Economical and environmentally-friendly
driving
The amount of fue l cons umption, t he e nvir on­
men tal impac t an d the wea r to the engine,
b rak es and t ires depen ds mos tly on yo ur dr iv ing
s tyle. W it h an anticipatory and econom ic dr iv ing
s tyle, f uel consum ption can be re du ced by ap­
p roximate ly 1 0-15% . The followi ng tips will help
you conse rve the environment and you r money at
the same time .
Anticipatory driving
A vehicle uses the mos t fu el when a ccele ra tin g.
W hen yo u dr ive wi th a ntici pat ion, you do not
need to brake as ofte n an d so yo u acceler ate less .
W hen possi ble, let your vehi cle coast w it h a
gear
engaged ,
for example when you notice that the
next tra ffic light is red . This p roduces an engine
b raking effect, wh ich helps to protect the brakes
a n d tires a nd reduces t he emissions a nd f uel con­
sumpt io n to zero (fuel shut-off dur ing decelera­
tion) .
Shift efficiently
Upshift ing earlier is an effective way to save fue l.
Staying in a gear too long uses fue l unnecessari­
l y .
Press down on the acce le rato r peda l slowly and
avoid "k ic k-dow n".
Avoid full acceleration
You s hould rare ly tr ave l a t t he m axim um ve hicle
speed . High speeds cause a d isp roportionately
h ig h inc rease in fuel consumption, emissions an d
traffic no ise . Slower driving saves fuel.
Reduce idling time
T h e St art /S top system * he lps t o redu ce the i dlin g
time autom atically . In vehicles wi tho ut the Start /
Sto p system, it is eff ic ient to sw itch t he engine
off w hen stopped at ra ilroad cross ings a nd long
red lights . Depending on t he ve rsion of the en­
g ine, stopping the eng ine for as litt le as five sec­
onds once it has reached ope rat ing tempe rature
Driving
st ill saves mo re fue l th an leav ing t he en gine run ­
ning -even when taking into acco unt the amount
of ext ra fuel t hat is use d to restart t he e ngi ne.
It tak es a ve ry long time in idl e to warm the en ­
gine up to o peratin g tem perature . Wear an d
emissions are especially high in the warm -up
phase. The refore, you s hould begin drivi ng im ­
med iate ly after starting the eng ine. Avoid h igh
RPMs wh ile doing this.
Have maintenance performed regularly
By hav ing maintenance pe rformed reg ularly o n
yo ur vehicle, you can help to reduce fue l con ­
s u mption before you even sta rt to drive. The
maintenance cond ition of your vehicle not on ly
affects traffic safety and long-term va lue b ut al­
so impacts
fuel consumption . A poorly ma in­
ta ined engi ne ca n lead to fue l co nsump tion that
i s 1 0% hig her th an no rmal.
Avoid short trips
The eng ine and emissions contro l system must
r each their optima l
operating temperature to ef­
fec tively reduce consump tion and emissions .
A cold engine uses a disp roportionately high
amount of fue l. The e ngine reac hes operat ing
temperat ure and cons umption no rma lizes on ly
after app roxima tely 2 .5 m iles (4 km).
Check the tire pressure
To save f ue l, ma ke sure the ti res are always i n­
f lated to t he correct press ure
c> page 339. The
fuel consumpt io n can increase by 5% if the pres­
s ur e is on ly 0 .5 bar too low . Due to t he increased
r oll ing resis tance, low tire pressures w ill also
l ead to greate r tire
wear an d will affect dr iving
behav ior.
Do not d rive on
winter tires year- ro und , as this
will consume u p to 10% more f uel.
Eliminate unnecessary weight
S ince eve ry pou nd of ext ra weight inc reases fuel
consumption, a quick inspect io n of the luggage
compartment may be wo rth it to avoid un neces-
sary we ight .

Trail er to wing
Trailer towing
Driving with a trailer
General information
Your veh icle is primari ly intended for transport­
ing peop le and luggage. Howeve r, if you dr ive
with a tra iler , follow the techn ica l requirements ,
the operation and driving tips, and the lega l reg ­
ulations.
Dr iving w ith a trailer affects the vehicle 's fuel
consumpt ion, performance and wear. It a lso re­
quires higher concentration from the driver .
A WARNING
Do not transport any people in a trailer due to
the risk of fatal injury .
Technical requirements
Certain requirements must be met when towing
a trailer.
Trailer hitch
Only use a trailer hitch with a removab le ball
h itch mount and ball h itch. The tra ile r hitc h must
be pe rm it t ed for the vehicle, the tra iler and the
permitted tota l weight of the trailer being
pu lled . Above all, it must be secure ly and safe ly
attached to the vehicle trailer.
Never mo unt a t rai ler hitch on the bumper. The
trai ler hitc h must be mounted in a way that does
not impair the function of the bumper. Do not
make any changes to the exhaust system and the
brake system.
Check regu larly if the trai ler hitc h is securely
mounted . A lways follow the instructions given by
the trai ler hitch manufacturer .
Trailer brakes
If t he tra ile r has its own bra ke system, then fol­
low the manufacturer specifica tions. Howeve r,
the brake system on the trai ler must never be
connected to the vehicle brake system.
118
Engine cooling system
D riving w ith a tra ile r means a higher load on t he
engine and the cooling sys tem. The coo ling sys­
tem must be designed for additiona l load and
contain enoug h
coolant ¢@ .
@ Note
Longer incl ines cannot be driven wi tho ut a
suitab le cooling system, especia lly if the out ­
side temperatures are high . ot herwise, this
i ncreases the risk of eng ine damage.
Operating instructions
Several things must be noted when towing a
trailer.
Towing capacity
Yo ur vehicle can only be ope ra ted with class 1 or
class 2 trai le rs.
Load distribution
Poor cargo load and distr ib ution can negatively
i mpact vehicle handling . T o have the lowest im­
pact as poss ible, load the tra ile r according to
t h ese cr ite ria :
- Store objects preferably in the vehicle luggage
compartment . The vehicle should a lways carry
the heaviest poss ib le load and the trailer
should have t he lig htest poss ible load .
- Dist ribute the load in the t railer so that the
heavy objects a re as close to the axle as poss i­
ble.
- Secu re objects from s lid ing o ut of place.
- Ut il ize the maximum permitted tongue we ight
if poss ible .
Tire s
Set the tire pressure on your vehicle for a "full
load"; see the tire pressure
st icker ¢ page 341.
If necessary, also adjust the t ire pressure on the
trailer acco rding to the manufactu rer's recom­
mendat ion.
Winter tires should be mounted on the vehicle and on the trailer during w inter temperatures .

used .
This chapter contains important informat ion,
tips, instructions and warnings that you need to
read and observe for your own safety, the safety
of your passengers and others . We have summar­
iz ed here what you need to know about safety
belts, airbags, child restraints as well as child
safety. Your safety is for us
priority number 1. Al­
ways observe the information and warnings in
this section -for your own safety as well as that
of your passengers.

Driving safety
Important things to do before driving
Safety is everybody 's job ! Vehicle and occupant
safety always depends on the informed and care­
ful driver .
For your safety and the safety of your passen­
gers,
before driving always:
.. Make sure that a ll lights and signals are operat­
ing correctly.
.. Make sure tha t the tire pressure is correct .
.. Make sure that all w indows are clean and afford
good vis ibility to the outs ide.
.. Secure all luggage and othe r items ca refully
c::> page 63, c::> page 63 .
.. Make sure that nothing can interfere with the
peda ls .
.. Adjust front seat, head restraint and mirrors
correct ly for your height.
.. Instruct passengers to adjust the head re­
straints according to their height.
.. Make sure to use the right child restraint cor­
rectly to protect children
c::> page 294, Child
safety .
.. Sit properly in your seat and make sure t hat
your passengers do the same
c::> page 59, Front
seats .
.. Fasten your safety belt and wear it properly. Al­
so instruct your passengers to fasten their safe­
ty belts properly
c::> page 260.
What impairs driving safety?
Safe driving is directly related to the condition of
the vehicle , the driver as well as the driver 's abili­
ty to concentrate on the road without being dis­
tracted.
The driver is responsible for the safety of the ve ­
hicle and a ll of its occupants. If your ability to
drive is impa ired, safety risks for everybody in the
vehicle increase and you a lso become a hazard to
everyone else on the road
c::> &_ . Therefore:
.. Do not let yourse lf be distracted by passengers
or by using a cellular telephone .
.. NEVER drive when your driving abi lity is im­
pa ired (by med ications, alcohol, drugs, etc .) .
.. Observe all traffic laws, rules of the road and
speed lim its and plain common sense .

Drivin g saf ety
- After closing the rear lid, a lways make sure
that it is properly closed and locked.
- Never leave yo ur vehicle unattended espe­
c ia lly w ith the rear lid left open. A ch ild
could crawl into the ve hicle through the lug­
gage compartment and close the rear lid be­
coming trapped and unable to get out . Be­
ing t rapped in a veh icle can lead to se rious
persona l injury.
- Never let children play in or around the veh i­
cle .
- Never let passengers ride in the luggage
compartment. Ve hicle occupants m ust al­
ways be prope rly rest ra ined in one of the ve­
hicle's seating posi tions.
(D Tips
- A ir c irculat io n helps to reduce window fog­
g ing . Stale air escapes to the outside
th rough vents i n the t rim panel. Be s ure to
k eep these slots free and open.
- The t ire pressu re must correspond to the
l oad. The tire p ressure is shown on the tire
p ressure labe l. Th e tire pressu re labe l is lo ­
ca ted on t he driver 's s ide B-p illar. The tir e
p ressure labe l lists the recommended cold
tire inflation pressures for the vehicle at its max imum capacity weig ht and the t ires t hat
were on your vehicle at the t ime it was man­
ufactured. For recommended tire pressures
for normal load cond itions, please see chap­
ter
¢ page 341.
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 proper ly
¢ page 255, Loading the luggage compartment.
In a col lision, the laws of p hysics mean that even
sma ller items that are loose in the vehicle will
become heavy missiles that can cause ser ious in­
jury. Items in t he ve hicle possess energy which
vary with vehicle speed and the weight of the item . Veh icle speed is the most s ignificant factor .
For examp le, in a frontal collision at a speed of
30 mph (48 km/h), the forces act ing o n a 10-lb
256
(4.5 kg) object are about 20 times the normal
weight of the item . This means that the weight
of the item would s udden ly be about
200 lbs. (90 kg). You can imag ine the in juries
that a 200 lbs. (90 kg) item flying freely through
the passenger compartment could cause in a col­
l is ion like t his.
A WARNING
Weak, damaged or imp roper straps used to
secure items to tie-downs can fa il dur ing hard
b raking or in a coll is ion and cause ser io us pe r­
sona l injury .
- Always use s uitable mo unt ing st raps and
p roper ly sec ure i tems to the t ie -downs in
the l uggage compa rtment to help preven t
items from shifting or flying forward as dan ­
ge rous missi les .
- W hen the rear seat backrest is fo lded down,
a lways use s uitable mo unting straps and
properly sec ure items to the tie-downs in
the luggage compartment to help prevent items from flying forward as dangerous
m iss iles into the passenger compartment.
- Never attach a child safety seat tether strap
to a t ie-down.
