the brightness level will also
change the brightness level of
night mode.
■ Outside temperature display
●In the following situations, the correct outside temperature ma y not be dis-
played, or the display may take longer than normal to change.
• When stopped, or driving at low speeds (less than 12 mph [20 k m/h])
• When the outside temperature has changed suddenly (at the entr ance/
exit of a garage, tunnel, etc.)
● The temperature range that can be displayed is from -40°F (-40° C) to 122°F
(50°C).
When the outside temperature drops below 37°F (3°C), the Low ou tside
temperature indicator will be displayed on the multi-informatio n display.
( P. 86)
● 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. 509)

Driving
●Due to the added load of the trailer, your vehicle’s engine may over-
heat on hot days (at temperatures over 85°F [30°C]) when drivin g
up a long or steep grade. If the Engine coolant temperature gau ge
overheating, immediately turn off the air conditioning (if in use), pull
your vehicle off the road an d stop in a safe spot. (P. 509)
● Always place wheel blocks under both the vehicle’s and the trai ler’s
wheels when parking. Apply the parking brake firmly, and put th e
transmission in P. Avoid parking on a slope, but if unavoidable , do
so only after perform ing the following:
Apply the brakes and keep them applied.
Have someone place wheel blocks under both the vehicle’s and
trailer’s wheels.
When the wheel blocks are in pl ace, release the brakes slowly
until the blocks absorb the load.
Apply the parking brake firmly.
Shift into P and turn off the engine.
● When restarting afte r parking on a slope:
With the transmission in P, start the engine. Be sure to keep t he
brake pedal pressed.
Shift into a forward gear. If reversing, shift into R.
Release the parking brake and brake pedal, and slowly pull or
back away from the wheel bloc ks. Stop and apply the brakes.
Have someone retrieve the blocks.

4-6. Driving tips
Winter driving tips
●Use fluids that are appropriate t o the prevailing outside tempera-
tures. • Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspec t the condition of the battery.
● Have the vehicle fitted with four snow tires or purchase a set of tire
chains for the front tires.
Ensure that all tires are the same size and brand, and that cha ins match
the size of the tires.
Perform the following accordi ng to the driving conditions:
● Do not try to forcibly open a window or move a wiper that is fr ozen.
Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to prevent it from freezing.
● To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
● Check for and remove any excess ic e or snow that may have accu-
mulated on the exterior lights, vehicle’s roof, chassis, around the
tires or on the brakes.
● Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.
Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a ma n-
ner appropriate to the prevailing weather conditions.

WARNING
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions:
■When working on the engine compartment:
● Keep hands, clothing and tools away from the moving fan and eng ine
drive belt.
● Be careful not to touch the engine, radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil and other fluids may also be hot.
● Do not leave anything that may burn easily, such as paper and r ags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel or t he bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
■ When working near the electric cooling fans or radiator grille
Be sure the engine switch is in the “LOCK” position (vehicles without a
smart key system) or off (vehicles with a smart key system). With the engine
switch in the “ON” position (vehicles without a smart key system) or IGNI-
TION ON mode (vehicles with a smart key system), the electric cooling fans
may automatically start to run if the air conditioning is on an d/or the coolant
temperature is high. ( P. 415)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc.
from getting in your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.
