■The meters and display illuminate when
Vehicles without a smart entry & start system
The engine switch is in the “ON” position.
Vehicles with a smart entry & start system
The engine switch is in IGNITION ON mode.
■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 15 km/h [9 mph])
• When the outside temperature has changed suddenly (at the entrance/
exit of a garage, tunnel, etc.)
●If “ ” is displayed continuously, the system may be malfunctioning. Take
your vehicle to any authorized Toyota dealer or repairer, or another duly
qualified and equipped professional.
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.
●In the following situations, the engine may be overheating. In this case,
immediately stop the vehicle in a safe place, and check the engine after it
has cooled completely. (P. 600)
• 3-ring meter: The high engine coolant temperature warning light comes

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■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 brake booster 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.
NOTICE
■When driving the vehicle (vehicles with a Multidrive)
●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 accelerator and brake
pedals at the same time to hold the vehicle on a hill.

Driving
■Important points regarding stability
Vehicle movement resulting from uneven road surfaces and strong
crosswinds will affect handling. The vehicle may also be rocked by
passing buses or large trucks. Frequently check behind when mov-
ing alongside such vehicles. As soon as such vehicle movement
occurs, immediately start to decelerate smoothly by slowly applying
the brakes. Always steer the vehicle straight ahead while braking.
■Passing other vehicles
Consider the total combined length of your vehicle and trailer and
ensure that the vehicle-to-vehicle distance is sufficient before exe-
cuting lane changes.
■Transmission information
Multidrive
To maintain engine braking efficiency and charging system perfor-
mance when using engine braking, do not use the transmission in
D, must be in M and select gear step 4 or lower. (P. 226)
Manual transmission
Refrain from driving in 6th gear to maintain the effectiveness of
engine braking and to maintain charging system performance.
■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 over-
heating, turn the air conditioning off immediately, leave the road and
stop the vehicle in a safe place. (P. 600)
■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
(Multidrive) and 1 or R (manual transmission).

WARNING
Follow all the instructions 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. 200)
■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 pedal
Do not hold the brake pedal depressed often or for long periods of time.
Doing so may result in the brake overheating or reduce braking effects.
■To avoid accident or injury
●Vehicles with a cruise control: Do not use cruise control when you are tow-
ing.
●Vehicles with a compact spare tire: Do not tow a trailer when the compact
spare tire is installed on your vehicle.
●Vehicles with an emergency tire puncture repair kit: Do not tow the vehicle
when the tire installed is repaired with the emergency tire puncture repair
kit.
NOTICE
■Do not directly splice trailer lights
Directly splicing trailer lights may damage your vehicle’s electrical system
and cause a malfunction.

■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 TRC and VSC systems
After turning the TRC and VSC systems off, the systems will be automatically
re-enabled in the following situations:
●Vehicles without a smart entry & start system: When the engine switch is
turned to the “LOCK” position
Vehicles with a smart entry & start system: When the engine switch is turned
off
●If only the TRC system is turned off, the TRC will turn on when vehicle
speed increases
If both the TRC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases.
■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.
■Operating conditions of hill-start assist control
When the following four conditions are met, the hill-start assist control will
operate:
●Vehicles with a Multidrive: The shift lever is in a position other than P or N
(when starting off forward/backward on an upward incline).
●Vehicles with a manual transmission: The shift lever is in a position other
than R when starting off forward on an upward incline or in R when starting
off backward on an upward incline.
●The vehicle is stopped.
●The accelerator pedal is not depressed.
●The parking brake is not engaged.
■Automatic system cancelation of hill-start assist control
The hill-start assist control will be canceled in any of the following situations:
●Vehicles with a Multidrive: The shift lever is shifted to P or N.
●Vehicles with a manual transmission: The shift lever is shifted to R when
starting off forward on an upward incline or from R when starting off back-
ward on an upward incline.
●The accelerator pedal is depressed.
●The parking brake is engaged.
●Approximately 2 seconds elapse after the brake pedal is released.
