Electronic Brake Force Distribution System Warning
If the electronic brake force distribution control unit deter-
mines that some components are operating incorrectly,
the control unit may illuminate the brake system warning
light and the ABS warning light simultaneously. The prob-
lem is likely to be the electronic brake force distribution
system.
Charging System Warning Light
If the warning light illuminates while driving, it indicates a
malfunction of the alternator or of the charging system.
Drive to the side of the road and park off the right-of-way.
Consult your Toyota dealer.
Engine Oil Warning LightThis warning light indicates low engine oil pressure.
If the light illuminates or the warning indication is dis-
played while driving:
Drive to the side of the road and park off the right-of-
way on level ground.
Turn off the engine and wait 5 minutes for the oil to
drain back into the oil pan.
Inspect the engine oil level P. 424. If it’s low, add the
appropriate amount of engine oil while being careful
not to overfill.
Start the engine and check the warning light.
If the light remains illuminated even though the oil level is
normal or after adding oil, stop the engine immediately
and have your vehicle towed to your Toyota dealer.

■Power Steering Malfunction Indicator Light
●If the indicator light illuminates/flashes, the power steering will not operate
normally. If this happens, the steering wheel can still be operated, however,
the operation may feel heavy compared to normal, or the steering wheel
could vibrate when turning.
● Repeatedly jerking the steering wheel left and right while the vehicle is
stopped or moving extremely slowly will cause the power steering system to
go into protective mode which will make the steering feel heavy, but this
does not indicate a problem. If this occurs, park the vehicle safely and wait
several minutes for the system to return to normal.
WARNING
■Do not drive with the brake system warning light illuminated. Contact
your Toyota dealer to have the brakes inspected as soon as possible
Driving with the brake system warning light illuminated is dangerous. It indi-
cates that your brakes may not work at all or that they could completely fail
at any time. If this light remains illuminated, after checking that the parking
brake is fully released, have the brakes inspected immediately.
In addition, the effectiveness of the braking may diminish so you may need
to depress the brake pedal more strongly than normal to stop the vehicle.
■ Do not drive with both the ABS warning light and brake warning light
illuminated. Have the vehicle towed to your Toyota dealer to have the
brakes inspected as soon as possible
Driving when the brake system warning light and ABS warning light are illu-
minated simultaneously is dangerous.
When both lights are illuminated, the rear wheels could lock more quickly in
an emergency stop than under normal circumstances.
NOTICE
■ Charging System Warning Light
Do not continue driving when the charging system warning light is illumi-
nated because the engine could stop unexpectedly.
■ Engine Oil Warning Light
● Do not run the engine if the oil pressure is low. Otherwise, it could result in
extensive engine damage.
● Do not run the engine if the oil level is low. Otherwise, it could result in
extensive engine damage.
■ High Engine Coolant Temperature Warning Light
Do not drive the vehicle with the high engine coolant temperature warning
light illuminated. Otherwise, it could result in damage to the engine.

7-7. Tire Information (U.S.A.)
GCWR (Gross Combination Weight Rating) is the maximum allowable
weight of the vehicle - including all cargo and passengers - that the
vehicle can handle without risking damage. The GCW must never
exceed the GCWR.
WARNING
■Do not tow a trailer with this vehicle
Towing a trailer with this vehicle is dangerous because it has not been
designed to tow a trailer and doing so will affect the drive system which
could result in vehicle damage.
■Overloaded Vehicle
Overloading a vehicle is dangerous. The results of overloading can
have serious consequences in terms of passenger safety. Too much
weight on a vehicle’s suspension system can cause spring or shock
absorber failure, brake failure, handling or steering problems, irregular
tire wear, tire failure or other damage.
Overloading makes a vehicle harder to drive and control. It also
increases the distance requ ired for stopping. In cases of serious over-
loading, brakes can fail completely, particularly on steep grades. The
load a tire will carry safely is a combin ation of the size of the tire, its load
range, and corresponding inflation pressure.
Never overload the vehicle and always observe the vehicle’s weight rat-
ings from the vehicle’s Safety Cert ification and Tire and Load Informa-
tion labels.
■Never Exceed Axle Weight Rating Limits
Exceeding the Safety Certification Label axle weight rating limits is dan-
gerous and could result in death or serious injury as a result of substan-
dard vehicle handling, performanc e, engine, transmission and/or
structural damage, serious damage to the vehicle, or loss of control.
Always keep the vehicle within the axle weight rating limits.
■Never Exceed GVWR or GAWR Specifications
Exceeding the GVWR or the GAWR sp ecified on the certification label is
dangerous. Exceeding any vehicle rating limitation could result in a seri-
ous accident, injury, or damage to the vehicle.
Do not use replacement tires with lower load carrying capacities than
the originals because they may lo wer the vehicle’s GVWR and GAWR
limitations. Replacement tires with a higher limit than the originals do
not increase the GVWR and GAWR limitations. Never exceed the
GVWR or the GAWR specified on the certification label.
