own and your passenger's safety when chang­
ing a wheel.
• After you experience a tire failure, pull the
car well away from moving traffic and try to
reach
level ground before you stop c:> _&..
• All passengers should leave the car and
move to a safe location (for instance, behind
the guardrail)
c:> _&..

A WARNING
You or your passengers could be injured
while changing a wheel if you do not fol­
low these safety precautions:
-If you have a flat tire, move a safe dis­
tance off the road. Turn off the engine,
turn the eme rgency flashers on and use
other warning devices to alert other mo­
torists.
- Make sure that passengers wait in a safe
place away from the vehicle and well
away from the road and traffic.
- To help prevent the vehicle from moving
suddenly and possibly slipping off the
jack, always fully set the parking brake
and block the wheel diagonally opposite
the wheel being changed. When one
front wheel is lifted off the ground, plac­ ing the Automatic Transmission in P
(Park) will
not prevent the vehicle from
mov ing .

A wheel change is not complete without the
doing the following .
• Always store the vehicle tool kit, the jack*
and the replaced tir e in the luggage com­
partment ~
page 132 .
• Check the tire pressure on the spare wheel
i mmediately after mount ing it.
• As soon as possible, have the
tightening
torques
on a ll wheel bo lts checked with a
torque wrench. The correct tightening tor­
que is 90 ft lb (120 Nm).
• Have the flat tire
replaced as soon as poss i­
ble.
(D Tips
- If you notice that the wheel bolts a re
corroded and difficult to turn while
chang ing a tire, they should be rep laced
before you check the tightening torque.
- Drive at reduced speed until you have the
tightening torques checked.
- After changing a whee l, the tire pressure
in all four tires must be checked/correct­
ed and the tire pressure monitoring indi­
cator must be stored in the MMI

A WARNING ~
-You or your passengers could be injured
while changing a wheel if you do not fo l­
low these safety preca utio ns:
- Position the vehicle jack on ly at the
designated lifting points and align the
jack. Otherwise, the vehicle jack could
slip and cause an injury if it does not
have sufficient hold on the vehicle .
- A soft or unstable surface under the
jack may cause the vehicle to slip off
the jack . Always provide a firm base for
the jack on the ground. If necessa ry,
use a stu rdy board under the jack.
- On hard, slippery surface (such as t iles)
use a rubber mat or simi lar to prevent
the jack from slipping.
- Only raise your vehicle with the vehicle
jack provided by the fac to ry.
If you use
a vehi cle jack for another vehicle, your
vehicle can slide and cause injury.
- Changes in temperat ure or load can af­
fect the height o f the veh icle .
- Never start the engine when the vehi­ cle is raised, which co uld cause an acc i­
dent.
- Suppo rt the ve hicle securely with ap­
propr iate s tands if work is to be per­
formed underneath the vehicle; other ­

llll-

268 What do I do no w?
-Pull the reversible blade from the screw ­
driver before you use the hexagonal
socket in the handle to t urn the whee l
bo lts.
- When mounting tires with
unid ire ctional
t re ad design
make s ure the tread pat­
tern is pointed the right way
¢ page 268.
-The wheel bolts should be clean and easy
to turn. Check for d irt and corrosion on
the mat ing su rfaces of both the whee l
and the hub. Remove all dirt from these
surfaces before remount ing the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the right direction.
Using a spare tire with a tread pattern
int ended fo r use in a specific dir ection
When us ing a spare tire w ith a tread pattern
i ntended for use in a specific direction, please
note t he following:
- The direction of rotation is marked by an ar ­
row on the side of the tire .
-If the spare t ire has to be installed in the in­
correct direction, use the spare tire only
temporarily since the t ire will not be able to
achieve its optimum perfo rma nce character­
ist ics with rega rd to aquaplaning, noise and
wea r.
- We recommend that you pay particular at­
tent ion to this fact du ring wet weat her and
that you adjust your speed to match road
condit ions .
- Replace the fla t tire w ith a new one and
have it ins talled on your veh icle as soon as
possible to restore the handling advantages
of a unidirectiona l tire .
Notes on wheel changing
