■The meters and display illuminate when
Vehicles without a smart key system
The engine switch is in the “ON” position.
Vehicles with a smart key system
The engine switch is in IGNITION ON mode.
■Brightness of the meters (day mode and night mode)
●The brightness of the meters is changed between day mode and night
mode.
• Day mode: When the tail lights are off or when the tail lights are on but
the surrounding area is bright
• Night mode: When the tail lights are on and the surrounding area is dark
●When in night mode, the brightness will be reduced slightly unless the
meters are set to the maximum brightness level.
■Outside temperature display
In 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 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.
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 engine coolant temperature 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. (→P. 534)

1904-1. Before driving
CAMRY_U (01999-06122)
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When the vehicle is parked
●Always apply the parking brake, shift the shift lever to P, stop the engine
and lock the vehicle.
Do not leave the vehicle unattended while the engine is running.
If the vehicle is parked with the shift lever in P but the parking brake is not
set, the vehicle may start to move, possibly leading to an accident.
●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 vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift
lever or depress the accelerator pedal, this 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, leading 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 power brake assist function does not operate, do not follow other
vehicles closely and avoid hills or sharp turns that require braking.
In this case, braking is still possible, but the brake pedal should be
depressed more firmly than usual. Also, the braking 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.

■Auto power off function
If the vehicle is left in ACCESSORY mode for more than 20 minutes or IGNI-
TION ON mode (with the engine is not running) for more than an hour with
the shift lever in P, the engine switch will automatically turn off. However, this
function cannot entirely prevent battery discharge. Do not leave the vehicle
with the engine switch in ACCESSORY or IGNITION ON mode for long peri-
ods of time when the engine is not running.

■If the engine does not start
●The engine immobilizer system may not have been deactivated. (→P. 71)
Contact your Toyota dealer.
●Check that the shift lever is securely set in P. The engine may not start if the
shift lever is displaced out of P.
■Steering lock
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 cancels the steering lock.
■When the steering lock cannot be released
■Steering lock motor overheating prevention
To prevent the steering lock motor from overheating, the motor may be sus-
pended if the engine is turned on and off repeatedly in a short period of time.
In this case, refrain from operating the engine. After about 10 seconds, the
steering lock motor will resume functioning.
■When a message requesting the smart key system be inspected is dis-
played on the multi-information display
The system may be malfunctioning. Have the vehicle inspected by your
Toyota dealer immediately. A message informing the driver that the
steering wheel is locked will be displayed
on the multi-information display.
Check that the shift lever is set in P. Press
the engine switch while turning the steer-
ing wheel left and right.

CAMRY_U (01999-06122)■Sounds and vibrations caused by the ABS, brake assist, VSC, TRAC and
hill-start assist control systems
●A sound may be heard from the engine compartment when the brake pedal
is depressed repeatedly, when the engine is started or just after the vehicle
begins to move. This sound does not indicate that a malfunction has
occurred in any of these systems.
●Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard also after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
■Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:
●When the engine switch is turned off
●If only the TRAC system is turned off, the TRAC will turn on when vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases.
■Secondary Collision Brake operating conditions
The vehicle speed is approximately 6 mph (10 km/h) or more and the airbag
sensor detects a collision. (The Secondary Collision Brake will not operate
when the vehicle speed is below approximately 6 mph [10km/h].)
■Secondary Collision Brake automatic cancellation
The Secondary Collision Brake is automatically canceled in the following situ-
ations:
●The vehicle speed drops below approximately 6 mph (10 km/h)
●A certain amount of time elapses during operation
●The accelerator pedal is depressed a large amount
■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.
