forwards in the direction of the arrow until
it engages.
There are several notches. X
To move backwards: press and hold
release button C and push the head
restraint backwards. X
When the head restraint is in the desired
position, release the button and make sure
that the head restraint is engaged in posi-
tion.

Problems with the seat heating Problem
Possible causes/consequences and P Solutions
The seat heating has
switched off prema-
turely or cannot be
switched on. The on-board voltage is too low because too many electrical con-
sumers are switched on. X
Switch off electrical consumers that you do not need, such as
the rear window defroster or interior lighting.
Once the battery is sufficiently charged, the seat heating will
switch back on automatically.
Steering wheel
Important safety notes
G WARNING
You could lose control of your vehicle if you do
the following while driving: R
adjust the driver's seat, head restraint,
steering wheel or mirrors R
fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt
before starting the engine.
G WARNING
Children could injure themselves if they
adjust the steering wheel. There is a risk of
injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
Adjusting the steering wheel
G WARNING
If the steering wheel is unlocked while the
vehicle is in motion, it could change position
unexpectedly. This could cause you to lose
control of the vehicle. There is a risk of an
accident. Before starting off, make sure the steering
wheel is locked. Never unlock the steering
wheel while the vehicle is in motion.

Parking tips: R
On narrow roads, drive as close to the park-
ing space as possible. R
Parking spaces that are littered or over-
grown might be identified or measured
incorrectly. R
Parking spaces that are partially occupied
by trailer drawbars might not be identified
as such or be measured incorrectly. R
Snowfall or heavy rain may lead to a parking
space being measured inaccurately. R
Pay attention to the PARKTRONIC
( Y
page 193) warning messages during the
parking procedure. R
You can intervene in the steering procedure
to correct it at any time. Active Parking
Assist will then be canceled. R
When transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist. R
Never use Active Parking Assist when snow
chains are installed. R
Make sure that the tire pressures are
always correct. This has a direct influence
on the parking characteristics of the vehi-
cle.
Use Active Parking Assist for parking spaces: R
that are parallel or at right-angles to the
direction of travel R
that are on straight roads, not bends R
that are on the same level as the road, e.g.
not on the pavement
Detecting parking spaces
Objects located above the height range of
Active Parking Assist will not be detected
when the parking space is measured. These
are not taken into account when the parking
procedure is calculated, e.g. overhanging
loads, tail sections or loading ramps of goods
vehicles. G WARNING
If there are objects above the detection range: R
Active Park Assist may steer too early R
the vehicle may not stop in front of these
objects
You may cause a collision as a result. There is
a risk of an accident.
If objects are located above the detection
range, stop and deactivate Active Parking
Assist.
For further information on the detection
range ( Y
page 192).
Active Parking Assist does not assist you
parking in spaces at right angles to the direc-
tion of travel if: R
two parking spaces are located directly
next to one another R
the parking space is directly next to a low
obstacle such as a low curb R
you park forwards
Active Parking Assist does not assist you
parking in spaces that are parallel or at right
angles to the direction of travel if: R
the parking space is on a curb R
the system reads the parking space as
being blocked, for example by foliage or
grass paving blocks R
the area is too small for the vehicle to
maneuver into R
the parking space is bordered by an obsta-
cle, e.g. a tree, a post or a trailer

lated by dividing the tire width by the tire
height.
Tire code: tire code

Curb weight
The weight of a vehicle with standard equip-
ment including the maximum capacity of fuel,
oil and coolant. It also includes the air-condi-
tioning system and optional equipment if
these are installed in the vehicle, but does not
include passengers or luggage.
Maximum load rating
The maximum tire load is the maximum per-
missible weight in kilograms or lbs for which a
tire is approved.
Maximum permissible tire pressure
Maximum permissible tire pressure for one
tire.
Maximum load on one tire
Maximum load on one tire. This is calculated
by dividing the maximum axle load of one axle
by two.
PSI (pounds per square inch)
A standard unit of measure for tire pressure.
Aspect ratio
Relationship between tire height and tire
width in percent.
Tire pressure
This is pressure inside the tire applying an
outward force to each square inch of the tire's
surface. The tire pressure is specified in
pounds per square inch (psi), in kilopascal
(kPa) or in bar. The tire pressure should only
be corrected when the tires are cold.
Cold tire pressure
The tires are cold: R
if the vehicle has been parked with the tires
out of direct sunlight for at least three
hours and R
if the vehicle has not been driven further
than 1 mile (1.6 km) Tread
The part of the tire that comes into contact
with the road.
Bead
The tire bead ensures that the tire sits
securely on t h
e wheel. There are several steel
wires in the bead to prevent the tire from
coming loose from the wheel rim.
Sidewall
The part of the tire between the tread and the
bead.
Weight of optional extras
The combined weight of those optional extras
that weigh more than the replaced standard
parts and more than 2.3 kg (5 lbs). These
optional extras, such as high-performance
brakes, level control, a roof rack or a high-
performance battery, are not included in the
curb weight and the weight of the accesso-
ries.
TIN (Tire Identification Number)
This is a unique identifier which can be used
by a tire manufacturer to identify tires, for
example for a product recall, and thus identify
the purchasers. The TIN is made up of the
manufacturer's identity code, tire size, tire
type code and the manufacturing date.
Load bearing index
The load bearing index (also load index) is a
code that contains the maximum load bearing
capacity of a tire.
Traction
Traction is the result of friction between the
tires and the road surface.
Treadwear indicators
Narrow bars (tread wear bars) that are dis-
tributed over the tire tread. If the tire tread is
level with the bars, the wear limit of

R
Before raising the vehicle, secure it from
rolling away by applying the parking brake
and inserting wheel chocks. Do not disen-
gage the parking brake while the vehicle is
raised. R
The jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a
large, flat, load-bearing underlay must be
used. On a slippery surface, a non-slip
underlay must be used, e.g. rubber mats. R
Do not use wooden blocks or similar
objects as a jack underlay. Otherwise, the
jack will not be able to achieve its load-
bearing capacity due to the restricted
height. R
Make sure that the distance between the
underside of the tires and the ground does
not exceed 1.2 in (3 cm). R
Never place your hands and feet under the
raised vehicle. R
Do not lie under the vehicle. R
Do not start the engine when the vehicle is
raised. R
Do not open or close a door or the trunk lid
when the vehicle is raised. R
Make sure that no persons are present in
the vehicle when the vehicle is raised.
Vehicles with steel wheels: the hub cap
covers the wheel bolts. Before you can
unscrew the wheel bolts, you must remove
the hub caps.
X
Using both hands, carefully reach into two
hub cap openings and remove the hub cap. X
Using lug wrench C , loosen the bolts on
the wheel you wish to change by about one
full turn. Do not unscrew the bolts com-
pletely.
Jacking points
The jacking points are located just behind the
front wheel housings and just in front of the
rear wheel housings (arrows).
Mercedes-AMG vehicles and vehicles
with AMG equipment: to protect the vehicle
body, the vehicle has covers installed next to
the jacking points on the outer sills.
