Tires and wheels
Read tire inflation pressure on tire 
gauge and check against the recom-
mended tire inflation pressure on the 
placard on the driver’s door B-pillar 
(
page 255). If necessary, add air to 
achieve the recommended tire inflation 
pressure.
Install the valve cap.
Repeat this procedure for each tire.Potential problems associated with 
underinflated and overinflated tires
Underinflated tire inflation pressure
Underinflated tires can:
cause excessive and uneven tire wear 
adversely affect fuel economy 
lead to tire failure from being 
overheated 
adversely affect handling 
characteristics
i
If you have overfilled the tire, release 
tire inflation pressure by pushing the 
metal stem of the valve with e.g. a tip of 
a pen. Then recheck the tire inflation 
pressure with the tire gauge.
i
The recommended tire inflation pres-
sures for your vehicle can be found on 
the tire placard located on the driver’s 
door B-pillar. The tire inflation pres-
sures are not listed in the Operator’s 
Manual.
Warning!G
Follow recommended tire inflation 
pressures.
Do not underinflate tires. Underinflated tires 
wear excessively and / or unevenly, 
adversely affect handling and fuel economy, 
and are more likely to fail from being over-
heated.
Do not overinflate tires. Overinflated tires 
can adversely affect handling and ride 
comfort, wear unevenly, increase stopping 
distance, and result in sudden deflation 
(blowout) because they are more likely to 
become punctured or damaged by road 
debris, potholes etc.
Do not overload the tires by exceeding the 
specified load limit as indicated on the plac-
ard on the driver’s door B-pillar. Overloading 
the tires can overheat them, possibly caus-
ing a blowout.
