WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift
lever or depress the accelerator pedal, this could cause an acc ident or fire
due to engine overheating. Additionally, if the vehicle is parked in a poorly
ventilated area, exhaust gases may collect and enter the vehicl e, leading to
death or a serious health hazard.
■ When braking
● When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause
one side of the vehicle to brake differently than the other side. Also, the
parking brake may not securely hold the vehicle.
● If the brake booster device does not operate, do not follow oth er vehicles
closely and avoid hills or shar p turns that require braking.
In this case, braking is still possible, but the brake pedal should be
depressed more firmly than usual. Also, the braking distance will increase.
● Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted
brakes.
● The brake system consists of 2 individual hydraulic systems; if one of the
systems fails, the other will still operate. In this case, the brake pedal
should be depressed more firmly than usual and the braking dist ance will
increase.
If this happens, do not continue to drive the vehicle. Have you r brakes
fixed immediately.

■When driving the vehicle
● Do not depress the accelerator and brake pedals at the same tim e during

pedals at the same time to hold the vehicle on a hill.
■ When parking the vehicle
Always set the parking brake, and shift the shift lever to P. Failure to do so
may cause the vehicle to move or the vehicle may accelerate sud denly if

Trailer towing
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 requisi te driving habits.
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.
Contact your Toyota dealer for further information about addi-
tional requirements such as a towing kit, etc.

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 systems (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 r ecommended
to use a trailer with 2 or more axles.
