The smart fortwo comes standard with many active safety features
that will introduce you to a whole new set of acronyms and keep you safer in the process.
esp® -- One of the standard features on your smart fortwo is something called Electronic
Stability Program or esp®. When the esp® sensors indicate a skid or swerving of your car,
they automatically control the engine throttle and the Anti-Lock brakes to maintain your
present course. Also integral to the esp® safety system is Electronic Brake-Force
Distribution Control (EBD), which helps to prevent the rear wheels from over-braking.
ABS - Another feature of esp® is the Anti-Lock Brake Systems (ABS).
With ABS, you can hit your brakes hard knowing the ABS circuitry will apply and
release each brake independently to keep you from skidding regardless of the type
of road surface each wheel is on.
CBC - When you enter a corner and apply your brakes, the unequal forces at each
wheel can result in a skid or a complete "end-around". With Cornering Brake Control
(CBC) the inner wheels require less brake force due to less traction. CBC counteracts
a potential tendency to swerve by distributing brake forces selectively - even below
the threshold of ABS activity.
BAS - Avoiding accidents is often measured in inches.
Electronic Brake Assist can sense when you have stepped on the brake
quickly but have not applied it hard enough to activate the ABS system.
It can be the difference in reaction time you need to avoid an accident.
ASC and ETC - Acceleration Skid Control (ASC) and Engine
Torque Control (ETC) are designed to help the smart fortwo
move forward on slippery surfaces. ASC acts much like a differential
lock but does it by directing power to the wheel offering
optimum traction. ETC provides engine control when driving
on slippery surfaces. It "feathers" the throttle on low traction
acceleration and limits torque in down shifting applications.
HSA - The 5-speed automated manual transmission of the smart fortwo is equipped with Hill
Start Assist (HSA) which allows you to pull away on a hill without having to apply
the handbrake. As you lift your foot from the brake pedal while sitting stopped on a
hill, HSA holds the brakes on for about a second to give you time to move your foot to
the accelerator. So don't worry about driving your smart fortwo in San Francisco.
