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. 304)
• When the AUTO LSD system is turned on. (P. 299)
• 4WD models: The four-wheel drive control switch is in “4L” pos ition.
(P. 296)

■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. 610)
■ 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. 171)

tions, cargo capacity and load:

Vehicle load limits
◆Total load capacity (vehicle capacity weight): P. 594
Total load capacity means the co mbined weight of occupants, cargo
and luggage.
◆Seating capacity

Even if the number of occupants are within the seating capacity , do
not exceed the tota l load capacity.
◆TWR (Trailer Weight Rating): P. 177
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.

Trailer towing
Contact your Toyota dealer for further information about additi onal
requirements such as a towing kit, etc.
Your vehicle is designed primarily as a passenger-and-load-car-
rying vehicle. Towing a trailer can have an adverse impact on
handling, performance, braking, durability, and fuel consump-
tion. For your safety and the safety of others, you must not ov er-
load your vehicle or trailer. You must also ensure that you are
using appropriate towing equipm ent, that the towing equipment
has been installed correctly a nd used properly, and that you
employ the requisite driving habits. (P. 192)
Vehicle-trailer stability and braking performance are affected by
trailer stability, brake performance and setting, trailer brake s,
the hitch and hitch systems (if equipped).
To tow a trailer safely, use extreme care and drive the vehicle in
accordance with your trailer’s characteristics and operating
conditions.
Toyota warranties do not apply to damage or malfunction
caused by towing a trailer for commercial purposes.
