wash operator to reduce the risk of acci­ dents.
- To reduce the risk of cuts, protect yourself from sha rp metal components when wash­
ing the underbody or the inside of t he wheel
hous ings.
- After was hing the vehicle, the braking effect
may be delayed due to mo isture on the
bra ke rotors o r ice i n the winte r. This in­
c reases the risk of an a cciden t. The bra kes
must be dried first with a few care ful brake
applications .
@ Note
-If you wash the ve hicle in an automa tic car
wash, yo u must fold the exterior m irrors in
to reduce the risk of damage to the mirrors.
Power folding exterior mirrors * must on ly

- To reduce the risk of damage to the rims
and tires, compare the width between the
whee ls on your vehicle w ith the distance be­
tween t he gu ide rai ls in the car wash. -
To red uce the risk of damage, compare the
heig ht and width of your vehicle with the
heig ht and w idth of the inside of the car
wash.
- To prevent paint damage, do not wash the
vehicle in direct sunlight.
- To reduce the risk of damage to the surface,
do not use insect removing sponges, k itchen
sponges or s imilar items.
- Matte finish painted vehicle components:
- To reduce the r isk of damage to the sur-
face, do not use polishing agents or hard
wax.
- Never use protective wax. It can destroy
the matte finish effect.

finish paint. The paint could be damaged
when the stickers or magne ts are re­
moved.

Emerg ency assis ta nce
The vehicle jack mode* switches off automatical­
ly at speeds above 6 mph (10 km/h).
A WARNING
If you are changing a tire on a steep hill, use a
block or similar object to block the opposite

.,. Remove the cap with the plastic clip.
Loosening the wheel bolts
Fig . 263 Whee l: loosen ing t he whee l bolt
.. Slide the wheel wrench (from the vehicle tool
kit) all the way onto the wheel bolt .
.. Turn the wheel bolt approximately one turn to
the left -arrow- . To reach the required torque,
hold the end of the wheel wrench . If the wheel
bolt will not loosen, press ca refu lly on the
wheel wrench with your foo t. H old onto the ve­
hicle securely whi le dur ing th is and make sure
your stance is stable.

Removing a wheel
., Remove the top wheel bolt complete ly using
the hex socket in the screwdriver hand le (in the
vehicle tool kit)
c::> fig. 266 and place it on a
clean surface .
., Install the alignment pin (from the vehicle tool
kit) by hand into the empty hole
c::> fig. 267 .
., Remove the rest of the wheel bolts.
., Remove the wheel. The alignment pin remains
in the hole while doing this.
Install a wheel
Read the directions on c:> page 348 when instal­
ling unidirectional tires.
., Slide the wheel on over the alignment pin.
., Install the wheel bolts and tighten gent ly using
the hex socket.
., Remove the alignment pin and also tighten the
remaining wheel bo lt .
., Carefully lower the vehicle using the vehicle
jack* .
., Tig hte n the wheel bolts i n a diagona l pattern
using the wheel wren ch.
348
The wheel bolts must be clean and loosen/tight ­
en easily . Check the contact surfaces for the
wheel and hub. Contam inants on these surfaces
must be removed before installing the wheel.
A WARNING
Never use the hex socket in the screwdriver
handle or the hex socket wrench w ith the
ratchet to loosen or tighten the wheel bolts.
This increases the risk of an accident, because
you will not reach the tightening specification
required.
(D Note
When removing or instal ling the wheel, the
r im could hit the brake rotor and damage t he
rotor. Work carefully and have a second per­
son help yo u.
@ Tips
- When mounting tires with unidirectional
tread design
make sure the tread pattern is
pointed the right way
c::> page 348.
- The wheel bolts should be clean and easy to
turn. Check for dirt and corrosion on the
mati ng surfaces of both the wheel and the
hub. Remove all dirt from these sur faces be­
fore remounting the whee l.
Unidirectional tires
A unidirectional tire profile is identified by arrows
that point in the running direction on the tire
s idewall. You must always adhere to the speci­
fied running direction . Th is is necessary ensure
the tire's opt imum performance in regard to ad­
hesion, running noise, friction and hyd roplaning.
To benefit fully from the advantages of the uni­
directional tire design, you should replace faulty
tires as soon as possible and restore the correct
r un ning direction on all of the tires.
Finishing
., Re install the caps on the wheel bolts if neces­
sary .
., Store the vehicle tool kit in its designated
place . ..,.

When jump starting or charging the battery,
never connect the negative ground cable to
the battery negative post because the battery
manager system must be able to detect the
battery's state of charge . Always connect the
negative ground cable to the negat ive ground
post of the battery manager control unit .
Using the jump start
cable
Both jump start cables must be connected in the
correct order!

The procedure described below for connecting
jumper cables is intended to provide a jump start
for your vehicle.
Vehicle with discharged battery
.. Turn off lights and accessories, move automatic
transmission lever to N (Neutral) or P (Park)
and set parking brake .
Emergency situations
Connecting the positive cable (red) to the
po sitive terminal
.. Open the red cover on the positive terminal
r=>fig.274 .
1. Secure one end of the positive cable (red) to
the jump start pin
r=> fig. 275 (D (pin under
the red cover = "posit ive") on the vehicle that
needs to be started @.
2. Secure the other end of the pos itive cable
(red) to the positive termina l@ on the bat­
tery provid ing the current @.
Connecting the negative cable (black) to the
negative terminal
3. Secure one end of the black negat ive cab le to
the negative terminal @on the battery that
i s p roviding the current@.
4. Secure the other end of the negative cable
(black) to the jump start pin@ (hex head pin
= "negative") on the vehicle that needs to be
started @.
Starting the engine
.. Start the engine on the vehicle providing the
jump start @and let it run at idle .
.. Now start the engine on the vehicle with the
drained battery @ .
.. If the engine does not start, stop the starting
procedure after 10 seconds and then repeat it
after approx imately 30 seconds .
.. Remove the cables when the engines are run­
ning. Remove them in reverse order from the
way they were installed.
.. Close the red cover on the positive terminal.
T he battery is vented to the outside to prevent
gases from enter ing the vehicle interior . Make
s ur e that the jumper clamps are well connected
with their
metal ports in full contact with the
battery terminals.
_& WARNING
-To avoid serious personal injury and damage to the vehicle, heed all warnings and instruc ­
tions of the jumper cable manufacturer. If in
doubt, call for road service.
- Jumper cables must be long enough so that
the vehicles do not touch . ..,_
