Press the “DAC” switch while the
system is in operation.
The downhill assist control system indi-
cator will flash as the system gradually
ceases operation, and will turn off when
the system is fully off.
Press the “DAC” switch while the down-
hill assist control system indicator is
flashing to start the system again.
■Operating tips
The system will operate when the shift lever is in a position other than P.
■If the downhill assist control sys-tem indicator flashes
●In the following situations, the indica-tor flashes and the system will not
operate: • The shift lever is in P.• The accelerator or brake pedal is
depressed. • The vehicle speed exceeds approxi-mately 30 km/h (18 mph).
• The brake system overheats.
●In the following situation, the indicator flashes to alert the driver, but the sys-tem will operate:
• The shift lever is in N. • The “DAC” switch is turned off while the system is operating.
The system will gradually ceases opera- tion. The indicator will flash during oper-ation, and then go off when the system
is fully off.
■When the downhill assist control
system is operated continuously
This may cause the brake actuator to overheat. In this case, the downhill
assist control system will stop operating, a buzzer will sound and the downhill assist control system indicator will start
flashing, and “Traction Control Turned OFF” will be shown on the multi-infor-mation display. Refrain from using the
system until the downhill assist control system indicator stays on and “Traction Control Turned OFF” the message goes
off. (The vehicle can be driven normally during this time.)
■Sounds and vibrations caused by the downhill assist control system
●A sound may be heard from the engine compartment when the hybrid
system is started or just after the vehi- cle begins to move. This sound does not indicate that a malfunction has
occurred in downhill assist control system.
●Either of the following conditions may occur when the downhill assist control system is operating. None of these
are indicators that a malfunction has occurred.• Vibrations may be felt through the
vehicle body and steering. • A motor sound may be heard after the vehicle comes to a stop.
■System malfunction

4-6.Driving tips
When using Eco drive mode, the
torque corresponding to the accel-
erator pedal depression amount
can be generated more smoothly
than it is in normal conditions. In
addition, the operation of the air
conditioning system (heating/cool-
ing) will be minimized, improving
the fuel economy. ( P. 3 2 2 )
The Eco-friendly driving is possible
by keeping the indicate of Hybrid
System Indicator within Eco area.
( P.96, 102)
Shift the shift lever to D when
stopped at a traffic light, or driving
in heavy traffic etc. Shift the shift
lever to P when parking. When
using the N, there is no positive
effect on fuel consumption. In the
N, the gasoline engine operates but
electricity cannot be generated.
Also, when using the air condition-
ing system, etc., the hybrid battery
(traction battery) power is con-
sumed.
 Drive your vehicle smoothly.
Avoid abrupt acceleration and
deceleration. Gradual accelera-
tion and deceleration will make
more effective use of the electric
motor (traction motor) without
having to use gasoline engine
power.
 Avoid repeated acceleration.
Repeated acceleration con-
sumes hybrid battery (traction
battery) power, resulting in poor
fuel consumption. Battery power
can be restored by driving with
the accelerator pedal slightly
released.
Make sure to operate the brakes
gently and in a timely manner. A
greater amount of electrical energy
can be regenerated when slowing
down.
Repeated acceleration and decel-
eration, as well as long waits at traf-
fic lights, will lead to bad fuel
economy. Check traffic reports
before leaving and avoid delays as
much as possible. When driving in

4-6. Driving tips
a traffic jam, gently release the
brake pedal to allow the vehicle to
move forward slightly while avoid-
ing overuse of the accelerator
pedal. Doing so can help control
excessive gasoline consumption.
Control and maintain the vehicle at
a constant speed. Before stopping
at a toll booth or similar, allow
plenty of time to release the accel-
erator and gently apply the brakes.
A greater amount of electrical
energy can be regenerated when
slowing down.
Use the air conditioning only when
necessary. Doing so can help
reduce excessive gasoline con-
sumption.
In summer: When the ambient tem-
perature is high, use the recircu-
lated air mode. Doing so will help to
reduce the burden on the air condi-
tioning system and reduce fuel con-
sumption as well.
In winter: Because the gasoline
engine will not automatically cut out
until it and the interior of the vehicle
are warm, it will consume fuel. Also,
fuel consumption can be improved
by avoiding overuse of the heater.
Make sure to check the tire inflation
pressure frequently. Improper tire
inflation pressure can cause poor
fuel economy.
Also, as snow tires can cause large
amounts of friction, their use on dry
roads can lead to poor fuel econ-
omy. Use tires that are appropriate
for the season.
Carrying heavy luggage will lead to
poor fuel economy. Avoid carrying
unnecessary luggage. Installing a
large roof rack will also cause poor
fuel economy.
Since the gasoline engine starts up
and cuts out automatically when
cold, warming up the engine is
unnecessary. Moreover, frequently
driving short distances will cause
the engine to repeatedly warm up,
which can lead to excess fuel con-
sumption.

request that a record of maintenance
be kept.
■Does your vehicle need repairs?
Be on the alert for changes in perfor- mance and sounds, and visual tip-offs
that indicate service is needed. Some important clues are:
●Engine misses (misfire), stumbling or pinging
●Appreciable loss of power
●Strange engine noises
●A fluid leak under the vehicle (How-ever, water dripping from the air con-
ditioning system after use is normal.)
●Change in exhaust sound (This may
indicate a dangerous carbon monox- ide leak. Drive with the windows open and have the exhaust system checked
immediately.)
●Flat-looking tires, excessive tire
squeal when cornering, uneven tire wear
●Vehicle pulls to one side when driven straight on a level road
●Strange noises related to suspension movement
●Loss of brake effectiveness, spongy feeling brake pedal, pedal almost touches the floor, vehicle pulls to one
side when braking
●Engine coolant temperature continu- ally higher than normal ( P.95, 100)
If you notice any of these clues, take
your vehicle to any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer as soon as possi-
ble. Your vehicle may need adjustment or repair.
