There is a risk of an accident and injury.
Never leave children or animals unattended
in the vehicle.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. This
also applies for the Digital Vehicle Key if the
"Digital Vehicle Key" function is activated via
Mercedes me connect.
GDANGER
Combustion engines emit poisonous
exhaust gases such as carbon monoxide.
Inhaling these exhaust gases is hazardous to
health and can result in poisoning. There is a
risk of fatal injury. Therefore, never leave the
engine running an enclosed space without
adequate ventilation.
GWARNING
Flammable materials introduced through
environmental influence or by animals can
ignite if in contact with the exhaust system
or parts of the engine that heat up. There is
a risk of fire.
Carry out regular checks to make sure that
there are no flammable foreign materials in
the engine compartment or in the exhaust
system.
The catalytic converter is preheated for up to30 seconds after a cold start. The sound of theengine may change during this time.

Starting procedure with the SmartKey
To start the engine using the SmartKey insteadof KEYLESS-GO, pull the Start/Stop button outof the ignition lock.
XTurn the SmartKey to position I(Ypage 126) in the ignition lock and releaseit as soon as the engine is running.
Using KEYLESS-GO to start the engine
The Start/Stop button can be used to start thevehicle manually without inserting the Smart-Key into the ignition lock. The Start/Stop but-ton must be inserted in the ignition lock andthe SmartKey must be in the vehicle. Thismode for starting the engine operates inde-pendently of the ECO start/stop automaticengine start function.
XDepress the brake pedal and keep itdepressed.
XPress the Start/Stop button once(Ypage 126).The engine starts.
Pulling away
General notes
GWARNING
If the engine speed is above the idling speed
and you engage transmission position :
or F, the vehicle could pull away sud-
denly. There is a risk of an accident.
When engaging transmission position :
or F, always firmly depress the brake
pedal and do not simultaneously accelerate.
Depress the accelerator carefully when pullingaway.
The vehicle locks centrally once you havepulled away. The locking knobs in the doorsdrop down.
You can open the doors from the inside at anytime.
You can also deactivate the automatic lockingfeature (Ypage 201).

It is only possible to shift the transmissionfrom position ]to the desired position if youdepress the brake pedal. Only then is the shiftlock released.
iUpshifts take place at higher enginespeeds after a cold start. This helps the cat-alytic converter to reach its operating tem-perature more quickly.

Hill start assist
Hill start assist helps you when pulling awayforward or in reverse on an uphill gradient. Itholds the vehicle for a short time after youhave removed your foot from the brake pedal.This gives you enough time to move your footfrom the brake pedal to the accelerator pedaland to depress it before the vehicle begins toroll.
GWARNING
After a short time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is a risk of an accident and injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not active if:
Ryou are pulling away on a level road or on adownhill gradient
Rthe transmission is in position \\
Rthe electric parking brake is applied
RESP®is malfunctioning
ECO start/stop function
Introduction
The ECO start/stop function switches theengine off automatically if the vehicle is stop-ped under certain conditions.
The engine starts automatically when thedriver wants to pull away again. The ECOstart/stop function thereby helps you toreduce the fuel consumption and emissions ofyour vehicle.
Important safety notes
GWARNING
If the engine is switched off automatically
and you exit the vehicle, the engine is
restarted automatically. The vehicle may
begin moving. There is a risk of accident and
injury.
If you wish to exit the vehicle, always turn
off the ignition and secure the vehicle
against rolling away.
General notes
CECO start/stop display
The ECO start/stop function is activatedwhenever you switch on the engine using theSmartKey or the Start/Stop button.

All vehicles (except Mercedes-AMG vehi-cles):automatic engine switch-off can takeplace a maximum of four times in a row (initialstop, then three subsequent stops).
Mercedes-AMG vehicles:the number of con-secutive automatic engine switch-offs isunlimited.

ProblemPossible causes/consequences and P PSolutions
The engine is not run-ning smoothly and ismisfiring.
There is a malfunction in the engine electronics or in a mechanicalcomponent of the engine management system.
XOnly depress the accelerator pedal slightly.Otherwise, non-combusted fuel may get into the catalytic con-verter and damage it.
XHave the cause rectified immediately at a qualified specialistworkshop.
The coolant tempera-ture display shows avalue above 248 ‡(120 †). The coolantwarning lamp may alsobe on and a warningtone may sound.
The coolant level is too low. The coolant is too hot and the engine isno longer being cooled sufficiently.
XStop as soon as possible and allow the engine and the coolant tocool down.
XCheck the coolant level (Ypage 267). Observe the warning notesas you do so and add coolant if necessary.
If the coolant level is correct, the engine radiator fan may be faulty.The coolant is too hot and the engine is no longer being cooled suf-ficiently.
XAt coolant temperatures below 248 ‡ (120 †), drive to the near-est qualified specialist workshop.
XAvoid heavy loads on the engine as you do so, e.g. driving inmountainous terrain and stop-and-go traffic.
Notes on towing vehicles
The vehicle is not suitable for attaching towbar systems, such as those used for flat tow-ing or dinghy towing.
Attaching or using tow bar systems may resultin damage to the vehicle.
When towing a vehicle with tow bar systems,safe driving characteristics cannot be guaran-teed for the towing vehicle or the towed vehi-cle.
The vehicle/vehicle combination may swerve.
Observe the permissible towing methods(Ypage 289) and the notes on towing withboth axles on the ground (Ypage 289).
