■When starting off on an uphill
Hill-start assist control is activated. (
P. 322)
■ 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 driving at high speeds in the rain, as there may b e a layer of
water between the tires and the road surface, preventing the st eering and
brakes from operating properly.
■ Engine speed while driving
In the following conditions, the engine speed may become high while 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 S 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.
■ 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 Control so that the vehicle may b ecome able to
escape from the mud or fresh snow.

Before towing
Check that the following conditions are met:
●Ensure that your vehicle’s tires are properly inflated. ( P. 529)
● Trailer tires are inflated according to the trailer manufacture r’s recommen-
dation.
● All trailer lights work as required by law.
● All lights work each time you connect them.
● The trailer ball is set at the proper height for the coupler on the trailer.
● The trailer is level when it is hitched.
Do not drive if the trailer is not level, and check for imprope r tongue weight,
overloading, worn suspension, or other possible causes.
● The trailer cargo is securely loaded.
● The rear view mirrors conform to all applicable federal, state/provincial or
local regulations. If they do not, install rear view mirrors ap propriate for tow-
ing purposes.
● Depress “TOW/HAUL” button (if equipped)
■ AVS (adaptive variable suspension system) (if equipped)
The suspension can be switched for improvement in drivability. (P. 314)
■ Break-in schedule
If your vehicle is new or equipped with any new power train com ponents
(such as an engine, transmission, differential or wheel bearing ), Toyota rec-
ommends that you do not tow a trailer until the vehicle has bee n driven for
over 500 miles (800 km).
After the vehicle has been driven for over 500 miles (800 km), you can start
towing. However, for the next 500 miles (800 km), drive the veh icle at a speed
of less than 50 mph (80 km/h) when towing a trailer, and avoid full throttle
acceleration.
■ Maintenance
●If you tow a trailer, your vehicle will require more frequent m aintenance due
to the additional load. (See “Scheduled Maintenance Guide” or “ Owner’s
Manual Supplement”.)
● Retighten the fixing bolts of the towing ball and bracket after approximately
600 miles (1000 km) of trailer towing.

■Dynamic radar cruise control can be set when
●The shift lever is in D or range 4 or higher of S has been sele cted.
● 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 mode
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.
● The operation cannot be switched for 5 seconds or more after operating the
four-wheel drive control or the center differential lock switch . (4WD models)
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.

the set vehicle speed.
● Actual vehicle speed falls 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.
● Pre-collision braking is activated.
● The operation cannot be switched for 5 seconds or more after operating the
four-wheel drive control or the center differential lock switch . (4WD models)
If constant speed control mode is automatically canceled for an y other rea-
son, there may be a malfunction in the system. Contact your Toyota dealer.
■ Brake system operation sound
If the brakes are applied automatically while the vehicle is in vehicle-to-vehi-
cle distance control mode, a brake system operation sound may b e heard.
This does not indicate a malfunction.
■ Warning messages and buzzers for d ynamic radar cruise control
Warning messages and buzzers are used to indicate a system malfunction or
to inform the driver of the need for caution while driving. If a warning message
is shown on the multi-information display, read the message and follow the
instructions.
■ When the sensor may not be correctly detect ing the vehicle ahead
In the case of the following and depending on the conditions, o perate the
brake pedal when deceleration of the system is insufficient or operate the
accelerator pedal when acceleration is required.
As the sensor may not be able to correctly detect these types o f vehicles, the
approach warning ( P. 284) may not be activated.
● Vehicles that cut in suddenly

■Shifting between “2WD” and “4H”
●When the ambient temperature is 5.0 °F (-15 °C) or lower, shifting from
“2WD” to “4H” cannot be performed with the vehicle speed above 43 mph
(70 km/h).
● If the “4HI” indicator does not go off when you shift from “4H” to “2WD”, drive
straight ahead while accelerating or decelerating, or drive in reverse.
■ Front-wheel drive usage frequency
You should drive in front-wheel drive for at least 10 miles (16 km) each
month.
This will assure that the front drive components are lubricated .
■ The center differential lock switch can be operated when
●The front-wheel drive control switch is in the “4H” or “4L” pos ition.
● The vehicle speed is less than 62 mph (100 km/h)
■ Center differential lock system
●When the front-wheel drive control switch is in the “4L” positi on and the cen-
ter differential is locked, the VSC is automatically turned off .
● When the front-wheel drive control switch is turned to the “2WD ” position,
the center differential is automatically unlocked.
● If the operation is not completed, the center differential lock indicator blinks.
If the indicator does not go off when unlocking the center diff erential, drive
straight ahead while accelerating or decelerating, or drive in reverse.

If the “4LO” indicator, “4HI” indicator or the center different ial lock indi-
cator blinks
● If the “4LO” indicator continues to blink when shifting between “4H” and “4L”,
stop the vehicle completely, move the shift lever to N and oper ate the switch
again.
● If the shift lever is moved before the “4LO” indicator turns on /off, the transfer
mode may not be shifted completely. The transfer mode disengage s both
the front and rear driveshafts from the powertrain and allows the vehicle to
move regardless of the shift position. (At this time, the indic ator blinks and
the buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic tr ansmission is in
P. You or someone else could be seriously injured. You must complete the
shifting of the transfer mode.
To complete the shifting, stop the vehicle completely, return t he shift lever to
N, and confirm that the shift was completed (The indicator turn s on/off).
● If the engine coolant temperature is too low, transfer mode may not be able
to shift. When the engine is warmer, turn the switch again.
If the “4LO” indicator, “4HI” i ndicator or the center different ial lock indicator
continues to blink even after attempting the above, there may b e a malfunc-
tion in the engine, the brake system or the four-wheel drive sy stem. In this
case, you may not be able to shift between “2WD” and “4H”, “4H” and “4L”,
and the center differential lock may not be operable. Have the vehicle
inspected by your Toyota dealer immediately.
■ Shifting to the “4L” position
The VSC off indicator will come on.
If the center differential is locked, VSC is automatically turn ed off.
