CERAD theory test - In-car technology || Answered Accurately.
When should 'park' be selected? correct answers When the vehicle is parked, before the engine is
turned off
You should never move the gear lever to the ___ position whilst the vehicle is in motion correct
answers P
What is often required when selecting 'reverse'? correct answers Footbrake is depressed
What should you be aware of when selecting 'reverse'? correct answers The vehicle may begin to
roll backward if you don't have a foot on the brake
What happens when the gear/lever is in neutral? correct answers No power is transmitted from
the engine to the drive wheels when in neutral
Neutral should or should not be selected when making temporary stops in traffic? correct
answers Should not
When 'drive' is selected on an automatic, what will it allow the transmission to do? correct
answers Make automatic adjustments to speed, engine loading and accelerator position
Automatics should always be left in which gear when not being driven? correct answers P (park)
What special programmes do emergency vehicles tend to have? correct answers - Lock-down (or
shift restrictions)
- Sport
- Manual selection
What is lock-down (or shift restrictions? correct answers An effective means of controlling an
automatic gearbox while descending steep gradients, overtaking or negotiating a corner or
roundabout to ensure vehicle stability
What does the number of lockdown options (or restrictions) depend on? correct answers How
many gears the vehicle has
The number of lock down options will always be less than the number of __________ present
correct answers Gears
What is lock down 1 and when/why is it used? correct answers The vehicle is locked in first gear
and will not change up to any other gear.
Used for very steep downhill gradients, to utilise engine compression to help control sped and
lessen the load on the brakes
, What is lock down 2 and when/why is it used? correct answers Same as lock down 1 but there is
less engine compression. It will not change up to 3rd or any higher gear.
Used to control speed on descents in the same way as lock down 1. This option is suitable for
fairly steep downhill gradients or negotiating corners.
What are other lock down positions and when/why are they used? correct answers The maximum
upshift will be represented by the lockdown position selected (e.g., If lockdown position 4 has
been selected, then the vehicle will utilise all gears up to and including the 4th gear, but will not
go into 5th or 6th.
May be used to control the vehicle like a manual clutchless vehicle.
You might choose to lock down a lower gear in a built-up area, where there are a number of
hazards to improve control through the accelerator.
Driving the vehicle for a prolonged period of time in a lock down option can cause.... correct
answers The automatic transmission fluid to overheat, damage ton the transmission system
What happens in sport mode? correct answers The gearbox holds lower gears for longer,
allowing for brisker acceleration as the gearbox may not need to change down a gear in order to
accelerate at maximum power
What might sport mode disengage/change? correct answers Electronic stability program (ESP),
antilock brake system (ABS), or start-stop technology
In manual selection, when is it best to move the selector lever/paddles? correct answers Under
light acceleration
Most modern systems will override your lever/gear selection if... correct answers The engine
revs or speed are too high
With both automatic and manual gearboxes, you must be travelling at the correct speed for the
gear you want to select manually. _________________ ______________ should be avoided
correct answers Secondary braking
What is 'creep'? correct answers If any selector position other than 'P' or 'N' is selected, and the
footbrake or handbrake is not applied then the vehicle will tend to creep forward/backward at
low speed even when pressure is not applied to the accelerator
The rate of creep varies in response to.... correct answers Gravity
How can you control 'creep'? correct answers Use the footbrake
When is 'creep' particularly useful? correct answers When manoeuvring at low speeds or in slow
moving traffic
When should 'park' be selected? correct answers When the vehicle is parked, before the engine is
turned off
You should never move the gear lever to the ___ position whilst the vehicle is in motion correct
