WARNING
■If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning light not
come on when you start the engine, this could mean that these systems are
not available to help protect you in an accident, which could result in death
or serious injury. Have the vehicle inspected by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional
immediately if this occurs.
NOTICE
■ To prevent damage to the engine and its components
The engine may be overheating if the high engine coolant temperature
warning light flashes or turns on. In this case, immediately stop the vehicle
in a safe place, and check the engine after it has cooled completely.

are met:
• The engine is adequately warmed up.
• The battery is sufficiently charged.
• The driver’s door is closed.
• The hood is closed.
• The driver’s seat belt is fastened.
• The clutch pedal is not being depressed.
• The shift lever is in N.
● In the following circumstances the engine may not be stopped by the Stop &
Start system. This is not a malfunction of the Stop & Start system.
• The engine coolant temperature is extremely high or low.
• The outside temperature is extremely low.
• The air conditioning system is being used when the vehicle interior tem-
perature is extremely high such as after the vehicle was parked under the
hot sun.
• The air conditioning system is being used when the outside temperature
is high or low.
• Vehicles with an automatic air conditioning system only: The windshield
defogger is being used.
• The battery is not sufficiently charged, or is undergoing a periodic
recharge.
• Due to traffic or other circumstances the vehicle is stopped repeatedly,
resulting in the amount of time the engine is stopped by the Stop & Start
system to become excessively high.
• The brake booster vacuum is low.
• A large amount of electricity is being used.
• At high altitude.
When the above conditions improve, the Stop & Start system will stop and

Winter driving tips
●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspect the condition of the battery.
● Have the vehicle fitted with four snow tires or purchase a set of tire
chains* for the front tires.
Ensure that all tires are the same size and brand, and that chains match
the size of the tires.
*: Tire chains cannot be mounted on the 15-inch tires.
Perform the following according to the driving conditions:
● 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.
● 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.
● Check for and remove any excess ice or snow that may have accu-
mulated on the exterior lights, vehicle’s roof, chassis, around the
tires or on the brakes.
● Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a man-
ner appropriate to the prevailing weather conditions.

3247-2. Maintenance
AYGO_OM_Europe_OM99Q24E
■ Does your vehicle need repairs?
Be on the alert for changes in performance and sounds, and visual tip-offs
that indicate service is needed. Some important clues are:
● Engine misses, stumbling or pinging
● Appreciable loss of power
● Strange engine noises
● A fluid leak under the vehicle (However, water dripping from the air condi-
tioning system after use is normal.)
● Change in exhaust sound (This may indicate a dangerous carbon monoxide
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,
pedal almost touches the floor, vehicle pulls to one side when braking
● Engine coolant temperature continually higher than normal
If you notice any of these clues, take your vehicle to any authorized Toyota
dealer or repairer, or another dul y qualified and equipped professional as
soon as possible. Your vehicle may need adjustment or repair.
WARNING
■ If your vehicle is not properly maintained
Improper maintenance could result in serious damage to the vehicle and
possible death or serious injury.
■ Handling of the battery
Battery posts, terminals and related accessories contain lead and lead com-
pounds which are known to cause brain damage. Wash your hands after
handling. ( P. 338)

Maintenance and care
AYGO_OM_Europe_OM99Q24E
WARNING
■When working near the electric cooling fans or radiator grille
Vehicles without a smart entry & start system
Be sure the engine switch is off. With the engine switch in the “ON” position,
the electric cooling fan may automatical ly start to run if the air conditioning
is on and/or the coolant temperature is high. ( P. 338)
Vehicles with a smart entry & start system
Be sure the engine switch is off. With the engine switch in IGNITION ON
mode, the electric cooling fan may automatically start to run if the air condi-
tioning is on and/or the coolant temperature is high. ( P. 338)
■ 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 filter
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 refilling, it may indicate a serious problem.
