2-1. Driving procedures

When driving
PRIUS_U (OM47668U) U.S.A.
Starting on a steep incline
Firmly set the parking brake and shift the shift lever to “D”.
Gently depress the accelerator pedal.
Release the parking brake.
■Driving in the rain
● 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
especially 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, preventing the steering and brakes from operating properly.
■ Breaking in your new Toyota
To extend the life of the vehicle, the following precautions are recommended
to observe:
● For the first 200 miles (300 km):
Avoid sudden stops.
● For the first 600 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive at a constant speed for extended periods.

PRIUS_U (OM47668U) U.S.A.
CAUTION
●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.
● 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
that may result in death or serious injury.
● Always check that all passengers’ arms, heads or other parts of their bod-
ies are not outside the vehicle, as this may result in death or serious injury.
● Do not drive in excess of the speed limit. Even if the legal speed limit per-
mits it, do not drive over 85 mph (140 km/h) unless your vehicle has high-
speed capability tires. Driving over 85 mph (140 km/h) may result 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 capability
tires or not before driving at such speeds.
■ When driving on slippery road surfaces
● Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle, resulting in an accident.
● Sudden changes in engine speed, such as engine braking caused by up-
shifting or down-shifting, may 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 may 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
Be careful not to shift the shift lever with the accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may
cause an accident and result in death or serious injury.

CAUTION
■Situations unsuitable for the LKA system
Using the LKA system in any of the following situations may result in
improper operation of the system and could lead to an accident, causing
death or serious injury. Turn the LKA system off while driving in any of the
following situations.
● When it is difficult to see lane markings because they are dirty or not clear
● When it is difficult to see lane markings due to rain, snow, fog or glare
● When the headlights are not bright enough due to dirt on the lenses or if
the headlight aim is not adjusted appropriately
● When a lane marking is not present, such as before tollbooths on a free-
way
● When sudden changes in the light level occur repetitively
● When there are misleading lines such as shadows, lines of snow, wheel
ruts with rain collected in them, or lines that remain after road repairs
● When driving in lanes other than the driving lane or passing lane on free-
way or motor highways
● When there is a lane closure due to road repairs or when driving in a
makeshift lane
● When the lanes are narrow or wide
● When the distance from the vehicle ahead of you is short
● When the vehicle leans to one side an unusual amount due to a heavy
load or improper tire inflation pressure
● When driving on winding roads or on uneven roads
● When driving on slippery roads, such as those covered with rain, ice or \
snow
● The tires have been exchanged (including snow tires), or the suspension
has been modified

PRIUS_U (OM47668U) U.S.A.
CAUTION
■When the Enhanced VSC is activated
The slip indicator light flashes and a warning buzzer sounds. Always drive
carefully.
Reckless driving may cause an accident. Exercise particular care when the
indicator light flashes and a buzzer sounds.
■ Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total
load capacity. In addition, make sure that the tires are inflated to the speci-
fied tire pressure level.
The ABS and Enhanced VSC will not function correctly if different tires are
fitted on the vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.
■ Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause the system to malfunction.

Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropri-
ate to the prevailing weather conditions.
■ Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tem-
peratures.
• Engine oil
• Engine/power control unit coolant
• Washer fluid
● Have a service technician inspect the level and specific grav-
ity of 12 volt battery electrolyte.
● Have the vehicle fitted with four snow tires or purchase a set
of tire chains for the front tires.
Ensure that all tires are the same size and brand, and that chains
match the size of the tires.

Selecting tire chains
Vehicles with 17-inch tires
Use the correct tire chain size when mounting the tire chains.
Chain size is regulated for each tire size.
Side chain:
0.12 in. (3.0 mm)
1.18 in. (30.0 mm)
0.39 in. (10.0 mm)
Cross chain:
0.16 in. (4.0 mm)
0.98 in. (25.0 mm)
0.55 in. (14.0 mm)
Vehicles with 15-inch tires
Use the tire chains of correct size and type.
Use SAE Class “S” type radial tire chains except radial cable chains or V-
bar type chains.
