*1: Vehicles with an automatic transmission.
*2: These lights turn on when the engine switch is turned to the “ON” position(vehicles without a smart key system) or IGNITION ON mode (vehi cles
with a smart key system) to indicate that a system check is being per-
formed. They will turn off after the engine is started, or after a few seconds.
There may be a malfunction in a system if the lights do not com e on, or if
the lights do not turn off. Have the vehicle inspected by your Toyota dealer
for details.

1704-1. Before driving
■When starting off on an uphill (v ehicles with the hill-start assist control
system)
The hill-start assist control will activate. ( P. 324)
■ 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 (vehic les with an automatic transmission)
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 power mode is selected
■ 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. ( P. 493)
■ Restraining sudden start (Drive-Start Control: vehicles with an automatic
transmission)
● 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 Control so that the vehicle may b ecome able to
escape from the mud or fresh snow.
• Deactivate TRAC ( P. 324)
• When the AUTO LSD system is turned on.
(P. 307)
• 4WD models: The four-wheel drive control switch is in “4L” pos ition.
(P. 303)

Driving
NOTICE
■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 vehi-
cle.
● 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. 511)
■ When encountering flooded roads or waterlogged roads
Do not drive on a road that has flooded after heavy rain, etc. Doing so may
cause the following serious damage to the vehicle:
● Engine stalling
● Short in electrical components
● Engine damage caused by water immersion
● Rubber or mechanical part damage or poor lubrication due to grease
being washed away, or grease becoming contaminated with mud or dirt
In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have your Toyota dealer check the following:
● Brake function
● Changes in quantity and quality of oil and fluid used for the engine, trans-
mission, transfer (4WD models) differentials, etc.
● Lubricant condition for the propeller shaft, clutch fork, beari ngs and sus-
pension joints (where possible), and the function of all joints, bearings, etc.

2764-5. Using the driving support systems
■Dynamic radar cruise control can be set when
●Vehicles with an automatic transmission: The shift lever is in D or range 4 or
higher of S has been selected.
● Vehicle speed is at or above approximately 30 mph (50 km/h).
■ Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After acceler-
ating, the set speed resumes. However, during vehicle-to-vehicl e distance
control mode, the vehicle speed may decrease below the set spee d in order
to maintain the distance to the preceding vehicle.
■ Automatic cancelation of vehicle-to-vehicle distance control mo de
Vehicle-to-vehicle distance control mode is automatically cance led in the fol-
lowing situations:
● Actual vehicle speed falls at or below approximately 25 mph (40 km/h).
● VSC is activated.
● TRAC is activated for a period of time.
● When the VSC or TRAC system is turned off.
● The sensor cannot detect correctly because it is covered in some way.
● Pre-collision braking is activated.
● 4WD models: The operation cannot be switched for 5 seconds or m ore after
operating the front-wheel drive control switch.
If vehicle-to-vehicle distance control mode is automatically ca nceled for any
other reason, there may be a malfunction in the system. Contact your Toyota
dealer.
