Engine oilThe amount of oil your engine needs will de

pend on a number of factors, including driving
style. Increased oil consumption can occur
when
•the vehicle is new
• the vehicle is driven at higher engine
speeds frequently
Engine oil consumption checks should only be
made after the vehicle break
in period.!
Do not use any special lubricant additives,
as these may increase wear and damage the
drive assemblies. Using special additives not
approved by smart may cause damage not
covered by the smart Limited Warranty.
More information on this subject is available
at any smart center.

Warning!
In order to avoid potentially serious
burns:
• Use extreme caution when opening the
service flap if there are any signs of
steam or coolant leaking from the
cooling system, or if the coolant
temperature warning lampD in the
instrument cluster indicates that the
coolant is overheated.
• Do not remove pressure cap on coolant
reservoir if coolant temperature is
above 158°F (70°C). Allow engine to
cool down before removing cap. The
coolant reservoir contains hot fluid
and is under pressure.

Winter driving
208
>> Operation Before the onset of winter, have your vehicle
winterized at an authorized smart center. This
service includes:
>Check of anticorrosion and antifreeze
concentration.
• Addition of washer concentrate to the water
of the windshield/rear window.
Use a windshield washer concentrate la

beled for winter which is formulated for
temperatures below freezing point
(
page 308).
• Battery test. Battery capacity drops with
decreasing ambient temperature. A well
charged battery helps to make sure that the
engine can be started, even at low ambient
temperatures.
• Tire change.
Winter tiresAlways use winter tires at temperatures
below 45°F (7°C) and whenever wintry road
conditions prevail. Not all M+S rated tires
provide special winter performance. Make
sure the tires you use show the mountain/
snowflake marking.on the tire sidewall.
These tires meet specific snow traction
performance requirements of the Rubber
Manufacturers Association (RMA) and the
Rubber Association of Canada (RAC) and have
been designed specifically for use in snow
conditions. Use of winter tires is the only way
to achieve the maximum effectiveness of the
ABS and ESP
® in winter operation.
For safe handling, make sure that all mounted
winter tires are of the same make and have the
same tread design.Always observe the speed rating of the winter
tires installed on your vehicle. If the maximum
speed for which your tires are rated is below
the speed rating of your vehicle, you must
place a notice to this effect where it will be
seen by the driver. Such notices are available
at your tire dealer or any authorized smart
center.
G
Warning!
Winter tires with a tread depth of less
than
1/6 in (4 mm) must be replaced. They
are no longer suitable for winter opera

tion.

211 Drinking and driving Pedals Power assistance
G
Warning!
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 greatly increased when you
drink or take drugs and drive.
G
Warning!
Make sure that absolutely no objects are
obstructing the pedals’ range of move

ment. Keep the driver’s footwell clear of
all obstacles. If there are any floormats
or carpets in the footwell, make sure that
the pedals still have sufficient clearance.
During sudden driving or braking maneu

vers, the objects could get caught be

tween or beneath the pedals and restrict
your ability to brake or accelerate. This
could lead to accidents and injury.
G
Warning!
Without the engine running, there is no
power assistance for the brake and the
steering* systems. In this case, it is im

portant to keep in mind that a consider

ably higher degree of effort is necessary
to brake and steer the vehicle.
