GENERAL INFORMATION
To ensure trouble-free vehicle performance, it is very important to follow an established preventive mainte-
nance program. Regular and consistent vehicle maintenance can prevent vehicle downtime and expensive
repairs that can result from neglect. Any vehicle not functioning correctly should be removed from use until it
is properly repaired. This will prevent further damage to the vehicle and avoid the possibility of injury due to
unsafe conditions.
Contact your local Club Car distributor/dealer to perform all repairs and semiannual and annual periodic ser-
vice.
PERIODIC SERVICE SCHEDULE
ý WARNING
• Service, repairs, and adjustments must be made per instructions in the appropriate
maintenance and service manual and this supplement.
NOTE: If the vehicle is constantly subjected to heavy use or severe operating conditions, the preventive
maintenance procedure should be performed more often than recommended in the periodic ser-
vice and lubrication schedules.
Both the Periodic Service Schedule and the Periodic Lubrication Schedule must be followed to
keep vehicle in optimum operating condition.

SECTION 11 – ELECTRICAL SYSTEM AND
TESTING
ý DANGER
• See General Warning, Section 10, Page 10-1.
ý WARNING
• See General Warning, Section 10, Page 10-1.
GENERAL INFORMATION
The IQ Plus vehicle uses a 48-volt electrical system that is powered by eight 6-volt lead-acid batteries and
includes an onboard computer. The IQ Plus vehicle uses a shunt-wound 3.7 hp motor and includes several
additional features.
• Shunt-Wound Motor: The shunt-wound motor, unlike a series motor, is designed so that the speed
controller is able to vary the amount of current passing through the field coils independently from the
current passing through the armature.
• Motor Braking: Under certain conditions a shunt-wound motor also has the ability to act as an electri-
cal brake to slow the vehicle. There are three features of the IQ Plus electrical system which will acti-
vate the motor braking function: Walk Away Braking, Pedal Down Motor Braking, and Pedal Up Motor
Braking (adjustable with the IQDM-P handset).
• Walk Away Braking: the walk away braking feature will prevent the vehicle from rolling at more than 1
or 3 mph (1.5 or 4.8 km/h) unless the accelerator is pressed. This prevents the possibility of a parked
vehicle (with the park brake disengaged) rolling away too fast to be overtaken on foot. If the walk away
braking function remains engaged for two seconds or more, a warning buzzer will sound to alert the
driver that motor braking has been activated.
ý WARNING
• Walk away braking will not limit vehicle speed to 1 mph (1.6 km/h) on very steep grades. Do
not operate vehicle on slopes exceeding 20% grades.
• Pedal Down Motor Braking: This feature helps to control vehicle downhill speed. Motor braking is
activated when the vehicle reaches the programmed top speed and holds the vehicle at that speed.
Motor braking is automatically disengaged when vehicle speed slows below the programmed top
speed.
• Pedal Up Motor Braking (adjustable): Speed settings are programmable for IQ Plus vehicles. Motor
braking is activated when the accelerator pedal is released at or above the programmed speed. When
the vehicle slows to the programmed lower speed, motor braking will disengage. If no speed settings
are programmed, motor braking will be activated at any time accelerator is released, and it will only dis-
engage when the vehicle comes to a stop. Contact your Club Car dealer/distributor to inquire about this
programmable feature.
• Regenerative Braking: When motor braking is activated, the vehicle motor acts as a generator, slow-
ing the vehicle as it creates energy that is used to charge the batteries.
