■When driving the vehicle
Accelerate the vehicle slowly and drive at a reduced speed suit-
able to road conditions.
■ When parking the vehicle
Park the vehicle and move the shift lever to P without setting the
parking brake. The parking brak e may freeze up, preventing it
from being released.
■ Refueling (Flex-fuel vehicles)
Observe the following precautions when switching fuels, in order
to maintain starting and driving performance.
●Do not change fuels when the fuel level is 1/4 or less.
● Always add at least 2.6 gal. (10 L) of fuel.
● After fulling up with fuel, warm up the engine or drive the vehi-
cle for at least 5 minutes or 7 miles (11 km).
● Do not accelerate rapidly immediately after refueling.

250 2-5. Driving information
●Crosswinds and rough roads will adversely affect handling of your
vehicle and trailer, causing sway . Periodically check the rear to
prepare for being passed by large trucks or buses, which may
cause your vehicle and trailer to sway. If swaying occurs, firmly grip
the steering wheel, reduce speed immediately but gradually, and
steer straight ahead. Never increase speed. If you make no
extreme correction with the stee ring or brakes, your vehicle and
trailer will stabilize.
● Take care when passing other v ehicles. Passing requires consider-
able distance. After passing a vehi cle, do not forget the length of
your trailer, and be sure you hav e plenty of room before changing
lanes.
● In order to maintain engine braking efficiency when driving on a
long steep downgrade, do not use the transmission in D.
Transmission shift range position must be in 5 in the S mode (6-
speed models) or in 4 in the S mode (5-speed models).
● Due to the added load of the trailer, your vehicle’s engine may
overheat on hot days (at temper atures over 85°F [30°C]) when
driving up a long or steep grade. If the engine coolant temperature
gauge indicates overheating, immediately turn off the air condition-
ing (if in use), pull your vehicle off the road and stop in a safe spot.
( P. 550)
● Always place wheel blocks under both the vehicle and the trailer
wheels when parking. Apply the parking brake firmly, and put the
transmission in P. Avoid parking on a slope, but if unavoidable, do
so only after performing the following:
Apply the brakes and keep them applied.
Have someone place wheel bloc ks under both the vehicle and
trailer wheels.
When the wheel blocks are in place, release the brakes slowly
until the blocks absorb the load.
Apply the parking brake firmly.

When driving
Shift into P and turn off the engine.
● When restarting after parking on a slope:
With the transmission in P, start the engine. Be sure to keep
the brake pedal pressed.
Shift into D or R (if reversing).
Release the parking brake and brake pedal, and slowly pull or
back away from the wheel blocks. Stop and apply the brakes.
Have someone retrieve the blocks.
■ Service connector for towing br ake controller (with towing package)
Your vehicle is equipped with a service
connector for the trailer brake controller
as shown.
Access the service connector.
Remove the scuff plate.
Remove the clip (screw type)
and trim board.

■Before towing
Check that the following conditions are met:
●Ensure that your vehicle’s tires are properly inflated. ( P. 567)
● Trailer tires should be inflated according to the trailer manufacturer’s rec-
ommendation.
● All trailer lights work to be legal.
● All lights work each time you connect them.
● The trailer ball is set up at the proper height for the coupler on the t\
railer.
● The vehicle remains level when a loaded or unloaded trailer is hitched.
Do not drive if the vehicle is not level, and check for improper tongue
load, overloading, worn suspension, or other possible causes.
● The trailer cargo is securely loaded.
● The rear view mirrors conform to all applicable federal, state/provincial or
local regulations. If they do not, install rear view mirrors appropriate for
towing purposes.
● Depress TOW/HAUL button (if equipped)
■ When connecting and disconnecting a trailer
Set the electronically modulated air suspension system to MAN., or turn off
the engine, when the system is in N mode. (if equipped)
■ AVS (adaptive variable suspension system) (if equipped)
The suspension can be switched for improvement in driveability. ( P. 213)
■ Break-in schedule
If your vehicle is new or equipped with any new power train components
(such as an engine, transmission, differential and wheel bearing), Toyota
recommends that you do not tow a trailer until it has been driven for over 500
miles (800 km).
However, avoid full throttle acceleration.
■ Maintenance
●If you tow a trailer, your vehicle will require more frequent maintenance
due to the additional load. (See “Scheduled Maintenance Guide” or
“Owner’s Manual Supplement”.)
● Retighten the fixing bolts of the towing ball and bracket after approxi-
mately 600 miles (1000 km).

■When outside temperature approaches 32 F (0 C)
The air conditioning system may not operate even when is pressed.
■ When the indicator on
flashes
Press
and turn off the air conditioning system before turning it on
once more. There may be a problem in the air conditioning system if the indi-
cator continues to flash. Turn the air conditioning system off and have it
inspected by your Toyota dealer.
CAUTION
■ To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather. The
difference between the temperature of the outside air and that of the wind-
shield can cause the outer surface of the windshield to fog up, blocking your
vision.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the
engine is stopped.
