• Place the electronic key in a location 2
m (6 ft.) or more away from the vehi-
cle. (Take care to ensure that the key
is not stolen.)
• Set the electronic key to battery-sav-
ing mode to disable the smart entry &
start system. (→P.124)
●If the electronic key is inside the vehi-
cle and a door handle becomes wet
during a car wash, a message may be
shown on the multi-information dis-
play and a buzzer will sound outside
the vehicle. To turn off the alarm, lock
all the doors.
●The lock sensor may not work prop-
erly if it comes into contact with ice,
snow, mud, etc. Clean the lock sensor
and attempt to operate it again.
●A sudden handle operation or a han-
dle operation immediately after enter-
ing the effective range may prevent
the doors from being unlocked. Touch
the door unlock sensor and check that
the doors are unlocked before pulling
the door handle again.
●If there is another electronic key in the
detection area, it may take slightly lon-
ger to unlock the doors after the door
handle is gripped.

extended periods
●To prevent theft of the vehicle, do not
leave the electronic key within 2 m (6
ft.) of the vehicle.
●The smart entry & start system can be
deactivated in advance. (→P.422)
●Setting the electronic key to battery-
saving mode helps to reduce key bat-
tery depletion. (→P.124)
■To operate the system properly
Make sure to carry the electronic key
when operating the system. Do not get
the electronic key too close to the vehi-
cle when operating the system from the
outside of the vehicle.
Depending on the position and holding
condition of the electronic key, the key
may not be detected correctly and the system may not operate properly. (The
alarm may go off accidentally, or the
door lock prevention function may not
operate.)

■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 driv-
ing on an expressway in the rain,
because there may be a layer of water
between the tires and the road sur-
face, preventing the steering and
brakes from operating properly.
■Engine speed while driving (vehi-
cles with a Multidrive)
In the following conditions, the engine
speed may become high while driving.
This is due to automatic up-shifting con-
trol or down-shifting implementation to
meet driving conditions. It does not indi-
cate 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 power mode is selected
■Restraining the engine output
(Brake Override System)
●When the accelerator and brake ped-
als 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 [vehicles with a Multi-
drive])
●When the following unusual operation
is performed, the engine output 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 M) with the accelerator
pedal depressed, a warning message
appears on the multi-information dis-
play. If a warning message is shown
on the multi-information display, read
the message and follow the instruc-
tion.

4-1. Before driving
Driving
WARNING
●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.164, 168)
●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.
■When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and reduce your ability to control
the vehicle.
●Sudden acceleration, engine brak-
ing due to shifting, or changes in engine speed could cause the vehi-cle to skid.
●After driving through a puddle, lightly depress the brake pedal to
make sure that the brakes are func- tioning properly. Wet brake pads may prevent the brakes from func-
tioning properly. If the brakes on only one side are wet and not func-tioning properly, steering control
may be affected.
■When shifting the shift lever
●Vehicles with a Multidrive: Do not let the vehicle roll backward while a forward driving position is selected,
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 vehi-
cle.
●Vehicles with a Multidrive: Do not shift the shift lever to P while the vehicle is moving.
Doing so can damage the transmis- sion 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 transmis- sion and may result in a loss of vehicle control.
●Do not shift the shift lever to a driv-ing position while the vehicle is
moving backward. Doing so can damage the transmis-sion 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.
●Vehicles with a Multidrive: Be care-
ful not to shift the shift lever with the accelerator pedal depressed. Shift-ing the shift lever to any positions
other than P or N may lead to unex- pected rapid acceleration of the vehicle that may cause an accident
and result in death or serious injury.
■If you hear a squealing or scrap-
ing noise (brake pad wear indica- tors)
Have the brake pads checked and
replaced by any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer as soon as
possible.
Rotor damage may result if the pads
are not replaced when needed.
It is dangerous to drive the vehicle
when the wear limits of the brake pads and/or those of the brake discs are exceeded.

4-1. Before driving
NOTICE
• Do not use the clutch pedal to adjust vehicle speed. When stop-
ping the vehicle with the shift lever in a position other then N, make sure to fully depress the clutch
pedal and stop the vehicle using the brake.Doing so may damage the clutch.
• When stopping the vehicle with the shift lever in a position other than N,
make sure to fully depress the clutch pedal and stop the vehicle using the brakes.
●Do not shift the shift lever to R with-out the vehicle completely stopped.
Doing so may damage the clutch, transmission and gears.
■When parking the vehicle (vehi-cles with a Multidrive)
Always set the parking brake and shift
the shift lever to P. Failure to do so may cause the vehicle to move or the vehicle may accelerate suddenly if
the accelerator pedal is accidentally depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold 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 possible to
avoid damaging the wheels, under- side of the vehicle, etc.
■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.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.
Information on what to do in case of a
flat tire ( →P.379, 389)
■When encountering flooded
roads
Do not drive on a road that has flooded after heavy rain, etc. Doing so
may cause the following serious dam- age to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle becomes flooded or stuck in mud or
sand, be sure to have any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer check
the following:
●Brake function
●Changes in the quantity and quality of the engine oil, transmission fluid,
clutch fluid, differential oil, etc.
●Lubricant condition for the bearings
and suspension joints (where possi- ble), and the function of all joints, bearings, etc.
