SIENNA_OM_OM45472U_(U)
CAUTION
■When the vehicle is parked
● Always apply the parking brake, shift the shift lever to P, stop the engine
and lock the vehicle.
Do not leave the vehicle unattended while the engine is running.
● Do not touch the exhaust pipe while the engine is running or immediately
after turning the engine off.
Doing so may cause burns.
● Do not leave the engine running in an area with snow build-up, or where it
is snowing. If snowbanks build up around the vehicle while the engine is
running, exhaust gases may collect and enter the vehicle. This may lead
to death or a serious health hazard.
■ Exhaust gases
Exhaust gases include harmful carbon monoxide (CO), which is colorless
and odorless. Inhaling exhaust gases may lead to death or a serious health
hazard.
● If the vehicle is in a poorly ventilated area, stop the engine. In a closed
area, such as a garage, exhaust gases may collect and enter the vehicle.
This may lead to death or a serious health hazard.
● The exhaust system should be checked occasionally. If there is a hole or
crack caused by corrosion, damage to a joint or abnormal exhaust noise,
be sure to have the vehicle inspected and repaired by your Toyota dealer.
Failure to do so may allow exhaust gases to enter the vehicle, resulting in
death or a serious health hazard.

Shift ranges and their functions
●Automatically selecting gears between 1 and 6 according to
vehicle speed and driving conditi ons. But, the gear is limited
according to selected shift range.
● You can choose from 6 levels of engine braking force.
● A lower shift range will provide greater engine br aking force than
a higher shift range, and the engine speed will also increase.
■S mode
● When the shift range is 5 or lower, holding the shift lever toward “+” sets
the shift range to 6.
● To prevent excessive engine speed, a function was adopted that auto-
matically selects a higher shift range before the engine speed becomes
too high.
● To protect the automatic transaxle, a function is adopted that automati-
cally selects a higher shift range when the fluid temperature is high.
■ When driving with the cruise contro l or dynamic radar cruise control
Engine braking will not occur in S mode, even when downshifting to 5 or 4.
( P. 295, 300)
■ If the shift lever cannot be shifted from P
● P. 780
● Vehicles with AUTO ACCESS SEAT : If the AUTO ACCESS SEAT has
not been locked in place after being stowed, the shift lever cannot be
shifted from P.
