- In adverse weather conditions such as fog,
heavy rain, b low ing snow or spraying water.
- On roads where oncoming traffic may be partially obscu red, such as expressways .
-If there are road users with poor lighting,
such as bicyclists .
- In tight c urves and on s teep hills.
- In poorly lit areas.
- With strong reflecto rs, such as s igns.

A WARNING ~
Cu rved mirror surfaces (for example convex)
enlarge the field of vision. However, they make objects in the mirror appear smaller
and farther away. Your may est imate incor­
rect ly when you use these mirrors to gauge
your distance from the veh icles beh ind you

of an accident .
(D Note
-Applies to vehicles with power folding exte­
rior mirrors : if the m irro r hous ing was
moved by outs ide forces (such as an impact
w hen maneuve ring), you must use the pow-
er folding function to fold the mirro r all the

hand because this would impair the func­
tion of the mirror mechanism.
- Applies to vehicles without power folding
exterior mirrors: if the mirror housing was
moved by outside forces (such as an impact
when maneuvering), you must move it back in place by hand.
- If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.
Never fold power folding exterior mirrors*
by hand. Only fold them in and out using
the power controls.
(D) Tips
If the power adjustment fails, both mirrors
can be adjusted by hand by pressing on the
edge of the mirror surface.
Dimming the mirrors
Your vehicle is equipped with a manual or auto ­
matic* dimming rearview mirror .
Manual dimming rearview mirror
• Pull the lever on the bottom of the mirror back .
Automatic dimming mirrors*
• The interior and exterior mirrors dim automati­
cally when light shines on them, for example
from headlights on a vehicle behind you.
& WARNING
Applies to: vehicles with automatic dimming rearview
mirror
Electrolyte fluid can leak out from broken
mirror glass. This liquid can irritate the skin,
eyes and respiratory system. If there is con­
tact with the fluid, flush immediately with
plenty of water . Consult a physician if neces­
sary.
- Repeated or long-term exposure to electro­
lyte fluid can lead to irritation of the air­
ways, especially in people with asthma or
other respiratory conditions. Take deep
breaths immediately after leaving the vehi­
cle or, if this is not possible, open all of the
doors and windows as wide as possible.
56
-
- If electrolyte fluid enters the eyes, flush
them thoroughly with a large amount of clean water for at least 15 minutes and then
seek medical attention.
- If electrolyte fluid comes into contact with
the skin, flush the affected area with clean
water for at least 15 minutes and then clean
with soap and water and seek medical at­
tention. Clean affected clothing and shoes
thoroughly before wearing again.
- If the fluid was swallowed and the person is
conscious, flush the mouth with water for at
least 15 minutes. Do not induce vomiting
unless this is recommended by medical pro­
fessionals. Seek medical attention immedi­
ately.

Electrolyte fluid can leak out from broken
mirror glass. This liquid damages plastic sur­
faces. Clean this liquid as quickly as possible
with a wet sponge.
(D Tips
Applies to: vehicles with automatic dimming rearview

- If there is frost, make sure the windshie ld
wiper blades are not frozen to the wind­
sh ield. Switching on the windshield wipers
when the blades are frozen to the wind­

_& WARNING
For safety reasons, the windshield wiper
blades should be replaced once or twice each
year .
(D Note
-The windshield wiper blades must only be
folded away when in the service position!
Otherwise, you risk damaging the paint on
the hood or the windshield wiper motor .
- You should not drive your vehicle or press
the windshield wiper lever when the wiper
arms are folded away from the windshield.
The windshield wipers would move back in­
to their original position and could damage
the hood and windshield .
@ Tips
- You can also use the service position, for ex­
ample, if you want to protect the windshield
from icing by using a cover.
- You cannot activate the service position
when the hood is open .

next traffic light is red. This produces an engine
braking effect, which helps to protect the brakes
and tires and reduces the emissions and fuel con­
sumption to zero (fuel shut-off during decelera­
tion).
Shift efficiently
An effective way to save fuel is to upshift earlier.
Staying in a gear too long uses fuel unnecessari­
ly .
Press down on the accelerator pedal slowly and
avoid "kick-down".
Avoid full acceleration
You should rarely travel at the maximum vehicle
speed. High speeds cause a disproportionately
high increase in fuel consumption, emissions and
traffic noise. Slower driving saves fuel.
Reduce idling time
The Start/Stop system* helps to reduce the idling
time automatically. In vehicles without the Start/
Stop system, it is efficient to switch the engine
off when stopped
at railroad crossings and long
red lights. Depending on the version of the en­
gine, stopping the engine for as little as five sec­
onds once it has reached operating temperature
still saves more fuel than leaving the engine run­ ning
-even when taking into account the amount
of extra fuel that is used to restart the engine.
It takes a very long time in idle to warm the en­
gine up to operating temperature. Wear and
emissions are especially high in the warm-up
phase. Therefore, you should begin driving im­
mediately after starting the engine. Avoid high
RPMs while doing this.
Have maintenance performed regularly
By having maintenance performed regularly on
your vehicle, you can help to reduce fuel con­
sumption before you even start to drive. The maintenance condition of your vehicle not only
affects traffic safety and long-term value but al­
so impacts
fuel consumption. A poorly main­
tained engine can lead to fuel consumption that
is 10% higher than normal.
Driving
Avoid short trips
The engine and emissions control system must
reach their optimal
operating temperature to ef­
fectively reduce consumption and emissions.
A cold engine uses a disproportionately high
amount of fuel. The engine reaches operating
temperature and consumption normalizes only
after approximately 2.5 miles (4 km).
Check the tire pressure
To save fuel, make sure the tires are always in­
flated to the correct pressure
r=;, page 33 5. The
fuel consumption can increase by S% if the pres­
sure is only 0.5 bar too low. Due to the increased
rolling resistance, low tire pressures will also
lead to greater tire
wear and will affect driving
behavior.
Do not drive on
winter tires year-round, as this
will consume up to 10% more fuel.
Eliminate unnecessary weight
Since every kilogram of extra weight increases
fuel consumption, a quick inspection of the lug­
gage compartment may be worth it to avoid un­
necessary weight.
When not being used, a roof rack should be re­
moved to decrease the wind resistance of the ve­
hicle. You will save approximately 12% of your
fuel when at speeds from 62-75 mph
(100-120 km/h).
Save energy
The engine drives the generator, which generates
electricity; the fuel consumption also increases
with the demand for electricity. Therefore, switch
electrical equipment off when you no longer
need it. Examples of equipment that uses a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating*.
(D Note
- Do not leave engine idling unattended after
starting. If warning lights should come on
to indicate improper operation, they would go unheeded. Extended idling also produces
heat, which could result in overheating or

A WARNING
To reduce the risk of poisoning, never allow
the engine to run in confined spaces.
@ Note
Avoid high engine speed, full throttle, and
heavy engine load if the engine has not
reached operating temperature yet. You could
damage the engine.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately. This
re­
duces unnecessary emissions.
(D Tips
-Some noise after starting the engine is nor­
mal and is no cause for concern.
- If you leave your vehicle with the ignition
switched on, the ignition will switch off

A WARNING
-- Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steer ing is not guaranteed. You must use
mo re force to turn or brake. Because you
cannot steer and brake as you usually
wou ld, this could lead to accidents and seri­
ous injuries.
-Always take the key with you whenever yo u
leave your vehicle. Otherwise, the engine

could roll unintentionally .
