
maintenance work on schedule, and if
you often drive under severe
conditions, see that your vehicle
receives more frequent maintenance.
(For scheduled maintenance
information, please refer to the
“Scheduled Maintenance Guide” or
“Owner ’s Manual Supplement”.)

To raise the vehicle, insert the jack
handle end with the extension into the
jack (it is a loose fit) and turn it clock-
wise with the handle. As the jack
touches the vehicle and begins to lift,
double −check that it is properly posi-
tioned.
CAUTION
Never get under the vehicle when
the vehicle is supported by the
jack alone.

7. Remove the wheel nuts and change tires.
Lift the flat tire straight off and put it
aside.
Roll the spare wheel into position and
align the holes in the wheel with the
bolts. Then lift up the wheel and get
at least the top bolt started through
its hole. Wiggle the tire and press it
back over the other bolts.

Before putting on wheels, remove any
corrosion on the mounting surfaces
with a wire brush or such. Installation
of wheels without good metal− to−met-
al contact at the mounting surface can
cause wheel nuts to loosen and
eventually cause a wheel to come off
while driving.
