TECHNOLOGY QUESTIONS WITH
CORRECT ANSWERS
Acceleration Skid Control(ASC)/Anti-Slip Regulator (ASR) must not
be deactivated during normal use - true or false? ...ANS: True
Automatics should always be left in which gear when not being
driven? ...ANS: P (park)
Do not engage 'D' or 'R' with a high revving engine - true or
false? ...ANS: True
Driving the vehicle for a prolonged period of time in a lock down
option can cause.... ...ANS: The automatic transmission fluid to
overheat, damage ton the transmission system
Gentle bends can normally be negotiated in 'D' but for a series of
bends, you should manually select a suitable gear before the first
bend - true or false? ...ANS: True
How are retarders activated? ...ANS: Normally automatically
when the driver depresses the brake pedal
How can we overcome the risk of automatic vehicles changing into a
higher gear when descending down a hill? ...ANS: Manually
locking or changing down to a low ratio gear - this will provide
compression braking to enhance the vehicle braking
,ASCORERS STUVIA
How can we prevent the sensation of 'losing control' caused by
gravity on steep downhill slopes? ...ANS: Timely and judicious use
of lock-down or a manual selection
How can you activate the siren? ...ANS: Press the button on the
control panel, and you can then switch it on/change the sound/tone
by pressing the horn or foot switch.
How can you control 'creep'? ...ANS: Use the footbrake
How can you turn off the siren? ...ANS: Press the horn or foot
switch twice, or press the button on the control panel
How do lane departure warnings alert you? ...ANS: Buzzer or
vibration
How do lane departure warnings work? ...ANS: Uses a camera or
infrared sensor to watch road markings and detect if the vehicle
strays away from the lane it is traveling in
How do retarders work? ...ANS: When the footbrake is applied,
this operates the circuits in the control box which close and energise
the retarder - this applies friction-free braking torque to the rear
wheels, slowing the vehicle down.
How do you know if the Electronic Stability Control (ESC) system is
active? ...ANS: A warning light may flash
How do you know when Acceleration Skid Control(ASC)/Anti-Slip
Regulator (ASR) is active? ...ANS: A warning light in the
instrument cluster flashes
How does 'kick down' work? ...ANS: Apply the accelerator pedal
downwards rapidly to the furthest limit of its travel. After a very
, ASCORERS STUVIA
brief interval, the transmission will change down to the next lowest
gear and rapid acceleration will ensure. Holding the pedal down
may result in a further subsequent gear change down and yet more
acceleration. Relaxing pressure on the accelerator results in loss of
acceleration and a change back up to a higher gear.
How does Acceleration Skid Control (ASC)/Anti-slip Regulator
(ASR) work? ...ANS: Transfers the power from the tyres to the
road surface for a set period, which improves the stability of the
vehicle. It works by applying brake effect to individual drive wheels
and reduces engine torque to prevent the wheels from spinning.
How does Electronic Brake Force Distribution (EBD) work? ...ANS:
Detects which wheel has more or less grip and will vary the braking
force to the wheels to reduce the chance of skidding
How does Emergency Brake Assist (EBA) work? ...ANS: The
system interprets braking behaviour by assessing the rate at which
the brake pedal is active, and initiates full braking.
How does the Electronic Stability Control (ESC) work? ...ANS:
Recovers vehicle stability by braking individual wheels and reducing
power output from the engine
How does the emergency start button work? ...ANS: Power is
sourced from an auxiliary battery that should be sufficient to start
the vehicle
How does the hill hold assist function work? ...ANS: The device
holds the hydraulic pressure on the brakes, keeping the brake pads
pressed against the brake discs even when the foot is removed from
the brake pedal, until the clutch has reached the friction point. It
then releases them, allowing for a hill start to be performed without
