2
Before Driving
Engine Exhaust (Carbon monoxide)
WARNING
■Do not drive your vehicle if you sm ell exhaust gas inside the vehicle
Engine exhaust gas is dangerous. This gas contains carbon monoxide
(CO), which is colorless, odorless, and poisonous. When inhaled, it can
cause loss of consciousness and death. If you smell exhaust gas inside the
vehicle, keep all windows fully open and contact your Toyota dealer immedi-
ately.
■ Do not run the engine when inside an enclosed area
Running the engine inside an enclosed area, such as a garage, is danger-
ous. Exhaust gas, which contains poisonous carbon monoxide, could easily
enter the cabin. Loss of consciousness or even death could occur.
■ Open the windows or adjust the heating or cooling system to draw
fresh air when idling the engine:
Exhaust gas is dangerous. When the vehicle is stopped with the windows
closed and the engine running for a long time even in an open area,
exhaust gas, which contains poisonous carbon monoxide, could enter the
cabin. Loss of consciousness or even death could occur.
■ Clear snow from undern eath and around your vehi cle, particularly the
tail pipe, before starting the engine:
Running the engine when a vehicle is stopped in deep snow is dangerous.
The exhaust pipe could be blocked by the snow, allowing exhaust gas to
enter the cabin. Because exhaust gas contains poisonous carbon monox-
ide, it could cause loss of consciousness or even death to occupants in the
cabin.

2-8. Driving Tips

Before Driving
Rocking the Vehicle
If you must rock the vehicle to free it from snow, sand or mud, depress
the accelerator slightly and slowly move the shift lever from 1 (D) to R.
WARNING
■Do not spin the wheels at more th an 35 mph (56 km/h), and do not
allow anyone to stand behind a wheel when pushing the vehicle
When the vehicle is stuck, spinning the wheels at high speed is dangerous.
The spinning tire could overheat and explode. This could cause serious
injuries.
NOTICE
Too much rocking may cause engine overheating, transaxle failure, and tire
damage.

3-3. Transaxle
■Passing
For extra power when passing another vehicle or climbing steep
grades, depress the accelerator fully. The transaxle will shift to a
lower gear, depending on vehicle speed.
Some models:
The accelerator pedal may initially feel heavy as it is being depressed,
then feel lighter as it is depressed further. This change in pedal force
aids the engine control system in determining how much the accelerator
pedal has been depressed for performing kickdown, and functions to
control whether or not kickdown should be performed.
■
Climbing steep grades from a stop
To climb a steep grade from a stopped position:
Depress the brake pedal.
Shift to D or M1, depending on the load weight and grade steep-
ness.
Release the brake pedal while gradually accelerating.
■Descending steep grades
When descending a steep grade, shift to lower gears, depending on
load weight and grade steepness. Descend slowly, using the
brakes only occasionally to pr event them from overheating.
Driving Tips
WARNING
■Do not let the vehicle move in a di rection opposite to the direction
selected by the selector lever
Do not let the vehicle move backward with the selector lever in a forward
position, or do not let the vehicle move forward with the selector lever in the
reverse position. Otherwise, the engine may stop, causing the loss of the
power brake and power steering functions , and make it difficult to control
the vehicle which could result in an accident.

3-4. Switches and Controls
Windshield Wipers and Washer
The ignition must be switched ON to use the wipers.
Because heavy ice and snow can jam the wiper blades, the wiper motor is
protected from motor breakdown, overheating and possible fire by a circuit
breaker. This mechanism will automatically stop operation of the blades, but
only for about 5 minutes.
If this happens, turn off the wiper switch and park off the right-of-way, and
remove the snow and ice.
After 5 minutes, turn on the switch and the blades should operate normally. If
they do not resume functioning, consult your Toyota dealer as soon as possi-
ble. Drive to the side of the road and park off the right-of-way. Wait until the
weather clears before trying to drive with the wipers inoperative.
WARNING
■Use only windshield washer fluid or plain water in the reservoir
Using radiator antifreeze as washer fluid is dangerous. If sprayed on the
windshield, it will dirty the windshield, affect your visibility, and could result
in an accident.
■ Only use windshield washer fluid mixed with anti-freeze protection in
freezing weather conditions
Using windshield washer fluid without anti-freeze protection in freezing
weather conditions is dangerous as it could freeze on the windshield and
block your vision which could cause an accident. In addition, make sure the
windshield is sufficiently warmed using the defroster before spraying the
washer fluid.
