■Turning the key from “ACC” to “LOCK”
Shift the shift lever to P (automatic transmission) or N (manua l transmis-
sion).
■ If the engine does not start (vehicles with engine immobilizer system)
The engine immobilizer system may not have been deactivated. ( P. 69)
Contact your Toyota dealer.
■ When the steering lock cannot be released
■ Key reminder function
A buzzer sounds if the driver’s door is opened while the engine switch is in
the “ACC” or “LOCK” position to remind you to remove the key. Push in the key and turn it to the

Vehicles without a smart key system:While the engine switch is in the “ON” position, move the shiftlever with the brake pedal depressed.
When shifting the shift lever between P and D, make sure that t he vehi-
cle is completely stopped.

Shifting the shift lever

2064-2. Driving procedures
Press the shift lock override
button.
The shift lever can be shifted while
the button is pressed.
■ If the “S” indicator does not come on even after shifting the shift lever to S
This may indicate a malfunction in the automatic transmission system. Have
the vehicle inspected by your Toyota dealer, immediately.
■ Downshifting restrictions warning buzzer (S mode)
To help ensure safety and driving performance, downshifting ope ration may
sometimes be restricted. In some circumstances, downshifting may not be
possible even when the shift lever is operated. (A buzzer will sound twice.)
■ Transmission protection function
If the tires spin continually when the vehicle becomes stuck in mud, dirt or
snow, or if the accelerator pedal is depressed and released repeatedly while
driving, the automatic transmission temperature may become too high and
the automatic transmission may be damaged.
To avoid damaging the automatic transmission, the system may temporarily
lock the gear.
If the automatic transmission temperature falls, the gear locking is canceled
and the automatic transmission is returned to the normal operation.

WARNING
■ When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.
■ To prevent an accident when releasing the shift lock
Before pressing the shift lock override button, make sure to se t the parking
brake and depress the brake pedal.
If the accelerator pedal is accidentally depressed instead of t he brake pedal
when the shift lock override button is pressed and the shift lever is shifted
out of P, the vehicle may suddenly start, possibly leading to an accident
resulting in death or serious injury.

Driving
Pulling the lever toward you
cancels the speed control.
Vehicle-to-vehicle distance control
mode: The speed control is also
canceled when the brake pedal is
depressed.
Constant speed control mode: The
speed setting is also canceled
when the brakes are applied or the
clutch pedal (manual transmission
only) is depressed.
Pushing the lever up resumes the cruise control and returns veh icle
speed to the set speed.
However, cruise control does not resume when the vehicle speed is
approximately 25 mph (40 km/h) or less.
When your vehicle is too close to
a vehicle ahead, and sufficient
automatic deceleration via the
cruise control is not possible, the
display will flash and the buzzer
will sound to alert the driver. An
example of this would be if
another driver cuts in front of you
while you are following a vehicle.
Depress the brake pedal to
ensure an appropriate vehicle-to-
vehicle distance.
■Warnings may not occur when
In the following instances, war nings may not occur even when th e
vehicle-to-vehicle distance is small.
● When the speed of the preceding vehicle matches or exceeds
your vehicle speed
● When the preceding vehicle is traveling at an extremely slow
speed
● Immediately after the cruise control speed was set
● When depressing the accelerator pedal

■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.

■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 above approximately 25 mph (40 km/h).
■ Accelerating after setting the vehicle speed
●The vehicle can be accelerated normally. After acceleration, th e set speed
resumes.
● Even without canceling the cruise control, the set speed can be increased
by first accelerating the vehicle to the desired speed and then pushing the
lever down to set the new speed.
■ Automatic cruise control cancellation
Cruise control will stop maintaining the vehicle speed in any o f the following
situations.
● Actual vehicle speed falls more than approximately 10 mph (16 k m/h) below
the preset vehicle speed.
At this time, the memorized set speed is not retained.
● Actual vehicle speed is below approximately 25 mph (40 km/h).
● VSC is activated.
● TRAC is activated for a period a time.
● When the VSC or TRAC system is turned off.
● 4WD models: The operation cannot be switched for 5 seconds or m ore after
operating the front-wheel drive control switch.
■ If “Cruise Control Malfunction Vi sit Your Dealer” is displayed on the
multi-information display
Press the “ON-OFF” button once to deactivate the system, and th en press
the button again to reactivate the system.
If the cruise control speed cannot be set or if the cruise cont rol cancels imme-
diately after being activated, there may be a malfunction in th e cruise control
system. Have the vehicle inspected by your Toyota dealer.

●Shifting to “4H” or “4L”
Automatic transmission
If the “4LO” indicator continues to blink when you operate the front-wheel
drive control switch to the “4H” or “4L” position, drive forwar d or backward
in a short distance, then stop the vehicle completely, shift th e shift lever
securely to N and operate the switch again.
Manual transmission
If the “4LO” indicator continues to blink when you operate the front-wheel
drive control switch to the “4H” or “4L” position, drive forwar d or backward
in a short distance, then stop the vehicle completely, depress the clutch
pedal and operate the switch again.
If the indicator light continues to blink even if doing so, contact your Toyota
dealer as soon as possible. There may be a trouble in the four- wheel drive
system.
■ Shifting to “4L”
VSC is automatically turned off.
■ Four-wheel drive usage frequency
You should drive in four-wheel drive for at least 10 miles (16 km) each month.
This will assure that the front drive components are lubricated.
WARNING
■Caution while driving
● Never shift the front-wheel drive control switch from “2WD” to “4H” if the
wheels are slipping.
Stop the slipping or spinning before shifting.
● For normal driving on dry and hard surface roads, use “2WD” pos ition.
Driving on dry and hard surface roads in “4H” or “4L” position may cause
drive component oil leakage, seizure, or other problems resulti ng in an
accident. Further, it may cause tire wear and increased fuel consumption.
● Avoid turning suddenly in “4H” or “4L” position. If you do turn suddenly, the
difference in turning speeds between the front and rear wheels may have
a similar effect to braking, thus making driving difficult.
● Do not shift the front-wheel drive control switch when the vehicle is turning
or when its wheels are spinning freely off the ground.

this has no effect, additionally use the rear differential lock system.
Be sure to stop the wheels.
Press the rear differential lock switch.
After the rear differential is locked, the indicator will come on.
Gently depress the accelerator pedal.
Unlock the rear differential as soon as the vehicle moves.
