cluster displayPractical hints Car care Index
Stopping
For brief stops, e.g. at traffic lights, leave the 
transmission in gear and hold vehicle with the service 
brake.
For longer stops with the engine idling, shift into “N” 
or “P” and hold the vehicle with the service brake.
When stopping the vehicle on an uphill gradient, do not 
hold it with the accelerator, use the brake. This avoids 
unnecessary transmission heat build up.
Maneuvering
To maneuver in tight areas, e.g. when pulling into a 
parking space, control the vehicle speed by gradually 
releasing the brakes. Accelerate gently and never 
abruptly step on the accelerator.
To rock a vehicle out of soft ground (mud or snow), 
alternately shift from forward to reverse, while applying 
slight partial throttle.Rocking a vehicle free in this manner may cause the 
ABS or traction system malfunction indicator lamp to 
come on. Turn off and restart the engine to clear the 
malfunction indication.
Wa r n i n g !
Getting out of your vehicle with the selector lever 
not fully engaged in position “P” is dangerous. 
Also, when parked on an incline, position “P” alone 
may not prevent your vehicle from moving, 
possibly hitting people or objects.Always set the parking brake in addition to shifting 
to position “P”, see page 256 for parking brake. When parked on an incline, also turn front wheel 
towards the road curb.When leaving the vehicle always remove the key 
from the steering lock, and lock the vehicle. Do not 
leave children unattended in the vehicle, or with 
access to an unlocked vehicle. Children could move 
the selector lever from position“P”, which could 
result in an accident or serious injury.

Electronic stability program (ESP) — warning lamp
The yellow ESP warning lamp in the 
speedometer dial comes on with the

been detected in the system. Pressing the accelerator 
pedal will require greater effort. Only partial engine 
output will be available.
See electronic stability program (ESP) on page 274 if the 
warning lamp lights up or flashes when the vehicle is 
moving.Seat belt nonusage warning lamp

position 2, the seat belt nonusage warning 
lamp comes on, and a warning sounds for a 
short time if the drivers seat belt is not fastened.

warning lamp blinks for a brief period to remind the 
driver and passengers to fasten seat belts.

311 Fuses
Te ch n i c a l
data Instruments 
and controlsOperation DrivingInstrument 
cluster displayPractical hintsCar care Index Stowing things in the vehicle Fuses
Most of your vehicle’s electrical components are fused 
with safety fuses. With the exception of the brake lights, 
all individual lighting system components are 
electronically fused. Before replacing a blown safety 
fuse, determine the cause of the short circuit. Always 
observe amperage and color of fuse.
The circuit for components is protected by a cycled 
circuit breaker interrupted if too much current is being 
drawn. The circuit closes automatically after a short 
time; the circuit is broken again if the malfunction 
reoccurs.
Always use a new fuse for replacement. Never attempt to 
repair or bridge a blown fuse.
A fuse chart is located in fuse box (1).
A special fuse puller is located in the auxiliary fuse box 
in the trunk, see page 314.
Wa r n i n g !
To help avoid personal injury during a collision or 
sudden maneuver, exercise care when stowing 
things. Put luggage or cargo in the trunk if 
possible. Do not pile luggage or cargo higher than 
the seat backs. Do not place anything on the shelf 
below the rear window.
