2-1. Driving procedures

When driving
CAUTION
■
When driving the vehicle
●If the smell of exhaust is noticed inside the vehicle, open the windows and
check that the back window is closed. Large amounts of exhaust in the
vehicle can cause driver drowsiness and an accident, resulting in death or
a serious health hazard. Have the vehicle inspected by your Toyota dealer
immediately.
● Do not shift the shift lever to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle\
control.
● Do not shift the shift lever to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle\
control.
● Do not shift the shift lever to D while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle\
control.
● Moving the shift lever to N while the vehicle is moving will disengage the
engine from the transmission. Engine braking is not available when N is
selected.
● During normal driving, do not turn off the engine. Turning the engine off
while driving will not cause loss of steering or braking control, but the
power assist to these systems will be lost. This will make it more difficult to
steer and brake, so you should pull over and stop the vehicle as soon as it
is safe to do so.
However, in the event of an emergency, such as if it becomes impossible
to stop the vehicle in the normal way: P. 655
● Use engine braking (downshift) to maintain a safe speed when driving
down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. ( P. 181)
● When stopped on an inclined surface, use the brake pedal and parking
brake to prevent the vehicle from rolling backward or forward and causing
an accident.

174 2-1. Driving procedures
CAUTION
■When the vehicle is parked
●If the shift lever is moved before the 4LO indicator turns on/off, the transfer
mode may not be shifted completely. The transfer mode disengages both
the front and rear driveshafts from the powertrain and allows the vehicle to
move regardless of the shift position. (At this time, the indicator blinks and
the buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic transmission is in
P. You or someone else could be seriously injured. You must complete the
shifting of the transfer mode. ( P. 244)
● 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) that is colorless and
odorless. Inhaling exhaust gases may lead to death or a serious health haz-
ard.
●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 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.
● Toyota does not recommend occupying the rear cargo area when it is fitted
with a slide-in camper, camper shell or other type cover while the engine is
running. This caution applies to bot h driving and stopped or parked situa-
tions with the engine running. Particular care should be taken to prevent
exhaust gases from entering camper bodies, trailers or other enclosures
on or around your vehicle. If exhaust fumes are detected, open all win-
dows and thoroughly ventilate the area.

When driving
■
Gear range display when driving in S mode
The current gear range is displayed on the combination meter. ( P. 182)
■ When driving with the cruise control system (if equipped)
The engine brake will not operate in the S mode, even when downshifting to
5 or 4 (6-speed models) or 4 or 3 (5-speed models). ( P. 223)
■ If the shift lever cannot be shifted from P
P. 643
■ If the S indicator does not come on even after shifting the shift lever to
S
This may indicate a malfunction in the automatic transmission system. Have
the vehicle inspected by your Toyota dealer, immediately.
(In this situation, the vehicle will operate as if the shift lever is in D.)
■ AI-SHIFT
The AI-SHIFT automatically shifts the gear to the optimal position according
to the driver performance and driving conditions.
The AI-SHIFT automatically operates when the shift lever is in the D posi-
tion. (Shifting the shift lever to the S position cancels the function.)
The engine speed may remain high after releasing the accelerator pedal.
This does not indicate a malfunction.
■ Downshifting restrictions wa rning buzzer (in the S mode)
To help ensure safety and driving performance, downshifting operation may
sometimes be restricted. In some circumstances, downshifting may not be
possible even when the shift lever is operated. (The warning buzzer will
sound twice.)
