Index15

Prevent water from entering the vehicle inte-
rior or the engine compartment. If you must
drive through standing water, bear in mind
that:
Rthe water level should not exceed the lower
edge of the vehicle body in still water
Ryou should drive no faster than at walking
pace.
Winter driving
GWARNING
If you shift down on a slippery road surface
in an attempt to increase the engine's
braking effect, the drive wheels could lose
their grip. There is an increased danger of
skidding and accidents.
Do not shift down for additional engine
braking on a slippery road surface.
GDANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous
gases such as carbon monoxide (CO) may
enter the vehicle. This is the case, e.g. if
the vehicle becomes trapped in snow. There
is a risk of fatal injury.
If you have to leave the engine running,
keep the exhaust pipe and the area around
the vehicle free of snow. To ensure an ade- quate supply of fresh air, open a window on
the side of the vehicle that is not facing
into the wind.
Have your vehicle winterproofed at a quali-
fied specialist workshop at the onset of win-
ter.
Drive particularly carefully on slippery road
surfaces. Avoid sudden acceleration, steer-
ing and braking maneuvers. Do not use cruise
control.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
XTry to bring the vehicle under control
using corrective steering.
XVehicles with automatic transmission:
shift the transmission to position N.The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Changes in the outside temperature are dis-
played after a short delay.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
You should pay special attention to road con-
ditions when temperatures are around freez-
ing point.
For more information on driving with snow
chains, see (
Ypage 179).
For more information on driving with summer
tires, see (
Ypage 179).
Observe the notes in the "Winter operation"
section (
Ypage 179).
Driving systems
Cruise control
General notes
Cruise control maintains a constant road
speed for you. Cruise control does not brake
the vehicle automatically. Only the engine's
braking effect is available. In order to
reduce speed and maintain distance to other
road users, you need to brake yourself. This
interrupts cruise control.
Use cruise control only if road and traffic
conditions make it appropriate to maintain a steady speed for a prolonged period. You can
use cruise control at speeds above 20 mph
(30 km/h).
Important safety notes
If you fail to adapt your driving style, cruise
control can neither reduce the risk of an
accident nor override the laws of physics.
Cruise control cannot take into account road,
weather or traffic conditions. Cruise control
is only an aid. You are responsible for the
distance to the vehicle in front, for vehicle
speed, for braking in good time and for stay-ing in lane.

!For cleaning your vehicle, do not use any
of the following:
Rdry, rough or hard cloths
Rabrasive cleaning agents
Rsolvents
Rcleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective
films with hard objects, e.g. a ring or ice
scraper. You could otherwise scratch or
damage the surfaces and protective film.
!Do not park the vehicle for an extended
period straight after cleaning it, partic-
ularly after having cleaned the wheels with
wheel cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked.
Regular care of your vehicle is a condition
for retaining the quality in the long term.
Use care products and cleaning agents rec-
ommended and approved by smart.
Exterior care
Automatic car wash
GWARNING
Braking efficiency is reduced after wash-
ing the vehicle. There is a risk of an acci-
dent.
After the vehicle has been washed, brake
carefully while paying attention to the
traffic conditions until full braking power
is restored.
!Never clean your vehicle in a Touchless
Automatic Car Wash as these use special
cleaning agents. These cleaning agents can
damage the paintwork or plastic parts.
!Make sure that:
Rthe side windows are fully closed
Rthe climate control blower is switched
off
Rthe windshield wiper switch is at posi-
tion 0
The vehicle may otherwise be damaged.
You can wash the vehicle in an automatic car
wash from the very start.
If the vehicle is very dirty, pre-wash it
before cleaning it in an automatic car wash.
After using an automatic car wash, wipe off
wax from the windshield and the wiper blades.
This will prevent smears and reduce wiping
noises caused by residue on the windshield.
Washing by hand
In some countries, washing by hand is only
allowed at specially equipped washing bays.
Observe the legal requirements in each coun-
try.
XDo not use hot water and do not wash the
vehicle in direct sunlight.
XUse a soft sponge to clean.
XUse a mild cleaning agent, such as a car
shampoo approved by smart.
XThoroughly hose down the vehicle with a
gentle jet of water.
XDo not point the water jet directly towards
the air inlet.
XUse plenty of water and rinse out the sponge frequently.
XRinse the vehicle with clean water and dry
thoroughly with a chamois.
XDo not let the cleaning agent dry on the
paintwork.
Carefully remove all deposits of road salt as
soon as possible when driving in winter.
Power washers
GWARNING
The water jet from a circular jet nozzle
(dirt blasters) can cause invisible exte-
rior damage to the tires or chassis compo- nents. Components damaged in this way may
fail unexpectedly. There is a risk of an
accident.
Care155
>> Maintenance and care.
Z

RAfter fitting new tires, run them in at mod-
erate speeds for the first 60 miles (100 km),
as they only reach their full performance
after this distance.
RDo not drive with tires which have too little
tread depth, as this significantly reduces
the traction on wet roads (hydroplaning).
RReplace the tires after six years at the lat-
est, regardless of wear.
Winter operation
General notes
Have your vehicle winterproofed at a quali-
fied specialist workshop at the onset of win-
ter.
Observe the notes in the "Changing a wheel"
section (
Ypage 196).
Driving with summer tires
At temperatures below 45 ‡(+7 †), summer
tires lose elasticity and therefore traction
and braking power. Change the tires on your
vehicle to M+S tires. Using summer tires at
very cold temperatures could cause tears to
form, thereby damaging the tires perma-
nently. smart cannot accept responsibility
for this type of damage.
GWARNING
Damaged tires can cause tire inflation
pressure loss. As a result, you could lose
control of your vehicle. There is a risk of
accident.
Check the tires regularly for signs of dam- age and replace any damaged tires imme-
diately.
M+S tires
GWARNING
M+S tires with a tire tread depth of less
than 00CFin (4 mm) are not suitable for use in
winter and do not provide sufficient trac-
tion. There is a risk of an accident.
M+S tires with a tread depth of less than 00CF
in (4 mm) must be replaced immediately.
At temperatures below 45 ‡(+7 †) use winter
tires marked with M+S.
Only winter tires bearing the 004Dsnowflake
symbol in addition to the M+S marking pro-
vide the best possible grip in wintry road
conditions. Only these tires will allow driv-
ing safety systems such as ABS and ESP
®to
function optimally in winter. These tires
have been developed specifically for driving
in snow.
Use M+S tires of the same make and tread on
all wheels to maintain safe handling charac- teristics.
Always observe the maximum permissible
speed specified for the M+S tires you have
mounted. Therefore, only use tire types and
sizes approved for smart. Observe the tire
load rating and speed rating required for
smart.
Tires with a specified direction of rotation
have additional benefits, e.g. if there is a
risk of aquaplaning. These advantages can
only be gained if the tires are fitted corre-
sponding to the direction of rotation.
An arrow on the sidewall of the tire indicates
its correct direction of rotation.
When you have mounted the M+S tires:
XCheck the tire pressures (Ypage 180).
XVehicles for USA: restart the tire pressure
monitor (Ypage 185).
Snow chains
GWARNING
If snow chains are installed to the front
wheels, they may drag against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tires.
There is a risk of an accident.
To avoid hazardous situations:
Rnever install snow chains to the front
wheels
Ralways install snow chains in pairs to the rear wheels.
Winter operation179
>> Wheels and tires.
Z

All passenger car tires must conform to the
statutory safety requirements in addition to
these grades.
iThe actual values for tires are vehicle-
specific and may deviate from the values in
the illustration.
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested under controlled conditions on a specified
U.S. government course. For example, a tire
graded 150 would wear one and one-half times
as well on the government test track as a tire
graded 100.
The relative performance of tires depends
upon the actual conditions of their use, how- ever, and may depart significantly from the
norm due to variations in driving habits,
service practices and differences in road
characteristics and climate conditions.
Traction
GWARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
!Avoid wheelspin. This can lead to damage
to the drive train.
The traction grades – from highest to lowest –
are AA, A, B and C. Those grades represent the
tire's ability to stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of
asphalt and concrete. A tire marked C may
have poor traction performance.
The safe speed on a wet, snow covered or icy
road is always lower than on dry road surfa-
ces.
You should pay special attention to road con-
ditions when temperatures are around freez-
ing point.
smart recommends a minimum tread depth of
00CF in (4 mm) on all four winter tires. Observe
the legally required minimum tire tread
depth (
Ypage 178). Winter tires can reduce
the braking distance on snow-covered surfa- ces in comparison with summer tires. The
braking distance is still much further than on
surfaces that are not icy or covered with snow.
Take appropriate care when driving.
Further information on winter tires (M+S
tires) (
Ypage 179).
Temperature
GWARNING
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, underinflation, or excessive load-
ing, either separately or in combination,
can cause excessive heat build-up and pos- sible tire failure.
The temperature grades are A (the highest), B
and C. They represent the tire's resistance to
the generation of heat and its ability to dis-
sipate heat when tested under controlled con-
ditions on a specified indoor laboratory test
wheel. Sustained high temperature can cause
the material of the tire to degenerate and
reduce tire life, and excessive temperature
can lead to sudden tire failure. The grade C
corresponds to a level of performance which
all passenger car tires must meet under the
Federal Motor Vehicle Safety Standard No.
109. Grades B and A represent higher levels of
performance on the laboratory test wheel than
the minimum required by law.
190All about wheels and tires
>> Wheels and tires.

Optionally, tires with a maximum speed of
over 149 mph (240 km/h) may have "ZR" in the
size description, depending on the manufac-
turer (e.g. 245/40 ZR 18).
Rim diameter:rim diameter0085is the diam-
eter of the bead seat, not the diameter of the
rim flange. The rim diameter is specified in
inches (in).
Load-bearing index: load-bearing index0083
is a numerical code that specifies the maxi-
mum load-bearing capacity of a tire.
Do not overload the tires by exceeding the
specified load limit. The maximum permis-
sible load can be found on the vehicle's Tire
and Loading Information placard on the
B-pillar on the driver's side (
Ypage 185).
Example:
Load-bearing index 91 indicates a maximum
load of 1,356 lb (615 kg) that the tires can bear.
For further information on the maximum tire
load in kilograms and lbs, see (
Ypage 193).
For further information on the load bearing
index, see "Load index" (
Ypage 193).
Speed rating: speed rating0084specifies the
approved maximum speed of the tire.
iTire data is vehicle-specific and may
deviate from the data in the example.
Regardless of the speed rating, always
observe the speed limits. Drive carefully and
adapt your driving style to the traffic con-
ditions.

ROptionally, tires with a maximum speed of
over 149 mph (240 km/h) may have "ZR" in the size description, depending on the manu-
facturer (e.g. 245/40 ZR18).
The service specification is made up of
load-bearing index 0083and speed rating
0084.
RIf the size description of your tire
includes "ZR" and there are no service
specifications, ask the tire manufacturer
in order to find out the maximum speed.
If a service specification is available, the maximum speed is limited according to the
speed rating in the service specification.
Example: 245/40 ZR18 97 Y.In this example,
"97 Y" is the service specification. The
letter "Y" represents the speed rating. The
maximum speed of the tire is limited to
186 mph (300 km/h).
RThe size description for all tires with
maximum speeds of over 186 mph (300 km/h)
must include "ZR", andthe service speci-
fication must be given in parentheses.
Example: 275/40 ZR 18 (99 Y). Speed rating
"(Y)" indicates that the maximum speed of
the tire is over 186 mph (300 km/h). Ask the
tire manufacturer about the maximum
speed.
