2-1. Driving procedures
Driving the vehicle
The following procedures should be observed to ensure safe driv-
ing.
■ Starting the engine ( P. 178)
■ Driving
With the brake pedal depressed, shift the shift lever to D. ( P. 181)
Release the parking brake. ( P. 187)
Gradually release the brake pedal and gently depress the
accelerator pedal to accelerate the vehicle.
■ Stopping
With the shift lever in D, depress the brake pedal.
If necessary, set the parking brake.
When the vehicle is stopped for an extended period of time, shift
the shift lever to P or N. ( P. 181)
■Parking the vehicle
With the shift lever in D, depress the brake pedal.
Set the parking brake. ( P. 187)
Shift the shift lever to P. ( P. 181)
When parking on a hill, if necessary, block the wheels.
Turn the engine switch off to stop the engine.
Lock the door, making sure that you have the key on your
person.

170 2-1. Driving procedures
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability
of the correct fuel. ( P. 671)
■ When turning off the engine
In cold climates, or following repeated short trips, emission system operating
sounds may continue for a short time after the engine is turned off. This is
not a malfunction, and helps to ensure optimal performance of the emission
system.
CAUTION
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the engine run-
ning. This prevents the vehicle from creeping.
■ When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accel-
erator pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake
pedal will result in sudden acceleration that may lead to an accident
that could result in death or serious injury.
• When backing up, you may twist your body around, leading to a diffi- culty in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle only slightly, allowing you to depress the brake and accelerator
pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using your left foot may delay response in an emergency, result-
ing in an accident.
● Do not drive the vehicle over or st op the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. This may
cause a fire if there is any flammable material nearby.
● Do not let the vehicle roll backwards while the shift lever is in a driving
position, or roll forward while the shift lever is in R.
Doing so may cause the engine to stall or lead to poor brake and steering
performance, resulting in an accident or damage to the vehicle.

When driving
CAUTION
■
When driving the vehicle
●If the smell of exhaust is noticed inside the vehicle, open the windows and
check that the back window is closed. Large amounts of exhaust in the
vehicle can cause driver drowsiness and an accident, resulting in death or
a serious health hazard. Have the vehicle inspected by your Toyota dealer
immediately.
● Do not shift the shift lever to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle\
control.
● Do not shift the shift lever to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle\
control.
● Do not shift the shift lever to D while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle\
control.
● Moving the shift lever to N while the vehicle is moving will disengage the
engine from the transmission. Engine braking is not available when 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 control, but the
power assist to these systems will be lost. This will make it more difficult to
steer and brake, so you should pull over and stop the vehicle as soon as it
is safe to do so.
However, in the event of an emergency, such as if it becomes impossible
to stop the vehicle in the normal way: P. 655
● Use engine braking (downshift) to maintain a safe speed when driving
down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. ( P. 181)
● When stopped on an inclined surface, use the brake pedal and parking
brake to prevent the vehicle from rolling backward or forward and causing
an accident.
