When driving
■Hill-start assist control will not operate when (if equipped)
●The shift lever is in the P, R or N positions.
● The rear differential is locked.
■ If the brake system overheats
TRAC and hill-start control will cease operation and a buzzer will sound to
alert the driver. Stop the vehicle in a safe place. (There is no problem with
continuing normal driving.)
CAUTION
■The ABS does not opera te effectively when
● The limits of tire gripping performance have been exceeded.
● The vehicle hydroplanes while driving at high speed on the wet or slick
road.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the fol-
lowing situations.
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with pothol es or roads with uneven roads
■ When VSC and Trailer Sway Control are activated
The slip indicator flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator flashes.
■ TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if TRAC is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
■ If the hill-start assist contro l does not operate effectively
Do not overly rely on the hill-start assist control. The hill start assist control
may not operate effectively on steep inclines and roads covered in ice.

CAUTION
■Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total
load capacity. In addition, make sure that the tires are inflated to the appro-
priate tire pressure level.
The ABS, VSC, TRAC and Trailer Sway Control will not function correctly if
different tires are fitted on the vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.
■ Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause the system to malfunction.
■ Trailer Sway Control precaution
The Trailer Sway Control system is not able to reduce trailer sway in all situ-
ations. Depending on many factors such as the conditions of the vehicle,
trailer, road surface, and driving environment, the Trailer Sway Control sys-
tem may not be effective. Refer to your trailer owner’s manual for information
on how to tow your trailer properly.
■ If trailer sway occurs
Observe the following precautions.
Failing to do so may cause death or serious injury.
●Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering wheel.
● Begin releasing the accelerator pedal immediately but very gradually to
reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle
and trailer should stabilize. ( P. 229)

204 2-5. Driving information
(6) If your vehicle will be towing a trailer, 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.
Calculation formula for your vehicle
Cargo capacity
Total load capacity (vehicle
capacity weight) (P. 518)
When 2 people with the combined weight of A lb. (kg) are riding in
your vehicle, which has a total load capacity (vehicle capacity weight)
of B lb. (kg), the available amount of cargo and luggage load capacity
will be C lb. (kg) as follows:
B
*2 lb. (kg)  A*1 lb. (kg) = C*3 lb. (kg)
*1: A = Weight of people
*2: B = Total load capacity
*3: C = Available cargo and luggage load
In this condition, if 3 more passengers with the combined weight of D
lb. (kg) get on, the available carg o and luggage load will be reduced E
lb. (kg) as follows:
C lb. (kg)  D*4 lb. (kg) = E*5 lb. (kg)
*4: D = Additional weight of people
*5: E = Available cargo and luggage load

Vehicle load limits
■Total load capacity and seating capacity
These details are also described on the tire and loading information
label. (P. 431)
Vehicle load limits include total load capacity, seating capacity,
TWR (Trailer Weight Rating) and cargo capacity.
■ Total load capacity (vehicle capacity weight): ( P. 518)
Total load capacity means the combined weight of occupants,
cargo and luggage.
■ Seating capacity:
Access Cab models
2 or 4 occupants (Front 2, Rear 0 or 2)
Double Cab models 5 occupants (Front 2, Rear 3)
Seating capacity means the ma ximum 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. 218, 519)
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.

Trailer towing
Your vehicle is designed primarily as a passenger-and-load-carrying
vehicle. Towing a trailer can have an adverse impact on handling,
performance, braking, durability, and fuel consumption. For your
safety and the safety of others, yo u must not overload your vehicle
or trailer. You must also ensure that you are using appropriate tow-
ing equipment, that the towing eq uipment has been installed cor-
rectly and used properly, and that you employ the requisite driving
habits.
Vehicle-trailer stability and braki ng 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 condi-
tions.
Toyota warranties do not apply to damage or malfunction caused by
towing a trailer for commercial purposes.
Contact your Toyota dealer for fu rther information about additional
requirements such as towing kits, etc.

Towing related terms■ 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 Vehi cle Weight Rating)
The maximum allowable gross
vehicle weight. The gross vehicle
weight is the total weight of the
vehicle. When towing a trailer, it
is the sum of the vehicle weight
(including the occupants, cargo
and any optional equipment
installed on the vehicle) 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).
■ 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 sys-
tems (if required).
Additional optional equipment,
passengers and cargo in the vehi-
cle 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 recom-
mended to use a trailer with 2 or
more axles.
