■Outside temperature display
●In the following situations, the cor-
rect outside temperature may not
be displayed, or the display may
take longer than normal to
change:
• When stopped, or driving at low
speeds (less than 16 mph [25
km/h])
• When the outside temperature
has changed suddenly (at the
entrance/exit of a garage, tunnel,
etc.)
●When “--” or “E” is displayed, the
system may be malfunctioning.
Take your vehicle to your Toyota
dealer.
■Liquid crystal display
 P. 8 7
■Changing the display
Press the display change button
until the desired item is dis-
played.
■Display items
 Odometer
Displays the total distance the vehi-
cle has been driven.
Trip meter A/Trip meter B
Displays the distance the vehicle
has been driven since the meter
was last reset. Trip meters A and B
can be used to record and display
WARNING
■The information display at
low temperatures
Allow the interior of the vehicle to
warm up before using the liquid
crystal information display. At
extremely low temperatures, the
information display monitor may
respond slowly, and display
changes may be delayed.
For example, there is a lag
between the driver’s shifting and
the new gear number appearing
on the display. This lag could
cause the driver to downshift
again, causing rapid and exces-
sive engine braking and possibly
an accident resulting in death or
injury.
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 maxi-
mum engine speed.
●The engine may be overheating
if the engine coolant tempera-
ture gauge is in the red zone
(H). In this case, immediately
stop the vehicle in a safe place,
and check the engine after it
has cooled completely.

1404-1. Before driving
COROLLA_U
WARNING
●Do not touch the exhaust pipes
while the engine is running or
immediately after turning the
engine off.
Doing so may cause burns.
■When taking a nap in the vehi-
cle
Always turn the engine off. Other-
wise, if you accidentally move the
shift lever or depress the acceler-
ator pedal, this could cause an
accident or fire due to engine
overheating. Additionally, if the
vehicle is parked in a poorly venti-
lated area, exhaust gases may
collect and enter the vehicle, lead-
ing to death or a serious health
hazard.
■When braking
●When the brakes are wet, drive
more cautiously.
Braking distance increases
when the brakes are wet, and
this 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 brake booster device does
not operate, do not follow other
vehicles closely and avoid hills
or sharp turns that require brak-
ing.
In this case, braking is still pos-
sible, but the brake pedal
should be depressed more
firmly than usual. Also, the brak-
ing distance will increase. Have
your brakes fixed immediately.
●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.
●The brake system consists of 2
individual hydraulic systems; if
one of the systems fails, the
other will still operate. In this
case, the brake pedal should be
depressed more firmly than
usual and the braking distance
will increase. Have your brakes
fixed immediately.
■If the vehicle becomes stuck
Do not spin the wheels exces-
sively when a driven wheel is up
in the air, or the vehicle is stuck in
sand, mud, etc. This may damage
the driveline components or pro-
pel the vehicle forward or back-
ward, causing an accident.
NOTICE
■When driving the vehicle
(vehicles with a continuously
variable transmission)
●Do not depress the accelerator
and brake pedals at the same
time during driving, as this may
restrain the engine output.
●Do not use the accelerator
pedal or depress the accelera-
tor and brake pedals at the
same time to hold the vehicle on
a hill.
■When driving the vehicle
(vehicles with a manual trans-
mission)
●Do not depress the accelerator
and brake pedals at the same
time during driving, as this may
restrain the engine output.
●Do not shift gears unless the
clutch pedal is fully depressed.
After shifting, do not release the
clutch pedal abruptly. Doing so
may damage the clutch, trans-
mission and gears.

■Steering lock function
●After turning the engine switch off
and opening and closing the
doors, the steering wheel will be
locked due to the steering lock
function. Operating the engine
switch again automatically can-
cels the steering lock.
●When the steering lock cannot be
released, “Push Engine Switch
while Turning Steering Wheel in
Either Direction” will be displayed
on the multi-information display.
Press the engine switch shortly
and firmly while turning the steer- ing wheel left and right.
●To prevent the steering lock motor
from overheating, operation of the
motor may be suspended if the
engine is turned on and off repeat-
edly in a short period of time. In
this case, refrain from operating
the engine switch. After about 10
seconds, the steering lock motor
will resume functioning.
■Electronic key battery
 P.458
■Operation of the engine switch
●If the switch is not pressed shortly
and firmly, the engine switch
mode may not change or the
engine may not start.
●If attempting to restart the engine
immediately after turning the
engine switch off, the engine may
not start in some cases. After turn-
ing the engine switch off, please
wait a few seconds before restart-
ing the engine.
■Customization
If the smart key system has been
deactivated in a customized setting,
refer to P.513.
WARNING
■When starting the engine
Always start the engine while sit-
ting in the driver’s seat. Do not
depress the accelerator pedal

WARNING
■When parking the vehicle
Do not leave a child in the vehicle
alone. The parking brake may be
released unintentionally and there
is the danger of the vehicle mov-
ing that may lead to an accident
resulting in death or serious injury.
■Parking brake switch
Do not set any objects near the
parking brake switch.
Objects may interfere with the
switch and may lead the parking
brake to unexpectedly operate.
NOTICE
■When parking the vehicle
Before you leave the vehicle, set
the parking brake, shift the shift
lever to P (continuously variable
transmission) or N (manual trans-
mission) and make sure that the
vehicle does not move.
■When the system malfunc-
tions
Stop the vehicle in a safe place
and check the warning messages.
■When the parking brake can-
not be released due to a mal-
function
Driving the vehicle with the park-
ing brake set will lead to brake
components overheating, which
may affect braking performance
and increase brake wear.
Have the vehicle inspected by
your Toyota dealer immediately if
this occurs.
Brake Hold*
 Continuously variable trans-
mission
The brake hold system keeps the
brake applied when the shift lever
is in D, B (vehicles without paddle
shift switches), M (vehicles with
paddle shift switches) or N with
the system on and the brake
pedal has been depressed to
stop the vehicle. The system
releases the brake when the
accelerator pedal is depressed
with the shift lever in D, B (vehi-
cles without paddle shift
switches) or M (vehicles with
paddle shift switches) to allow
smooth start off.
Manual transmission
The brake hold system keeps the
brake applied when the shift lever
is in a forward driving position or
N with the system on and the
brake pedal has been depressed
to stop the vehicle. The system
releases the brake when the
accelerator pedal is depressed
with the shift lever in a forward
driving position to allow smooth
start off.
