 
Driving with an open luggage compartment lid can lead to serious personal injury. If you have to drive 
with an open luggage compartment lid, make sure that all objects and the lid itself are properly 
secured and take appropriate measures to keep toxic exhaust fumes from entering the vehicle. 
  WARNING 
Driving with an unlatched or open luggage compartment lid can lead to serious personal 
injury. 
 x Never transport objects larger than those that fit completely in the luggage compartment, 
because the luggage compartment lid cannot be fully closed properly. 
 x After closing the lid, always pull up on it to make sure that it is properly closed and cannot 
open suddenly when the vehicle is moving. 
 x Always stow all objects securely in the luggage compartment. Loose objects can fall out 
of the luggage compartment and injure others on the road behind you. 
 x Drive carefully; anticipate what other drivers will do. 
 x Avoid abrupt or sudden acceleration, steering, or braking, because the unlatched luggage 
compartment lid can move suddenly. 
 x Always mark objects sticking out from the luggage compartment clearly for others to see. 
Obey all applicable legal requirements. 
 x Never use the luggage compartment lid to “clamp” or “hold” objects that stick out of the 
luggage compartment. 
 x Always remove any luggage rack or other rack mounted on the luggage compartment lid 
(along with any luggage on the rack) before driving with an open luggage compartment lid.  
  WARNING 
Driving with an open luggage compartment lid can cause poisonous carbon monoxide in the 
engine exhaust to get into the passenger compartment. 
 x Carbon monoxide causes drowsiness, inattentiveness, poisoning, and loss of 
consciousness. It can lead to accidents and severe personal injuries. 
 x Always keep the luggage compartment lid closed while driving to help keep poisonous 
exhaust fumes from being drawn into the vehicle. 
 x Never transport objects that are too large to fit completely into the luggage area, because 
then the luggage compartment lid cannot be fully closed. 
 x If you absolutely must drive with an open luggage compartment lid, do the following to 
reduce the risk of carbon monoxide poisoning: 
 – Close all windows and the power sunroof. 
 – Switch off the climate control system's air recirculation feature. 
 – Open all air vents in the instrument panel. 
 – Set the fresh air fan to the highest speed.  
  NOTICE 
The open luggage compartment lid changes the vehicle height. 
Driving a loaded vehicle 
 

 
causes you to run off the road before ESC can provide any assistance, you may not experience the 
benefits of ESC. 
ESC includes and/or works together with the ABS, BAS, ASR, EDL, and XDL systems (see below). 
ESC is switched on all the time. In certain situations when you need less traction or additional traction 
cannot be achieved, you can switch off ASR by pressing the  m button ⇒ fig. 122. Be sure to switch 
ASR on again when you no longer need less traction. 
Anti-Lock Brake System (ABS) 
ABS helps to keep the wheels from locking up and helps to maintain the driver's ability to steer and 
control the vehicle. This means the vehicle is less likely to skid, even during hard braking: 
 x Push the brake pedal down hard and hold it there. Don't take your foot off the pedal or reduce the 
force on the pedal! 
 x Do not “pump” the brake pedal or let up on it! 
 x Steer the vehicle while pushing down hard on the brake pedal. 
 x ABS stops working if you release or let up on the brake. 
When ABS is doing its job, you will notice a slight vibration through the brake pedal and hear a 
noise. ABS cannot shorten the stopping distance under all conditions. The stopping distance may 
even be longer, for instance, when driving on gravel or on newly fallen snow covering an icy or 
slippery surface. 
Brake Assist (BAS) 
The Brake Assist System can help to reduce stopping distances. If you press the brake pedal very 
quickly, BAS detects an emergency situation. It then very quickly builds up full brake system pressure, 
maximizing braking power and reducing the stopping distance. This way, ABS can be activated more 
quickly and efficiently. 
Do not reduce pressure on the brake pedal! BAS switches off automatically as soon as you release or 
let up on the brake. 
Anti-Slip Regulation (ASR) 
ASR reduces engine power directed to spinning wheels and adjusts power to the road conditions. 
Even under poor road conditions, ASR can make it easier to get moving, accelerate, and climb hills. 
ASR can be switched on or off manually   
Electronic Differential Lock (EDL and XDL) 
EDL is applied during regular straight-line acceleration. EDL gently brakes a drive wheel that has lost 
traction (spinning) and redirects the drive force to other drive wheels. In extreme cases, EDL 
automatically switches off to keep the brake from overheating. As soon as the brake has cooled down, 
EDL automatically switches on again. 
XDL is an extension of the Electronic Differential Lock system. XDL does not react to drive wheel 
slippage when driving straight ahead. Instead, XDL detects slippage of the inside front wheel during 
fast cornering. XDL applies enough brake pressure to this wheel in order to stop the slippage. This 
improves traction, which helps the vehicle stay on track.
