When driving
L/C200_EE (OM60G38E)
CAUTION
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 may enter the vehicle, lead-
ing 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.
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 braking distance
becomes longer.
Do not drive your vehicle with only a single brake system. Have your
brakes fixed immediately.

When driving
L/C200_EE (OM60G38E)
Parking brake
Usage in winter time
P. 319
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.
Sets the parking brake
Fully set the parking brake
while depressing the brake
pedal.
Releases the parking brake
Slightly raise the lever and
lower it completely while press-
ing the button.

206 2-2. Instrument cluster
L/C200_EE (OM60G38E)
Instrument cluster light control
The brightness of the instrument cluster light can be adjusted.
Darker
Brighter
The meters and display illuminate when
The “ENGINE START STOP” switch is in IGNITION ON mode.
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. 634)
While driving
When the voltmeter indicates more than 19 V or less than 9 V, the battery
may be malfunctioning. Have your vehicle checked at any authorized
Toyota dealer or repairer, or another duly qualified and equipped
professional.
When the engine oil pressure gauge does not work properly, immediately
stop the engine and contact any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional.

268 2-4. Using other driving systems
L/C200_EE (OM60G38E)
Function limitations
Crawl Control
In the following situations, brake control can be used to drive downhill at
a constant speed. However, engine control is not available when driving
uphill at a constant speed.
• When switched to second start mode.
In the following situation, engine control and brake control will stop tem-
porarily. In this event, the Crawl Control indicator will flash.
• When the vehicle speed exceeds approximately 25 km/h (15 mph).
Turn Assist function
In the following situations, the Turn Assist function will stop temporarily. In
this event, the Turn Assist indicator will flash.
When the vehicle speed exceeds approximately 10km/h (6 mph).
When the shift lever is moved to “R”.
When the Crawl Control system is operated continuously
If Crawl Control is used continuously for a long time, the buzzer will
sound, a malfunction notification will be displayed on the multi-informa-
tion display, the Crawl Control indicator will go off, and Crawl Control will
be temporarily inoperable as a result of the brake system overheating. In
this event, stop the vehicle immediately in a safe place, and allow the
brake system to cool down sufficiently until the “TRC OFF” on the multi-
information display go off. (In the meantime, normal driving is possible.)
If Crawl Control is used continuously for a long time, the buzzer will
sound, the system will be temporarily canceled, and a malfunction notifi-
cation will be displayed on the multi-information display as a result of the
automatic transmission system overheating. Stop the vehicle in a safe
place until the display goes off.

332 2-5. Driving information
L/C200_EE (OM60G38E)Transmission information
To maintain engine braking efficiency, when using engine braking,
do not put the transmission in “D”.
Transmission shift range position must be in “5” in the “S” mode.
If the engine overheats...
Towing a loaded trailer up a long steep incline in temperatures
exceeding 30C (85F) may result in the engine overheating. If the
engine coolant temperature gauge indicates that the engine is
overheating, turn the air conditioning off immediately, leave the
road and stop the vehicle in a safe place. (P. 634)
When parking the vehicle
Always place wheel chocks under the wheels of both the vehicle
and trailer. Firmly set the parking brake and shift the shift lever to
“P”.
CAUTION
Follow all the precautions described in this section. Failure to do so could
cause an accident resulting in death or serious injury.
Trailer towing precautions
When towing, make sure that none of the weight limits are exceeded.
(P. 324)
Vehicle speed in towing
Observe the legal maximum speeds for trailer towing.
Before descending hills or long declines
Reduce speed and downshift. However, never downshift suddenly while
descending steep or long downhill grades.
Operation of the brake
Do not hold the brake pedal depressed often or for long periods.
Doing so may result in the brake overheating or reduce braking effects.

CAUTION
Burns
Only appropriately qualified and capable non-impaired persons should
operate the vehicle. However, care should be taken to prevent injury if
anyone in the following categories comes into contact with the steering
wheel when the heated steering wheel is on:
• Babies, small children, the elderly, the sick and the disabled
• Persons with sensitive skin
• Persons who are fatigued
• Persons who have taken alcohol or drugs that induce sleep (sleeping
drugs, cold remedies, etc.)
Do not use the heated steering wheel more than necessary. Doing so may
cause minor burns or overheating.
NOTICE
To prevent battery discharge
Turn the switch off when the engine is not running.

CAUTION
Burns
Use caution when seating the following persons in a seat with the seat
heater on to avoid the possibility of burns:
• Babies, small children, the elderly, the sick and the physically chal-
lenged
• Persons with sensitive skin
• Persons who are fatigued
• Persons who have taken alcohol or drugs that induce sleep (sleeping
drugs, cold remedies, etc.)
Do not cover the seat with anything when using the seat heater.
Using the seat heater with a blanket or cushion increases the temperature
of the seat and may lead to overheating.
Do not use the seat heater more than necessary. Doing so may cause
minor burns or overheating.
NOTICE
To prevent damage to the seat heaters and ventilators
Do not put heavy objects that have an uneven surface on the seat and do
not stick sharp objects (needles, nails, etc.) into the seat.
To prevent battery discharge
Turn the seat heaters and ventilators off and observe that the indicator light
is off when the engine is not running.

When trouble arises
L/C200_EE (OM60G38E)
Overheating
If you observe the following, your vehicle may be overheating.
The engine coolant temperature gauge enters the red zone or a loss of
power is experienced.
Steam is coming from under the hood.
Add engine coolant if neces-
sary.
Water can be used in an emer-
gency if engine coolant is
unavailable.
(P. 654)
Have the vehicle checked at the nearest authorized Toyota dealer
or repairer, or another duly qualified and equipped professional as
soon as possible.
