Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropri-
ate to the prevailing weather conditions.
■ Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tem-
peratures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspect the level and specific grav-
ity of battery electrolyte.
● 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 chains
match the size of the tires.
■Before driving the vehicle
Perform the following according to the driving conditions.
●Do not try to forcibly open a window or move a wiper that is
frozen. 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 th e climate control system fan,
remove any snow that has accumulated on the air inlet vents
in front of the windshield.
● Remove any ice that has accumu lated on the vehicle chassis.
● Periodically check for and remove any excess ice or snow
that may have accumulated in the wheel well or on the
brakes.

Do-it-yourself ser vice precautions
If you perform maintenance yourself, be sure to follow the correct
procedures as given in these sections.
ItemsParts and tools
Battery condition ( P. 450)•Warm water
• Baking soda
• Grease
• Conventional wrench
(for terminal clamp bolts)
Brake fluid level ( P. 446)• FMVSS No.116 DOT 3 or SAE
J1703 brake fluid
• Rag or paper towel
• Funnel (used only for adding brake fluid)
Engine coolant level ( P. 444)• “Toyota Super Long Life Coolant”
or similar high quality ethylene
glycol based non-silicate, non-
amine, non-nitrite and non-borate
coolant with long-life hybrid
organic acid technology.
For the U.S.A.:
“Toyota Super Long Life
Coolant” is pre-mixed with 50%
coolant and 50% deionized
water.
For Canada:
“Toyota Super Long Life
Coolant” is pre-mixed with 55%
coolant and 45% deionized
water.
• Funnel (used only for adding engine coolant)

CAUTION
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 engine
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 or rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
● Take care because brake fluid can harm your hands or eyes and damage
painted surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with
clean water immediately.
If you still experience discomfort, see a doctor.
● Do not touch the engine compartment when the electric cooling fan is
operating.
The electric cooling fan may keep rotating for about 3 minutes even after
the engine switch is turned to the “LOCK” position.
With the engine switch in the “ON” position, the electric cooling fan may
automatically start to run if the air conditioning is on and/or the coolant
temperature is high. Be sure the engine switch is in the “LOCK” position
and that the electric cooling fan is completely stopped when working near
the electric cooling fan or radiator grille.
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.

“MAX”
“MIN”
CAUTION
■When the engine is hot
Do not touch the radiator or condenser as they may be hot and may cause
burns.
■ When the electric cooling fan is operating
Do not touch the engine compartment.
The electric cooling fan may keep rotating for about 3 minutes after the
engine switch is turned to the “LOCK” position.
With the engine switch in the “ON” position, the electric cooling fan may
automatically start to run if the air conditioning is on and/or the coolant tem-
perature is high. Be sure the engine switch is in the “LOCK” position and that

Maintenance and care
■
Adding fluid
Make sure to check the fluid type and prepare the necessary items.
Fluid type FMVSS No.116 DOT 3 or SAE J1703 brake fluid
Items Clean funnel
■ Brake fluid can absorb moisture from the air
Excess moisture in the fluid can cause a dangerous loss of braking effi-
ciency. Use only newly opened brake fluid.
CAUTION
■When filling the reservoir
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with clean
water immediately.
If you still experience discomfort, see a doctor.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious pro\
blem.
