CAUTION
n
If a safety system warning light does not come on
Should a safety system light such as ABS and the SRS airbag 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 your Toyota dealer
immediately if this occurs.
n Warning lights
Warning lights inform the driver of malfunctions in any of the
vehicle’s systems. ( →P. 293)
*: These lights turn on when the engine switch is turned to the ON
position to indicate that a system check is being performed. They will
turn off after the engine is started, or after a few seconds. There may
be a malfunction in a system if a light does not come on, or if the
lights do not turn off. Have the vehicle inspected by your Toyota
dealer.

When driving
Driving assist systems
nSounds and vibrations caused by the ABS
lA sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indi-
cate that a malfunction has occurred in this system.
l Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
n EPS operation sound
When the steering wheel operates, a motor sound (whirring sound) may be
heard.
This does not indicate a malfunction.
n Reduced effectiveness of EPS
The effectiveness of EPS 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 sys-
tem should return to normal within 10 minutes.
To help enhance driving safety a nd performance, the following sys-
tems operate automatically in res ponse to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavi ly when operating the vehicle.
nABS (Anti-lock Brake System) (if equipped)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface.
nEPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.

136 2-4. Using other driving systems
CAUTION
nThe ABS does not operate effectively when
lTires with inadequate gripping ability are used (such as excessively worn
tires on a snow covered road).
l The vehicle hydroplanes while driving at high speed on the wet or slick
road.
n Stopping distance when the ABS is ope rating on the wet or slick roads
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you in the following situ-
ations.
l When driving on dirt, gravel or snow-covered roads
l When driving with tire chains
l When driving over bumps in the road
l When driving over roads with potholes or uneven roads
n Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total
load capacity. In addition, make sure that the tires are inflated to the appro-
priate tire pressure level.
The ABS will not function correctly if different tires are fitted on the vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.
n Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause the system to malfunction.

When driving
l
In order to maintain engine braking efficiency, do not use the trans-
mission in D (automatic transmiss ion) or 5 (manual transmission).
l Due to the added load of the trailer, your vehicle’s engine may
overheat on hot days (at temperatures over 85°F [30°C]) when
driving up a long or steep grade. If the engine coolant temperature
gauge indicates overheating, immedi ately turn off the air condition-
ing (if in use), pull your vehicle off the road and stop in a safe spot.
( → P. 321)
l 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 (automatic transmission) or in 1 or R (manual
transmission). 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 blocks under both the vehicle and
trailer 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 1 or R (manual transmission) or P (automatic trans-
mission) and turn off the engine.
l When restarting after parking on a slope:
With the transmission in P (automatic transmission) or the
clutch pedal (manual transmission) depressed, start the
engine. On vehicles with an au tomatic transmission, be sure
to keep the brake pedal pressed.
Shift into a forward gear. If reversing, shift into R.
Release the parking brake (also brake pedal on vehicles with
an automatic transmission), and slowly pull or back away from
the wheel blocks. Stop and apply the brakes.
Have someone retrieve the blocks.

n Adjusting the Automatic Sound Levelizer (ASL)
When “ASL“ is selected, turni ng to the right changes the
“ASL level in the order of the “LOW”, “MID” and “HIGH”.
Turning to the left turns “ASL“ off.
ASL automatically adjusts the volu me and tone quality according to
the vehicle speed.

nAdding 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
n 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
nWhen 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
nIf 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.
n If you spill fluid
Be sure to wash it off with water to prevent damage to parts or paint.
