WARNING
■If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning light not
come on when you start the engine, this could mean that these systems are
not available to help protect you in an accident, which could result in death
or serious injury. Have the vehicle inspected by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional
immediately if this occurs.
NOTICE
■ To prevent damage to the engine and its components
The engine may be overheating if the high engine coolant temperature
warning light flashes or turns on. In this case, immediately stop the vehicle
in a safe place, and check the engine after it has cooled completely.
( P. 485)

■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
high engine coolant temperature warning light flashes or comes on,
turn the air conditioning off immediately, leave the road and stop the
vehicle in a safe place. ( P. 485)
■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
for Multidrives or 1 or R for manual transmissions.
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. 176)
■ 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 a trailer
when the tire installed is repaired with the emergency tire puncture repair
kit.

The coolant level is satisfactory if it is between the “FULL” and “LOW”
lines on the reservoir when the engine is cold.
Reservoir cap
“FULL” line
“LOW” line
If the level is on or below the “LOW” line, add coolant up to the “FULL”
line. ( P. 485)
■Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene
glycol based non-silicate, non-amine, non- nitrite, and non-borate coolant with
long-life hybrid organic acid technology.
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deion-
ized water. (Minimum temperature: -35 C [-31F])
For more details about coolant, contact any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
■ If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir caps, drain cock
and water pump.
If you cannot find a leak, have any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional test the cap and check for
leaks in the cooling system.
