STARTING AND DRIVING213
DAlways slow down in gusty crosswinds.
This will allow you much better control.
DDrive slowly onto curbs and, if pos-
sible, at a right angle. Avoid driving
onto high, sharp−edged objects and
other road hazards. Failure to do so
can lead to severe tire damage such
as a tire burst.
Drive slowly when passing over bumps
or travelling on a bumpy road. Other-
wise, the impact could cause severe
damage to the tires and/or wheels.
DWhen parking on a hill, turn the front
wheels until they touch the curb so
that the vehicle will not roll. Apply the
parking brake, and place the transmis-
sion in “M(1)”, “E(1)” or “R” (multi−
mode manual transmission), or first or
reverse (manual transmission). If nec-
essary, block the wheels.
DWashing your vehicle or driving through
deep water may get the brakes wet. To
see whether they are wet, check that
there is no traffic near you, and then
press the pedal lightly. If you do not
feel a normal braking force, the brakes
are probably wet. To dry them, drive
the vehicle cautiously while lightly
pressing the brake pedal with the park-
ing brake applied. If they still do not
work safely, pull to the side of the road
and call any authorized Toyota dealer
or repairer, or another duly qualified
and equipped professional, for assis-
tance.
CAUTION
DBefore driving off, make sure the
parking brake is fully released and
the parking brake reminder light is
off.
DDo not leave your vehicle unat-
tended while the engine is running.
DDo not rest your foot on the brake
pedal while driving. It can cause
dangerous overheating, needless
wear, and poor fuel economy.
DTo drive down a long or steep hill,
reduce your speed and downshift.
Remember, if you ride the brakes
excessively, they may overheat and
not work properly.
DBe careful when accelerating, up-
shifting, downshifting or braking on
a slippery surface. Sudden accelera-
tion or engine braking could cause
the vehicle to skid or spin.
DDo not continue normal driving
when the brakes are wet. If they are
wet, your vehicle will require a
longer stopping distance, and it
may pull to one side when the
brakes are applied. Also, the park-
ing brake will not hold the vehicle
securely.
NOTICE
zDo not depress the accelerator and
brake pedals at the same time dur-
ing driving. If the brake pedal is
depressed while driving with the ac-
celerator pedal depressed, driving
torque may be restrained.
zDo not use the accelerator pedal or
depress the accelerator and brake
pedals at the same time to hold the
vehicle on a hill.

Tips for driving in various
conditions

214STARTING AND DRIVING
Driving in the rain
Driving on a slippery road surface
Drive carefully when it is raining, because
visibility will be reduced, the windows may
become fogged−up, and the road will be
slippery.
DDrive carefully when it starts to rain,
because the road surface will be espe-
cially slippery.
DRefrain from high speeds when driving
on an expressway in the rain, because
there may be a layer of water between
the tires and the road surface, prevent-
ing the steering and brakes from oper-
ating properly.
CAUTION
DSudden braking, acceleration and
steering when driving on a slippery
road surface may cause tire slip-
page and reduce your ability to
control the vehicle, resulting in an
accident.
DSudden changes in engine speed,
such as sudden engine braking,
may cause the vehicle to skid, re-
sulting in an accident.
DAfter driving through a puddle,
lightly depress the brake pedal to
make sure that the brakes are func-
tioning properly. Wet brake pads
may prevent the brakes from func-
tioning properly. If the brakes on
only one side are wet and not func-
tioning properly, steering control
may be affected, resulting in an ac-
cident.
When encountering flooded roads
Do not drive on a road that has flooded
after heavy rain etc. Doing so may cause
serious damage to the vehicle.
NOTICE
Driving on a flooded road may cause
the engine to stall as well as cause
serious vehicle malfunctions such as
shorts in electrical components and
engine damage from water immersion.
In the event that you drive on a
flooded road and the vehicle is
flooded, be sure to have your Toyota
dealer check brake function, changes
in quantity and quality of engine oil,
transaxle fluid, etc. and lubricant con-
dition for the bearings and suspen-
sion joints (where possible) and the
function of all joints and bearings.

Winter driving tips
Make sure your coolant is properly pro-
tected against freezing.
Only use “Toyota Super Long Life Coolant”
or similar high quality ethylene glycol
based non−silicate, non−amine, non−nitrite,
and non−borate coolant with long−life hy-
brid organic acid technology. (Coolant with
long−life hybrid organic acid technology is
a combination of low phosphates and or-
ganic acids.)
See “Checking the engine coolant level”
on page 267 in Section 7−2 for details of
coolant type selection.
“Toyota Super Long Life Coolant” is a mix-
ture of 50% coolant and 50% deionized
water. This coolant provides protection
down to about−35_C(−31_F).
NOTICE
Do not use plain water alone.
Check the condition of the battery and
cables.
Cold temperatures reduce the capacity of
any battery, so it must be in top shape
to provide enough power for winter start-
ing. Section 7−3 tells you how to visually
inspect the battery. Any authorized Toyota
dealer or repairer, or another duly quali-
fied and equipped professional, will be
pleased to check the level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See page 264 in Section 7−2forrecom-
mended viscosity. Leaving a heavy sum-
mer oil in your vehicle during winter
months may make starting harder. If you
are not sure about which oil to use, call
any authorized Toyota dealer or repairer,
or another duly qualified and equipped
professional, they will be pleased to help.
Keep the door locks from freezing.
Squirt lock de−icer or glycerine into the
locks to keep them from freezing.Use a washer fluid containing an anti-
freeze solution.
This product is available at any authorized
Toyota dealer or repairer and most auto
parts stores or another qualified profes-
sional. Follow the manufacturer ’s direc-
tions for how much to mix with water.
NOTICE
Do not use engine antifreeze or any
other substitute because it may dam-
age your vehicle’s paint.
Do not use your parking brake when
there is a possibility it could freeze.
When parking, put the transmission into
“M(1)”, “E(1)” or “R” (multi−mode manual
transmission), or into first or reverse
(manual transmission) and block the rear
wheels. Do not use the parking brake,
snow or water accumulated in and around
the parking brake mechanism may freeze,
making it hard to release.
Keep ice and snow from accumulating
under the fenders.
Ice and snow built up under your fenders
can make steering difficult. During bad
winter driving, stop and check under the
fenders occasionally.
Depending on where you are driving,
we recommend you carry some emer-
gency equipment.
Some of the things you might put in the
vehicle are tire chains, a window scraper,
a bag of sand or salt, flares, a small
shovel, jumper cables, etc.

220IN CASE OF AN EMERGENCY
Before making these checks, make sure
you have followed the correct starting
procedure given in “How to start the
engine” on page 210 in Section 3 and that
you have sufficient fuel. Since your
vehicle is equipped with an engine
immobilizer system, also check whether
the other keys will start the engine. If
they work, your key may be broken. Have
the key checked at any authorized Toyota
dealer or repairer, or another duly
qualified and equipped professional. If
none of your keys work, there may be a
malfunction in the immobilizer system. Call
any authorized Toyota dealer or repairer,
or another duly qualified and equipped
professional. (See “Keys” on page 10 in
Section 1−2).
If the engine is not turning over or is
turning over too slowly—
1. Check that the battery terminals are
tight and clean.
2. If the battery terminals are O.K., switch
on the interior light.
3. If the light is out, dim or goes out
when the starter is cranked, the battery
is discharged. You may try jump start-
ing. See “(c) Jump starting” on page
221 for further instructions.
If the light is OK, but the engine still will
not start, it needs adjustment or repair.
Call any authorized Toyota dealer or re-
pairer, or another duly qualified and
equipped professional.
NOTICE
For manual transmission:
Do not pull−or push−start the ve-
hicle. It may damage the vehicle or
cause a collision when the engine
starts. Also the three−way catalytic
converter may overheat and become a
fire hazard.
If the engine turns over at its normal
speed but will not start—
1. Turn the engine switch to “ACC” or
“LOCK” and try starting the engine
again.
2. If the engine will not start, the engine
may be flooded because of repeated
cranking. See “(b) Starting a flooded
engine” on page 221 for further instruc-
tions.
3. If the engine still will not start, it needs
adjustment or repair. Call any autho-
rized Toyota dealer or repairer, or
another duly qualified and equipped
professional.
AYGO WE 99E37E11 02.18
If your vehicle will not start
(a) Simple checks

224IN CASE OF AN EMERGENCY
If the cause of the battery discharging is
not apparent (for example lights left on)
you should have it checked at any
authorized Toyota dealer or repairer, or
another duly qualified and equipped
professional.
If the first start attempt is not success-
ful...
Check that the clamp on the jumper
cables are tight. Recharge the discharged
battery with the jumper cables connected
for several minutes and restart your en-
gine in the normal way.
If another attempt is not successful, the
battery may be depleted. Have it checked
at any authorized Toyota dealer or repair-
er, or another duly qualified and equipped
professional.If your engine stalls while driving...
1. Reduce your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3. Try starting the engine again.
If the engine will not start, see “If your
vehicle will not start” on page 220 in this
Section.
CAUTION
If the engine is not running, the pow-
er assist for the brakes will not work
so braking will be much harder than
usual.
AYGO WE 99E37E11 02.18
If your engine stalls while
driving

IN CASE OF AN EMERGENCY225
If engine speed does not increase when
the accelerator pedal is depressed, there
may be a problem somewhere in the elec-
tronic throttle control system.
At this time, vibration may occur. Howev-
er, if you depress the accelerator pedal
more firmly and slowly, you can drive your
vehicle at low speeds. Have your Toyota
checked by any authorized Toyota dealer
or repairer, or another duly qualified and
equipped professional, as soon as pos-
sible.
Even if the abnormality of the electronic
throttle control system is corrected during
low speed driving, thesystem may not be
recovered until the engine is stopped and
the engine switch is turned to “ACC” or
“LOCK” position.
CAUTION
Be especially careful to prevent erro-
neous pedal operation.
If your high engine coolant temperature
warning light flashes to indicates over-
heating, if you experience a loss of
power, or if you hear a loud knocking
or pinging noise, the engine has prob-
ably overheated. You should follow this
procedure...
1. Pull safely off the road, stop the ve-
hicle and turn on your emergency
flashers. Put the transmission in “N”
(multi−mode manual transmission), or
neutral (manual transmission) and ap-
ply the parking brake. Turn off the air
conditioning if it is being used.
2. If coolant or steam is boiling out of the
radiator or reservoir, stop the engine.
Wait until the steam subsides before
opening the hood. If there is no coolant
boiling over or steam, leave the engine
running and make sure the electric
cooling fan is operating. If it is not,
turn the engine switch off.
CAUTION
To help avoid personal injury, keep
the hood closed until there is no
steam. Escaping steam or coolant is
a sign of very high pressure.
3. Look for obvious coolant leaks from the
radiator, hoses, and under the vehicle.
However, note that water draining from
the air conditioning is normal if it has
been used.
CAUTION
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts.

226IN CASE OF AN EMERGENCY
4. If the coolant is leaking, stop the en-
gine immediately. Call any authorized
Toyota dealer or repairer, or another
duly qualified and equipped profession-
al, for assistance.
5. If there are no obvious leaks, check
the coolant reservoir. If it is dry, add
coolant to the reservoir while the
engine is running. Fill it about half full.
For the coolant type see “Coolant type
selection” on page 267 in Section 7−2.
CAUTION
Do not attempt to remove the radiator
cap when the engine and radiator are
hot. Serious injury could result from
scalding hot fluid and steam blown
out under pressure.
6. After the engine coolant temperature
has cooled to normal, again check the
coolant level in the reservoir. If
necessary, bring it up to half full again.
Serious coolant loss indicates a leak in
the system. You should have it
checked as soon as possible at any
authorized Toyota dealer or repairer, or
another duly qualified and equipped
professional.1. Reduce your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place well away from
the traffic. Avoid stopping on the center
divider of a highway. Park on a level
spot with firm ground.
2. Stop the engine and turn on your
emergency flashers.
3.Manual transmission:
Firmly set the parking brake and put
the transmission in reverse.
Multi−mode manual transmission:
Securely apply the parking brake and
turn the engine switch “ON”. After the
operation, shift the shift lever to “M(1)”,
“E(1)” or “R”.
4. Have everyone get out of the vehicle
onthesideawayfromtraffic.
5. Read the following instructions thor-
oughly.
CAUTION
When jacking, be sure to observe the
following to help reduce the possibil-
ity of death or serious injury:
DFollow jacking instructions.
DDo not put any part of your body
under a vehicle supported by a
jack. Otherwise, death or serious
injury may occur.
DDo not start or run the engine while
your vehicle is supported by the
jack.
DStop the vehicle on a level firm
ground, firmly set the parking brake
and put the transmission in reverse.

Proper equipment will help ensure that
your vehicle is not damaged while being
towed. Commercial operators are generally
aware of the state/provincial and local
laws pertaining to towing.
Your vehicle could be damaged if it is
towed incorrectly. Although most operators
know the correct procedure, it is possible
to make a mistake. To avoid damage to
your vehicle, make sure the following pre-
cautions are observed. If necessary, show
this page to the tow truck driver.
TOWING PRECAUTIONS:
Use a safety chain system for all towing,
and abide by the state/provincial and local
laws. The wheels and axle on the ground
must be in good condition. If they are
damaged, use a towing dolly.
(a) Towing with wheel lift type truck
From front—Release the parking brake.
NOTICE
When lifting wheels, take care to en-
sure adequate ground clearance for
towing at the opposite end of the
raised vehicle. Otherwise, the bumper
and/or underbody of the towed vehicle
may be damaged during towing.
From rear—
DManual transmission:
We recommend using a towing dolly
under the front wheels. If you do not
use a towing dolly, place the engine
switch in the “ACC” position and put
the transmission in neutral.
DMulti−mode manual transmission:
We recommend using a towing dolly.
The towing dolly is set up under the
front wheels. If you do not use the
towing dolly (or if it is not available),
first turn the engine switch “ON” and
shift the shift lever to “N”. Make sure
that the gear is in the “N” position by
checking the gear position indicator.
Multi−mode manual transmission only:
After shifting the shift lever to the “N”
position, always make sure that the gear
is actually disengaged and is in neutral by
pushing the vehicle by hand or other
means. In case the gear can not be put
in neutral, turn the engine switch from the
“OFF” to “ON” position, and operate the
shift lever once from “N” to “E”, “M” or
“R”, then back to “N” again. Then turn the
engine switch from the “ON” to “OFF”
position. These procedures may help put
the gear in neutral. If the gear still can
not be put in neutral, you can not tow
without a towing dolly.
NOTICE
Do not tow with the key removed or
in the “LOCK” position when towing
from the rear without a towing dolly.
The steering lock mechanism is not
strong enough to hold the front
wheels straight.

Be sure to have the system checked any
authorized Toyota dealer or repairer, or
another duly qualified and equipped pro-
fessional, as soon as possible.
If you lose your keys
You can purchase a new key at any
authorized Toyota dealer or repairer, or
another duly qualified and equipped
professional, if you can give them the
key number and key.
Even if you lose only one key, contact
any authorized Toyota dealer or repairer,
or another duly qualified and equipped
professional, to make a new key. If you
lose all your keys, you cannot make new
keys; the whole engine immobilizersystem
must be replaced.
See the suggestion given in “Keys” on
page 10 in Section 1−2.
Wireless remote control key—
You can use the wireless remote control
system with the new key. Contact any
authorized Toyota dealer or repairer, or
another duly qualified and equipped pro-
fessional, for detailed information.
If your keys are locked in the vehicle and
you cannot get a duplicate, many autho-
rized Toyota dealers, repairers or other
duly qualified and equipped professionals
can still open the doors for you, using
their special tools. If you must break a
window to get in, we suggest breaking the
smallest side window because it is the
least expensive to replace. Be extremely
cautious to avoid cuts from the glass.
