Driving
■Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the win-
dows 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 r ain,
because there may be a layer of water between the tires and the road sur-
face, preventing the steering and brakes from operating properl y.
■ Engine speed while driving
In the following conditions, the engine speed may become high w hile driving.
This is due to automatic up-shifting control or down-shifting implementation to
meet driving conditions. It does not indicate sudden acceleration.
● The vehicle is judged to be driving uphill or downhill
● When the accelerator pedal is released
● When the brake pedal is depressed while TOW/HAUL mode is select ed (if
equipped)
■ Restraining the engine out put (Brake Override System)
● When the accelerator and brake pedals are depressed at the same time, the
engine output may be restrained.
● A warning message is displayed on the multi-information display while the
system is operating.
■ Restraining sudden start (Drive-Start Control)
● When the following unusual operation is performed, the engine o utput may
be restrained.
• When the shift lever is shifted from R to D, D to R, N to R, P to D, or P to
R (D includes S) with the accelerator pedal depressed, a warnin g mes-
sage appears on the multi-information display.
• When the accelerator pedal is depressed too much while the veh icle is in
reverse.
●
While Drive-Start Control is being activated, your vehicle may have trouble
escaping from the mud or fresh snow. In such case, perform the following
actions to cancel Drive-Start Co ntrol so that the vehicle may become able to
escape from the mud or fresh snow.
•Deactivate TRAC (P. 303)
• When the AUTO LSD system is turned on. (P. 298)
• 4WD models: The four-wheel drive control switch is in “4L” pos ition.
(P. 295)

1624-1. Before driving
■Breaking in your new Toyota
To extend the life of the vehicle, observing the following prec autions is recom-
mended:
● For the first 200 miles (300 km):
Avoid sudden stops.
● For the first 500 miles (800 km):
Do not tow a trailer.
● For the first 1000 miles (1600 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low gears.
• Do not drive at a constant speed for extended periods.
■ Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of brake
system needs bedding-down of the brake shoes periodically or wh enever the
parking brake shoes and/or drum are replaced. Have your Toyota dealer per-
form the bedding down operation.
■ Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability
of the correct fuel. ( P. 609)
■ When turning off the engine
The 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.

Driving
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the engine
running. 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 b rake
pedal will result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to di fficulty
in operating the pedals. Make sure to operate the pedals proper ly.
• Make sure to keep a correct driving posture even when moving t he
vehicle only slightly. This allows you to depress the brake and accelera-
tor 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 stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. Thes e hot
parts may cause a fire if there is any flammable material nearby.
● 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. 539
● 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. 196)
● Do not adjust the positions 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.
● Always check that all passengers’ arms, heads or other parts of their body
are not outside the vehicle.

1644-1. Before driving
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving the vehicle
● 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 on slippery road surfaces
● Sudden braking, acceleration and steering may cause tire slippa ge and
reduce your ability to control the vehicle.
● Sudden acceleration, engine braking due to shifting, or changes in engine
speed could cause the vehicle to skid.
● 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.
■ When shifting the shift lever
● Do not let the vehicle roll backward while the shift lever is i n a driving posi-
tion, or roll forward while the shift lever is in R.
Doing so may cause the engine to stall or lead to poor brake an d steering
performance, resulting in an accident or damage to the vehicle.
● 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 o f 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 o f vehicle
control.
● Do not shift the shift lever to a driving position while the ve hicle is moving
backward.
Doing so can damage the transmission and may result in a loss o f 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 w hen N is
selected.
● Be careful not to shift the shift lever with the accelerator pe dal depressed.
Shifting the shift lever to a gear other than P or N may lead t o moving
unexpectedly of the vehicle that may cause an accident.
