Closing the engine hood
- Pull the hood down until the pressure from the struts is
reduced.
- Let the hood
drop down and latch in place. Do not try to
push it shut;
it may fail to engage=:> &.
& WARNING
A hood that is not completely latched could fly up and block your
view while driving.
• When you close the engine hood, check it to make sure the
safety catch has properly engaged. The hood should be flush with
the surrounding vehicle body parts.
• If you notice while driving that the hood is not secured prop­
erly, stop at once and close it. •
Working in the engine compartment
Be especially careful whenever you work in the engine
compartment.
Whenever you must perform any work in the engine compartment,
for example checking and filling different fluids, there is a risk of injury, burns and accidents. To prevent personal injury always
observe the following WARNINGS. The engine compartment of any
vehicle is a hazardous area=>& .
& WARNING
To help avoid injury, before you check anything under the hood:
• Turn off the engine.
• Remove the ignition key.
• Apply the parking brake.
Safety first
& WARNING (continued)
• Move selector lever to "P" (Park).
• Always let the engine cool down. Hot components will burn
skin on contact.
• To reduce the risk of being burned, never open the hood if you
see or hear steam or coolant escaping from the engine compart­
ment. Wait until no steam or coolant can be seen or heard before
carefully opening the hood.
• Keep children away from the engine compartment.
• Never spill fluids on hot engine components. They can cause a
fire. • Never touch the radiator fan. The auxiliary electric fan is
temperature controlled and can switch on suddenly.
• Never open the coolant reservoir cap when the engine is still
warm. The coolant system is pressurized and hot coolant could
spray out.
• Protect your face, hands and arm from steam or hot engine
coolant by placing a thick rag over the cap when you open the
coolant reservoir.

increased tire wear and can affect the handling of the vehicle and
stopping ability.
• Incorrect tire pressure s and/or underinflation can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing loss of vehicle control.
• The driver is responsible for the correct tire pressures for all
tires on the vehicle. The applicable pressure values are located on a sticker on the driver's side B-pillar.
• Only when all tires on the vehicle are filled to the correct pres­
sure, the tire pressure monitoring system can work correctly.
• The use of incorrect tire pressure values can lead to accidents or
other damage. Therefore it is essential that the driver observe the
specified tire pressure values for the tire s and the correct pres­
sures for the function of the tire pressure monitoring system.
• Always inflate tires to the recommended and correct tire pres-
sure before driving off. .,_
