2824-5. Using the driving support systems
■Stopping the engine
1 With the clutch pedal fully
depressed, depress the brake
pedal, and stop the vehicle.
2 Shift the shift lever to N
( P.186), and release the
clutch pedal.
The Stop & Start indicator will come on.
■Restarting the engine
Depress the clutch pedal.
The Stop & Start indicator will turn off.
■Operating conditions
●The Stop & Start system is operational
when all of the following conditions are met:
• Vehicles with a Multidrive: The brake
pedal is being depressed firmly. (Except when the vehicle comes to a
controlled stop while driving with the
dynamic radar cruise control with
full-speed range in vehicle-to-vehicle distance control mode [if equipped])
• Vehicles with a manual transmission:
The clutch pedal is not depressed. • The engine is adequately warmed up.
• The outside temperature is -5°C
(23°F) or higher. • The shift lever is in D or P (Multidrive)
or in N (manual transmission).
• The windshield defogger is off. • The selected driving mode is Normal
or Eco mode.
• The hood is closed. • The driver’s seat belt is fastened.
• The driver’s door is closed.
• The accelerator pedal is not being depressed.
●In the following situations the engine may not be stopped by the Stop &
Start system. This is not a malfunction
of the Stop & Start system. • The air conditioning system is being
used.
• The battery is undergoing a periodic recharge.
• The battery is not sufficiently charged,
such as if the vehicle has been parked for a long time and the battery charge
has decreased, the electric load is
large, the battery fluid temperature is excessively low or the battery has
deteriorated.
• The brake booster vacuum is low. • The vehicle is stopped on a steep
incline.
• The steering wheel is being operated. • Due to traffic or other circumstances
the vehicle is stopped repeatedly.
• The vehicle is being driven in a high altitude area.
• Engine coolant temperature or trans-
mission fluid temperature is extremely low or high.
• The battery fluid temperature is
extremely low or high. • For a while after the battery terminals
have been disconnected and recon-
nected. • For a while after the battery has been
replaced.
• When the elapsed time since the
engine was restarted is short.
●In the following situations, the engine
will restart automatically if the engine is stopped by the Stop & Start system.
(To enable stopping of the engine by
the Stop & Start system, drive the vehicle.)
• The air conditioning system is turned
on.

Maintenance and care
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 missing, 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 or clutch pedal
(vehicles with a manual transmission),
pedal almost touches the floor, vehicle pulls to one side when braking
●Engine coolant temperature continu-ally higher than normal ( P.89, 93)
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.

Maintenance and care
WA R N I N G
●Do not leave anything that may
burn easily, such as paper and
rags, in the engine compartment.
●Do not smoke, cause sparks or
expose an open flame to fuel or the battery. Fuel and battery fumes are
flammable.
●Be extremely cautious when work- ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
●Take care because brake fluid can
harm your hands or eyes and dam-
age painted surfaces. If fluid gets on your hands or in your eyes, flush
the affected area with clean water
immediately. If you still experience discomfort,
consult a doctor.
■When working near the electric
cooling fans or radiator grille
Be sure the engine switch is OFF. With the engine switch in ON, the
electric cooling fans may automati-
cally start to run if the air conditioning is on and/or the coolant temperature
is high. (P.476)
■Safety glasses
Wear safety glasses to prevent flying
or falling material, fluid spray, etc. from getting in your eyes.
NOTICE
■If you remove the air cleaner fil-
ter
Driving with the air cleaner filter removed may cause excessive
engine wear due to dirt in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to
go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refill-
ing, it may indicate a serious problem.

Maintenance and care
■Engine coolant reservoir
The coolant level is satisfactory if it
is between the “FULL” and “LOW”
lines on the reservoir when the
engine is cold.
Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the “LOW”
line, add coolant up to the “FULL” line.
( P.560)
■Intercooler coolant reservoir
The coolant level is satisfactory if it
is between the “F” and “L” lines on
the reservoir when the engine is
cold.
Reservoir cap
“F” line
“L” line
If the level is on or below the “L” line,
add coolant up to the “F” line. ( P.560)
■Coolant selection
Only use “Toyota Super Long Life Cool-
ant” or a similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with
long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deion-
ized water. (Minimum temperature:
-35°C [-31°F])
For more details about coolant, contact
any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
■If the coolant level drops within a
short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir caps, drain
cock and water pump.
If you cannot find a leak, have any authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer, test the cap and check for leaks in the cooling system.
NOTICE
■When replacing the engine oil
●Be careful not to spill engine oil on
the vehicle components.
●Avoid overfilling, or the engine
could be damaged.
●Check the oil level on the dipstick
every time you refill the vehicle.
●Be sure the engine oil filler cap is
properly tightened.

5628-2. Steps to take in an emergency
operate and to check for coolant
leaks from the radiator or hoses.
The fans operate when the air condi-
tioning system is tu rned on immediately after a cold start. Confirm that the fans
are operating by checking the fan
sound and air flow. If it is difficult to check these, turn the air conditioning
system on and off r epeatedly. (The fans
may not operate in freezing tempera- tures.)
7 If the fans are not operating:
Stop the engine immediately
and contact any authorized
Toyota retailer or Toyota author-
ized repairer, or any reliable
repairer.
If the fans are operating: Have
the vehicle inspected at the
nearest any authorized Toyota
retailer or Toyota authorized
repairer, or any reliable repairer.
WA R N I N G
■When inspecting under the hood
of your vehicle
Observe the following precautions.
Failure to do so may result in serious
injury such as burns.
●If steam is seen coming from under
the hood, do not open the hood until the steam has subsided. The
engine compartment may be very
hot.
●Keep hands and clothing (espe-
cially a tie, a scarf or a muffler) away from the fans and belts. Fail-
ure to do so may cause the hands
or clothing to be caught, resulting in serious injury.
●Do not loosen the coolant reservoir caps while the engine and radiator
are hot.
High temperature steam or coolant could spray out.
NOTICE
■When adding engine coolant
Add coolant slowly after the engine
has cooled down sufficiently. Adding cool coolant to a hot engine too
quickly can cause damage to the
engine.
■To prevent damage to the cooling
system
Observe the following precautions:
●Avoid contaminating the coolant with foreign matter (such as sand or
dust etc.).
●Do not use any coolant additive.
