_& WARNING
= -
- Never rely exclusively on the outside
temperature display to determine if a
road surface is icy or not. Keep in mind
that road surfaces, especially bridges
and overpasses, could be ice covered and
slippery even at an outside temperature
above 41 °F
(+5 °().
-Always remember, even if the "snow­
flake" symbol (ice warning) does not ap­
pear in the d isplay, black ice could be on
the road.
- Always reduce your speed and drive with special care in cold weather cond itions
when the chance of encountering icy
road surfaces increases.
(D Tips
-If the vehicle is stationary, or if you are
dr iving at a very low speed, the tempera­
ture shown in the d isplay m ight be
slightly higher than the actual outside
temperature . Thi s is caused by the heat
being radiated from the engine.
- Yo u can select the units used for temper­
ature, speed and other measurements in
the MMI.

You can ca ll u p t he following information in
the on-board computer:
- Date
- Dr iving t ime (h) from the sho rt-term memo-
ry
- Average consumption in MPG ( l/100 km)
from the short-term memory
- Average speed i n mph (km/h) from the

soon as the switch(®) is released, or the accel ­
erator pedal is depressed, emergency braking
stops.
.&_ WARNING
Emergency braking should only be used in
an emergency, when the normal foot brake
has failed or the brake pedal is obstructed .
Using the parking brake to perform emer­
gency braking will slow your vehicle down
as if you had made a full brake applicat ion.
The laws of physics cannot be suspended
even with ESC and its associated compo­
nents (ABS, ASR, EDL). In corners and
when road or weather conditions are bad
'
a full brake application can cause the vehi-
cle to skid or the rear end to break away -
r isking an accident.
Start-Stop-System
Description
Appl ies to vehicles : wit h Start-Stop-System
The Start-Stop-System can help increase fuel
economy and reduce CO
2 emissions.
I n the Start-Stop-mode, the engine shuts off
automatically when the vehicle is stopped,
such as at a traffic light. The ignit io n remains
sw itched on dur ing th is stop phase. The en­
gine will be automatically restarted when
needed.
The last Start-Stop-System setting (on/off us­
ing the button
l ignition is turned on . The LED in the
l --1 but­
ton turns on when the Start-Stop-System is
switched off manually.
Basic requirements for the Start-Stop
mode
- The driver's door is closed .
- The driver' seat belt is latched.
- The hood is closed.
- T he veh icle must have been driven faster
~ than 2.5 mph (4 km/h) since the last stop.

.&_ WARNING
-Never let the vehicle roll with the engine
sw itched off . You could lose control over
the vehicle. This can lead to a collision
and serious injuries.
- The brake booster and the steering sup­
port do not work while the engine is
sw itched off. More force is required to
stop and to steer the vehicle.
- To reduce the risk of injuries, make sure
that the Start-Stop-System is turned off
when working in the eng ine compart­
ment ¢

A WARNING
To help prevent poisonous exhaust gas
from being drawn into the vehicle, always keep the rear lid closed while driving .
- Never transport objects larger than
those fitting completely into the luggage
area because the rear lid cannot be fully
closed.
- If you absolutely must drive with the rear
lid open, observe the following notes to
reduce the risk of poisoning:
- Close all windows,
- Close the power roof*,
- Open all air outlets in the instrument
panel,
- Switch off the air recirculation,
- Set the fresh air fan to the highest
speed.
A WARNING
Always make sure that the doors, all win­ dows, the power roof* and the rear lid are
securely closed and locked to reduce the
risk of injury when the vehicle is not being
used.
- After closing the rear lid, always make
sure that it is properly closed and locked.
- Never leave your vehicle unattended es­
pecially with the rear lid left open. A
child could crawl into the vehicle through
the luggage compartment and close the
rear lid becoming trapped and unable to
get out. Being trapped in a vehicle can
lead to serious personal injury.
- Never let children play in or around the
vehicle .
- Never let passengers ride in the luggage
compartment. Vehicle occupants must
always be properly restrained in one of
the vehicle's seating positions.
Gj) Tips
-Air circulation helps to reduce window
fogging. Stale air escapes to the outside
through vents in the trim panel. Be sure
to keep these slots free and open .
-
Driving Safely 133
-The tire pressure must correspond to the
load. The tire pressure is shown on the
tire pressure label. The tire pressure la­
bel is located on the driver's side B-pillar.
The tire pressure label lists the recom­
mended cold tire inflation pressures for
the vehicle at its maximum capacity
weight and the tires that were on your
vehicle at the time it was manufactured.
For recommended tire pressures for nor­
mal load conditions, please see chapter
~page 244.
Tie-downs
The luggage compartment is equipped with
four tie-downs to secure luggage and other
items.
Use the tie-downs to secure your cargo prop­
erly~
page 132, Loading the luggage com­
partment.
In a collision, the laws of physics mean that
even smaller items that are loose in the vehi­
cle will become heavy missiles that can cause
serious injury. Items in the vehicle possess en­
ergy which vary with vehicle speed and the
weight of the item. Vehicle speed is the most
significant factor.
For example , in a frontal collision at a speed
of 30 mph (48 km/h), the forces acting on a
10-lb (4.5 kg) object are about 20 times the
normal weight of the item. This means that
the weight of the item would suddenly be about 200 lbs. (90 kg) . You can imagine the
injuries that a 200 lbs . (90 kg) item flying
freely through the passenger compartment
could cause in a collision like this.
A WARNING
Weak, damaged or improper straps used
to secure items to tie-downs can fail dur­
ing hard braking or in a collision and cause
serious personal injury.
-Always use suitable mounting straps and properly secure items to the tie-downs in
.
