To install a “LATCH” type child seat, the mounts (1) 
must be folded forward until they lock in place. To do so, 
grip inner side of mounts and fold forward. Install child 
seat according to the manufacturer’s instructions.
The child seat must be firmly attached in the right and 
left side mounting fittings (1).
To fold mounts (1) back, press down button (2) on each 
mount and return mount into its catch.
Non-“LATCH” type child seats may also be used and are 
capable of being installed using the vehicle’s seat belt 
system. Install child seat according to the 
manufacturer’s instructions.
Wa r n i n g !
The “LATCH” mounting fittings are intended for 
children up to 22 kg (50 lbs) in weight.Children too big for child restraint systems must 
ride in back seats using regular seat belts. Position 
shoulder belt across chest and shoulder, not face or 
neck. A booster seat may be necessary to achieve 
proper belt positioning for children from 41 lbs. to 
the point where a lap / shoulder belt fits properly 
without one.Before installing the child seat, make sure the 
mounting fittings (1) are folded out and locked in 
place.Install child seat according to manufacturer’s 
instructions.The child seat must be firmly attached in the right 
and left side mounting fittings (1).An incorrectly mounted child seat may come loose 
during an accident.Damaged or impact damaged child seats or child 
seat mounting fittings must be replaced.Do not leave children unattended in the vehicle, 
even if the children are secured in a child restraint 
system.

Loading instructions
The total load weight including vehicle occupants and 
luggage/cargo should not exceed the vehicle capacity 
weight indicated on the certification tag which can be 
found on the left door pillar.
The handling characteristics of a fully loaded vehicle 
depend greatly on the load distribution. It is therefore 
recommended to load the vehicle according to the 
illustrations shown, with the heaviest items being 
placed towards the front of the vehicle.
Always place items being carried against front or rear 
seat backrests, and fasten them as securely as possible.The heaviest portion of the cargo should always be kept 
as low as possible since it influences the handling 
characteristics of the vehicle.
Note:
The trunk is the preferred place to carry objects.
The enlarged cargo area should only be used for items 
which do not fit in the trunk alone.
Wa r n i n g !
Always fasten items being carried as securely as 
possible.In an accident, during hard braking or sudden 
maneuvers, loose items will be thrown around 
inside the vehicle, and can cause injury to vehicle 
occupants unless the items are securely fastened in 
the vehicle.To help avoid personal injury during a collision or 
sudden maneuver, exercise care when transporting 
cargo.Never drive vehicle with tailgate open. Deadly 
carbon monoxide (CO) gases may enter vehicle 
interior resulting in unconsciousness and death.

cluster displayPractical hintsCar care Index Tire inflation pressure
A table (see fuel filler flap) lists the tire inflation 
pressures specified for Mercedes-Benz recommended 
tires as well as for the varying operating conditions.
Important!
Tire pressure changes by approximately 1.5 psi (0.1 bar) 
per 18
°F (10
°C) of air temperature change. Keep this in 
mind when checking tire pressure inside a garage – 
especially in the winter.
Example:
If garage temperature = approximately +68
°F (+20
°C) 
and ambient temperature = approximately +32
°F (0
°C) 
then the adjusted air pressure = specified air pressure 
+3 psi (+0.2 bar).
Tire pressures listed for light loads are minimum values 
offering high driving comfort. Increased inflation 
pressures for heavy loads produce favorable handling 
characteristics with lighter loads and are perfectly 
permissible. The ride of the vehicle, however, will 
become somewhat harder.
Tire temperature and pressure increase with the vehicle 
speed. Tire pressure should therefore only be checked 
and corrected on cold tires. Correct tire pressure in warm tires only if pressure has dropped below the 
pressure listed in the table and the respective operating 
conditions are taken into consideration.
An underinflated tire due to a slow leak (e.g. due to a 
nail in the tire) may cause damage such as tread 
separation, bulging etc. Regular tire pressure checks 
(including the spare tire) at intervals of no more than 
14 days are therefore essential.
If a tire constantly loses air, it should be inspected for 
damage.
The spare tire should be checked periodically for 
condition and inflation. Spare tire will age and become 
worn over time even if never used, and thus should be 
inspected and replaced when necessary.
Wa r n i n g !
Do not overinflate tires. Overinflating tires can 
result in sudden deflation (blowout) because they 
are more likely to become punctured or damaged 
by road debris, potholes etc. Follow recommended 
inflation pressures.Do not overload the tires by exceeding the specified 
vehicle capacity weight as indicated by the label on 
the driver’s door latch post). Overloading the tires 
can overheat them, possibly causing a blowout.
