nThe meters and display illuminate when
The engine switch is in the “ON” position.
n Outside temperature display
lIn the following situations, the correct outside temperature may not be dis-
played, or the display may take longer than normal to change.
• When stopped, or driving at low speeds (less than 9 mph [15 km/h])
• When the outside temperature has changed suddenly (at the entrance/
exit of a garage, tunnel, etc.)
l If “  ” is displayed continuously, the system may be malfunctioning. Take
your vehicle to your Scion dealer.
NOTICE
n To prevent damage to the engine and its components
lDo not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
l The engine may be overheating if the engine coolant temperature gauge
enters the red zone. In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. (P. 288)

4-6. Driving tips
lUse fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
l Have a service technician ins pect the condition of the battery.
l Have the vehicle fitted with four snow tires.
Ensure that all tires are the same size and brand.
Perform the following accordin g to the driving conditions:
l Do not try to forcibly open a window or move a wiper that is frozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to prevent it from freezing.
l To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
l Check for and remove any excess ice or snow that may have accu-
mulated on the exterior lights, ve hicle’s roof, chassis, around the
tires or on the brakes.
l Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
Winter driving tips
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a man-

Scion iM_U (12J49U)
WARNING
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions.
nWhen working on the engine compartment
lKeep hands, clothing and tools away from the moving fan and engine
drive belt.
l Be careful not to touch the engine, radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil and other fluids may also be hot.
l Do not leave anything that may burn easily, such as paper and rags, in the
engine compartment.
l Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
l Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
n When working near the electric cooling fan or radiator grille
Be sure the engine switch is off. With the engine switch in the “ON” position,
the electric cooling fan may automatically start to run if the air conditioning
is on and/or the coolant temperature is high. ( P. 214)
n Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in your eyes.
NOTICE
nIf you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.

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. 288)
nCoolant selection
Only use “Toyota Super Long Life Coolant” 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.
For the U.S.A.: “Toyota Super Long Life Coolant” is a mixture of 50% cool- ant and 50% deionized water. (Minimum temperature: -31 F
[-35 C])
For Canada: “Toyota Super Long Life Coolant” is a mixture of 55% cool- ant and 45% deionized water. (Minimum temperature: -44 F
[-42 C])
For more details about engine coolant, contact your Scion dealer.
n 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 your Scion dealer test the cap and check for
leaks in the cooling system.
