Securing the vehicle against rolling

Lug bolt lock

Principle

General information

The vehicle manufacturer recommends to ad-

ditionally secure the vehicle against rolling

away when changing a wheel.

The wheel lug bolts have a special coding. The

lug bolts can only be released with the adapter

which matches the coding.

Overview

On a level surface

Depending on vehicle equipment, store the lug

bolt lock adapter as follows:

▷

In the cargo area under the cargo area

floor.

▷

In the cargo area on the left or right side.

In the cargo area behind a side trim panel.

Place chocks or other suitable objects in front

and behind the wheel that is diagonal to the

wheel being changed.

On a slight downhill gradient

Unscrewing

1. Attach the adapter to the lug lock bolt.

2. Unscrew the lug lock bolt.

3. Remove the adapter after unscrewing the

lug bolt.

If it is necessary to change a wheel on a slight

downhill gradient, place chocks and other suit-

able objects, e.g., rocks, under the wheels of

the front and rear axles, against the direction

that the vehicle will move.

Screwing on

1. Attach the adapter to the lug lock bolt. Turn

the adapter until it fits onto the wheel lock

bolt.

2. Screw on the lug lock bolt. The tightening

torque is 101 lbs ft/140 Nm.

3. Remove the adapter and stow it after

screwing on the lug bolt.

Park the vehicle on solid and non-slip

ground at a safe distance from road traffic.

Turn on the hazard warning system.

Set the parking brake.

Warning

▷

Hands and fingers can be jammed when us-

ing the jack. There is a risk of injury. Comply

with the described hand position and do not

change this position while using the jack.

Turn the steering wheel until the front

wheels are in the straight-ahead position

and engage the steering wheel lock.

row 1, and grasp the jack crank handle or

lever with your other hand, arrow 2.

▷

Engage a gear or move the selector lever to

position P.

As soon as permitted by the traffic flow,

have all vehicle occupants get out and

make sure that they remain outside the

hazardous area such as behind a guardrail.

▷

If necessary, set up the hazard triangle or

hazard warning lights at an appropriate

distance.

Depending on vehicle equipment, remove

the wheel change set and, if necessary, the

emergency wheel from the vehicle.

2. Insert the jack into the rectangular recess of

the jacking point closest to the wheel to be

4. Take your hand away from the jack as soon

as the jack is under load and continue turn-

ing the jack crank handle or lever with one

hand.

After the wheel change

1. Tighten the lug bolts crosswise. The tight-

ening torque is 101 lbs ft/140 Nm.

2. Stow the faulty wheel in the cargo area, if

necessary.

5. Make sure that the car jack foot extends

vertically and is at a right angle beneath the

jacking point.

3. Check tire inflation pressure at the next op-

portunity and correct as needed.

4. Re-initialize the flat tire monitor or reset the

Tire Pressure Monitor.

5. Check to make sure the lug bolts are tight

with a calibrated torque wrench.

6. Drive to the nearest authorized service cen-

ter or another qualified service center or

repair shop, then have the damaged tire

replaced.

6. Crank the vehicle up until the entire jack

surface is on the ground and the cor-

responding wheel is lifted max. 1.2 in-

ches/3 cm above the ground.

Mounting a wheel

Mount one emergency wheel only, as required.

1. Unscrew the lug bolts.

2. Remove the wheel.

3. Put the new wheel or emergency wheel on

and screw in at least two lug bolts in a

crosswise pattern until hand-tight.

When non-original light-alloy wheels of the

vehicle manufacturer are mounted, the ac-

companying lug bolts may have to be used

as well.

4. Hand-tighten the remaining lug bolts and

tighten all lug bolts well in a crosswise pat-

tern.
