entry and exit.
Turning the engine switch to ACC
or ON mode will return the steering
wheel to the original position.
■The steering wheel can be adjusted when (power adjustable type)
The engine switch is in ON.
■ Automatic adjustment of the stee ring position (power adjustable type)
A desired steering position can be entered to memory and recall ed automati-
cally by the driving position memory system. ( P. 152)
■ Power easy access system (vehicles with driving position memory )
The steering wheel and driver’s seat move in accordance with en gine switch
position and the driver’s seat belt condition. ( P. 152)
Auto tilt away (power-adjustable type)
WARNING
■Caution while driving

Doing so may cause the driver to mishandle the vehicle and caus e an acci-
dent, resulting in death or serious injury.
■ After adjusting the steering wheel (manually adjustable type)
Make sure that the steering wheel is securely locked.
Otherwise, the steering wheel may move suddenly, possibly causi ng an
accident and resulting in death or serious injury.

1703-4. Adjusting the steering wheel and mirrors
■Recommended mirror angle when to wing a trailer (vehicles with extend-
ing mirrors)
■ Mirror operating conditions (power-adjustable type)
The engine switch is in ACC or ON.
■ When the mirrors are fogged up ( vehicles with outside rear view mirror
defoggers)
Turn on the mirror defoggers to defog the mirrors. ( P. 342, 349)
■ Automatic adjustment of the mirr or angle (vehicles with driving position
memory)
A desired mirror face angle can be entered to memory and recall ed automati-
cally by the driving position memory. ( P. 152)
■ Auto anti-glare function (if equipped)
When the anti-glare inside rear view mirror is set to automatic mode, the out-
side rear view mirrors will activate in conjunction with the an ti-glare inside
rear view mirror to reduce reflected light. ( P. 165)
Power adjust the upper part of the mir-
ror until an appropriate view is obtained.
It is recommended that the outer 2/3 of
the upper mirror be filled with images
other than the vehicle and trailer.
Manually adjust the lower part of the
mirror until an appropriate view of the
towed object is obtained. It is recom-
mended that the outer 2/3 of the lower
mirror be filled with images other than
the trailer.

■Moon roof open reminder function
The buzzer sounds and a message is shown on the multi-informati on display
in the instrument cluster when the engine switch is turned off and the driver’s
door is opened with the moon roof open.
■ When the battery is disconnected
The moon roof must be initialized in order to ensure proper ope ration.
Push and hold the switch toward the “UP” (tilt up) side or “ ▼” (sliding
close) side.
After the moon roof will tilt up and down, release the switch.
To ensure the initialization is complete, make sure automatic opening and
closing functions work properly.
■ Customization that can be configured at Toyota dealer
Settings (e.g. linked door lock operation) can be changed.
(Customizable features: P. 564)

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. 323)
• When the AUTO LSD system is turned on. (P. 318)
• 4WD models: The four-wheel drive control switch is in “4L” pos ition.
(P. 315)

1864-1. 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. 551)
■ 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.

Cargo and luggage
Cargo capacity depends on the total weight of the occupants.
(Cargo capacity) = (Total load capacity)  (Total weight of occupants)
Steps for Determining Correct Load Limit —
(1) Locate the statement “The co mbined weight of occupants and
cargo should never exceed XXX kg or XXX lbs.” on your vehicle’s
placard.
(2) Determine the combined weight of the driver and passengers t hat
will be riding in your vehicle.
(3) Subtract the combined weight of the driver and passengers fr om
XXX kg or XXX lbs.
(4) The resulting figure equals the available amount of cargo an d lug-
gage load capacity.
For example, if the “XXX” amount equals 1400 lbs. and there wil l be
five 150 lb passengers in your vehicle, the amount of available
cargo and luggage load capacity is 650 lbs. (1400  750 (5150) =
650 lbs.)
(5) Determine the combined weight of luggage and cargo being loa ded
on the vehicle. That weight may n ot safely exceed the available
cargo and luggage load capac ity calculated in Step 4.
(6) If your vehicle will be towing a trailer, load from your tra iler will be
transferred to your vehicle. Consult this manual to determine h ow
this reduces the available cargo and luggage load capacity of y our
vehicle. ( P. 195)

tions, cargo capacity and load:

Vehicle load limits
◆Total load capacity (vehicle capacity weight): P. 538
Total load capacity means the co mbined weight of occupants, cargo
and luggage.
◆Seating capacity: P. 5 3 7
Seating capacity means the max imum number of occupants whose
estimated average weight is 150 lb. (68 kg) per person.
Even if the number of occupants are within the seating capacity , do
not exceed the tota l load capacity.
◆TWR (Trailer Weight Rating): P. 201
TWR means the maximum gross trai ler weight (trailer weight plus
its cargo weight) that your vehicle is able to tow.
◆Cargo capacity
Cargo capacity may increase or decrease depending on the weight
and the number o f occupants.
■Total load capacity and seating capacity
These details are also described on the tire and loading inform ation label.
(  P. 442)
Vehicle load limits include total load capacity, seating capaci ty,
TWR (Trailer Weight Rati ng) and cargo capacity.
