Approximately five hours after the engine is turned off, you ma y hear sound
coming from under the vehicle for several minutes. This is the sound of a fuel

fication with non-genuine Toyota products could affect its perf ormance, safety
or durability, and may even violate governmental regulations. In addition,
damage or performance problems resulting from the modification may not be

Operation of each component
From inside (if equipped)
Press the switch to fold the mir-
rors.
Press it again to extend them to
the original position.
The mirrors can be manually slid
outward to improve visibility
around wide trailers.
When the mirror select switch is in the L or R position, the ou tside rear
view mirrors will automatically a ngle downwards when the vehicl e is
reversing in order to give a better view of the ground.
To disable this function, move the mirror select switch to the neutral
position (between L and R).
■Adjusting the mirror angle when the vehicle is reversing
With the shift lever in R, adjust the mirror angle at a desired posi-
tion. The adjusted angle will be memorized and the mirror will auto-
matically tilt to the memorized angle whenever the shift lever is
shifted to R from next time.
The memorized downward tilt position of the mirror is linked to the nor-
mal position (angle adjusted with the shift lever in other than R). There-
fore, if the normal position is changed after adjustment, the t ilt position
will also change.
When the normal position is changed, readjust the angle in reve rsing.

may cause the vehicle to move or the vehicle may move suddenly if the
accelerator pedal is accidentally depressed.
■ Avoiding damage to vehicle parts
● Do not turn the steering wheel fully in either direction and ho ld it there for
an extended period of time.
Doing so may damage the power steering pump.
● When driving over bumps in the road, drive as slowly as possibl e to avoid
damaging the wheels, underside of the vehicle, etc.

not change or the engine may not start.
● If attempting to restart the engine immediately after turning t he engine
switch off, the engine may not start in some cases. After turni ng the engine

WARNING
■ When starting the engine
Always start the engine while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the engine under any circumsta nces.
Doing so may cause an accident resulting in death or serious in jury.
■ Caution while driving
If engine failure occurs while the vehicle is moving, do not lo ck or open the
doors until the vehicle reaches a safe and complete stop. Other wise, the
steering lock function will activate and this may lead to an ac cident, result-
ing in death or serious injury.
■ Stopping the engine in an emergency
If you want to stop the engine in an emergency while driving th e vehicle,
press and hold the engine switch for more than 2 seconds, or pr ess it briefly
3 times or more in succession. ( P. 475)
However, do not touch the engine switch while driving except in an emer-
gency. Turning the engine off while driving will not cause loss of steering or
braking control, however, power assist to the steering will be lost. This will
make it more difficult to steer smoothly, so you should pull ov er and stop the
vehicle as soon as it is safe to do so.
■ When parking (except for New Caledonia)
Exhaust gases include harmful carbon monoxide (CO), which is colorless
and odorless. Observe the following precautions.
Failure to do so may cause exhaust gases to enter the vehicle a nd may
lead to an accident caused by light-headedness, or may lead to death or a
serious health hazard.
● If the vehicle is in a poorly ventilated area or a closed area, such as a
garage, stop the engine.
● Do not leave the vehicle with the engine running for a long tim e. If such a
situation cannot be avoided, park the vehicle in an open space and ensure
that exhaust fumes do not enter the vehicle interior.
● 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.

■If the “S” indicator does not come on even after shifting the s hift lever to
S
This may indicate a malfunction in the automatic transmission s ystem. Have
the vehicle inspected by your Toyota dealer, immediately.
(In this situation, the transmission will operate in the same m anner as when
the shift lever is in D.)
■ Downshifting restrictions warning buzzer (S mode)
To help ensure safety and driving performance, downshifting ope ration may
sometimes be restricted. In some circumstances, downshifting ma y not be
possible even when the shift lever is operated. (A buzzer will sound twice.)
■ Transmission protection function
If the tires spin continually when the vehicle becomes stuck in mud, dirt or
snow, the automatic transmission temperature may become too high and
cause damage.
To avoid the damaging the automatic transmission, the system may tempo-
rarily lock the gear in 1st.
If the automatic transmission temperature falls, the gear locki ng is canceled
and returns the automatic transmission to the normal operation.
WARNING
■ When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.
■ To prevent an accident when releasing the shift lock
Before pressing the shift lock override button, make sure to se t the parking
brake and depress the brake pedal.
If the accelerator pedal is accidentally depressed instead of t he brake pedal
when the shift lock override button is pressed and the shift le ver is shifted
out of P, the vehicle may suddenly start, possibly leading to a n accident
resulting in death or serious injury.
