SOLUTION
Check all wires and connectors. Make sure the
motor harness connector is tightly plugged into the battery,
and that there are no loose wires around the motors.
The built-in thermal fuse may "trip" and shut down operation
of the vehicle if the vehicle is overloaded or the driving
conditions too severe. The fuse will automatically reset
itself after approximately 25 seconds, allowing the vehicle
to resume normal operation. To avoid repeated automatic
shutdowns, do not overload the vehicle by exceeding the
130 lbs maximum weight capacity or by towing anything
behind the vehicle. Do not drive up hills or run into fixed
objects, which can cause the wheels to stop spinning while
power is still being supplied to the motors. If a thermal
fuse continually trips, contact your local Power Wheels
authorized service center.
Charge the battery. A new battery should have been
charged for at least 18 hours before using the vehicle for
the first time. After first-time use, recharge the battery for
at least 14 hours after each use. Never charge the
battery longer than 30 hours.
Check all wires and connectors. Make sure the motor
harness connector is tightly plugged into the battery, and
that the charger is plugged into the wall.
Make sure power flow to the wall outlet is "ON".
Do not charge the battery longer than 30 hours. If you
suspect that your battery is damaged as a result of
overcharging, contact your local Power Wheels
service center. They can test the battery for you.
Even with proper care, a rechargeable battery does not
last forever. Average battery life is 1 to 3 years depending
on vehicle use and use conditions. Replace only with a
Power Wheels ® 12 Volt Lead-Acid Rechargeable Battery.
Do not substitute parts.
The built-in thermal fuse may "trip" and shut down operation
of the vehicle if the vehicle is overloaded or the driving

The vehicle was pre-set to run only in low speed.
To allow the vehicle to run in low and high speed, you
must disconnect the High Speed Lock-Out. Follow the
instructions on page 13 to remove the High designed to
Speed Lock-Out screw.
It is possible that only one rear wheel may spin when both
rear wheels are raised off the ground and the vehicle is in
low speed. This does not necessarily indicate a problem.
Check for proper operation of the drive system by raising
the rear wheels off the ground and pressing the foot pedal.
If only one rear wheel spins, carefully press your hand on
the spinning wheel to slow it down. The other rear wheel
should begin to spin. If the other rear wheel does not begin
to spin, there may be a problem with the vehicle. Contact
your local Power Wheels authorized service center for
®
diagnosis and repair.
