Driving instructions
Drinking and driving
GWarning!
Do not drink alcohol or take drugs and drive
or allow anyone to drive who has been
drinking alcohol or taking drugs. Even a
small amount of alcohol or drugs can affect
your reflexes, perceptions and judgment.
The possibility of a serious or even fatal
accident are greatly increased when you
drink or take drugs and drive.
Pedals
GWarning!
Make sure absolutely no objects are
obstructing the pedals’ range of motion.
Keep the driver’s footwell clear of all
obstacles. If there are any floormats* or
carpets in the footwell, make sure the
pedals still have sufficient clearance.
During sudden acceleration or braking
maneuvers, the objects could get caught
between or beneath the pedals and restrict
your ability to brake or accelerate. This
could lead to accidents and/or injury.
Power assistance
GWarning!
With the engine not running, there is no
power assistance for the brake and
steering* systems. In this case, it is
important to keep in mind that a
considerably higher degree of effort is
necessary to brake and steer the vehicle.
Adapt your driving accordingly.
BrakesGWarning!
Make sure not to endanger any other road
users when carrying out braking
maneuvers.
Refer to the description of the hydraulic
brake assistant ( Y page 46).
! Because the ESP ®
operates
automatically, the engine must be turned
off (ignition switched off) when the
parking brake is being tested on a brake
test dynamometer. Active braking action
through the ESP ®
may otherwise seriously
damage the brake system which is not
covered by the smart Limited Warranty.
Brake pad wear or a leak in the brake system
may be the reason for low brake fluid level
in the brake fluid reservoir.
The brake fluid level in the brake fluid
reservoir may be too low if the brake
warning lamp in the instrument cluster
comes on ( Y page 22) although the parking
brake is released.
Have the brake system inspected
immediately. Contact an authorized smart
center.
All checks and service work on the brake
system should be carried out by qualified
technicians only. Contact an authorized
smart center.
Only install brake pads and use brake fluid
recommended by smart.
Inclines
! When driving down long and steep
grades, relieve the load on the brakes by
shifting into a lower gear to use the
engine’s braking power. This helps
prevent overheating of the brakes and
reduces brake pad wear.
When using the engine’s braking power, a
drive wheel may not spin for an extended
period of time, e.g. on slippery road

GWarning!
When the ABS system is malfunctioning, the wheels may lock during hard braking, reducing
steering capability and extending the braking distance.
When the ABS is switched off due to a malfunction, the ESP ®
is also switched off. The basic
driving and braking functions are still available.
The risk of your vehicle skidding is then increased in certain situations. You should
therefore always adapt your speed and driving style to the prevailing road and weather
conditions.

Driving with the brake warning lamp illuminated can result in an accident. Have your brake
system checked immediately if the brake warning lamp stays on.
Do not add brake fluid before checking the brake system.
! If you find that the brake fluid in the brake fluid reservoir has fallen to the minimum
mark or below, have the brake system checked for brake pad thickness and leaks
immediately. Contact an authorized smart center immediately. Do not add brake fluid
as this will not solve the problem.

to children.XHave the system checked at an authorized smart center.GWarning!
If the SRS indicator lamp does not come on when you switch on the ignition or does not go
out again after a few seconds once the engine is running or comes on again, the supplemental
restraint systems are malfunctioning.
In the event that a malfunction of the SRS is indicated as described in scenario 2, the SRS
may not be operational. For your safety, we strongly recommend that you contact an
authorized smart center immediately to have the system checked; A malfunctioning SRS
system may not deploy when needed in an accident resulting in serious or fatal injury, or
it might deploy unexpectedly and unnecessarily which could result in an accident and/or
injury to you or to others.
! If the SRS indicator lamp comes on while driving, have the system checked at an
authorized smart center immediately.
It is possible that the air bag and the emergency tensioning device could be activated
unintentionally or will not function in the event of an accident.
i Information on the operating principle of the air bags can be found in the “Safety”
section ( Y page 33).

Driving when your engine is overheated can cause some fluids which may have leaked into
the engine compartment to catch fire. You could be seriously burned.
Steam from an overheated engine can cause serious burns which can occur just by opening
the engine hood. Stay away from the engine if you see or hear steam coming from it.
Stop the vehicle in a safe location away from other traffic. Turn off the engine, get out of
the vehicle and do not stand near the vehicle until the engine has cooled down.
! Among other possible causes, the poly-V-belt could be broken. Do not continue to
drive. Otherwise, the engine will overheat due to an inoperative water pump which may
result in damage to the engine.
