&WARNINGRisk of accident when switch‐ing offthe ignition when driving
Ifyou switchoffthe ignition while driving,safety functions arerestricted or no longeravailable. This may affectthe powersteeringsystem andthe brakeforce boosting,forexample.
You willthen needtouse considerably moreforcetosteer and brake.
#Do not switch offthe ignition while driv‐ing.
&DANGERRisk offatal injuries duetoexhaustgases
Combustion engines emit poisonousexhaustgases such as carbon monoxide. Inhalingtheseexhaustgases is hazardoustohealthand can leadtopoisoning.
#Never leavethe enginerunning in anenclosed space without sufficientventi‐lation.
&WARNINGRisk of skidding and of anaccident duetoshifting down on slipperyroad surfaces
Ifyou shift down on slipperyroad surfacestoincreasethe engine braking effect,the drivewheels may lose traction.
#Do not shift down on slipperyroad sur‐facestoincreasethe engine brakingeffect.
&DANGERRisk offatal injury duetopoi‐sonousexhaustgases
Ifthetailpipe is blocked or sufficientventila‐tion is not possible, poisonousexhaustgasessuch as carbon monoxide may enterthevehi‐cle. This isthe case ifthevehiclegetsstuckin snow,forexample.
#Keepthetailpipe andthe area aroundthevehicle free from snow whentheengine orthestationary heater arerun‐ning.

RThevehicle isstabilizedbymeans of individ‐ual brake application on one side.
Function of EBD (electronic brakeforce dis‐tribution)
EBD ischaracterizedbythefollowing:
RMonitoring andregulatingthe brake pressureontherear wheels.
RImproved drivingstability when braking,especially on bends.
Function ofSTEER CONTROL
STEER CONTROL helpsyoubytransmitting anoticeablesteeringforcetothesteering wheel inthe directionrequiredforvehiclestabilization.

&WARNINGRisk of an accident duetoinsufficient tire pressure
Tirepressuresthat aretoo low posethefollowing hazards:
RThe tires may burst, especially asthe load andvehicle speed increase.
RThe tires maywearexcessively and/or unevenly,which may greatly impair tire traction.
RThe drivingcharacteristics, aswell assteering and braking, may be greatly impaired.
You couldthen lose control ofthevehicle.
#Observetherecommended tire pressure.
#Adjustthe tire pressure if necessary.
#Stopthevehicle, paying attentiontoroad and traffic conditions.
#Checkthe tire pressure (→page 435) andthe tires.

Please Correct Tire Pres-sure
*The tire pressure istoo low in at least one ofthe tires, orthe tire pressure difference betweenthe wheels istoogreat.
#Checkthe tire pressure and add air, if necessary.
#Whenthe tire pressure is correct,restartthe tire pressure monitoring system (→page441).
