Driving
When the following unusual
operation is performed with the
accelerator pedal depressed,
the hybrid system output may be
restrained.
• When the shift lever is shifted to R
*.
• When the shift lever is shifted
from P or R to forward drive
shift position such as D
*.
When the system o perates, a mes-
sage appears on the multi-informa-
tion display. Read the message and
follow the instruction.
*: Depending on the situation, the shift position may not be
changed.
■Drive-Start Control (DSC)
When the TRAC is turned off
(  P.376), sudden start restraint
control also does not operate. If
your vehicle have trouble escaping
from the mud or fr esh snow due to
sudden start restraint operation,
deactivate TRAC ( P.376) so that
the vehicle may become able to
escape from the mud or fresh snow.
Also, sudden start restraint control
will not operate in the following con-
ditions:
●When the front-wheel drive control
switch is in “4H” or “4L” position.
(4WD models only)
●When AUTO LSD mode, the drive
start control does not operate. (if
equipped)
●When Multi-terrain Select is
selected. (if equipped)
NOTICE
■If you get a flat tire while driv-
ing
A flat or damaged tire may cause
the following situations. Hold the
steering wheel firmly and gradu-
ally depress the brake pedal to
slow down the vehicle.
●It may be difficult to control your
vehicle.
●The vehicle will make abnormal
sounds or vibrations.
●The vehicle will lean abnor-
mally.
Information on what to do in case
of a flat tire ( P.515)
■When encountering flooded
roads
Do not drive on a road that has
flooded after heavy rain, etc.
Doing so may cause the following
serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by
water immersion
In the event that you drive on a
flooded road an d the vehicle
becomes flooded or stuck in mud
or sand, be sure to have your Toy-
ota dealer check the following:
●Brake function
●Changes in quantity and quality
of oil and fluid used for the
engine, transmission, transfer
(4WD vehicles), differential, etc.
●Lubricant condition for the pro-
peller shaft, bearings and sus-
pension joints (where possible),
and the function of all joints,
bearings, etc.

trol [DSC])

2004-2. Driving procedures
Owners Manual_USA_M0C031_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 (if equipped) or
cruise control activated (if
equipped)
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
or cruise control will not be can-
celed.
●While driving in S mode, down-
shifting to 9, 8, 7, 6, 5 or 4.

NOTICE
■To prevent water damage
Take all necessary safety mea-
sures to ensure that water dam-
age to the engine, hybrid system
or other components does not
occur.
●Water entering the engine air
intake will cause severe engine
damage.
●Water entering the automatic
transmission will cause deterio-
ration in shift quality, locking up
of your transmission accompa-
nied by vibration, and ultimately
damage.
●Water can wash the grease
from wheel bearings, causing
rusting and premature failure,
and may also enter the differen-
tials, transmission and transfer
case, reducing the gear oil’s
lubricating qualities.
■When you drive through
water
●If driving through water, such as
when crossing shallow streams,
first check the depth of the
water and the bottom of the riv-
erbed for firmness. Drive slowly
and avoid deep water.
●When crossing a river or a pud-
dle, be sure to cross it without
stopping midway. If you stop or
drive at extremely low speeds in
water, water may enter the vehi-
cle and damage the hybrid bat-
tery making the vehicle unable
to be driven.
■Inspection after off-road driv-
ing
●Sand and mud that has accu-
mulated around brake discs
may affect braking efficiency
and may damage brake system
components.
●Always perform a maintenance
inspection after each day of off-
road driving that has taken you
through rough terrain, sand,
mud, or water. For scheduled
maintenance information, refer
to the “Scheduled Maintenance
Guide” or “Owner’s Manual
Supplement”.

When trouble arises
When using a flat-bed truck to
transport the vehicle, use tire
strapping belts. Refer to the
owner’s manual of the flat-bed
truck for the tire strapping
method.
In order to suppress vehicle
movement during transporta-
tion, set the parking brake and
turn the power switch off.
Your vehicle has not towing
hook. If towing is necessary, we
recommend having your vehicle
towed by your Toyota dealer or
commercial towing service. 
Fluid leaks under the vehicle.
(Water dripping from the air
conditioning after use is nor-
mal.)
 Flat-looking tires or uneven
tire wear
 Engine coolant temperature
gauge needle continually
points higher than normal.
 Voltmeter continually points
higher or lower than normal.
 Engine oil pressure gauge
continually points lower than
normal.
 Automatic transmission fluid
temperature warning mes-
sage is displayed
 Changes in exhaust sound
 Excessive tire squeal when
cornering
 Strange noises related to the
suspension system
