~ &.
- Turn the ignition key to position @~ fig. 132 -do not
depress the gas pedal when starting the engine.
A cold engine may sound loud after it has been started. This is due to
the hydraulic valves building up oil pressure. This is normal and is not
a need for concern.
If the engine does not start immediately, stop trying after 10 seconds
and then try to restart the engine about 30 seconds later .
& WARNING
Never start or let the engine run in a confined or enclosed area.
Exhaust fumes from the engine contain carbon monoxide , a color­
less and odorless gas. Carbon monoxide can be fatal if inhaled.
• Never leave the engine idling unattended. An unattended
vehicle with a running engine poses a danger of personal injury or
theft .
0 Note
• Avoid high eng ine speeds, fast accelerat io n or heavy engine loads
wh ile the engine is still cold. This could damage the engine.
• The engine cannot be started by push ing or towing the vehicle.
~ For the sake of the environment
To avoid unnecessary engine wear and to reduce exhaust emissions,
do not let your vehicle stand and warm up. Be ready to drive off imme­
diately after starting your vehicle. Maintain moderate speed unti l the
engine is completely warm. Remember, the engine performs best at
operating temperature .•

& W ARNING (continued )
• Never park the vehicle where it can come in contact with dry
grass , spilled fuel or any other flammable material s.
• When parking on hills, always turn the wheel s so that the front
wheel s will fir st roll into the curb, if the vehicle should start to
roll.
• Never allow anyone · especially small children· to remain in
the vehicle when it i s locked. Locked door s make it more difficult
fo r rescu ers to acce ss the passenger compartment in the event of
an emergency. Danger to life!
• Never leave children unsuperv ised in the vehicle. Ch ildren
could relea se the parking brake or move the gear shift lever out of
gear. The vehicle could start to roll away and cau se an accident .
• No matter what the season i s, the temperature
in a parked
v ehicle can reach dangero us le vels .
0 Note
• Please exercise care when you pa rk your veh icle in parking areas
w ith park ing barriers o r cur bs. Parking barriers and curbs vary in
he ight and could damage your bumpe r and related components as
the front of your vehicle moves over a ba rrier or curb that is too high,
as you park or as you back out of a pa rking spot. In order to be sure
that no such damage can occur, yo u may wish to stop short of having
t he fro nt t ires of you r car touch t he p arking bar rie r or curb.
• Please a lso exerc ise except iona l care when you drive up or down
steep ramps or drive over curbs or o ther obstacles, for which the
vehicle is not des igned, because components of the vehicle close to
t he ground, s uch as bumpe r covers, spoilers and suspension and
exhaust system components, may become damaged. •

Starting off with a trailer
To prevent rolling back unintentionally on an incline, do
the following:
- Keep the switch pulled and depress the accelerator. The
parking brake stays applied and p reve nts the vehicle from
rolling backward .
- You can release t he switch once you are sure t hat you are
deve loping enough forward momentum at the whee ls as
you depress the acce lerator .
Depending on the we ight of the rig (vehicle and trailer) and the
severity of the incline, yo u may roll backwards as you start. You can
prevent rol ling backwards by holding the park ing bra ke sw itch pulled
out and accelerating -just as you wou ld when starting on a hill with a
conventional hand brake .•
Emergency braking
In the event that the conventional brake system fails or
locks.
- P ull the swi tch and cont inue to pull it to s low your veh icle
with the parking brake in an emergency .
- As soon as you re lease the sw itc h or accelerate, the
braking process stops .
If you pull the switch and hold it above a speed of abou t 5 mp h (8
km/h), the emergency braking function is init iated. The vehicle is
bra ked at all fou r wheels by activat ing the hydraulic b rake system.
Brake performance is s imilar to making an emergency stop~,&.
So that emergency braking is not activated by mistake, an audible
warning tone (buzzer) sounds when the switch is pulled . As soon as
Controls and equip ­
ment Safety first
the switch is released, or the accelerator pedal is depressed, emer­
gency braking s tops.
& WARNING
Em erg ency braking should only be u sed in an emergen cy, wh en
the no rmal foot brake ha s failed o r the brake pedal i s obstructed.
U sing the park ing b rake to perform emerg ency braking will slow
your vehicl e as if you had made a full brake application . The laws
of phy sic s c annot be su spen ded even wi th ESP and it s ass ociated
c omponents (ABS, ASR , ED S). In corn ers and when r oad or
weather condit ion s are bad , a full brake application can cause the
