2023 TOYOTA TUNDRA HYBRID recommended oil

2004-2. Driving procedures
Owners Manual_USA_M0C052_en
*1: Shifting to the D position allows the system to select a gear suit-
able for the driving conditions.
Setting the shift lever to the D
position is recommended for nor-
mal driving.
*2: Selecting shift ranges using S mode restricts the upper limit of
the possible gear ranges, con-
trols engine brak ing force, and
prevents unnecessary upshifting.
■Driving on a downhill
On declines, there may be case
where the vehicle shifts down auto-
matically to obtain engine braking.
As a result of the downshifting, the engine speed may increase.
■To protect the a
utomatic trans-
mission
●If the tires spin continually when
the vehicle becomes stuck in mud,
dirt or snow, or if the accelerator
pedal is depressed and released
repeatedly while driving, the auto-
matic transmission temperature
may become too high and the
automatic transmission may be
damaged.
To avoid damaging the automatic
transmission, the system may
temporarily lock the gear. If the
automatic transmission tempera-
ture falls, the gear locking is can-
celed and the automatic
transmission is returned to the
normal operation.
●If the automatic tr ansmission fluid
temperature is high, “Transmis-
sion Oil Temp. High Stop in a Safe
Place and See Owner’s Manual”
will be displayed on the multi-
information display. Immediately
stop the vehicle in a safe place,
shift the shift lever to P and wait
until the warning message go off.
If the warning message go off, you
may start the vehicle again. If the
warning message do not go off,
contact your Toyota dealer.
■When driving with dynamic
radar cruise control with full-
speed range activated
Even when perform ing the following
actions with the intent of enabling
engine braking, engine braking will
not activate because dynamic radar
cruise control with full-speed range
will not be canceled.
●While driving in S mode, down-
shifting to 9, 8, 7, 6, 5 or 4.

Observe the following precautions
to reduce the risk of accidents.
Failure to do so may result in the
vehicle being unable to be driven
safely, and may cause death or
serious injury.
●Do not drive in excess of the
speed limit specifi ed for the tire
chains being used, or 30 mph
(50 km/h), whichever is lower.
●Avoid driving on bumpy road
surfaces or over potholes.
●Avoid sudden acceleration,
abrupt steering, sudden brak-
ing and shifting operations that
cause sudden engine braking.
●Slow down sufficiently before
