158 2-1. Driving procedures
WARNING
●On vehicles with a manual transmission, do not release the clutch pedal
too quickly. Doing so may propel the vehicle forward, possibly causing an
accident.
● Moving the shift lever to N while the vehicle is moving will di sengage the
engine from the transmission. Engine braking is not available w hen N is
selected.
● During normal driving, do not turn off the engine. Turning the engine off
while driving will not cause loss of steering or braking contro l, but the
power assist to these systems will be lost. This will make it m ore difficult to
steer and brake, so you should pull over and stop the vehicle a s soon as it
is safe to do so.
However, in the event of an emergency, such as if it becomes im possible
to stop the vehicle in the normal way: P. 454
● Use engine braking (downshift) to maintain a safe speed when dr iving
down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. ( P. 179, 185)
● Do not adjust the position of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control that can cause accidents,
resulting in death or serious injury.
● Always check that all passengers' arms, heads or other parts of their body
are not outside the vehicle, as this may result in death or ser ious injury.
● Do not drive in excess of the speed limit. Even if the legal sp eed limit per-
mits it, do not drive over 85 mph (140 km/h) unless your vehicl e has high-
speed capability tires. Driving over 85 mph (140 km/h) may resu lt in tire
failure, loss of control and possible injury. Be sure to consult a tire dealer
to determine whether the tires on your vehicle are high-speed c apability
tires or not before driving at such speeds.

When driving
WARNING
■
When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippa ge and
reduce your ability to control the vehicle, resulting in an acc ident.
● Sudden acceleration, engine braking due to shifting, or changes in engine
speed could cause the vehicle to skid, resulting in an accident .
● After driving through a puddle, lightly depress the brake pedal to make
sure that the brakes are functioning properly. Wet brake pads m ay prevent
the brakes from functioning properly. If the brakes on only one side are wet
and not functioning properly, steering control may be affected, resulting in
an accident.
■ When shifting the shift lever
●On vehicles with an automatic transmission, be careful not to s hift the shift
lever with the accelerator pedal depressed. Shifting the shift lever to a
gear other than P or N may lead to unexpected rapid acceleratio n of the
vehicle that may cause an accident and result in death or serious injury.
● Do not place items in the shift lever's surrounding area. It may cause incor-
rect operation.
● If the shift boot is pulled out during cleaning, return it to i ts previous posi-
tion. If the shift boot is left pulled out, the shift lever may become difficult to
operate.
■ If you hear a squealing or scrap ing noise (brake pad wear limit indica-
tors)
Have your Toyota dealer check and replace the brake pads as soo n as pos-
sible.
Rotor damage may result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of th e brake pads
and/or those of the brake discs are exceeded.

160 2-1. Driving procedures
WARNING
■When the vehicle is stopped
●Do not race the engine.
If the vehicle is in any gear other than P (vehicles with an au tomatic trans-
mission only) or N, the vehicle may accelerate suddenly and une xpectedly,
causing an accident.
● Do not leave the vehicle with the engine running for a long tim e.
If such a situation cannot be avoided, park the vehicle in an open space
and check that exhaust fumes do not enter the vehicle interior.
● On vehicles with an automatic transmission, in order to prevent accidents
due to the vehicle rolling away, always keep depressing the brake pedal
while the engine is running, and apply the parking brake as nec essary.
● If the vehicle is stopped on an incline, in order to prevent ac cidents caused
by the vehicle rolling forward or backward, always depress the brake pedal
and securely apply the parking brake as needed.
● Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped m ay cause
the exhaust system to overheat, which could result in a fire if combustible
material is nearby.

162 2-1. Driving procedures
WARNING
■Exhaust gases
Exhaust gases include harmful carbon monoxide (CO), which is colorless
and odorless. Inhaling exhaust gases may lead to death or a ser ious health
hazard.
● If the vehicle is in a poorly ventilated area, stop the engine. In a closed
area, such as a garage, exhaust gases may collect and enter the vehicle.
This may lead to death or a serious health hazard.
● The exhaust system should be checked occasionally. If there is a hole or
crack caused by corrosion, damage to a joint or abnormal exhaus t noise,
be sure to have the vehicle inspected and repaired by your Toyota dealer.
Failure to do so may allow exhaust gases to enter the vehicle, resulting in
death or a serious health hazard.
■ When taking a nap in the vehicle
Always turn the engine off. Otherwise, you may accidentally move the shift
lever or depress the accelerator pedal, this could cause an acc ident or fire
due to engine overheating. Additionally, if the vehicle is park ed in a poorly
ventilated area, exhaust gases may collect and enter the vehicl e, leading to
death or a serious health hazard.

NOTICE
■Pre-driving check
Trapping small animals in the cooling fan and belts of the engi ne may result
in a malfunction. Check that no small animal enters the engine compartment
and under the vehicle before starting the engine.
■ When driving the vehicle
Vehicles with an automatic transmission
●Do not depress the accelerator and brake pedals at the same tim e during
driving, as this may r estrain driving torque.
● Do not use the accelerator pedal or depress the accelerator and brake
pedals at the same time to hold the vehicle on a hill.
Vehicles with a manual transmission
● Do not depress the accelerator and brake pedals at the same tim e during
driving, as this may r estrain driving torque.
● Do not shift gears unless the clutch pedal is fully depressed. After shifting,
do not release the clutch pedal abruptly. Doing so may damage t he clutch,
transmission and gears.
● Observe the following to prevent the clutch from being damaged.
• Do not rest your foot on the clutch pedal while driving.
Doing so may cause clutch trouble.
• Do not use any gear other than the 1st gear when starting off and mov-
ing forward.
Doing so may damage the clutch.
• Do not use the clutch to hold the vehicle when stopping on an uphill
grade.
Doing so may damage the clutch.
● Do not shift the shift lever to R when the vehicle is still moving. Doing so
may damage the clutch, transmission and gears.
● Do not release the clutch pedal too quickly. Doing so may damag e the
transmission.
■ When parking the vehicle (vehicl es with an automatic transmission)
Always shift the shift lever to P. Failure to do so may cause t he vehicle to

Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and ho ld it there for
an extended period of time.
Doing so may damage the power steering motor.
● When driving over bumps in the road, drive as slowly as possibl e to avoid
damaging the wheels, underside of the vehicle, etc.
● On vehicles with an automatic transmission, do not race the eng ine for
more than 5 seconds in any position except the N or P position when the
brake is applied or when chocks are used in the wheels. This may cause
the transmission fluid to overheat.
■ If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehicle.
● It may be difficult to control your vehicle.
