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 rain,
because there may be a layer of water between the tires and the road sur-
face, preventing the steering 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 TOW/HAUL mode is selected (if
equipped)
■ Breaking in your new Toyota
To extend the life of the vehicle, observing the following precautions 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 whenever 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. 516)
■ 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 combined 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 that will be riding in your vehicle.
(3) Subtract the combined weight of the driver and passengers from
XXX kg or XXX lbs.
(4) The resulting figure equals the available amount of cargo and lug- gage load capacity.
For example, if the “ XXX” amount equals 1400 lbs. and there will be
five 150 lb passengers in your v ehicle, 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 loaded on the vehicle. That weight ma y not safely exceed the available
cargo and luggage load capacity calculated in Step 4.
(6) If your vehicle will be towing a tr ailer, load from your trailer will be
transferred to your vehicle. Consult this manual to determine how
this reduces the available cargo and luggage load capacity of your
vehicle. ( P. 156)
Take notice of the following information about storage precau-
tions, cargo capacity and load:
Capacity and distribution

Vehicle load limits
◆Total load capacity (vehicle capacity weight): P. 5 0 2
Total load capacity means the combined weight of occupants, cargo
and luggage.
◆Seating capacity
Regular Cab models
3 occupants
Double Cab and CrewMax models
Vehicles with front separated type seats —
5 occupants (Front 2, Rear 3)
Vehicles with front bench type seat —
6 occupants (Front 3, Rear 3)
Seating capacity means the maxi mum 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 total load capacity.
◆TWR (Trailer Weight Rating):  P. 162
TWR means the maximum gross trailer 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 of occupants.
■Total load capacity and seating capacity
These details are also described on the tire and loading information label.
(  P. 425)
Vehicle load limits include total load capacity, seating capacity,
TWR (Trailer Weight Rati ng) and cargo capacity.

Trailer towing
Contact your Toyota dealer for further information about additional
requirements such as a towing kits, 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 safe ty of others, you must not over-
load your vehicle or trailer. You must also ensure that you are
using appropriate towing equipmen t, that the towing equipment
has been installed correctly a nd used properly, and that you
employ the requisite driving habits.
Vehicle-trailer stability and braking performance are affected by
trailer stability, brake performance and setting, trailer brakes,
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.

■GCWR (Gross Combination Weight Rating)
The maximum allowable gross
combination weight. The gross
combination weight is the sum
of the total vehicle weight
(including the occupants, cargo
and any optional equipment
installed on the vehicle) and the
weight of the trailer being towed
(including the cargo in the
trailer).
■GVWR (Gross Vehicle Weight Rating)
The maximum allowable gross
vehicle weight. The gross vehi-
cle weight is the total weight of
the vehicle. When towing a
trailer, it is the sum of the vehi-
cle weight (including the occu-
pants, cargo and any optional
equipment installed on the vehi-
cle) and the tongue weight.
■GAWR (Gross Axle Weight Rating)
The maximum allowable gross
axle weight. The gross axle
weight is the load placed on
each axle (front and rear).

Rear GAWR

1604-1. Before driving
■TWR (Trailer Weight Rating)
The maximum allowable gross
trailer weight. The gross trailer
weight is the sum of the trailer
weight and the weight of the
cargo in the trailer.
TWR is calculated assuming
base vehicle with one driver,
one front passenger, towing
package (if available), hitch and
hitch systems (if required).
Additional optional equipment, passengers and cargo in the vehicle will
reduce the trailer weight rating so as not to exceed GCWR, GVWR and
GAWR.
If the gross trailer weight exceeds 3000 lb. (1360 kg), it is recommended
to use a trailer with 2 or more axles.
■
Unbraked TWR (Unbraked Trailer Weight Rating)
The trailer weight rating for tow-
ing a trailer without a trailer ser-
vice brake system.
■Tongue Weight
The load placed on the trailer
hitch ball. ( P. 167)
(With brakes)
(Without brakes)

1624-1. Before driving
Confirm that the gross trailer weight, gross combination weight, gross
vehicle weight, gross axle weight and tongue weight are all within the
limits.
