2013 TOYOTA IQ overheating

108 2-1. Driving procedures
CAUTION
■Exhaust gases
Exhaust gases include harmful carbon monoxide (CO) that is colorless and
odorless. Inhaling exhaust gases may lead to death or a serious health haz-
ard.
●If the vehicle is in a poorly ventilated area, stop the engine. In a closed
area, such as a garage, exhaust gases may collect and enter the vehicle.
This may lead to death or a serious health hazard.
● The exhaust should be checked occasionally. If there is a hole or crack
caused by corrosion, damage to a joint or abnormal exhaust noise, be
sure to have the vehicle inspected and repaired by your Scion dealer. Fail-
ure to do so may allow exhaust gases to enter the vehicle, resulting in
death or a serious health hazard.
■ When taking a nap in the vehicle
Always turn the engine off. Otherwise, you may accidentally move the shift
lever or depress the accelerator pedal, which could cause an accident or fire
due to engine overheating. Additionally, if the vehicle is parked in a poorly
ventilated area, exhaust gases may collect and enter the vehicle, leadin\
g to
death or a serious health hazard.
■ When braking the vehicle
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and may cause one
side of the vehicle to brake differently than the other side. Also the parking
brake may not securely hold the vehicle.
● If the power brake assist function does not operate, do not follow other
vehicles closely and avoid downhills or sharp turns that require braking.
In this case, braking is still possible, but it will require more force on the
pedal than usual. Braking distance may also increase.
● Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted
brakes.

When driving
NOTICE
■
Before driving
Fully release the parking brake.
Driving the vehicle with the parking brake set will lead to brake components
overheating, which may affect braking performance and increase brake
wear.

120 2-2. Instrument cluster
Instrument panel light controlThe brightness of the instrument panel lights can be adjusted.
When the tail lights/headlights
are turned on, the brightness
level can changed with each
press of the switch.
● Instrument panel light control display
Displays the instrument pa nel light control display.
NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
● The engine may be overheating if the high engine coolant temperature
warning light flashes or comes on. In this case, immediately stop the vehi-
cle in a safe place, and check the engine after it has cooled completely.
(
P. 308)

142 2-4. Using other driving systems
■If the slip indicator comes on
There is a malfunction in the TRAC and VSC systems. Contact your Scion
dealer and have your Scion inspected.
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may
be heard. This does not indicate a malfunction.
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur,
refrain from excessive steering input or stop the vehicle and turn the engine
off. The EPS system should return to normal within 10 minutes.
CAUTION
■The ABS does not operate effectively when
●The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on the wet or slick
road.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the fol-
lowing situations.
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with potholes or uneven roads
■ When VSC is activated
The slip indicator flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator flashes.

5-2. Steps to take in an emergency
If your vehicle overheats
In the following cases, the vehicle may be overheating.
●High engine coolant temperature warning light ( P. 274) flashes
or comes on, and engine output falls (There is no speed).
● Steam is coming out from the engine compartment.
Perform the following steps.
Stop the vehicle in a safe place, turn off the air conditioning
system, and stop the engine.
If steam is coming out:
When no more steam is coming out has been confirmed,
carefully open the hood.
If there is no steam coming out:
Carefully open the hood. After the engine has cooled
down sufficiently, inspect the
radiator core (radiator), hoses,
etc. for any leaks.
If there is a large quantity of
engine coolant leaking, imme-
diately contact your Scion
dealer.
Inspect the amount of engine
coolant by checking if the res-
ervoir level is between FULL
and LOW lines.
