240 STARTING AND OPERATING

WARNING!
Significant over or under inflation of tires can lead to
loss of braking effectiveness.
The Anti-Lock Brake System conducts a low-speed self-
test at about 12 mph (20 km/h). If you have your foot
lightly on the brake while this test is occurring you may
feel slight pedal movement. The movement can be more
apparent on ice and snow. This is normal.
The Anti-Lock Brake System pump motor runs during
the self-test at 12 mph (20 km/h) and during an ABS stop.
The pump motor makes a low humming noise during
operation, which is normal.
WARNING!
Pumping of the Anti-Lock Brakes will diminish their
effectiveness and may lead to an accident. Pumping
makes the stopping distance longer. Just press firmly
on your brake pedal when you need to slow down or
stop.

WARNING!
Overloading of your tires is dangerous. Overloading
can cause tire failure, affect vehicle handling, and
increase your stopping distance. Use tires of the
recommended load capacity for your vehicle. Never
overload them.
TIRES Ð GENERAL INFORMATION
Run Flat Tires
This vehicle is equipped with run flat tires. Although the
tires are designed with a ªrun flatº feature that allows the
vehicle to be driven about 50 miles (80 km) at 55 mph (88
km/h), immediate service should be obtained.
WARNING!
Do not exceed 50 mph (80 km/h) if the ªTire Pressure
Monitoring Telltale Lightº is illuminated. Vehicle
handling and braking may be reduced. You could
have an accident and be severely or fatally injured.
NOTE:The ªrun flatº feature eliminates the need for a
spare tire or jack. This vehicle is not equipped with either
a spare tire or jack.
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Three primary
areas are affected by improper tire pressure:
