n When connecting and disconnecting a trailer
Set the electronically modulated air suspension system to LO mode and
push the HEIGHT CONTROL OFF switch to turn off the rear height control
air suspension. (if equipped)
n Break-in schedule
If your vehicle is new or equipped with any new power train components
(such as an engine, transmission, differential and wheel bearing), Toyota
recommends that you do not tow a trailer until it has been driven for over 500
miles (800 km).
However, avoid full throttle acceleration.
Maintenance
n
l If you tow a trailer, your vehicle will require more frequent maintenance
due to the additional load. (See "Scheduled Maintenance Guide" or
"Owner's Manual Supplement".)
l Retighten the fixing bolts of the towing ball and bracket after approxi-
mately 600 miles (1000 km).
CAUTION
Trailer towing precautions
n
l Follow all the instructions described in this section. Failure to do so could
cause an accident resulting in death or serious injury.
Exceeding the towing capacity, GVWR, GCWR or GAWR can cause an
l
accident resulting in death or serious injuries.
n To avoid accident or injury
l Do not exceed the trailer hitch assembly weight, gross vehicle weight,
gross axle weight and trailer tongue load capacities.
Do not exceed 45 mph (72 km/h) or the posted towing speed limit, which-
l
ever is lower. As instability (swaying) of the towing vehicle-trailer combina-
tion increases as speed increases, exceeding 45 mph (72 km/h) may
cause loss of control.
l Do not use cruise control when you are towing.
l Slow down and downshift before descending steep or long downhill
grades. Do not make sudden downshifts.
