&WARNING Risk of accident and injury
when opening and closing the engine
hood
When opening or closing the engine hood, it
may suddenly drop into the end position.
There is a risk of injury for an yone in the
engine hood's range of mo vement.
#Only open or close the engine hood
when there are no persons in the
engine hood's range of mo vement.
&
WARNING Danger of burn s when open‐
ing the hood
If yo u open the hood when the engine has
ove rheated or during a fire inthe engine
compartment, you could come into contact
wit h hot gases or other escaping operating
fl uids.
#Before opening the hood, allow the
engine tocool down.
#Intheeve nt of a fire inthe engine com‐
partment, keep the hood closed and
call thefire service.
&
WARNING Risk of injury duetomoving
parts
Cer tain components in the engine compart‐
ment may continue tomo veor suddenly
mo veagain even af terth e ignition has been
switched off, e.g. the cooler fan.
Make sure of thefo llowing before per form ing
ta sks in the engine compartmen t:
#Switchthe ignition off.
#Ne verto uch the danger zone sur round‐
ing moving co mponent parts, e.g. the
ro tation area of thefa n.
#Re mo vejewe lry and watches.
#Keep items of clo thing and hair away
from moving parts.
& WARNING Risk of injury fromtouching
co mp onent parts under voltage
The ignition sy stem and the fuel injection
sy stem workunder high voltage. If youto uch
co mp onent parts which are under voltage,
yo u could receive an electric shoc k.
#Neverto uch co mponent parts of the
ignition sy stem or the fuel injection sys‐
te m when the ignition is switched on.
&
WARNING Risk of burn s from hot com‐
ponent parts in the engine compartment
Cer tain component parts in the engine com‐
partment can be very hot, e.g. the engine,
th e cooler and parts of theex haust sy stem.
#Let the engine cool down and only

WARNING Risk of accident caused by
re peated drop in tire pressure
If th e tire pressure drops repeatedly, the
wheel, valve or tire may be damaged.
Insuf ficient tire pressure can cause the tires
to bur st.
#Inspect the tire for signs of fore ign
objects.
#Check whe ther the wheel or valve has a
leak.
#If yo u are unab leto rectify the damage,
conta ct aqualified specialist workshop.
Yo u can find information on tire pressures for
th eve hicle's factor y-ins talled tires on thefo llow‐
ing labels:
RTi re and Loading Info rmation placard on the
B‑pillar of your vehicle (→page 369).
RTire pressure table on the inside of the fuel
fi ller flap (→page 364). Observ
eth e maximum tire pressure
(
→page 375).
Us e a suitabl epressu regauge tocheck the tire
pressure. The outer appearance of a tire does
not permit any reliable conclusion about the tire
pressure.
Ve hicles with a tire pressure monitoring sys‐
te m: You can also check the tire pressure using
th e on-board computer.
Only cor rect tire pressures when the tires are
cold. Conditions for cold tires:
RThe vehicle has been par ked with the tires
out of direct sunlight for at least thre e hours.
RThe vehicle has tr aveled less than 1 mile
(1.6 km).
A rise in the tire temp erature of 18°F (10 °C)
increases the tire pressure byappr ox.10 kPa
(0.1 bar/1.5 psi). Take this into account when
ch ecking the tire pressure of warm tires.
The tire pressure sre commended for increased
load/speed in the tire pressure table can af fect
th eride comfort.
&
WARNING Risk of accident from unsuita‐
ble accessori es onthe tire valves
If yo u mount unsuitable accessories onto tire
va lves, the tire valves may be overloaded and
malfunction, which can cause tire pressure
loss. Tire pressure monitoring sy stems for
re trofitting will cause the tire valve toremain
open. This can also result in tire pressure
loss.
#Only scr ewstandard valve caps or valve
caps specifically appr ovedby
Mercedes-Benz foryo ur vehicle onto
th e tire valve.

Uniform Tire Quality Grading Standards: a
uniform standard tograde thequ ality of tires
with rega rd totread quality, tire traction and
te mp erature characteristics. The quality grading
assessment is made bythe manufacturer follow‐
ing specifications from theU. S. go vernment. The
qu ality grade of a tire is imprinted on the side
wa ll of the tire.
Re commended tire pressure :th ere commen‐
ded tire pressure is the tire pressure specified
fo rth e tires mounted totheve hicle at thefa c‐
to ry.
The tire and information table conta insthere c‐
ommended tire pressures for cold tires, the max‐
imum permissible load and the maximum per‐
missible vehicle speed.
The tire pressure table conta insthere commen‐
ded tire pressures for cold tires under various
operating conditions, i.e. loading and/or speed
of theve hicle.
Increased vehicle weight due tooptional
equipment: the combined weight of all standard
and optional equipment available forth eve hicle, re
ga rdless of whe ther it is actually ins talled on
th eve hicle or not.
Rim: the part of the wheel on which the tire is
ins talled.
GA WR (Gross Axle Weight Rating): the GAWR
is the maximum permissible axle load. The
actual load on an axle must ne verexc eed the
gros s axle weight rating. The gross axle
weight
ra ti

ng can be found on theve hicle identification
plate on the B‑pillar on the driver's side.
Speed rating: the speed rating is pa rtof the tire
identification. It specifies the speed range for
which a tire is appr oved.
GV W (Gross Vehicle Weight): the gross vehicle
we ight comprises thewe ight of theve hicle
including fuel, tools, the spare wheel, accesso‐
ri es ins talled, occupants, luggage and the trailer
dr aw bar nose weight, if applicable. The gross
ve hicle weight must not exceed the gross vehicle
we ight rating GVWR as specified on theve hicle
identification plate on the B‑pillar on the driver's
side.
GV WR (Gross Vehicle Weight Rating): the
GV WR is the maximum permitted gross weight of
the fully laden vehicle (weight of theve hicle
including all accessories, occupants, fuel, lug‐
ga ge and the trailer dr awbar nose weight if appli‐
cable). The grossve hicle weight rating is speci‐
fi ed on theve hicle identification plate on the
B‑pillar on the driver's side.
Maximum weight of the laden vehicle: the
maximum weight is the sum of the curb weight
of theve hicle, thewe ight of the accessori es,the
maximum load and thewe ight of optional equip‐
ment ins talled at thefa ctor y.
Kilopascal (kPa): metric unitfor tire pressure .
6.9 kPa cor responds to1 psi. Ano ther unit for
tire pressure is bar.
10 0 ki
lopascal (kPa) equals
1 bar.
Load index: in additiontothe load-bearing
index, the load index may also be imprinted on
th e side wall of the tire. This specifies the load-
bearing capacity of the tire more precisel y.
Curb weight: thewe ight of a vehicle with stand‐
ard equipment including the maximum capacity
of fuel, oil and coolant. It also includes the air
conditioning sy stem and optional equipment if
